Calcium carbonates for microporous breathable films market and product requirements
In 1983 microporous films were developed in Japan for the hygiene market. the microporous films quickly developed to become a large majority of the product lines in infant and adult health care. The use of mineral fillers it the fabrication process of breathable films has allowed a considerable development of these type of films, especially for hygienic films. For the breathable films Omya, the world-wide leader of CaCO3 developed a special range of CaCO3 fillers. the more common way to produce microporous films is to use a 43 52 % CaCO3 by weight polyolefin ompound and to produce a stretch film which will present micropores in the structure. In the microporous films the water vapour migrates through the film by following the conduit build thanks to the geometrical arrangement of the CaCO3 particles, as well as the film providing a barrier to liquids. The water vapour transmission ratio (WVTR) will be improved by playing on the thickness of the film, or i.e. on the composition of the polymers, the filler content of CaCO3 or the choice of CaCO3. The microporous films have two main outlets: The hygiene application with diapers films for infants, sanitary napkins or adult incontinence or construction application for house wraps, wall covering and under-tile roofing films. Depending upon the application, the tensile strength elongation and tear strength values are predefined for the non laminated films. Far a constant Thickness of films, the choice of the resin but especially the CaCO3 choice is fundamental in deciding the final values. Good acid, alkali and UV resistance is usually required for films used in the construction industry. Selecting the right polyolefin and the appropriate CaCO3 ensure these properties.
To fulfil the films requirements of which CaCO3 is playing the most important role, the choice of CaCO3 is very determinant. This CaCO3 will influence: the visual aspect, the colour, the WVTR and the mechanical properties. The average market growth is estimated at 5 % for building application and approx. 3 % for hygienic activities. In 2001 the replacement level of the traditional films in the hygienic sector through microporous films amounts to 53 % in Europe, 38 % in Asia and 51 % in the USA. The growth of the microporous films market is essential derived from infant diapers. Female care as well as adult incontinence should be mainly represented by microporous film. The global tonnage of microporous films should amount in 5 years to approx. 400000 tons, even though today it is only 175000 tons.

Vietnam Mineral Resources and White Limestone exploitation in Vietnam
Vietnam Mineral Resources and White Limestone exploitation in Vietnam
As results of the survey, evaluation and exploration of minerals, Vietnam has quite diverse and rich mineral resources with over 5,000 mines and ore points of 60 different types of minerals; There are a number of minerals of considerable reserve scale, world-class, of strategic significance and a resource for the country's socio-economic development.
Expoiltation of white limestone in Tan Ky Mineral Processing Joint Stock Company
Article 53 of the Constitution in 2013 affirms that mineral resources are "public property" owned by the entire people, uniformly managed by the State. On average, each year, our country's mining industry provides about 90 million tons of cement limestone, about 70 million cubic meters of common construction materials (construction materials), nearly 100 million cubic meters of construction sand and sand, over 45 million tons of coal, over 3 million tons of iron ore, etc ..; output value of the mining industry (excluding petroleum) accounts for about 4-5% of the annual GDP; Directly contributing to the budget from the grant of mining rights, royalties and environmental protection fees (excluding oil and gas) from 2014 to now on an average of VND 16-20,000 billion per year, including taxes resources from VND 10,000 - 11,000 billion. It can be said that mineral resources have actually become one of the resources for socio-economic development of the country in each period.
Titanium ore: Titanium ore in Vietnam includes 02 types of original ore and placer ore. The original ore concentrates in Thai Nguyen province; the mineral ores are concentrated in the coastal provinces from Thanh Hoa to Ba Ria - Vung Tau. The total potential of titanium resources and reserves in Vietnam is about 663.15 million tons of useful heavy minerals.
Bauxite ore: Bauxite ore in Vietnam is distributed mainly in the northern provinces (Lang Son, Cao Bang, Ha Giang) and in the Central Highlands (Dak Nong, Lam Dong, Gia Lai, Kon Tum) and Binh Phuoc and Phu provinces. Yen. The reserve and forecast resources of bauxite ore deposits in the Northern provinces are about 88.5 million tons. For bauxite laterite ore, the total reserves and forecast resources of bauxite-laterite ore have been estimated at about 3,500 million tons of fine ore.
Rare earth: Rare-earth ores are concentrated in Bac Nam Xe, Nam Nam Xe, Dong Pao (Lai Chau), Muong Hum (Lao Cai) and Yen Phu (Yen Bai) mines. According to statistics, reserves and rare earth resources in Vietnam reached about 19.96 tons of Tr2O3.
Apatite: So far, 17 apatite mines and ore points have been confirmed, concentrated mainly in Lao Cai province. Most apatite mines are of medium to large scale. The reserve and forecast resources of apatite ore calculated to a depth of - 900m are 2,373.97 million tons.
White sand: White sand is distributed in 09 coastal provinces of North and Central Vietnam with great potential but the level of investigation and evaluation is limited. The total reserves of 13 mines have been explored at 123 million tons, the forecast resource is about 03 billion tons.
High quality limestone (except white marble): Limestone meets the requirements of cement production, industrial lime and soda are present in 29 provinces of the country but unevenly distributed, concentrated mainly in North and North Central region. Now, more than 80 mines have been surveyed, assessed and explored at different levels with a total reserve of about 08 billion tons.
White marble: Distributed in 11 northern provinces, but concentrated in Nghe An and Yen Bai provinces. Up to now, there are over 70 mines already under exploration. About 200 million m3 of white marble have been identified as eligible for paving stone production and 1.2 billion tons are of sufficient quality to produce calcium carbonate powder.
Mineral water - hot water: Almost all provinces and cities in the country have mineral water - hot water. So far investigated, recorded 400 sources of mineral water - hot water.
Uranium ore: Results of geological research and mineral exploration have discovered uranium mineralization in the Northwest, Viet Bac, Central and Central Highlands regions. In particular concentrated in the region of Nong Son (Quang Nam). To date, 06 uranium mines have been evaluated and explored with a total estimated resource of about 218,000 tons of U3O8, of which Nong Son area is about 100,000 tons of U3O8.
Coal: Coal is distributed mainly in the Northeast coal basin and Song Hong coal basin. In addition to the exploited coal reserves, if excluding the Red River basin coal, the remaining reserves and resources are not large (about 5 billion tons including forecast resources).
Regarding Song Hong coal basin, currently investigating and evaluating the overall coal potential of the land. Initial results show that the coal potential in the mainland of the Red River basin is very large, the density of coal storage is high from -330 to -1200m. Distribution ranges from Khoai Chau Hung Yen to Tien Hai, Thai Binh - Hai Hau Nam Dinh. Preliminary results have identified good quality coal for use as energy coal.
In addition, our country has a number of other metallic minerals such as copper ore, iron ore, manganese, antimony, mercury, molybdenum, feldspar, kaolin, kalin clay as raw materials for ceramic, paving stone, etc. Detecting and assessing the potential of resources, but the resources of these minerals are not large and scattered
As reported by the General Department of Geology and Minerals of Vietnam, marble (white limestone) is a mineral used in many different fields. Survey results showed that marble is quite widely distributed in the territory of Vietnam but concentrated large reserves in some localities such as Yen Bai, Nghe An, Bac Can, Ha Giang, Tuyen Quang.
According to statistics, after more than 3 years of implementing the marble mining plan, there are currently 97 licenses of this type of mineral activity in operation, including 47 exploration licenses with forecast reserves of 177 , 7 million m3 of paving stone, 624 million tons of powder stone and 50 mining licenses with the licensed reserve of 161 million m3 of paving stone, 428 million tons of stone making calcium carbonate sets; The annual exploiting capacity for paving stone is 5.8 million m3 and 16 million tons of powder stone, many times higher than the planned output.
Marble exploitation and processing activities in localities have contributed to socio-economic development, creating jobs and income for a part of local people. However, the white marble mining industry still faces many difficulties due to the lack of strict sanctions for mineral exploration practice, which leads to many organizations and individuals lacking of experience for exploration ...
Therefore, many mines, when being put into operation, are not the results of the assessment of reserves, leading to investors' losses and ineffective business, causing widespread exploitation, wasting resources, scrambling for areas, and especially greatly affect the landscape environment and infrastructure. The number of marble processing facilities is quite large, but it is small in scale, scattered and outdated technology equipment, thus, inappropriate use of resources.
In quarry mines, only 20 - 30% of the finished stone is recovered, 70 - 80% is still unused, and must be left at mines showing waste, large and potential source of landslide, unsafe in exploitation; The number of mineral activity licenses is quite large, while the State and mineral management forces are small, the post-licensing examination and inspection does not meet the requirements of management and sanctions for administrative violations. The law violation is not strong enough ...
Speaking at the Meeting, Deputy Minister Nguyen Linh Ngoc said that “ our marble mining industry to really develop, avoid wasting resources and protect the environment, it is necessary to have a strong and responsible participation, More responsibilities of local authorities, consultancy agencies, assigning enterprises to invest in mining. On the business side, there should be joint ventures and partnerships to avoid the strong situation that everyone does now leads to unhealthy competition.
At this conference, businesses need to discuss and propose a series of products from the exploitation of white stone, based on the strengths of each unit to exploit effectively (possibly based on the establishment of the Marble Association. ). There are thus newly built strong brands from Vietnam white marble products. For monolithic stone currently banned from export, it is necessary to find new directions and new markets from the manufacture of monolithic marble to high economic and fine art products. The Deputy Minister emphasized that this conference is also an opportunity for businesses to propose problems and mechanisms for the Ministry of Natural Resources and Environment to continue to submit to the Government to remove difficulties for businesses and best serve the economy. sacrifice to the country.

The production of calcium carbonate (GCC and PCC) continues to grow driven primarily by the growth of the paper industry. Asia is emerging as the hotspot of paper industry, with China in particular, witnessing a slew facility establishments by some of the world’s leading producers in recent times. With the demand rising from Asian Markets, Malaysia, Vietnam and Thailand are emerging as new source nations for the supply of raw materials. On the other hand, Europe is also witnessing a shift in production activity, with Central European countries emerging as major production centers as region’s companies look to cut down on operational expenditure.
China has been at the forefront of the rise in production output for both GCC and PCC production of GCC commenced in the 1990s. and since then the country’s production has expanded rapidly. During the period 2008-2011, China’s production of GCC and PCC increased by above 8% with most of the output registered for dry ground calcium carbonate DGCC that finds use in plastics industry. The past decade has been witness to the establishment of several large-scale paper mills in China, which have also established satellite WGCC (wet ground calcium carbonate) plants that used locally available marble deposits.

Indian calcium carbonate caco3 market 2020
Calcium Carbonate is an odorless, colorless and tasteless chemical compound with the formula CaCO3. It is a common substance naturally found in limestone, calcite, aragonite, chalk, marble, pearl and oyster, and can be found in geological, biological and extra-terrestrial sources, including rocks, shells of snails, corals, craters, etc. It is commonly obtained by the means of mining or quarrying, and can also be produced by using calcium oxide as a raw material. Calcium carbonate are used across various industries such as paper, plastics, paints & coatings, personal health, food & beverage, construction, etc. In addition, it is also used in the purification of iron from iron ores, as a filter cake-sealing agent in oil industry, pH control in swimming pools, refining of sugar from sugar beet, filler for latex gloves, neutralising acidic soil and in eradication of harmful sulphuric and nitric acid emissions in fossil fuel power plants by means of process called flu gas desulphurization.
Calcium carbonate has historically been one of the preferred fillers for the paper industry. In recent years, it has also become a preferred filler for the paint industry, heavily substituting kaolin in this application. While the primary reason has been the unavailability of high-quality kaolin, customers are also shifting due to the better opacity, gloss, and scrub resistance provided by calcium carbonate. While paint and paper are likely to remain the main application focus for calcium carbonate, relatively higher growth in segments such as Poly Vinyl Chloride (PVC) and masterbatches offer significant potential for a supplier to target, primarily due to the large expansion plans of companies such as Plastiblends and Finolex in India. Additionally, there is significant import substitution potential for steric coated grades of Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC) in masterbatches and PVC applications.
The key challenge suppliers face today is delivering high product performance in what has become a highly commoditized market. Inclusion of niche grades (such as steric coated for masterbatches and PVC) and application development along with the end user has to be the focus for suppliers looking to make premium offerings and improving their margins. However, this can only be in addition to the high-volume sales of commodity grades, as the potential to make premium calcium carbonate offerings in India remains low.
The demand for PCC is limited by its niche application segments and its price. Even though PCC finds niche usage in applications such as pharmaceuticals and oral care, there are alternate fillers also which are also fulfilling the needs of the respective industry. As a result, GCC accounts for 85% of the calcium carbonate consumed today, while PCC is only 15% of the nearly 3 million MT market size. This market is serviced by 4 large-scale calcium carbonate producers that account for around 30% of the market and an additional 20%–22% of the demand is met by imports. The remainder of the market is fragmented and is catered to by medium, small-scale, and unorganized producers.

Ground calcium carbonate for latex films. The Effect of Grounded Calcium Carbonate on the Physical Properties of NR Vulcanised Latex Films
(Ground calcium carbonate )The effect of filler loading on tensile strength, force at break, modulus, stress-strain relationship and surface morphology of natural rubber latex (NRL) films was studied. Grounded calcium carbonate (GCC) loaded into NRL latex compounds and the results obtained from latex films formed from these compounds, showed that their tensile strength and force at break improved initially but leveled and dropped when the GCC loading is more than 5% in NRL films. Disturbing the filler arrangement in the rubber matrix by scragging the test piece of filled NRL films changed the elastic constant value (C1) of the filled test pieces with a large difference in highly filled films. Expected agglomeration of filler in gloves visualised via the microscopy technique indicated disinclination of GCC to distribute well in NRL films. The discrepancy seen in SEM micrographs between differently filled films could be related to surface roughness of the NRL films. Among filled NRL films, the one containing 20% of GCC had the smoothest appearance in its surface morphology. Micrographs from FIB-SEM techniques show clear clustering of fillers at high dosages in the NRL films.
Keywords: Natural rubber latex; filler; calcium carbonate
Compounded natural rubber latex (NRL), due to its dried film characteristics, is normally the preferred material for producing thin rubber products. Among the common products from NRL are latex gloves, balloons, condoms and catheters. The peculiarities seen in NRL films such as high elasticity and flexibility at low modulus compared to films made from dry bulk rubber, give an advantage to NRL in meeting the usage demands of these NRL products. Most products are to meet a set of minimum quality requirements based on their application to ensure safety in usage. It is undeniable that a main contributor to the cost of producing NRL gloves is the bulk material in the gloves. The rubber content in NRL gloves of more than 95% is believed to be one of the reasons for the high strength superiority of NRL gloves. However, in recent years, due to the increased price of NRL, filler is added into latex to cheapen material cost. Surprisingly, these filled gloves meet the minimum requirements of current regulatory limits; hence, they are acceptable to consumers. With this attractive savings in cost, glove makers are pushing the limit of fillers in NRL gloves. Cai et al. 5 were among earlier workers reporting that ultrafine calcium carbonate could effectively improve tear strength, tensile strength and modulus of the NRL films. Improved modulus reflects an increase in stiffness of NRL films. It is thought that further stiffening an elastic thin product by incorporating high levels of a nonelastic material such as a filler, may render the product useless for its purpose. Therefore, this paper is intended to demonstrate this effect on NRL films.
SUMMARY
The application of GCC affects the properties of NRL films. The tensile strength and force at break values improved at low levels of GCC but dropped when GCC loading is more than 5% in NRL films. The elastic constant of unscragged NRL films increased with filler loading. Scragging disturbed the filler arrangement and the reinforcement mechanism diminished. SEM technique allows visualisation of surface smoothness of NRL films due to filler addition. However, this observation is inconsistent as only the film with 20% GCC appeared to be smooth as seen in the SEM micrograph, while FIB-SEM provides a better relationship between differently filled NRL films with more spots due to filler clustering as observed with increased GCC levels in the NRL films.

How Calcium Carbonate is used in PVC Pipe ?
What is a PVC Pipe?
PVC pipes are made out of a material known as polyvinyl chloride, a durable, strong plastic-like substance. Pipes are constructed from this material and used in various applications from plumbing to construction. The pipe is designed to be universal. All pipes are designed around specific requirements to ensure that multiple pipe sections will fit together. The ends of the pipe can either be smooth or grooved (similar to a screw). Additionally, there are several different pipe sizes ranging from very small (one-fourth inch) to very large (10 feet).
What is PVC Pipe Used For?
PVC pipes are commonly used for manufacturing sewage pipes, water mains and irrigation. Possessing very long-lasting properties, PVC pipes are easy to install, lightweight, strong, durable and easily recyclable, making them cost-efficient and sustainable. The smooth surface of PVC pipes also encourages faster water flow due to lower amounts of friction than piping made from other materials such as cast iron or concrete.
How are PVC Pipes Made?
PVC pipes are manufactured by extrusion of raw material PVC, and generally follow the same steps of typical pipe extrusion operations:
- Feeding of raw material pellets / powder into the PVC twin screw extruder
- Melting and heating in multiple extruder zones
- Extruding through a die to shape into a pipe
- Cooling of the shaped pipe
- Cutting of PVC pipes to the desired length
However, despite having a similar manufacturing procedure to most plastic piping, PVC pipes have intrinsic characteristics that pose additional challenges to pipe manufacturers both in terms of production, as well as positioning their products on the market.
The Challenges of PVC Pipe Manufacturing
Increased Extruder Friction
Due to the nature of PVC plastic, PVC extruders are subjected to high amounts of friction and stress. This means that to guarantee a long service life, PVC pipe production lines require the use of specialized extruders that utilize a twin screw extruder configuration, as well as featuring robust construction materials that can withstand the harsh PVC extruder operating conditions.
Differentiating From Competitors
Since PVC piping is one of the most used types of piping, there is a lot of competition between manufacturers. It is therefore of paramount importance for PVC pipe producers to differentiate themselves from their competitors, both in terms of delivering consistent product quality, as well as offering a wide range of products at competitive prices. Such differentiation can only be achieved through the use of world class manufacturing equipment, that maximizes productivity while minimizing costs and has the capacity to produce a wide variety of PVC pipe sizes. DRTS offers a range of effective turnkey solutions that guarantee this type of effective operation, such as equipment with integrated Industry 4.0 functionality, advanced connectivity, ease of integration and multi-layer die heads that maximize savings.
PVC pipe compounds typically contain varying amounts and types of calcium carbonates, paraffin waxes, and other ingredients such as stabilizers, titanium dioxide, calcium stearate, and processing aids. the effect of calcium carbonate particle size, coating, and usage level on the properties of PVC pipe depends on quality of Calcium carbonate (purity, whiteness, hardness, particle size,...)
