About The Product

 

We are offering China Clay, which is useful for various industrial applications, usually falls under the Kaolinite group of clays and is formed because of the process of weathering or hydrothermal alteration of felspathic rocks. It is known for better service life, proper packaging and has the general formula Al 2, (Si 2 O 5 ) (OH) 4 . It is known for its’ accurate composition, is properly tested and is a hydrated alumino-silicate having sheet structure. Our products are known for fine quality, optimum usage and Free Silica (grit) being a highly undesirable impurity, is adequately removed during processing by levigation, sedimentation or air-separation.

Deposits

 

China clay has established itself as a very useful product and high grade china clay deposits are present in West Bengal, Orissa, Rajasthan, M.P. & Gujarat. Our personnel are very experienced and they collect the samples from different mines which are analyzed for proper composition and physical and chemical properties. The process goes further and its suitability for different applications is also studied. Moreover, we always follow industry leading guidelines and continuous availability of the material with no variation from mines remains our topmost priority; so as to maintain consistency in the final product.

 

Processing

 

We are known for adhering to high quality standards and the raw china clay is then subjected to a refining process which consists of spiral classification, hydrocycloning, deflocculation, bleaching and finally drying, micronizing, air-classification and surface treatment. We test the products on different quality standards and our processing ensures consistent composition, control of top-cut and average particle size and freedom from free silica.

 

Our highly experienced personnel cater to varied demands of clients’ and our quality assurance system extends from mining to micronizing to ensure completely Zero-defect products.

 

Mining

 

• Manual sorting to recover white lumps.
• On site chemical analysis before dispatch to our factories.

 

Micronizing

 

• Test for physical properties like Bulk density, Oil absorption, Whiteness etc.
• Particle - size distribution analysis.

 

Surface Treatment

 

• Testing of hydrophobicity, oil absorption and uniformity of coating.

 

Quality Test Certification

 

• Quality Test Certificate is provided to customers, certifying values within specifications.

 

Services

We are reputed for providing remarkable quality Aluminum Silicate having the general formula Al 2 SiO 3. Our range is processed from top notch technology and is used as filler and anti settling agent in paint and in the form of semi reinforcing agent in rubber. It is being offered in various forms, is tested on different quality standards and could be manufactured from precipitation or from processing of the naturally occurring aluminum silicate minerals. The precipitated variety is known for offering optimum usage, is stored in fine conditions and gives better properties due to smaller particle sizes and higher white strength value.

 

MANUFACTURING PROCESS

 

Our highly experienced personnel precipitate the Aluminum Silicate in large tanks. The process is extended and the product is then filtered, washed, dried and micron zed in highly advanced plants, in order to prevent any sort of contamination. Our R&D department has been consistently involved in researches, and they have developed a precipitation process, in order to provide accurate control of particle size and surface area. We always cater to the industry leading standards and the properties have been optimized in our various grades as per the application.

 

ADVANTAGES OF OUR PRODUCTS IN PAINTS

 

• Part of white pigment like Titanium-dioxide (10% or more) can be replaced without loss of opacity.
• They are able to provide faster surface and through-drying in product which also stands up better to abrasive treatment.
• Excellent substrates for high gloss finishes as they ensure good leveling out.
• These products act in the form of anti-setting agents for pigments and fillers. The viscosity of decorative paints consisting of our product is highly constant over extended periods of time. Due to their basic nature, they also have positive effect on storage stability.
• They are able to provide excellent thicksotropy and facilitate dripless application.
