Description
Levigated China Clay :
We usually process raw kaolin by a high-tech washing system to have Pure grade of china clay and remove impurities from the kaolin, this process is also called as levigation process. This levigation process helps to have a common kaolin grade with balanced and better physical and chemical properties after removing impurities like silica, iron, titanium, etc.
We have different grades of levigated china clay as per the client’s requirement we provide the following grades on the basis of the SLM value mentioned below:
Applications :
Paints :
It is used in various paints like distempers, cement primer, wood primer, texture paint, spray plaster, putties, and fillers undercoats.
- China clay due to its lamellar structure imparts toughness to coatings and tends to reinforce the films.
- It settles slowly in water and has low solubility in water, it is commonly used in water-based paints.
- Due to its low solubility in the aqueous phase and its ability to impart good brushing and levelling characteristics, it is mainly used in latex paints.
Adhesives Sealants :
In adhesive sealants, china clay gives good barrier effects and rheology control. The controlling rheology influences the speed at which adhesive can be applied which is important in high-speed paper laminating processes. The low surface hydroxyl content of calcined China clay leads to a low moisture pick-up, resulting in an excellent performance in moisture-sensitive sealant applications. Calcined clay is also effective as a structure-building component.
Plastic :
It is used as a filler in combination with others to impart strength and smoothness in the Plastic Industry for PE master batch; PE cables; PE film; PVC cables; PVC extrusions; PVC plastisols; PP mouldings; polyamide moldings; PBT/PET moldings; unsaturated polyester; urea-formaldehyde; phenol-formaldehyde.
Ceramics :
China Clay is also called KAOLINE, it is one of the essential Raw materials for ceramic Industries. China Clay does not swell on adding water Alumina present in Clay does not form Isomorphous series with any other metallic compound. It is naturally hydrated Aluminum Silicate and is one of the most abundantly available clays in the Earth’s crust. China Clay is the heart of potteries, tiles, ceramics, Glazes and many other industries.
Glass :
China Clay can be effectively used in the manufacturing of fibreglass because of its high alumina content.
Paper :
It is used in a variety of papers, cardboard, hard boards and others.
Rubber :
Grit-free china clay having low bulk density, and possessing reinforcing properties, is used as filler and to improve tensile, flexural modules make significantly increase.
Electrical Industry :
It is used for Electrical insulation, High voltage insulation components, electrical wires, EPDN rubber and others.
Cosmetic Soap :
China Clay is used in toothpaste, cosmetics and soap industry.
Other Uses :
China clay is used in white cement, Refractory bricks and in port, it acts as fog removing agent, dust-collecting agent on the road and fireproof agent for textiles.
Note :
Specifications and chemical analysis can be furnished only when we get to know the grades/applications desired by you.
