What is calcium stearate emulsion?
Calcium stearate emulsion is a kind of white viscous water-based liquid containing about 50% calcium stearate. The particle size of calcium stearate after hydration reaches micro-nanometer state. It is an excellent lubricant and can reduce interfacial tension. It can greatly improve the smoothness and fluidity of the wet coating surface, flatten it and spread easily, and can improve the coating adaptability of the coating.
The surface of the coating is improved by giving certain plasticity and slippage to the dry coating, and the performance of the finished coating is improved by reducing or eliminating fuzz and powder.
What are the advantages of calcium stearate emulsion
Waterborne calcium stearate products have the advantages of stable performance, non-toxic, tasteless, no pollution, and fully meet the requirements of environmental protection products advocated by the state.
Secondly, waterborne calcium stearate completely avoids the problem of dust pollution in use, makes the product more widely used, and reduces the production and operation cost of enterprises.
Waterborne calcium stearate products are mainly used in papermaking, polyvinyl chloride, rubber and plastic lubricants, release agents and heat stabilizers.
Application fields of calcium stearate emulsion
1. Paper industry: as the lubricant of the paper coating layer, it can improve the lubricity and hydrophobicity of the coating surface, improve the lubrication and fineness of the coating, make the paper smooth and smooth, and prevent cracking after drying.
2. Printing industry: Super calender can prevent powder and hair loss in the process of cutting and printing, thus improving the appearance and printing performance of the paper.
3. Polyurethane demoulding: it can be used for RIM reaction injection molding, PU foam and high resilience opening to improve the hardness of the film.
And does not affect the surface color, adhesion, paint ability and so on.
4. Rubber industry: as plasticizer in rubber processing, it can soften natural rubber and synthetic rubber, but has almost no effect on vulcanization.
5. Metal processing: lubrication treatment of metal materials during cold extrusion, cold stamping and cold drawing.
It is especially suitable for workpieces with large degree of introduction, high deformation rate and complex curved surface.
6, soft products processing: also used for food packaging, medical devices and other non-toxic soft films and appliances.
It can also be used as a halogen absorbent for polyethylene and polypropylene to eliminate the adverse effects of residual catalysts on color and stability.
7. Hard product processing: when combined with basic lead salt and lead soap, the gelation speed can be improved.
8. Plastic processing industry: it can also be used as heat stabilizer for polyvinyl chloride and lubricant and release agent for many kinds of plastic processing.
9. Other industries: also used as lubricant for polyolefin fiber and molded plastics, thickening agent for grease, waterproofing agent for textiles, smooth agent for paint, plasticizer for manufacturing plastic records, etc.
It is also used in pencil lead production and medicine, spices and other products.
