What is the filler in the filler manufacturer?
Fillers in filler manufacturers are also referred to as fillers, extenders. Some fillers are also body pigments. The filler of the micro-nucleus has excellent hiding power and is often used for coating work. Fillers can be used in a variety of polyurethane products, such as polyurethane coatings, sealants: polyurethane pastes, and particularly elastomeric i polyurethane foams. Melamine plant fiber polymerization, soap ginseng polyol, etc., organic filler can be used for polyurethane foam; calcium carbonate kaolin (ceramic, porcelain clay), molecular sieve powder talc powder wollastonite titanium dioxide j barite powder (barium sulfate) and so on Inorganic powders can be used as fillers for polyurethane sealants, polyurethane soft foam polyurethane elastomers, adhesives, polyurethane coatings, and the like. Refers to materials that are filled in other objects. In chemical engineering, a filler refers to a lazy solid material contained in a packed tower, such as a Pall ring and a Raschig ring, etc., which functions to increase the gas-liquid contact surface and mix them vigorously with each other. In chemical products, fillers, also known as fillers, refer to solid materials used to improve processing functions, mechanical properties of products, and/or cost reduction. In the meantime, fillers which can significantly advance the strength of the product, such as long fibers and whiskers, are often referred to as reinforcing materials, and carbon black is called reinforcing filler. Pharmaceutical tablets, cosmetics and detergents often participate in solid materials and calcium carbonate as fillers, but the intention is to schedule the dose and concentration instead of improving the function, so it should be called thinner. Plastic plasticizers, rubber oil-filled oils, and spinning oils, etc., can improve the utility and can also affect the cost, but it is customary to regard these liquid materials as processing aids.
In polymer chemicals, fillers (fillers) are highly used additives, and almost all plastics (including thermoplastics and thermosets), natural rubbers and coatings use many fillers. For example, filler manufacturers participate in wood powder, clay or calcium carbonate in the manufacture of plastics, not only can improve the mechanical function of the product, add hardness, but also reduce the cost; with graphite, magnetic powder or mica as filler, can travel the conductive, plastic Magnetic and heat resistance; participation in carbon black or silica (silica) in rubber can significantly advance the physical properties of the product; participation in titanium dioxide (titanium dioxide) in the spinning solution can block and dye. In the coatings industry, white or colored fillers (such as titanium dioxide, talc, calcium carbonate, barium sulfate, etc.) are often used to improve the optical, physical and chemical functions of coatings. The fillers (fillers) used in such applications are called body pigments or Exhibition color.
