Coating classification: aluminum alloy casting coating

Core tip: Introduction: talcum powder and diatomite are selected as refractory aggregate for aluminum alloy casting coating, sodium bentonite and sodium carboxymethylcellulose (CMC) are used as composite suspension agent, silica sol and polyacrylamide (PAM) are used as composite binder, and water is mainly used as carrier Aluminum alloy casting coating is a kind of water-based coating with excellent performance and low cost As a new type of industrial coating, coating on the surface of aluminum alloy has the functions of protecting metal abrasives, facilitating the demoulding of castings, improving the surface quality of castings, improving the molding of castings, controlling the heat transfer rate of mold wall interface, etc Features: aluminum alloy casting Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: Introduction: talcum powder and diatomite are selected as fire-resistant aggregate for aluminum alloy casting coating, sodium bentonite and sodium carboxymethylcellulose (CMC) as composite suspension agent, silica sol and polyacrylamide (PAM) as composite binder, mainly water as carrier Aluminum alloy casting coating is a kind of water-based coating with excellent performance and low cost As a new type of industrial coating, coating on the surface of aluminum alloy has the functions of protecting metal abrasives, facilitating the demoulding of castings, improving the surface quality of castings, improving the molding of castings, controlling the heat transfer rate of mold wall interface, etc Features: the features of the aluminum alloy casting coating are as follows: 1) the aluminum alloy casting coating has excellent weather resistance and durability; 2) the aluminum alloy casting coating has excellent light retention and color retention; 3) the film of the aluminum alloy casting coating is tough and glossy; 4) the aluminum alloy casting coating is not easy to be powdered, yellowing and decorative; 5) Aluminum alloy casting coating has good chemical resistance and water resistance; 6) aluminum alloy casting coating is resistant to mineral oil, vegetable oil, petroleum solvent and petroleum products; 7) aluminum alloy casting coating has good impact resistance and wear resistance; usage: mould preparation First, the mold must be cleaned, the old coating and adhesive on the mold must be removed, and the sand shall be dropped to roughen the surface, and the mold shall be evenly heated to 250-350 ℃ (if the mold is just removed from the production line, it shall be cooled, cleaned, and then heated), and then cooled to 170-200 ℃ before spraying Mix the paint thoroughly again, pour out the required amount of dilution (1:3-5), and continue mixing for a period of time until it is uniform Spray the hand-held spray gun, keep the distance between the spray nozzle and the mold about 20-30 cm, and move the spray gun parallel and at a constant speed The coating shall be foggy after spraying The ideal coating is a thin 3-4 layer instead of a thick 1-2 layer Spray the first layer, dry the second layer, and so on The parts with high requirements for heat preservation shall have a thicker coating, and the parts requiring fast cooling shall even be sprayed with a thin layer Generally, the coating thickness is 75-125 μ M Scope of application: aluminum alloy casting coating is mainly used for high-grade products such as large vehicles, train cars, locomotive heads, yachts, ships, docks, bridges, machine tools, instruments and meters, grain machinery, steel structures or aluminum alloy surfaces for high-performance finishing Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
