Aluminum silver paste

Product Name: aluminum paste English Name: aluminum paste alias: aluminum powder paste; flash paste; silver paste aluminum silver paste product, is an indispensable metal pigment Its main components are flake like aluminum particles and petroleum solvents, which are paste like It is characterized by smooth and flat surface, concentrated particle size distribution, regular shape, excellent light reflection ability and metallic luster It is mixed with transparent color pigments The paint film has obvious "color effect with angle", and the decoration effect is very gorgeous and beautiful Mainly used in automobile coating, weak current plastic coating, metal industrial coating, ship coating, heat-resistant coating, roof coating, etc In the past two or three years, our country's aluminum silver paste products have begun to use micro spherical aluminum powder as raw materials We have made great breakthroughs in technology, but the performance index, coating effect and other aspects of its products can not reach the level of similar products abroad Aluminum silver paste is a kind of pigment It is made by special processing technology and surface treatment to make the surface of aluminum sheet smooth, flat, neat edge, regular shape, concentrated particle size distribution, and good matching with the coating system Aluminum silver paste can be divided into two types: floating type and non floating type In the grinding process, one kind of fatty acid is replaced by another, which makes the aluminum silver paste have completely different characteristics and appearance The shape of aluminum sheet has snowflake shape, fish scale shape and silver element shape In the floating aluminum silver paste, the aluminum sheets are oriented near the surface of the paint film to form an opaque silver film, which is the main factor that makes the floating aluminum silver paste become an important functional raw material Floating aluminum silver paste is mainly used in roof coating, maintenance and commercial application with high protection requirements The appearance of the floating aluminum silver paste can vary according to the thickness of the particles, from the rough and white appearance to the gray, highly reflective or mirror like effect The coarse-grained floating aluminum silver slurry has the lowest covering power and rough structure, but it can obtain the whitest and brightest coating On the contrary, the fine-grained floating aluminum silver slurry has the largest covering power, the smoothest structure and the coating with high reflective force The non floating aluminum silver paste is evenly distributed in the whole paint film The appearance of the film is different from that of the floating aluminum silver paste Because it can be mixed with a variety of pigments and can be applied to a variety of systems, it has a unique effect on industrial coating However, any pigment or dye used with non floating aluminum silver paste must be transparent, so as to achieve the effect of realistic metal surface There are many kinds of non floating aluminum silver paste, the coloring power is from low to high, the particle size is from coarse to fine, the appearance is from white, shiny to gray, more delicate, and acid resistant series products, reducing the impact of industrial smoke, acid rain and other adverse environment on the coating Aluminum silver paste is not easy to ignite and explode Covering power, brightness, triggering performance, metal performance and smoothness are the technical requirements for identification of aluminum silver paste The model of aluminum silver paste is classified according to the size of particles Application: widely used in plastic paint, hardware appliance paint, motorcycle paint, bicycle paint and so on According to the list of dangerous chemicals, aluminum silver paste belongs to 33646 categories: paint, auxiliary materials and coatings containing secondary flammable solvents However, due to the requirements of environmental protection and safety of chemical products at home and abroad in recent years, domestic manufacturers have changed their processes one after another, instead of using secondary flammable solvents as carriers, they choose safe and environmental protection solvents with higher flash point At present, the aluminum silver paste produced is no longer in the scope of dangerous goods in the actual chemical properties
