Color steel plate material composition Material composition
(1) Color steel plate surface material metal panel such as color coated steel plate, aluminum alloy plate, etc. Color coated steel frame
(2) Core material of color steel plate According to the chemical composition of the material, the core material can be divided into two categories: one is organic foam materials, such as polyurethane styrene foam plastics, urea-formaldehyde foam cyanamide foam plastics, etc. The other type is material, such as rock wool board,
(3) Color steel plate connection material The most commonly used connection material is keel, followed by steel wire.
(4) Color steel plate consolidation materials
One is screws. According to the performance and usage method, screws can be divided into steel nails, shot nails, self-tapping screws, self-drilling self-tapping screws, metal expansion bolts, plastic expansion bolts, core strike aluminum rivets and so on.
The second is adhesives. According to the composition of adhesives, it can be divided into organic adhesives, urea resin adhesives,
Melamine formaldehyde resin adhesive, one-component polyurethane adhesive, two-component polyurethane adhesive, etc. Commonly used inorganic adhesives include cement, gypsum, water glass, etc. Commonly used organic-inorganic composite adhesives include polyvinyl alcohol-a gypsum adhesive, polyvinyl alcohol B gypsum adhesive, water glass slag adhesive, and polyvinyl acetate cement adhesive. Classification and technology of color steel sandwich composite board
Fourth, the classification and process of color steel sandwich composite board Color steel sandwich composite board is currently used more types: color steel polyurethane composite board, color steel polystyrene composite foam plastic, polymer, phenolic foam plastic, Three types of materials, straw board inorganic fiber material glass wool board, etc. Color steel rock wool composite board.
PPGI / PPGL COIL full name is prepainted galvanized / galvalume steel coil, which is painted lacquer on top and bottom side of HDGI / ALU-ZINC coil. They are mostly used for construction with various paint colors, like warehouse, prefab house, and garage, etc.
The advantages of PPGI / PPGL are light weight than traditional brick wall, high-strength, heat-insulation, colorful, and easy installation.
