Coating general knowledge: waterproof coating is classified according to raw material powder

Core tips: prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquid and air moisture, steam and other materials from invading buildings The main parts of the building that need to be waterproof are the roof, wall, ground and basement There are many kinds of waterproof materials, which can be divided into four categories according to their main raw materials: ① Asphalt waterproof materials With natural asphalt, petroleum asphalt and coal asphalt as the main raw materials, the asphalt felt, paper-based asphalt felt, solvent type and water emulsion type asphalt or asphalt rubber type coating and ointment are made, which have good adhesion, plasticity, water resistance, corrosion resistance and durability Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: to prevent rainwater, groundwater, industrial and civil water supply and drainage, corrosive liquid and air moisture, steam and other materials from entering the building The main parts of the building that need to be waterproof are the roof, wall, ground and basement There are many kinds of waterproof materials, which can be divided into four categories according to their main raw materials: ① asphalt waterproof materials With natural asphalt, petroleum asphalt and coal asphalt as the main raw materials, the asphalt felt, paper-based asphalt felt, solvent type and water emulsion type asphalt or asphalt rubber type coating and ointment are made, which have good adhesion, plasticity, water resistance, corrosion resistance and durability ② Rubber plastic waterproof materials With neoprene, butyl rubber, EPDM, PVC, polyisobutylene, polyurethane and other raw materials, it can be made into elastic tire free waterproof roll, waterproof film, waterproof coating and film Materials and sealing materials such as ointment, mastic, waterstop, etc have the characteristics of high tensile strength, high elasticity and elongation, good adhesion, water resistance and weather resistance, which can be cold used with long service life ③ Cement waterproof materials The admixtures, such as water-proof agent, air entraining agent and expansion agent, can enhance the hydrophobicity and impermeability of cement mortar and concrete, and the cement and sodium silicate as the base material can be used for plugging and waterproofing of underground engineering ④ Metal waterproof materials Steel sheet, galvanized steel sheet, profiled steel sheet, coated steel sheet, etc can be directly used as roof slab to prevent water Sheet steel is used for metal waterproof layer of basement or underground structure Thin copper plate, thin aluminum plate and stainless steel plate can be made into waterstop of building deformation joint The joint of metal waterproof layer shall be welded and painted with antirust protective paint 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,
