We use fire retardant coatings in home decoration, but there are many different kinds of fire retardant coatings on the market, such as oily, water-based, steel structure and other fire retardant coatings. Waterborne fireproof paint is along with the fireproof coating application field unceasing expansion and the environmental protection law unceasing improvement but appears. With its green, health, environmental protection and other environmental protection functions become the general trend of industry development. Because of its excellent environmental protection, construction safety and fire resistance, water-based expansive fireproof coating is gradually favored by many owners and designers. At present, there are more than 100 water-based fireproof paint manufacturers in China, with tens of thousands of tons of output and dozens of varieties.
Now let's know what are the advantages and disadvantages of waterborne fireproof paint and kinds of introduction!
1. Water-based fire retardant paint with water as the solvent, saving daxing resources. Eliminate fire hazards in the construction process; Reducing pollution of the atmosphere; Only a small amount of low toxic alcohol ether organic solvent can be used to improve the working environment, reduce pollution and save resources.
2. Can be directly applied to the manufacture of wet surface environment; Ice coating has strong adhesion and good adaptability to material surface.
3. Paint tools used for water-based fireproof paint construction can be cleaned with water, thus reducing the consumption of cleaning solvents. Good flattening and other characteristics. In the cavity, weld, edge, edge and other parts.
4. Electrophoretic coating can be uniform and smooth, good protection. That is, the corrosion resistance of electrophoretic coating, the salt spray resistance of thick film cathodic electrophoretic coating can reach 1200 hours.
5. High requirements on the cleanliness of the construction process and material surface. The film shrinks due to the high surface tension of water.
6. Poor dispersion stability for strong mechanical forces. When the flow rate in the pipe changes rapidly, the dispersed particles are compressed into solid particles, which will produce pitting on the coating film. Therefore, it is required that the shape of the conveying pipe is good and the pipe wall is free from defects.
7. It is highly corrosive to the coating equipment, so it needs anti-corrosion lining or stainless steel materials, and the equipment cost is also very high. Water-based coatings corrode pipes, dissolve metals, precipitate dispersed particles, and produce pitting on the coating. The building also needed stainless steel pipes.
Advantages and disadvantages of waterborne fireproof paint and types
1. Water-based paint: this kind of water-based paint contains water-soluble resin and other types of resin raw materials, coated on the wall can form a film layer to protect the wall. The appearance of waterborne fireproof paint is called "the third paint revolution" by the industry because of its environmental performance.
2. Water dilution coating: mainly contains emulsion emulsion dissolved resin, directly add water dilution during construction, to achieve the construction effect.
3. Water dispersion coating: the main principle is to form emulsion on the basis of synthetic resin, that is, latex coating.
Do you have a basic understanding of the advantages and disadvantages and types of waterborne fireproof paint through the above introduction?
