Fireproof board is a kind of material often used in decoration. This material has very practical and special physical properties, and the decoration is also very good. There are many kinds of fireproof boards in circulation on the market. Different fireproof boards have corresponding advantages. Only after fully understanding the characteristics of fireproof boards can we use them better.
Fireproof board is a kind of refractory building material for surface decoration, which is widely used in interior decoration, furniture, kitchen cabinet, laboratory table, exterior wall and other fields. Fireproof board is made of base paper (titanium powder paper, kraft paper) through melamine and phenolic resin impregnation process, through high temperature and high pressure environment.
Mineral wool board, glass wool board: mainly mineral wool, glass wool as insulation materials. It is nonflammable, high temperature resistant and light in weight, but its disadvantages are as follows: ① short fiber will cause harm to human respiratory system; ② poor strength of plate; ③ poor barrier performance of plate to fire smoke spread; ④ poor decoration; ⑤ heavy installation and construction workload. Therefore, most of the boards have evolved into inorganic bonding materials as the base material, mineral wool, glass wool as reinforcement materials.
Cement board: cement board has high strength and wide sources. In the past, it was often used as fireproof ceiling and partition wall, but its fire resistance performance was poor, and its application was limited because it was easy to burst and perforation in the fire and lost its protective effect. The cement concrete component has good performance of heat insulation and sound insulation, and can be used as partition wall and roof panel. Fiber reinforced cement board and other improved varieties have appeared in the building materials market, which has the advantages of high strength and good fire resistance, but poor toughness, high alkalinity and poor decorative effect.
Perlite board, floating bead board, vermiculite board: it is a hollow board made of low alkalinity cement as the base material, perlite, glass beads, vermiculite as the aerated filling material, and some additives. It has the characteristics of light weight, high strength, good toughness, fire prevention and heat insulation, convenient construction, etc. it can be widely used in non load bearing parts of high-rise frame buildings, such as rooms, households, toilets, kitchens, communication pipes, etc.
Fireproof gypsum board: since the fireproof performance of gypsum is widely accepted, the fireproof board based on gypsum develops rapidly. The main component of the board is nonflammable and contains crystal water, which has good fire resistance and can be used as partition wall, ceiling and roof panel. The raw material source of the plate is rich, and it is convenient for the factory to produce. In use, it has light weight, can reduce the building load-bearing, and easy processing, can be sawed and planed, convenient construction, good decoration, but its bending resistance is poor. There are many factors affecting the performance, such as the thickness of the keel board, the composition of the filler, the composition of the air, etc.
In recent years, new varieties such as calcium silicate gypsum fiberboard, double-sided sticker gypsum fireproof board have appeared.
Calcium silicate fiberboard: it is a building board with lime, silicate and inorganic fiber reinforced materials as the main raw materials. It has the characteristics of light weight, high strength, heat insulation, good durability, excellent processing performance and construction performance. It is mainly used for making ceiling, partition wall and fire protection materials for steel columns and beams. However, the strength and bending properties of the sheet still need to be improved.
