the sheet

[qizhen111]

<p>This kind of sheet has good high temperature resistance, light texture, but poor strength, and short fiber will cause respiratory damage to the human body. Cement board cement board has high strength, but its fire resistance is relatively poor. It is easy to burst perforation and lose its protective effect in the fire field, which limits its application. Perlite plate, floating bead plate and slate plate have the characteristics of high strength, good toughness, fireproof and heat insulation, and convenient construction.</p><p> These plates are mainly used for non-load-bearing parts such as bathrooms, kitchens, and communication pipes.Fire-retardant and flame-retardant: Concrete is inorganic, does not burn, does not produce harmful gases at high temperatures; in addition, the concrete has a small thermal conductivity, which makes the heat migration slow, can effectively resist fire and protect the structure from fire. Sound-absorbing sound insulation: good sound insulation and sound absorption. Good durability: good durability, no aging problems, long service life. Green and environmental protection: no radioactive substances and harmful gases are generated during use. </p>
