Building environmental protection grade A fire insulation board main production methods and materials

Building environmental protection grade A fire insulation board mainly there are two kinds of production methods, namely, physical foaming and chemical foaming. Both production methods using the characteristics of the cement to coagulate. A-class fire insulation board performance is stable, very popular. Class A fire insulation board is the most ideal material of wall insulation fire.

Building environmental protection grade A fireproof insulation board main fireproof heat insulation. The material has good fireproof performance, cement will not burn, it is common sense, and A grade fire insulation board under the high temperature baking can still maintain strong combination, won't appear crack. Many places in the construction industry for fireproof performance requirements is high, the foamed cement insulation board is essential for the construction industry, and its heat insulation performance is very good. It also has a seismic performance, the product through the country of the actual test, although the quality is small, but the performance is very strong. Sound insulation for class A fire insulation board is also A feature, have the product don't have to buy separate sound insulation materials. The sound insulation effect of the material is five times higher than normal concrete qualitative effect. A-class fire insulation board is A kind of environmentally friendly products, non-toxic, not only itself can be recycled, save costs further. Class A fire insulation board service life is long, not like A normal material device, often should change. Convenient construction, short construction period is also a feature of the material products.

Building environmental protection grade A fire insulation board:

1, 42.5 ordinary Portland cement to fast setting, rapid hardening Portland cement can be used or sulphur aluminate cement;

2, first class or second class fly ash and slag powder such as active admixture;

3, foaming agent. When using rapid hardening Portland cement or sulphur aluminate cement, all kinds of foaming agent are used;

4, ordinary Portland cement coagulant. Mainly improve the ordinary Portland cement setting speed, reduce the bubble;

5, resistance to water absorption, enhance products mainly of water flood resistance, lower water absorption.
