Class a fireproof insulation board belongs to fireproof and thermal insulation material with fire protection grade a. Class a insulation material is mainly A1 and A2 grade materials. Class a materials include A1: monomer inorganic non combustible; A2: composite organic non combustible, that is, composite materials. A3 grade: modified phenolic fireproof material.
Class A is non-combustible material: WW inorganic active wall insulation material, cement foamed insulation board, glass bead insulation mortar, rock wool board, glass wool board, etc. Class A is non combustible material with the characteristics of low density, low thermal conductivity, high bearing capacity, convenient construction, and economy and durability.
A fire insulation board is widely used as insulation, insulation and sound absorbing materials for heat insulation and insulation materials of heat pipes, heat equipment and other industrial pipes and industrial buildings. Because of its good thermal stability, it can be used as a fire protection coating material for steel structures.
Performance comparison of a fire prevention and insulation board
Rock wool board, phenolic board, foamed cement, foamed glass, foamed glass, new EPS insulation board can all achieve the effect of a grade a fire retardant, but the fireproof effect of the rock wool board is the best, but the rock wool board is very easy to destroy the coating and ceramic tile, and the material is soft, the bearing capacity is poor, and the price has no advantage, there is no advantage in price. So, rock wool board has not been favored by the construction industry.
The thermal conductivity of the phenolic aldehyde plate is small, and the effect of insulation and energy saving is good, but the surface layer is easy to remove powder, difficult to paste, low strength, high hidden danger and high price, which is not conducive to popularization.
The foamed cement/foamed glass is brittle, difficult to anchor, difficult to control the insulation effect, new construction technology and high labor cost.
The new EPS fireproofing and insulation board has a certain toughness, high strength, small bulk density, and can paste ceramic tiles. The technology is mature, the construction is convenient, the artificial cost is low, the heat preservation effect is good, the quality is easily controlled, and the price is reasonable, lower than the phenolic board.
