Clicks: 【451】 Date: [2017/2/20 15:39:53]

Henan thermal insulation material manufacturer reminds you that rock wool board manufacturers inflated A-grade fire-resistant rock wool boards were first used for wooden structures. Due to poor outdoor weather resistance, easy aging, peeling, and reliability problems of expansion in humid and corrosive environments In addition, in the process of high-temperature flame barbecue foaming, the resin decomposes to produce dense smoke and toxic gases. Therefore, without special measures, it is not suitable to use expanded A-grade fireproof rock wool boards in tunnels, outdoors, and buildings where people often stay. Nuclear power, electric power, petrochemical and chemical industries should mainly use thick A-grade fire-resistant rock wool boards.

It is necessary to strictly control the construction of all-steel structures, especially the use of steel columns, steel beams, steel floor slabs and steel evacuation stairs in large public civil buildings. Steel pillars, steel floor slabs, steel evacuation stairs and other major building components should be preferred to use steel wire mesh concrete and other fire protection materials. If it is really difficult, you can choose thick steel structure A grade fireproof rock wool board protection, carefully choose thin steel structure A Grade fire-resistant rock wool board, strictly control the selection of ultra-thin steel structure A grade fire-resistant rock wool board. For high-rise building steel structures and multi-story steel structure workshops, it is not suitable to use thin-coated and ultra-thin steel structures of Class A fireproof rock wool board.
