Thermal insulation material fire treatment and how to buy

At present, there is a concept that most of the fires in the construction of the existing external wall insulation materials are caused by the fire on the construction site, while there are few fire cases in the external insulation construction project in use. The fire safety of external insulation can be ensured by dealing with the fire danger during the construction period.

In the domestic existing external insulation project fire, most of the attack in the construction process, the external insulation building use in the process of fire cases is relatively small. The reason is that the organic insulation board is bare in the construction process without any protective layer. The construction process is often interspersed with hot work, which is easy to cause fire. However, few people realize that the external insulation system with poor fire resistance plays a promoting role in the fire when the fire breaks out in the construction.

At present, Class A fireproof insulation materials include rock wool board, foam glass board, glass wool board, microporous calcium silicate, expanded perlite products, vitrified microsphere products, expanded vermiculite products, aerated concrete board and block, lightweight aggregate foamed concrete insulation board and block, various inorganic insulation powder, inorganic insulation slurry and its products, etc. From the civil construction of external insulation engineering fire protection skills.

External wall insulation should be building science, information science, fire science and environmental protection science of the four disciplines organically combined. Any research contrary to the four disciplines have relative one-sidedness and limitations. Do a good job of external wall insulation fire protection needs to do the following:

1, strict implementation of various fire regulations and fire standards;

2. Select good insulation materials;

3, the use of insulation materials during the primary fire prevention measures;

4, the use of insulation data during the intermediate construction process monitoring, to prevent all kinds of fire can;

5, after the insulation materials are made into the external wall insulation system, the correct use of the insulation system and the prevention of fire.

The purchase of this exterior wall insulation information should usually pay attention to the following points:

1. Check the appearance of the goods. The demand is less damaged, the color is the same, and the scale is accurate (length and width tolerance 4mm, thickness tolerance 2mm.

2. Measure commodity density. Choose a piece of products, say its component, measure its volume, you can calculate the density, under the premise of satisfactory strength requirements, the smaller the density, the better.

3, simple measurement strength. The strength demand of thermal insulation products is mainly the demand for satisfactory transfer, which is usually not high, which is 1/10-1/20 of the strength of red brick, but it cannot be broken when touched and scattered when pinched. According to the specification requirements, the compressive strength is usually above 0 and 5MPa, that is, the product should be able to accept a person standing quietly on it (the area of the product should be larger than the area of the foot,.

4, inspection of commodity skills documents and quality inspection report. Standard goods should have skills, quality inspection, qualification certification and other relevant certificates.
