Jinan composite board is added cement plaster on the basis of rock wool board, which shortens the construction period of rock wool board by 70% and improves the project progress. It has the advantages of light weight, small thermal conductivity, heat absorption and non combustion. It is deeply loved by consumers in the market. How much do you know about it? Do you know how to use it? Next, Jinan composite plate manufacturers will be in the following for you a brief introduction, I hope to help you.
Jinan composite plate
Rock wool composite board is mainly used for building thermal insulation, including wall insulation, roof insulation, door insulation and ground insulation. Among them, the wall insulation is the main, which can adopt two forms of composite wall on site and prefabricated composite wall in factory. One of the former is the inner insulation of the outer wall, that is, the outer layer adopts brick wall, reinforced concrete wall, glass curtain wall or metal plate, the middle layer is air layer and rock wool layer, and the inner surface is paper faced gypsum board. The other is external thermal insulation of external wall, that is, the rock wool layer is pasted on the outer layer of the building, and then the external decoration layer is added. Its advantage is that the use area of the building is not affected.
When using rock wool composite board, the influence of environment should be considered. At first, rock wool composite board was used in wood structure. Because of poor weather resistance, easy aging and peeling, reliability of expansion in humid and corrosive environment, as well as dense smoke and toxic gas generated by resin decomposition during high-temperature fire barbecue and foaming process, there are no special measures In tunnels, outdoors and buildings where people often stay, it is not suitable to use expansion type a fireproof rock wool composite board. The projects in nuclear power, electric power, petrochemical and chemical industries should be mainly made of thick class a fireproof rock wool composite board.

In addition, the use of rock wool composite board in different buildings should be strictly controlled, especially the application of steel columns, steel beams, steel floors and steel evacuation stairs in large-scale public and civil buildings. Steel column, steel floor, steel evacuation stairs and other major building components should give priority to the use of steel mesh concrete and other fire protection materials. If there are difficulties, the thick steel structure A-class fireproof rock wool composite plate can be used for protection, the thin steel structure A-class fireproof rock wool composite board should be carefully selected, and the selection of ultra-thin steel structure A-class fire-proof rock wool composite board should be strictly controlled. In high-rise building steel structure and multi-storey steel structure workshop, it is not suitable to use thin and ultra-thin steel structure grade a fireproof rock wool composite board.
The above is Jinan composite board manufacturers in the following for you to introduce the use of rock wool composite board, I believe you have a further understanding of the composite board, hope the above content can help you, more details, please pay more attention to our website http://www.jnjgcg.com You are welcome to visit and purchase at any time.
