Classification and development trend of commonly used fire and heat preservation materials
In order to ensure safety, the Ministry of Residence Construction and the Ministry of Public Security issued the Interim Provisions on Fire Protection of External Insulation Wall Decoration for Civil Construction in September 2009. In the provisional provisions, the incineration function of adiabatic materials used in residential buildings with height greater than or equal to 100m, general construction with height greater than or equal to 50m and curtain wall construction with height greater than or equal to or equal to 24m shall be Class A.
Class A refers to non-flammable materials, but at present, the most commonly used materials for building external thermal insulation in China are organic materials. Even with the addition of flame retardants, the maximum can only reach B1. If we want to strictly implement the most stringent fire order in history, it means that our insulation profession will face the whole shuffle, and even shielding situation. Therefore, Guiyang Fire-proof and Thermal Insulation Materials for Exterior Wall has a considerable market capacity, which can bring greater business opportunities for companies engaged in the production of exterior wall thermal insulation materials.
Fire and heat preservation data
Currently, about 50% of the energy is lost on walls, 10% on roofs, 25% on doors and windows, and 15% on basements and floors. How to select a kind of wall thermal insulation construction material which is both safe and environmentally friendly is the key to the construction of energy-saving thermal insulation construction materials in China.
Commonly used insulation inion is as follows:
1. rock wool and glass wool are sometimes referred to as mineral cotton, and they are all attributed to inorganic materials. Its fireproof function is good, durability is good, can complete synchronization with the structure life, low price, not only can satisfy the thermal insulation function, together with a certain sound insulation function, can improve the working conditions of workers.
2. Polystyrene foam sheet is a kind of material with numerous closed micropore, which is made of polystyrene resin as the main raw material and foamed by foaming agent of insulating material manufacturer. It has excellent insulation function, and its thermal conductivity is lower than other data.
3. polystyrene particle insulation slurry consists of polystyrene particles and insulating rubber powder. The data structure is simple and the insulation function is good. Polyphenylene particles can be used not only as industrial products, but also as particles after mechanical breakage of waste polystyrene insulation panels, which is very useful for avoiding white pollution and protecting the environment.
In summary, all the above-mentioned materials provided by Shandong Guangri Building Materials Co., Ltd. would like to know more about A1 class fire and thermal insulation materials. Welcome to pay attention to our website: . Thank you for your support!
