In March 14, 2011, the Ministry of public security fire department issued the "Circular on further clarifying the relevant requirements of fire supervision and management of civil construction exterior insulation materials" (public consumption [2011]65), requirements of civil building exterior wall thermal insulation material should be used in combustion properties of a material, namely incombustible materials. The introduction of this document is undoubtedly a great positive news for the Shandong round friends group, who has fireproof, environmental protection and energy saving functions.

 

In recent years, due to the material cause of domestic building insulation wall of flammable fire often found in newspapers, such as the Nanjing Central International Plaza, new CCTV affiliated cultural center in Shanghai, Jiaozhou, Shenyang Royal Wan Xin teachers apartment building, causing serious casualties and property losses. Building flammable and combustible external thermal insulation material has become a new kind of fire hazard, and the fire caused by this has shown a lot of situation.

 

Yuanyou group chief engineer Liu Weihua through many years of research, development of electric heating pipe vitrification furnace light mortar production equipment with independent intellectual property rights, the device produces a new material of expanded and vitrified beads from the pitchstone ore, to replace the traditional heavy aggregate mortar, such as sand and other granular material. The dry powder mortar produced by expanded vitrified microbeads has excellent properties such as environmental protection, energy saving, wood saving, fire protection and so on. It is very popular in the building market. Such materials are used as building materials for external wall insulation, such as the national environmental building and the expansion project of the capital airport.
