Problems solved by technology

Generally, organic thermal insulation materials can only reach B1 and B2 standards at most, and cannot meet the needs of fire protection. Recently, the Shandong Provincial Department of Housing and Urban-Rural Development and the Shandong Provincial Bureau of Quality and Technical Supervision jointly issued the "Residential Building Design Standards" (DB37 / 5026- 2014), "Design Standards for Residential Buildings" (DB37 / 5026-2014) will be implemented on October 1. This standard requires the full implementation of 75% energy-saving standards for residential buildings, and the new version of the national standard "Code for Fire Protection Design of Buildings" (GB50016-2014) It is required that the fireproof layer of the thermal insulation material reaches 50mm, but the energy-saving standard of the existing thermal insulation materials is mostly 65%, and the fireproof index can only reach the B1 and B2 level standards, and the fireproof layer is less than 5 cm. Therefore, an energy-saving standard of 75%, non-combustible Class A insulation materials urgently need to appear
