Rock wool is recognized as one of the best thermal insulation materials in the world

Due to the application of organic materials in building energy-saving projects, fire accidents caused by external wall insulation materials continue to occur everywhere, causing great losses to people and national properties. The occurrence of these fires, without exception, is related to insulation materials. So, are there any building materials that are not only heat preservation, energy saving, but also fireproof and waterproof?

Rock wool thermal insulation and fire prevention

Major fire accidents are all related to building exterior wall insulation materials, so the fire protection of insulation materials has once again attracted people's attention. At present, the materials used in building exterior wall insulation include silicate insulation materials, rubber powder polystyrene particles, steel mesh foam boards, etc. The fire protection and environmental protection performance is not ideal.

Rock wool stands out for its many advantages such as heat preservation, heat insulation, fire protection and sound absorption, and has become the darling of the heat preservation material market.

Rock wool is a natural environment-friendly fireproof, heat-insulating insulation material. Rock wool is made of natural rock, etc. as the main raw material, plus a certain amount of auxiliary materials, which are melted and sprayed at high temperature to make artificial fiber, and then make it into rock wool products. The outer wall heat preservation, fire prevention and heat insulation use a lot of rock wool . The production of rock wool insulation materials and their application in building energy conservation strive to greatly reduce energy consumption, thereby reducing environmental pollution and the greenhouse effect. At present, the application of rock wool thermal insulation materials on the exterior walls of buildings is relatively mature, and thermal insulation materials for building energy conservation account for the vast majority. For example, in the United States, Sweden, Finland and other countries more than 80 rock wool is used for building thermal insulation and energy saving; in Germany, the law clearly stipulates that the use of organic combustible thermal insulation materials (such as polystyrene materials) is strictly prohibited for buildings with a height of more than 22 meters. , Most of them use rock wool as insulation and sound insulation for internal walls, external walls and roof insulation. At present, rock wool has dominated the thermal insulation material market because of its good heat preservation, heat insulation, fire prevention, sound absorption characteristics, and environmental protection, economy, and practical advantages, and is recognized as an ideal thermal insulation material at home and abroad.

Rock wool is the most ideal insulation material for building exterior walls and roofs

At present, many people still look at rock wool with old eyes, believing that rock wool has high water absorption, low strength, uncomfortable construction process, etc. These are all rock wool produced by the sedimentation method 20 years ago. After these years of development, rock wool production technology has undergone earth-shaking changes. The high-performance rock wool insulation board is made of selected natural basalt as the main raw material. After high temperature melting, it is fiberized by an internationally advanced high-speed four-roll centrifuge, and the basalt high-temperature solution is drawn into 4-7μm discontinuous fibers. A certain amount of binder, dust-proof oil, and water-repellent agent are collected by drum cotton collecting machine, cotton spreading with pendulum, pleating, pressing, curing, cutting and other processes to make rock wool of different bulk density and specifications for construction board.
