In recent years, there have been a number of incidents involving building insulation fires that have led to reflections on insulation and fire prevention. The unprecedented fire protection performance of insulation materials has attracted great attention from all walks of life in the industry. However, many fire protection materials are generated during the construction process, such as: welding, open flames, poor construction practices. The melting drips and poisonous smoke that these materials continue to produce during the combustion process, and the harm to the environment caused by the gases such as chlorofluorocarbons, hydrofluorocarbons and freon released at the same time cannot be ignored. Next, Xiao Bian introduced to everyone the characteristics of fire insulation materials and fire insulation materials. What are the fire insulation materials 1, foamed silicate material This material is mainly made of cement and some pulverized coal, as well as other cementitious materials, etc. It has been processed and manufactured, and it has good high temperature resistance, aging resistance and fire resistance. 2. Autoclaved aerated concrete This kind of fireproof and heat preservation material is made of cement or lime, and some sand, etc. are added into the aluminum powder and then mixed with water, formed, expanded, cut and cured. 3, poly light high alumina brick This kind of material has high porosity, so the heat insulation and high temperature resistance are very good. The more used ones are some masonry industries that need insulation or insulation. Therefore, this material can reduce the weight of the furnace. , can shorten the furnace, but also to maintain the furnace temperature is uniform. 4, rubber sponge insulation material This material is relatively soft, with good cold resistance, heat resistance and fire-retardant, waterproof performance, use more is the construction, pharmaceutical and some vehicle electrical industries, not only can reduce the cold loss and heat loss Role, but also to meet the needs of various locations. Fire insulation material characteristics 1. Rock wool is also called rock wool in our life. It is a kind of fluffy short fiber made of natural rock, mineral or industrial waste. It has high tensile strength, fire resistance, chemical resistance, thermal insulation, electricity. Insulation and other characteristics; 2. Mineral wool is a type of metallurgical slag in the molten state that is formed into a flocculent shape by means of injection or centrifugation, and is characterized by heat insulation, sound absorption, corrosion resistance, and non-combustibility. 3. Glass wool is a type of glass fiber that will be melted to form a fluffy cotton-like material, with good shape, small bulk density, low thermal conductivity, thermal insulation, good sound absorption, corrosion resistance, and stable chemical properties; 4. The expanded perlite is well accepted by the market and exerts its effects with its good thermal insulation performance, and it has a wide range of application and universal practicality, especially in the fire-resistant insulation and energy-saving performance. ; 5. Foam glass is an inorganic non-metallic glass material made of cullet, foaming agent, modifying additive and foaming accelerator, etc., after finely comminuted and uniformly mixed, then subjected to high temperature melting, foaming and annealing. With moisture, fire, anti-corrosion effect. 6, YT inorganic thermal insulation material insulation effect is good, with water resistance, crack resistance, anti-air drums, and buildings with the same life advantages. The product is suitable for all kinds of grass-roots walls. The construction is simple. After mixing with water, it can be painted on the wall. It saves time and labor and meets the national 65-75% energy-saving requirement. Fire insulation material grade 1ã€Class A insulation material Rock wool, mineral rock wool, glass wool, foam glass, foam ceramic, foam cement, inorganic thermal insulation mortar, etc. 2. Fire insulation grade B1 insulation material Extruded polystyrene board (XPS), polyurethane (PU), thermoset modified polyphenylene (TPS), phenolic, powdered polystyrene, etc. 3, fire protection grade B2 insulation materials Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE) and so on. Editor's summary: What are the characteristics of fire insulation materials and fire insulation materials introduced here, and hope to be helpful to everyone.
