What are the types of external wall fire insulation board equipment?
There are many types of fireproof insulation board equipment for exterior walls, and each variety has its own characteristics, making it difficult for consumers to choose. The following editor will introduce to us phenolic foam exterior wall fire barrier belts, exterior wall plastered rock wool boards, and basalt wool insulation boards. Fireproof rock wool board, cement foam fireproof insulation board, polyurethane composite fireproof insulation board.
1. Phenolic foam external wall fire barrier belt, excellent fire performance: organic insulation materials such as polyurethane and polystyrene, after burning, will produce dense smoke and poisonous, which will easily cause death and increase the difficulty of rescue. The phenolic insulation board is non-combustible in case of fire, and its combustion performance is as high as Class A. The maximum operating temperature is 180°C (allowing instantaneous 250°C), and the flame resistance of 100mm thick phenolic foam can reach more than 1 hour without being penetrated. Under the direct action of the flame, it has carbon formation, no dripping, no bending, and no melting phenomenon. After the flame burns, a layer of “graphite foam” is formed on the surface to effectively protect the foam structure in the layer; excellent thermal insulation function: thermal conductivity Low (<0.025W/m×K, more than twice that of polystyrene, similar to polyurethane), excellent material for heat preservation and heat insulation; anti-corrosion and anti-aging: almost resistant to all inorganic acids, organic acids, and organic solvents corrosion. Exposure to sunlight for a long time without significant aging phenomenon, so it has good aging resistance; low density and light weight: the density of phenolic insulation board is below 100㎏/m3, and can reach about 50㎏/m3. It can reduce the self-weight of the building, reduce the load of the building, reduce the structural cost, and the construction is simple and convenient, and can improve work efficiency; sound absorption performance: phenolic insulation board has excellent sound absorption performance, and the open-cell foam structure is more Good for sound absorption; environmental protection: rock wool and glass wool are harmful to the environment and people, and polyurethane and polystyrene will decompose and produce highly toxic gases such as hydrogen cyanide and carbon monoxide when incinerated and heated. The phenolic insulation board adopts fluorine-free foaming technology and no fiber, which meets the environmental protection requirements of the country and the world.
2. External wall plastering rock wool board Basalt wool insulation board Fireproof rock wool board, with basalt and dolomite as the main raw materials, through high-temperature melting, centrifugal blowing, and pendulum method to make boards. It has the characteristics of non-flammable, non-toxic, low thermal conductivity, hydrophobic, sound absorption, stable physical and chemical properties, etc. Combined with its strong vertical tensile strength, it is connected and fixed with the base wall by the combination of sticking and nailing. The plastering mortar and glass fiber mesh cloth for reinforcement are combined to form a protective layer, and finally the decorative mortar or paint is used as the protective layer. The exterior finish constitutes a stable external wall insulation system. Rock wool board is made of natural ore as the main raw material, which is melted into fibers at high temperature, added with an appropriate amount of binder, and solidified. It is widely used in ships, metallurgy, electric power, construction and other industries. It has excellent heat insulation and sound insulation effects. . The construction and installation are convenient, the energy saving effect is remarkable, and it has a high performance-price ratio. Marine rock wool boards are used for thermal insulation and fire protection of ships; rock wool boards are used for vehicles, mobile equipment, cold storage projects, air conditioning pipes, thermal insulation and fire protection in humid environments, and applications that have certain requirements for moisture resistance. Rock wool board for construction has excellent fire prevention, heat preservation and sound absorption performance. It is mainly used for thermal insulation and sound insulation of building walls and roofs; for fire prevention and noise reduction of building partition walls, firewalls, fire doors and elevator shafts. Good heat insulation and noise prevention functions; the product has flame retardancy; high temperature resistance; low chlorine content; light weight, easy loading and unloading; low cost, high cost performance; no maintenance; convenient installation, etc.
3. The cement foam fireproof insulation board is a grade A non-combustible inorganic heat preservation material, which has excellent fireproof performance. It can still maintain integrity after being baked at 1200 degrees for 3 hours. It can be used in buildings to improve the fireproof performance of buildings. Because of its closed cell rate > 95%, it has a good heat insulation function. Lightweight and shock resistance, the product has light bulk density, dry volume, and a density of about 250kg/cubic. The plate has passed the 1.5 million anti-fatigue vibration tests of the National Testing Center. The plate and the steel structure are welded as a whole, which can withstand earthquakes of magnitude 9. . It is composed of many porous independent air cells, so the sound absorption effect is about 5 times higher than that of ordinary concrete, and the sound insulation coefficient is greater than 45dB. The construction is convenient, the construction period is short, no sand, cement and other materials are required during construction, the materials are stacked simply, efficiently, and small in size, occupying less resources such as site equipment, no construction waste, and no plastering after construction. The traditional block wall requires 12 people and 60 minutes of construction, and the foam cement board only needs 3 people and 60 minutes to complete, saving labor costs. Compressive strength, strong adhesion. The foamed cement board uses mercury-mixed fiber to add the compressive strength of the foamed cement board. According to the inspection of the national professional testing organization, the bending damage load is more than 3 times of its own weight (the national standard is 1.5 times), and the compressive strength The hanging force is above 5/Mpa (the national standard is 3.5/Mpa), and the hanging force is above 1500/N (the national standard is 1000/N). Non-toxic, harmless, environmentally friendly and energy-saving Foamed cement boards are made of cement and fly ash as the main raw materials for production. They will not be burned at high temperatures and will not release toxic chlorine bodies. The support of industrial policy. Long life.
4. Polyurethane composite fireproof insulation board, 1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35-40kg/m3, the thermal conductivity is only 0.018-0.024w/(m.k), which is about half of that of EPS, which is the lowest thermal conductivity of all current insulation materials. Rigid polyurethane is moisture-proof and waterproof. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material, which will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water. Rigid polyurethane is fireproof, flame retardant and high temperature resistant. After adding flame retardant, polyurethane is a kind of flame retardant self-extinguishing material. Its softening point can reach more than 250 degrees Celsius, and it will decompose only at higher temperatures: in addition, polyurethane will burn in its Carbon deposits form on the surface of the foam, and this layer of carbon deposits helps to block the foam below. Can effectively avoid flame extension. Moreover, polyurethane does not produce harmful gases at high temperatures. Good heat insulation function. Due to the excellent heat insulation performance of polyurethane boards, it can reduce the thickness of the building’s outer covering structure under the same heat preservation requirements, thereby increasing the indoor use area. Strong anti-deformation ability, not easy to crack, stable and safe finish. The porosity and structure of polyurethane materials are stable. It is basically a closed-cell structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average service life of rigid polyurethane foam insulation structure can reach more than 30 years under normal use and maintenance conditions. It can be achieved that under normal use conditions during the life of the structure, it will not be damaged under dry, wet or galvanic corrosion, as well as due to external factors such as insect, fungus or algae growth or damage by rodents. Comprehensive cost performance is low. Although the unit price of rigid polyurethane foam is higher than that of other traditional insulation materials, the added cost will be offset by heating and cooling costs.
