Glass magnesium fire board is also called glass magnesium board, magnesium oxide board, magnesite board magnesia board. The material components for producing glass magnesium fire board are active high-purity magnesium oxide (MgO), high-quality magnesium chloride (MgCl2), alkali-resistant glass fiber cloth, plant fiber, non-combustible light perlite, chemically stable Lide powder, polymer, High-performance modifier.
Glass magnesium fire board has high temperature resistance, flame retardant, sound absorption and shock resistance, waterproof and moisture resistance, insect resistance, lightweight anticorrosion, non-toxic, tasteless and pollution-free, can be directly painted, directly veneered, can be air nails, directly on tiles, the surface is relatively Good colorability. High strength, flexible bending, extremely convenient decoration, can be sawed, nailed, and sticky.
The glass magnesium fire board has good fire performance, is a non-combustible board, the flame has a continuous burning time of zero, 800 ℃ does not burn, 1200 ℃ has no flame, reaches the highest fire and non-combustible level A1, and the partition system made with high-quality keel, fire resistance limit reaches 3 For more than hours, it can absorb a large amount of thermal energy during the fire and burn, delaying the increase of ambient temperature.
Concrete aggregates; lightweight, thermal insulation, sound-absorbing panels; fire-resistant roofing and lightweight anti-freeze, earthquake, fire, radiation protection and other high-rise building engineering wall fillers, mortars and other building materials; various industrial equipment, pipeline insulation layers; The inner walls of various cryogenic and cold storage projects; the inner walls of low-boiling liquid and gas storage and the inner walls of transportation vehicles.
The glass magnesium fire board does not contain asbestos, formaldehyde, benzene and harmful radioactive elements, and it is smokeless, non-toxic and odorless in case of fire. The produced materials are natural mineral powder and plant fiber. The production process is naturally conserved, with low energy consumption, no pollutants, energy saving and environmental protection. The surface of the board does not contain powder, and its unique natural pore structure can adjust indoor temperature. Make the living room and office more comfortable.
There are three types of perlite geological divisions of the industrial type of the deposit.
These three divisions are similar to each other, or complement each other, except that the restrictions on the chemical composition are slightly different.
(1) The first classification: k0 refers to the expansion factor of the ore obtained by the factory roaster test, which is usually about 2 times the k of the laboratory roasting test, as shown in Table I.
The three classifications of ore grades are mainly based on the swellability of the ore. Which grade is actually used should be decided specifically according to needs.
All three divisions associate the chemical composition of a rock with its expansion factor. Because the expansion factor for perlite does not necessarily depend entirely on its chemical composition. 彩板防火门和普通防火门区别 Previous: The difference between color plate fire door and ordinary fire door 需要设置避难间的场所_避难间设置范围 Next: The place where the refuge room needs to be set up_the scope of the refuge room setting
