Production and processing of flue plate double long card

Double Lung brand new fire temperature and fire is the use of flue lightweight, high strength, high fire-resistant inorganic composite sheet performance, glass magnesium board has good fire performance, is non-combustible sheet, the flame continued to burn time is zero, 800 ℃ does not burn, 1200 ℃ no flame, reaching the highest level of fire safety class A1 non-combustible, and high-quality production keel partition system, the thermal conductivity of 0.216w / cm? k, than the sand-lime brick diced 1.1w / cm? k more insulation, fire endurance more than three hours, a fire burning process can absorb a lot of heat, delay ambient temperature. Using the product produced composite cement chimney flue compared with the original, in the fire, bending, vertical bearing capacity, impact resistance, fire resistance of other aspects, has incomparable superiority. Flue board Features: 1, high fire resistance, flue plate not only flame-retardant, non-flammable, the use of flue plate flue fire resistance made even reach 90-120 minutes, while cement flue can reach Class B fire protection requirements . 2, low cost, cement flue is using molds and intraocular most humble of manufacturing process, low productivity, high labor costs. The new stack is based on the design drawings, the flue plate was cut indicators requires the installation site from a combination of direct, production speed, thus production costs are relatively low. 3, lightweight, high strength, flue plate using inorganic composite materials and composite made of lightweight aggregate; cement flue is made of cement, sand, and therefore, the use and production of new flue plate flue, light weight, and high strength, more suitable for modern high-rise residential fire, smoke design requirements. 4, the design and manufacture of flexible flue plate flue specifications can produce a variety of flue sheet, then cut, the combination can be based on the specifications of the flue, and cement chimney flue according to design, first First manufacture of molds, and kind of the die can only produce a flue. 5, the construction is simple, the new flue flue plate combination with lightweight, high strength, easy handling. Flue technical requirements of the specifications: according to the national standard flue flue plate size is generally: 1220 * 3000 * 15-18mm, built-in glass fiber cloth layer 4 -6 layer density of about 1.1, namely: every cubic m flue sheet quality 1.1 t
