Gypsum block is cast as the main raw material, or All feeds, additives, lightweight aggregate, add water and stir, pouring forming, made of natural or artificial drying. With light weight, neat appearance, smooth surface, precise size, volume stability, fire protection, thermal insulation, sound insulation and good durability, it can regulate indoor humidity function and other features. Quality of their products in line with current building materials JC / T698-2010 "Gypsum", GB-6566-2001 "construction materials radionuclide limited" industry standards, installation of Atlas implementation of 04J114-2 "gypsum block inner compartment wall. " Product Specifications Product Name: 90mm gypsum block Specifications: JN-GB1001-660 × 500 × 90mm (hollow) Specifications: JN-GB1002-660 × 500 × 90mm (moisture block) Specifications: JN-GB1003-660 × 500 × 90mm (waterproof masonry) Product name: 120mm gypsum block Specifications: JN-GB1201-660 × 500 × 120mm (hollow) Specifications: JN-GB1202-660 × 500 × 120mm (moisture block) Products Specifications: JN-GB1203-660 × 500 × 120mm (water block) Product name: 200mm gypsum block Specifications: JN-GB2001-660 × 300 × 200mm (hollow) Specifications: JN-GB2002-660 × 300 × 200mm (moisture block) Specifications: JN-GB2003-660 × 300 × 200mm (water block) physical performance requirements Apparent density hollow block should ≤700kg / m3, monolithic quality should ≤28kg. Flatness block surface should be smooth, flatness should ≤1.0mm. Fracture load block should have sufficient mechanical strength, fracture load value should ≤1.5kN. Softening coefficient softening coefficient block should ≥0.6, the softening index applies only proof gypsum block. Product performance fire 100mm and 120mm gypsum block Gypsum fire resistance of greater than 4 hours. Soundproof single block walls amount of noise 45-50dB, composite wall insulation can reached more than 50dB. High strength and flexural strength of 5000N or more blocks, after notching piping bending strength of 3000N or more, a single point hanging force 800-1000N. Construction of vertical and horizontal edges of the block, respectively convenient tongue and groove, mortise key ease of construction; blocks can be sawed, planed, nailed, easy to masonry walls can easily be slotted cloth line, hanging various objects, fast, workability Okay. Easy to crack shrinkage value is low, easy to crack, not deformed. Cost-effective block size precision, surface roughness, surface no longer plastering process, that shorten the construction period, greatly reducing fine decoration costs; increased use of space, 100 square meters of room to increase the use of 120 blocks than using 240mm solid clay indoor area 5 m. Green, environmentally friendly industrial waste gypsum as raw material in the production process does not produce waste, no pollution, no poisonous and radioactive substances; the role of sterilization sterilization, can effectively inhibit bacterial survival and spread.
