Gypsum plaster block is the main raw material, or adding a variety of added material, additives, lightweight aggregate, add water, stirring, pouring forming, made of natural or artificial drying. With light weight, neat appearance, smooth, precise size, volume stability, fire protection, thermal insulation, sound insulation and good durability, can regulate indoor humidity capabilities and other features. Quality of their products comply with current building materials JC / T698-2010 "gypsum block", GB-6566-2001 "building materials radionuclide limited" industry standards, installation execution Atlas for 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 (waterproof masonry) 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 of the apparent density of hollow block should ≤700kg / m3, a single piece of quality should ≤28kg. Masonry surfaces should be smooth flatness flatness should ≤1.0mm. Fracture load block should have sufficient mechanical strength, fracture load values ??should ≤1.5kN. Softening coefficient softening coefficient blocks should ≥0.6, which applies only to soften targets gypsum block moisture. Fire Performance 100mm and 120mm gypsum block Gypsum block the fire resistance was more than four hours. Soundproof single block wall soundproofing amount 45-50dB, composite wall can reach 50dB above the amount of noise. High strength and flexural strength of 5000N block over, after notching flexural strength of 3000N piping above, a single point hanging force 800-1000N. Masonry construction convenient aspect tongue and groove edges, respectively, to facilitate the construction of key joints; blocks can be sawed, planed, nailed, easy masonry walls can easily be slotted cloth line, hanging a variety of objects, fast, workability Okay. Easy to crack shrinkage value is low, easy to produce cracks, no deformation. Cost-effective block size precision, surface roughness, surface no longer plastering process, that shorten the construction period, greatly reducing the cost of refined decoration; increased use of space, 100 square meters of room to increase the use of more than 120 blocks 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.
