fiber ceiling board

fiber ceiling boardis made of high-density Alpha gypsum powder,enhanced glass fiber and environment friendly microelement. Main material introduction Alpha gypsum powder is picked and high-purity gypsum powder as the base material which is produced with the most advanced production ,supplemented by a variety of environment-friendly additive. Glass fiber is a kind of non-metallic inorganic material with good performance. The thickness is uniform,resin is easy penetration to fit with the mould well,Laminate is with good light transmission, etc. Glass fiber is often used as reinforced material in various fields.The unique alkali-free glass fiber felt used by our company is made of fiberglass protofilament or the roving with cutting into 50mm long through special chemical adhesibes and mechanical role.II GRG product feature High strength,impact resistance Expetimental results show that the maximum breaking for GRG product can load up to 1200N(thickness in 2cm),exceeding the national standard JC/ T799-1988(1996)decorative gypsum board 10 times on the fracture load 118N.GRG Product can be uniform and stable to withstand compression,shock,and barcol hardness and the similar strength test with no deformation,no subsidence,no bending and no thermal expansion. GRG product not only possess high hardness,but also high flexibility,which can be made into a variety of sizes,shapes and design moldings.As it is easy to use,it has been used in a complex ceiling and decoration.High Density and Light Density of GRG products can reach 1880kg/m3 with 3.2MM to 8.8MM thickness ( also special requirement can be made), the weight per square can reach 4.9kg to 9.8kg, which will reduce the weight of the main building and components . Fire Performance GRG materials belong to A-grade fireproofing material,when the fire broke out,it can release the equivalent of its own weight of 10-15% of the water,in addition to fire retardance,which can greatly reduce the surface temperature, at last reducing fire damage. Moisture resistance GRG product is within 10% on water absobing capacity,which can be used to the places full of damp moisture. Environmental protection GRG materials with no odor is a green one,which of radionuclide limits applying to GB6566-2001 specified in Class A decorative material,also being recycled. Good Acoustic Effect Inspection results show that GRG materials in 4MM thickness handle professional requirements on acoustic reflex, through the loss of 500Hz23db,100Hz27db and the weight with air-dry.After a good design ,it may constitute a good sound-absorbing structure,to achieve sound insulation and sound-absorbing role. Convenient Construction GRG can be made any shape ,be large production and be partitioning according to the design.on-site processing performance is good,quick to install and flexible, being formed a complete shape,especially for the holes,arcs,angles and other nuances in order to ensure no errors. Short production cycle The demoulding time of GRG product requires only about 30minutes,72 hours for drying in the air. Easy construction GRG product can be any shape and large to production and partition according to the designer. As on-site processing performance is good,quick to install and flexible, it is easy to joint closely for the whole shape,especially for the holes,arc,angle and other part in order to ensure there are no errors.
