Manufacturer price Fiber cement board expanded vermiculite
Product functions and features
Vermiculite has many excellent performances such as insulation, cold resistance, antibacterial, fire prevention, water absorption, sound absorption ans so on. Under the 800 ~ 1000 ℃ calcination 0.5 ~ 1.0 minutes, it can rapidly increase volume 8 ~ 15 times, Max. up to 30 times. After the expansion, the proportion is 50-200 kg/m3, Color turns into golden or silver, then generate a texture osteoporosis expanded vermiculite,but no acid, its dielectric properties are poor.
After high temperature roasting the raw vermiculite, the volume can quickly expand several times to dozens times, after the expansion of vermiculite average unit weight is 100 ~ 130 kg/m 3, with small air interval layer, so it is a good heat preservation, heat insulation, sound-absorbing, frozen erosion resistant building materials, fillers, coating, and refractory industry. Expanded vermiculite are widely used in construction, metallurgy, chemical industry, light industry, machinery, electric power, petroleum, environmental protection and transportation department, foreign mainly used in construction, insulation, packing and agriculture, horticulture, etc.
