Vermiculite insulation, cold-resistant, anti-bacterial, fire, water, sound absorption, excellent performance, after high temperature baking raw vermiculite, expanded its volume can quickly several times to several times, average bulk density of the expanded vermiculite 100 ~ 130kg / m 3, with a small air gap layer, so it is a good thermal insulation, sound absorption, resistance to cold corrosion materials, industrial fillers, paints and refractories. Vermiculite is used vermiculite insulation layer has a porous, lightweight, high melting point characteristics, most suitable for high-temperature insulation materials (1000 ℃ or less) and fire-proofing insulation. By cement vermiculite experiment fifteen centimeters thick high temperature combustion at 1000 ℃ for 4-5 hours, around the back of the temperature is only 40 ℃. Seven centimeters thick vermiculite fire welding flame burning through the network under 3000 ℃ high temperature for five minutes, the front melting, holding the back of his hand still feel hot. So it is more than all the insulation material. Such as asbestos, diatomaceous earth products. Vermiculite insulation materials for high temperature facilities, such as smelting industry, insulation bricks, insulation board, insulation caps. Those who need thermal insulation of equipment, can use vermiculite, cement and vermiculite products (vermiculite brick, vermiculite, vermiculite tubes, etc.) or asphalt vermiculite insulation products. Such as walls, roof, cold storage, boilers, steam pipes, liquid pipes, water towers, transform furnace, heat exchangers, vault and other dangerous goods. Common models are: 20-40 mesh, 40-60 mesh, 80-100 mesh, 200 mesh, 1-3MM, 2-4MM, 3-6MM, etc.
