Introduction hydrophobic perlite is a new insulation material, its low thermal conductivity, common around 0.045W/mk, the lowest in 0.041W/mk. Its exterior has a layer blocking glass, so that in itself has a high compressive strength, not easy to damage, which can greatly reduce breakage during use, so that the effective maintenance practices insulation effect. While reducing the absorbent material, reducing the proportion with the amount of water, and the material was significantly shorter overall drying time, help to improve construction efficiency. Characteristics of a hydrophobic perlite non-toxic, odorless, environmentally friendly;. Hydrophobic perlite lightweight, fire, moisture, corrosion-resistant; easy hydrophobic perlite construction, lightweight, high strength, thermal insulation; hydrophobic perlite insulation board ( FSG) in line with the national standard GB8624-2006A1-level non-combustible standards. 2. Pulp hard, fine pulp surface, high bond strength, crack resistance, no cracking, can not afford to incite. 3 products easy construction, simple operation, easy to use, the right to use all kinds of different construction levels of personnel, can be applied, the system blocks spray or paste. 4 for a variety of wall, roof, roof, metal construction, thermal insulation and fire wood frame house. 5 more suitable type applied in water conservancy, hydropower construction, water treatment or water retaining dam project due by the water layer and non-cracking problem by the temperature difference between the water layer is formed. Life durable, reliable performance. Applications 1. Hydrophobic expanded perlite porous particle diameter 0.15 ~ 1.5mm air particles, and is the preferred filler material. 2 has a low bulk density between 0.06-0.20g/cm3. As the polymer filler, other than the mineral filler product is much less, by weight of the small load, saving an amount of polymer, thus reducing product costs. 3 low price, hydrophobic expanded perlite based on a small bulk density, compared with the same weight of other filler material installed in the CD in the polymer production cost. 4 electrically insulating, water-repellent glass good electrical insulation, as a filler material for a variety of electrical switching apparatus and insulating material. 5 soundproofing, hydrophobic expanded perlite can block and absorb sound, can be used for insulation materials. 6 acid, the main component of the hydrophobic expanded perlite SiO2 and Al2O3, close to neutral, in a variety of solvents, acids, alkali, salt is stable. 7 low thermal conductivity, thermal coefficient (0.036-0.054w/mk), glass beads can be used for the hydrophobic material and a heat insulating material. 8 good thermal stability. Thermal stability over 1,000 ° C, especially for fire-resistant, fire retardant material. 9 retardant. Hydrophobic expanded perlite inorganic metal oxides, less than 1000 degrees Celsius, does not decompose at high temperatures, easily deformed, as a polymer filler material can improve the flame retardant properties of the polymer used for building materials and paint industries. 10 Low water absorption: the absorption of hydrophobic expanded perlite is less than 10%. Our purpose is to provide a variety of horticultural perlite, perlite air separation device, do washing powder with pearlescent sand, perlite filter aid, perlite insulation board, construction glass beads, perlite and other products, according to customer request processing production of various indicators of perlite products.
