Wholesale supply insulation rock wool board hard rock wool board

Rock wool is a selection of basalt as main raw material, made by high melting of artificial inorganic fibers. Has the characteristics of light weight, small coefficient of thermal conductivity, sound-absorbing performance is good, not burning, the chemical stability is good wait for. It is a new type of insulation, heat insulation, sound-absorbing material. Rock wool products has the general characteristics of the rock, also has the waterproof, thermal insulation, insulation insulation performance, have certain chemical stability, long-term use will not deliquescence even in humid conditions. According to the method of JISA95-1979 experiment, the hydrophobic rate in 98% above. Because of its products not containing fluorine (F-), chlorine (Cl), so it has no corrosion to equipment. The Tianjin Fire Research Institute of the Ministry of public security inspection identified as incombustible material, buildings, pipelines, storage tanks, distillation tower, boiler, flue, heat exchanger, heat insulation, excellent fan and travel and other industrial equipment, insulation, cold insulation, sound-absorbing material.The resin cotton is a selection of diabase and basalt slag as the main raw material, after the high temperature melting in the process of centrifugal spray into the special adhesive and waterproof agent and made of resin and waterproof rockwool rockwool.The factory in the absorption of the basis of domestic and foreign advanced technology and equipment, according to China's national conditions and the features of raw materials, together with the domestic rock wool industry experts developed cotton production line and the large resin plate, pipe production line has reached the clever combination makes it more perfect. Fill the improvement of other production line can not be blank, make large tube and shell and tube shell and different rock wool board product quality and specifications species diversity more users.Scope of application:Rock wool products wide range of uses, applicable to the construction, petroleum, electric power, metallurgy, textile, defense, transportation and other industries, is the ideal material for tank, boiler, flue, heat exchanger, fan, and other industry equipment heat insulation, sound insulation.The main technical indicators:Technical performance specifications noteThermal conductivity of W/ (m.k) 0.030-0.044 at room temperatureSlag ball content (diameter >0.25mm) below 12 with GB11835-89Non-inflammable A with GB5464The fiber diameter (4-7 μWorking temperature (-268-700 ℃)Acidity coefficient > 1.5 SiO2+AlO2ReachCaO+MgOThe moisture absorption rate (%) > 5Density tolerance (%) + 10 with GB11835-98Resin content of rock wool board with GB11835-98 ≥ 3Rock wool felt ≥ 1Rock wool pipe ≥ 3.5Hate water rate (%) of >98 with GB5480 http://shop1349801846586.cn.alibaba.com/
