憎水水玻璃珍珠岩制品是在原水玻璃珍珠岩制品的基础上,添加一定量的憎水材料,从而改善了原制品吸湿、吸水的缺点。该制品容重小于2000N/m~3,抗折强度大于0.2MPa,憎水率大于98％,是潮湿环境下,较理想的保温材料之一。水玻璃珍珠岩制品是珍珠岩制品中性能比较好的保温材料。该制品具有容重小,强度高、耐温性好等优点,在电力、化工、特别是城市供热系统得到较为广泛的应用。但是,该制品和大多数无机保温材料一样,防潮、防湿性能差,吸水率大。吸水率大不仅影响材料的强度,更重要的是将大大降低材料的保温、隔热效果。由于目前聚氨酯泡沫材料紧张,价格昂贵,石油保温工程面临选择廉价保温材料的问题,憎水水玻璃珍珠岩制品定将以廉价的优势得到广泛的应用。
Yushui water glass pearlite products are based on the original water glass perlite products, adding a certain amount of hydrophobic materials, thereby improving the original product moisture absorption, absorbent defects. The bulk density of the product is less than 2000N/m~3, the flexural strength is more than 0.2MPa, and the water repellency rate is more than 98%. It is one of the most ideal thermal insulation materials in the wet environment. Water glass perlite products are better insulation materials in perlite products. The product has the advantages of small bulk density, high strength and good temperature resistance, and is widely applied in electric power, chemical industry, and especially urban heating system. However, this product, like most inorganic heat-insulating materials, is poor in moisture resistance and moisture resistance, and has a large water absorption rate. The high water absorption not only affects the strength of the material, but more importantly, it will greatly reduce the insulation and heat insulation of the material. Due to the current tense and expensive polyurethane foam materials, the petroleum insulation project is faced with the problem of choosing low-cost insulation materials. Surabaya Water Glass Perlite products will be widely applied with low prices.
