干态膨胀珍珠岩是一种超轻级人造填料,孔隙密集,保温性能好。但是,由于其吸水量大,因而延长了制品的热养护时间,相应地增加了养护所需的热能消耗,而且还会降低制品均热物理性能。因此,在生产保温材料和保温构件时,如果采用膨胀珍珠岩做填料,只有降低膨胀珍珠岩的吸水性,才能提高其使用效益。 Dry-state expanded perlite is an ultra-light artificial filler with dense pores and good thermal insulation properties. However, because of its large amount of water absorption, the heat-curing time of the product is prolonged, accordingly the thermal energy consumption required for curing is increased, and the physical properties of the product are also reduced. Therefore, in the production of insulation materials and thermal insulation components, if the use of expanded perlite as filler, only to reduce the water absorption of expanded perlite can improve its use efficiency.
