膨胀珍珠岩制品
Expanded perlite products

   本产品是以珍珠岩为主要成分,掺加不同种类粘结剂(水泥、水玻璃、磷酸盐)制成的板、管、壳等制品。它具有容重小、绝热性能好、吸湿能力小、化学性能稳定,并且有很好的抗冻和吸音性能特点,可广泛用于国防工业保湿、隔热和吸音上。
   These products have the shape of board, pipe and shell that are composed of perlite, binders like cement, water glass and phosphate, The main properties are low bulk density, good thermal insulating, hydroscopicity, chemical stability frost resistance and sound absorption. The products are widely used in national defense industries like heat insulating and sound absorpion.
