膨胀珍珠岩及其制品,在我国是六十年代发展起来的一种新型保温材料。近些年来,由于国家重视了节能工作,所以需求量越来越大。目前,膨胀珍珠岩制品的粘结材料,主要采用石油沥青、水泥、水玻璃及乳化石油沥青等短线产品,所以供应得不到保障,而且价格昂贵,影响和限制了生产的发展。为解决这个问题,我们进行了用白城的白粘土做粘结材料生产白粘土膨胀珍珠岩制品的试验研究工作,取得了较顺利的进展。并已于1984年4月通过了鉴定。
Expanded perlite and its products are a new type of insulation material developed in China in the 1960s. In recent years, due to the country’s emphasis on energy conservation, the demand is increasing. At present, the bonded materials of expanded perlite products mainly use short-term products such as petroleum asphalt, cement, water glass, and emulsified petroleum asphalt, so the supply is not guaranteed, and the price is high, affecting and limiting the development of production. In order to solve this problem, we have conducted experimental research on the production of white clay expanded perlite products from Baicheng’s white clay as a bonding material, and achieved relatively smooth progress. And in April 1984 passed the appraisal.
