近来,海外研制成功一种高强度无石棉绝热材料。该绝热材料不仅强度高、韧性好,而且耐热,极易于切割加工,由于不含石棉,也属于一种环保型材料。过去,绝热材料多数是掺石棉纤维或纸浆纤维制成。但它们具有以下缺点:掺石棉纤维,制品切割时产生大量石棉粉尘,危害健康;掺纸浆纤维,其 Recently, a high-strength non-asbestos insulation material was successfully developed overseas. The insulation material is not only high strength, good toughness, but also heat-resistant, very easy to cut and process, because it does not contain asbestos, also belong to an environmentally friendly materials. In the past, adiabatic materials were mostly made of asbestos fibers or pulp fibers. However, they have the following disadvantages: asbestos fibers, which produce a large amount of asbestos dust when cut, are harmful to health; mixed with pulp fibers,
