一、前言过去船用绝热保温材料,一般采用软木、玻璃纤维,但是从这些材料的保温效果、比重、吸水性、施工条件来看,它们都是不很理想的。六十年代,聚氯乙烯泡沫塑料和聚苯乙烯泡沫塑料,作为船用绝缘材料已被广泛应用。可是这种绝缘材料的施工方法,却以手工为主。即 I. Foreword In the past, marine insulation materials used in marine insulation generally used cork and fiberglass. However, these materials are not ideal for their thermal insulation effect, specific gravity, water absorption and construction conditions. Sixties, polyvinyl chloride foam and polystyrene foam, as marine insulation has been widely used. However, this method of construction of insulating materials, but mainly by hand. which is
