有人把“节能”称之为第五能源。一些工业发达国家为了保护能源和寻求新能源,作了大量的努力,方针是研究有效地利用能源,从节约能源中找能源。于是在建筑上,在工业上使用保温材料被看作是节能之本。人类从使用保温材料至今已有1000多年的历史。在早期是使用较低级的材料(如粘土掺纤维——植物纤维等)。19世纪末,硅藻土、矿物纤维、石棉和玻璃棉等新材料得到了实际应用。本世纪30年代以后,随着造船、钢铁、石油和海洋等工业的迅速发展,保温材料与日俱 Some people call “energy saving” the fifth energy source. Some industrialized countries have made great efforts to protect energy and seek new energy. The principle is to study the effective use of energy and find energy from energy conservation. Therefore, in construction, the use of insulation materials in industry is seen as the basis for energy conservation. Humans have been using insulation for more than 1,000 years. In the early stages, lower grade materials (such as clay-doped fibers - plant fibers, etc.) were used. At the end of the 19th century, new materials such as diatomaceous earth, mineral fibers, asbestos, and glass wool were put to practical use. After the 30s of this century, with the rapid development of shipbuilding, steel, petroleum, and marine industries, insulation materials have become
