1983年,国家经委、计委组织专家重点调查了98个具有代表性的企业,发现供热系统的热损失在50%以上。热损失大的原因是多方面的。主要原因之一,是普遍不重视保温。所以,发展新型保温材料及其制品的生产,在设计、施工、生产中重视保温技术,宣传并严格执行绝热工程的各种法规,是节能工作的重要环节。一、保温材料要考虑的主要性能(一) 使用温度是指保温材料及其制品所能承受的被保温物体的界面温度。这个温度范围当然越大越好,在符合使用温度的情况下,保温材料及其制品的性能不应有变化,使用寿命不应缩短。
In 1983, the State Economic Commission and the Planning Commission organized experts to survey 98 representative enterprises and found that the heat loss of the heating system was over 50%. There are many reasons for the large heat loss. One of the main reasons is that insulation is generally not valued. Therefore, the development of new types of insulation materials and their production, in the design, construction, production, attention to insulation technology, and promote the strict implementation of various laws and regulations of thermal insulation projects, is an important part of energy conservation. First, the main properties of insulation materials to be considered (A) The use of temperature refers to the insulation material and its products can withstand the interface temperature of the object being insulated. Of course, the larger the temperature range, the better. In the case of using the temperature, the performance of the insulation material and its products should not change, and the service life should not be shortened.
