矿棉、玻璃棉是一种轻质、高效、耐久、经济的保温、吸声材料,具有导热系数低、容量小、不燃、耐腐蚀、防虫、防霉等优异性能,能广泛应用于国民经济各个部门,在节约能源、降低噪声、保护环境方面发挥着重要作用。我国从50年代后期开始生产,到目前已拥有70多个工厂(或车间),生产能力已达十几万吨。矿棉、玻璃棉的应用面越来越广。在建筑和工业保温设备上的应用,取得了良好的效果。据哈尔滨市测定每户20米~2的住宅采用3/4砖墙夹玻璃棉保温的住宅,比传统的两砖墙住宅,冬季每昼夜可省煤15—25％,一个采暖期可省煤半吨多,如能在20多万米~2住宅中推广使用玻璃棉保温,一冬就可节煤5,000吨。用于工业绝热保温效果更为明显。假如我国18万台锅炉及其输热系统上都利用,达到保温完好状态,一年就可节煤上
Mineral wool and glass wool are lightweight, efficient, durable, and economical materials for heat preservation and sound absorption. They have excellent properties such as low thermal conductivity, small capacity, non-flammability, corrosion resistance, pest control, and mildew resistance, and can be widely used in the national economy. Various departments play an important role in saving energy, reducing noise, and protecting the environment. China began production in the late 1950s and has more than 70 factories (or workshops). The production capacity has reached more than 100,000 tons. The application of mineral wool and glass wool is getting wider and wider. The application in building and industrial insulation equipment has achieved good results. According to Harbin’s determination of residential houses of 20m~2 per household, 3/4 brick-clad glass-cotton-insulated residential buildings can save coal by 15-25% per day and night than traditional two-brick residential buildings. One heating period can save coal. More than half a ton, if you can promote the use of glass wool insulation in more than 20 million meters ~ 2 residential, one winter can save 5,000 tons of coal. For industrial insulation insulation effect is more obvious. If China’s 180,000 boilers and their heat input systems are used to achieve a state of intact insulation, coal can be saved in one year.
