煤、电、石油和天然气,被称之为四大常规能源.自1973年爆发全球性能源危机以来,节能便成为举世瞩目的重大问题,于是便把节能称作“第五常规能源”.当前,我国能源十分紧张,有20～30%的生产力,因缺乏能源而不能发挥作用.所以抓节能是当务之急,而节能工作中,最现实、最有效的措施便是大力发展、积极推广、应用保温材料,这是世界各国普遍采取的措施.过去,由于我国建筑物不强调保温,工业保温也缺乏严格的规定和要求,保温材料生产量小,应用面窄,又加上地区性的不平衡,
Coal, electricity, oil and natural gas are called the four major conventional energy sources. Since the outbreak of the global energy crisis in 1973, energy conservation has become a major issue that attracts worldwide attention. Therefore, energy conservation has been called the “fifth conventional energy source.” China’s energy is very tight, with 20 to 30% of its productivity, and it is unable to function due to lack of energy. Therefore, it is imperative to focus on energy conservation, and the most realistic and effective measures in energy conservation are vigorous development, active promotion, and application of thermal insulation. Materials, which are commonly adopted by countries in the world. In the past, due to the lack of insulation in buildings in China, industrial insulation also lacks strict regulations and requirements, the production of insulation materials is small, the application is narrow, and regional imbalances are added.
