化学建材以它耐腐蚀,强度高、质量轻、寿命长,安装运输方便,阻燃、隔音、隔热,成本低等优点列为国家建设部“九五”期间重点推广应用的十项新技术之一。现已由 PVC 硬管,发展到第二代产品双层波汶管和第三代新产品,芯层发泡管。广泛应用于建筑业给、排水管,门窗,室内装饰板材,农业排管,市政地下管道,邮电通讯,电线电缆导管,经过改进配比配方后可用于暖气管道,石油管道,化工管路等方面。发展 PVC新化学建材,以塑代钢代铝是缓解国内钢材供需矛盾的一项重大技术政策,以化学建材相应的独特性而成为继钢材,木材、水泥后的第四大建材,以节约生产能耗及使用能耗已 The chemical building materials are listed as the ten items of key promotion and application during the Ninth Five-Year Plan period of the National Ministry of Construction for its advantages of corrosion resistance, high strength, light weight, long service life, convenient installation and transportation, flame retardant, sound insulation, heat insulation, and low cost. One of the new technologies. It has been developed from PVC hard pipe to the second-generation double-layer Bovin tube and the third generation of new products, core foam tubes. Widely used in construction industry, drains, doors and windows, interior decorative plates, agricultural drainage pipes, municipal underground pipes, post and telecommunications, wire and cable ducts, after improved formulation can be used for heating pipes, oil pipelines, chemical pipelines, etc. . The development of PVC new chemical building materials, plastic generation of steel aluminum is a major technical policy to ease the contradiction between domestic steel supply and demand. With the corresponding uniqueness of chemical building materials, it becomes the fourth largest building material after steel, wood and cement to save production. Energy consumption and use energy consumption
