石棉水泥制品用挤压法生产有许多优点:可连续生产,成型设备效率高,可全部实现机械化和自动化。制品尺寸精确,不需要其他机械再加工,制品长度仅受设备构造的限制,水泥和石棉不浪费。苏联一家试验性生产企业,用挤压法生产石棉水泥挤压空心板、槽型板和窗台板。该企业的石棉水泥板车间的围护结构是用这种挤压板建成的。许多工业、民用和农业建筑也使用这种板材。石棉水泥挤压空心板适合作墙体围护结构、隔墙板、屋面板和隔音天花板。在空心内填充掺人造
The production of asbestos cement products by extrusion has many advantages: it can be produced continuously, the efficiency of molding equipment is high, and it can be fully mechanized and automated. The product is precise in size and does not require any further mechanical reworking. The length of the product is only limited by the construction of the equipment. Cement and asbestos are not wasted. A pilot production company in the Soviet Union used extrusion to produce asbestos-cement extruded hollow slabs, trough boards and sill boards. The company’s asbestos-cement-cement workshop enclosure structure was built using this extruded board. Many industrial, civil, and agricultural buildings also use this type of sheet. Asbestos-cement extruded hollow panels are suitable for wall enclosures, partition panels, roof panels and acoustical ceilings. Filling man-made in the hollow
