北京加气混凝土厂研制成功一种新型的硅酸钙防火保温建筑材料。这种材料在性能上具有普通硅钙制品的特点,在生产工艺上却不同于一般硅钙制品的生产方式,而是具有加气混凝土的工艺特点,可以制作成各种规格形状的平板,各种口径的高温保温管。这种硅酸钙制 Beijing Aerated Concrete Plant has successfully developed a new type of calcium silicate fireproof and heat-insulating building material. This material has the characteristics of ordinary silicon-calcium products in terms of performance, but it is different from the production method of general silicon-calcium products in the production process, but it has the process characteristics of aerated concrete and can be made into flat plates of various specifications and shapes. A variety of high-temperature insulation tubes. This kind of calcium silicate
