3月25日,地处上海郊县的上海金卫保温材料厂和上海嘉定保温材料厂联合进行并通过了微孔硅酸钙保温产品的技术鉴定。据测试,产品的技术性能为:容重200kg/m~3,抗折强度0.4兆帕以上,导热系数(常温下)0.048kcal/m.h·℃以下,线收缩率(650℃条件下)2.0%以下。经试点应用,该材料使用中其表面温度、热损失明显降低,使用效果优于珍珠岩,岩棉硅酸铝复合制品等其它品种。同期,全国建筑工程材料情报信息网硅酸
On March 25, Shanghai Jinwei Thermal Insulation Material Factory, located in the suburbs of Shanghai, and Shanghai Jiading Insulation Material Factory jointly conducted and passed the technical appraisal of microporous calcium silicate insulation products. According to tests, the technical performance of the product is: bulk density 200kg/m~3, flexural strength 0.4 MPa or more, thermal conductivity (under normal temperature) 0.048kcal/mh·°C or less, linear shrinkage (under 650°C conditions) 2.0% or less . After the trial application, the surface temperature and heat loss of the material are significantly reduced during use, and the use effect is better than that of perlite, rock wool aluminum silicate composite products and other varieties. During the same period, the national construction materials information and information network silicic acid
