当前的石棉市场,无论国际、国内,都是“长棉短,短棉长”。长纤维石棉的货很缺,供不应求;短纤维石棉却积压,找不到出路。这是生产石棉和石棉制品的企业普遍头痛的问题。但是,事在人为。成都石棉水泥管厂在四川省建材科研所、省建勘设计院的配合下,利用丰富、廉价的短纤维石棉和500号普通硅酸盐水泥为原料,制成了工作压力为5.4公斤/平方厘米的石棉水泥管。这种石棉水泥管有致密度高、抗渗性强、耐酸碱、抗腐蚀、重量轻、易于加工等优点。目前这种石棉水泥管经过种种实用检验,如在自贡大安盐厂运送卤水,在龙泉驿三家公社喷灌农田,在资阳医院、四川民政局、水辗河住宅楼、省建勘院宿舍、厨房、排污工程等处安装使用,效果都很好。
The current asbestos market, whether international or domestic, is “short cotton and short cotton.” The lack of supply of long-fiber asbestos is in short supply; short-fiber asbestos is backlog and can’t find a way out. This is a common headache for companies producing asbestos and asbestos products. However, things are artificial. Chengdu Asbestos Cement Pipe Factory, with the cooperation of Sichuan Building Material Research Institute and the Provincial Institute of Surveying and Design, uses the rich and inexpensive short fiber asbestos and No. 500 ordinary portland cement as raw materials to create a working pressure of 5.4 kg/sq. Centimeters of asbestos cement pipe. This asbestos cement pipe has the advantages of high density, strong impermeability, acid and alkali resistance, corrosion resistance, light weight, and easy processing. At present, this asbestos-cement pipe undergoes various practical tests, such as the transportation of brine in the Da’an salt factory in Zigong, irrigation of farmland in the three communes in Longquanyi, the Ziyang hospital, the Sichuan Civil Affairs Bureau, the Shuihe River residential building, the construction of the survey hall dormitory, kitchen, and sewage disposal. Projects installed and used, the effect is very good.
