上海各建筑工程公司,去年下半年采用菱苦土木屑代替石棉水泥制作水落、水管和水斗,已经获得成功。现将这三种制品的制作经验作一介绍:一、配合比例:菱苦土木屑胶泥的配合比(以体积计)为:菱苦土1木屑1.5—1.75滑石粉0.1—0.3氯化镁溶液浓度22—24°B1′(比重1.18—1.20)(氯化镁的质量应该采用较好的,其中MgCl_2·6H_2O的含量应在96%以上,否则将影响制品的质量。)
Shanghai construction and construction companies have succeeded in adopting hard-boiled earth and wood chips instead of asbestos cement to make water fall, water pipes and water buckets in the second half of last year. The production experience of these three kinds of products is now described as follows: 1. Mixing ratio: The ratio (by volume) of the bitter-soil-wood-sawdust clay is: magnesite-bitter earth 1 wood chips 1.5—1.75 talcum powder 0.1—0.3 magnesium chloride solution concentration 22 -24°B1’ (specific gravity 1.18-1.20) (The mass of magnesium chloride should be better, and the content of MgCl_2·6H_2O should be above 96%, otherwise it will affect the quality of the product.)
