水玻璃具有不同化学成分、比重、模数,要得到一个质量较好的型壳,则必须对水玻璃加以处理。一般对水玻璃的处理,采用彼尔欣方法,但这种方法处理的水玻璃常使型壳强度偏低。为提高型壳质量,我们经生产实践摸索一套处理水玻璃的方法——计表法。它具有如下特点: 1.按表查出加入氯化铵量,简单,不用计算,适应生产。 2.稳定生产,克服彼尔欣方法型壳偏低和一般计算法水量少、壳裂等 Water glass with different chemical composition, specific gravity, modulus, to get a good quality shell, you must be treated with water glass. The general treatment of water glass, using Phelink method, but this method of processing water glass shell often low strength. In order to improve the quality of the shell, we explore a set of methods to deal with water glass through production practice - meter method. It has the following characteristics: 1. According to the table found to join the amount of ammonium chloride, simple, without calculation, to adapt to production. 2. Stable production, to overcome the low Pyhel method shell and the general calculation of water less, such as shell cracking
