水玻璃

1.The wax molds are dipped into waterglass solution, with surface coated by the solution.

将蜡件组浸有水玻璃等涂料的缸中，涂上涂料。

2.In general, the higher the atmospheric temperature strength of the sodium silicate sand is, the more deteriorative its collapsibility becomes.

水玻璃砂的常温强度越高,其溃散性通常越差。

3.The results have shown that the brown alundum coatings are high-class neutral refractory coatings and are used with success in iron and steel cast-ings.

试验结果表明,所研究的棕刚玉涂料是一种质的中性抗粘砂涂料,适用于粘土砂、水玻璃砂及树脂自硬砂的铸型和型芯.

4.Abstract: When water glass seriflux as chemistry injection material, its kinetic viscosity is varying with time, so the process of seriflux permeating in the sand is complicated.

水玻璃类浆液作为化学灌浆材料，其粘度在随化，因此浆液在砂土中的渗流过程较复杂。
