1.The wax molds are dipped into waterglass solution, with surface coated by the solution.
将蜡件组浸入含有璃等涂料缸中,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.
璃砂强度越高,其溃散性通越差。
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,所研究棕刚玉涂料是一种质中性抗粘砂涂料,适用于粘土砂、璃砂及树脂自硬砂铸型和型.
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.
