正辛醇改善浆料涂挂性的试验研究

Experimental Investigation of Improving the Coating Property for Octanol

在水玻璃粘结剂配制的浆料中,加入正辛醇可以改善涂挂性,从源头上遏制或者减少气泡的生成.正辛醇的加入量是水玻璃质量的0.30%.把表面活性剂JFC加入到氯化铵、结晶氯化铝硬化液中,JFC加入量为氯化铵、氯化铝溶液质量的0.05%～0.10%,型壳的表面涂层和铸件质量得到满意的效果.

In slurry made up with sodium silicate binder put into octanol, which can improve the coating property, then gas cavity is repressed or decreased. The quantity addition of octanol is 0.30% quantity of water-glass. JFC is put into ammonium chloride and crystal aluminum chloride hardening liquid, the quantity addition of octanol ranges from 0.05% to 0.10% quantity of ammonium chloride and aluminum chloride, Surface coating and cast quality of shell have a famous effect.
