在我厂铸工车间生产中,经常有一些需试水压的铸件,特别是一些有色合金铸件,如铝合金件及铜合金件。对于渗漏相当严重的铸件,我们使用水玻璃渗入式堵漏剂堵漏,效果很好,现介绍如下。配方(重要比): 水玻璃(浓度为28°～32°波美)970 硫酸钡 1.5 氟硅酸钠 2.5 硫酸铝 12 二氧化锰 3.0 碳酸钠 6.0 配制先将水玻璃溶液和硫酸铝放在叶片式搅拌机中混和8～10分钟,待硫酸铝溶解后,加入硫酸钡和氟硅酸钠,再混和10～12分钟,待所有的氟硅酸钠及硫酸钡渗入胶状液后,再加入二氧化锰,混和3～5分
Casting workshop in my factory production, often have to test some of the pressure casting, in particular, some non-ferrous alloy castings, such as aluminum and copper alloy parts. For serious leakage of castings, we use water glass plugging plugging plugging effect is effective, are described below. Formulation (important ratio): Water glass (concentration 28 ° ~ 32 ° Baume) 970 Barium sulfate 1.5 Sodium fluorosilicate 2.5 Aluminum sulfate 12 Manganese dioxide 3.0 Sodium carbonate 6.0 Preparation First water glass solution and aluminum sulfate in the leaves Mixing mixer 8 to 10 minutes until the dissolution of aluminum sulfate, adding barium sulfate and sodium fluoride, and then mixed 10 to 12 minutes until all of the sodium fluorosilicate and barium sulfate into the colloidal solution, then add two Manganese oxide, mixed 3 to 5 minutes
