42CrMo Steel Auto Harmonic balancer puller Silica sol casting.
In silica sol casting, the pattern is made by wax and other easily soluble materials, and several layers of refractory materials are coated on the pattern to complete the shell. The pattern is formed by melting and casting, and then it is subjected to high temperature baking to achieve better application effects. Casting belongs to the category of near-net shape technology, which can produce high-quality precision castings and is widely used in industrial production.
Compared with the traditional investment casting process, the silica sol ceramic precision casting process has the characteristics of short production cycle, high precision, good surface quality and collapsibility, and is especially suitable for rapid manufacturing in combination with rapid prototyping technology (RP). Metal parts.
In order to improve the quality of investment casting castings, it is necessary to control the preparation process of the shell preparation process such as the preparation of silica sol-ethyl silicate coating, coating operation and drying.
Silica sol is a new type of binder used in investment casting. Compared with ethyl silicate and water glass, it has the advantages of easy availability of raw materials, simple process, non-toxic, high shell strength and good casting finish. Therefore, The application is becoming more and more extensive. The silica sol prepared in the early stage, such as KC binder and APK 1 binder, has a silica content of only 10-13%, and the resulting shell has low strength and can only be stored for several weeks to several months. It has not been promoted and applied in the industrial production of silica sol. BIRD, BECHTOLD, RULE and others used hydrogen-type cation exchange resin to treat dilute water glass to obtain acidic mother liquor. Concentrate by boiling under reduced pressure to obtain a high-concentration and stable commercial product.
