Shelling mould casting side plate

According to the manufacturer of laminated sand, additives are compounds that help in the production and manufacturing process to improve the production process and product characteristics. In terms of categories, food grade refers to small amounts of compounds dispersed in raw materials that are not significantly harmful to the raw material structure to improve the production characteristics and commodity properties of certain raw materials.

Additives are also used in the production and manufacture of laminated sand casting pump bodies to improve their properties. Uroto products are the basic curing agents for clad sands and are added at 5-20% of the epoxy resin. Some companies have designed and developed unique curing agents to achieve special provisions such as anti-fading shells and rapid aggregation. For calcium stearate, polymethacrylate milling ammonium, etc., the lubricant serves to avoid agglomeration and to improve the flow and moldability of the laminated sand. In order to avoid the fading shell condition of the laminated sand throughout the application process, the lubricating fluid should try to use the goods with weak melting point.

Laminated sand casting process warming temperature 200-300 ℃, curing time 30-150s, sand injection pressure 0.15-0.60 MPa. shandong laminated sand has a simple shape and good fluidity, you can choose a stronger injection pressure, thinner sand core can choose a stronger warming temperature, lower warming temperature can be appropriate to improve the curing time, etc. Phenolic resin is used for Shandong clad sand.
