Non - Toxic Glyceryl Triacetate Metal Foundry Sector For Cellulose Diacetate Plasticizer

Mold Hardener Casting use Sodium silicate organic ester curing agent

Use and features:

  This product is used in foundry production, a total of 3 varieties of self hardening characteristics. Harmless, non-toxic, sand from the characteristics of hard high strength. Adding a small amount of organic fat in the water glass, becomes at room temperature, since the hard sand to sand in the model, since the hard demoulding without drying. Verification in different parts of the country iron non-ferrous metal production and other aspects of the large and medium-sized enterprises, with high dimension accuracy of castings, made less gas, small machining allowance, good collapsibility, production and low energy consumption.

Hardening mechanism:

  General ester hardening water glass sand compressive strength of 1.5-3Mpa.
Organic ester combined with water glass, water glass in the alkaline medium, organic ester was hydrolyzed into acid and alcohol. Organic acid and water glass reaction precipitated silica, but combined with each other to form a mesh silica gel, gradually hardening. At this time due to sand were enclosed in mesh structure, and build sand strength.
