Study on A New Inorganic Binder for Fabricating Casting Mold and Core
After reviewing deficiencies of organic foundry binders such as furan, phenolic resin, the author in this paper introduces a new inorganic binder which is colorless and tasteless and does not burn when contacted with liquid metal and has no smoke and other harmful materials to emit into atmosphere. In the paper, the hardening characteristic and properties of inorganic binder nobake and heat hardened sand such as tensile strength, humidity resistance, gas forming and collapsibility are investigated. Foundry trials were carried out to prove that the new binder meets practical requirements.
