Foundry Mold Treating Compositions And Methods Of Making Same
US Patent:
4289803, Sep 15, 1981
Filed:
Jun 9, 1980
Appl. No.:
6/158065
Inventors:
Wayne F. Wales - Clifton Park NY
James J. Frawley - Loudonville NY
James J. Frawley - Loudonville NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
B28B 738
B29C 104
B29C 104
US Classification:
427134
Abstract:
Phosphosilicate compositions are disclosed for treating foundry molds and like products to enhance mold strength and refractoriness. The phosphosilicates, characterized more specifically as silicyl metaphosphates, may be used in combination with select refractory aggregates and other additives to form mold surface treating compositions, or may be combined directly with foundry sand or other comminuted refractory material for compacting into a mold form.
Method For Producing Hybrid Binder For Ceramic Molds
US Patent:
3961968, Jun 8, 1976
Filed:
Mar 17, 1975
Appl. No.:
5/559191
Inventors:
Wayne F. Wales - Elnora NY
Assignee:
Waukesha Foundry Company, Inc. - Waukesha WI
International Classification:
B28B 734
B01J 1300
B01J 1300
US Classification:
106 3835
Abstract:
Methods of preparing Hybrid Silicate Binders are shown by admixing the following materials: 1. a basic or acidic colloidal silica sol suspended in water or glycol ether; 2. an organic silicate, such as ethyl silicate, hydrolyzed with water; 3. a mineral acid of sufficient quantity to produce a final binder having a pH of 1 to 4; and 4. the hybrid binder contains silica sol and organic silicates such that the ratio of weight contribution of SiO. sub. 2 from organic compounds to weight contribution of SiO. sub. 2 from colloidal silica sol is in the range between 0. 09 to. 9, in the final binder. That is, ##EQU1## The final binder preferably contains about 18%-21% SiO. sub. 2. If basic silica sol is used it must be added to a mixture of the other ingredients. The preferred binder has a shelf-life exceeding nine months, it can be chemically polymerized or air-set and provides high binder strength and refractoriness.
