A major one occurs when the foam pattern is evaporated by pouring molten metal. The pyrolysis of poly (methyl methacrylate) foam patterns by molten metal produce methyl methacrylate, carbon monoxide, carbon dioxide and unburned hydrocarbons, and possibly small amounts of benzene. These volatile pyrolysis gases are harmful and released during metal casting using foam patterns. Consequently, caution must be exercised when handling these gases. Handling and disposal guidelines of these gases should also be developed at each site of use for the preservation of natural environment. This paper reviews some analysis data on the pyrolysis gases of foam patterns and their countermeasures in the evaporative pattern casting process.}, pages = {841--846}, title = {消失模型鋳造法における熱分解ガスの処理}, volume = {69}, year = {1997} }
