Description

Modeling material volatile component collection device for casting Technical Field The application belongs to the technical field of molding materials in foundry industry, and particularly relates to a molding material volatile component collecting device for casting. Background In the field of casting technology, materials used to make casting molds (including sand cores, paints, etc.) are collectively referred to as molding materials. The molding material occupies an indispensable position in casting production, and the quality of the molding material directly influences the quality, production efficiency, production cost and environmental pollution in the casting production process. The control of the amount and chemical composition of volatile components of molding materials is an important matter for evaluating environmental pollution of molding materials. At present, a molding material gas-forming tester is used for detecting the gas-forming amount and the gas-forming speed of a molding material in the technical field of casting detection. The detection technology field also has mature technology for gas component analysis, such as chemical analysis, chromatography, infrared spectrometry, etc. However, despite the continued advances in inspection technology, the foundry industry is still challenged in terms of collection of volatile components of molding materials. The existing collection equipment and method often have difficulty in avoiding the mixing of air (nitrogen, oxygen, carbon dioxide and other various components) or can not collect a sufficient volume of volatile gas to be detected due to insufficient volatilization amount of individual volatile samples, in this case, the volatile samples usually need to be replaced, but air components are inevitably introduced in the process of opening the volatile space to replace the samples, which clearly increases the difficulty of analysis of volatile components of molding materials. Therefore, the efficient and accurate molding material volatile component collecting device is developed, and has important significance for improving the accuracy of environmental pollution assessment in the casting industry.
