造型材料发气性是铸件生产过程中重要的检测项目之一。当高温金属液浇入铸型时,铸型受到热作用后,使铸型中的水分及其它附加物产生大量气体,这些气体不仅决定铸件是否会产生缺陷,而且也决定了铸件的表面质量。目前国内许多单位仍采用比较简易的发气性测定装置。测试时操作较麻烦,必须2～3人操作,操作者要有较高的测试技术水平,测试精度也较差。清华大学与邯郸市自动化仪表厂共同研制成功一种新的造型材料发气性测定仪。该测定仪可以测定各种型砂、芯砂、涂料及其它造型 Modeling material gas is one of the important test items in the casting production process. When high temperature molten metal is poured into the mold, the mold is subjected to heat and a large amount of gas is generated in the water and other addenda in the mold. These gases determine not only the defects of the castings but also the surface quality of the castings. At present, many units still use relatively simple gas measuring apparatus. Test operation is more troublesome, you must 2 to 3 people to operate, the operator must have a higher level of test technology, test accuracy is also poor. Tsinghua University and Handan Automation Instrument Factory jointly developed a new successful modeling material gas detector. The analyzer can measure a variety of sand, core sand, paint and other shapes
