高压水清砂和化学清理——国外精铸技术进展述评（9）
摘要
高压水清砂在国外已获得广泛应用
其特点是清理效果好
但缺点是一次性投资较大。为达到好的清理效果
必须要有结构合理的模组夹持装置
较高的水压以及模组与水枪之间的相对协调运动。化学清理在国外的主要进展是
开发出了一些新型化学清理剂以及对渣泥和废水的处理技术。
Abstract
High hydraulic pressure cleaning sand has been used widely at abroad
which has the features of good cleaning effects and high first-cost.To realize a good cleaning effects
it is ensured to the pattern-assemble holding device with rational structure
higher hydraulic pressure and relative coordinately moving between pattern-assemble and hydraulic device.Some new chemical cleaner and treatment technology for slag-mud and waste-water have been developed for chemical cleaning at abroad.
