Mechanism Disquisition of De-rusting By Ultra-high Pressure Waterjet

摘要

Water often leads rust, it can also remove rust. The paper mainly discusses the mechanism of de-rusting by ultra-high pressure (short for u.h.p.)pure water as high as 200 to 250Mpa. It adopts u.h.p rotating waterjet, automatic wall-climbing and rust dregs vac sorbing and recycling. Mechanism of water-jtetting de-rusting is to scour and strip the rusty scale of the converted steel surface by normal hitting power and edge angle of waterjet and twisting force of rotating. The testing proves the mechanism equation.
