前言水是世界上人们最熟悉最重要媒质之一、长期以来这种媒质只局限于作饮用,洗涤、灌溉等。只是近年来,人们对水射流在材料清洗、穿透、破碎和切割方面运用的兴趣才增大了。如今已引起各方面的兴趣。诸如纸、木材、岩石、煤、混凝土、甚至金属都已用高压射流进行穿透、破碎或切割。管子清洗,表面去垢、轮船清洗、剥离树皮,清洗容器,去防护层和去漆、除锈用此法也取得一定效果。 Foreword Water is one of the most important and familiar media in the world and has long been limited to drinking, washing, and irrigation. It is only in recent years that interest in using waterjets for material cleaning, penetration, crushing and cutting has increased. Now it has aroused the interest of all parties. Materials such as paper, wood, rock, coal, concrete, and even metals have been penetrated, crushed or cut with high pressure jets. Pipe cleaning, surface decontamination, ship cleaning, stripping the bark, cleaning containers, to the protective layer and to paint, rust with this method also achieved some results.
