本技术涉及一种蚀刻液存储罐限位装置,属于蚀刻液生产设备
技术介绍
蚀刻(etching)是将材料使用化学反应或物理撞击作用而移除的技术。蚀刻技术可以分为湿蚀刻(wetetching)和干蚀刻(dryetching)两类。最早可用来制造铜版、锌版等印刷凹凸版,也广泛地被使用于减轻重量(WeightReduction)仪器镶板,铭牌及传统加工法难以加工之薄形工件等的加工;经过不断改良和工艺设备发展,亦可以用于航空、机械、化学工业中电子薄片零件精密蚀刻产品的加工,特别在半导体制程上,蚀刻更是不可或缺的技术。蚀刻液是一种铜版、锌版等印刷凹凸版雕刻用原料,通过侵蚀材料的特性来进行雕刻的一种液体。由于蚀刻液属于化学原料,因此在对每一种类蚀刻液进行储存时应避免进入杂质以及其他化学成分。蚀刻液通常存储于存储罐内,在向存储罐内灌入蚀刻液时应保持内部的清洁,避免存储罐内壁上附着有其他化学成分的材料残渣,因此需要对存储罐进行清洗。而现有的清洗都是通过工人手持清洗喷管插入到存储罐内进行喷淋清洗,清洗后的水则存留在存储罐内无法及时排出,只能等基本清洗完毕 ...
