Fluorine-free ammonium tetrad sand front treatment agents and their use and recovery system, fluorine-free ammonium tetrad sand front treatment agents, including the following components: sodium hydroxide 30 50g/L, sodium chloride 100 200 g/L, sodium thiosulfate 1.5 3.5g/L, surfactant 1.5 3.5g/L, sorbitol 1.5 3.5g/L, sodium gluconate 1.5 3.5g/L, the remaining amount of water. The reagent recovery system comprises a four-in-one tank and a non-flow water washing tank subsystem, the non-flow water washing tank subsystem is arranged in series in reverse phase as a whole, and a water supply outlet is arranged at the beginning of the water flow direction, and the outlet of the terminal is connected in series with the four-in-one tank. The invention provides a fluorine-free ammonium-free quadruple sand front treatment agent, which has the functions of degreasing, acid etching, alkali etching, neutralizing four troughs, effectively solves the fluorine and ammonium pollution of aluminium alloy anodizing pretreatment. In addition, by using the above-mentioned fluorine-free ammonium-free quadruple sand front treatment agent recovery system, the enterprise pollution control can be greatly reduced through the limited use of the agent and the recovery of the agent. Quantity, reduce production costs, improve efficiency.
【技术实现步骤摘要】
无氟无铵四合一砂面前处理药剂及其使用和药剂回收系统
本专利技术涉及铝材表面处理
,尤其涉及无氟无铵四合一砂面前处理药剂及其使用和药剂回收系统。
技术介绍
铝合金砂面前处理工艺主要分为碱蚀、酸蚀和机械喷砂三大类。传统机械喷砂工艺已大规模应用20多年,虽然具有铝耗低、药耗低等优点,但需要配置专门的喷砂车间,喷砂后再转运至氧化车间,效率低,易擦伤表面形成废品。受铝材形状限制,喷砂表面很难均匀,着色后不均匀被放大,废品率直线上升。申请人的在先申请(200510101420.X)铝合金光亮酸蚀技术,公开了对既有酸蚀工艺的改进,按下述方式安排反应槽:表1铝合金光亮酸蚀技术槽位布置(中国专利200510101420.X)各槽功能为:1#除油脱蜡槽:主要功能是在常温下除油、脱蜡、脱自然氧化膜,并兼备一定程度的低温抛光能力;3#增亮酸蚀槽:普通酸蚀槽的改进型,具备普通酸蚀槽的起砂快、去机械纹能力强、铝耗低和砂粒均匀等优点;4#砂面抛光槽:清除酸蚀灰和砂面材低温抛光。尽管铝材从3#增亮酸蚀槽取出后,大部分酸蚀灰已被清除,但少量残存灰依然十分顽固,常规方法很难清除;除了酸蚀灰外, ...
