一、产品简介2000年以来,铝合金酸蚀技术以其去机械纹能力强、起砂快、铝耗低等诸多优点,在不到一年时间内,迅速取代碱蚀,成为目前铝合金氧化前处理的主流生产工艺。然而,自该技术推广之日起,铝合金表面发暗的问题一直困扰着生产厂家,也影响了产品档次。为了克服上述缺陷,大部分厂家都配备了碱蚀槽与中和槽。
I. Introduction Since 2000, aluminum alloy etching technology has many advantages such as strong resistance to mechanical pattern, quick recovery of sand, low aluminum consumption, rapid replacement of alkali corrosion in less than a year, Pre-treatment of the mainstream production technology. However, since the date of the technology promotion, the problem of darkening the surface of the aluminum alloy has plagued the manufacturers and affected the product quality. In order to overcome the above defects, most manufacturers are equipped with alkaline etching tank and neutralization tank.
