防銹鋁板電鍍前的處理方法有哪些?

來源:http://www.kangyanghua.com/ 發(fā)布時(shí)間:2021-07-12

防銹鋁板進(jìn)行電鍍時(shí),因?yàn)槭艿戒X的特殊性能的影響,需要有特殊的前處理,而這些前處理因不同防銹鋁板和不同制件狀況而需要有所調(diào)整,不能簡單沿用通用工藝.因而,對于從事防銹鋁板上電鍍的工作者,有時(shí)需要做防銹鋁板電鍍前處理的實(shí)驗(yàn).
Due to the influence of the special properties of aluminum, special pretreatment is needed for the electroplating of antirust aluminum plate. These pretreatment needs to be adjusted for different antirust aluminum plate and different parts, so the general process can not be simply used. Therefore, for the workers engaged in the electroplating of antirust aluminum plate, it is sometimes necessary to do the experiment of pretreatment of antirust aluminum plate
進(jìn)行防銹鋁板電鍍前的處理方案的實(shí)驗(yàn),也是系統(tǒng)化的比照實(shí)驗(yàn),需要對樣件進(jìn)行不同選定前處理工藝的處理,然后進(jìn)行相同的電鍍加工,再檢測其結(jié)合力.這種比照實(shí)驗(yàn)的要點(diǎn)是要保證除了差別工藝點(diǎn)外,其他流程都是同一條件的,否則就沒有了可比性而無法做出評價(jià).
The experiment of pre-treatment scheme for antirust aluminum plate electroplating is also a systematic comparative experiment. The sample needs to be treated with different pre-treatment processes, and then the same electroplating process is carried out, and then its adhesion is tested. The key point of this comparative experiment is to ensure that other processes are under the same conditions except for different process points, otherwise there will be no comparability and no evaluation


前處理工藝的選型和改進(jìn)的辦法的設(shè)計(jì).鋁圓片電鍍前處理包括除油、酸蝕、化學(xué)鍍或置換鍍、預(yù)鍍等四個(gè)重要工序.其中較為關(guān)鍵是化學(xué)鍍或置換鍍,因而,常常要做的實(shí)驗(yàn)都集中在這道工序上.
The pre-treatment of aluminum wafer electroplating includes four important processes: degreasing, acid etching, electroless plating or displacement plating, and pre plating. Among them, electroless plating or displacement plating is the most important one. Therefore, the experiments are often focused on this process
當(dāng)然不同的鋁材和不同的加工辦法對前處理有不同的要求,比方壓鑄鋁件與軋制鋁件的前處理就有很大區(qū)別,而即使是同一種加工方法,不同的鋁材也有不同的前處理工藝,比方鋁的含銅量的多少就直接影響其鍍層的結(jié)合力.
Of course, different aluminum materials and different processing methods have different requirements for pretreatment. For example, the pretreatment of die casting aluminum parts and rolled aluminum parts is very different. Even if it is the same processing method, different aluminum materials also have different pretreatment processes. For example, the copper content of aluminum directly affects the adhesion of the coating
