電鍍工作中怎樣控制化學(xué)鍍鎳層含磷量?化學(xué)鍍鎳層中的磷含量多少是對電鍍加工后的鎳鍍層的電阻率，以及防腐性能都有影響，含磷量在電鍍加工生產(chǎn)中是一個衡量產(chǎn)品性能的重要的指標(biāo)。一般我們區(qū)分為低磷，中磷，高磷鍍層，高磷化學(xué)鎳在鋼鐵、鋁合金、銅等五金電鍍件中應(yīng)較多，低磷化學(xué)鎳在塑料電鍍件應(yīng)用或底鍍層中應(yīng)用較多。 </p> <p> 高磷配方的磷含量是10-13%左右，所以操作中基本在這個范圍內(nèi)浮動，不會超過很多。 </p> <p> 在電鍍加工為了獲得穩(wěn)定的鍍速與鍍層質(zhì)量，濃度，溫度，PH都是固定在一個較小的范圍內(nèi)，通過調(diào)整化學(xué)鍍鎳液的成分與含量控制化學(xué)鍍鎳層含磷量，適當(dāng)多加一些蘋果酸就能在一定范圍內(nèi)提高化學(xué)鎳鍍層的磷含量。 </p> <p> 同樣，如果電鍍液的配方成分含量控制在固定程度內(nèi)不變，通過改變電鍍工作相關(guān)的工作參數(shù)調(diào)整電鍍層的磷含量。 </p> <p> 在酸性中磷化學(xué)鎳的鍍液配方，我們可以通過提高鍍液的溫度，鎳離子的濃度，PH值參數(shù)，增加或降低磷含量。 </p> <p> <br /> </p> <p> <br />
