酸洗鈍化時(shí)應(yīng)該注意哪些方面？
、酸洗鈍化處理，首次操作應(yīng)先在小部件局部面上或類(lèi)似的材料上作試驗(yàn)。
, pickling and passivation, for the first time, test on the local parts of the small parts or similar materials should be done first.
、 操作人員在操作時(shí)，必須穿好耐酸服，帶好手套，口罩與防護(hù)眼罩。在容器內(nèi)酸洗，必須帶上檢查合格的防毒面具，并在專(zhuān)人監(jiān)護(hù)下進(jìn)行。
, operators must wear acid proof clothing, gloves, masks and protective goggles while operating. Acid pickling in containers must be carried out with qualified gas masks and conducted under special guardianship.
、 酸洗過(guò)程中，操作人員必須認(rèn)真仔細(xì)，及時(shí)觀察，防止容器表面腐蝕過(guò)重。對(duì)碳鋼零部件應(yīng)采取有效措施，防止遭到腐蝕。
, during the pickling process, operators must be careful and careful to observe in time to prevent excessive surface corrosion. Effective measures should be taken for carbon steel parts to prevent corrosion.
、 酸洗后不銹鋼表面不得有明顯的腐蝕痕跡，不得有顏色不均勻的斑紋，焊縫及熱加工表面不得有氧化色。
. After pickling, the stainless steel surface must not have obvious corrosion marks, and there should be no uneven markings.
、配液時(shí)應(yīng)將水按比例放入耐酸容器中，然后再按比例緩慢加酸，防止倒酸速度過(guò)快引起飛濺傷人。
. When mixing the liquid, the water should be put proportionally into the acid proof container, then slowly add acid to the ratio, so as to prevent the acid falling too fast and cause splashing and hurting people.
、有防腐要求的不銹鋼零部件按圖樣要求進(jìn)行熱處理后，做酸洗鈍化處理。
. Stainless steel parts with anticorrosion requirements are treated by heat treatment after drawing, and pickled and passivated.
、酸洗鈍化配方及操作、濃度、體積比、液體溫度和操作時(shí)間可根據(jù)情況允許做小量適當(dāng)?shù)恼{(diào)整。酸洗鈍化液可重復(fù)使用，但必須保證適當(dāng)?shù)臐舛群腕w積比。
, pickling and passivation formula and operation, concentration, volume ratio, liquid temperature and operating time can be adjusted according to circumstances. The pickling and passivation solution can be used repeatedly, but the proper concentration and volume ratio must be ensured.
