医药企业设备 管道酸洗 钝化

1、酸洗钝化处理,首次操作应先在小部件局部面上或类似的材料上作试验。

1, pickling and passivation, for the first time, test on the local parts of the small parts or similar materials should be done first.

2、 操作人员在操作时,必须穿好耐酸服,带好手套,口罩与防护眼罩。在容器内酸洗,必须带上检查合格的防毒面具,并在专人监护下进行。

2, 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.

3、 酸洗过程中,操作人员必须认真仔细,及时观察,防止容器表面腐蚀过重。对碳钢零部件应采取有效措施,防止遭到腐蚀。

3, 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。

4、 酸洗后不锈钢表面不得有明显的腐蚀痕迹,不得有颜色不均匀的斑纹,焊缝及热加工表面不得有氧化色。

4。 After pickling, the stainless steel surface must not have obvious corrosion marks, and there should be no uneven markings。

5、配液时应将水按比例放入耐酸容器中,然后再按比例缓慢加酸,防止倒酸速度过快引起飞溅伤人。

5. 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.

6 、有防腐要求的不锈钢零部件按图样要求进行热处理后,做酸洗钝化处理。

6. Stainless steel parts with anticorrosion requirements are treated by heat treatment after drawing, and pickled and passivated.

7、酸洗钝化配方及操作、浓度、体积比、液体温度和操作时间可根据情况允许做小量适当的调整。酸洗钝化液可重复使用,但必须保证适当的浓度和体积比。

7, 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.
