| description | The invention relates to a stainless steel pickling and passivating liquid. The stainless steel pickling and passivating liquid is manufactured by taking nitric acid (HNO3) and hydrofluoric acid (HF) as main raw materials, then adding a proper amount of water and mixing. The stainless steel pickling and passivating liquid can effectively clean such dirt as rust, oil stain and weld spots on a stainless steel surface, so that the stainless steel material can obtain a uniform and consistent silvery white surface, a layer of thin and compact passivation film is formed, the corrosion resistance of stainless steel is well promoted, and accordingly, extensive application is achieved. The stainless steel pickling and passivating liquid contains 15% of nitric acid (HNO3), 10% of hydrofluoric acid (HF) and 75% of water (H2O) by volume.
本发明涉及种不锈钢酸洗钝化液，是以硝酸（HNO）、氢氟酸（HF）为主要原料，再加入适量的水，经混合后制得的液体。这种不锈钢酸洗钝化液，能够有效清除不锈钢表面的腐锈、油污、焊斑等污垢，使不锈钢材料获得均匀致的银白色表面，并形成层薄而致密的钝化膜，对不锈钢的防腐蚀能力有很好的促进作用，得到较为广泛的应用。本发明不锈钢酸洗钝化液的体积含量为硝酸（HNO）15%、氢氟酸（HF） |
