Yunqing Brand Practical Pickling Paste

One, Main Purposes:

Stainless steel pickling paste is used to remove rust, oxide scale, yellow and blue-black weld spots generated after welding, and other contaminants from various types of austenitic stainless steel parts, sheets, and their equipment surfaces. After treatment with the stainless steel pickling paste, the surface of the stainless steel becomes silver-white. The paste also passivates the surface, enhancing the stainless steel's corrosion resistance. Two, Outstanding Features: 1. This stainless steel pickling paste is a transparent substance. 2. The stainless steel pickling paste has strong ability to remove dirt. 3. This stainless steel pickling paste is particularly suitable for the partial or complete treatment of large workpieces and equipment. 4. This stainless steel pickling paste is suitable for situations where liquid immersion is not feasible, and it outperforms similar products on the market. Three, Applicable Scope: The stainless steel pickling paste is suitable for stainless steel chemical equipment such as 304, 316, 316L, and 321 models, as well as stainless steel printing and dyeing equipment, petrochemical equipment, beer equipment, and other stainless steel products factories. Four, Usage: Apply an appropriate amount of stainless steel pickling paste to the surface of the stainless steel to be treated, with a thickness of 1~2 millimeters. Leave it on for 5-30 minutes or longer, depending on the dirt, material of the plate, and processing requirements. It is recommended to scrub the surface several times during the treatment. After the surface oxide and rust are completely removed, rinse with clean water (lime water or alkaline water is preferred) to prevent rust from returning. For first-time use or those with limited experience, it is essential to test a small amount first to ensure satisfaction before using it in large quantities. Five, Precautions: 1. The stainless steel pickling paste is highly corrosive. Wear protective glasses and gloves during handling, use, and waste liquid disposal. 2. Do not come into contact with the eyes or mouth. If contact occurs, immediately rinse with clean water, then repeatedly rinse with a 1% baking soda solution (baking soda should be of analytical purity, and water should be distilled water). Finally, rinse thoroughly with clean cold water. In case of severe injuries, seek medical attention as it may be a case of strong acid burn. 3. Do not allow children to come into contact with or drink stainless steel pickling paste; If clear water appears, do not discard it. Shake well or mix thoroughly before use to ensure the product functions properly; 5. Stainless steel pickling paste is prone to volatilization and decomposition when heated. The higher the temperature, the faster the volatilization. Therefore, it is best to store it in a shaded and well-ventilated place. Make sure to place prominent signs indicating "Dangerous goods, do not touch." The pickling and passivation paste should be stored in a sealed container for long-term effectiveness. It is strictly prohibited to expose the paste to direct sunlight. Six, Waste liquid treatment: After neutralization with a neutralizing agent to a neutral pH of 7, it can be discharged without any harm. Seven, Packaging Specifications:
