Stainless steel pickling passivation solution is a combination of domestic and foreign technologies, with inorganic acid, oxidant as the main agent, adding hydroxy acid compound, high-efficiency corrosion inhibitor and fog inhibitor. The stainless steel pickling passivation solution is colorless and transparent, the smell can be operated indoors and outdoors, brushing, spraying and soaking can be used, the soaking effect is excellent, the operation process is simple, the construction is convenient, time-saving and labor-saving, the treated stainless steel The surface is smooth and clean, the stability is strong, the corrosion resistance is obviously improved, the service life of the equipment is prolonged, and the added value of the product is increased.
Technical indicators:
Appearance Colorless transparent liquid
Physical stability No crystals are precipitated
PH value ≤2.5
water soluble
Instructions
Stainless steel small parts can be soaked in a container and used in the original solution. The recommended soaking time is 5-15 minutes in summer and 20-30 minutes in winter. Users can control the time according to the degree of color they need. (If the oxide layer is thick and there is a lot of dirt, the time can be appropriately extended), just rinse it with clean water. For larger equipment, in order to ensure the quality of cleaning and passivation and save passivation materials, a pump can be used for circulating spray. method of drenching. (Note: The final water rinse must be clean to ensure that there is no residual pickling passivation solution), the surface of the treated stainless steel equipment is as smooth as new, and the original color of the stainless steel is restored.
Scope of application: Removal of tan oxides (rust) produced after high temperature processing such as welding, hammering, and damage to related stainless steel components such as petrochemicals, marine pipelines, pharmaceuticals, papermaking, food, and Class I-III pressure vessels. , make it bright and shiny, and at the same time form a layer of oxide film to achieve the purpose of passivation, with the dual effect of two steps of pickling and passivation.
It is widely used in the removal of rust, welding spots, oil stains, black and yellow oxide scale produced in the process of forming, assembling and welding, and at the same time, it can fully passivate the stainless steel workpiece, which greatly improves the corrosion resistance of the stainless steel workpiece. It truly achieves the effect of pickling and passivation in one. This product has been tested for more than 1000 hours of salt spray, and has passed the blue dot test standard of the testing department.
Precautions
(1) Cleaning tank: When the working tank is made of acid-resistant plastic tank, glass fiber reinforced plastic tank and low carbon steel, PVC plastic lining is required.
(2) Addition and maintenance of bath liquid: regularly clean the sundries and residues in the bath (to prevent sundries and residues from reducing the concentration of the bath liquid). When the cleaning ability of the working fluid decreases, it can be resumed by adding new fluid (the pH value should be controlled within 2, and some new fluid should be added in time when the pH value is greater than 2).
(3) The waste liquid removes the sediment and floating objects, and then adds new liquid to adjust for continued use, or adjusts the pH value, separates the sediment, and discharges the waste liquid according to the standard.
(4) Equipped with protective equipment such as rubber gloves and goggles during operation; the skin should not come into contact with this product, and it should be washed with water if it is accidentally touched.
storage and transportation
When storing, loading and unloading of stainless steel pickling passivation solution, refer to SH/TO164. The higher temperature should not exceed 75℃; if stored for a long time, the higher temperature should not exceed 45℃. This product has strong acidity and strong corrosiveness, so attention should be paid to safety in storage and transportation. Beware of freezing in winter.
This product can be used at room temperature as a four-in-one surface treatment agent for degreasing, rust removal, phosphating, and passivation of steel workpieces, cleaning, brushing, spraying, and soaking. It can be applied to various mechanical equipment and large steel workpieces. .
main feature
1. The preparation and addition of this product use the same preparation alone, which is simple and convenient.
2. This product is suitable for degreasing, rust removal, rust prevention, phosphating and passivation on the surface of oil stained and rusted workpieces. It does not need to be rinsed with water after treatment, and it does not need to be discharged frequently, saving processes and production costs.
3. Less investment in equipment, wide application, simple operation and light labor intensity.
4. This product has no pollution to the environment, no harm to the human body, and low comprehensive cost.
Instructions
1. According to the size of the workpiece to be processed, the small workpiece can be treated by immersion. Brushing or spraying requires the surface of the part to be dry, and be careful not to miss the coating. It is recommended to take corresponding measures for gaps, blind holes, etc.
2. The processed workpiece should avoid direct contact with hands or other contamination as much as possible, so as not to affect the rust prevention effect. If conditions permit, the parts can be packaged to prolong the rust prevention time.
Daily maintenance and management of working fluid
Frequent abductions before and after each shift or during processing.
1. Oil stains and debris on the surface of the tank liquid and sediment at the bottom of the tank.
2. When the color of the bath liquid turns black and is too dirty to affect the effect, the bath liquid should be discarded and reconstituted, otherwise the dirt will adhere to the workpiece for a second time, causing great hidden dangers to the quality. Do not use the "circle" method and wait until the workpiece is dry before wiping with a dry cloth.
3. This product is packed in plastic barrels, 25kg per barrel.
