DunHua 365

Stainless steel pickling passivation solution

First, product overview:

DH-365 is a world-leading research and development technology. Stainless steel pickling and passivation are combined into one. It can remove grease, rust, weld spot, oxide layer, free iron and other dirt on the surface of the workpiece while passivating, and the treated surface becomes uniform silver-white. At the same time, high-efficiency corrosion inhibitor and fog inhibitor are added to prevent metal from over-corrosion and over-corrosion. Hydrogen embrittlement and acid mist suppression; corrosion resistance after passivation increased to 15 to 50 times, the highest through salt spray test 1500H; suitable for 200, 300 series stainless steel parts, plates and equipment acid pickling passivation treatment.

Second, product advantages:

1. Suitable for pickling and passivation of all stainless steel products of SUS200 and SUS300 series.

2. Remove all kinds of stainless steel parts, plates and equipment surface rust, oxide skin, yellow, blue, black spot and other contaminants after welding; the treated surface is uniform silver-white, with excellent decorative effect; has excellent rust and corrosion resistance.

1. Super cleaning and decontamination effect, fast rust-dissolving, chemical weld spot oxide performance; simple operation, easy to use, without complex equipment.

3. Recommended uses:

1. Widely used in aerospace, mobile communications, automotive accessories, precision hardware, medical equipment, food machinery, fasteners and other industries.

2. For stainless steel passivation by acid pickling, remove all kinds of dirt, such as oil, rust, oxide, weld spot, etc., after treatment, the surface becomes uniform silver-white.

Fourth, environmental protection performance:

1. Passivation solution does not contain harmful substances, which conforms to RoHS and REACH environmental protection standards. It has passed the tests of SGS and FDA.

2. Centralized treatment of wastewater and neutralization of alkaline limewater or sodium hydroxide make the PH value close to 7 and then discharged, which has no impact on the environment.

Fifth, packaging and storage:

1. This product is packed according to SH 0164-92, in plastic drums, 25/ drums.

2. Store in a cool and dry place with a storage temperature not exceeding 45 C. Avoid direct sunlight for 12 months.
