Cold galvanized wire is in the plating bath by current unipolarity zinc plating on the wire appearance gradually

Cold galvanized wire is in the plating bath by current unipolarity zinc plating on the wire appearance gradually, production speed is slow, uniform coating, the thickness is usually 3 to 15 microns, with bright appearance, antirust and decorative performance.

It is made of high quality low carbon steel wire rod processing and into, is made of high quality low carbon steel wire after drawing molding, pickling derusting, high temperature annealing, hot dip galvanized, cooling process.

Product process: wire rod (raw materials) - big pull out - of - annealing - small - black annealed wire.

After processed into annealed wire can be on zinc plating processing shi.

Shi plating process:

Artifacts, oil, water washing, rust removing activation, washed, plating, water, hot water heating, air drying, rust-proof oil, packaging and finished products.

Note (reference)

1. The plating tank must be stainless steel or ceramic, enamel, plastics.

2. The surface oil and rust will seriously affect the quality of coating. Should be thoroughly remove oil and rust.

3. To give solution should be controlled temperature for 15 to 30 degrees.

4. Give the configuration of the plating solution: APCu - 8 a/B concentrate a (volume) + water two to three servings of fully stir (volume). APCu - 8 a/B concentrate a tap water (volume) + 1 to binary (volume) stir fully.

5. The plating finish is proportional to the base material finish.

6. Daily management of plating solution:

A. when shi plating solution can't meet should be added when using new liquor.

B. when plating solution failure, with plenty of water to dilute the emissions to the waste water pool.

7. Plating solution for plating loading capacity without strict requirements.

Storage quality

Store in shady and cool place airtight preservation. Eighteen months shelf life.

How to prevent rust wire, iron wire rust after how to deal with

Iron is put after a long time will rust, iron is easy to rust, lively out because of its chemical properties, colleagues also has a lot to do with external conditions. Water is one of the material of iron is easy to rust. Light there is water, however, will not make the iron rust, only when the oxygen dissolved in the water in the air, oxygen and iron in a water environment reaction, will generate something called iron oxide, which is rust. Rust is a kind of brownish red material, it is not as hard as iron, it is easy to fall off, after a piece of iron rust is complete, the volume can swell 8 times. If you don't remove the rust, the spongy rust particularly easy to absorb moisture, iron is rotten faster.

Antirust technology

1. The workpiece with 3-5% of the metal cleaner in 80-80 degrees for 10 to 15 minutes or mechanical cleaning, remove 0.5 1 minute is washed with tap water

2. If the workpiece rust is obviously the conventional acid cleaning derusting, in 3% hydrochloric acid solution soak 10 to 20 seconds to activation on the surface, and then rinse with water surface 0.5 1 minutes.

3. The workpiece into the configured in plating solution for 10-180 - s shi (visual artifacts required). Take out after plating good artifacts, 0.5 1.0 minutes, rinse with water in the passivation solution soak 5-10 minutes, take out 0.5 1.0 minutes, rinse with tap water. In the 80-95 degrees of hot water heating in 0.5 minutes, remove the artifacts in the air after natural volatile (or dry) water.

4. There can be no artifacts in derusting oil water soak 1 minute, after most of the oil drain, the packaging of the finished product.
