Three is to do a good job of galvanized silk product production site clean and tidy, in accordance with the scientific method of operation to operate the production, the operator should wear the required dress. If it is hot dip galvanized wire products, we must do a good job of passivation treatment, will be able to effectively prevent discoloration, prolong the method of discoloration, can solve the problem of discoloration.

Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized layer.

A pet carrier can be used as an indoor and outdoor pet house. The dog cage is equipped with a fixed food basin and drinking water, and the foot plate pet cage rubber pad has bayonets on four sides to be collated. According to the cage size can be splicing, cutting, disassembly is convenient, easy to clean, can solve the puppy in the ordinary cage foot clamping problem, prevent the puppy in the development of adverse reactions. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet that does not hold its feet or pinch its feet.

Maintenance is indispensable in the use of galvanized wire. Large coils of galvanized silk should be coated with oil, fiber core immersion oil, oil is required to protect the fiber core is not rotten, not rust, wire moisture fiber, and from the internal lubrication wire rope. Surface coating so that all wire rope strands in the surface, are evenly coated with a layer of rust-proof lubrication grease, which for friction lifting and mineral water large mine rope, to be coated with grinding and water-resistant black oil grease. Coated with red oil with strong film and good rust resistance, it is required to have a thin oil layer, which is easy to keep clean during operation.

Stainless steel blade barbed rope material is produced according to stainless steel plate and stainless steel wire, as a whole have achieved the purpose of high quality anticorrosion. So how long can stainless steel blade thorn rope be used?

After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.

Some customers pay more attention to the quality problem, so they pay more attention to the service life. The barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.

The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.

1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.
