Post time: 14-04-23Hot dip galvanizing is also called hot dip zinc and hot dip galvanizing: is an effective way of metal corrosion, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel parts is attached with zinc layer, so as to play the purpose of anticorrosion. Hot dip galvanizing process: finished product pickling – washing – adding bath aid – drying – hanging plating – cooling – drug – cleaning – grinding – hot dip galvanizing completion. Hot dip galvanizing is developed from the older method of hot dip galvanizing. It has a history of 140 years since it was applied to industry in France in 1836. However, the hot dip galvanizing industry has been developed on a large scale in the past 30 years with the rapid development of hot dip galvanizing wire.

Zinc layer structure: The structure of zinc layer includes grain size, grain shape and the combination of zinc layer and substrate, etc., which has a certain impact on corrosion resistance. In general, the finer the grain size, the denser the structure, and the better the corrosion resistance.

1. Zinc pot operators must stick to their posts
The guide frame of spray hook net wholesale is composed of guide beam and park core pile, their interval distance is about 3 meters, the spacing of guide beam should be about 1 cm higher than the wall. When installing the guide beam, its position should be far away from the net, and the surround-pile should not be expanded, which will make the surround-pile sink or change its shape.
Post time: 25-05-22- The spring operating at high temperature requires that it can adhere to the elastic limit and good creep resistance at high temperature. In addition, the forming process and heat treatment process of spring steel wire should also be considered. Cold drawn spring steel wire and oil quenched tempered spring steel wire are directly around the supply of steel wire spring, spring forming after the elimination of stress directly used.
3. Zinc layer structure: The structure of zinc layer includes grain size, grain shape and the combination of zinc layer and substrate, etc., which has a certain impact on corrosion resistance. In general, the finer the grain size, the denser the structure, and the better the corrosion resistance.
- 2, galvanized welding mesh away from acid and alkali corrosion effect of acid and alkali is electric welding mesh. If the electric welding mesh is accidentally stained with acid and alkali, it should be immediately washed with clean water, and then dried with dry cotton cloth.
Galvanized wire in acid, alkali, sodium chloride aqueous solution of poor corrosion resistance, in the atmosphere containing carbon dioxide and hydrogen sulfide, as well as Marine atmosphere is not corrosion resistance. In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.
Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. Material: low carbon steel wire, stainless steel wire, PVC wire, copper wire knitting: straight twist, reverse twist, two-way twist, first after plating, first plating after knitting, and hot dip galvanized, zinc aluminum alloy, galvanizing, PVC coated, etc. Features: Solid structure, flat surface, with good corrosion resistance, oxidation resistance and other characteristics. Uses: Used for raising chickens, ducks, geese, rabbits and zoo fences, mechanical equipment protection, highway guardrail, etc.
In general, the hardness of a metal is often considered to be the resistance of the material to plastic deformation, scratches, wear, or cutting. In the debugging of zinc wire dipping distance, keep the original speed unchanged, according to the time of dipping zinc, the diameter of steel wire, and then estimate the dipping distance. By adjusting the zinc immersion distance, the zinc immersion time of steel wire of various specifications is shortened by 5s on average compared with that before debugging, so that the zinc consumption per ton of steel wire is reduced from 61kg to 59.4kg.
- The drawing process of waste product drawing process has a great influence on product function. Generally, large total surface reduction rate (see area reduction rate) and small pass surface reduction rate (about ≤23%) are selected to ensure the tolerance of products. About high strength spring steel wire, the exit temperature of each pass steel wire should be controlled when drawing below 150℃, to prevent the steel wire from changing cracks due to strain aging, which is the main disadvantage of steel wire obsoletion.
- 5. Dry it with a towel.
Post time: 30-06-22Cattle fence network in outdoor use for a long time will inevitably appear rusty corrosion, this time the use of cattle fence network life depends on the maintenance of the product is not in place, we all know that cattle fence network if a long time exposed to the harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
Post time: 27-02-23The tensile strength of cold drawn spring steel wire is slightly higher than that of oil tempered steel wire. The large specification of cold drawn steel wire elastic force is too large, winding the spring is very difficult, so the cold drawn spring steel wire application specification is generally less than 8.0mm, oil quenching tempered steel wire application specification is generally less than 13.0mm. In fact, the diameter of 13.0mm spring is used to light tension spring steel wire, cold drawing wound made into shape and then quenched and tempered. Steel wire with diameter above 15.0mm is mostly made by heating winding process.
- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
Cattle net in the outdoor use of a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know that cattle net if long exposure to harsh environment, the service life will be greatly reduced.
