Automotive industries also rely on M4 hex head bolts for various applications, such as assembling engines, chassis, and body components
In addition, before the wire enters the zinc liquid, a layer of insulation material containing zinc oxide reducing agent can reduce the heat loss and zinc ash floating. When the zinc solution contains 0.002%-0.005% aluminum, the brightness of the zinc layer can be increased obviously, and excessive zinc ash can be prevented from oxidation on the surface of the zinc solution.
1. Electroplating process control
- The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tightly bound with a very strong transparent plastic bag. The outer layer of coated iron wire is wrapped with white braided cloth, and the outer layer of galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process. One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
- A remarkable characteristic of stainless steel wire rope is its inherent corrosion resistance to concentrated nitric acid and dilute nitric acid, which makes it easy to be distinguished from most other metals or alloys. But high carbon 420 and 440 steel in the nitric acid point test is slightly corroded, non-ferrous metal encountered concentrated nitric acid is immediately corroded, and dilute nitric acid has strong corrosion on carbon steel.
- 2.65*2.25mm 7 meters per kilogram
Post time: 09-01-23Aquaculture galvanized electric welding net this mesh structure is convenient for construction, to ensure quality. Compared with the traditional manual binding, it can ensure the quality of the project, shorten the construction of drug control and shorten the construction period. So now such grids are also being used in new rural construction to enhance wall tension and to prevent earthquakes.
- Fruit green and grass green plastic-coated barbed rope can be said to be the special purpose of the highway, the rest of the use is relatively small.
Use of stainless steel welding mesh:
- Widely used in mining, petroleum, chemical industry, construction, mechanical accessories, protective net, packaging net, barbecue net, barbecue oven net, sintering furnace net, hardware products with net, hardware products with net, arts and crafts with net, vibrating screen net, net basket, food machinery with net, barbecue with net, wall net, grain with net, highway, railway, infrastructure with net.
Post time: 19-10-22Temporary rust prevention is to prepare for the completion of the mission of the protective layer to be removed. The methods include: cajoling corrosion inhibitors, coating antirust oil, peeling molecular compound plastics, drying air, vacuuming, etc. Change the internal structure of the metal: new chromium, nickel and other alloy elements made of stainless steel, but the alloy is not much, expensive, difficult to produce widespread application.
- Four: spray blade thorn rope long service life.
- Galvanized iron wire has excellent endurance and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, commodity packaging and ordinary civilian categories.
- Barbed wire mesh is iron mesh with high anti-corrosion function, the same is also one of the net class of iron mesh is widely used, its efficient anti-corrosion function in aquaculture, construction and other aspects are very popular. Its smooth and regular mesh surface not only increases its own beauty, but also can play a certain decoration effect.
Packaging: Welding mesh is generally packed with moisture-proof paper (color is mostly gray, yellow, plus trademarks, certificates, etc.), some like 0.3-0.6mm domestic sales of small wire diameter welding mesh, because the wire is relatively soft, coupled with small rolls, customers often require baling and bagging treatment, to prevent damage caused by shipment, etc. The wire of the electric welding net is straight, and also with wavy bend (also known as Dutch net). According to the shape of the mesh surface can be divided into: electric welding mesh and electric welding mesh roll.
Post time: 08-10-221: according to the different color of the sprayed blade barbed rope, its price is 2000-2200 yuan higher than the ordinary blade barbed rope, but the cost performance of the sprayed blade barbed rope is much higher.
- Non-proportional extension strength: It is mainly for hard steel without yield point. It is defined as the stress where the residual elongation of the standard distance part reaches 0.2% of the length of the original standard distance.
Hook mesh wire diameter has thickness, fine wire diameter is generally 0.5mm-2.0mm, thick wire diameter can be in 5mm-22mm. Hook mesh is also customized according to different uses, in general, fine silk can be woven into a relatively small hole, thick silk is generally called heavy hook mesh, mainly used in the screening of stones and coal, in short, hook mesh has an important role in many professions.
Regarding the placement of the cage, the top of the cage should not be higher than your standing eye level. This is because tall parrots are usually superior and not easy to tame. But for overly frightened parrots it can be slightly above your eye level. The bottom of the cage is usually equipped with a tray to prevent objects such as bird seed from falling to the ground and to prevent parrots from bumping their feet through the bars at night. The chassis should be covered with newspaper and replaced daily. To help the parrot feel safer, the cage should have a solid side and not be surrounded by bars. If a solid side is hard to find, put one side of the cage against a solid wall.
- Regular maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. With good stability, corrosion resistance, greatly prolong the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved.
- The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.
Post time: 18-05-22Heavy hexagonal mesh is made of steel wire woven into hexagonal mesh by special machinery. This kind of mesh, after cutting and assembling, can be made into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, assembly, etc.
Post time: 18-04-231. It is very important to measure the galvanized iron wire automatically from the cargo reel to the drum, which is very important to the extension characteristics and working life of galvanized iron wire.
The more turns thorn rope, at the same time will shorten some use the length, but its tensile strength is improved and barbed wire manufacturer production products general laps for the 3 ring, very few customers to use the product requires 5 laps, this time both in processing fees and use the length is calculated need extra.
