Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Pet cats are animals that people keep to relieve loneliness or for entertainment purposes. A pet cat is one of the more perfect animals: good-looking, independent, not dependent on its owner, giving more but taking less. The cat’s sensory organs are extremely well developed and always respond to its surroundings with keen sensitivity. Cats are very docile and have a rich body language to express their emotions. They purr when they are happy and pet you with their front PAWS. Some cats have a special habit of jumping on your lap to impress you. If a cat squats and gently wags its tail from side to side, it is an invitation to play. A twitch of the tail means it is angry.

No matter how good the quality of hot-dip galvanized barbed rope is, it is only attached to the surface of the wire with galvanized layer, and with the cause of chemical reaction, the zinc layer on the surface will gradually lose its effect because of oxidation reaction, which is more prominent in the humid area of the environment. And because, after all, the wire will rust, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
- 3, galvanized wire galvanized process
- The corrosion resistance of hot dip galvanized is much higher than that of cold dip galvanized, also known as electric dip galvanized. Hot wire will not rust for several years, cold galvanized will rust within three months. The cold galvanizing process is used to protect the metal from corrosion, for which the coating of zing filler is used,which is applied to the protected surface by any of the coating methods and dried to form a zinc filler coating with a zinc content (up to 95%) in THE DRY coating.

Open pit coal mine due to poor air quality, a variety of harmful heavy metals are also more, so the corrosion strength of barbed rope products is particularly large, when using galvanized barbed rope must choose hot plating or plastic coated galvanized barbed rope, although the price is slightly higher, but in the long term development is more appropriate. Besides, when the barbed rope is installed near the coal mine, the pile foundation should be fixed to prevent the barbed rope from falling down due to soil erosion, thus losing the protective effect.

Large roll of galvanized wire alloy elements in iron ore, can make copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
-
The type of barbed rope is mainly reflected in the specification of the wire diameter, the thicker the diameter of the barbed rope produced is shorter, at the same time, the price is cheaper, mainly because the production efficiency is relatively high, because the price of the barbed rope is calculated according to the weight when it is sold. On the contrary, the finer the diameter of the wire, the longer the price is higher.

First, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.
- Customers in the order of wire mesh often shop around, most of the customers are compared with the manufacturer given the product price, the company tells you, do not blindly compare the price. To standard, production process, manufacturer strength and other factors lead to different prices.
- All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.

Wet air in rain and snow climate, steel mesh sheet exposed, easy to rust, to avoid affecting the use of steel mesh, it is necessary to carry out simple rust prevention treatment, of course, slight rust float will not affect the use of steel mesh. Common network site storage, rainy days, heavy snow, rainy days and rainy days, how to better save the steel mesh, this is a lot of friends need to consider.
- The chromium-plated layer has good thermal property. When the temperature is heated below 500℃, its luster and hardness are not changed obviously. When the temperature is higher than 500℃, the initial oxidation and discoloration occur, and the hardness decreases when the temperature is higher than 700℃. The friction coefficient of chrome coating is small, especially the dry friction coefficient, which is low among all metals. So the chrome coating has good wear.

At present, there are two processing methods of blade stabbing rope. One is to make it into a spiral shape, and then make a clip treatment. It is not only our common spiral blade stabbing rope, but also a single spiral blade stabbing rope without clip, but even a single helix can not stretch it to a relatively straight. This is mainly because the blade barbed rope is wrapped and wound at the same time, so it can only be spiral.
