  • Hot dip galvanizing, also known as hot dip zinc and hot dip galvanizing, is an effective way of metal corrosion prevention, 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 member is attached with zinc layer, so as to play the purpose of anticorrosion.

  • Galvanized wire coating has galvanized, aluminum, nylon or plastic coating. Zinc plating is divided into thin coating after steel wire plating and thick coating after steel wire drawing. The mechanical properties of thick coating are lower than that of smooth steel wire rope, and it is suitable for use in serious corrosive environment. Aluminized wire rope it is more resistant to corrosion, wear resistance, heat resistance than galvanized wire rope, using the method of production after the first plating. The wire rope coated with nylon or plastic is divided into two kinds: coated rope and coated rope.

  • Since nose touching is an important part of dogs’ social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses often when they are young, they will grow up to have softer personalities and be far less likely to hurt people.

  • 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.

  • Hexagonal guardrail net custom corrosion lost the original characteristics, in the shape, color and mechanical properties will change, resulting in equipment damage, pipeline leakage, etc., specifically, is prone to fracture, lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the customized corrosion of hexagonal guardrail net and extend the service life of the product.

Blade barbed rope is very good in the market reputation, and different types of blade barbed rope can play different roles, so how should we choose blade barbed rope? What are the main points?

  • Speaking of pets, we have to talk about parrots. Because it’s easy to take care of, and it can talk, talk to you, and make you laugh. Parrots love to climb, so there is a cage with bars that are made up of horizontal bars rather than vertical bars, because this makes climbing easier for the parrots.

  • Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation

  • 3. 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.

  • The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

  • Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.

  • 2. When there are natural barriers such as canals, ponds and lakes on the side of the road, barbed rope protection nets shall not be set up in the section where there is no need to worry about people and livestock entering and illegally occupying the road land.
  • If adult dogs and puppies touch noses out of love for the dog, then adult dog nose touch is more meaningful. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
  • Hard black galvanized iron wire is made of low carbon steel wire by wire drawing machine. Hard black galvanized iron wire is the first feature of high hardness, bright appearance. It is mainly used for welding clothes hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawing. Soft black galvanized iron wire is the first feature of good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving technology, welding net, process products of welding.

  • Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.

  • There is good toughness and elasticity, simply put, can be easily made into various shapes, and zinc as a coating is silver, very beautiful. Such characteristics make hot dip galvanized wire handicrafts, woven screen and other aspects have also been applied. Hot plating wire selection of high quality low carbon steel rod processing, is the selection of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes.

  • The different spacing of the thorn rope is mainly in order to save costs to consider, because if they are too close, then obviously a little waste of resources, but the installation is too sparse will not work. Usually the bottom spacing is about 10cm, and the top is up to 20cm, this is because the higher the place is more difficult to climb over, usually more than one meter without the help of tools it is difficult for ordinary people to climb over, and the bottom because of the relatively tight can prevent personnel from drilling in the past.

  • From the plastic spraying, spraying blade gill net (pvc blade gill net, plastic blade gill net), also known as spraying blade barbed wire, spraying blade barbed wire is produced in the future, to rust treatment by the attack. Spray appearance treatment makes it have quite good anticorrosion ability, beautiful appearance, good waterproof effect, easy construction, economic and practical excellent characteristics. Spray blade thorn rope is a plastic powder spray on the product blade thorn rope of an appearance treatment method.

  • The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

  • Hexagonal barbed wire is divided into small hexagonal net and heavy hexagonal net. Heavy hexagonal net is also known as large hexagonal net, large size hexagonal net, mountain protective net, hanging net, stone mesh, gabion net.

  • Wire mesh first welding after galvanized is through the end of welding and then the company to produce wire mesh wire mesh steel mesh construction mesh, floor heating mesh galvanized or hot dip galvanized. First galvanized after welding is to change wire mesh, after the end of welding can see the solder joint; The two processes are different in price. The cost of plating after welding is low, the appearance is smooth, and the cost of plating after welding is high, and it is not easy to rust.

  • During this process, each time the wire is pulled over, the surface hardens due to the high friction temperature. So basically every time you pull it you have to annealing it in the furnace. On the one hand, it is to reduce the surface hardness. On the other hand, during the process of wire pulling, only the surface is deformed, and the center is unchanged. So there’s a lot of stress inside. Therefore, it is necessary to rely on annealing to eliminate the internal stress, so that the wire becomes soft again to eliminate the stress before being drawn again.

  • The precautions of galvanizing wire in galvanizing are introduced in detail! When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.
