extension of a threaded rod how to properly extend a

Due to the implementation of the grassland contract operation obligation system, herdsmen have a high capacity to strengthen and raise their stainless steel barbed rope fence net in grassland pastoral areas, forming the phenomenon of high density and high height of stainless steel barbed rope fence net in grassland pastoral areas, which is destructive and even destructive to the survival of wild animals.
Third, 201 is high manganese content, the surface is very bright with dark bright, high manganese content is easy to rust. 304 contains more chromium, the surface is matte, no rust. Put the two together and you have a comparison. The most important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price will be much cheaper. Because of the low nickel content of 201, the price is lower than 304, so the corrosion resistance is not as good as 304.
Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
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.

The common thorn rope is double strand thorn rope, models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm three, and are galvanized thorn rope (plastic coated thorn rope is rarely used), the thorn distance (that is, the distance between winding wire) is generally 14 cm. Let’s take a look at what these models mean:
They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.
The reason why there are black spots in wire mesh welding is that the action of wire feeding should be timely filled in the melting time, and the development should be appropriate. There is no argon gas, long burning, large current, long distance, blunt tungsten needle and high molten pool temperature are the fundamental reasons for blackening. Continuous burning, is about active welding machine energy selection, machine welding will appear black spots.
Wire mesh welding after galvanized is through the end of the welding and then the cold company to make wire mesh wire mesh steel mesh construction mesh floor heating mesh galvanized or hot galvanized. After the first galvanized welding is to change the wire mesh, after the end of welding can see the welding spot; The two processes are different prices are also very different, the cost of the first plating after welding is low, the appearance is smooth, and the cost of the first welding after plating is higher, not easy to rust.
Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.

2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.
After annealing, the extension rate of galvanized wire is increased, making the product more soft and increasing the scope of application of galvanized wire. After electric galvanized hot galvanized, electroplated copper and other widely used screen production. Building reinforcement binding with galvanized wire mesh braided with the first after plating, plating and other methods, after treatment of galvanized wire mesh or steel wire mesh, has good corrosion resistance, oxidation resistance characteristics, can be used in construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries reinforcement, protection and heat preservation.
The bird cage is the main environment for the birds to live and live in. Only with proper cage and other accessories, can the birds be kept healthy and lively, singing freely and suitable for viewing.

This process has no mold, low processing cost, easy forming, can process a variety of shapes and other characteristics are widely used. But the products of the guardrail are powder impregnated plastic. According to whether it needs heating, it is divided into hot dipping and cold dipping. According to the raw materials of dipping, it can be divided into liquid dipping and powder dipping. Hot-dip galvanizing, as a metal anticorrosion method, is usually to put the steel structure to be derusted into the zinc liquid at about 500℃, so that the zinc layer is attached to the surface of the steel structure.
In our daily life, we are certainly familiar with the construction of power grid. Choosing such special barbed rope can improve the safety factor of the entire power grid during construction.
1, galvanized silk mesh molding sheet must be packed with flat hard materials, to avoid improper packaging and cause eternal deformation. It is important that each package and roll of raw material be marked with product name, standard, quantity, trademark, lot number, manufacturer, date of production, packing symbol, inspector code and inspection certificate.
Due to the implementation of the grassland contract operation obligation system, herdsmen have a high capacity to strengthen and raise their stainless steel barbed rope fence net in grassland pastoral areas, forming the phenomenon of high density and high height of stainless steel barbed rope fence net in grassland pastoral areas, which is destructive and even destructive to the survival of wild animals.
Galvanized wire can be seen as iron wrapped in carbon, when extinguished, the surface is comparable to shallow carbon can contact with oxygen, produce carbon dioxide gas, will wrap it in iron (this is a molten state) radiation in. The more carbon there is in the galvanized wire, the more likely it is to spark. The iron-encased carbon is like dynamite in a dynamite bag, blowing the iron away from time to time.
And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.

The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.
Although galvanized iron wire has the protection of galvanized layer, it does not say that it will not rust at all, but delays the time of rust. In general, cold galvanized iron wire can be kept for 1-2 years without rust, hot galvanized iron wire can be used for 8-10 years without rust. If properly maintained, the use time will be longer. So how to prevent galvanized iron wire rust?
So, do you know how to pick the right dog cage? When choosing a dog cage, focus on quality and practicality! Let’s take a look at it:
5, there are no special requirements: such as whether to shrink packaging, etc.
To many people, a dog cage looks like a prison, but for dogs who have been raised on cage training, it is their home and shelter. A cage should be a comfortable place. Never put a dog in a cage for no reason. They will see it as punishment. (Why do many dogs fail to adapt to their owners’ commands, because whether the paparazzi can come out or not, it is also seen as a punishment.
The main customers of the thorn rope factory are still targeted at farms and plantations, because the demand for thorn rope is often very large.
2. Eliminate caked zinc residue on zinc liquid surface
In use, it can be well used to control the degree of softness and hardness in the annealing process, mainly used for binding silk and binding wire in the construction industry. Its use is not limited to handicrafts, of course, in the construction industry is also widely used. In the early days, the lanterns were made with wire outside and proper candles were placed inside. People hung them in front of the door and it was very beautiful to go up at night.
