  • Before wall plastering, the wall column is connected to the gap construction wire mesh, which can play a certain strengthening and heat preservation effect. The mesh is hung on the interface surface of different grassroots, and the length of each side should meet the requirements of 100mm, so as to prevent shrinkage and cracking caused by different grassroots. Mesh wire diameter can also determine the effect and efficiency of construction, mesh fine laid up convenient soft, high construction efficiency; Of national standard can assure quality, but laid respect is inferior to fine construction fast.

  • Birdcage is the main environment for watching birds to carry out activities and roosts, “work to do a good job, must first improve its tools”, the applicability of bird equipment, is one of the keys to raising birds well. Therefore, only equipped with appropriate cage and other accessories, birds can be healthy and lively, singing freely, suitable for viewing.
  • (2) can be used as breeding net, sheep net, cattle net, chicken and duck, isolation chicken and duck house, play the role of poultry protection;
  • Different from double strands of barbed wire to install directly on the ground, the blade thorn rope is fixed on some affiliate products just again, as was the case according to the common on the wall, often wall width is far lower than the diameter of the blade thorn rope under the premise of no such device is fixed in place, use special stents to prevent blade thorn rope can better protect us.

  • Choose birds, raise birds before you need to choose the right birds, generally choose young birds, or minor birds, the requirements of health, strong activity, these birds are relatively easy to keep.

  • 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.

  • Compared with the traditional braided and twisted barbed rope, the price of raw materials is relatively high because of the relatively complex technology.

  • Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It is made of single – layer mesh. Its mesh, mesh wire, galvanized and PVC film properties and the same as the cage. This product can be different shapes and sizes of the block stone into the alloy net to form a flexible whole, can be lifted, car, shipping to the designated place, the alloy net connected to each other into a larger whole, construction throwing convenient, fast, good economic performance.

  • 1. The surface of the stainless steel pet cage is deposited with dust or alien metal particles containing other metal elements. In the humid air, the condensed water between the attachment and stainless steel will connect the two into a micro cell, which causes the electrochemical reaction and the protective film is destroyed, which is called electrochemical corrosion. To avoid this situation, as long as the stainless steel surface is clean, you can ensure that the stainless steel pet cage does not rust.

  • The large hexagonal mesh is called the stone cage net. Stone cage net before delivery, must be folded into a simple surface, packed compressed after delivery. Then put it in the right position to open, and then the block diameter suitable stone into the cage, the cover is tight, and then the various stone cage net and the adjacent stone cage net tied up.

  • Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.

  • The 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.

  • Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering by immersing a steel member in a molten zinc solution. With the rapid development of high-voltage transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electric galvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, even up to 200μm. Hot dip galvanizing has good covering ability, dense coating and no organic inclusions.

  • ⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles.
  • 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.

  • However, because the bath contains highly toxic cyanide, the gas escaping from the electroplating process will do great harm to the health of workers, and its waste water must be strictly treated before discharge. Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be used in some outdoor guardrails or fences, especially on handicrafts, which are also of great use. Galvanized iron wire is not easy to rust and oxidation on the surface.

  • The cooling circulation system uses spray to cool the drawing die, and takes away a lot of heat generated by the drawing machine in high speed drawing in time to ensure the quality of the wire. Control drawing process parameters: drawing speed 10 ~ 12m/s; Winding tension 8 ~ 10N; Measuring length 30km; The mass fraction of lubricant is 3.5 ~ 4.5%; pH value of lubricant 7 ~ 8; Lubricant temperature 30 ~ 40℃.
