- In addition to these reasons, we should pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.

In moist air, a dense basic zinc carbonate film forms on the surface of zinc. Zinc coating belongs to the anodic coating, it is mainly used to prevent the corrosion of steel, its protective performance and the thickness of the coating is very important. The protective and decorative properties of zinc coating can be improved significantly after passivation treatment, dyeing or coating with light protection agent.
Large hexagonal net is called stone cage net, mainly used for mountain protection, hydraulic construction, etc. Small wire hexagonal net is used as a good breeding material, the twisted flower hexagonal net in the welding of the iron frame get on the hexagonal net burning welding coops, pigeonholes, rabbit cages and other cage, hexagonal net is the best breeding material with the net.
No matter how old dogs are, they seem to love to touch noses with people and other animals. In fact, dogs touch noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t nuzzle every human or every animal. They pick and choose who to nuzzle. If they don’t like you, or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell the puppy’s body.
1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.
- There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
Stainless steel wire rope is widely used in engineering cranes. It is generally made of many high strength steel wires. It first consists of a single wire wound together to form a strand, and then some of the strands are wound into a rope core, and then the outer strands composed of other strands are wound around the rope core to form a wire rope.
There is a connection between the hook mesh and the aperture, in short, the general hole small hook mesh, the wire is also very small; Aperture is large, hook mesh wire is generally larger. The weaving of the hook mesh also has certain rules, using the first pre-bent into a wavy wire, and then woven into the hook mesh. According to the knitting method, the hook mesh can be divided into: closed weaving, two-way plain weaving, one-way corrugated weaving, two-way plane weaving, two-way corrugated weaving, rectangular hole weaving.
We can complete the installation of ordinary double-strand barbed rope by using wood shaft or even trees, but the blade barbed rope has high requirements for construction.
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.
Barbed rope is to use iron wire, through winding machine, through a variety of weaving technology, wound in the main line (stranded) made of isolation protection net. There are three ways to twist the barbed rope, as detailed below.
Post time: 10-10-22Stainless steel barbed rope in the way of corrosion is not too, because the surface is not processed but depends on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, will not be similar to hot dip galvanized barbed rope surface corrosion coating problems will rust, because the stainless steel barbed rope internal material and the surface of the material is the same.
Post time: 14-06-22Unless the stainless steel blade barbed rope is specially customized, it is usually produced by the mould with the knife length of 22mm, which is the BTO-22 type we usually call. This is not necessarily the specification from 11mm to 65mm are specifications. Unless the customer insists on customized length requirements, the barbed rope manufacturer will produce BTO-22 stainless steel blade barbed rope.
There are various specifications of barbed rope, which can be divided into two categories: ordinary barbed rope and blade barbed rope.
Poor pretreatment before electroplating; Bath temperature is too low; Poor quality additives or excessive additives and organic impurities can cause poor bonding. The quality of the additive also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the lattice and create stress, causing the coating to blister.
- Large hexagonal net is called stone cage net, mainly used for mountain protection, hydraulic construction, etc. Small wire hexagonal net is used as a good breeding material, the twisted flower hexagonal net in the welding of the iron frame get on the hexagonal net burning welding coops, pigeonholes, rabbit cages and other cage, hexagonal net is the best breeding material with the net.
Post time: 16-06-22Large coils of galvanized wire are divided into hot dip galvanized and cold dip galvanized. Hot dip galvanized wire is dark in color, consumes more zinc metal, forms infiltration layer with the base metal, and has good corrosion resistance. Hot dip galvanized wire can be maintained for decades in outdoor environment. Cold galvanized production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
Cold galvanizing, also called electric galvanizing, is the use of electrolytic equipment to remove oil, pickling, after the pipe fitting into the composition of zinc salt solution, and connected to the negative electrode of the electrolytic equipment. Wire factory on the opposite side of the pipe fittings placed zinc plate, connected to the positive electrode of the electrolytic equipment is connected to the power supply, the use of current from the positive electrode to the negative electrode will deposit a layer of zinc on the pipe fittings, cold plating pipe fittings is first processed after galvanized.
- We have to carefully choose a good cage for the parrot, so that it has a comfortable home.
- Carbon spring steel wire current national and occupational recommendation specifications are divided into two types: one is cold deformation steel wire, also known as cold tension spring steel wire. Cold drawn carbon spring steel wire is first quenched by lead to obtain soxhlet arrangement, and then the surface phosphating, with a large surface reduction rate drawn to the finished scale, the steel wire arrangement is fibrous, has high tensile strength and elastic limit, good winding and change function.
Now hexagonal net is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal net, when the inclined plane gentle, people generally use gabion slope protection system, and in the case of steep slope, people will use gabion mesh gravity protection wall.
