Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
Hot wire is made of high quality low carbon steel, high carbon steel, after drawing, hot galvanized processing galvanized wire. Hot dip galvanized wire production process: wire rod – drawing – annealing – drawing – annealing – galvanized. Hot dip galvanized wire has the characteristics of thick coating, strong corrosion resistance and solid coating. And according to the special needs of users, according to the industry standard to provide various specifications of galvanized wire. Hot-dip galvanized wire is of better quality than electrodip galvanized wire. In the production process, hot dip galvanized wire has more than one annealing process, so the corrosion resistance of hot dip galvanized wire is stronger than that of electric galvanized wire.
Galvanized barbed wire (barbed wire) is made of galvanized barbed wire twisted on the main wire, so as to play a protective and isolation role. Among them twist weave way is divided into single twist weave and double twist weave. Construction methods include direct installation and spiral insertion.
2, oil: it is recommended to use cloth (there is a kind of textile cloth for polishing glasses, do not knit, because the nap is easy to fall off), oil to the inside and outside of the cage. The amount of oil is not much, because the bamboo material is old, density and hardness are relatively high.So, do you know how to choose the right dog cage? Choose a dog cage to focus on quality and practicality! Here’s a look:
The service life of the original galvanized iron welding mesh is very limited. Generally, good iron railings can only be used for about 2 years, and then renovated until the service life, which is not only time-consuming but also has safety risks. After the appearance of zinc-steel railings, the service life has been increased to a great extent in the post-processing. Generally, it can be used for at least 20 years. To improve the service life of zinc steel railings, we first have a brief understanding of the product characteristics of railings. Then from the maintenance aspect, it is necessary to maintain. Maintenance method of electric welding mesh:
The prepared black wire welding net is placed in environmental protection galvanized equipment for galvanized treatment. The surface of galvanized welding net is evenly covered with a layer of metal zinc. The corrosion resistance of zinc is very good and it is not easy to be oxidized. The wire diameter error of galvanized welding mesh is very strict, and the gap should be controlled at about 0.02 mm. But whether the tension of an electric welding mesh is qualified, can only be tested by professional tools.
For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by customers. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this thing is more important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized silk, the weight can reach 300kg/ roll or 800kg/ roll.
Barbed wire is used to make barbed wire, in part, to prevent livestock theft, because the surface is covered with sharp spikes that make it very difficult to penetrate through the barbed wire. On the other hand, it is because livestock generally have the habit of charging, and the barbed rope is used to circle, which makes livestock dare not rush to charge the barbed rope, thus saving the user’s use cost.
Barbed wire even in the mining industry also has a higher embodiment, because the selection of low-carbon materials to make it has a general iron mesh does not have the flexibility, determined its plasticity in the use, and then can be used in hardware crafts in the deep processing production, as the wall plastering, inside leak prevention crack and so on. Its light net body, the lower cost, can let the customer realize its economic benefits.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
Remind you to buy galvanized iron wire, should be stored in dry, good ventilation conditions, do not contain corrosive gases, do not mix with the production of organic volatile gas paint, plastic and other substances in a good environment. If conditions, for galvanized parts to increase reliable inner packaging, and put desiccant. If the zinc layer white spots and hair, only mechanical removal, and then normal passivation, or thoroughly washed off the zinc layer after re-plating.
3, hexagonal network customized weight, the greater the weight, the more sufficient the material.
The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.
