In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. 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.
- 5, after the light plating should be carried out light treatment.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
1. Simple grid structure, beautiful and practical; 2. Easy to transport, installation is not limited by terrain ups and downs; 3. Especially strong adaptability to mountainous, sloping and multi-curved areas; 4. The price is medium and low, suitable for large area. Main market: railway, highway closed network, field fence, district guardrail, all kinds of isolation network.
Post time: 02-11-22Although 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?
The production process of large rolls of galvanized wire is a level of drawing, through the mold into a slightly smaller diameter than the original. And so on down to the desired length. One pull is not desirable, must be numbered, from coarse to fine is dependent on metal ductility. If it changes too much it just breaks. After drawing to a certain diameter, galvanized, so that the finished product.
There are three main factors affecting corrosion of stainless steel pet cages in Dalian:
Plastic spraying is also we often talk about electrostatic powder spraying, it is the use of electrostatic generator to make plastic powder charged, adsorption on the surface of the iron plate, and then through 180~220 DEG C baking, so that the powder melting adhesion on the metal surface, plastic spraying products are used for indoor use of the box, paint film flat or matte effect. Spray powder mainly acrylic powder, polyester powder, etc.
- The diameter of the wire is generally 0.3mm – 3mm, after the wire is not very strong, need to annealing, annealing this step is very important, can ensure the production of galvanized welding net, with good elasticity and toughness. After welding, the welding mesh becomes black wire welding mesh and can not be put on the market, because its corrosion resistance is poor and the service life is short, so it needs to be galvanized or dipped plastic treatment.
- Galvanized also has several different methods, the so-called hot dip galvanizing is put racing in the zinc bath, need to clean them on metal, which ensures that formed between metal and coating adhesive, after cleaning, the matrix metal is dissolved, to clear any residual oxides of residue and then immerse the substrate metal heating liquid zinc, and metallurgical bonding is formed.
- Three points should be selected before installation, which are the highest point (lowest) and the side line on both sides. The number of thorn rope column is good. When installing, it can be installed gradually according to the hook arrangement of thorn rope column.
Electric welding net is also known as external wall insulation wire mesh, galvanized wire, galvanized electric welding net, wire mesh, row welding net, touch welding net, construction net, external wall insulation net, decorative net, wire mesh, square eye mesh, screen mesh, anti-crack mesh. Stainless steel electric welding mesh, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, welding firm, beautiful, widely used and so on.
Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.
Pet cage You can choose a pet cage that you like or find suitable. It is recommended that you buy a metal cage, with a metal tray at the bottom, of course, the better is stainless steel, plastic can also be, but the plastic tray is very easy to be bitten by pets and damage, plastic tray is also easy to be pet uric acid corrosion, and plastic products are also low, not durable. So pet cages are usually made of metal. This will prevent the pet from entering the house and causing damage, while also providing it with maintenance and not getting sick from running around and touching dirty things.
Post time: 14-09-22There are many categories of large rolls of galvanized wire, and different categories can be applied to different scenarios. The common application of galvanized iron wire is the application of the construction industry. One is the use of binding wire. Whether it is the binding of scaffolding or reinforcement, galvanized iron wire is needed to carry out. There are also 20kg or 50kg bundles of No. 18, No. 16, No. 14, No. 12, No. 10 galvanized coils.
Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After knowing these, we can effectively prevent the corrosion of the dip plastic six side wire mesh, prolong the service life of the product.
2. Eliminate the caked zinc residue at the zinc liquid 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℃.
