Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
Post time: 08-08-22- Packaging and binding electric galvanized wire is in the state of liquid zinc, after messy physical and chemical effects, not only on the steel plating thicker pure zinc layer, and also generate a zinc – iron alloy layer. This plating method not only has the corrosion resistance characteristics of galvanized wire, but also has a zinc-iron alloy layer. It also has strong corrosion resistance that can not be compared with galvanizing. Therefore, this plating method is especially suitable for all kinds of strong acid, alkali fog and other strong corrosion environment.
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.
2. Eliminate the caked zinc residue at the zinc liquid surface
Did not do the adhesion test of powder spraying or fluorocarbon spray on the packaging galvanized wire, but there are two points for reference: one, in the sealed or air circulation environment, non-metallic volatiles can corrosion zinc coating; Second, zinc above 230 degrees (c) will brittle the base metal. After powder spraying and fluorocarbon spraying, it is necessary to bake at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in decreased adhesion of coating, and even leading to brittle situation of steel wire.
- 2, galvanized welding mesh away from acid and alkali corrosion effect of acid and alkali is electric welding mesh. If the electric welding mesh is accidentally stained with acid and alkali, it should be immediately washed with clean water, and then dried with dry cotton cloth.
- Four: spray blade thorn rope long service life.
The production process of stainless steel blade piercing rope is basically similar to that of galvanized blade piercing rope, and the blade size is usually determined according to the mold.
Cyanogen bath has alkaline zincate bath, ammonium bath, sulfate bath and ammonia chloride bath. Cyanide galvanized solution plating ability is good, the coating lubrication, in production has been selected for a long time, steel mesh chromium plating: chromium plating layer has a high hardness, according to the bath composition and process conditions are different, the hardness can be changed in a large scale 400~1200HV.
Galvanized hexagonal net features: easy to use; Save transportation costs. It can be reduced to small rolls and wrapped in moisture-proof paper packaging, taking up less space. Coating thickness uniformity, stronger corrosion resistance; Simple construction, no need for special technology; It has strong ability to resist natural damage, corrosion resistance and adverse weather effects; Can withstand a large range of deformation, but still does not collapse. Fixed heat preservation and heat insulation effect.
- Positive twist: Twist two or more pieces of wire into a double wire rope and then wrap the wire around the double wire. It’s called a positive twist cord which is a common double strand cord.
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.
The production process of stainless steel blade and galvanized blade is basically similar. The blade size is usually determined according to the mold.
- The installation of guardrail should also follow certain steps, first of all, after the guardrail is transported, according to the length of the guardrail, determine the distance between the column, if the installation of the guardrail field is soft ground, then you can first dig out a 40*40*50cm embedded machine base. If it is a concrete floor, as long as the expansion bolt directly fixed.
Post time: 09-05-22- Hexagonal mesh is also known as twisting mesh, thermal insulation net, soft edge net. It has strong structure, flat surface, good corrosion resistance, oxidation resistance and so on.
Post time: 24-06-22Barbed rope is an isolation protective net made of iron wire, which is wound on the main line (twisted wire) through the winding machine and through various weaving processes. Thorn rope generally has three methods of twisting, the following Haorong for you to introduce in detail.
Benefits of using a pet cage:
There is still some demand for galvanized barbed rope by daily residents, but often the quantity is not particularly much. If the barbed rope factory delivers goods, then the extra freight may be higher than the price of the customer to buy the barbed rope in the market. The thorn rope factory sells to customers who buy in large quantities. There is a lot of demand for it, and it also hopes to find a manufacturer to purchase.
Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.
- 6. If the damage volume of the bird cage is large, it needs to be repaired patiently. If the project is large, it needs to be repaired immediately to prevent the damage from continuing to expand. Of course, you can go to the repair shop to maintain specially.
The external environment has great influence on the preservation of galvanized wire mesh. In the rainy season, it is necessary to pay attention to the air humidity of the workshop, warehouse and other departments. It is recommended to use a humidifier. Usually, the moisture absorption of book paper is larger than that of powder paper, and the pH value is higher. Generally speaking, in the normal environment of storage wire, storage time of two years is not corroded wire phenomenon. However, it should be noted that in the process of handling the iron wire, it should be handled gently to avoid the position of the coiling coil, which will cause the smooth pulling of the wire and affect the production.
- Six: spray blade barbed rope features mechanical strength, adhesion, corrosion resistance, aging resistance, etc., will greatly increase the service life of the barbed rope, anti-UV, anti-aging weathering.
- 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, through lifting, car, shipping to the place, the alloy net connected to each other into a larger whole, construction throwing convenient, fast, good economic performance.
- Determine the size of the dog cage based on the dog’s actual adult size. In general, the cage should be three times the size of the dog’s body and give him enough room to turn around and so on.
- 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.
- Third, after the production process of cold galvanized wire treatment. Galvanized cold galvanized wire needs to go through a series of post-treatment processes to ensure its quality and performance.
- 2, galvanized welding mesh away from acid and alkali corrosion effect of acid and alkali is electric welding mesh. If the electric welding mesh is accidentally stained with acid and alkali, it should be immediately washed with clean water, and then dried with dry cotton cloth.
