- 1. Zinc layer thickness: under normal circumstances, the thicker the zinc layer, the better the corrosion resistance of electrogalvanized wire. This is because the increase in the thickness of the zinc layer can improve the self-corrosion performance of the zinc layer and form a better protective layer.
3, galvanized wire galvanized process
- Zinc coating on steel and ferrous metal plays an anodic role, it is commonly used for those parts subjected to atmospheric or water action, but zinc coating only when the water temperature below 60℃, the anode properties. When the temperature is higher, the potential changes and the zinc to iron becomes the cathode. Therefore, for parts subjected to hot water (such as steam boilers), the zinc skeleton must be approximately 70 microns thick and void free. For parts subjected to low or normal temperature or atmospheric action, zinc coating without pinholes is not necessary.
Post time: 10-04-23- Take the blade cord for example, the quality of the cord and the shape and direction of the surface barbs are what consumers need to consider.
Large roll galvanized wire as a common industrial supplies in daily life, many people will use, but many of them are not standard operation. Cold galvanized wire is one of the many categories of iron wire, widely used, cold galvanized wire is a kind of galvanized iron wire products made of high quality low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes.
The hook mesh is a good material for flood control and flooding. Can also be used for arts and crafts manufacturing, mechanical equipment transport network mountain beautification network – high strength steel wire grid (hook mesh, diamond mesh) hook mesh mountain protection application principle, hook mesh interests, mesh uniform, flat, woven concise, hook woven, beautiful and generous, net, net width, wire diameter is thicker, not easy to corrosion, long life, strong usefulness.
Post time: 14-11-22Spring wire shall have high tensile strength, elastic limit, endurance and fatigue strength, and be resistant to shock and oscillation. The objectives of strength and endurance, especially the prevention of alteration cracks, are key to the consumption of spring steel wires. The inner and outer quality of wire rod directly affect the function of steel wire.
Select cut wire first of all to ensure that the raw material of the silk is exactly the raw material you need, the raw material to ensure that it will be used well. Choose the straightness is relatively high, so that the length of the truncation will be the same, there will not be a lot of length difference, the length of the truncated wire is a very important element to select the truncated wire.
- Barbed rope manufacturers specializing in galvanized barbed rope, hot dip galvanized barbed rope, blade barbed rope, stainless steel barbed rope, plastic coated barbed rope, positive and negative twisted barbed rope production for ten years.
- Choose a cage that can stand up straight in order to keep your dog comfortable. Lay down with your feet out wide. The dog, can save much, can buy a small cage, can also see it as the same as people, give it a bigger cage, so that it can use half to activity, half to sleep. Use an old blanket for your dog’s crate, or buy a pet mat, as long as it’s comfortable.
Hook mesh is hooked flower machine (diamond mesh machine) for all kinds of metal hooks, can be divided into (lock, twist folding locked two. Data
VC wire, stainless steel wire, low carbon steel wire, wire, galvanized wire. Based on entry, rhomboid net, rhomboid net, ring collection, chain net, collection, anchor net, hook breeding, playing net fence. Appearance disposal: according to electric galvanizing, hot dip galvanizing, plastic hook polyethylene plastic bag, dip plastic, spray plastic, hook mesh. According to the use: decorative hook (simple, guardrail, hook mesh, maintenance of another classification: stainless steel data 201,302,304 hook (left, 316, appearance disposal, none).
- The cleaning agent used for cleaning has no effect on the adhesion of the coating and no corrosion on the base material. Acid activation Acid activation solution should be able to remove corrosion products and oxide film from the surface of parts without excessive corrosion of the matrix. Zinc plating may be zinc plated with zincate or chloride and appropriate additives shall be used to obtain a coating that meets the requirements of this standard. After light plating, light treatment is carried out. Passivated parts requiring hydrogen removal shall be passivated after hydrogen removal. Activation with 1% H2SO4 or 1% hydrochloric acid for 5 ~ 15s prior to passivation.
- The uniformity of galvanized wire is reflected in what aspects:
The common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.
It is very important to know the important guarantee of railway transportation, because most of the enterprises now choose the mode of transportation is railway transportation, and railway as an important means of transportation for people to go out, its safety is a social concern. At this time the blade thorn rope can play a very good practical value in various railway trunk lines.
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
- Post-plating treatment of hot-dip galvanized wire for enhanced protection function, decoration and other special purposes (passivation, hot melting, closing and hydrogen removal, etc.). After galvanized, chromate passivation or other conversion treatment is generally required, forming the corresponding type of conversion film is one of the key processes to ensure the quality of plating. Because hot-dip galvanized wire has a long anti-corrosion life, a wide range of applications, hot-dip galvanized wire to net, rope, wire and other ways are widely used in heavy industry, light industry, agriculture, widely used in the manufacture of wire mesh, highway guardrail and construction engineering and other fields.
- Cages are more often used for large dogs, which are very powerful. So choose a dog cage must be strong, otherwise the dog can easily break the cage and escape.
Post time: 09-03-23- If adult dogs touch noses with puppies out of affection, adult dogs touch noses with dogs that have more meaning in life. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
- The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.
The blade gill net has 3-7 buckles every 2 turns, and it is a circle card. After being opened, it forms a spiral shape. When stretching, you must take protective gloves to prevent scratches. When opening, only one side of the gill net needs to be fixed, and then the gill net needs to be opened in the opposite direction. Pay attention to the spacing of the holes should not be too large, otherwise it will affect the aesthetic effect. As long as the time to slowly return to the line, simple operation, convenient construction.
When buying large galvanized wire, first look at the hardness of galvanized wire, only after the hardness reaches the standard can be used. The hardness standard of large coil galvanized wire is a very important performance index and an economical test method. However, for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad.
The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.
Any application environment, users want a better the strength of the welded wire mesh, only need to improve its intensity, will make better the habit of using demand, but to be improved in the strength of this product, also need to have the condition of many sided, just need to see factory in produce what kind of material, the strength of the product also is the material strength, But a manufacturer does not meet the strength requirements in the data, after all, there is no way to make the strength of the product progress, so this is the necessary condition.
Post time: 07-05-22The derusting steel parts are immersed in the melted zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to achieve the purpose of anti-corrosion. The surface of galvanized wire coating can see whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire.
- (3) For some use of special paint spraying should be baked, of course, depending on the size of the area, small can be placed in the oven, large can only be dried first, and then to dry parts for processing, lock baking, if other circumstances can only use high temperature tools bit by bit baking. The products that can be baked in the oven should be leveled at room temperature for 15 to 30 minutes, baked at a low temperature of 60 degrees Celsius for half an hour, and then baked at the reserved baking temperature for one and a half hours, and then cooled down.
Post time: 16-08-22- Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, It is convenient for feeding pets.
That layman how to identify the amount of galvanized, can use the following three methods. Professionals told us that the surface layer of the high-zinc barbed rope would not be particularly smooth due to the zinc behind it, which could be found when comparing the two products. Although the zinc barbed wire zinc layer is thin but relatively smooth.
