a. Turn off the sewing machine and unplug it from the power source.
The machine is simple enough, and you’re buying it for the strength and durability, not the bells and whistles. But it will auto-wind your bobbin (the lower spool of thread beneath the needle) and includes a hundred or so stitching patterns, if that’s your thing. There’s a dial selector for the type of stitch, and then a dial to adjust the length of it. You can tackle button holes, add zippers, tailor pants and shirts, and all of that.

1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.
- Product features: hot dip galvanized electric welding mesh surface flat, uniform mesh, straight warp and weft wire, diagonal accuracy within 3-5 mm. The structure of the net surface is strong, strong integrity, with strong corrosion resistance, beautiful, wide use and other characteristics.
- Galvanized wire can be seen as iron wrapped in carbon, when extinguished, the surface is comparable to shallow carbon can contact with oxygen, produce carbon dioxide gas, will wrap it in iron (this is a molten state) radiation in. The more carbon there is in the galvanized wire, the more likely it is to spark. The iron-encased carbon is like dynamite in a dynamite bag, blowing the iron away from time to time.
- Under normal circumstances, the organic matter contained in galvanized wire can make electroplating speed significantly reduced. 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.
Post time: 15-12-22The vertical distance between the lower edge of the Nestor roller cage and the upper edge of the reinforced concrete protective fence is 0.05m. Longitudinal reinforcement adopts hot-dip galvanized netting, double-twist weaving process, barbed wire 2.2mm, main line 2.5mm, netting joint card adopts galvanized steel plate stamping or Q235 carbon steel plate stamping for galvanized.
The whole welding process of galvanized steel wire mesh does not need special technological methods, good weldability. However, in a few cases, the welding process will present difficulties: the converter steel produced by the old smelting method has high nitrogen content and high impurity content, resulting in high cold brittleness, added aging sensitivity, lower quality of welded joints, and poor weldability.
Then are there other barbed rope products with the same ability to prevent corrosion at a lower price? The answer is yes, the latest zinc-aluminum alloy barbed rope developed by our factory is a relatively new type of barbed rope products, which has anti-corrosion anti-aging ability can effectively prevent rust aging of barbed rope, at the same time the price is lower than stainless steel barbed rope, only half of it.

Large rolls of galvanized wire in oxygen violently extinguished, spark, and sodium block, magnesium strip in oxygen extinguished, no spark phenomenon. This phenomenon is determined by the composition of galvanized wire. The galvanized wire used in the experiment is pig iron or steel wire, pig iron and steel are iron and carbon alloy, containing iron and carbon two elements of complex material. Carbon in galvanized wire will produce carbon dioxide when extinguished, solid into gas, volume will shrink rapidly.
- The higher the carbon content of steel wire, the worse its plasticity, the smaller the section compression and elongation of steel wire, steel wire in rolling deformation is difficult, the width of the smaller. For alloy steel wire, because the alloy element dissolved in solid solution can improve the cold working hardening rate of steel wire, its deformation resistance is large, the rolling width is small, and it is easy to crack.
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℃.
Post time: 29-04-22The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh is attributed to a hook mesh, it is the selection of galvanized wire, hot dip galvanized wire as raw materials, woven through the hook mesh crimping truncated.
- With a large pickpocket used for steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for galvanized steel wire; Zinc pot steel wire outlet in 30 minutes, with pickpockets back and forth, until the large, floating zinc residue into brown, real zinc ash, zinc ash surface. The extracted zinc ash should be brown yellow real zinc ash, zinc surface, effectively reduce zinc consumption.
- Stainless steel wire drawing is a metal working (stainless steel) process, is a popular surface treatment technology in the stainless steel and aluminum products industry today. It is the effect of drawing stainless steel and aluminum products. So galvanized wire and stainless steel wire are two different products. Defects such as surface film and surface inclusion can be found and treated by conventional techniques in order to locally remove the surface film and surface inclusion from the surface of galvanized iron wire. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.
- 1, prepare disinfection dog cage utensils: small brushes, old toothbrushes, latex gloves (can effectively prevent corrosive pure disinfectant damage to the skin), birdish, and household commonly used disinfectant.
Heavy hexagonal net, also known as large size hexagonal net, or gabion mesh, made of steel wire by twisting mesh machine. This product is very versatile.

Post time: 28-04-23- Regular maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. With good stability, corrosion resistance, greatly prolong the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved.
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.
River isolation network because of different regions are not close to the same, some places called river guardrail network, reservoir isolation network and called river bridge guardrail and so on, but they refer to the same kind of product, we all know that the river isolation network fence itself is a kind of obstacle, to prevent people and cars falling into the river, if installed river isolation network will not appear such a problem, Its setting is conditional, generally in the river fence set guardrail and more people and vehicles installed guardrail maintenance, the relative risk of discrimination. As long as the correct planning, guardrail to play its own function and advantages. Today, I will introduce to you the style of the river isolation network.
Annealed wire is a soft iron wire made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. The composition of iron wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet rolled into 6.5mm thick steel bar is the wire rod, and then put it into the wire drawing device into a different diameter of the line, and gradually reduce the aperture of the wire tray, cooling, annealing, plating and other processing technology made of various specifications of iron wire.
- 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.
The application of black iron wire in the process is mainly through the hot metal billet rolled into 6.5 mm wire rod, and then put it into the wire drawing device into a different diameter line, and then gradually reduce the aperture of the wire drawing disk, cooling and annealing, coating and other processes, made into a variety of different specifications of iron wire, this kind of iron wire and ordinary black iron wire compared, will be softer, Softness is also very uniform, color is consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding hanger, reprocessing industry.
For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering nets, the mesh should be less than 20 and the diameter should be greater than 1 mm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering nets. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.
