- 3, PVC plastic coated barbed rope protection function is very good
Post time: 01-09-22Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
Second: positive and negative twisting rope cost-effective
- Many luxury cat, dog, parrot, bird and flock cages use square iron tubes. Luxury cage using iron square tube is generally as a cage body frame, and then on each side of the welded iron wire. Square tube cage is characterized by more beautiful shape design, cage body more solid, more surface treatment methods.
- Wire diameter: 6#–20#, this wire mesh is made of low carbon steel wire braided; Aperture: 15′-15′ extra standard can be customized according to customer demand processing. Use: to be used for road beautification belt protection net, maintenance and support seawall, hillside, dam, etc., is to avoid landslides of the best information.
- In general, when exporting and exporting, the blade thorn rope will be packaged and sold, so that the volume occupied in the container is relatively small, which can be easily placed and will not occupy much place.
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, Convenient in pet feeding when more convenient.
- 3, some stainless steel pet cage on the market does not use 304 or higher material, the so-called 202, 201 stainless steel is easy to rust, please users in the purchase of stainless steel pet cage as far as possible not to choose.
Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.

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.
Crevice corrosion is a kind of corrosion in small area, especially in concealed position, which can form vicious corrosion cycle. Almost all the crevice corrosion can occur in a metal alloy, with gas containing active anionic neutral medium Z is easy to cause crevice corrosion, crevice corrosion often occurs in the aperture of 0.025 to 0.1 mm, because of long time gathered, the cracks will exist a series of impurities, coupled with the external environment of damp easily corrode the area of the gap is small.
Galvanized hook mesh standard is thorough, mesh planning: 3cm-20cm, silk planning: 1.2mm-4.5mm, galvanized hook mesh 6000 square meters, some standards are available. Benefits: The selection of low carbon steel wire, surface for cold galvanized (electric galvanized) hot dip galvanized anticorrosion treatment, mesh wire strong, strong protection, long anticorrosion time.
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.
- 1, barbed rope protection net center line along the road within the land boundary 20 to 50 cm set.
- Mainly suitable for flat welding.
Electric galvanized wire shiny white, galvanized wire to exist in a dry and ventilated environment, can not exist in a humid environment. Galvanized wire can not be put together with acid and alkaline substances to prevent chemical reactions and corrosion of galvanized wire. Galvanized wire must also be placed flat to prevent tortuous deformation.
Post time: 10-10-22- Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
Because the size of the plane or the surface of the object in the urban area is relatively small, many stadiums are built in the more prosperous and lively section, with the hexagonal net as a protective barrier, so it greatly reduces the spherical three-dimensional fly out of the field so as to affect the traffic order of bad things.
- Through drawing molding, pickling rust removal, high temperature annealing, hot dip galvanizing. Cooling and other technological process processing. Galvanized iron wire selection of high quality low carbon steel raw materials, after drawing, galvanized and other processes. With galvanized layer, strong corrosion resistance, galvanized layer strong characteristics, electric galvanized iron wire is widely used in construction, highway fence, tie, weaving and other industries.
Friends in the industry know that galvanized iron wire has two kinds of cold galvanized iron wire and hot galvanized iron wire, so what is the difference between cold galvanized iron wire and hot galvanized iron wire? Which is good?
