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.

The protective duration of galvanized iron wire is closely related to the thickness of galvanized iron wire. In general, zinc layer thickness needs to be very high in dry main gas and indoor applications, but in harsh environments. Therefore, in the selection of galvanized layer thickness, the impact of the environment should be considered. If galvanized iron wire products of different diameters are required, material selection and coating should be controlled reasonably.

Even so, when they come out, they make trouble, even though they know they will be punished, but they are only in a cage.) If you have time to refer to some foreign dog books, also strongly advocate cage training as a puppy. Before starting cage training, the cage is padded with a water bottle, some fun toys and bones to chew on. The cage door must be opened. Order the dog into the cage, then lure it into its new den with tasty cookies.

Galvanizing is a process of coating a metal surface with zinc in an electrochemical reaction on the metal surface to improve the corrosion resistance of the metal. Wire drawing is a process in which metal materials are drawn by mechanical methods to reduce their cross-sectional area and increase their length. So, the combination of galvanized to wire drawing two processes, what impact on the performance of the product?

The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

Dip plastic six side barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, in particular, is prone to fracture, lose the original protective function.

If the surface of galvanized wire is black and the galvanized layer is thin and uneven, the galvanized wire is partly because the inventory storage time is longer, but also because the production technical requirements of galvanized wire do not meet the standard and lead to the quality problems of galvanized wire. According to the use of galvanized wire is different, galvanized wire has soft and hard, then the galvanized wire used for binding requires the flexibility of galvanized wire is better, the flexibility of galvanized wire is good, and it can be easy for workers to operate.

In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.

Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

Cattle net in the outdoor use of a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know that cattle net if long exposure to harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?

Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
