The characteristics of large volume galvanized wire is smooth and bright surface, but wet will affect the brightness of galvanized wire, so we must pay attention to avoid humidity when storing, can support a shelf on the ground, so that galvanized wire and the ground isolation, so that it will not be affected by the surface moisture, there is to pay attention to the change of weather, to avoid galvanized wire rain. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.

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.

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.

Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized 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?

Thorn rope factory can not only have one type of product when processing thorn rope, a variety of models can meet the protection needs of different customers.

Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, its characteristics are beautiful, light, folding, easy to store. Pet cage surface treatment is generally: cold galvanizing, hot galvanizing, spraying, dipping, chrome plating, nickel plating and other methods. Pet cage is mainly used for family breeding pets and protection. Tianfu metal products company specializes in the production of various specifications of pet cage such as pigeon cage, dog cage, bird cage, parrot cage and so on.

When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.

Stainless steel blade barbed wire production process is similar to galvanized blade barbed wire production process, usually according to the mold to determine the size of the blade.
