  • (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.

  • For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by customers. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this thing is more important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized silk, the weight can reach 300kg/ roll or 800kg/ roll.

  • In the rolling process, if the surface of the steel wire is rough, the relative friction coefficient of the steel wire and roll increases, the friction resistance increases, the steel wire elongation decreases, the width increases. In the production of weighted leather material is easy to wide, is because of its rough surface. On the contrary, the surface of the steel wire is smooth, because the friction resistance between the steel wire and the roll is small, it is easy to extend, and the width is small. Domestic steel wire in order to prevent rust, the surface coated with butter, such as butter removal is not clean, easy to slip when rolled flat, also affect its width.
