Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
- The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.

- Determine the size of the cage based on the actual size of the dog as an adult. In general, the cage should be three times the size of the dog’s body, with enough room for the dog to turn around and so on.
- Great attention should be paid to pickling of large rolls of galvanized wire. Acid is highly corrosive. Therefore, when adding acid, the acid must be poured into the water, and it is along the wall of the cylinder, and not thrown down at once, so as not to cause splashing. Remember the order of acid pouring, acid into water rather than water into acid, water into acid will cause splashing and boiling, when pouring acid must wear protective glasses, beside must ensure that there are no non-professional people watching, so as not to cause some acid splashing danger.
- The patented technology is used to regularly put zinc blocks into the plating aid pool, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter to filter out the trivalent iron ions in the plating aid; The trivalent iron ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to give full play to the function of plating aid filter.
