Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.

The invention technology is used to put zinc block into the plating aid pool regularly, 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 filter out the trivalent iron ions in the plating aid; Ferric 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 play the role of plating aid filter.

Many pet cages are designed with a small box in the base, so that pets can clean up when they poop, but also convenient for pets’ health. For example, if there is no excreta box, pet excreta will be on the ground, which is quite unhealthy. If you have a box, it’s easy to take the box out and wash the trash away so it doesn’t get all over the place, so it’s more hygienic.

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.

Fence use: The use of the fence is generally one meter two to two meters a height of the impregnated welding mesh, mesh mostly 6cm, wire diameter from 2mm to 3mm.

Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

The methods to control the thickness of galvanizing are as follows: you can slow down the lifting speed of the workpiece, control the time of galvanizing as far as possible, add the appropriate amount of thinning alloy, reduce the thickness, and improve the temperature of hot-dip galvanizing. But consider the zinc pot, iron pot should not exceed 480 degrees, ceramic pot can be 530 degrees, which can reduce the time of zinc immersion.

The price of galvanized iron wire is relatively low, but the corrosion resistance is excellent, so it is favored by many screen businesses. In the production process of galvanized iron wire, first of all, we should check the equipment to see if there are any problems, and then we should look at the galvanized process, whether there are factors that cause product discoloration. If these problems do not exist, or some of them occur on the same equipment, and some are normal, then we should consider the problem of raw materials at this time.
