(1) The application method of packaging and binding galvanized shaft wire ordering: ① the pulling position on the goods should be reasonably selected. When used to avoid horizontal movement of goods, the pulling position should be as low as possible; When used to avoid overturning the goods, the pulling position can be appropriately high. ② The use of galvanized iron wire [1] pull reinforcement methods mainly include: figure eight, inverted figure eight, cross, zigzag or reverse zigzag and so on. Various pull methods can be used alone, but also two or more than two kinds of use. The pull should be as symmetrical as possible. (3) When pulling reinforcement, the single or double strands of galvanized iron wire will reciprocate around the goods and vehicles between the two tying nodes, and should be pulled tight galvanized iron wire so that the tightness of each strand is as common as possible, and some of the remaining cross around its own rope rod, and the rest of the tail toward the car.

Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.

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.

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.

2. Eliminate caked zinc residue on zinc liquid surface

Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
