Galvanized wire has good toughness and elasticity. With galvanized layer thick, strong corrosion resistance and other characteristics. Products are widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields.
1, galvanized wire is divided into hot dip galvanized wire and cold galvanized wire (electric galvanized wire), the difference is: hot dip galvanized wire is in the heating of molten zinc dip plating, production speed, thick coating but uneven. The color is dark, the consumption of zinc metal, and the matrix metal to form an infiltration layer, corrosion resistance is good, hot galvanized outdoor environment can be maintained for decades.
Cold galvanizing (electric galvanizing) is in the electroplating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 micron, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
2. The drawing wire is made of hot-dip galvanized or electric galvanized iron wire. The surface is smooth and bright, and its tensile strength becomes stronger. It is mainly used for making clothes hanger, drawing, building, communication, web weaving, brush making, high pressure tube, tied wire, handicrafts and so on. High quality and low price, a wide range of wire diameter for you to choose to tie wire to avoid frequent maintenance, tie wire has been increasingly used in daily life, leisure places.
3, galvanized iron wire inspection standard:
(1) First, use the micrometer to measure the diameter of the electric galvanized wire evenly and keep about 0.02mm above and below the contract signing standard, the appearance is neat, no leakage plating, no messy wire.
②, take galvanized wire 20cm acid fog test, through the balance test galvanized iron wire zinc on whether to meet the customer requirements of zinc layer standard, to ensure that the metal wire to achieve the role of rust and corrosion, meet the customer requirements of the service life.
③ The appearance of galvanized iron wire inspection standard requires that the packaging is intact, and the end of the binding wire is inward to prevent scratches to personnel during handling.
