Galvanized wire has good toughness and elasticity. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, weaving screen, highway guardrail, product packaging and daily civil and other fields.
1, galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) distinction is: hot galvanized is immersed in molten molten zinc plating, production speed is fast, the coating is thick but uneven. Dark color, zinc consumption metal, and the matrix metal formation of infiltration layer, good corrosion resistance, outdoor environment hot dip galvanizing 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, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 micron, the appearance of bright, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, electric galvanizing has lower production cost.
2. Wire drawing 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 hangers, making, building, communication, netting, brush making, high pressure pipe, thread binding, handicrafts and other aspects. High quality and low price, a wide range of silk diameter for you to choose to tie the wire in order to avoid frequent maintenance, tying the wire has been increasingly used in daily life, leisure places.
3, galvanized iron wire inspection standards:
(1), first use micrometer to measure the diameter of galvanized wire uniform and keep in the contract signing standard about 0.02mm, neat appearance, no leakage plating, no messy wire.
(2) Take 20cm of galvanized wire for acid mist test, and check whether the amount of zinc on galvanized wire meets the standard of zinc layer required by customers through the balance to ensure that the metal wire can achieve the role of rust and corrosion prevention and meet the service life required by customers.
(3) The appearance of the inspection standard of galvanized iron wire requires that the package be in good condition, and the end of the binding wire is inward to prevent scratches to the personnel in the process of handling.
