English: Galvanizedwire
Produce skill: It chooses high grade mild steel to wire rod is machined and be become, it is to choose high grade mild steel, shape through drawing, pickling divides anneal of rust, high temperature, galvanizing. The skill flow such as refrigeration is machined and become.
Galvanization silk is characteristic: Galvanization iron wire has crackajack tenacity and flexibility, highest on zincic quantity can arrive at 300 grams / smooth rice. Have galvanization layer thick, corrosion resistance is strong wait for character.
Galvanization silk uses: Commodity is used extensively at building, hand skill is tasted, work out silk screen, freeway defends column, commodity is packed reach common and civil wait for each categories.
Galvanization silk divides again for galvanizing silk and cold galvanization silk (electric galvanization silk) difference is:
Galvanizing is to heating plating of the dip inside the zincic fluid of melt, produce rate is rapid, film is deep but inhomogenous, the lowermost ply that bazaar promises 45 micron, highest can amount to 300 micron above. Colour is darker, expend zincic metal much, form with base metal enter a layer, be able to bear or endure corrode sex is good, the galvanizing below the environment outdoor can hold to a few years.
Cold galvanization (electric galvanization) it is to be in eletroplate through electric current one-way sex makes zinc progressively inside groove the metal on plating is outside, produce rate is slow, film is even, ply is thinner, want 3-15 micron only normally, the exterior is shining, corrosion resistance is poor, normally a few months are met rustily.
Relative to galvanizing, electric galvanization produces cost is inferior.
Cold galvanization and galvanizing difference:
Cold galvanization and galvanizing difference are to go up zincic amount is different, can identify from colour they, cold galvanization colour shines hair silvery white contains yellow. Galvanizing shines hoar color. - galvanizing of storage rack uses scale:
Because the film of earning is deeper, galvanizing relatively electric galvanization has defend first-rately function, because this is,make with the iron and steel at strict work environment important safeguard film. Galvanizing goods is in structure of treatment of chemical equipment, oil, marine exploration, metal, electric power is carried, the profession such as shipbuilding has use extensively, pesticide is like in agricultural category sprinkling irrigation, greenhouse and if water is reached,build line of business gas carry, electrical wiring bushing, scaffold, bridge, highway protects the respect such as column, in recent years already abundantly is chosen.
Galvanization silk is common norms is as follows: WiregaugesizeSWG(mm)BWG(mm)metric(mm)

Galvanization silk can divide according to its good:
Build bind using iron wire is to use 22# (0.71mm) , quoted price is low, its characteristic soft toughness is broken well, not easily, it is to build line of business optimal binds one of silk, principal the iron wire that chooses low zinc cold plating to deal with. Principal the iron wire that chooses low zinc cold plating to deal with.
Iron line handicraft, choose a route special treatment, did not decollation, zincic quantity shines equably on beautiful, quote is a bit normally expensive.
Galvanization silk still includes drop a line: Firstly board every heft makes an appointment with 100 kilograms - 1000 kilograms, principal apply to industry, agriculture, stock raising.
The tensile strength of galvanization silk and computational method
Steel wire cross section accumulates the square *0.7854mm2 of = diameter
Newton of steel wire breaking force (N) / cross section accumulates standard of company of silk of galvanization of Mm2= intensity MPa
(One) thematic content and applicable dimensions
This standard is regular the skill demand of the steely galvanization that heat up dip, experimental method and check regulation.
This standard applies to the steel structure that steeliness of carbolic element structure builds, conduit of board member plant, labyrinthian already or the pipe fitting that solders before plating, container and the profiled bar that batch machines the layer of hot dip galvanization with similar goods together applicable with galvanization of steel tube of of all kinds marine, anticorrosion deals with.
(2) adduce standard
GB470 " zincic ingot "
GB534 " chloridize of hydrochloric acid of vitriolic, industry, industry presses industry "
GB/2343 ― 84 " galvanizing is general skill "
93 metals of GB/T13912 ― overburden, steely goods galvanizing layer skill demand
92 low-pressure fluids carry GB/T3019 ― to solder with galvanization steel tube
(3) skill demand
1, galvanizing skill flow chart:
Communication or parcel received is checked - eradicate beforehand - defatted - clean - pickling - clear acid - dip dissolvent - as dry as a chip - hot dip zinc - except Yu Xin - cooling, rarefied - clean - self check rebuilds - goods is checked - qualification leaves factory.
2. Check put in storage
The A, plating that proves eligibility should check personnel by full-time after written visa, ability exemple enters eligible office.
B, qualification is tasted should pile up by all sorts of norms neat.
3. Zinc adheres to quantity and zincic layer ply
A, plating ply is 3 ― when 4 millimeter, zinc adheres to quantity should under 460 grams / rice, namely zincic layer is average ply not under 65 micron.
B, plating when ply is more than 4 millimeter, zinc adheres to quantity should not under 610 grams / rice, namely zincic layer is average ply not under 86 micron.
Uniformity of C, film: Galvanization layer uses corrode of dip of bluestone solution experiment 5 times not to show iron equably at all.
D, film adheres to quality; Plating zincic layer should bear fruit with basic metal connection have contented adherent strength, classics hammer attacks an experiment not to drop, not raised.
4, wait for plating demand
A, wait for plating outside should level off, and the defilement that cannot not eradicate with pickling method. Reach like paint, grease, cement, asphalt ham sodden harmful material.
B, solder all welding line of component part answer sealed, do not get available air.
C, pipe fitting and look parts of an apparatus must have exhaust and the aperture that enter zinc.
The product that D, workpiece should not bring whorl solders steel tube, if have,whorl should try to safeguard.
5, experimental method
A, zinc is adherent the quantity determines choose magnetic ply plan, ply of layer of direct measure zinc.
Uniformity of B, film determines choose way of experiment of corrode of bluestone solution dip.
6, extend dismiss idea
A, adherent to zincic layer quantity, zincic layer ply, the uniformity of zincic layer, when adherent sex is open to question, take sample and commodity to make a test in the galvanization below condition of same mastery of a skill or technique, do not agree with this normative demand for reject.
B, commodity leaves factory method of examination at random, if first time is unqualified, press concerned regulation examination at random again, if still unqualified, decide this batches of commodity are unqualified.
7, the exterior
Appearance of A, film is successional and have practical lubricant.
B, plating device connection disapprobation has stream hang, drop stay or slaggy existence.
C, plating appearance should not have leakage plating, show the weakness such as iron, but defect exists to agree when following state. A. Leakage plating area is a diameter 0.5 millimeter mottled below. B. Without giving thought to plating large and small, leakage plating area is in of diametical 0.5-1 millimeter mottled, in every square centimeter Neibuduo at 3 o'clock, and in plating total mottled number is not surmounted at 10 o'clock. C. Horny part is received in blame connection or blame, do not surmount 1.5 millimeter highly stream hang drop stay or slaggy. D. Plating the feeling bruise with hanger and operation thing, but do not show iron.
8. Material
Ingot of A, zinc: Should not a zinc under GB470 regulation.
B, vitriolic: The one level that should agree with GB534 regulation is strong vitriolic.
C, hydrochloric acid: Should agree with the one class thick hydrochloric acid of GB534 regulation.
D, change by: The one class chloridize that should agree with GB2946 regulation is pressed. - storage rack
