1）Dimension of work piece beyond the zinc plating pot

2）Work piece without vent, half closed leakage of liquid zinc hole or

fully closed plating, and no suspension pints.

3）Welding seam of coated parts that is not closed, welding coating

and slag of welding seam does not clean, as well as more serious defect of

coated parts.

5.3 Hang material

5.3.1 Plating rack should be inspected before hang

materials,deformation.cracks.tripping, corrosion and surface adhesion large

area with zinc layer is found and, may not continue to use.

5.3.2 Sort component according to the type.length.materials and surface

condition while hanging.

5.4 Pickling

5.4.1 Hydrochloric acid aqueous solution is used for pickling, hydrochloric

concentration is 40~160 g/l, room temperature as working tempreture.

5.4.2 Compound of pickling liquor

32% industrial concentration hydrochloric acid, 1:1 mixed with water to

produce hydrochloric acid content of 160 g/l concentration of acid pickling

solution. Preparation before adding water and then adding acid, add tube

immersed in the water of hydrochloric acid, and acid fog inhibitor (otherwise

stated) During the pickling liquid in use generally do not add acid until the

reduced content of 40~45 hydrochloride g/l of solution concentration and

solution of ferrous chloride (FeCL2) content of up to 200 g/l, pumping of

waste acid storage tank, and processing.

5.4.3 Acid pickling solution testing once for each class,result posted on the

signs to guide the pickling operation treatment.

6

5.4.4 Pickling time is made according to the plating surface oxide layer and

acid concentration. Pickling operation to speed up the reaction speed,move

from top to bottom plating in acid pickling process must be two to three times,

and then pull above fluid level to check quality of pickling

5.5 Rinsing

Qualified rinse galvanized components must be rinsed in the double

rinsing craft tank through flowing water to erase the surface remaining

pickling liquid and other debris, and then immediately into the plating bath by

flux process.

5.6 Fluxing

5.6.1 Plating agents are ammonium chloride (NH4CL) solution, the working

temperature is 60~80℃, proportion is the solution: 1.03~1.05g/cm3 (room

temperature measurement). Plating agents used in the process should be

supplemented and adjusted in proportion within the limits prescribed.

Assistant pools keep the water level of the low water line and between the

highest water level.

5.6.2 Flux test for twice each batch, its iron content in solution at 10

grams/liter. PH=3~5, quality control. Assistant quality control in the

regeneration cycle, flux heating by heater.

5.6.3 Full immersion plating after rinsing solvent treatment in plating solution,

soak time of 3-5 minutes.

5.6.4 Work piece treat after flux,, chemical treatment and quality inspection is

needed.. Local paint or for any other reason fails to acid clean surface

grinding wheels, wire brushes, scrapers and other tools for processing,

repeat the pickling process operation, rack zinc plating after chemical

qualifying.

5.7 Second-hanging Before Galvanizing

7

5.7.1 If pickling qualified, the work piece which well handled after plating auxiliary should

go on to proceed second-hanging before galvanizing.

5.7.2 Pay attention to the position of hole and characteristics of work piece while

second-hanging and select the applicable hanging point and right direction of zinc flow in

case of any quality problem such as unfavorable air-out, smooth zinc flow and zinc

heaping etc. Second-hanging should reach hot-dip galvanizing requirement.

5.8 Preheating & Drying

After second-hanging procedure, stay in drying tank and make sure the work piece

dry enough and then go on to do hot-dip galvanizing.

5.9 Hot-dip Galvanizing

5.9.1 Zinc Bath

5.9.1.1 Zinc bath is mainly composed of molten zinc. The chemical ingredients of zinc

ingot have to reach GB470 standard. Add proper aluminum alloy in zinc melt which

should net exceed 50g/ton(zinc).

5.9.1.2 Galvanizing work should be started as long as the zinc melt temperature up to

455℃-460℃. Meanwhile, the temperature should stay between 420℃～ 430℃ if

production paused.

5.9.1.3 Fill the zinc everyday while off work to make sure lower the pressure of zinc

melting pot and stay 10-30cm distance between zinc melt and edge of zinc melting pot.

During special producing situation in large use of zinc should fill at anytime.

5.9.1.4 Thickness of the residues in zinc melting pot cannot over 8cm to lower the

possibility of zinc pot corrosion. To do at least twice totally salvaging zinc residue work

each week, the salvager should salve evenly from one side of the pot to another side

and each time should repeat one third of the site where have been salved already. If

miss any work-piece into the zinc pot, salve immediately to avoid corrosion and produce

much more zinc residue.

5.9.2 Hot-dip Galvanizing Work

5.9.2.1 Clean up the zinc melt oxide layer before work-piece into the tank. Put the work

piece slowly into the zinc tank in any case of splashing. Stay 25-35 degree of tilt angle

while the long work piece immersed horizontally.

5.9.2.2 The entrancing time, galvanizing time and outing time is different according to

work piece type, material and standard.

5.9.2.3 Clean up the zinc melt oxide layers and plating auxiliary residues before the work

piece come out the zinc melting pot, and then take out the work piece out of zinc melt

very slowly, let the extra zinc melt flowing into the pot naturally and shake the work piece

by tools to clear away the additional zinc to make sure the appearance quality of work

piece.

5.10 Water Cooling

Work piece after galvanized should be putted into cooling tank to cool down the

temperature, cannot stay long time in zinc pot.

5.11 Passivation

5.11.1 Passivation Solution

Ingredient of Passivation: 0.5% sodium achromatic (potassium achromatic), 0.1%

sulfuric acid solution. Take analysis every week, taking notes and sign board.

5.11.2 According to the technical specifications, Passivation treatment should be start

after cooling down the water if needs necessary passivation.

5.12 Unload and Inspect

5.12.1 Galvanized part should be putted onto the supporting frame by hanging bracket

while unloading, no supporting frame unload method was strictly prohibited.

5.12.2 QC should inspect from exterior after the galvanized part unloaded and repair it

promptly if anywhere has unhallowed flaws.
