ATA-702 zinc alloy blackening agent at normal temperature
Application descriptionThis product is a decorative black normal temperature treatment agent for zinc alloy. It is suitable for galvanizing and zinc alloy. It can form ash, brown and black on the surface of zinc. It is suitable for the adhesion of the coating layer. It is especially suitable for excellent vibration and antique silver.
main features
The blackening at normal temperature needs no heating, the blackening solution is stable, the blackening time is short, and the energy saving effect is remarkable.
The film is uniform and dense, strong corrosion resistance, firm adhesion, without any buoyancy and pure color.
Equipment materialATA-702 zinc alloy room temperature blackening agent material: should be made of thick wall plastic plate, stainless steel and so on.

Instructions
(1) the oil must be clean, and the surface of the workpiece requires full wetting. Otherwise, the film is easy to flower and poor adhesion. In order to achieve the expected treatment effect, it is recommended to use medium temperature heating and degreasing process. For a workpiece with very little oil pollution, it can be treated with ATA-105 acid deoiling agent directly; for the work piece with heavy oil pollution, first use of other deoiling agents, such as ATA-103Al deoiling powder, ATA-108 normal temperature deoiling agent, ATA-102 neutral degreasing agent, etc.
It is treated with ATA-105 acid deoiling agent.
(2) Wash the scales with ATA-309 aluminum-zinc meter for 1-3 minutes (or soak in 0.5-1% sulfuric acid for 5-10 seconds).
(3) blackening: 1:3 water distribution tank solution, fully stirred after production can be used. After cleaning, the parts without oil scale and rust - free scale are soaked in the treatment liquid, and are moved 2-3 times up and down, then impregnated for 1-3min, and then soaked in tap water. With the development of black production, the effective components of the solution are gradually reduced, and the ATA-702 zinc alloy blackening agent, and ldquo, and and rdquo should be added to the production, and the working fluid can be blackened normally, the concentration is low, the blackening is slow, the film is not dense; the concentration is high, the zinc alloy is easy to corrode and the membrane is loose and easy to take off; blackening and blackening. piece
If the surface has floats, it can be lightly removed; the black film layer is not good enough before the film is dried, and prevent scratches.
(4) The new cylinder opening reaction of this preparation is faster, after a period of use, the reaction speed will be slowed down, and the reaction time should be prolonged appropriately.
(5) With the decrease of the active ingredients in the liquid, the blackness of the extended time can not be reached. The original liquid can be added through clarification and filtration, and the blackness of the cylinder can be increased by 10% each time.
(6) the workpiece after blackening needs to be sealed. ATA-628 dehydration and antirust oil is used to soak and dehydrate. Finally dry.
Matters needing attention
1. the treatment tank is acidic solution, which can be recycled and can be treated with acid discharge standard.
2. if the workpiece is electroplated and brightener, it is recommended to use the company's stripping agent before activation.
3. this medicine is weak acid, so strong acid has great influence on its pH value, and the amount of water washing must be clean so as not to activate acid pollution.
Safety measuresThis agent is acidic, with slight corrosion. It should be operated with acid and alkali resistant gloves and pay attention to labor protection. In the cleaning process should avoid the medicaments sticking to the skin, mouth and eyes, otherwise immediately wash with a large number of clean water, feel unwell should be timely medical treatment.
Storage and transportation methods:Seal and dry the cool and ventilated place; keep the quality for one year. 25 kg / plastic drum packed, transported according to common chemicals.
