NICKEL-FREE SEALER
无镍封闭剂
——
DX-505 Nickel-free room temperature sealer
DX-518 Nickel-free wide temperature color sealer
Product Features
This product is a white mixed powder, which is carefully compounded by precious rare earth, accelerator, stabilizer, penetrant, ash inhibitor, dispersant and surfactant. It is suitable for aluminum alloy anodized film at room temperature and colorless sealing treatment. The product does not contain heavy metal nickel, meets the requirements of environmental protection, completely solves the harm of nickel to workers' bodies, and pollution to the environment and aluminum alloy; in the normal working range, it has fast sealing speed, low consumption and anti-impurity ability. Strong and other advantages, the hardness of the oxide film after sealing, the brightness of the light is improved, and the corrosion resistance is strong.

DX - 505 5-6g/L
Deionized water Margin
Temperature Normal temperature
P H value 3.5-4.8
Time 1-1.5um/min (Reasonable adjustment according to oxide film thickness)
The amount of the blocking agent added is determined according to the result of the assay bath;
— During the production process, the pH value of the bath should be strictly controlled 3.5-4.8, the pH value is too high, and it can be adjusted
with dilute acetic acid; the PH value is low, and it can be adjusted with sodium acetate or dilute ammonia water.
— This product is a weakly acidic agent, avoiding contact with alkali chemicals, hygroscopicity and moisture resistance;
— In some areas, the temperature in winter is low. When using, ensure that the bath temperature is not lower than 20 degrees. Otherwise, the
sealing speed is too slow, which will affect the production efficiency.
This product is packed in 10-20kg woven bag, which is heat-proof and moisture-proof during storage and transportation.
The company has upgrade and improvement rights for all series of products independently developed and produced!

Product Features
This product is a light yellow brown translucent liquid, which is carefully compounded by precious rare earth, complexing agent, buffering agent, stabilizer, penetrant, ash inhibitor, dispersant and surfactant. It is suitable for aluminum and aluminum alloy. The anodic oxidation of the color film and the color oxide film are closed, and the hand feel is smooth; the product is truly wide temperature and uses no nickel and no fluorination; the product does not contain heavy metals such as nickel, cobalt, lead, chromium, cadmium, etc., and meets the requirements of environmental protection. It completely solves the harm of heavy metal nickel to the human body, as well as the pollution of the environment and aluminum alloy; the temperature is selected according to different quality requirements, and the higher the temperature, the better the quality of the closed product.
