Wide-temperature color nickel-free sealer LX-C6629 is a light yellow semi-transparent liquid, made of metal salts, complexing agents, buffering agents, stabilizers, penetrating agents, ash suppression agents, dispersants, surfactants and other carefully blended, suitable for aluminum and aluminum alloy anodic oxidation film and the color oxide film sealing treatment, smooth feel; truly achieve the use of wide-temperature nickel-free non-fluoride; Wide-temperature color nickel-free sealer LX-C6629 Does not contain heavy metals nickel, cobalt, lead, chromium, cadmium, to meet the requirements of environmental protection, a complete solution to the hazards of nickel on the human body of the workers, as well as the environment and the pollution of aluminum alloy; according to different quality requirements to choose the use of the temperature, the higher the temperature the better the quality of the closure of the advantages. Reduce the waste of replacing the tank due to different requirements; within the normal working range, it has the advantages of fast closing speed, low consumption, strong resistance to impurities, etc. The hardness of the oxide film of the closed profiles, the brightness increases, and the corrosion resistance is strong;

1, process parameters (recommended range)

Nickel-free sealant LX-C6629: 4-6g/L

Deionized water: the remaining amount

Temperature: 25-95℃

PH value: 4.8-5.8

Time: 1.0-1.5μm/min (reasonably adjusted according to the thickness of oxide film)

2、Tank liquid maintenance

(1) Determine the amount of sealant added according to the results of the laboratory tank liquid;

(2) Strictly control the PH value of the bath liquid 4.5-5.5 during the production process. If the PH value is high, dilute acetic acid can be used to adjust it; if the PH value is low, sodium acetate or dilute ammonia can be used to adjust it.

3, Precautions

(1) Wide temperature color nickel-free sealer LX-C6629 is a weak acidic agent, avoid contact with alkali drugs, hygroscopicity, moisture;

(2) Individual regions with low winter temperatures, the use of the tank liquid temperature should not be less than 20 degrees, otherwise the closure speed is too slow, affecting the production efficiency.

4, packaging and storage and transportation

This product is packed in 25kg plastic drums, and it is protected against heat and moisture during storage and transportation.

Wide-temperature color nickel-free sealer LX-C6629 has a good fixing effect on the pigment color of aluminum anodic oxidation film, which can effectively close the pores of aluminum and aluminum alloy anodic oxidation color film, improve the hardness of the oxidation film, brightness and corrosion resistance, and make the surface of the treated material feel smooth, no frost, no water marks and good abrasion resistance. The regulation of concentration, temperature, time and PH in the process of use has a greater impact on the sealing effect.
