One,Features
LQ-A434 Aluminum Alloy Eco-Friendly Anodized Aluminum SheetAgent isStyleSpecifically designed for aluminumSurface cleaning and descaling of alloysPhosphate-free wastewater discharge, beneficial for environmental protection. Particularly suitable for high-silicon aluminum alloys (such as A356, ADC12, etc.).
Section 2: Utilization of Parameters

Pull White: >12 Pt
Warm Degree： 15－25 ℃

Three.Luminance detection method
Lighten up:Pipette 2mL of the bleaching agent solution into a 250mL conical flask using a 2mL pipette. Add 25mL of pure water to rinse the inside wall of the flask, then add 20mL of a 20% sulfuric acid solution. Titrate with a 0.1mol/L potassium permanganate standard solution until the color changes from colorless to pink, and remains for 20 seconds without fading, indicating the endpoint. At this point, read the volume of the 0.1mol/L potassium permanganate standard solution used, which is the concentration of the bleaching point.
FourAdditional Method
Lightening agent should be added if the pull white is less than 12 Pt.BAgentAnd add the white additive A.
The proportion of A agent and B agent for supplementary addition is 5:1.
Five. Slot LiquidMaintain
Solution temperature should be maintained between 15-25°C; excessive heat accelerates medication consumption and causes workpieces to oxidize and turn black, so appropriate cooling measures should be taken.
2. After bleaching, the water wash tank should maintain overflow, with the wash time not exceeding 20 seconds. Excessive acidity or prolonged wash time can affect the bleaching result. Connect the water wash tank to the air tube to enhance the mixing and cleaning effect.
3. After treatment with the degreaser, the parts should not remain in the air for more than 25 seconds; they should be immediately washed with water. The longer they stay, the more prone they are to oxidation and discoloration.
Six.Replacement Cycle
500-liter solutionContinuous production of 45,000-60,000 units(These figures are for reference only; the actual products are determined by the materials used in on-site production.)Please replace the slot fluid.
Section 7: Safety Precautions
This product is an acidic liquid. Avoid contact with skin and eyes as much as possible. Ensure good ventilation when in use, and operators should wear rubber gloves, waterproof boots, safety goggles, and other protective equipment.
