AL-ESD (A/B)

characteristics

Aluminum acid sand sand remover AL-ESD (A/B) is a two-component acidic liquid sand remover. Less pollution and long life. The sand blasting effect is good and easy to operate. Sand surfaces with different particle sizes can be made by mixing A and B liquids in an appropriate ratio.

conditions of use

• AL-ESD (A): The company provides two raw materials: additive No. 1 and additive No. 2. After mixing 18 kilograms of phosphoric acid and 12 kilograms of sulfuric acid, add 1 liter of additive No. 1, stir well, add 250 ml of additive No. 2, and stir well to obtain 32 kilograms of AL-ESD (A) finished product. The concentration of phosphoric acid is required to be 80% or more, the specific gravity is about 1.65, and the Baume degree is 57°Bé or above. The sulfuric acid concentration is required to be 90% or more, the specific gravity is 1.8 or more, and the Baume degree is 57°Bé or more.
• AL-ESD (B): Add 16 kilograms of phosphoric acid to 16 kilograms of No. 3 additive, mix and stir evenly to obtain 32 kilograms of AL-ESD (B) finished product.
• Add the two solutions A and B in appropriate proportions according to product requirements.

For example, when opening the cylinder, A:B = 6:1, then the ratio when adding supplements is A:B = 3:1.

• Tank material: FRP, stainless steel SUS316, lead tank.
• Due to the high operating temperature, water will continue to evaporate and should be replenished in time (about 5-10% of the solution) to maintain the specific gravity of the working fluid between 1.7-1.72.
• The role of aluminum acid sand remover AL-ESD (A/B):
• AL-ESD-A: Adjust the gloss and improve the uniformity of the sand surface.
• AL-ESD-B: Improve the sand surface effect and enhance the sand production ability of the solution.

Process flow:

Degreasing (AL-CLEAN DA5 or DAC-8)→ Water washing → Sand treatment (AL-ESD)→ Water washing → Stain removal (stain remover AL-D40)→ Water washing → Anodized (sulfuric acid)→ Water washing → Dyeing → Water washing → Hole sealing ( PLS or PHS-5000)→ Water washing → Hot pure water → Drying

package and storage

The packaging specification of No. 1 additive is 4 liters/barrel, the packaging specification of No. 2 additive is 1 liter/bottle, and the packaging specification of No. 3 additive is 32 kilograms/barrel. Store in a cool and dry warehouse. Direct sunlight is strictly prohibited. High temperatures and high temperatures must be covered and sealed after use.

precautions

• AL-ESD (A/B) is an acidic substance and should not be touched with your hands. Wear rubber gloves when using it.
• A suitable amount of aluminum ions (about 1 g/liter) should be added to the newly opened bath solution to avoid jagged patterns on the surface of the workpiece.
• Too much water will lead to uneven surface effects after treatment, so too much water should be brought in after washing as much as possible.
• Additives in the stock solution may precipitate. Please shake well before using.
• The workpiece should be constantly shaken during immersion treatment, and the time after treatment should not exceed 20 seconds.
• Before AL-ESD (A/B) treatment, the workpiece must be thoroughly degreased and destitute, otherwise spots may occur.
• After AL-ESD (A/B) treatment, the stain and film must be removed before anodic oxidation can be carried out.
• Tank liquid must be discharged only after passing wastewater treatment.
