  Tank & Processing Parameters

  Tank Chrome free ash removal agent: 5-20g/L   
 Nitric acid (68-75%): 100-150g/L
 Processing
 Chrome-free ash removal agent: 5-20 g / L 
 Nitric acid (68-75%): 1: 100-150 g / L 
 Temperature: normal 
 Time: 30-90s

Maintenance:
1. In the process of production, chromium free ash remover is added according to the production quantity.In general, one ton of aluminum profile is consumed chromium-free ash remover: 4-6 kg.
2. Avoid bringing too much dirty debris and contaminate the tank liquid during operation. It is recommended that the bottom of the tank be cleaned every six months.

  Advantage

1. No chrome formula, more environmental protection.
2. The traditional method of removing ash by sulfuric acid or nitric acid, it's difficult to remove the copper, zinc and other metal ions suspended ash,this product has a good effect of removing ash and make it gloss.
3.Compare with sulfuric acid and nitric acid solutions,it has a longer life and less dosage.Non - corrosive to aluminum and alloy materials, short immersion time.
4. Wide range of process parameters, low cost and simple operation.

  Package

Seal packaging in plastic barrel ,25 kg /barrel.
