Aluminum spray paint before solve the production process of many, such as industrial workshop, product standards, interior space parts size workpiece materials (hot galvanized steel sheet, cold rolled steel, hot rolled steel plate, aluminum, glass fiber reinforced plastic anti-corrosion, etc.), product workpiece surface conditions, corrosion, rust, dirt) mass, quality, production regulation, etc. To analyze according to the detailed situation, different manufacturers use different steps, such as the overall steps and quality provisions of passenger vehicle production and manufacturing are basically the same, the former disposal steps generally have the following two kinds:

1. Solution before products

Typical production process: pre-degreasing → degreasing → water cleaning I→ pickling → water washing II→ combination → water cleaning III→ table adjustment → phosphating → water washing IV→ passivation, manufacturers can carry out moderate adjustment according to the specific situation of our factory.

As a product before the solution, pickling rust treatment is indispensable. But in the way of pretreatment, the best aluminum alloy window profile is to separate the rust and non-rust parts, the rust parts to carry out pickling, non-rust parts as far as possible do not carry out pickling.

2. Solve the problem before goods

The solution before the product is to carry out surface treatment of all goods into the tank liquid. At this stage, many manufacturers have chosen the aluminum profile table. There are two kinds of transfer between process flow: manual regulation and intelligent control. More excellent is the use of PLC program flow automatic control system, can complete the process flow between automatic migration. General steps are: degreasing → water cleaning → surface adjustment → phosphating → water washing.

The common machine and equipment to be solved before painting is spraying cooperative cleaning equipment. The basic principle of cleaning is to carry out the whole process of oil removal, phosphating, passivation and cleaning by means of ejecting mechanical equipment force and oxidation.

Typical process flow of spraying cooperative cleaning equipment is: degreasing, water cleaning, surface adjustment, phosphating, passivation, water washing, pure water cleaning.
