Production technology Transfer of Environmental protection new aluminum alloy three-in-one low temperature polish

Ⅰ.Introduction of technical achievements and products

The surface treatment process of aluminum is the key link to determine the quality of aluminum. The surface treatment technology of aluminum alloy plays a very important role in the surface treatment of aluminum alloy. It can be said that the effect of the surface treatment of aluminum alloy is largely determined by the pretreatment of aluminum alloy.

Traditional surface pretreatment processes such as oil removal, alkali washing and light removal have long process flow, complex operation and high cost. So the three in one pretreatment process emerged at the right moment, namely kneading oil, alkali washing, light as one, can be directly oxidized after washing, not only simplify the process process, but also save cost, deeply favored by aluminum manufacturers, but also can be used as spraying pretreatment oil removal.

But the common three-in-one process has several drawbacks:

(1) It is easy to cause obvious spots on the surface of aluminum after incomplete alkali washing due to oil removal;

(2) The surface of aluminum with complex alloy composition is easy to form yellowish attachment;

(3) the surface brightness of aluminum after treatment is not enough;

(4) Relatively high cost consumption.

With the rapid development of aluminum processing industry and the fierce competition of aluminum industry, the market has higher and higher requirements for aluminum quality. The processing effect of the traditional common three-in-one processing technology can not meet the demand of the market, and can not adapt to the high requirements of aluminum processing technology.

In view of the current development situation of aluminum processing industry, it is imperative to develop a new three-in-one processing technology. According to the defects existing in the current common three-in-one treatment agent, the new three-in-one low-temperature polishing agent must have the characteristics of strong decontamination ability, high surface brightness of aluminum, good treatment effect on different components of aluminum, and low treatment cost. We are on the basis of inorganic acid and adopt the high performance the surface activity of emulsifying agent, the environmental protection low COD compound organic acids, special compound corrosion inhibitor, complexing agent, brightener, and acid fog inhibitor and other scientific distribution, improve the oil removal effect, enhances the aluminum surface brightness, reducing the corrosion of aluminum and drug costs, to achieve the oil removal effect is good, high brightness, And the purpose of environmental protection, and can adapt to different alloy components of aluminum, has a good market prospect and use value, can be used for oxidation coloring before treatment, can also be used for spraying before treatment.

Product features and advantages:

1) Excellent chemical balance performance, good oil removal effect, simple process control, stable quality, increase the use efficiency of tank liquid, long service life;

2) More environmentally friendly low COD compound organic acid, easy biodegradation, reduce pollution to the environment, in line with the trend of environmental protection;

3) Special compound corrosion inhibitor with special properties can moderately inhibit aluminum corrosion in the process of treatment and reduce aluminum consumption.

4) Through etching, it can quickly and fully loosen, dissolve and remove the natural oxide film and oil stains of aluminum, improve the processing speed and simplify the operation process. After the treatment of aluminum has a clean and bright surface, after washing can be directly anodized or skin film treatment, shorten the process, improve quality, reduce the cost of treatment; So as to achieve the purpose of removing oil, alkali erosion, polishing three in one;

5) Suitable for aluminum alloy products with complex alloy composition, can obtain bright surface.

Ⅱ.Product characteristics and technical indicators

Process maintenance management:

1. Control and supplement three-in-one low-temperature polishing agent according to process parameters or test results in the production process, and require each production shift to adjust the minimum two times according to the test results to ensure the degreasing effect;

2. The processing time of newly-built tank liquid can be shortened accordingly. If the tank liquid is used for a long time or has a large processing capacity, the impurities in the tank liquid can be removed and replenished again to meet the above technological parameters.

3. During the operation, try to avoid bringing in too much dirty debris to pollute the tank liquid. It is recommended to clean the tank bottom once every six months.

Refer to the consumption

Three in one low temperature polishing agent 3 ~ 6kg/T aluminum profiles (500 ~ 550m2/T aluminum profiles for reference).

Packaging, storage and transportation

25kg plastic drum sealed packaging, storage and transportation, heat, sun.

Ⅲ.Project product application field, market prospect analysis and environmental assessment analysis

It is mainly used for the spraying pretreatment of aluminum alloy building profiles and other aluminum products. It is one of the raw materials that must be used in the production of aluminum profile factory. Every ton of aluminum needs about 3 ~ 6 kg low-temperature polishing agent. The market demand is large and the application prospect is broad.

Aluminum alloy environmental protection low temperature polishing agent production raw materials are low toxic common chemical raw materials, production process without sewage, waste gas, waste residue discharge, will not cause pollution to the environment.

Ⅳ. Analysis of technical and economic benefit of project industrialization and industrialization production conditions

Aluminum alloy environmental protection low temperature polishing agent gross profit of ¥1500-2000 yuan per ton, raw material market is easy to buy, mass production to form a scale, has good economic benefits.

Aluminum alloy environmental protection low temperature polishing agent production equipment and process is relatively simple, mainly mixing drum and peripheral equipment, simple packaging equipment, equipment investment is less, the production process is easy to master. Production plant warehouse 50~100 square meters.

Ⅴ.Methods of technology transfer and cooperation

Aluminum alloy environmental protection low temperature polishing agent production technology one-time technology transfer, provide a full set of technical formula, production process, equipment list and raw material manufacturers, construction specifications, etc. Can study in my company, on-site training, learn so far. Engineers can also be sent to provide on-site technical services to guide the production of qualified products.
