Transfer production technology of Chemicals used for anodizing surface treatment of aluminium alloy profiles

Ⅰ.Brief introduction of technical Achievements

Project Background:

Since the middle of the eighties, China's construction aluminum industry has grown from nothing, from small to large, and now it has become a big country of aluminum production and aluminum profile in the world. According to incomplete statistics, primary aluminum output will reach 8.419 million tons in 2020, accounting for 35.7 percent of the world total, and exceed 8.5 million tons in 2021, while aluminum profiles will reach 5.31 million tons in 2020. Today, its annual output has doubled, and its production capacity and actual annual output are the first in the world.

With the rapid development of China's economy and the continuous heating of the construction and real estate market, people's demand for high-grade building decoration materials will be more and more large, and the construction aluminum profile will have a broader market space.

In the production process of building aluminum profile, the development and update of surface treatment technology is particularly rapid, regardless of the variety of surface treatment technology. The level of technology and product quality, or the level of equipment have developed to a new stage, has covered anodizing. Electrolysis coloring. Electrophoretic coating. Colorful powder spraying, liquid phase fluorocarbon spraying and other surface treatment methods, complete technical categories, varieties rich and colorful.

At present, China's building aluminum profile surface treatment processing, anodizing. Electrolysis coloring. Electrophoretic coating process accounts for about 50% of the construction aluminum profile market, and is still the main surface treatment production process in China. Electrophoretic paints are still based on transparent acrylic anodic electrophoretic paints, matte electrophoretic paints and color electrophoretic paints have also been used. Powder spraying because of environmental protection and pollution-free, in recent years, colorful powder spraying aluminum profile development is the fastest, currently has occupied more than 45% of the market. In the economically developed Yangtze River Delta and Pearl River Delta region, powder spray profiles have occupied nearly half of the market share of construction aluminum profiles. Therefore, high-grade building aluminum profile has a broad market prospect.

Ⅱ.Introduction to series products

In order to overcome the shortcomings of the surface performance of aluminum alloy, improve the protection, decoration, function, expand the scope of application, prolong the service life, aluminum alloy surface treatment technology is an indispensable part of the production of architectural aluminum profiles. The series of surface treatment chemicals supporting the surface treatment process of aluminum alloy are indispensable raw materials in the production.

At present, there are three main series of aluminum alloy surface treatment additives developed by us:

1. Oxidation coloring additive series: Mainly include high efficiency AC degreasing agent, low temperature polishing agent, solid (or liquid) acid etching sand surface agent, solid (or liquid) long life alkali etching agent, neutralization (stain removal) agent, wide temperature rapid oxidant, Imitation stainless steel champagne colorant, titanium gold colorant, K gold colorant, golden yellow colorant, imitation copper colorant, normal temperature sealing agent, medium temperature sealing agent, high temperature sealing agent, environmental protection low temperature nickel free fluorine free sealing agent, triacid (high temperature) polishing additive, no yellow tobacco acid (high temperature) polishing additive, etc.

2. Electrophoretic paint series products: mainly include universal high gloss anodic acrylic electrophoretic paint, general energy-saving low temperature curing anodic acrylic electrophoretic paint, extinction anodic acrylic electrophoretic paint, color anodic acrylic electrophoretic paint and pearlescent electrophoretic paint, etc.

3. Colorful powder coating series products: mainly include high-efficiency AC oil remover before spraying, golden chrome skin film agent, environment-friendly golden chrome free skin film agent, epoxy colorful powder coating, epoxy polyester colorful powder coating, acrylic colorful powder coating, polyurethane colorful powder coating, etc.

Ⅲ.Application field, market prospect and industrial production conditions of project products

Aluminum alloy surface treatment additives series is mainly used in aluminum factory workshop oxidation coloring electrophoresis and surface treatment workshop, with the rapid development of architectural aluminum production, become the world's aluminum production capacity of the highest in our country, the necessary auxiliary materials for production, will also have a larger market demand, market prospect.

Production conditions and plant water and electricity equipment:

(1) Production of oxidation coloring additives requires 50-80 square meters of production site, 50-100 square meters of warehouse, storage of raw materials and products, 20-30KW three-phase power supply, convenient water.

(2) Personnel and working capital:

There are 2-3 operators and 1 technician. The start-up capital is 200,000-300,000 yuan. The more the operation is, the easier it will be.

Ⅳ.Analysis of technical and economic benefit of project industrialization and environmental evaluation

According to our detailed accounting, the total investment of the project is about 1 million yuan. If the annual output of aluminum alloy surface treatment auxiliaries is 1000 tons, the annual output value is about 15 million yuan, and the annual gross profit is about 7 million yuan. Deducting industrial and commercial tax, factory rent, water and electricity and other management expenses, the annual economic benefits are still considerable.

Aluminum alloy oxidation coloring surface treatment additives in the production process, because they are only normal temperature ingredients, mixing. No waste gas and waste water polluting the environment. Small amount of cleaning water, simple treatment can be discharged, will not cause pollution to the environment.

Ⅴ.Methods of technology transfer and cooperation

One-time technology transfer, provide a full set of technical formula, production process, equipment list and raw material procurement 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. At the same time, we can provide a complete set of solutions such as plant and equipment selection, how to promote the market, raw material procurement, how to make color plate, how to reduce production cost and improve production efficiency, so that you can put into production in the shortest time and make profits quickly. You can change the formula as needed. And a professional engineer consultant, can long-term tracking technical guidance, remove worries.

Detailed project feasibility analysis report on request.

Product technology for large-scale production of mature technology, technology transfer fee call to discuss.
