Compared with traditional phosphating treatment, electroplated silane treatment for electric heating tubes has the following economic advantages:

With the development of society and the improvement of industrialization, the quality requirements for products are also increasing. Metal surface treatment, as an effective method for protecting steel and non-ferrous metal products, is being widely used.

Silanized metal surface treatment is an environmentally friendly metal surface protection technology that has emerged in recent years. Compared with traditional phosphating methods, it has the characteristics of low energy, high efficiency, and environmental friendliness, and has initially shown excellent performance in industry, gradually replacing traditional phosphating technology.

Compared with traditional phosphating treatment, silanization treatment has the following economic advantages:

(1) Compared with traditional phosphating treatment, the silane based metal surface treatment process is more convenient to use and easy to control. It only needs to control the pH value and conductivity, eliminating the need to adjust many parameters such as free acid, total acid, promoter, zinc, nickel, manganese content, and temperature for phosphating. Silane treatment does not have surface adjustment, passivation, and water washing processes, Fewer production steps and shorter treatment times help improve the factory's production capacity, reduce wastewater discharge, reduce environmental pollution, and lower production costs.

(2) In terms of usage temperature, traditional phosphating generally requires temperatures ranging from 35 ℃ to 55 ℃ or even higher, while the silane film forming process is a chemical reaction at room temperature. Therefore, in daily use, the tank solution does not need to be heated to achieve the ideal treatment effect. Compared with phosphating treatment, it saves a lot of energy and reduces fuel exhaust emissions for application enterprises;

(3) The phosphating process requires the addition of nitrite promoter to produce nitrite and its decomposition products, which pose a threat to human health. There is no precipitation reaction in the silylation reaction, so no sediment is generated in daily treatment, eliminating the problem of solid waste treatment in the pre-treatment process and effectively extending the tank liquid turnover cycle. If filters and ion exchangers are installed, they can be used in a closed cycle.

(4) In terms of tank dosage, silanization also reduces by 20% to 50% compared to phosphating, and more importantly, the consumption of silanization per square meter is 15% to 20% of traditional phosphating. Silanization also significantly shortens the processing time compared to phosphating, thereby improving productivity and reducing equipment continuous operating costs.

(5) In addition to the advantages of silane metal surface treatment process, the electrodeposition silane metal surface treatment process can also achieve controllable preparation of silane film structure by adjusting the electrochemical parameters of the deposition process.

(6) By simply modifying the existing phosphating treatment equipment and investing a small amount of funds, the phosphating metal surface treatment production line can be converted into a production line for silanization and electrodeposition silanization metal surface treatment.
