The surface treatment process of HEB140 European standard H-beam and IPB140 German standard H-beam steel is an important link in metal manufacturing and industrial applications. These two types of H-beams have similarities in structure and properties, but there are some differences in the surface treatment process. This article will introduce the surface treatment process of these two types of H-beam in detail and compare their advantages and disadvantages.
1. Surface treatment process of HEB140 European standard H-beam.
The surface treatment of HEB140 European standard H-beam mainly includes pretreatment, primer and topcoat coating. Pretreatment is to remove oil, rust and other impurities on the surface of the steel to ensure that the surface of the steel is smooth and clean. Primer coating is to apply a layer of anti-rust paint to the surface of the steel to improve the corrosion resistance and adhesion of the steel. Topcoat is applied to increase the aesthetics of the steel and protect the film.
In the surface treatment process of HEB140 European standard H-beam, it is generally coated by spraying or brushing. The spraying method has the advantages of high coating efficiency and uniform paint film, but it requires the use of a large amount of organic solvent, which causes pollution to the environment. Although the brushing method is environmentally friendly, the painting efficiency is low, and it requires a lot of manpower and time.
Second, the surface treatment process of IPB140 German standard H-beam.
The surface treatment of IPB140 German standard H-beam mainly includes phosphating treatment, primer and topcoat coating. Phosphating is the formation of a phosphate film on the surface of steel by chemical reaction to improve the corrosion resistance and adhesion of steel. The primer and topcoat are applied in a similar way to HEB140 European standard H-beam, but the specific coating materials and processes may vary.
In the surface treatment process of IPB140 German standard H-beam, phosphating treatment is generally carried out by impregnation or spraying. The impregnation method has the advantages of uniform treatment and high efficiency, but it requires the use of a large amount of phosphating solution, which causes pollution to the environment. The spraying method has the advantages of high treatment efficiency and material saving, but it requires the use of a large amount of organic solvents, which causes pollution to the environment.
3. Comparison of the surface treatment process of HEB140 European standard H-beam and IPB140 German standard H-beam.
The surface treatment process of HEB140 European standard H-beam and IPB140 German standard H-beam is basically similar in terms of pretreatment, primer and topcoat coating, but there are some differences in phosphating treatment. HEB140 European standard H-beam is generally pretreated by sandblasting or shot blasting, while IPB140 German standard H-beam is pretreated by pickling or mechanical sanding. In terms of phosphating treatment, HEB140 European standard H-beam is generally phosphated by impregnation or spraying, while IPB140 German standard H-beam is phosphated by pickling or mechanical sanding.
In addition, there are also differences in the environmental performance of HEB140 European standard H-beam and IPB140 German standard H-beam in the surface treatment process. Traditional methods such as spraying and impregnation require the use of large amounts of organic solvents or phosphating fluids, which pollute the environment. Therefore, when choosing a surface treatment process, its impact on the environment needs to be considered.
IV. Conclusions. The surface treatment process of HEB140 European standard H-beam and IPB140 German standard H-beam is basically similar in terms of pretreatment, primer and topcoat coating. However, there are some differences in phosphating treatment. In addition, there are also differences in the environmental performance of the two types of H-beams during the surface treatment process. Therefore, the environmental impact of the surface treatment process and the specific application needs to be considered when selecting it. At the same time, with the development of science and technology, more and more environmentally friendly surface treatment processes continue to emerge, providing more options and development directions for the surface treatment of H-beams.
