How to quickly establish DIN6701/EN17460 bonding system

The DIN6701/EN17460 standard is the general guideline for the construction of adhesive systems in the rail transit industry. The establishment and operation of the DIN6701/EN17460 adhesive system includes the following steps:

1、 Determine application scenarios and bonding requirements: Firstly, it is necessary to clarify the object of bonding, the purpose of bonding, and the conditions of bonding, such as the type of material to be bonded, the usage environment after bonding, and the durability requirements of bonding.

2、 Personnel training: Bonding is a special process, and the system has specific requirements for personnel involved in bonding. They need to have professional knowledge and operational skills in adhesive use, and at the same time, personnel should be sufficient and cover the entire bonding process to provide support for subsequent bonding production.

3、 Prepare a suitable bonding site: The use and curing of adhesives often require specific environmental conditions, so it is necessary to construct a suitable bonding area, control the environmental conditions of the bonding site, such as temperature, humidity, and light, etc., and divide each functional area according to the bonding process to prepare bonding materials.

4、 Choose the appropriate adhesive: Based on the application scenario and bonding requirements, select the appropriate adhesive and verify it; It is necessary to consider the properties of the adhesive, such as viscosity, curing time, bonding strength, temperature resistance, corrosion resistance, etc.

5、 Surface treatment: Pre treat the bonded surface according to the bonding requirements, such as cleaning, polishing, sandblasting, coating with primer, etc., to increase the bonding area and bonding strength.

6、 Apply adhesive: Mix and stir the selected adhesive according to the instructions, and then evenly apply it to the surface that needs to be bonded.

7、 Assembly and fixing: Assemble the components that need to be bonded according to requirements, and then fix them in appropriate ways such as fixtures, support frames, fasteners, etc.

8、 Curing and post-treatment: According to the characteristics and usage requirements of the adhesive, necessary curing and post-treatment should be carried out, such as room temperature curing, heating curing, pressure curing, etc.

9、 Quality inspection: Conduct quality inspections on the bonded components, such as visual inspection, non-destructive testing, mechanical performance testing, etc., to ensure that the bonding quality and performance meet the requirements.

In the construction process of DIN6701/EN17460 adhesive system, the following points should be noted:

1. Understand the properties and characteristics of adhesives, and choose suitable adhesives;

2. Treat the surface that needs to be bonded to ensure surface quality and cleanliness;

3. Master the correct methods and techniques for applying adhesives to ensure even application of the adhesive;

4. Choose appropriate assembly and fixing methods to ensure the stability and accuracy of the components;

5. Perform necessary maintenance and post-treatment to ensure bonding quality and performance;

6. Conduct quality inspection to ensure that the bonding quality and performance meet the requirements.

By following the above steps and precautions, an effective DIN6701/EN17460 bonding system can be established to improve bonding quality and performance, providing reliable assurance for product manufacturing and use.
