With the development of adhesive technology, the number of adhesives has increased. Adhesives are widely used for equipment maintenance due to their good performance, ease of use and fast use, good adaptability, and good economic advantages. The following adhesive manufacturers mainly discuss the application of acrylic glue in equipment maintenance.

Surface chemical structure

The chemical composition and structure of the surface of the bonding material have an important influence on the bonding performance, durability, heat aging performance, etc .; the effect of the surface structure on the bonding performance is usually changed by changing the cohesive strength, thickness and porosity of the surface layer, And surface free energy. Among them, the surface chemical structure can cause changes in the physical and chemical properties of the surface and changes in the cohesive strength of the surface layer, and therefore has a significant effect on the adhesion properties.

2. Bonding process

The acrylic adhesive bonding process mainly includes joint design, surface treatment, lamination and coating, curing and quality inspection.

3. Use glue

For one-component adhesives, no preparation is required and they can be used directly. For two-component or multi-component adhesives, the quality of the adhesive will directly affect the adhesive performance of the adhesive, and each component must be accurately weighed. No more than 2% ~ 5%) and stir well? The amount of adhesive should be based on the amount of paint used up within the validity period?

4. Choice of adhesive

Adhesives can be divided into two categories: organic and inorganic. Organic binders include synthetic organic polymer binders and natural organic polymer binders. Synthetic organic polymer adhesives, such as modified high-strength resin oxygen rubber, silicone rubber, polyurethane, modified acrylic, etc.

When selecting an adhesive in equipment maintenance, the properties of the adhesive, the nature of the material to be adhered, the shape structure and process conditions, and the load form (tensile force, shear force, peeling force, etc.) should be comprehensively considered. . ) The bonding site, as well as the cost and operating environment. Factors in choosing the best adhesive to meet specific needs.
