1. Preparation: First, ensure that the working area is clean and tidy, and avoid impurities from affecting the bonding effect. Then the epoxy resin adhesive is divided into two parts, A and B, and mixed in proportion. Usually, the ratio of A to B is 1: 1, but the specific ratio needs to be determined according to the product specification.
2. Stirring and mixing: Pour part A and part B epoxy resin glue into a clean container, and fully stir with a special stirring rod or stirrer. Generally, the stirring time is 2-3 minutes until the two parts are completely and evenly mixed and the color is the same.
3. Coating or injection: coating the mixed epoxy resin glue on the surface to be bonded, or injecting it into the part to be bonded with a syringe. Note that the coating or injection should be uniform and continuous to avoid bubbles or gaps.
4. Bonding: Put the two parts that need to be bonded together according to the design requirements, and make them closely fit with appropriate pressure. According to the characteristics of epoxy resin adhesive, it usually takes some time to cure. During the curing process, clamps or other fixing devices can be used to keep the bonded parts stable.
5. Curing: according to the curing time and environmental conditions of the epoxy resin adhesive, wait for a certain time to completely cure the epoxy resin adhesive. The curing time is generally 24 hours, but the specific time should be determined according to the product specification.
6. Post-treatment: After the epoxy resin adhesive is completely cured, post-treatment can be carried out, such as painting, polishing and painting. According to the specific needs, choose the appropriate method to deal with it.
It should be noted that the use of epoxy resin adhesive should follow the instructions and precautions in the product manual. During use, pay attention to safety and avoid contact with skin and eyes. In case of accidental contact, rinse immediately with clean water and seek medical attention in time. In addition, epoxy resin adhesive will generate heat during curing, so it should be avoided to be used in a closed environment to avoid fire.
