1. Surface treatment: This is a key step in our successful repair. After determining the repaired part, remove the dirt on the surface and clean it with industrial alcohol or acetone. The cleaning area should be larger than the surface to be cleaned, so as to avoid re-contamination of the clean surface. Then use a sandblasting gun, hand grinding wheel, angle grinder, etc. to roughen the surface, and it should be bonded immediately after cleaning and drying again.
2. Glue distribution: The domestic series of glass-lined repair agents are in the form of two-component glue, A is the main material (large box), B is the curing agent (small box), the ratio of A and B should be strictly followed, and the product use ratio ratio (volume ratio 5:1, weight mixing ratio 3:1). The amount of glue to be mixed can be determined according to the applicable period, season, construction conditions and actual dosage of the rubber species, and the amount of glue to be blended at one time can be adjusted as much as possible. Mixing tools are strictly prohibited, and tools must be cleaned before use. When mixing and adjusting the glue, it should be continuously stirred and rolled to make the two different colors fully mixed into one color. After the glue is adjusted, it should be used up within the specified time. The glue mixing place should be ventilated, dry and clean.
3. Glue: The thickness of the glue layer should not exceed 20mm at most. First apply a small amount on the surface to be repaired, press repeatedly with a tool to fully infiltrate the surface to be repaired, and then apply a large amount. In order to prevent bubbles and pores from remaining in the adhesive layer, try to move in one direction and apply a certain pressure when applying the adhesive. Do not move too fast. The method of gluing depends on the selected product. , scraping and other methods. If it needs to be machined after curing, be sure to leave a margin.
