The rubber used in Jinan glue machine is mainly AB glue. AB gum usually has epoxy resin, silicone resin and polyurethane. When the glue is black or dark grey, the interior will be filled with fillers. Like epoxy resin, polyurethane is usually filled with silica gel A. If the proportion of silica gel is the same, it is filled with glue A and glue B.
There are many fillers, some silica powder, some quartz sand, some lime powder and other fillers have the function of heat conduction and heat dissipation, thus improving the hardness. But these fillers are very hard, and they deposit, that's the layer and glue. If coated with a layer, the performance of the glue will change, the density will change, leading to changes in proportion, resulting in the performance of the glue can not be used, the performance of the glue back is cured, the product washed out is not qualified.
How does Jinan glue machine prevent glue settlement?
1. Stirring function is added to the material barrel. After starting, the agitator will continuously rotate the agitator to prevent the settling of the agitator. In addition, stirring rods are more effective. If the stick is too short to reach the bottom, the glue will settle down.
2. Before pouring, open the plastic bucket, stir it with a stirring rod or drill, and then pour it into the bucket.
3. Can buy some high-quality glue, high-quality glue, filler is relatively small, particles are relatively fine, precipitation is not so serious.
4. Purchase glue close to the production date. The longer the glue stays, the more serious the deposition will be.
5. Better let the glue machine run every day. Please don't use it for long. If you haven't used it for a long time (for example, a week and a half), remove the glue from the bucket and rinse it with alcohol. Otherwise, glue will settle in barrels and pipes.
6. In order to prevent precipitation, the shorter the test tube, the better. The pipe is too long and glue deposits easily in it.
