huanzhong how to maintain the maintenance of rubber joints
When the rubber joint is molded, it is pressed under high pressure and the cohesion of the elastomer cannot be eliminated. When the molded products are demolded from the mold, they often produce very unstable shrinkage (the shrinkage rate of rubber varies with the type of rubber), and it takes some time to calm down and stabilize.
 
Therefore, both the formula and the mold, rubber joints need to be carefully calculated and matched. Otherwise, it is easy to cause unstable product size and product quality degradation. Rubber is a hot-melt and thermosetting elastomer, while plastic is a hot-melt and cold-setting elastomer. Due to the different main types of vulcanization, the temperature range of rubber molding and vulcanization varies greatly, and is even affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber joints need to be moderately adjusted at any time. If not, the product quality may vary. In terms of preservation, they can be placed in a light-proof, cool and dry place, and away from things containing strong acids and alkalis.
 
When the rubber joint is not in use, you can apply some talcum powder on its surface. There is a layer of white powder on the bagged balloons and hairsprays you just bought. The white powder is talcum powder. Talcum powder is also easy to buy. It is economical and convenient, and it works very well.
