Issuing time:2019/7/23 11:40:58

Many people think that they know a lot about rubber accessories! Actually, the understanding of rubber accessories is just a glimpse! So Xiaobian will introduce you to these contents!

Rubber is a hot-melt thermoset elastomer, and plastic is hot-melt cold-set. Because of the different types of sulfides, rubber has a considerable temperature range for molding and curing, and may even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber parts need to be adjusted at any time. If not, the quality of rubber parts may be different. The rubber parts are made of rubber raw materials and mixed with rubber, which is made of rubber. The rubber compound is designed according to the characteristics of the rubber parts required, and the required hardness of the product is determined. The product is molded and molded by a rubber flat vulcanizing machine. When the rubber parts are molded, after the large pressure is pressed, the cohesive force prepared by the elastic body cannot be eliminated, and when the mold is released from the mold, the extremely unstable shrinkage tends to occur, and it takes a period of time to be gentle and stable. Therefore, when a rubber fitting is designed, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, it is easy to produce rubber parts that are unstable in size.
