的表面，有的在内部，而产生的原因则比较多，接下来小编来给大家一一说道 Various problems are encountered in the daily production process, and air bubbles are a more common problem. Some air bubbles are on the surface of rubber products , and some are internal. The causes are more, and the next is small. I'll edit it for everyone
The reasons are as follows:
、原材料本身的问题，原因既有可能是质量不好，也有可能是配方搭配问题，再或者是材料水分过多(可以在混炼时加点氧化钙来解决) ，建议厂家逐一排除， 1. The problem of the raw material itself may be caused by poor quality, formula mix, or too much moisture in the material ( can be added with calcium oxide during mixing ) , it is recommended that manufacturers eliminate them one by one.
、操作不规范，导致橡胶混炼的不充分或不均匀，这个问题可以通过完善作业指导书来规避，而完善、合规的作业指导书是橡胶制品厂家最基本的要求， 2. Irregular operation leads to inadequate or uneven rubber compounding. This problem can be circumvented by perfecting the work instructions, which are the most basic requirements of rubber product manufacturers.
、排气的问题，首先要排除加工过程中是否有设置排气的工艺，其次是模具本身问题，如果模具没有加排气槽、或排气孔设计不合理、再或者是异物堵塞，也会产生气泡 3. The problem of exhaust, first of all, to exclude whether there is a process of setting exhaust during the processing, and the second is the problem of the mold itself. If the mold does not have an exhaust groove, or the exhaust hole design is unreasonable, or the foreign matter is blocked, Will produce bubbles
4. Problems during vulcanization. If the vulcanization time is short and insufficient, the pressure during vulcanization is insufficient, or there are more impurities in the vulcanizing agent, bubbles will also be generated.
5. The product is too thick, which causes the heat transfer of the rubber to slow down. In the end, only the appearance is vulcanized, and the inside is full of air bubbles.
Some other suggestions
加工过程中注射材料速度过快也是产生气泡的重要原因。 1. The speed of the injected material is slowed down. The speed of the injected material is too fast during the process.
2. We know that air bubbles are caused by the entry of air. The solution is of course to prevent air from entering, so the more thorough method is to change the vulcanization molding machine to a vacuum molding machine.
