The most important is the quality problem for silicone products industry, and the quality problem of silicone tube is mainly reflected whether there are bubbles in the silicone tube hardness and silica gel. Hardness is small make up about in the article, Xiaobian to tell today is to solve the silicone tube bubble problem?
First of all, silica gel tube air bubbles problem the main reason mainly has 2 kinds of possible.
1 raw material problems: estimation of transparent white carbon black impure, ormixed with other white carbon black
2 coking problem: rubber mixing uneven, filling capacity is not reasonable, the discharge temperature and time have no control
Then, the silicone tube bubbles cause of the problem has been to find out, whatsolutions? The solution is to suit the remedy to the case.
Since the raw material problems, then choose transparent white carbon blackpurity good point, kneading machine clean after mixing transparent adhesivematerial.
Since the coking problem, so good control of temperature control kneading,kneading time in the original kneading time extended for another 5-10 minutes,and then glue discharging test.
In short, the silicone tube quality and raw materials, but also related to the technology and silica gel products factory. Hope the above method for all action.
