What are the reasons for the smaller proportion of silicone rubber tube?
![]()
The proportion of silicone rubber tube is generally refers to the proportion of the post curing, the recent problem of some customers asking about silicone tube in the production. Main problem is years before and after the silicone tube proportion suddenly becomes small, did not change the material number, operation conditions did not change, batching weight did not differ, test piece molding conditions did not change, homework personnel also did not change.
Well, this is strange! What is the cause? What are the methods to solve this problem? The analysis of odd and silicone rubber.
First of all, a look at the production of silicone tube production of the environment has not changed; two see, the production equipment is not a problem; three, the proportion of the test is accurate.
If the above is not a problem, then it may be the following reasons:
1 filler is added, mixed, and more than a few points (the same car).
2 dispersed.
3 the change of sulfide pressure. After the determination of the products, the proportion is good, but the test board is not good, confirmed that the test plate molding machine temperature difference, the pressure is not very high, is to re adjust.
In short, the wonder of silicone rubber from measuring and testing methods, the material is less or more with the point of view. Hope that the above will help you.
