The difference between the silica gel tube and the structural difference
![]()
Xiaobian always felt that is hydrogen silicone tube of thixotropy and structured is a principle, perhaps not the same name is caused by white carbon black
The function of the key is to destroy, and the recovery is all the time. Perhaps they form hydrogen bonds in different parts of the bond.
The main types are different? After all, the thixotropy of two hours on the line, structured time or much longer.
Silicone tube structured and thixotropy, individually, is completely different, but for white carbon black does have close correlation.
And the hydrogen bond related to the small series. If the silica treated, can not appear even in the silicone tube is structured, but
There is still another thixotropy,
Not to mention two add ratio difference is too large, even in the winter, use this to illustrate there is no structured, too far fetched polyether.
Silicone oil will not lead to the structure of silicone tube, in a certain proportion of the addition, the polyether silicone oil will not lead to structured, but more than
This range will lead to a structured speed.
Qi Yu silicone hose manufacturers to share: in fact, the principle is very similar, but due to the system viscosity difference is larger, thixotropic system
Viscosity is generally much smaller than that of silicon rubber system, so the time difference is very big, thixotropic may a few seconds can be restored, but
Structured to for a long time, also not only white carbon black can increase in thixotropy and some other additives can also, thixotropic recovery
Time is generally short.
