What aspects should be noted in the summer and winter with the same silicone tube?
The formula of the same silicone tube products, due to the seasonal environment temperature, the reason for the general summer and winter formulations are inconsistent. Two
The distinction between them, I generally in the amount of accelerator and curing machine to adjust, the amount of summer is less than the amount of winter. Ignorance
How do we do it!
Because we have encountered a similar situation in the refining of nitrile rubber: winter the good performance of the formula to summer coke burning time
Short, extrusion products cured rubber particles or ranging from the size of the tumor, and the influence of the surface quality of the products and to lag is
The comprehensive quality problem is now taken to reduce the amount of accelerator and curing agent, in order to extend the coke burning time,
At the same time, it is also not very much to ensure that the timing of the curing process, to ensure the stability of extrusion process and production efficiency! Practice has proved
, the effect is good!
Summer is mainly considered scorch and summer scorch time to long point, to prevent the rubber mixing process in curing or Chu Cunzhong sulfide.
Formula collocation proper words generally do not have any problems our formula does not have the points we now also encountered this situation, the winter with
Our performance is very good, these days, shorter scorch time, extrusion is cooked, to deal with more headaches. If formula design
Reasonable words can also be no season. To reduce the cost of a fast curing formula, it is easier for those who are to take the cost.
Said the problem.
Anyway, we due to constraints, air conditioning room is not large enough, when large orders and delivery period short, rubber more
In general, no cooling measures directly stored in the room, so easily lead to shorter scorch time. If there is no
The effect of temperature control and storage, the formula of summer and winter is necessary to adjust. Otherwise, this kind of weather is not to mention the coke burning. I have a plus
The effect of the anti coke CTP 0.5 is also can be, but it is not as good as the adjustment of the formula of the curing system. Reduce the amount of accelerator and curing agent
To extend the focal burn time, the formulation of the property will certainly be affected, the degree of crosslinking will be reduced, TB will certainly be reduced, T90 will be extended
Wait
Any adjustment, the number of things will be affected by the nature of the impact, as long as the impact is still within the scope of customer requirements. In addition to
A small series of adjustment methods, appropriate to add some anti coke agent, or switch to some of the more slow speed of the accelerator can also be ah. No matter what kind of tone
The whole method, or that sentence: as long as the process of achieving the purpose and nature of the customer is still within the scope of the line, is a feasible way
