What is the phenomenon of excessive vulcanization of silicone tube?
![]()
The production of silicone rubber hose is an important process to be cured. The quality of the product is related to the length of the curing time. Below
The series will talk about the phenomenon of the silicone tube over curing will appear? As well as what caused it.
If the hose is seriously over vulcanized. Now the process of plastic steam curing, slow heating up, with the total volume of 85%. Warming up 2
Half an hour, then 151 degrees 2.5 hours, so what will be the quality of the problem? Have this experience to share a
Next, also can help me analyze. Need to have a certain ability to foresee problems of products. Now the problem is the color
Color tube color serious. The color of the tube is different, and the color is different. Some of the tubes are light colored in the middle of the
The spot stripes, which are consistent with the color of the surface. What terrible things could happen?
Shenzhen Qi Yu silicone rubber sharing: "2.5 hours of heating, and then 151 degrees 2.5 hours", which is what the use of rubber to do?
The general rubber, estimates should be scrapped. Curing time really long enough, the landlord will peel production hose test measured tensile properties to
Scrap is no, the life of the injury, there is a serious quality problems can not be avoided. Do tube, I have seen the temperature of 45 minutes
Curing 1.5 hours, you feel a little long. The heating time is so long, it should be the tonnage of the boiler is too small, the gas production is insufficient,
Will affect the quality of the product. Hard core tube, long slender canister. While the side of the side to allow workers to step on, loaded with full pedal, pass
Heat is also a problem. There will also be a non uniform of vulcanization. The outermost layer 100% serious over sulfur, the most intermediate tube sulfur to spend more than
Lighter, probably just, maybe it's a bit of a debt.
