A rubber seal vulcanization process, what reason can cause poor rubber sealing ring features? Such as: rubber seal vulcanization work didn't have enough time or sulfide operating temperature is unqualified, namely sulfide levels is not enough (also called owe sulfur), the physical properties of the sealing of goods were not done, such as low intensity, low compressive strength, elongation, deformation, ductility and other properties can not be normal give full play to the advantages, the levels are highly correlated with less sulfur.

The whole process of silicone seal rubber, what reason causes the silicone seal characteristics of weak? , such as silica gel seal vulcanization rubber work fewer hours or vulcanized rubber working temperature does not pass, which is lack of vulcanized rubber level (also called owe sulfur), the product process in sealing performance is no guarantee, such as low low compressive strength, tensile strength, tensile strength, large deformation and plasticity characteristics cannot normal make full use of advantages, this level and less sulfur existence very big relations.

Little imagine, if the curing time is too long or too high sulfur (alias), and the physical properties of the rubber seal is reduced, harm to the hydraulic seal material plastic properties. Afterwards according to the concept of vulcanization curves of check, if accompanied by the extension of time, the torque has been rising trend, so a sulfur plastic strength than is sulfide communication is big, if accompanied by the extension of time, there is a downturn in the torque that can show had caused plastic unscramble the sulfur chemical crosslinking, and poor chemical/cib appear loose and sticky situation. You need to do a good job of the improved immediately, to prevent this kind of thing.

Therefore sulfide this whole process is very important, it will cause the characteristics of the rubber sealing ring is unqualified, so that can not be applied or could shorten, etc.

The whole process of silicone seal rubber, what reason causes the silicone seal characteristics of weak? , such as silica gel seal vulcanization rubber work fewer hours or vulcanized rubber working temperature does not pass, which is lack of vulcanized rubber level (also called owe sulfur), the product process in sealing performance is no guarantee, such as low low compressive strength, tensile strength, tensile strength, large deformation and plasticity characteristics cannot normal make full use of advantages, this level and less sulfur existence very big relations.

But don't know if vulcanized rubber's time is too long or too high sulfur (nickname), silicone seal process performance to reduce, raw material plastic grain characteristics damage the seals. Later can on the basis of vulcanized rubber trend diagram observation, if with the increase of the time, the torque has been sustained growth trend, then a plastic grains than the compressive strength of sulfur is vulcanized rubber communication is big, if with the increase of the time, there is a downturn in the torque so that sulfur, lead plastic granule on excess chemical crosslinking, and chemical cross-linking cib will loose, sticky poor condition. We need to do a good job to improve immediately, to avoid this kind of thing.

Thus vulcanized rubber this whole process is very important, it will lead to the silicone seal features don't pass, so that the cause can't use or shorten the service life, etc.
