Vulcanization is process of
converting natural rubber or rubber polymers into more durable and mechanically
strengthens rubber by the process of mixing sulfur and processing. This process
results in changing the cross-linking bonds within the natural rubber and
making bonds more strong and non-sticky.
Vulcanization curing is achieved by heating the natural rubber or rubber
polymer at very high temperature along with sulfur or any other agent, such
high level of temperature rise results into changing of bond within the rubber
and resulting in non-sticky, maker it lesser deformable when heated, and removes
the brittleness this helps rubber to achieve the desired level of elasticity.
Continuous Vulcanization curingprocess is most common process used for variety of application. In the process
Continuous Vulcanization curing rubber and accelerator is put under high
temperature and pressure, this mixture is passed through the continuous heating
line during the process, some of C-H bonds are replaced by chains of sulfur
atoms that link with a cure site of another polymer chain. These bridges comprise
amongst one and eight atoms. The number of sulfur atoms in the crosslink
strongly determines the physical properties of the final rubber article. Short
cross-links give the rubber better heat resistance. Desired level of heat can
be maintained by hot air heaters or microwave heaters.
Microwave heaters have proven
their self better than conventional hot air heating process. In the process of
continuous vulcanization when curing package is placed within the microwave
heaters then as compare to hot air heaters, microwave acts very quickly by
directly targeting inner moisture content within the rubber and this helps in achieving quick
results. Few of the other advantages those microwaves based continuous
vulcanization curing oven offers over conventional continuous vulcanization
curing oven are as follows:
1) Higher
rate of heat transfer
2) Faster
processed out
3) Better
quality of heating
4) Compounds
are formed properly
5) Microwave
heaters are compact as compared to conventional heater
6) No
wastage of energy

Industrial powder coating batch ovens are available in a broad range of conventional sizes to suit several applications (custom sizes are also available upon request). A powder curing oven application is the most acceptable option if you require powder curing applications. You may save time and money by lowering the rework needed by using our powder curing ovens designed to prevent powder from flying away. Industrial powder coating ovens employ a design that ensures the air is distributed uniformly down the length of the work area, resulting in higher-quality finishes and shorter cure periods.
ReplyDeleteGood informative and helpful blog on Microwave Continuous Vulcanization. I am the owner of TWIN Engineer’s Microwave heating technology, and this blog is very helpful for those people who are new in this industry or those who wants to start business regarding same.
