Applications of SINOMAC Vulcanization Autoclave
Rubber vulcanization is a chemical process at a presented stress, temperature and time for converting natural rubber into much more durable materia EPT by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) between person polymer chains. Vulcanized materia EPT are less sticky and have exceptional mechanical houses. And vulcanization autoclave is utilized widely for this chemical method. The principal merchandise are galoshes, rubber tubes, cable, rubber roller, rubber ball, and many others.In this area, SINOMAC has been the chief, as we have accrued entire vulcanization encounter and technological innovation for many many years.

3. EPT Attribute and Doing work Process

three.1. EPT Characteristic
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating system is particularly effective and indicated for items of massive sizes and excess weight. The temperature uniformity which generally may differ in between ±2°C,the trade ability, happening with condensation on colder surfaces, coupled with analyzed installations, permit to obtain excellent benefits.
