one. Applications of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a given pressure, temperature and time for changing normal rubber into more tough supplies by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst person polymer chains. Vulcanized supplies are less sticky and have excellent mechanical qualities. And vulcanization autoclave is used widely for this chemical approach. The major products are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this area, CZPT has been the leader, as we have gathered full vulcanization experience and technology for many many years.

4.3 Thermal Insulation Method
Internal Insulation and Exterior Insulation
We use ceramic fiber as the insulation materials. The warmth transfer coefficient is extremely low to make the heat decline to a minimum. The masking board of ceramic fiber is stainless metal. It is corrosion resistant and looks good. Inside insulation design can get a low energy consumption, even though external insulation layout will get a large one, but a much better temperature uniformity.
