1. Apps of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a given strain, temperature and time for changing all-natural rubber into more resilient components by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) in between person polymer chains. Vulcanized supplies are much less sticky and have superior mechanical houses. And vulcanization autoclave is utilised widely for this chemical approach. The major items are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this discipline, CZPT has been the leader, as we have accrued complete vulcanization experience and engineering for numerous several years.

3. CZPT Attribute and Functioning Procedure

3.1. CZPT Feature
Autoclaves with direct steam: heating and pressurization are carried out with steam. This heating technique is notably effective and indicated for goods of huge sizes and weight. The temperature uniformity which typically differs in between ±2°C,the exchange potential, taking place with condensation on colder surfaces, coupled with examined installations, enable to obtain excellent final results.

• CZPTally operated door opening and closing. It is controlled by PLC program.
• The seal ring is produced of silicon rubber.
• Safety pressure sensors have to stop doorway opening in situation of pressure (authorized much less than .1 bars).

4.3 Thermal Insulation Program
Interior Insulation and Exterior Insulation
We use ceramic fiber as the insulation material. The warmth transfer coefficient is extremely low to make the warmth decline to a bare minimum. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and appears great. Inside insulation design can get a minimal strength usage, although exterior insulation layout gets a higher one, but a greater temperature uniformity.

• Insulation:Internal insulation layer
