1. Purposes of CZPT Vulcanization Autoclave
Rubber vulcanization is a chemical process at a presented force, temperature and time for changing normal rubber into a lot more durable components by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) between specific polymer chains. Vulcanized components are significantly less sticky and have outstanding mechanical homes. And vulcanization autoclave is utilised widely for this chemical process. The main goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, and many others.In this discipline, CZPT has been the chief, as we have gathered full vulcanization encounter and technological innovation for several several years.

three. CZPT Function and Functioning Method
three.one. CZPT Feature
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating program is notably effective and indicated for goods of massive sizes and excess weight. The temperature uniformity which usually differs in between ±2°C,the exchange ability, occurring with condensation on colder surfaces, coupled with tested installations, allow to obtain excellent final results.

four.2 CZPT System
- The closing program of the autoclave is the indented kind assisted with a hydraulic method, in order to quickly and secured make a totally airtight closing.
- The entire method is made up of 3 elements: a pair of equipment flange, pushed devices and seal ring.
- CZPTally operated doorway opening and closing. It is controlled by PLC technique.
- The seal ring is produced of silicon rubber.
- Protection stress sensors have to avoid doorway opening in case of stress (authorized much less than .1 bars).
4.3 Thermal Insulation System
Internal Insulation and Exterior Insulation
We use ceramic fiber as the insulation content. The heat transfer coefficient is very minimal to make the warmth decline to a least. The covering board of ceramic fiber is stainless steel. It is corrosion resistant and seems nice. Internal insulation design and style can get a reduced strength consumption, even though exterior insulation design will get a substantial 1, but a better temperature uniformity.
