1. Purposes of CZPT Vulcanization Autoclave
Rubber vulcanization is a chemical process at a offered strain, temperature and time for changing all-natural rubber into a lot more sturdy materials by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst person polymer chains. Vulcanized materials are considerably less sticky and have excellent mechanical houses. And vulcanization autoclave is used commonly for this chemical process. The major products are galoshes, rubber tubes, cable, rubber roller, rubber ball, and many others.In this subject, CZPT has been the chief, as we have accrued total vulcanization experience and technological innovation for numerous years.

3. CZPT Function and Functioning Method
three.1. CZPT Function
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating program is particularly effective and indicated for merchandise of big sizes and bodyweight. The temperature uniformity which typically varies amongst ±2°C,the trade capacity, transpiring with condensation on colder surfaces, coupled with examined installations, permit to obtain excellent benefits.

4.2 CZPT System
- The closing technique of the autoclave is the indented kind assisted with a hydraulic program, in purchase to quickly and secured make a absolutely airtight closing.
- The total method is made up of three components: a pair of equipment flange, pushed devices and seal ring.
- CZPTally operated doorway opening and closing. It is controlled by PLC method.
- The seal ring is produced of silicon rubber.
- Security stress sensors have to stop door opening in circumstance of pressure (authorized significantly less than .1 bars).
4.3 Thermal Insulation Program
Internal Insulation and External Insulation
We use ceramic fiber as the insulation materials. The heat transfer coefficient is extremely lower to make the heat decline to a minimal. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and seems great. Inside insulation design and style can get a reduced vitality usage, while external insulation design and style gets a high one particular, but a better temperature uniformity.
