1. Programs of CZPT Vulcanization Autoclave
Rubber vulcanization is a chemical process at a presented stress, temperature and time for changing normal rubber into much more tough components by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst personal polymer chains. Vulcanized supplies are less sticky and have outstanding mechanical properties. And vulcanization autoclave is utilized broadly for this chemical process. The major goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this subject, CZPT has been the chief, as we have amassed full vulcanization encounter and engineering for several a long time.

3. CZPT Characteristic and Operating Approach
three.one. CZPT Characteristic
Autoclaves with direct steam: heating and pressurization are carried out with steam. This heating technique is especially effective and indicated for items of huge sizes and fat. The temperature uniformity which normally may differ between ±2°C,the exchange potential, occurring with condensation on colder surfaces, coupled with tested installations, allow to obtain excellent outcomes.

four. Equipment CZPT Particulars
four.1 Pressure Vessel
CZPT Force Vessel with fast-opening door, can be licensed to:
- CHINESE STHangCZPTRD, GB150-2011
- AMERICAN STHangCZPTRD ASME SEC VIII DIV.one with ASME Certificate
- EUROPEAN STHangCZPTRD PED ninety seven/23/EC with CE certification.
four.2 CZPT System
- The closing technique of the autoclave is the indented kind assisted with a hydraulic program, in buy to rapidly and secured make a totally airtight closing.
- The entire system consists of three areas: a pair of equipment flange, pushed units and seal ring.
- CZPTally operated door opening and closing. It is managed by PLC technique.
- The seal ring is produced of silicon rubber.
- Protection force sensors have to prevent doorway opening in situation of strain (authorized significantly less than .1 bars).
4.3 Thermal Insulation Program
Inner Insulation and Exterior Insulation
We use ceramic fiber as the insulation substance. The warmth transfer coefficient is really lower to make the warmth reduction to a bare minimum. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and seems wonderful. Inner insulation design and style can get a minimal power intake, even though external insulation design and style gets a substantial a single, but a far better temperature uniformity.
- Insulation:Internal insulation layer
- Insulation substance:Ceramic fiber
- Exterior sheet metallic: stainless metal,one. mm
- Insulation thickness:100mm
four.4 Heating Program
- The heating method is a oblique steam type.
- The oblique technique will be via stainless-steel or copper tubing type heat exchanger put on the rear aspect of the autoclave amongst fan and items. The stream have to transfer from content to enthusiast, then go front doorway employing vessel facet to content
- Heating Exchanger material :304 Stainless-steel with aluminum fin or copper tubing aluminum fin
- Heating Exchanger sort: Multi-row finned tubing
4.five Air Recirculating Technique
- Scorching air circulating duct
Annular air-duct placed on the two facet of the autoclave inside as the CZPT air delivery method. This style attributes make the temperature a lot more uniform, and doing work area a lot more massive.
- The Motor fan for circulation
The motor is bolted to the rear of the autoclave, it drives the supporter right.
- Parameters of circulating admirer
Electrical power:eighteen.5KW,six-pole, 3phase
Rated rotate speed:960r/min(380V/50HZ)
Enthusiast wheel:seven# centrifugal impeller(Diameter:700mm),
Flow rate:12800 M3/h.
- Shaft sealing
Working with drinking water cooling to guarantee a long life, the shaft drinking water cooling with separate drinking water pump and flow change to be fitted to check drinking water movement and immediately alarm/quit the cycle if there is not sufficient drinking water movement.
four.six Temperature checking components
Temperature thermocouples: 2 pcs, K sort, such as HMI monitoring, info-acquisition and manage.
four.7 Pressure Factors
- Inlet and exhaust valve, proportionally managed, CZPT handle valve.
- Manual exhaust valve, three-piece ball valve.
- Strain transducer: 1
