one. Applications of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a offered force, temperature and time for converting organic rubber into much more durable resources by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) among personal polymer chains. Vulcanized materials are much less sticky and have excellent mechanical properties. And vulcanization autoclave is employed widely for this chemical approach. The principal goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, and many others.In this area, CZPT has been the leader, as we have accrued complete vulcanization experience and engineering for numerous many years.

3. CZPT Feature and Working Process

three.one. CZPT Function
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating method is especially effective and indicated for merchandise of massive sizes and bodyweight. The temperature uniformity which normally may differ between ±2°C,the trade capacity, taking place with condensation on colder surfaces, coupled with analyzed installations, enable to obtain excellent final results.

four. Equipment CZPT Information

four.1 Pressure Vessel

CZPT Force Vessel with quick-opening door, can be accredited to:

  • CHINESE STHangCZPTRD, GB150-2011
  • EUROPEAN STHangCZPTRD PED ninety seven/23/EC with CE certificate.

four.2 CZPT System

  • The closing system of the autoclave is the indented sort assisted with a hydraulic program, in purchase to swiftly and secured make a totally hermetic closing.
  • The entire program is made up of 3 elements: a pair of equipment flange, driven units and seal ring.
  • CZPTally operated door opening and closing. It is managed by PLC program.
  • The seal ring is made of silicon rubber.
  • Safety force sensors have to prevent door opening in circumstance of force (allowed less than .1 bars).

4.3 Thermal Insulation System
Inside Insulation and External Insulation
We use ceramic fiber as the insulation content. The warmth transfer coefficient is very minimal to make the warmth loss to a minimal. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and seems to be great. Inside insulation design and style can get a minimal vitality intake, whilst exterior insulation style receives a large one particular, but a much better temperature uniformity.

  • Insulation:Internal insulation layer
  • Insulation materials:Ceramic fiber 
  • Exterior sheet metal: stainless steel,one. mm
  • Insulation thickness:100mm

 four.4 Heating System

  • The heating method is a indirect steam sort.
  • The indirect technique will be via stainless-steel or copper tubing sort warmth exchanger placed on the rear side of the autoclave between fan and goods. The circulation have to shift from material to admirer, then transfer entrance doorway employing vessel facet to content
  • Heating Exchanger material :304 Stainless-metal with aluminum fin or copper tubing aluminum fin
  • Heating Exchanger sort: Multi-row finned tubing

four.five Air Recirculating Method
