1. Applications of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a presented pressure, temperature and time for converting all-natural rubber into more tough materials by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) in between personal polymer chains. Vulcanized resources are less sticky and have exceptional mechanical homes. And vulcanization autoclave is utilized widely for this chemical approach. The major goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, and so forth.In this field, CZPT has been the leader, as we have accrued total vulcanization experience and technologies for many many years.

3. CZPT Function and Working Method

three.1. CZPT Characteristic
Autoclaves with direct steam: heating and pressurization are carried out with steam. This heating program is specifically effective and indicated for items of large sizes and excess weight. The temperature uniformity which normally differs among +/- 2°C,the trade capacity, happening with condensation on colder surfaces, coupled with examined installations, permit to obtain excellent results.

4. Tools CZPT Specifics

four.1 Pressure Vessel

CZPT Force vessel with fast-opening doorway, can be accredited to:

  • CHINESE STHangCZPTRD, GB150-2011
  • EUROPEAN STHangCZPTRD PED 97/23/EC with CE certificate.

four.2 CZPT System

  • The closing method of the autoclave is the indented variety assisted with a hydraulic technique, in get to swiftly and secured make a totally hermetic closing.
  • The complete method is composed of a few parts: a pair of equipment flange, driven products and seal ring.
  • CZPTally operated door opening and closing. It is managed by PLC technique.
  • The seal ring is manufactured of silicon rubber.
  • Basic safety force sensors have to stop doorway opening in case of force (permitted much less than .1 bars).

4.3 Thermal Insulation Method

Interior Insulation and External Insulation
We use ceramic fiber as the insulation substance. The warmth transfer coefficient is very lower to make the warmth decline to a minimum. The covering board of ceramic fiber is stainless steel. It is corrosion resistant and seems to be good. Inside insulation layout can get a minimal vitality use, whilst exterior insulation design and style gets a large one particular, but a far better temperature uniformity.

  • Insulation:External insulation layer
  • Insulation content:Ceramic fiber 
  • Exterior sheet metallic: stainless metal,1. mm
  • Insulation thickness:50mm

4.4 Internal Coating

  • Function: Anti-corrosion
  • Spraying procedure: Aluminum coating
  • Thickness:.fifteen-.2mm

4.5 Hot Air Circulating Method

We use modified centrifugal impellers, which can produce huge air movement and large air force. And we undertake a dynamic and mechanical sealing design. The dynamic and static ring sealing substance is silicon carbide-graphite.
The style of air duct framework is a U type with circulation guiding unit, which can make certain the adequacy of very hot air circulation. The compelled convection charge inside the autoclave can reach far more than 90%. By this layout, the system can acquire a constant and uniform temperature rising charge.

four.5 Internal Rails and Factors

  • Rails: 100x75X8mm Angle, stainless metal
  • Steam spray pipe:stainless metal
  • Pipe joints on autoclave: stainless steel 

four.7 Direct Steam Heating and Pressurization

There are two steam distribution pipes at the two sides of the autoclave, which respectively equipped a good deal of little holes. Steam via these holes evenly distribute into the autoclave, heating and strain for merchandise. Holes set up course can ensure steam spraying together the wall of autoclave, relatively than right sprayed on to the merchandise, assure the quality of merchandise..

4.eight Drainage 

It plays a part of exhausting condensed water and is composed of drainage pipeline connector, steam entice, blow-down valve. It connects with the flange in the base of autoclave. The condensed h2o is repeatedly exhausted by way of steam trap after sedimentation in the connector. Blow-down can exhaust condensed drinking water and sludge non-scheduled.
