Full Automatic Diameter 2000mm Rubber Vulcanizating Autoclave

one. Applications of CZPT Vulcanization Autoclave
Rubber vulcanization is a chemical process at a presented strain, temperature and time for changing normal rubber into more sturdy materials by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst individual polymer chains. Vulcanized supplies are much less sticky and have outstanding mechanical properties. And vulcanization autoclave is used broadly for this chemical process. The principal goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, and so forth.In this area, CZPT has been the leader, as we have accrued complete vulcanization experience and technology for a lot of many years.

3. CZPT Attribute and Functioning Process

3.one. CZPT Attribute
Autoclaves with direct steam: heating and pressurization are carried out with steam. This heating system is specifically effective and indicated for items of large sizes and bodyweight. The temperature uniformity which usually may differ among +/- 2°C,the trade potential, happening with condensation on colder surfaces, coupled with examined installations, allow to obtain excellent benefits.

    e. Review NDT personnel qualification
    f. Assessment NDT documentation
    g. Hydrostatic test

four.2 CZPT System

  • The closing system of the autoclave is the indented type assisted with a hydraulic program, in get to speedily and secured make a absolutely airtight closing.
  • The whole technique is composed of a few parts: a pair of equipment flange, driven products and seal ring.
  • CZPTally operated doorway opening and closing. It is controlled by PLC technique.
  • The seal ring is manufactured of silicon rubber.
  • Security strain sensors have to avert doorway opening in scenario of pressure (authorized significantly less than .1 bars).

4.3 Thermal Insulation Program
Inside Insulation and External Insulation
We use ceramic fiber as the insulation materials. The heat transfer coefficient is really lower to make the warmth reduction to a least. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and seems to be good. Interior insulation design and style can get a low vitality consumption, although external insulation design and style receives a large one particular, but a better temperature uniformity.

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

four.4 Internal Coating

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

four.5 Hot Air Circulating Technique
We use modified centrifugal impellers, which can generate large air stream and higher air strain. And we undertake a dynamic and mechanical sealing design and style. The dynamic and static ring sealing substance is silicon carbide-graphite.
The layout of air duct structure is a U type with circulation guiding system, which can guarantee the adequacy of very hot air circulation. The compelled convection fee within the autoclave can reach far more than 90%. By this design, the system can get a regular and uniform temperature increasing price.
