ASME Certified Electric Heating Rubber Rollers Vulcanization Autoclave

ASME Certified Electric Heating Rubber Rollers Vulcanization Autoclave

one. Applications of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a given pressure, temperature and time for changing normal rubber into more tough supplies by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst person polymer chains. Vulcanized supplies are less sticky and have excellent mechanical qualities. And vulcanization autoclave is used widely for this chemical approach. The major products are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this area, CZPT has been the leader, as we have gathered full vulcanization experience and technology for many many years.

4.2 CZPT System

  • The closing system of the autoclave is the indented kind assisted with a hydraulic technique, in buy to swiftly and secured make a totally airtight closing.
  • The total program consists of three elements: a pair of equipment flange, driven products and seal ring.
  • CZPTally operated doorway opening and closing. It is controlled by PLC method.
  • The seal ring is produced of silicon rubber.
  • Basic safety force sensors have to avoid door opening in scenario of stress (permitted less than .1 bars).

4.3 Thermal Insulation Method
Internal Insulation and Exterior Insulation
We use ceramic fiber as the insulation materials. The warmth transfer coefficient is extremely low to make the heat decline to a minimum. The masking board of ceramic fiber is stainless metal. It is corrosion resistant and looks good. Inside insulation design can get a low energy consumption, even though external insulation layout will get a large one, but a much better temperature uniformity.

  • Insulation:Internal insulation layer
  • Insulation substance:Ceramic fiber 
  • Exterior sheet metal: stainless metal,1. mm
