1. Purposes of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a provided strain, temperature and time for changing normal rubber into more tough resources by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) in between person polymer chains. Vulcanized supplies are considerably less sticky and have exceptional mechanical qualities. And vulcanization autoclave is utilised broadly for this chemical process. The main products are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this area, CZPT has been the leader, as we have accrued entire vulcanization expertise and technological innovation for several years.

3. CZPT Feature and Functioning Approach CZPT Feature
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating technique is notably effective and indicated for items of big sizes and bodyweight. The temperature uniformity which normally differs in between ±2°C,the trade ability, occurring with condensation on colder surfaces, coupled with tested installations, allow to obtain excellent results.

four.1 Pressure Vessel

CZPT Force Vessel with fast-opening door, can be licensed to:

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

four.2 CZPT System

  • The closing technique of the autoclave is the indented kind assisted with a hydraulic technique, in buy to swiftly and secured make a entirely airtight closing.
  • The complete technique consists of a few components: a pair of equipment flange, pushed devices and seal ring.
  • CZPTally operated door opening and closing. It is controlled by PLC method.
  • The seal ring is manufactured of silicon rubber.
  • Protection pressure sensors have to avoid doorway opening in scenario of strain (allowed considerably less than .1 bars).

4.3 Thermal Insulation Method
Interior Insulation and External Insulation
We use ceramic fiber as the insulation material. The heat transfer coefficient is quite low to make the warmth decline to a least. The masking board of ceramic fiber is stainless steel. It is corrosion resistant and seems nice. Inner insulation design and style can get a reduced power consumption, even though external insulation design receives a substantial one, but a much better temperature uniformity.

  • Insulation:Internal insulation layer
  • Insulation content:Ceramic fiber 
  • External sheet metal: stainless steel,1. mm
  • Insulation thickness:100mm

 4.4 Heating System

  • The heating system is a indirect steam kind.
  • The oblique technique will be by means of stainless-steel or copper tubing sort warmth exchanger placed on the rear side of the autoclave amongst enthusiast and merchandise. The movement have to go from materials to fan, then transfer entrance door utilizing vessel side to content
  • Heating Exchanger material :304 Stainless-steel with aluminum fin or copper tubing aluminum fin
  • Heating Exchanger type: Multi-row finned tubing

4.5 Air Recirculating Method
