2000X5000mm Direct Steam Heating PED Approved Industrial Rubber Vulcanizating Autoclave

2000X5000mm Direct Steam Heating PED Approved Industrial Rubber Vulcanizating Autoclave

1. Programs of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a given force, temperature and time for converting all-natural rubber into far more sturdy resources by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains. Vulcanized supplies are significantly less sticky and have outstanding mechanical properties. And vulcanization autoclave is utilised widely for this chemical method. The main merchandise are galoshes, rubber tubes, cable, rubber roller, rubber ball, and so forth.In this subject, CZPT has been the leader, as we have amassed entire vulcanization experience and engineering for several a long time.

3. CZPT Characteristic and Functioning Method

three.one. CZPT Characteristic
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating technique is specifically effective and indicated for merchandise of big sizes and excess weight. The temperature uniformity which normally varies among +/- 2°C,the trade capacity, happening with condensation on colder surfaces, coupled with examined installations, enable to obtain excellent results.

four. Equipment CZPT Information

four.1 Pressure Vessel

CZPT Pressure vessel with swift-opening door, can be licensed 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 kind assisted with a hydraulic method, in order to speedily and secured make a absolutely airtight closing.
  • The total system is composed of three elements: a pair of equipment flange, driven products and seal ring.
  • CZPTally operated door opening and closing. It is controlled by PLC program.
  • The seal ring is produced of silicon rubber.
  • Safety stress sensors have to stop door opening in situation of pressure (permitted considerably less than .1 bars).

four.3 Thermal Insulation System

Interior Insulation and Exterior Insulation
We use ceramic fiber as the insulation content. The warmth transfer coefficient is very minimal to make the warmth loss to a minimum. The masking board of ceramic fiber is stainless steel. It is corrosion resistant and seems nice. Inside insulation design and style can get a reduced vitality usage, although exterior insulation style gets a higher a single, but a much better temperature uniformity.

  • Insulation:External insulation layer
  • Insulation material:Ceramic fiber 
  • External sheet metallic: stainless steel,one. mm
  • Insulation thickness:50mm

4.4 Internal Coating

  • Goal: Anti-corrosion
  • Spraying procedure: Aluminum coating
  • Thickness:.15-.2mm

4.5 Hot Air Circulating Method

We use modified centrifugal impellers, which can make big air circulation and large air strain. And we adopt a dynamic and mechanical sealing style. The dynamic and static ring sealing materials is silicon carbide-graphite.
The style of air duct construction is a U type with movement guiding gadget, which can guarantee the adequacy of sizzling air circulation. The pressured convection rate within the autoclave can achieve a lot more than ninety%. By this design and style, the program can get a continual and uniform temperature rising charge.
