2500X5000mm PED Standard Industrial Vulcanizating Autoclave for Curing Rubber Rollers

2500X5000mm PED Standard Industrial Vulcanizating Autoclave for Curing Rubber Rollers

1. Programs of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a presented stress, temperature and time for changing normal rubber into much more tough components by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst personal polymer chains. Vulcanized supplies are less sticky and have outstanding mechanical properties. And vulcanization autoclave is utilized broadly for this chemical process. The major goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this subject, CZPT has been the chief, as we have amassed full vulcanization encounter and engineering for several a long time.

3. CZPT Characteristic and Operating Approach

three.one. CZPT Characteristic
Autoclaves with direct steam: heating and pressurization are carried out with steam. This heating technique is especially effective and indicated for items of huge sizes and fat. The temperature uniformity which normally may differ between ±2°C,the exchange potential, occurring with condensation on colder surfaces, coupled with tested installations, allow to obtain excellent outcomes.

four. Equipment CZPT Particulars

four.1 Pressure Vessel

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

  • CHINESE STHangCZPTRD, GB150-2011
  • AMERICAN STHangCZPTRD ASME SEC VIII DIV.one with ASME Certificate
  • EUROPEAN STHangCZPTRD PED ninety seven/23/EC with CE certification.

four.2 CZPT System

  • The closing technique of the autoclave is the indented kind assisted with a hydraulic program, in buy to rapidly and secured make a totally airtight closing.
  • The entire system consists of three areas: a pair of equipment flange, pushed units and seal ring.
  • CZPTally operated door opening and closing. It is managed by PLC technique.
  • The seal ring is produced of silicon rubber.
  • Protection force sensors have to prevent doorway opening in situation of strain (authorized significantly less than .1 bars).

4.3 Thermal Insulation Program
Inner Insulation and Exterior Insulation
We use ceramic fiber as the insulation substance. The warmth transfer coefficient is really lower to make the warmth reduction to a bare minimum. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and seems wonderful. Inner insulation design and style can get a minimal power intake, even though external insulation design and style gets a substantial a single, but a far better temperature uniformity.

  • Insulation:Internal insulation layer
  • Insulation substance:Ceramic fiber 
  • Exterior sheet metallic: stainless metal,one. mm
  • Insulation thickness:100mm

 four.4 Heating Program

  • The heating method is a oblique steam type.
  • The oblique technique will be via stainless-steel or copper tubing type heat exchanger put on the rear aspect of the autoclave amongst fan and items. The stream have to transfer from content to enthusiast, then go front doorway employing vessel facet to content
  • Heating Exchanger material :304 Stainless-steel with aluminum fin or copper tubing aluminum fin
