Direct Steam Heating Rubber Vulcanization Autoclave with Ce Certificate

1. Purposes of CZPT Vulcanization Autoclave

Rubber vulcanization is a chemical process at a provided force, temperature and time for changing normal rubber into more durable supplies by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst personal polymer chains. Vulcanized resources are less sticky and have excellent mechanical homes. And vulcanization autoclave is used broadly for this chemical procedure. The principal products are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this discipline, CZPT has been the chief, as we have accrued total vulcanization knowledge and technology for a lot of years.

3. CZPT Feature and Operating Process

3.1. CZPT Feature
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating system is notably effective and indicated for merchandise of huge sizes and weight. The temperature uniformity which normally may differ in between +/- 2°C,the exchange potential, transpiring with condensation on colder surfaces, coupled with analyzed installations, permit to obtain excellent outcomes.

four. Gear CZPT Specifics

four.1 Pressure Vessel

CZPT Stress vessel with fast-opening doorway, can be qualified to:

  • CHINESE STHangCZPTRD, GB150-2011
  • EUROPEAN STHangCZPTRD PED 97/23/EC with CE certification.

4.2 CZPT System

  • The closing system of the autoclave is the indented variety assisted with a hydraulic method, in get to swiftly and secured make a completely airtight closing.
  • The entire method is composed of a few parts: a pair of gear flange, pushed units and seal ring.
  • CZPTally operated doorway opening and closing. It is controlled by PLC system.
  • The seal ring is manufactured of silicon rubber.
  • Safety pressure sensors have to stop door opening in situation of strain (allowed much less than .1 bars).

4.3 Thermal Insulation Program

Interior Insulation and Exterior Insulation
We use ceramic fiber as the insulation content. The warmth transfer coefficient is extremely lower to make the heat decline to a minimum. The covering board of ceramic fiber is stainless metal. It is corrosion resistant and seems great. Interior insulation design and style can get a lower power use, while exterior insulation design and style receives a large one particular, but a far better temperature uniformity.

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

4.4 Internal Coating

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

4.5 Hot Air Circulating Method

We use modified centrifugal impellers, which can make massive air stream and high air pressure. And we undertake a dynamic and mechanical sealing design. The dynamic and static ring sealing materials is silicon carbide-graphite.
The design and style of air duct framework is a U type with flow guiding system, which can make certain the adequacy of scorching air circulation. The pressured convection charge inside the autoclave can achieve a lot more than ninety%. By this layout, the system can receive a constant and uniform temperature increasing fee.

four.5 Internal Rails and Parts

  • Rails: 100x75X8mm Angle, stainless metal
  • Steam spray pipe:stainless metal
  • Pipe joints on autoclave: stainless steel 

4.7 Direct Steam Heating and Pressurization

There are two steam distribution pipes at the two sides of the autoclave, which respectively geared up a lot of tiny holes. Steam by way of these holes evenly unfold into the autoclave, heating and strain for solution. Holes set up direction can guarantee steam spraying along the wall of autoclave, instead than right sprayed onto the solution, guarantee the quality of merchandise..

4.eight Drainage 

It performs a position of exhausting condensed h2o and is made up of drainage pipeline connector, steam entice, blow-down valve. It connects with the flange in the bottom of autoclave. The condensed water is continuously fatigued by means of steam entice soon after sedimentation in the connector. Blow-down can exhaust condensed drinking water and sludge non-scheduled.
