Product Description 1. Applications of SINOMAC Vulcanization AutoclaveRubber vulcanization is a chemical process at a given pressure, temperature and time for converting natural rubber into more durable materials by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains. Vulcanized materials are less sticky and have superior mechanical properties. And vulcanization autoclave is used widely for this chemical process. The main products are galoshes, rubber tubes, cable, rubber roller, rubber ball, etc.In this field, SINOMAC has been the leader, as we have accumulated full vulcanization experience and technology for many years.2. Basic Design Data 2.1 Model and SizeAutoclave model: SN-LHGR2050DEffective diameter: 2000mmEffective length: 5000mm Definition: * Effective diameter is the inner diameter of the autoclave. * Effective length is to point to do the actual length of the shell.2.2 Production CapacityWorking circle of autoclave: can be set according to the working processMax size of pulley: ?1700X5000mm2.3 Electric Power Operating voltage: 415V (AC)±5%, 3 phase, 50 Hz Control power: 220VAC/50Hz/24VDC2.4 Water, Air and Steam SupplyCooling water consumption: ~2m3/h Cooling water pressure: min.3 bar ~ max. 6 barControl air of control equipment: 5 ~ 7barSteam capacity: 2t/h2.5 Environmental Conditions Max. air temperature: +50oCMin air temperature: -5oCRelative Humidity: <80%Altitude: <2000m3. General Feature and Working Process3.1. General FeatureAutoclaves with direct steam: heating and pressurization are carried out with steam. This heating system is particularly effective and indicated for products of large sizes and weight. The temperature uniformity which normally varies between +/- 2°C,the exchange capacity, occurring with condensation on colder surfaces, coupled with tested installations, allow to obtain excellent results.3.2 Working Process3.2.1 Standard curing recipe Item Temp. setpointSoak TimeTemp. step durationSegment1T1t 1-2t 1Segment2T2t 3-4t 2Segment3T3t 5-6t 33.2.2 A short curing recipe example4. Equipment Technical Details4.1 Pressure VesselSINOMAC Pressure vessel with quick-opening door, can be certified to:CHINESE STANDARD, GB150-2011AMERICAN STANDARD ASME SEC VIII DIV.1 with ASME CertificateEUROPEAN STANDARD PED 97/23/EC with CE certificate.4.2 Door SystemThe closing system of the autoclave is the indented kind assisted with a hydraulic system, in order to quickly and secured make a totally hermetic closing. The whole system consists of three parts: a pair of gear flange, driven devices and seal ring.Hydraulically operated door opening and closing. It is controlled by PLC system. The seal ring is made of silicon rubber.Safety pressure sensors have to prevent door opening in case of pressure (allowed less than 0.1 bars).4.3 Thermal Insulation SystemInternal Insulation and External InsulationWe use ceramic fiber as the insulation material. The heat transfer coefficient is very low to make the heat loss to a minimum. The covering board of ceramic fiber is stainless steel. It is corrosion resistant and looks nice. Internal insulation design can get a low energy consumption, while external insulation design gets a high one, but a better temperature uniformity.Insulation:External insulation layerInsulation material:Ceramic fiber External sheet metal: stainless steel,1.0 mmInsulation thickness:50mm4.4 Internal CoatingPurpose: Anti-corrosionSpraying process: Aluminum coatingThickness:0.15-0.2mm4.5 Hot Air Circulating SystemWe use modified centrifugal impellers, which can generate large air flow and high air pressure. And we adopt a dynamic and mechanical sealing design. The dynamic and static ring sealing material is silicon carbide-graphite.The design of air duct structure is a U type with flow guiding device, which can ensure the adequacy of hot air circulation. The forced convection rate inside the autoclave can reach more than 90%. By this design, the system can obtain a steady and uniform temperature rising rate.4.5 Internal Rails and ComponentsRails: 100x75X8mm Angle, stainless steel Steam spray pipe:stainless steel 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 equipped a lot of small holes. Steam through these holes evenly spread into the autoclave, heating and pressure for product. Holes installation direction can guarantee steam spraying along the wall of autoclave, rather than directly sprayed onto the product, guarantee the quality of products..4.8 Drainage It plays a role of exhausting condensed water and consists of drainage pipeline connector, steam trap, blow-down valve. It connects with the flange in the bottom of autoclave. The condensed water is continuously exhausted through steam trap after sedimentation in the connector. Blow-down can exhaust condensed water and sludge non-scheduled.4.9 Pressure Components Inlet and exhaust valve, proportionally controlled, Electric control valve.Manual exhaust valve, 3-piece ball valve.Pressure transducer: 1 Accuracy: +/- 50mbar Pressure gauge:1 4.10 Control SystemControl System is developed based on the research and development toward rubber vulcanization processing industry, including the PLC central controlling part, touch screen (HIM) operation system and network, it is a user friendly, state of the art, programmable digital system.Password protected entry access, operator can log into the system by accessing the security login form with a name and password.It is automatic controlling, recording and graph the temperatures and pressure of the autoclave, audible alarms for high or low temperatures or pressure.Manual operation screen allows operator take manual control temperature, pressure, and valves as allowed.It can insert or save the product working recipe, display the pressure and temperature curve anytime; and its paperless record function can realize record, save and check of technique curve and process parameters.It has over-temperature and overpressure alarm and various safety protection functions.Customer can operate register, login and typing in product information, and realize intranet or remote control. Communication to a Personal Computer allowed (Teamviewer ), with built in software to program, record and graph of process in real time.Internet connection via Team-Viewer (VPN) with our Company.4.11 Safety System 4.11.1 Mechanical safety interlock I Safety limit handle is interlocked with the lid. Workers have to turn the handle to unlock the safety device then the lid can be opened.4.11.2 Electrical safety interlock II The safety device works with safety limit handle and connects with our ECC. When workers operate the reducer and safety limit handle, while there is pressure in the autoclave, the ECC will give a sound-light alarm.4.11.3 Safety valvesThere is one safety valves on the top of autoclave. We have set a pressure limit in the valves. When the pressure exceed the limit, the valves will work automatically to release the air down to a reasonable pressure range.5.
