1. Applications of CZPT Vulcanization Autoclave
Rubber vulcanization is a chemical process at a provided pressure, temperature and time for converting natural rubber into far more durable resources by the addition of sulfur. These additives modify the polymer by forming cross-links (bridges) amongst specific polymer chains. Vulcanized materials are significantly less sticky and have superior mechanical qualities. And vulcanization autoclave is used broadly for this chemical approach. The primary goods are galoshes, rubber tubes, cable, rubber roller, rubber ball, and many others.In this area, CZPT has been the chief, as we have gathered total vulcanization encounter and technological innovation for numerous years.

three. CZPT Function and Working Process
three.one. CZPT Feature
Autoclaves with immediate steam: heating and pressurization are carried out with steam. This heating method is especially effective and indicated for goods of large sizes and bodyweight. The temperature uniformity which normally varies in between ±2°C,the exchange ability, taking place with condensation on colder surfaces, coupled with tested installations, permit to obtain excellent outcomes.

4.3 Thermal Insulation Technique
Internal Insulation and Exterior Insulation
We use ceramic fiber as the insulation substance. The heat transfer coefficient is really minimal to make the warmth reduction to a minimum. The covering board of ceramic fiber is stainless steel. It is corrosion resistant and seems great. Inside insulation layout can get a low strength intake, although exterior insulation style will get a high one, but a much better temperature uniformity.

- Exterior sheet steel: stainless metal,1. mm
- Insulation thickness:100mm
four.4 Heating System
- The heating program is a oblique steam sort.
- The oblique system will be through stainless-steel or copper tubing variety warmth exchanger placed on the rear facet of the autoclave amongst enthusiast and goods. The circulation have to transfer from substance to enthusiast, then shift entrance door making use of vessel aspect to content
