6) Insulator Silicone Rubber High Temperature Vulcanization Process

Описание: After the semi-finished product without vulcanization is loaded into the model, the model is placed in the gap between the two hot plates (for no modeled articles such as tape and rubber sheets placed directly between the hot plates). The hydraulic medium (oil or water) is then passed into the hydraulic cylinder, and the plunger pushes the movable platform and the hot plate upward or downward, and pushes the movable plate to press the mold or the product. While performing the above movement, the heating medium is passed into the heating plate, so that the model (or product) obtains the pressure and temperature required for the vulcanization process, and after a period of time (vulcanization cycle), the product is vulcanized, and then the inside of the hydraulic cylinder is The hydraulic medium is removed, and the product can be taken out because the plunger is lowered by its own weight (or the hydraulic pressure of the double-acting cylinder).

When the flat vulcanizing machine is working, the hot plate heats up the rubber and cross links the rubber molecules, and the structure changes from a linear structure to a mesh-shaped body structure, which is a product that can obtain certain physical and mechanical properties, but the rubber compound After being heated, it begins to soften, and at the same time, the moisture and volatile substances in the rubber compound are vaporized. At this time, the hydraulic cylinder is used to give sufficient pressure to fill the mold, and the formation of bubbles is restricted, so that the structure of the product is dense. To. If it is a tape laminate, the glue and the cloth can be firmly adhered. In addition, sufficient pressure is applied to prevent the phenomenon of overflow of the mold, lack of glue, and pores of the sponge.
