Vulcanization Process Descriptions:
  1. What is the whole process of the vulcanized products of the electrothermal vulcanizing machine? Taking an electric heating vulcanizing machine with two template changing devices separately as an example, this type of vulcanizing machine can be operated from both sides, or can be automatically fed into the mold and out of the mold.
  2. The vulcanizer operator puts the compound into the open lower mold and covers the mold under the action of the hydraulic cylinder. After the mold cover, it will automatically move to the vulcanization chamber of the vulcanizer and begin the vulcanization process.
  3. After the vulcanization of the rubber compound is finished, the vulcanizer automatically opens, and the plunger begins to descend under the action of its own gravity and the hydraulic cylinder. When it is lowered to a predetermined position, the thrust lever of the model changing mechanism is touched. The mold containing the rubber is automatically pulled out from the heating plate of the vulcanizing agent, which is convenient for the operator to discharge and reload.
  4. In order to increase the lowering speed of the lower-cylinder flat vulcanizer platform, a return cylinder may be provided, or the cylinder may be designed as a double-acting cylinder to return the platform and the plunger under hydraulic pressure.


Brief Introduction of Vulcanizing :
  1. Vulcanization is the process of chemical crosslinking of rubber macromolecules under certain conditions. Among them, certain conditions refer to time, temperature and pressure, which are the three elements of vulcanization. Tire vulcanization is to put the formed green tire into the model, and through the three related vulcanization factors of time, temperature and pressure, the performance of each combination is optimized to obtain the physical and mechanical properties required by the formulator. Vulcanization of the tire includes post-vulcanization of the tire in the mold after vulcanization and vulcanization in the mold.
  2. The rubber vulcanization reaction process: including the induction phase, the crosslinking reaction phase, and the network structure stroke phase. Induction phase promoter polysulfide - rubber - a polysulfide compound containing a rubber molecular chain - decomposes free radicals or ions. Rubber cross-linking reaction stage - cross-linked cross-linking rearrangement cracking, main chain modification. The formation stage of the network - vulcanized rubber. In the early stage of the formation phase of the network, the cross-linking reaction tends to be completed, and the cross-linking bonds are rearranged and cracked. At the later stage, the cross-linking reaction has basically stopped, and the main reason is the rearrangement of cross-linking bonds. And cleavage reaction.
  3. The scorch phase: corresponds to the induction phase in the sulfurization reaction. Refers to the delay time before the start of thermal vulcanization, that is, the time the compound flows. Divided into operating scorch time and remaining scorch time.
