What is the working principle of a vulcanized rubber machine?
Vulcanized rubber machine is a specialized equipment for vulcanizing rubber products.Its working principle is to form cross-linked structures between rubber molecules through heating and pressure,allowing rubber to achieve higher strength and heat resistance.The following will provide a detailed introduction to the working principle of the vulcanized rubber machine.
The vulcanized rubber machine mainly consists of a heating system,a pressure system,and a control system.Firstly,place the rubber product into the working chamber of the vulcanizing rubber machine,and then start the heating system to heat the working chamber to reach the required vulcanization temperature.Heating systems usually use electric heating or steam heating to adjust according to different vulcanization needs.
When the working chamber reaches the vulcanization temperature,the pressure system is activated,and pressure is applied through hydraulic or pneumatic cylinders to evenly compress the rubber products,so as to form more cross-linked structures between rubber molecules during the vulcanization process.In this process,the shape and size of rubber products will be limited by the mold,so choosing the appropriate mold is very important.

When rubber products are subjected to vulcanization temperature and pressure,the vulcanization reaction begins.The sulfur in rubber undergoes chemical reactions with rubber molecules through thermal energy or chemical reactions,forming cross-linked structures.The specific reaction mechanism mainly involves the reaction between sulfur atoms and allyl hydrogen atoms in the rubber chain,forming a cross-linked structure.
The control system in the vulcanizing rubber machine plays a role in controlling parameters such as temperature,time,and pressure.By controlling the system,the temperature and time of vulcanization can be adjusted to ensure that the rubber can undergo sufficient vulcanization reaction.The control system can also monitor and record temperature and pressure changes during the vulcanization process for subsequent quality control and production management.
During the vulcanization process,cross-linked structures are formed between rubber molecules,resulting in higher strength,wear resistance,and heat resistance of rubber products,thereby improving the physical properties and durability of rubber.At the same time,the vulcanization process can also improve the chemical stability and anti-aging performance of rubber,so that rubber is not easy to deteriorate and age in the use process.
In summary,the working principle of a vulcanizing rubber machine is to improve the physical properties and durability of rubber by forming cross-linked structures between rubber molecules through heating and pressure.In the process of manufacturing rubber products,vulcanized rubber machines play a crucial role.Through reasonable operation and control,high-quality vulcanized rubber products can be produced.
