Rubber vulcanizing apparatusIt is an experimental device used to test the changes in physical properties of rubber and its products during the vulcanization process. It simulates the vulcanization conditions in actual production, precisely controls parameters such as temperature, pressure, and time, and continuously measures the physical property changes of rubber materials during the vulcanization process, such as shear modulus, torque, etc., in order to evaluate the vulcanization state of rubber materials and provide important basis for quality control, formula optimization, and production process improvement of rubber products.
According to the measurement principle, vulcanizers can be divided into two types: one is to apply a certain amplitude of force to the rubber material and measure the corresponding deformation; Another type applies a certain amplitude of shear deformation to the rubber material and measures the corresponding shear force. Most domestic equipment uses a rotorless vulcanizing instrument to measure the torque changes during rubber vulcanization by measuring the shear strain inside a closed mold cavity.
The application fields of vulcanizing instruments in rubber product production mainly include the following aspects:
Manufacturers use vulcanizing instruments to test the reproducibility and stability of products, ensuring that the vulcanization characteristics of each batch of rubber meet the product requirements, thereby effectively controlling product quality.
In the production of rubber seals and other products, vulcanizing instruments are used for incoming inspection of raw materials to avoid vulcanization performance defects from the source and ensure that the quality of raw materials meets standards.
The vulcanizer is a key testing instrument for developing new products and researching rubber compound formulas. It can analyze performance indicators such as scorch time, positive vulcanization time, and vulcanization rate during the rubber vulcanization process, providing data support for formula optimization.
Determination of process parameters
By simulating the temperature, pressure, and time parameters during the vulcanization process, the vulcanizing instrument can scientifically determine the three key elements of vulcanization (time, temperature, and pressure), providing a basis for process settings.
