How much do you know about the vulcanization process?
Vulcanization is the last process in rubber processing, which can obtain finalized rubber products with practical value.
The function of vulcanization is to make the rubber molecules undergo a cross-linking reaction, transforming the original linear structure into a network structure, significantly improving the performance, and transforming the plastic body into an elastomer with practical use value.
In the production of rubber hoses, vulcanization is an important process to achieve a high bonding strength between the rubber and the reinforcing layer, making it a whole. It is also an important link to ensure product quality.
After vulcanization, the physical and mechanical properties of rubber such as strength, elasticity, tensile modulus, etc. will be significantly improved, plastic deformation will be reduced, and it will become an insoluble elastomer.
The processes before vulcanization, such as plasticizing, mixing, calendering, etc., are all preparations for vulcanization, and vulcanization is the core link to achieve performance.
Vulcanization is a key link in the production of rubber products, mainly for the following reasons
The vulcanization process gives rubber products the required physical and mechanical properties.
- Through vulcanization, a cross-linking reaction occurs between rubber molecules to form a three-dimensional network structure, which changes the rubber from a plastic state to a highly elastic state and obtains the required hardness, tensile strength, wear resistance and other properties.
- The control of vulcanization process parameters directly affects the comprehensive performance indicators of rubber products.
- Adjustment of vulcanization temperature, time, vulcanizing agent dosage and other parameters will have a decisive impact on the hardness, tensile strength, aging resistance and other properties of rubber products. Vulcanization is a key link in giving rubber products the required properties, which directly determines the quality of the product.
- Other processes such as mastication and mixing are all preparations for vulcanization, and vulcanization is the core of achieving performance.
- Improper vulcanization can lead to defects such as bubbles and poor bonding in rubber products.
- Bubbles will seriously affect key properties such as sealing and wear resistance of rubber products, so the control of the vulcanization process is particularly important.
- Vulcanization is an important process to make the rubber and the reinforcing layer form a whole
- For reinforced rubber products, vulcanization can improve the bonding strength between the rubber and the reinforcing layer to ensure overall performance.
In summary, the vulcanization process gives rubber products the required properties, controls product quality, and affects the integrity of rubber and reinforcement layers. It is the most critical link in the production of rubber products.
