Working Principle, Types And Maintenance

In the rubber manufacturing industry, Vulcanizers play a vital role. As a professional equipment, vulcanizers use heat and pressure to make rubber and vulcanizing agents undergo cross-linking reactions, thereby improving the strength, elasticity and durability of rubber. This article will give you a detailed introduction to the working principle, types, and maintenance of vulcanizers.

Working principle of vulcanizer

The core working principle of vulcanizer is the vulcanization process, which is to cross-link the vulcanizer (such as sulfur) with the polymer chains in the rubber through thermal energy to form a three-dimensional network structure. This structure makes the rubber have excellent physical properties and chemical stability after vulcanization.

The vulcanization process is usually divided into two stages: heating and curing. In the heating stage, the vulcanizer heats the rubber and vulcanizer to a certain temperature through the heating plate, and this process is usually carried out between 150°C and 180°C. Heating causes the vulcanizer to react chemically with the rubber to form a cross-linked structure. In the curing stage, the rubber is maintained at high temperature and high pressure for a certain period of time to ensure that the cross-linking reaction is completely carried out, thereby improving the overall performance of the rubber.

Vulcanizers are mainly divided into the following types, each of which has its own unique application scenarios and advantages:

Compression Molding Press

Compression Molding Press is the most common Vulcanization Equipment, which completes the vulcanization process by pressing the rubber mold together through mechanical pressure. This type of vulcanizer is suitable for small batch production and laboratory testing, and can provide high mold adaptability and flexibility. It is usually used to produce rubber products with complex shapes such as automobile tires and seals.

Fully Automatic Curing Press

The fully automatic curing press adopts an advanced automation control system to realize the automatic feeding, curing and material removal process. It is suitable for large-scale production and has high production efficiency and consistency. The fully automatic curing press can improve the automation level of the production line, reduce manual intervention, and is suitable for mass production of high-precision rubber products.

Hydraulic Curing Press

The hydraulic curing press provides high pressure through the hydraulic system and is suitable for curing processes that require high pressure and high temperature conditions. It is often used to produce high-strength and high-wear-resistant rubber products such as engineering tires and industrial seals. The hydraulic curing press has excellent pressure control capabilities and can ensure uniform curing effects.

Continuous Curing Line

The continuous curing press is suitable for processes that require continuous production, such as the production of long strip products such as rubber belts and hoses. It delivers rubber products into the curing zone for curing through a continuous conveyor belt, which can achieve a high-efficiency production process. Continuous vulcanizers provide stable production speeds and uniform vulcanization effects, suitable for large-scale production needs.

In order to ensure the normal operation of the vulcanizer and extend the life of the equipment, regular maintenance and care are essential. The following are some key aspects of maintenance and care:

The heating plate, sealing ring, hydraulic system and other components of the vulcanizer may wear or age during long-term use. Regularly checking the status of these components and replacing them as needed can ensure the normal operation of the equipment and improve production efficiency.

Clean the mixing chamber and heating plate of the vulcanizer regularly to prevent the accumulation of rubber residues. Cleaning can prevent contaminants from affecting product quality and keep the equipment in good working condition. In addition, check and clean the cooling system to ensure that it works properly and prevent the equipment from overheating.

The pressure sensor, temperature sensor, etc. of the vulcanizer need to be calibrated regularly to ensure the accuracy of their measurements. By adjusting the parameters of the equipment to ensure that key parameters such as temperature, pressure and time meet production requirements, the consistency and quality of the product can be improved.

Ensure that the safety protection devices and emergency stop systems of the vulcanizer are working properly. Regularly check the electrical system, hydraulic system and pneumatic system to ensure that there are no leakage, leakage or other safety hazards. Operators need to receive professional training and master the correct operating procedures and emergency response methods.

Establish detailed maintenance records and equipment operation logs to record the equipment's repair history, fault conditions, and maintenance. These records help track the status of the equipment, predict potential problems, and develop more effective maintenance plans.
