Machine Maintenance Manual:
As a conveyor belt joint tool, the vulcanizing machine should be maintained and maintained in the same way as other tools during and after use to extend the service life. At present, the vulcanizing machine produced by Junan Machinery has a service life of 8 years as long as it is properly maintained.
The maintenance of the vulcanizer should be noted that the storage environment of the vulcanizer should be kept dry and well ventilated to avoid the wetness of the electrical circuit due to moisture; do not use the vulcanizer outdoors on rainy days to prevent the electric control box and the heating plate from entering the water; Wet, watery, when dismantling and handling the vulcanizing machine, the items should be raised on the ground, and the vulcanizer should not be in direct contact with water;
If the heating plate enters the water due to improper operation during use, first contact the manufacturer for repair. If emergency repair is required, open the cover on the hot plate, pour the water out first, then set the electric control box to manual operation, warm to 100 ° C, keep the temperature for half an hour, and dry the line. The belt is glued in the manual state. At the same time, the manufacturer should be contacted in time to make the overall replacement of the line.
When the vulcanizer does not need to be used for a long time, the heating plate should be heated every half month (temperature setting 100 ° C), and the temperature is maintained for about half an hour.
After each use, the water in the water pressure plate should be cleaned, especially in winter. If the water cannot be cleaned, the water pressure plate rubber will prematurely age and the service life of the water pressure plate will decrease.
The correct way to release water is after the vulcanization is completed and the vulcanizer is not removed before disassembly. If the water is released after the machine is disassembled, the water in the water pressure plate may not be completely discharged.
What are the main factors affecting the vulcanization process:
1. Vulcanization temperature: If the temperature is 10 °C higher, the vulcanization time of the vulcanizing press is shortened by about half. Since the rubber is a poor thermal conductor, the vulcanization process of the product differs due to the difference in temperature of each part. In order to ensure a relatively uniform degree of vulcanization, thick rubber products generally adopt a gradual heating, low temperature and long-term vulcanization.
2, vulcanization time: This is an important part of the vulcanization process. The time is too short, the degree of vulcanization is insufficient (also known as sulfur). The time is too long, the degree of vulcanization is too high (commonly known as sulfur). The vulcanizing machine only has a suitable degree of vulcanization ( Commonly known as vulcanization), to ensure the best overall performance.
3. Sulfur dosage: The larger the dosage, the faster the vulcanization rate, the higher the degree of vulcanization that can be achieved by the vulcanizing press. The solubility of sulfur in rubber is limited, and the excessive sulfur will be precipitated from the surface of the rubber compound. Sulfur". In order to reduce the phenomenon of sulfur spraying, it is required to add sulfur at the lowest possible temperature, or at least below the melting point of sulfur. According to the requirements of rubber products, the amount of sulfur in soft rubber is generally not more than 3 %, the amount in the semi-hard rubber is generally about 20%, and the amount in the hard rubber vulcanization condition can be as high as 40% or more.
