In industrial production, the quality of conveyor belt splicing is crucial to the overall stability, efficiency, and longevity of the conveyor system. As a professor of conveyor belt hot vulcanization, we understand the importance of selecting the right adhesive material to ensure splicing quality. This article explores the key factors to consider when choosing the right splicing materials for hot vulcanized joints.
1. Basic Characteristics of Hot Vulcanization Adhesives
Hot vulcanization adhesives are specialized rubber materials that, when heated, tightly bond with the belt material, creating a strong, flexible joint with excellent abrasion resistance, tear resistance, and durability. Temperature and timing during the vulcanization process are critical and must align with equipment specifications to ensure optimal joint quality and performance.
2. Choosing Adhesives Based on Belt Material
Different belt materials (such as PVC, PU, and rubber) have unique requirements for adhesives. For example, PVC belts require adhesives with high adhesion and corrosion resistance, while rubber belts prioritize abrasion resistance and elasticity. Understanding the characteristics of the conveyor belt material and selecting a compatible adhesive help achieve a strong bond and high-strength joint.
3. Impact of the Working Environment
The operating environment of the conveyor belt also plays an essential role in adhesive selection. For instance, a humid environment requires adhesives with strong water resistance, while high-temperature conditions call for heat-resistant adhesives. Additionally, the type of materials being transported should be considered—whether they include sharp objects or produce static electricity—as these factors can affect adhesive performance.
4. Adhesive Components in Hot Vulcanization
- Uncured Cover Rubber: Primarily made of natural and synthetic rubber, this rubber has excellent bonding properties and high tensile strength. Its flowability during vulcanization allows for even filling and adhesion in the joint area. Uncured Cover rubber is commonly used in steel cord, nylon, and polyester belts, frequently applied in coal mines, power plants, and steel mills.
- Uncured Skim Rubber(Tie Gum): This rubber is used on the outer layer of the joint, bonding seamlessly with the belt’s surface after vulcanization. It provides abrasion resistance, corrosion resistance, and anti-aging properties, ensuring the joint’s strength. This type of rubber is suitable for hot vulcanization joints of steel-cord and nylon conveyor belts.
- Hot Vulcanization Cement: With flame-resistant properties and exceptional adhesion, this cement penetrates the fabric layer of the belt, significantly increasing joint strength. It is ideal for joints in various conveyor belts, especially in high-load conditions.
- Cleaning Agent: Used to remove oil and impurities from the joint area, this non-flammable, non-explosive cleaner is suitable for aboveground and underground use, ensuring a clean bonding surface for the vulcanization process.
The Importance of Selecting the Right Adhesive
Choosing the appropriate hot splicing materials requires considering the splicing materials’ characteristics, the belt material, the working environment, brand reliability, and supplier quality. In practical applications, testing and evaluation are necessary to ensure that the rubber materials meet specific requirements, ultimately enhancing joint quality and extending belt lifespan.
