Axle Head Wear

Due to the high hardness of the sulfur vulcanizing machine, it is prone to wear and tear due to vibration and impact during operation, as well as other complex forces, causing gaps in the components. Traditional repair methods, such as surfacing, thermal spraying, and electro-deposition, all have their drawbacks: surfacing can cause high temperatures on the surface of the parts, leading to deformation, cracks, and affecting dimensional accuracy and normal use; in severe cases, it can even cause fractures. Electro-deposition, although it has no thermal effects, is limited by the thickness of the coating layer, causing significant pollution and application restrictions. Western countries often use high polymer composite materials to address these issues. Their comprehensive properties and the ability to be machined at any time meet the requirements for the post-repair use and precision, while also reducing the impact and vibration that the equipment experiences during operation, thereby extending the service life. As the material has a "variable" relationship, when subjected to external force impacts, it deforms and absorbs the force, expanding and contracting with the expansion and contraction of the bearings or other components, maintaining a tight fit with the parts and reducing the likelihood of wear. For the wear of large sulfur vulcanizing machines, on-site repairs can also be performed using "molds" or "matching components" on the damaged equipment, avoiding the need for overall disassembly and ensuring the maximum fit of the components to meet the production and operation requirements of the equipment.

Substrate corrosion

The base plates of vulcanizing machines are typically made of ordinary carbon steel. The tires are vulcanized using high-temperature steam, during which the condensed water from this process seeps through to the surface of the base plate, causing localized corrosion and an uneven surface. Due to the severe corrosion on the base plate surface, it cannot be guaranteed to fit tightly with the insulating plate surface, and under high pressure, it is prone to damage the insulating plate. Traditional methods mainly involve re-welding and re-machining, or replacing new equipment. Currently, in-situ repair using high polymer composite materials can be adopted. Thanks to the material's excellent adhesion, corrosion resistance, and compressive strength, it can effectively address the issue of condensation water corrosion on the base plate, which leads to an uneven surface. This prevents the destruction of the insulating plate, providing a good guarantee for the normal operation and safe production of the user's equipment.
