Technology empowers high-temperature transportation scenarios | Hebei Boao Rubber Technology's new high-temperature conveyor belt iteration strengthens the safety defense line for high-temperature industrial transportatio

Recently, Hebei Boao Rubber Technology Co., Ltd., which has been deeply engaged in the research and manufacturing of rubber conveying products for over 20 years, has completed the process upgrade and mass production implementation of a new generation of modified high-temperature-resistant rubber conveying belts. Relying on its independently developed special heat-resistant rubber compound formula and integrated constant-temperature vulcanization process, the company has optimized and upgraded the entire series of high-temperature-resistant conveying belts, effectively solving the industry pain points such as aging, delamination, cracking, and short service life of high-temperature material conveying belts in industries like metallurgy, cement, thermal power, and chemical engineering. With high-quality conveying products, it helps domestic industrial production lines in high-temperature working conditions reduce costs, increase efficiency, and ensure safe and stable production.

In response to the current pain points of high-temperature industrial conveying conditions, the upgraded high-temperature-resistant conveying belts this time have achieved triple breakthroughs in formula, structure, and process. At the raw material end, the company independently formulates a special heat-resistant composite rubber formula, combines with high-modulus polyester reinforcing skeleton materials, optimizes the physical and chemical properties of the covering layer, and after a 70℃×168h aging test, the tensile strength retention rate of the product is ≥80%, the wear volume is ≤200mm³, and the heat resistance and anti-aging performance far exceed the industry standards of the national standard; at the process end, it is equipped with a fully automatic mixing system and a wide-width integrated constant-temperature vulcanization production line, discarding the traditional segmented vulcanization process, significantly improving the bonding force between the belt body gel and the skeleton layer, and completely avoiding delamination and gelation faults in high-temperature environments.

In terms of performance, this high-temperature-resistant conveyor belt can be used for continuous material transportation at temperatures up to 200℃. It is suitable for transporting materials such as clinker, slag, high-temperature sand and gravel, slag, and chemical hot materials. Compared to ordinary heat-resistant conveyor belts on the market, its service life under normal 150℃ conditions is increased by more than 30%. It has significantly enhanced resistance to cracking, deformation, and thermal corrosion. At the same time, the enterprise can customize EP layered, steel wire rope core, and ring-shaped jointless multi-structure high-temperature-resistant conveyor belts according to needs, which are suitable for long-distance, large-capacity, high-strength, and inclined-type various conveying equipment, balancing both general applicability and customized compatibility.

Compared with traditional high-temperature-resistant conveying products, the new model of Boao's high-temperature-resistant conveyor belt has three core advantages: Firstly, it has strong heat resistance stability. The exclusive heat insulation layer prevents the transmission of high temperatures and avoids the failure of the frame layer due to heat, making it suitable for all-weather continuous high-temperature operations. Secondly, it has high bonding strength. By optimizing the vulcanization parameters, the bonding degree between the gel layer and the fabric layer, and the steel wire rope core has been upgraded, ensuring that the heavy-load and high-temperature operation does not crack or separate. Thirdly, it has low operation and maintenance costs. With the dual support of wear resistance and heat resistance, the replacement frequency is reduced, significantly reducing the equipment downtime, material procurement, and labor operation costs of enterprises. After years of deepening in the rubber conveying field, Hebei Boao Rubber Technology has always focused on technological breakthroughs in conveying products under extreme conditions. Besides high-temperature-resistant conveyor belts, it is also concurrently developing flame-retardant conveyor belts, patterned conveyor belts, high-bonding force nylon conveyor belts, and steel wire rope core conveyor belts of all categories, forming a full-range conveying product matrix for all working conditions. In the future, the enterprise will continue to increase investment in research and development of special rubber materials with heat resistance, wear resistance, and flame retardancy, iterate high-end functional conveyor belt products, and focus on the North China region while radiating to the entire country. With standardized quality, customized services, and full-cycle after-sales support, it will help the industrial conveying industry improve quality and upgrade, and create a domestic benchmark manufacturing brand for high-temperature-resistant conveyor belts.
