Background of Cooperation
Shanshan Technology, a leading company in the new energy lithium battery industry, faces stringent challenges in the production of positive and negative electrode materials. Existing sealing solutions are insufficient to meet production needs, necessitating professional sealing technology support. Based on our company’s technical accumulation and industry reputation in the field of mechanical seals, Shanshan Technology has partnered with us to jointly overcome the sealing challenges of positive and negative electrode production equipment.
Core Pain Points of Customers
(1) Pain Points of Negative Electrode Production Equipment
The high-temperature coated reactor used in negative electrode production can reach a maximum operating temperature of 800℃, and the axial extension of the horizontal reactor is as high as 40mm. Under the combined effects of high temperature and large axial extension, the spindle swing increases significantly, leading to premature failure of traditional mechanical seals. This not only affects production continuity but also significantly increases equipment maintenance costs and downtime losses.
(2) Pain Points of Positive Electrode Production Equipment
The positive electrode reactor is used for raw material synthesis, and the operating conditions involve highly toxic and corrosive media. Traditional sealing solutions cannot effectively prevent the leakage of hazardous media, posing a serious threat to the personal safety of operators and potentially causing environmental pollution, thus failing to meet relevant environmental protection and safe production standards.
Customized Solutions
Addressing the different operating conditions of Shanshan Technology’s positive and negative electrode production equipment, our company has assembled a dedicated technical team. After multiple rounds of technical discussions and experimental verification, we have launched two customized sealing solutions:
(1) Negative Electrode Equipment Sealing Solution
Our company has independently developed and launched a floating ring + labyrinth combination sealing structure protected by multiple patents. This structure fully considers the high-temperature characteristics of the high-temperature coated reactor and the operating requirements of 40mm axial extension. Through the synergistic effect of the floating ring and labyrinth, it effectively absorbs the spindle oscillation and offsets the sealing compensation pressure caused by axial extension, fundamentally solving the problem of early mechanical seal failure caused by high temperature and large axial extension, ensuring stable operation of the equipment under extreme conditions.
(2) Positive Electrode Equipment Sealing Solution
Addressing the highly toxic and corrosive operating conditions of the positive electrode reactor, our company has customized and developed a dry-running mechanical seal. The sealing materials selected are PTFE (polytetrafluoroethylene) and SSiC (silicon carbide). PTFE possesses excellent corrosion resistance, resisting the erosion of various highly toxic and corrosive media, while SSiC features high strength and high wear resistance, ensuring long-term stable sealing performance of the sealing end face. This solution achieves effective sealing of highly hazardous media, minimizing the risk of media leakage, reducing environmental harm to the greatest extent, and ensuring safety on the production site.
Cooperation Results
1.Significantly Improved Stability: After adopting the floating ring + labyrinth combination seal in the negative electrode equipment, the problem of early mechanical seal failure was completely solved, significantly extending the continuous operation time of the equipment and reducing the maintenance frequency by more than 60%. The positive electrode dry-running mechanical seal achieved zero-leakage sealing for highly toxic and corrosive media, meeting environmental protection and safe production requirements.
2.Effective Cost Control: The extended service life of the seals reduces the frequency of seal replacement and maintenance labor costs, while avoiding production downtime losses due to seal failure, thus reducing the overall production costs for Shanshan Technology.
3.High Technical Recognition: The customized solution precisely matches the unique operating conditions of positive and negative electrode production, showcasing our company’s technical strength in the field of mechanical seals. This earned high recognition from Shanshan Technology, laying a solid foundation for further cooperation between the two parties.
This collaboration with Shanshan Technology represents a successful example of our company’s deep integration of sealing technology with the specific operating conditions of the new energy lithium battery industry. In the future, our company will continue to focus on industry pain points, further develop customized sealing solutions, and provide reliable and efficient sealing technology support to more new energy companies.
