The electrolyte used in lead-acid batteries is usually sulfuric acid solution, which is highly corrosive and easy to corrode metal parts and rubber materials. Long-term contact may cause material degradation or reduced sealing. In order to solve this problem, the HD-20 safety vent plug of Zhejiang Hongda Special Rubber Products Co., Ltd. fully considered corrosion resistance when designing, and adopted high-performance materials that can resist corrosion from lead-acid battery fluid.
The HD-20 safety vent plug of Zhejiang Hongda Special Rubber Products Co., Ltd. is made of high-quality acid-resistant rubber material, which has excellent corrosion resistance. It can maintain stable physical properties for a long time in the battery fluid corrosion environment, and is not easy to age, harden or crack. The elastic properties of the soft rubber material ensure that during the use of the battery, even if it is constantly in contact with the battery fluid, it will not affect the sealing effect of the vent plug, thereby ensuring the safety and reliability of the battery system.
In addition, the diameter of the vent plug cap is 28mm and the frame thickness is 8.5mm, so that the vent plug fits tightly with the battery cover, preventing battery fluid or other corrosive substances from penetrating into the vent plug, while ensuring that it can effectively seal the battery system for a long time.
In modern automotive and industrial applications, lead-acid batteries often encounter high-temperature working environments, especially in battery systems with frequent start-stop cycles. The battery generates a lot of heat during charging and discharging. The increase in temperature may cause an increase in internal pressure and even damage the external structure of the battery. To ensure safety, the HD-20 23mm High Lead-Acid Battery Safety Vent Plug uses high-temperature resistant materials and designs to maintain its performance and stability under high temperature conditions.
The high-temperature resistance of soft rubber materials is a significant feature of the HD-20 vent plug of Zhejiang Hongda Special Rubber Products Co., Ltd. The material can still maintain its flexibility and sealing when the temperature reaches a high level, and will not harden, crack or lose its sealing effect due to high temperature. The heat generated by the battery during charging and use will not affect the normal function of the vent plug, thereby ensuring that the battery system can still operate safely and stably under high temperature conditions.
The HD-20 23mm High Lead-Acid Battery Safety Vent Plug of Zhejiang Hongda Special Rubber Products Co., Ltd. has an overall height of 23 mm, compact size and sturdy structure. This compact design can effectively prevent the vent plug from overheating or mechanical damage. In addition, the soft rubber material also has a good thermal expansion coefficient match, which can adapt to the pressure changes caused by temperature fluctuations during battery operation, and is not prone to seal failure due to temperature changes.
The combination of high temperature resistance and corrosion resistance of the HD-20 safety vent plug is the key to its long-term stable operation in the battery system. Especially for battery systems under extreme working environments, such as start-stop system batteries or high-load batteries, the design of HD-20 23mm High Lead-Acid Battery Safety Vent Plug of Zhejiang Hongda Special Rubber Products Co., Ltd. ensures that it can still maintain efficient gas discharge and sealing functions under long-term high temperature and corrosive electrolyte, avoiding the loss of sealing performance due to excessive temperature or battery fluid corrosion.
At the same time, the structural design of the HD-20 safety plug also takes into account the combination of corrosion resistance and high temperature resistance. The outer ring diameter (Bezel Diameter) and outer ring thickness (Bezel Thickness) are reasonably matched, so that the battery will not loosen or deform during use.
With the combined advantages of corrosion resistance and high temperature resistance, the HD-20 safety plug improves the safety and durability of the entire battery system. In automotive start-stop systems, electric vehicles and other industrial applications, batteries usually need to withstand high temperatures and corrosion from battery fluids. HD-20 23mm High Lead-Acid Battery Safety Vent Plug from Zhejiang Hongda Special Rubber Products Co., Ltd. provides a powerful solution. Its sealing performance, pressure regulation capability and high stability in long-term use enable the battery to maintain high efficiency and stable operation under high-load conditions such as long-term high temperature and frequent charge and discharge.
