What is the principle of tire self-sealing fluid?
2 Answers
The principle of tire self-sealing fluid is to form a thin film on the inner tread area of the tire, sealing punctures in the tread area. Below is an introduction about tires: 1. Introduction: A tire is a circular elastic rubber product mounted on various vehicles or machinery to roll on the ground. 2. History: In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government under the title "Improvement in the Wheels of Carriages and Other Vehicles." On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. 3. Function: Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance. Additionally, they are required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
The working principle of tire sealant is quite simple: As an ordinary car owner, I always carry a can as a backup during long trips to save time and effort. When the tire is punctured by a nail or small stone and air starts leaking, the rubber particles or fiber particles in the sealant are drawn to the puncture hole. As air flows out, these particles expand and form a plug to seal the hole. It's like a smart glue that completes the repair automatically without manual intervention. After injecting it into the tire, the liquid evenly coats the inner wall. Once a small hole appears, it reacts instantly to prevent further air loss. However, it's important to note that this product is only suitable for small punctures—larger holes won't be fixed. I've tried it several times, and it generally provides a temporary solution for most situations, giving me peace of mind while driving to a repair shop. When choosing a sealant, check the ingredients: safer formulas use non-corrosive particles that won’t damage the wheel rims, while cheaper options may have side effects. Overall, it makes tire maintenance much easier, especially for drivers like me who frequently travel long distances.
