There are thousands of roads, and safety comes first. When driving, the most important thing is safety. Among them, the safety of tires is very critical. Everyone who has driven a car knows that it is inevitable that the tire will be punctured by sharp objects such as nails. Once improperly handled, it will cause irreparable losses. Generally speaking, after the tire is punctured, it is no longer suitable for driving. It should be repaired or replaced immediately. However, many vehicles do not have a spare tire, and because of the long distance, it is impossible to drive to the tire shop. In the end, it can only spend a lot of time and money waiting for the trailer to be rescued.
In order to solve this problem, major tire companies have been developing self-repairing tires. At present, the self-repairing tires of many brands on the market are sprayed with self-repairing materials on the basis of ordinary tires. When the air is inflated, the air pressure in the tire instantly fills this layer of soft rubber into the leakage hole to prevent air leakage. This is the so-called self-repairing anti-puncture tire. Generally, as long as the nail diameter is less than 5 mm, even if the nail is removed, it will instantly repair the air-tightness.
Although self-healing tires have unique advantages, these types of tires are not very popular in the market so far. What is the reason? From the technical analysis, the current puncture anti-leakage self-healing tire rubber protective layer is sprayed Spraying rubber on the inner wall of the tire makes the entire production process more complicated.
First of all, spraying production requires the purchase of expensive spraying equipment, and the production cost of the product is high; second, the spraying process requires high-temperature heating and melting of the rubber, and the melting and spraying process will generate a lot of smoke, and the emission of smoke will cause environmental pollution; Third, in order to improve the adhesion between the rubber and the tire, the inner surface of the tire needs to be cleaned and sanded before spraying, and the inner surface of the tire should be cleaned of release agent oil stains, improperly handled or inadequately cleaned and polished, and the tire is running. The phenomenon of rubber falling off, flanging, shifting and rubber accumulation will occur, and excessive grinding will damage the inner liner of the tire, and the tire is prone to slow air leakage; fourth, the rubber used in spray processing is resistant to high temperature The performance of the tire is poor. As the temperature rises in the use of the tire, it is easy to cause the rubber to soften and the rubber strength to deteriorate. It should be known that the softening point of this type of hot melt adhesive is usually around 70 degrees, and it is very easy to degummed and flow in summer. As a result, the tire's self-sealing and leak-proof effect is ineffective, and the increase in temperature will also reduce the adhesiveness of the rubber, leading to the phenomenon of rubber falling, flanging, shifting and rubber accumulation, which brings safety hazards to driving. Many car owners who have used this type of self-repairing tires reported that the rubber inside the tires will flow to the bottom and solidify. This is also the most critical reason why self-repairing tires are currently difficult to be widely popularized.
To sum up, the traditional self-repairing tire spraying process can not only not protect it, but it will bring new hazards to the vehicle. In order to overcome this technical difficulty, many tire companies at home and abroad have invested a lot of money in research and development. Although the brands that develop self-repairing safety tires are mostly international brands, it is fortunate that domestic tire companies have achieved "curving overtaking" on this project in one fell swoop, taking the lead in developing a new generation of self-repairing that perfectly solves technical pain points. Safety tires.
Self-sealing Safety Tire (Guangdong) Co., Ltd.’s fifth-generation integrated molding vulcanized self-healing tire technology is for the public. This is Self-sealing Safety Tire (Guangdong) Co., Ltd. through years of in-depth cooperation with Wanli Tire Co., Ltd. Design and processing technology optimization, the world's first fifth-generation self-repairing tire is produced through a new generation of punctured, air-proof, self-sealing rubber layer tire processing technology.
The fifth-generation self-healing tire comes with an integrated repair function, even if it is pierced by a nail with a diameter of 6mm, there will be no air leakage. Moreover, the speed level of the tire can reach the W level, that is, 270 kilometers per hour, which can be used in complete vehicle assembly of high-end models. Regardless of safety or other technical parameters, they are far superior to the fourth-generation self-repairing tires produced by traditional spraying technology.
The new technology is simple to produce, the production enterprise does not need to add new equipment, the production cost is low, and the product quality is good. Different from the previous production process of inner-coated self-sealing safety tires, the fifth-generation integrated molding vulcanized self-repairing tires are made of rubber patch materials with puncture, air-leakage and self-sealing functions during tire molding and vulcanization. It is covered on the surface of the inner liner of the tire and is compounded by high-temperature conventional vulcanization. It avoids the problems of slow air leakage, rubber flow and shedding caused by improper cleaning and polishing of the inner surface. The traditional self-repairing tire dynamic balance problem that car owners worry about has also been perfectly solved in this new generation of products.
"The fifth-generation integrated vulcanized self-healing tire completely solves the problem that the previous generation products are prone to flow deformation or pollution when used under harsh conditions such as high temperature. It has a broad market prospect.", Wanli Tire Research Institute President Guan Shengxin is also full of confidence in the new generation of self-repairing tires.
In recent years, Wanli Tire has invested a lot of manpower and financial resources in the development of new materials and new technologies. The fifth-generation self-repairing tire is one of the important research results. Now it has developed three series of large cars, small cars and motorcycles. The self-repairing safety tire products have a number of national patented technologies.
With the continuous maturity of technology and the vigorous promotion of enterprises, self-repairing safety tires will become more and more popular with people and businesses. The problem can also be solved. It is foreseeable that the fifth-generation self-repairing tire is expected to become the new vane of the tire industry in the future due to its unique advantages.
