Antistatic flame retardant solid tire application case-coal tire

In accordance with the national safety production policy, in order to meet the safety requirements of coal mine explosion and fire prevention, Yantai WonRay Rubber Tire Co., Ltd. has developed antistatic and flame retardant solid tires for use in flammable and explosive environments. The product performance has been tested by authoritative scientific research and testing institutions. Meet or exceed the relevant standard requirements, the product has been widely used in the underground vehicles of well-known domestic mining equipment manufacturing companies, and fully meet the design and use performance of the vehicles.
As the departments in charge at all levels attach importance to safe production, manufacturers in flammable and explosive working environments have put forward more and more stringent requirements on the antistatic, electrical conductivity and flame retardancy of tires. In order to meet market demand, our company has formulated a scientific research project for the development of antistatic, explosion-proof and flame-retardant solid tires.

As we all know, ordinary rubber is a poor conductor of electricity, or even an insulator. The resistivity of unmatched natural rubber can reach 1011 or even 1013 ohms. Therefore, in an environment that requires antistatic and electrical conductivity, the rubber must be formulated and modified. , Make it reach the required resistivity.
During the driving of the vehicle, static electricity will be generated due to the friction between the tires and the ground. At the same time, the metal parts of the car body will also generate static electricity for various reasons. If the static electricity cannot be discharged in time, the charge accumulation will cause a voltage difference to the ground to a certain extent, which will cause discharge Phenomenon, if it is in a flammable and explosive environment, it will cause great safety hazards and even accidents.
In order to introduce the static electricity of the vehicle into the ground, many vehicles use the simplest grounding link method, but there is a hidden danger of incomplete discharge. The anti-static and flame-retardant tires developed by us perfectly solve this problem.

The conductive path of the antistatic tire is to introduce the electric charge generated by various parts of the vehicle into the ground through the body, axle, rim, and tire, which solves the hidden danger of incomplete conduction of the grounding chain; because the tire conduction is continuous, there is no bad contact phenomenon, and at the same time Does not change the appearance of the vehicle and does not add any accessories.

The rubber used in the tire industry is mainly natural rubber and ordinary synthetic rubbers such as styrene butadiene rubber and butadiene rubber. These rubbers are organic and will burn in an aerobic environment and are difficult to extinguish, so they are used in flammable and explosive environments. In addition to antistatic or conductive rubber products, there are also strict requirements for its flame retardancy, such as GB19854-2005 “General Rules for Explosion-proof Technology for Industrial Vehicles for Explosive Environments” and MT113-1995 “Flame Retardant Polymer Products Used in Coal Mines” “General Test Methods and Judgment Rules for Antistatic Properties” stipulates the resistivity and combustion performance.
Focusing on the topic of static electricity and flame retardant, our company’s professional technicians have launched formula development. By adding and adjusting the types and proportions of compounding agents, changing the varieties of raw rubber, after countless experiments and the cooperation of production departments, they finally developed The anti-static, explosion-proof and flame-retardant solid tires have reached or exceeded relevant standards. The anti-static and explosion-proof solid tires of Yantai WonRay Rubber Tire Co., Ltd. have reached GB/T10824-2008 “Pneumatic Tires” after being tested by authoritative scientific research and professional testing institutions. Technical Specifications for Solid Rim Tires, GB/T16623-2008 Technical Specifications for Press-fit Solid Tires, GB19854-2005 General Rules for Explosion-Proof Technology for Industrial Vehicles Used in Explosive Environments, and MT113-1995, Flame Retardant and Antistatic Polymer Products Used in Coal Mines According to the technical requirements of “General Test Methods and Judgment Rules”, the product has been used in flammable and explosive environments, and the results have reached and exceeded the expected results. Now it has produced anti-static, explosion-proof and flame-retardant solid tires for well-known domestic coal mine vehicle manufacturers, which has made its vehicles highly praised in the industry and has a broad market prospect.
