The tires of tractors and agricultural transport vehicles are prone to air leakage faults during operation, and even punctures caused by air leakage must be promptly repaired. Here are a few simple repair methods. 1. Emergency repair of leakage of inner tube The inner tube of the tire has a small hole and can be filled with an adhesive plaster. First, clean the hole around the hole with a mallet, and then cut a piece of rubber paste that is larger than the hole, then cut a larger piece of rubber plaster, and paste it on six or seven layers. The tire can keep airtight for a long time. . If the crack is larger, you can use the mallet to clean the inner tube and place it flat on a wooden board. Take a piece of raw rubber used for repairing the tire and attach it to the crack of the inner tube. Then turn on the electric iron and firmly press it tightly. On the rubber cover, the rift can be repaired in a few minutes. If conditions permit, the electric iron can be clamped with a tool such as a clamp inside the inner tube, so that the effect of the tire repair is better. 2. Repair tires with slow leakage Take two tablespoons of talcum powder, remove the valve core from the tire, exhaust the inner tube air, use a hard paper shell to make a funnel to insert the popular door, and put the talcum powder into the inner tube. When the irrigation can not enter the funnel Remove, turn the wheel and refill it until it is finished. Then fill the valve core with sufficient gas. After inflated, talcum powder spreads in the fetus and diffusely attaches to the inner wall of the femur, which can stop the leakage of tiny air holes. 3. Treatment of tire penetration into roots When the tractor is working in the field, the tires are sometimes stung by hard plants. If the leakage is not serious at that time, the tools should be removed as soon as possible, and the tractor should be slowly pulled out of the field before pulling out the roots for repair. Pull out in advance. 4. Treatment of missing valve cover After the valve cover is lost, in order to prevent the valve from entering the earth, a soft plastic pipe with an appropriate inside diameter may be cut, one end is heated and closed with heat, and the other end is placed on the valve mouth; the rubber hose with an appropriate inside diameter may also be used. One end is punctured with a thin wire and one end is placed on the valve. In order to be reliable, it can be fastened with a thin wire. 5. Use tire explosion-proof liquid The tire explosion-proof liquid has the function of instantly repairing the tire air leakage hole and explosion-proof crack. At the same time, it can reduce the temperature of the tire, stabilize the tire pressure, prevent the tire from aging, and prolong the service life of the tire. The reason why the vehicle punctures during the driving process is that most of the tires have small perforations, causing imbalance in the tire's internal pressure and tire burst. The explosion-proof liquid of the tire is in the form of emulsion, and the tire is filled with the emulsion within the tire as the tire rotates. Once the tire is perforated by external force, the perforation will be repaired instantaneously and no leakage of air will occur, which can effectively prevent the tire from bursting. Reduce traffic accidents and protect the safety of vehicles and drivers. Ziprasidone Intermediates
