When leaks occur in inner tubes of automobiles, tractors, tricycles, bicycles, etc., it is difficult to check the location of leaky micropores, and it is difficult to repair them using the usual methods. For this purpose, several simple repair methods are introduced for your reference. 1. Infuse Talc powder method: Twist down the copper nut on the inner tube valve, pull out the valve core, and let the gas in the inner tube go out; then use a hard paper roll to form a small conical funnel and insert it on the gas door. Then, according to different car tires, take different weights of talc, general tricycles, bicycle inner tube 100 grams, small tractors, motorcycle inner tube 200 grams, cars, large and medium-sized tractor inner tube 300 grams. The talcum powder is poured into the inner tube through the valve from the paper hopper. If the irrigation is not completed, the wheel can be rotated for a few more times; the valve core is filled and the copper nut on the inner tube valve is tightened to inflate the inner tube and inflate the tube. In the middle, turn the runner several times to spread the talcum powder inside the inner tube. After the inner tube is inflated, the talcum powder is on the inner wall of the inner tire. This can plug tiny air holes so that they do not leak. 2, infusion white plastic law: Milky white plastic carpentry commonly used chemical adhesive, infuse into the car inside the milk white glue, repair leaks of micro-holes have a good effect. The amount used is generally: tricycles, bicycle inner tube 40 grams, small tractors, motorcycle inner tube 120 grams, respectively before use, need to be mixed with 2 times the weight of fresh water, diluted and then used after mixing. When infusion, dropper can be used, and eyedropper can be used instead of eyedropper. Dilutions filled with milky white glue are instilled into the inner tube through the doorway as described above. After dripping, the wheel will quickly rotate several times, and then the valve core will be installed and the copper nut will be screwed on so that the white latex emulsion will spread evenly to the inner wall of the tire so that the leaking micro-holes can be blocked. 3, perfusion gasoline method: First release the inner tube of the gas, and then use a pipette or eye drops to inhale gasoline, from the gas door drops into the inner tube. Tricycles and bicycles dribble around 8 drops, and cars, large tractors and motorcycles drop about 15 drops. Immediately after dropping, install the valve core, tighten the brass nut, and inflate the inner tube. When the pressure in the inner tube rises, the gasoline molecules will dissolve the rubber surface of the inner wall into a paste, and the plate will soon become one. The gas leaked pores were closed, preventing further leakage of gas. The simple method of repairing the tires above is only suitable for tiny pores that leak slowly, such as slight degumming at the original repair site, aging of the inner tube, and fine blisters. If interior tires are punctuated by sharp objects into large loopholes, the use of simple repair methods is ineffective and must be sent to the repair department for repair.
