汽车轮胎在运行中被利物刺穿,通常用硫化补洞法由专业厂修补。一个20毫米左右的刺孔,修补费用需10～13元,且需10余天甚至更多时间。在硫化中,又会使帘线拉力降低。这种方法费时不经济,质量也存在问题。丹东第一运输公司周成敏同志,参考国内外轮胎的堵孔经验,搞出了一套轮胎补洞塞。用这种补洞塞半年来修补25毫米以下刺孔轮胎五十多条,这些轮胎至今已行驶四万多公里,没发现任何脱落及刺孔扩大现象。经验证明,这些补洞塞牢固地堵住了洞孔,并增强了帘线的抗折断能力,免受了泥砂、水气的侵蚀,很好地保护了胎体。这种轮胎补洞塞适于各种汽车、拖拉机的轮胎,修补又十分方便。尤其经济,一个小洞的修理费用在4元钱以下。因此,这种补洞塞深受广大司机和轮胎修理工的欢迎。
Car tires were run through the piercing of goods, usually made of cured fill holes by the professional factory repair. A puncture about 20 mm, repair costs need 10 to 13 yuan, and more than 10 days or more time. In vulcanization, it will reduce the cord pull. This method is time-consuming and uneconomical, and there are problems with quality. Comrade Zhou Chengmin, the first transportation company in Dandong, made a set of tire fill plug with reference to the plugging experience of domestic and foreign tires. This kind of stuffing plug has been used to repair more than 50 punctured tires below 25mm in the past six months. These tires have traveled more than 40,000 kilometers so far and no signs of any shedding or punctures have been found. Experience has shown that these fill holes firmly plug the hole, and enhance the cord breakage resistance, from the sand, water and gas erosion, well protected the carcass. This tire fill plug for a variety of cars, tractor tires, repair and very convenient. In particular, the cost of repairing a small hole is less than 4 yuan. Therefore, this hole plug by the majority of drivers and tire repair welcome.
