当夏天的炎热来临时,祖国的山川都是“红色的”,轮胎经不起高温。为了冷却轮胎,许多购物车司机使用直接喷水,但这种方法很容易导致更大的危险。

6月28日凌晨,江阴大桥一辆卡车因轮胎爆炸引发火灾。由于装在汽车上的棉纱是易燃的,因此火灾迅速烧毁了卡车的一侧,并且轧制的棉纱点燃了公路边坡的保护和隔离。在森林继续蔓延之后,火灾迅速被派遣实施救援。

大火很快就消失了。经过初步调查,卡车司机发现事故发生时右后轮胎已经吸烟,因此他将车停在紧急车道上以扑灭火灾。这辆大卡车的司机说道:“我走到前面拿水壶冲了一下水。当我冲了过来,里面的轮胎爆炸了,爆炸开始燃烧。”

消防员提醒说,汽车轮胎是橡胶制品。在夏季,高温和长期摩擦会产生大量的热量。如果使用冷水溅水,会导致橡胶老化和爆炸。因此,一旦轮胎或油路着火,请使用干粉灭火器或使用沙子覆盖火灾。另外,当驾驶员在夏季开车时,必须及时做好车辆维修,提高安全驾驶意识,避免事故发生。

轮胎很热,很水,很危险!

In summer, the temperature is high and the surface temperature will rise. When the drivers drive on the road for a long time, the temperature of the tire will rise sharply. At this time, it will suddenly be poured on a bucket of cold water. The local thermal expansion and contraction will cause the internal structure of the tire to be deformed. The rapid temperature change will make the tires layer. There is a conflict between them. If there is a tire aging situation at the same time, it is very likely that an explosion will occur.

Moreover, ordinary trucks or tractors are also accustomed to adding water tanks to the brake drums or tires. This way not only increases the weight, but also accelerates the aging of the tires. It is like letting you run for ten kilometers under the sun. Take a cold shower, who can afford it?

The correct approach in hot weather

1. Avoid long-distance uninterrupted driving and stagger the high temperature period.

The driver of the cart pulled the goods hard, stayed for a long night, and drove long distances. However, people can still hold on, but the tires can't hold back. Therefore, drivers should first set aside intermittent time when driving, so that the tires naturally cool down. In addition, like the high temperature period at noon, it is a high-rising period of tire puncture, which should be staggered in a planned way.

2. Wash the car after the tire has cooled down.

Watering the tires to cool down is not to say that you can't do it at all, but you can't do it. Generally speaking, in the hot weather, the tire should be naturally cooled down, and then cooled with cold water, so as to prevent the tire from suddenly expanding and shrinking, or bursting the rubber or steel layer and cracking the toe!

Xiaobang said

Summer is the season of concentrated tire problems. Drivers need to pay attention to the water. They should check the tires more carefully, whether the tire pressure is normal, whether the tires are seriously worn, and whether there are foreign objects in the grooves. I want the tires to be safe, and the service is very good.
