Mixer is widely used in chemical industry, many chemical production are more or less used in mixing operation. Today, let's take a simple look at how to carry out air mixing and tire wear from the charging mixer?

　　气流搅拌是利用气体鼓泡通过液 体层，对液体产生搅拌作用，或使气泡群一密集状态上升借所谓上升 作用促进液体产生对流循环。与机械搅拌相比，仅气泡的作用对液体 进行的搅拌时比较弱的，对于几千毫帕·秒以上的高粘度液体是难于 使用的。但气流搅拌无运动部件，所以在处理腐蚀性液体，高温高压 条件下的反应液体的搅拌时比较便利的。在工业生产中，搅拌操作时从化学工业开始的，围绕食品、纤维、造纸、石油、水处理等，作为工 艺过程的一部分而被广泛应用。搅拌操作分为机械搅拌与气流搅拌。
                  

　　Air stirring is the use of gas bubbling through the liquid layer to stir the liquid, or to make the bubble group rise in a dense state. By the so-called rising effect, the liquid is promoted to produce convective circulation. Compared with the mechanical stirring, only the effect of bubbles on the liquid stirring is relatively weak, and it is difficult to use for the high viscosity liquid above several thousand MPa · s. But there are no moving parts in the air stirring, so it is convenient to handle the corrosive liquid and the reaction liquid under high temperature and high pressure. In industrial production, the stirring operation starts from the chemical industry and is widely used as a part of the process around food, fiber, papermaking, oil, water treatment, etc. Mixing operation is divided into mechanical mixing and air mixing.                

　　轮胎磨损

　　Tire wear

　　由于车感不佳，很多新手都喜欢原地打方向，这个坏习惯基本上是从驾校里面带出来的。原地打方向会令轮胎的磨损集中在同一个接触面上，造成轮胎局部严重磨损，缩短使用寿命。因此，司机应避免原地打方向，而应该在轮胎滚动时打方向，这样的话，地面给搅拌车轮胎带来的才是且均匀的正常磨损。

　　Due to the poor feeling of the car, many novices like to play in situ. This bad habit is basically brought out of the driving school. Turning the direction in place will make the wear of the tire concentrate on the same contact surface, causing serious local wear of the tire and shortening its service life. In this way, the tire should be kept from rolling in all directions.
