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?

　　氣流攪拌是利用氣體鼓泡通過液 體層，對液體產(chǎn)生攪拌作用，或使氣泡群一密集狀態(tài)上升借所謂上升 作用促進(jìn)液體產(chǎn)生對流循環(huán)。與機(jī)械攪拌相比，僅氣泡的作用對液體 進(jìn)行的攪拌時比較弱的，對于幾千毫帕·秒以上的高粘度液體是難于 使用的。但氣流攪拌無運動部件，所以在處理腐蝕性液體，高溫高壓 條件下的反應(yīng)液體的攪拌時比較便利的。在工業(yè)生產(chǎn)中，攪拌操作時從化學(xué)工業(yè)開始的，圍繞食品、纖維、造紙、石油、水處理等，作為工 藝過程的一部分而被廣泛應(yīng)用。攪拌操作分為機(jī)械攪拌與氣流攪拌。
                  

　　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.                

　　輪胎磨損

　　Tire wear

　　由于車感不佳，很多新手都喜歡原地打方向，這個壞習(xí)慣基本上是從駕校里面帶出來的。原地打方向會令輪胎的磨損集中在同一個接觸面上，造成輪胎局部嚴(yán)重磨損，縮短使用壽命。因此，司機(jī)應(yīng)避免原地打方向，而應(yīng)該在輪胎滾動時打方向，這樣的話，地面給攪拌車輪胎帶來的才是全方位且均勻的正常磨損。

　　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.
