1、輸送帶底層簡(jiǎn)單起皺，導(dǎo)致輸送帶分層脫膠等問(wèn)題。
1. The simple wrinkling of the bottom layer of the conveyor belt leads to the delamination and degumming of the conveyor belt.
如果輸送帶變形、起皺，下面的橡膠和結(jié)構(gòu)材料也會(huì)變形，人們采用剪切的方法，會(huì)導(dǎo)致與橡膠和結(jié)構(gòu)材料相連的局部區(qū)域被破壞，并且會(huì)出現(xiàn)皮帶和頂部之間的分離力。時(shí)間長(zhǎng)了，輸送帶更終會(huì)分層脫膠。
If the conveyor belt is deformed and wrinkled, the rubber and structural materials under it will also be deformed. If people use the method of shearing, the local area connected with the rubber and structural materials will be damaged, and the separation force between the belt and the top will appear. After a long time, the conveyor belt will eventually be layered degumming.
2、抗疲勞性下降。
2. Fatigue resistance decreased.
與僅隨彈性結(jié)構(gòu)材料置換應(yīng)力大小變化的拉應(yīng)力效應(yīng)相比，即使波動(dòng)變化平緩，前者的抗疲勞性能也會(huì)顯著下降。
Compared with the tensile stress effect which only changes with the displacement stress of elastic structural materials, the fatigue resistance of the former will decrease significantly even if the fluctuation is gentle.
3、輸送帶的抗沖擊能力下降。
3. The impact resistance of conveyor belt decreases.
帆布的組成決定了輸送帶抗沖擊能力的大小。通常情況下，如果畫布垂直彎曲，則畫布的橫向彎曲度會(huì)提高。那么我們就可以簡(jiǎn)單分析一下橫豎畫布的曲折性，我們可以了解到目前橫豎畫布的情況是非常松懈的。如果現(xiàn)在橫紗處于曲折狀態(tài)，當(dāng)材料撞擊帆布時(shí)，沖擊力主要來(lái)自豎紗力，橫紗只是拉長(zhǎng)彎曲部分，沒(méi)有力，它不會(huì)驅(qū)動(dòng)豎紗外沖擊點(diǎn)用力合起來(lái)，顯然抗沖擊性不好。
The composition of canvas determines the impact resistance of conveyor belt. In general, if the canvas bends vertically, the horizontal curvature of the canvas increases. Then we can simply analyze the twists and turns of horizontal and vertical canvases. We can understand that the current situation of horizontal and vertical canvases is very lax. If the horizontal yarn is in a zigzag state now, when the material strikes the canvas, the impact force mainly comes from the vertical yarn force. The horizontal yarn only elongates the bending part, and there is no force, it will not drive the impact point outside the vertical yarn to force together. Obviously, the impact resistance is not good.
