橡膠膨脹節顯露出來顯露出來裂縫縫的原因是由于頭部的強度必較低，那末假設是膠接方法不準確，可曲撓橡膠膨脹節的強度就會更加低，如開刀、打磨時.及下一層布、打磨過度、搭接長度不夠、階梯個數不夠、可曲撓橡膠膨脹節所用橡膠機能非常不好或已經自硫失掉效勞、鋼絲繩打磨過度、鋼絲繩生銹等，接頭部位的強度將會大打折，在運用時，輕易泛起接頭部位斷開的現象。一樣物質情形下，輸送帶接頭處的強度比正常帶體的強度要低。

　　Rubber joint was revealed the cause of the crack seam is due to the strength will lower the head, then hypothesis is cementing method is not accurate, in a flexible rubber joint strength will be more low, such as operation, grinding. And the next layer of cloth, burnish excessive, not enough lap length, number of steps, in a flexible rubber joint function of the rubber is very bad or sulfur has since lost service, wire rope grinding excessive, rust, etc., the strength of the joint parts will be big discount, when using, flush joint parts easily broken.Under the same material condition, the strength of the conveyor belt joint is lower than that of the normal belt body.

　　想要防止可曲撓橡膠膨脹節的顯露出來裂縫，我們在平時的運用中就要留意對其進行盡量照顧，依照上面所說的的操縱就可以了，我們有機遇減少斷開的大事發生。當我們用機械方式聯接時，接頭強度僅能達到帶體強度的百分之四十至百分之五十，冷膠方式品質比較好時，可曲撓橡膠膨脹節強度能達到百分之六十至百分之七十，而熱膠接頭強度能達到百分之八十至百分之九十，要保證接頭方法準確、無品質欠缺。還有輕易造成裂開的原因是，假設輸送帶不覺得合適而運用封口膠、或膠接頭的方向不準確的時刻，接頭部位顯露出來裂縫的物質情形也是正常的。

　　To prevent cracks in flexible rubber joints, we should pay attention to take care of them in daily use, according to the above mentioned manipulation is ok, we have the opportunity to reduce the event of disconnection.When we join in mechanical way, joint strength can only reach forty percent to fifty percent of the belt body strength, the way of cold glue quality is better, in a flexible rubber joint strength can reach sixty percent to seventy percent, and the intensity of hot glue joint can reach eighty percent to ninety percent, to guarantee the accuracy of the method of joint, there is no lack of quality.There are easily caused by the cause of cracking, assuming that the conveyor belt is not feel appropriate and the use of sealant, or glue joint direction is not accurate, joint parts exposed cracks of the material situation is normal.
