橡膠膨脹節(jié)顯露出來(lái)顯露出來(lái)裂縫縫的原因是由于頭部的強(qiáng)度必較低，那末假設(shè)是膠接方法不準(zhǔn)確，可曲撓橡膠膨脹節(jié)的強(qiáng)度就會(huì)更加低，如開(kāi)刀、打磨時(shí).及下一層布、打磨過(guò)度、搭接長(zhǎng)度不夠、階梯個(gè)數(shù)不夠、可曲撓橡膠膨脹節(jié)所用橡膠機(jī)能非常不好或已經(jīng)自硫失掉效勞、鋼絲繩打磨過(guò)度、鋼絲繩生銹等，接頭部位的強(qiáng)度將會(huì)大打折，在運(yùn)用時(shí)，輕易泛起接頭部位斷開(kāi)的現(xiàn)象。一樣物質(zhì)情形下，輸送帶接頭處的強(qiáng)度比正常帶體的強(qiáng)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(jié)的顯露出來(lái)裂縫，我們?cè)谄綍r(shí)的運(yùn)用中就要留意對(duì)其進(jìn)行盡量照顧，依照上面所說(shuō)的的操縱就可以了，我們有機(jī)遇減少斷開(kāi)的大事發(fā)生。當(dāng)我們用機(jī)械方式聯(lián)接時(shí)，接頭強(qiáng)度僅能達(dá)到帶體強(qiáng)度的百分之四十至百分之五十，冷膠方式品質(zhì)比較好時(shí)，可曲撓橡膠膨脹節(jié)強(qiáng)度能達(dá)到百分之六十至百分之七十，而熱膠接頭強(qiáng)度能達(dá)到百分之八十至百分之九十，要保證接頭方法準(zhǔn)確、無(wú)品質(zhì)欠缺。還有輕易造成裂開(kāi)的原因是，假設(shè)輸送帶不覺(jué)得合適而運(yùn)用封口膠、或膠接頭的方向不準(zhǔn)確的時(shí)刻，接頭部位顯露出來(lái)裂縫的物質(zhì)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.
