输送带粘接力缺乏导致接头脱胶的原因大致可分为：资料与施工，即资料质量与施工工艺。下面来详细看下内容吧。
The reasons for the lack of adhesive force of conveyor belt leading to joint degumming can be roughly divided into: data and construction, that is, data quality and construction technology. Now let's take a detailed look at the content.
1、冷硫化接头资料
1. Cold vulcanization joint data
冷粘接头适合于中低强度分层带的快速接头操作，可运用冷硫化粘接剂SK313来达到足够大的粘接强度，冷硫化粘接剂SK313对橡胶、金属、织物、皮革的粘接力超过德国DIN工业标准，达到与热硫化同级，固化后胶层柔韧，环境耐性强，耐老化，接头的曲挠性好。
The cold bonded joint is suitable for the quick joint operation of the medium and low strength layered belt. The cold vulcanized adhesive sk313 can be used to achieve sufficient bonding strength. The adhesion of the cold vulcanized adhesive sk313 to rubber, metal, fabric and leather exceeds the German DIN industrial standard and reaches the same level as the hot vulcanization. After curing, the adhesive layer is flexible, with strong environmental resistance, aging resistance and good flexibility of the joint.
冷粘接头对所运用胶水的粘接性能要求很高，运用一般的胶水，要么粘接力缺乏，要么便是为了进步粘接力，树脂含量高，胶层固化硬度大，抗曲挠性差。而且冷粘接头的施工对于操作人员的技能也有严格要求，比方胶水涂刷的厚度，分次分层涂刷及粘接贴合时胶层干燥程度的判断、织物层间胶层厚度的控制等等。
Cold bonded joints have high requirements for the bonding performance of the glue used. The use of general glue is either lack of bonding force, or it is to improve the bonding force. The resin content is high, the curing hardness of the adhesive layer is large, and the bending resistance and flexibility are poor. Moreover, the construction of cold bonded joints also has strict requirements for the professional skills of operators, such as the thickness of glue brushing, the judgment of the dryness of the adhesive layer when brushing and bonding in layers, the control of the thickness of the adhesive layer between fabric layers, and so on.
冷硫化接头在Z后还需求在接头缝隙处张贴修补条，对粘接面形成保护与加强，防止起层刮伤导致开胶脱胶。
After the cold vulcanization joint is Z, it is also required to post a repair strip at the joint gap to protect and strengthen the bonding surface, so as to prevent the layer scratch from causing the opening and degumming.
2、热硫化接头资料
2. Hot vulcanized joint data
热硫化接头需求热硫化胶浆、热硫化芯胶、面胶，热硫化芯胶填充在输送带的织物层或钢丝绳之间，起填充与粘接效果，具有良好的粘接性，硫化后的曲挠性、柔韧性好。热硫化面胶具有抗拉耐磨的特色，可以在输送带表层形成保护层，进步接头强度，延伸接头运用寿命。假如两种胶料质量差、杂质含量多，在硫化后粘接力很简单缺乏，无法粘接。
Hot vulcanized joints require hot vulcanized mastic, hot vulcanized core rubber and surface rubber. The hot vulcanized core rubber is filled between the fabric layer or steel wire rope of the conveyor belt, which has the effect of filling and bonding, has good adhesion, and has good flexibility and flexibility after vulcanization. The hot vulcanized surface rubber has the characteristics of tensile and wear resistance, which can form a protective layer on the surface of the conveyor belt, improve the strength of the joint and extend the service life of the joint. If the quality of the two compounds is poor and the content of impurities is high, the bonding force after vulcanization is very simple and lacking, so it is impossible to bond.
热硫化胶浆相同起粘接效果，看似与芯胶效果重叠，可是胶浆自身良好的浸润性、流动性使胶浆可以与织物层、钢丝绳完全结合，内部存在的气泡缝隙，确保接头的密实性，一起供给强壮的粘接力，是热硫化接头必不可少的一种资料。
The hot vulcanized adhesive has the same bonding effect, which seems to overlap with the core adhesive effect, but the good wettability and fluidity of the adhesive make the adhesive completely combined with the fabric layer and steel wire rope, eliminate the internal bubble gap, ensure the compactness of the joint, and provide strong bonding force together, which is an indispensable material for the hot vulcanized joint.
山东输送带厂家认为有些热硫化接头脱胶便是由于热硫化胶浆没有运用或运用过少，接头结合度不够，面对强壮的皮带拉力一扯就断。热硫化接头的硫化过程也需求良好的技术与经历，升温过程中同步提升压力，达到硫化温度后保温保压硫化，硫化的时刻要控制好，不能硫化不完全，也不能过硫。
Shandong conveyor belt manufacturers believe that some hot vulcanized joints are degummed because the hot vulcanized mortar is not used or used too little, and the connection degree of the joint is not enough. In the face of strong belt tension, it will break when pulled. The vulcanization process of hot vulcanization joints also requires good technology and experience. During the temperature rise process, the pressure is increased synchronously. When the vulcanization temperature is reached, the vulcanization is carried out with heat preservation and pressure holding. The vulcanization time should be well controlled, and neither incomplete vulcanization nor over vulcanization is allowed.
During the operation of the conveyor belt, the joint is simply degummed. Once the joint of the conveyor belt is degummed, the conveyor belt will not be used, and in serious cases, the whole conveyor line will be paralyzed and damaged.
