输送带的翻修也分成翻新和修补两类
输送带的翻修也分成翻新和修补两类。旧输送带经验收,根据尺寸变化、蛇行程度、割伤大小等分成三级: A、级援盖胶有磨损,但不露布.无贯穿性损伤,有效宽度与原品相同;B、级输送带表面部分露布(占5%).有效宽度无减少;C、级露布部分较多,有效宽度减少<50mm。
Conveyor belt renovation is also divided into two categories: renovation and repair. The old conveyor belt can be divided into three levels according to size change, snake degree and cut size: A, grade cover adhesive has wear but not exposed, no penetrating damage, effective width is the same as the original product; B, grade conveyor belt surface part exposed (5%) effective width has not decreased; C, grade exposed part more, effective width reduced < 50 mm.
一般根据分级初步决定是否翻修及翻修类型,然后对原品进行带芯种类、拉伸强度、附着强度等物性试验,进一步判断是否可翻修,确定翻修类型和使用的原材料。对可以翻新的,剥除全部覆盖胶,对需修补的只要剥离部分覆盖胶。剥离后的输送带再经过打磨,除去带芯上残余的橡胶,切除带芯上腐蚀或破损的部分,涂上胶浆,干燥后贴合已擦胶的帆布,最后再贴上筱盖胶。然后用平板蒸汽硫化或低温硫化,再经修理加工得翻新成品。
Generally, according to the classification, it is preliminarily decided whether to renovate and the type of renovation. Then, the physical properties of the original product, such as core type, tensile strength and adhesion strength, are tested to further determine whether it can be renovated and determine the type of renovation and the raw materials used. For those that can be renovated, strip all the covering glue, and for those that need to be repaired, strip only part of the covering glue. After stripping, the conveyor belt is polished to remove the residual rubber on the core, remove the corroded or damaged parts on the core, coat with glue, dry and adhere to the rubbed canvas, and finally stick with Xiao Jiao glue. Then, flat steam vulcanization or low temperature vulcanization were used, and the renovated products were obtained after repair and processing.
