燃输送带生产 工艺流程：干燥→塑炼→合炼→混炼→停放→热炼→压延→成型→硫化→包装。与非尼龙骨架输送带有所不同，尼龙分层难燃输送带生产工艺硫化后要经过二次拉伸定型处理。二次拉伸定型主要有两种方法，一种是模内压力下冷却定型方法（以下简称模内定型），另一种是模外拉伸冷却定型方法（以下简称模外定型）。模内定型方法简单，定型效果好。但是采用这种方法定型能耗大，生产效率低。相比之下模外定型方法虽然须多一套拉伸装置，但是采用这种方法后产品质量可靠，生产效率高，适于大批量规模生产
The production process of the conveyer belt is dry to plastic, then mixed, then mixed, then stop, then hot, then calendering, then forming, then sulphur to packaging. Unlike nylon nylon skeleton conveyor, the production process of nylon laminated flame retardant conveyor belt is two times after vulcanization. There are two main methods of drawing two times. One is the cooling setting method under the mould pressure (hereinafter referred to as the internal mold setting), the other is the external mold stretching cooling setting method (hereinafter referred to as the outside die setting). The internal mold setting method is simple and the finalizing effect is good. But with this method, the energy consumption is large and the production efficiency is low. In contrast, there is an extra set of drawing devices, but the product is of reliable quality, high production efficiency and suitable for large scale production.
