玻璃钢夹砂管道的主要成型工艺
Main forming process of FRP sand pipe
由计算机控制，在芯模上按假山制作 不锈钢铸件 铝箔真空袋 七孔梅花管 hdpe硅芯管 液压钢坝 PVC软管 飞行激光打标机 沥青保温泵规定的与纤维缠绕玻璃钢管相同的工艺制造内衬，凝胶后按设计好的线型和厚度缠绕结构层，并将石英砂与树脂混合的砂浆缠在结构层中，后缠绕外保护层。
By computer control, the inner liner is manufactured on the core mould according to the same process as the filament wound glass fiber reinforced plastic pipe. After the gel is made, the structure layer is wrapped according to the designed line shape and thickness, and the mortar mixed with the quartz sand and the resin is wrapped in the structural layer, and then the outer protective layer is wound.
