玻璃钢管道制作流程 Production process of fiberglass pipe 　　1、清理模具，要求光滑平整；在模具表面环向缠绕聚酯薄膜，作为脱模用。 1. Clean up the mould, and request smooth and smooth; The surface of the die is wrapped in a winding polyester film, which is used as a deform. 　　2、制作内衬层： 2. Make lining layer: 　　在模具上，使用加入一定比例催化剂和促进剂的树脂，由微机控制配比并将树脂均匀喷涂在模具表面，依次由里到外分别使用无碱玻璃纤维表面毡等短纤维织物增强，并用网状物进行气泡赶除，使其整体密实。进行内衬固化。 On the mold, the use of a certain proportion to join resin catalyst and promoter, is controlled by a microcomputer proportioning and resin spray evenly in the mold surface, respectively, in turn, by inside and outside use non-alkali glass fiber surface felt short fiber fabric reinforced, and drive it bubbles with the mesh, make its compact as a whole. The lining solidifies. 　　3、缠绕层、夹砂层及外保护层的制作： 3. Production of winding layer, sand layer and outer protective layer: 　　将设计好的工艺参数输入微机，由微机控制用浸透树脂的无碱玻璃纤维纱进行缠绕直至内部缠绕层厚度。随即进行环向夹砂操作，并由带上较大张力的裹砂材料和环向无碱纤维纱进行密实缠绕，直至设计的夹砂层厚度。同上述内缠绕过程按规定厚度制作外缠绕层。管道的插口毛坯由微机控制随缠绕同步制作。 The design process parameters are entered into microcomputer, which is controlled by microcomputer and is controlled by the non-alkali glass fiber yarn of impregnated resin until the thickness of the inner winding layer is carried out. The ring is then used to operate the sand, and it is tightly wound with the material of sand and ring to the non-alkali fiber yarn, until the thickness of sand layer is designed. In the same inner winding process, the outer winding layer is produced according to the specified thickness. The blank of the pipe is produced by the microcomputer control. 　　4、修整、脱模： 4. Dressing and stripping: 　　待管道固化后，用对应规格的磨刀，修整出双“O”型槽，并在其表面均匀涂上树脂。同时切其承口毛坯。待双“O”型槽上的树脂固化不粘手后，用液压脱模机将管道和模具分离，并在其管道中间部分按要求作标记。 After the pipeline solidifies, the double "O" groove is repaired with the corresponding grinding knife, and the resin is coated evenly on the surface. At the same time, cut the blank. After curing the resin curing on the double O groove, the pipe and die are separated by hydraulic mould, and the middle part of the pipe is marked as required.
