玻璃钢风机叶片模具整体翻新方法
摘要：
本发明公开了一种玻璃钢风机叶片模具整体翻新方法，包括：将预翻新玻璃钢风机叶片模具表面切除8-10毫米厚度；在切除后的所述预翻新玻璃钢风机叶片模具表面均匀钻设通孔；将风机叶片标准样件放置于另一半玻璃钢风机叶片模具中，在所述风机叶片标准样件表面制作所述预翻新玻璃钢风机叶片模具的表层壳体；将表面刷涂有乙烯基酯树脂的所述预翻新玻璃钢风机叶片模具扣合在刷涂有乙烯基酯树脂和无碱无捻短切纤维纱胶泥的所述风机叶片标准样件上后闭合加压，室温固化后取下打磨。本发明采用上述流程的玻璃钢风机叶片模具整体翻新方法，能够提高模具的返修效果，延长模具的使用寿命。
摘要（英）：

The invention discloses a method for entirely renovating a fiber glass reinforced plastic fan vane mold, which comprises the steps of: cutting off the surface of the fiber glass reinforced plastic fan vane mold to be renovated by a thickness of 8-10 millimeters; drilling holes uniformly on the surface of the fiber glass reinforced plastic fan vane mold to be renovated after cutting; placing a fan vane standard simple in the other half fiber glass reinforced plastic fan vane mold; making a surface casing for the fiber glass reinforced plastic fan vane mold to be renovated on the surface of the fan vane standard simple; and after buckling the fiber glass reinforced plastic fan vane mold of which the surface is coated with vinyl ester resin on the fan vane standard simple coated with vinyl ester resin and alkalifree twist-less chopped fiber yarn plaster, closing, pressurizing, curing at a room temperature, and grinding. The method has the advantages that the repairing effect of the mould can be improved, and the service life of the mould can be prolonged.
