Measurement of Refractive Indices of Semi-transparent Oils Using LFI Method
The formulation, the technological conditions and the product properties of polyurethane materials for low density long fiber injection (LFI) process were studied.
對低密度長玻璃纖維注*工藝(LFI)用聚氨酯材料的*、工藝條件和製品*能進行了研究。
這主要應歸因於兩方面的原因:由於LFI反應中產生的熱量,封閉塗層會變形,不同層之間的線*膨脹係數不同。
