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.
对低密度长玻璃纤维注*工艺(LFI)用聚氨酯材料的*、工艺条件和制品*能进行了研究。
这主要应归因于两方面的原因：由于LFI反应中产生的热量，封闭涂层会变形，不同层之间的线*膨胀系数不同。
