In the volume change study, we found appropriate temperature is helpful for shrinkage control, and different lpas have different shrinkage control effects due to their dipole moment, tg, miscibility with upr and morphology after blending. there existed an optimal concentration range of poly ( vinyl acetate ) based lpas for shrinkage control. lpa was effective for shrinkage compensation in this range, on the other hand, lpa only acted as filler and the low profile effect vanished out of this range, however, for polystyrene based lpa, the more concentration the better shrinkage control
在膨脹研究中,發現適當的溫度條件更有利於upr達到好的收縮控制效果;不同類型的lpa隨著偶極矩、玻璃化溫度、與upr的相容性、與upr的混合形態的不同,表現出不同的收縮控制效果;聚醋酸乙烯酯類的lpa - a存在一個最佳收縮控制的濃度范圍,在這個范圍之內, lpa起到補償收縮的作用;而在這個范圍之外, lpa的作用僅相當于填料,不能起到收縮控制。When nals was used as the collector in the process, the optimal conditions were the ph of feed solution 5. 0 - 6. 0, air flow rate 100ml / min, the liquid column depths 20cm, the surfactant concentration determined by its cmc and feed concentration. under this condition, the 3 can be above 20. also, the optimal ph ( 5. 0 ) was calculated theoretically for the recovery of the cu ( ii )
