shrinkage control meaning in English
留矿法放矿控制
收缩度控制
Examples
- For poly ( vinyl acetate ) based lpas , it seemed that lpas with higher molecular weights worked better than that with the lower molecular weights and lpa with low molecular weights need high concentration for good shrinkage control
对于聚苯乙烯类的lpa - c ，试样收缩控制效果随着lpa - c浓度的增加而增强；对于聚醋酸乙烯酯类的lpa ，分子量较高的lpa比分子量较低的lpa的收缩控制效果好；分子量较低的lpa若要达到较好的收缩控制效果则需要较高的浓度。 - In our work , many methods were used to study the shrinkage control mechanism of unsaturated polyester resins with low profile additives cured at low - medium temperatures , including a dilatometer for volume change which was designed and developed in our laboratory , and sem for morphology
本文的目的是研究加入低轮廓添加剂的不饱和聚酯树脂在中低温下固化的收缩控制机理。成功的试制了能够测量树脂固化体积变化的膨胀仪；用sem观察了试样固化后的最终形态。 - 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
在膨胀研究中，发现适当的温度条件更有利于upr达到好的收缩控制效果；不同类型的lpa随着偶极矩、玻璃化温度、与upr的相容性、与upr的混合形态的不同，表现出不同的收缩控制效果；聚醋酸乙烯酯类的lpa - a存在一个最佳收缩控制的浓度范围，在这个范围之内， lpa起到补偿收缩的作用；而在这个范围之外， lpa的作用仅相当于填料，不能起到收缩控制。
