The spinning technics of semi-worsted spinning equipment was used to spin the blended yarn.
通过对竹纤维、绢丝、羊绒混纺原料的性能分析,提出利用半精纺设备开发竹纤维混纺产品,使竹纤维混纺产品具备了多种原料的特点,且服用性能好。
As the quality of 8B and 20# aviation engine oils from soft wax cracking is unstable and product yield is low, the semi-refined wax was used as feedstock of optimized cracking process to produce C5～13 normal alpha olefins, which are synthesized to yield the base oil of 8B and 20# aviation engine oils.
针对8B和20号航空润滑油产品质量不稳定、产品收率低等难题,在优化裂解工艺的基础上,以半精炼蜡裂解生产的C5～C13正构α-烯烃为原料,同时合成8B和20号航空润滑油。
