The spinning technics of semi-worsted spinning equipment was used to spin the blended yarn.
通過對竹纖維、絹絲、羊絨混紡原料的性能分析,提出利用半精紡設備開發(fā)竹纖維混紡產(chǎn)品,使竹纖維混紡產(chǎn)品具備了多種原料的特點,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.
針對8B和20號航空潤滑油產(chǎn)品質(zhì)量不穩(wěn)定、產(chǎn)品收率低等難題,在優(yōu)化裂解工藝的基礎上,以半精煉蠟裂解生產(chǎn)的C5~C13正構α-烯烴為原料,同時合成8B和20號航空潤滑油。
