Kev piav txog
CAS 109-99-9 TetrahyDrofuran (THF) yog cov qauv zoo organic zoo li cov tshuaj xws li cov tshuaj yeeb tshuaj, polymers, thiab txheej. Peb tus thf yog los ntawm cov neeg muag khoom kom txhim khu kev qha nyob hauv Suav teb thiab yog ntawm kev ua tau zoo tshaj. Nws yog xim tsis muaj kob, nrog, thiab muaj viscosity qis, ua rau nws muaj kuab tshuaj zoo tshaj rau ntau daim ntawv thov. Tsis tas li ntawd, peb qhov thf yog tus nqi sib tw, ua kom nws cov tshuaj zoo rau koj cov kev xav tau.
TetrahyDrofuran (THF) yog Cyclic Ethaws nrog cov mis nyuj (ch chemical) ₄o thiab feem ntau siv raws li cov kuab tshuaj nyob rau ntau yam kev lag luam. Peb CAS 109-99-9 Thf yog los ntawm cov neeg muag khoom kom ntseeg tau hauv Suav teb thiab yog qhov zoo tshaj plaws. Nws yog cov kua tsis muaj kob, ua kua nrog cov viscosity qis, ua rau nws muaj kuab tshuaj zoo tshaj rau ntau daim ntawv thov.
Ib qho ntawm qhov zoo ntawm peb THF yog nws theem siab purity, nrog tsawg kawg ntawm 99.9%. Qib siab ntawm kev coj dawb huv uas peb tus thf yog pub dawb los ntawm impurities uas tuaj yeem cuam tshuam rau qhov zoo ntawm koj cov khoom. Ib qho ntxiv, peb tus thf muaj cov ntsiab lus dej qis, uas ntxiv rau nws txoj kev coj dawb huv.
Peb Thf kuj tau muaj tus nqi sib tw, ua rau nws muaj kev daws teeb meem zoo rau koj cov kev xav tau. Qhov no ua rau nws muaj kev saib xyuas zoo rau kev lag luam nrhiav kom txo lawv cov nqi ntau lawm yam tsis muaj kev sib cuam tshuam ntawm kev ua tau zoo.
Nyob rau hauv cov nqe lus ntawm cov ntawv thov, Thf tau siv dav hauv kev lag luam kws tshuaj yog cov tshuaj tiv thaiv thiab raws li kev sib xyaw ua ke hauv cov qauv tshuaj. Nws tseem siv rau hauv kev tsim cov polytetramethylene auther glycol (ptmeg), uas yog siv hauv kev tsim cov spandex thiab lwm yam elastomers. Ib qho ntxiv, Thf yog siv los ua cov kuab tshuaj nyob hauv kev tsim cov txheej txheej, cov nplaum, thiab cov ntawv luam tawm.
Ib qho ntawm cov khoom tshwj xeeb ntawm Thf yog nws lub peev xwm los yaj ntau cov organic xws li polyvinyl stroride (pholinylidene fluoride (PVDF). Cov cuab yeej no ua rau Thf ib qho kev siv tau zoo tshaj plaws rau cov ntawv thov polymer ua, xws li polymer ua ke thiab zaj duab xis Casting.
Thaum nws los rau kev tuav thiab cia, peb tus thf yog muab rau hauv cov ntim khoom zoo los xyuas kom muaj kev thauj mus los nyab xeeb thiab chaw khaws cia. Nws yog ib qho tseem ceeb kom nco ntsoov tias thf yog cov nplaim taws heev thiab yuav tsum tau muab cia rau thaj chaw txias, qhuav, muaj qhov cua txias kom qhuav ntawm cov khoom siv ntawm kev tiv thaiv.
Hauv kev xaus, Peb Li Cas 10999-999-999- zoo, kev sib tw luv nqi uas yog qhov zoo tagnrho rau ntau yam kev lag luam. Nws theem siab heev, cov dej qis cov ntsiab lus, thiab kev xaiv cov khoom siv organic ua rau nws cov txheej txheem ntau lawm thiab txo tus nqi. Tiv tauj peb los ntawm peb xav paub ntau ntxiv txog peb THF thiab yuav ua li cas nws tuaj yeem pab tau koj txoj kev lag luam.
