Kev piav qhia
CAS 109-99-9 Tetrahydrofuran (THF) yog ib qho zoo heev organic solvent dav siv nyob rau hauv ntau yam lag luam xws li tshuaj, polymers, thiab coatings.Peb THF yog los ntawm cov neeg muag khoom txhim khu kev qha hauv Suav teb thiab yog qhov zoo tshaj plaws.Nws yog xim tsis muaj xim, flammable, thiab muaj viscosity tsawg, ua rau nws zoo tagnrho hnyav rau ntau daim ntawv thov.Tsis tas li ntawd, peb THF yog tus nqi sib tw, ua rau nws muaj txiaj ntsig zoo rau koj cov kev xav tau hnyav.
Tetrahydrofuran (THF) yog cyclic ether nrog cov tshuaj formula (CH₂)₄O thiab feem ntau yog siv los ua cov kuab tshuaj hauv ntau yam lag luam.Peb CAS 109-99-9 THF yog los ntawm cov neeg muag khoom txhim khu kev qha hauv Suav teb thiab yog qhov zoo tshaj.Nws yog cov kua tsis muaj xim, flammable nrog lub viscosity tsawg, ua rau nws yog ib qho hnyav hnyav rau ntau daim ntawv thov.
Ib qho txiaj ntsig tseem ceeb ntawm peb THF yog nws qib purity siab, nrog qhov tsawg kawg nkaus purity ntawm 99.9%.Qhov siab ntawm purity no ua kom ntseeg tau tias peb THF tsis pub dawb los ntawm impurities uas tuaj yeem cuam tshuam rau koj cov khoom zoo.Tsis tas li ntawd, peb cov THF muaj cov ntsiab lus dej tsawg, uas ntxiv dag zog rau nws cov purity.
Peb THF kuj yog tus nqi sib tw, ua rau nws muaj txiaj ntsig zoo rau koj cov kev xav tau hnyav.Qhov no ua rau nws yog qhov kev xaiv txaus nyiam rau cov lag luam tab tom nrhiav kom txo lawv cov nqi tsim khoom yam tsis muaj kev cuam tshuam rau qhov zoo.
Hais txog kev siv, THF tau siv dav hauv kev lag luam kws tshuaj raws li cov tshuaj tiv thaiv hnyav thiab ua ib feem hauv cov tshuaj formulations.Nws kuj tseem siv rau hauv kev tsim cov polytetramethylene ether glycol (PTMEG), uas yog siv rau hauv kev tsim cov spandex thiab lwm yam elastomers.Tsis tas li ntawd, THF yog siv los ua cov kuab tshuaj hauv kev tsim cov coatings, adhesives, thiab luam ntawv inks.
Ib qho ntawm cov khoom tshwj xeeb ntawm THF yog nws lub peev xwm los yaj ntau yam ntawm cov organic tebchaw, suav nrog cov polymers xws li polyvinyl chloride (PVC) thiab polyvinylidene fluoride (PVDF).Cov cuab yeej no ua rau THF ua cov kuab tshuaj zoo tshaj plaws rau kev ua cov ntaub ntawv polymer, xws li polymer blending thiab film casting.
Thaum nws los txog rau kev tuav thiab khaws cia, peb THF tau muab rau hauv cov ntim khoom zoo kom muaj kev nyab xeeb kev thauj mus los thiab khaws cia.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias THF yog cov nplaim hluav taws kub heev thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, qhov cua zoo kom deb ntawm qhov chaw ntawm qhov hluav taws kub.
Hauv kev xaus, peb CAS 109-99-9 THF yog cov khoom lag luam zoo, cov nqi sib tw uas zoo tagnrho rau ntau yam kev siv hauv ntau yam lag luam.Nws cov qib siab purity siab, cov ntsiab lus dej tsawg, thiab muaj peev xwm yaj ntau yam ntawm cov organic tebchaw ua rau nws muaj ntau yam thiab muaj txiaj ntsig zoo rau cov lag luam nrhiav kev txhim kho lawv cov txheej txheem tsim khoom thiab txo cov nqi.Tiv tauj peb hnub no kom paub ntau ntxiv txog peb THF thiab nws yuav pab tau koj li cas.
