Tetrahydrofuranyog cov tshuaj sib txuas nrog cov mis molecular mis nyuj c4h8o. Nws yog cov kua tsis muaj kob, cov kua dej nrog cov ntxhiab tsw qab. Cov khoom no yog cov kuab tshuaj uas zoo tshaj plaws hauv ntau yam kev lag luam, suav nrog cov tshuaj, plastics, thiab polymer tsim. Thaum nws muaj qee cov xwm txheej muaj peev xwm, txhua yam, tetrahydrofuran tsis yog cov khoom txaus ntshai.
Ib qho yuav muaj feem yuav muaj kev pheej hmoo ntawmTetrahydrofuranyog nws cov nplaim taws. Cov kua muaj flashpoint ntawm -14 ° C thiab muaj peev xwm ntws tau yooj yim yog tias nws nkag mus rau hauv kev sib cuag nrog ib lub txim, nplaim taws lossis kub. Txawm li cas los xij, qhov kev pheej hmoo no tuaj yeem tswj hwm los ntawm kev khaws cia zoo thiab cov txheej txheem fandling. Txhawm rau txo txoj kev pheej hmoo ntawm hluav taws thiab tawg, nws yog ib qho tseem ceeb kom ua kom cov khoom ntawm cov chaw ignition thiab siv qhov cua.
Lwm qhov muaj peev xwm txaus ntshai ntawmTetrahydrofuranNws puas muaj peev xwm ua rau cov tawv nqaij khaus thiab tshuaj hlawv. Thaum cov kua los ntawm kev sib chwv nrog daim tawv nqaij, nws tuaj yeem ua rau tawv ncauj, liab, thiab o. Qhov kev pheej hmoo no tuaj yeem txo qis kev hnav khaub ncaws hnav uas tsim nyog thiab tiv thaiv thaum tuav cov khoom. Cov hnab looj tes, hnab looj tes, thiab cov khaub ncaws tiv thaiv tuaj yeem tiv thaiv kev tiv thaiv tawv nqaij.
TetrahydrofuranKuj yog cov kua tawm tsam, uas txhais tau tias nws tuaj yeem vaporize tau yooj yim thiab tam sim no ua pa pa. Kev npau taws ntev rau cov vapors tuaj yeem ua rau kiv taub hau, mob taub hau, thiab ua pa. Txawm li cas los xij, qhov kev pheej hmoo no tuaj yeem zam los ntawm kev siv cov khoom lag luam hauv qhov chaw muaj pa zoo thiab tsis txhob muaj ntev ntev.
Txawm hais tias cov kev phom sij no, TetraYdrofuran yog cov khoom lag luam muaj txiaj ntsig zoo. Nws yog feem ntau siv nyob rau hauv kev lag luam kws tshuaj uas yog qhov hnyav rau cov khoom xyaw nquag. Nws tseem yog qhov muaj txiaj ntsig zoo nyob rau hauv kev tsim cov polymers thiab plastics, qhov twg nws ua kom muaj kev tswj hwm kev ua thiab cov khoom kawg.
Ntxiv mus, cov khoom no yog ib qho yooj yim los daws thiab muaj qhov tsis tshua muaj kuab lom. Nws tau pom tias muaj cov tshuaj lom tsawg hauv kev kawm ntawm cov tsiaj, ua rau nws muaj kev nyab xeeb rau kev siv cov txheej txheem tsim kev tsim khoom. Cov khoom no tseem muaj biodegradable, lub ntsiab lus nws tawg rau hauv kev muaj kev phom sij hauv lub sijhawm.
Hauv kev xaus, thaum muaj kev pheej hmoo cuam tshuam nrogTetrahydrofuran, cov kev pheej hmoo no tuaj yeem tswj hwm los ntawm kev tuav cov txheej txheem thiab kev khaws cia. Nrog nws cov kev lag luam ntau thoob plaws hauv ntau qhov kev lag luam thiab nws cov kev lag luam tsawg, TetrahyDrofuran yog cov khoom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo hauv kev ua haujlwm niaj hnub. Tsuav nws siv tau kom raug, tsis muaj laj thawj los xav txog nws cov khoom txaus ntshai.
