Khoom Description
Tetrahydrofuran (THF) yog cov kua tsis muaj xim thiab tsis muaj zog heev nrog cov tshuaj lom neeg thiab lub cev muaj zog. Raws li ib qho tseem ceeb raw khoom nyob rau hauv cov organic thiab zoo tshuaj industries, nws daim ntawv thov txuas ntxiv mus rau zus tau tej cov polytetramethylene ether glycol (PTMEG) thiab muaj xws li dav siv raws li ib tug hnyav hnyav. Cov cuab yeej no ua rau nws tseem ceeb hauv kev tsim thiab ua cov txheej txheem thiab cov ntaub ntawv luam tawm.

- Tetrahydrofuran (Thf) Formate Structure:
Tetrahydrofuran (Thf) siv
- Tetrahydrofuran (THF) tuaj yeem ua rau cov tshuaj yaj yeeb zoo xws li PVC, polyvinylidene chloride, thiab butaniline, ua rau nws siv dav hauv cov txheej txheem saum npoo, tiv thaiv - cov xim pleev xim, luam ntawv inks, thiab txheej txheem txheej txheej zaj duab xis.
- Hauv kev lag luam tshuaj, THF ua haujlwm ua cov tshuaj tiv thaiv hnyav thiab nruab nrab hauv kev tsim cov tshuaj ntau yam.
- Qhov kev lag luam tseem ceeb ntawm THF yog nyob rau hauv kev tsim cov polytetramethylene ether glycol (PTMEG), uas yog ib qho tseem ceeb hauv kev tsim cov spandex fibers thiab polyurethane cov ntaub ntawv.
