Tus nqi ntawm thf tsis yog lus; Nws nyob hauv nws lub luag haujlwm dua li cov kuab tshuaj thiab cov khoom siv tshuaj lom neeg.
1. Daim ntawv thov raws li 'top -} qib hnyav':
Kev tsim cov polyurethane elastic evasce (spandex): qhov no yog kev siv ntau tshaj plaws ntawm cov neeg thf. Lycra ® thiab lwm cov spandex fibers muaj nyob rau hauv cov kis las, ua luam dej, peb hnav txhua hnub (tetrearch ether) glycol, ib tug tseem ceeb khoom siv polymerized los ntawm thf. Qhov kev loj hlob ruaj khov ntawm lub ntiaj teb textile thiab cov khoom lag luam ncaj qha drives qhov kev thov ntawm high- zoo thf.
Cov tshuaj tiv thaiv cov tshuaj tiv thaiv rau PVC thiab lwm yam khoom siv polyvinyl thiab lwm yam khoom siv hluav taws xob, cov khoom lag luam, tshwj xeeb, tshwj xeeb yog tsim nyog rau cov xwm txheej ziab lossis muaj zog nplaum rau cov ntaub ntawv tshwj xeeb.
Cov kev cuam tshuam thoob ntiaj teb: Hauv ntau cov tshuaj synthic: cov tshuaj lom neeg muaj zog, thiab kev lag luam hydrogenized, thiab kev lag luam kev lag luam zoo nkauj thiab cov khoom siv hluav taws xob zoo nkauj thiab cov tshuaj ruaj khov.
2. Daim ntawv thov raws li qhov tseem ceeb rau cov khoom siv rank tshuaj lom neeg:
Synthesis ntawm Polytetramethylene Ethers Glycol: Qhov no yog qhov tseem ceeb derivative txoj kev ntawm THF, thaum kawg ua haujlwm rau cov chaw ua lag luam spandex loj.
Kws Tshuaj Kho Mob: Thf yog qhov nruab nrab tseem ceeb nyob rau hauv synthesis ntawm ntau cov moleculical molecules, xws li cov tshuaj hormones thiab tshuaj tua kab mob thiab tshuaj tua kab mob. Nws daim ntawv thov nyob rau hauv lub chaw muag tshuaj yuav tsum muaj cov qauv kev siab heev, feem ntau tsim nyog 'portacineecectical {}-}} kev purity khoom.
Lwm yam tshuaj lom neeg: Thf kuj tseem siv tau los tsim cov khoom lag luam siab ntawm - tus nqi chemical xws li tetrahydrotiols thiab 1,4-butanediol.
Kev nkag siab mus rau hauv kev lag luam lag luam txawv teb chaws: Cov Sijhawm thiab Cov Sib Tw
Rau cov lag luam rau hauv cov khoom lag luam tawm txawv teb chaws ntawm cov khoom lag luam tshuaj lom neeg: nrog cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov khoom lag luam ruaj khov rau cov khoom siv ua ntej yog qhov dav.
Cov Kev Tsim Nyog High rau cov khoom siv txuas ntxiv thiab cov khoom siv 3 ya mus rau cov kev tsim txom cov khoom lag luam thiab kev thauj mus los (kev lag luam thoob ntiaj teb) Nov yog qhov uas yuav tsum tau muab qhov tseem ceeb hauv kev lag luam tawm txawv teb chaws.
Cov qhab nia zoo me me: Kev ua lag luam muaj cov kev faib tawm meej rau cov ntawv nyeem, xws li qib kev lag luam / hluav taws xob. Siab -}}} Cov khoom lag luam muaj txiaj ntsig ntau dua cov neeg muaj peev xwm ntau tus qauv hauv cov thev naus laus zis thiab kev tswj hwm zoo.
Kev tiv thaiv ib puag ncig thiab kev txhim kho kev loj hlob: nrog cov txheej txheem ib puag ncig ntawm 1,4-butanol ua cov mainstream) thiab cov thev naus laus zis ua dua tshiab tau txais ntau zuj zus. Lub puab tsaig ntsuab thiab muaj kev nyab tsa yuav dhau los ua kev sib tw tom ntej zoo.
Tetrahydrofuran (THF) yog deb tshaj li qhov kev siv tshuaj yooj yim yooj yim; Nws yog tus choj tseem ceeb txuas txuas rau kev lag luam tshuaj yooj yim thiab kev ua siab siab-}}}}}}}}}}}}}}}}}}}}}}}}}}} kawg tsim. Los ntawm spandex, uas ua rau cov khaub ncaws zoo dua thiab ywj siab, cov khoom siv rau kev noj qab haus huv, thiab ua haujlwm rau cov khoom siv thoob ntiaj teb thiab ua lag luam polymers, kws tshuaj, thiab lub zog tshiab.
