Umyalo:

1. I-Tetrahydrofuran, okokusebenza okuluhlaza kwe-spandex synthesis, kungaba yi-poly polyensensated (ukuvulwa kwezindandatho nokwenziwa kabusha kwe-polymerization kuqalwe yi-cation) ku-poly (tetramethylene ether glycol) (PTMEG), eyaziwa nangokuthi i-tetrahydrofuran polyether. I-PTMEG ne-toluene diisocyanate (TDI) yasetshenziselwa ukwenza injoloba ekhethekile ngokumelana nokugqoka, ukumelana no-oyela, ukusebenza kahle kwezinga lokushisa eliphansi namandla amakhulu, futhi ukuvimba okokunamathisela kwe-polyether polyester kwenziwa nge-dimethyl terephthalate ne-1,4-butanediol. I-PTMEG enesisindo samangqamuzana ka-2000 kanye ne-p-methylene bis (4-phenyl) diisocyanate (MDI) isetshenziswa njengezinto zokusetshenziswa ze-polyurethane fiber (i-spandex fiber), injoloba ekhethekile nokunye okugqokiwe okukhethekile. Ukusetshenziswa okuyinhloko kwe-THF ukukhiqiza i-PTMEG. Ngokwezibalo ezinzima, ngaphezu kwe-80% ye-THF emhlabeni isetshenziselwa ukukhiqiza i-PTMEG, kanti i-PTMEG isetshenziswa kakhulu ukukhiqiza i-spandex fiber fiber. 2.I-Tetrahydrofuran(I-THF) i-solvent ejwayelekile enhle kakhulu, elungele ukuqedwa kwe-PVC, i-polyvinylidene chloride ne-butylamine. Isetshenziswa kakhulu njenge-solvent yokumboza indawo, i-anticorrosive coating, i-inki yokuphrinta, i-tape nefilimu yokumboza. Ingalawula ukushuba nokugqama koqweqwe lwe-aluminium lapho isetshenziswa kubhavu we-aluminium ongenagwele. Tape enamathela, PVC ebusweni enamathela, yokuhlanza PVC ophendulayo, asuse PVC ifilimu, cellophane enamathela, plastic ukuphrinta inki, Thermoplastic polyurethane enamathela, ingcina kuphela, esetshenziswa kabanzi ingubo enamathela, enamathela zokuzivikela, uyinki, isizinda agent kanye zokwenziwa lesikhumba ebusweni ukwelashwa ejenti.

3. Isetshenziswa njengezinto zokusetshenziswa zokwenziwa kwama-organic njengamakhemisi. Emkhakheni wemithi, kusetshenziselwa ukuhlanganisa i-kebiqing, i-rifamycin, i-progesterone nezinye izidakamizwa ze-hormone. Ingasetshenziswa njenge-ejenti yephunga (isithasiselo sokuhlonza) kugesi kaphethiloli kanye ne-solvent enkulu embonini yezemithi.

4. izincibilikisi ze-chromatographic zokunye ukusetshenziswa (i-gel permeation chromatography) isetshenziselwa igesi enamakha enamakha, izinyibilikisi ze-acetylene extractive, ama-polymeric light stabilizers, njll. Ngokusetshenziswa okubanzi kwe-tetrahydrofuran, ikakhulukazi ukukhula okusheshayo kwemboni ye-spandex e-China eminyakeni yamuva, ukufunwa kwe-PTMEG e-China kuyanda usuku nosuku, kanti ukufunwa kwe-tetrahydrofuran nakho kukhombisa ukuthambekela kokukhula okusheshayo.

Ukuqapha kokugcina: imvamisa, imikhiqizo ingezwa nge-polymerization inhibitor. Gcina enqolobaneni epholile futhi enomoya. Hlala kude nomlilo nomthombo wokushisa. Ukushisa kwesitoreji akufanele kudlule u-30 ℃. Iphakheji kufanele ivalwe hhayi ukuxhumana nomoya. Kufanele igcinwe ngokuhlukile kune-oxidant, i-asidi, i-alkali, njll. Izakhiwo zokukhanyisa okuqhumayo kanye nezindawo zokungenisa umoya ziyamukelwa. Akuvunyelwe ukusebenzisa imishini yamathuluzi namathuluzi okulula ukukhiqiza izinhlansi. Indawo yokugcina izofakelwa imishini yokwelashwa okuphuthumayo kanye nezinto zokugcina ezifanele.

Ukupakisha: 180kg / isigubhu.
