Faatonuga:

1. Tetrahydrofuran, o le raw mea o le spandex synthesis, mafai ona polycondensated ia lava (tatalaina tatalaina ma toe polymerization amataina e cation) i poly (tetramethylene ether glycol) (PTMEG), lauiloa foi o tetrahydrofuran polyether. PTMEG ma toluene diisocyanate (TDI) na faʻaaogaina e faia ai ni paʻu faʻapitoa e teteʻe atu ai i le laei, teteʻeina o le suauʻu, lelei maualalo o le vevela o le vevela ma le maualuga o le malosi, ma poloka poli poletito mea faʻaaoga eletise na faia i le dimethyl terephthalate ma le 1,4-butanediol. PTMEG ma molemole mamafa o le 2000 ma p-methylene bis (4-phenyl) diisocyanate (MDI) o loʻo faʻaaogaina o mea masani mo polyurethane uila eletise (spandex fiber), faʻapitoa paʻu ma ni faʻapitoa manaʻoga paluni. O le faʻaaogaina taua o le THF o le gaosia o le PTMEG. E tusa ai ma fua faʻamaumauga fuainumera, sili atu nai lo le 80% o THF i le lalolagi o loʻo faʻaaogaina e maua ai PTMEG, ma PTMEG e tele lava ina faʻaaogaina e gaosia ai filo spandex fiber. 2.Tetrahydrofuran(THF) o se masani masani lelei solvent, aemaise talafeagai mo le faʻamamaina o le PVC, polyvinylidene chloride ma butylamine. E lautele faʻaaogaina o se solvent mo luga ufiufi, anticorrosive ufiufi, lolomi vaitusi, lipine ma ufiufi ufiufi. E mafai ona faʻatonutonuina le mafiafia ma le pupula o le vaega alumini pe a faʻaaogaina i le eletise le faʻamuina ipu plating. Faʻapipiʻi faʻapipiʻi, ufiufi luga o le PVC, faʻamamaina o le reactor o le PVC, aveʻese le ata tifaga a le PVC, ufiufi o le cellophane, vaitusi lolomi palasitika, ufiufi thermoplastic polyurethane, solofanua pipiʻi, lautele faʻaaogaina i luga ufiufi, ufiufi puipuia, vaitusi, soʻosoʻo soʻosoʻo ma gaosia paʻu luga fofo togafitiga.

3. Faʻaaoga e fai ma mea masani mo le tuʻufaʻatasia o meaola pei o vailaʻau mo vailaʻau. I le falemaʻi falemaʻi, e faʻaaogaina e synthesize kebiqing, rifamycin, progesterone ma nisi o fualaʻau vailaʻau. E mafai ona faʻaaogaina o se manogi sui (faʻailo faʻaopopo faʻaopopo) i le suauʻu kesi ma o le autu solvent i falemaʻi alamanuia.

4. chromatographic solvents mo isi faʻaoga (gel permeation chromatography) o loʻo faʻaaogaina mo le kesi natura faʻamaluluina, soli soliʻiga o le acetylene, mea faʻamama moli malamalama, ma isi. manaʻoga mo PTMEG i Saina o loʻo faʻateleina i lea aso ma lea aso, ma o le manaʻoga mo tetrahydrofuran o loʻo faʻaalia foi le televave tuputupu aʻe.

Lapataiga mo le teuina: masani, o oloa e faʻaopopoina i le polymerization inhibitor. Teu i totonu o se fale teu oloa malulu ma ea. Taofi ese mai le afi ma le vevela mafuaʻaga. O le teuina vevela e le tatau ona sili atu i le 30. E tatau ona faʻamau le afifi ae le faʻafesoʻotaʻi ma le ea. E tatau ona teu ese ese mai oxidant, acid, alkali, ma isi pa Faʻamaonia moli ma vaʻalele ea nofoaga na taliaina. E faʻasa ona faʻaaogaina masini masini ma mea faigaluega e faigofie ona gaosi aloiafi. O le nofoaga e teu ai e tatau ona faʻaauupegaina i leakage faʻalavelave faʻafuaseʻi togafitiga masini ma talafeagai teuina mea.

Teuina: 180kg / talipalau.

Malosiaga faʻaletausaga: 2000 tone / tausaga
