Umyalelo:

1. Itetrahydrofuran, izinto ezingafunekiyo ze-spandex synthesis, zinokuzicombulula ngokwazo (ukuvulwa kwendandatho kunye nokuvuselelwa kwepolymerization eqalwe yi-cation) kwi-poly (tetramethylene ether glycol) (PTMEG), ekwabizwa ngokuba yi-tetrahydrofuran polyether. I-PTMEG kunye ne-toluene diisocyanate (TDI) zazisetyenziselwa ukwenza irabha ekhethekileyo ngokuxhathisa ukunxiba, ukumelana neoyile, ukusebenza kakuhle kobushushu obuphantsi kunye namandla aphezulu, kwaye ibhloko le-polyether polyester elastic elastic yenziwe nge-dimethyl terephthalate kunye ne-1,4-butanediol. I-PTMEG enobunzima beemolekyuli zika-2000 kunye ne-p-methylene bis (4-phenyl) diisocyanate (MDI) zisetyenziswa njengezinto ezingafunekiyo ze-polyurethane elastic fiber (i-spandex fiber), irabha ekhethekileyo kunye nezinye izinto ezikhethekileyo. Ukusetyenziswa okuphambili kwe-THF kukuvelisa i-PTMEG. Ngokwezibalo ezinobunzima, ngaphezulu kwe-80% ye-THF emhlabeni isetyenziselwa ukuvelisa i-PTMEG, kwaye i-PTMEG isetyenziselwa ukuvelisa ifayibha ye-spandex elastic. 2.Itetrahydrofuran(I-THF) sisinyibilikisi esiqhelekileyo esifanelekileyo, ngakumbi esifanelekileyo ekunyibilikiseni i-PVC, i-polyvinylidene chloride kunye ne-butylamine. Isetyenziswa ngokubanzi njenge-solvent yokugquma umphezulu, ukutyabeka okuchasayo, inki yokuprinta, iteyiphu kunye nokwaleka kwefilimu. Ingalawula ubukhulu kunye nokuqaqamba koqweqwe lwealuminium xa isetyenziswa kwindawo yokuhlambela i-aluminium engenanto. Tape ukutyabeka, umphezulu ukutyabeka umphezulu, ukucoca i-reactor yePVC, ukususa i-PVC bhanyabhanya, iselifane ukutyabeka, inki yoshicilelo lweplastiki, ityhubhu yeplasma yetyhubhu, isinyibilikisi esincamathelayo, esisetyenziswa ngokubanzi kwindawo yokutyabeka umphezulu, ukhuselo lokhuselo, i-inki, iarhente yokutsala kunye nearhente yonyango yomphezulu wokwenza ulusu.

3. Isetyenziswa njengezinto ezingafunekiyo ze-organic synthesis ezinje ngamayeza. Kushishino lwamayeza, isetyenziselwa ukwenza i-kebiqing, i-rifamycin, iprogesterone kunye nezinye iziyobisi zehomoni. Ingasetyenziselwa njengearhente yevumba (isongezo sokuchonga) kwirhasi yombane kunye nesinyibilikisi esiphambili kushishino lwamayeza.

4. izinyibilikisi ze-chromatographic zezinye izinto ezisetyenziswayo (i-gel permeation chromatography) zisetyenziselwa irhasi yendalo enencasa, izinyibilikisi ze-acetylene extractive, iipolymeric light stabilizers, njl. Ibango le-PTMEG e-China liyanda mihla le, kwaye ibango le-tetrahydrofuran likwabonisa ukukhula okukhawulezayo.

Amanyathelo okhuseleko okugcina: ngokubanzi, iimveliso zongezwa nge-polymerization inhibitor. Gcina kwindawo yokugcina izinto epholileyo kunye nomoya. Gcina kude nomlilo kunye nomthombo wobushushu. Ubushushu bokugcina abugqithi kuma-30 exceed. Iphakheji kufuneka itywinwe kwaye ingadibani nomoya. Kufuneka igcinwe ngokwahlukeneyo kwi-oxidant, i-asidi, i-alkali, njl. Njl. Akuvumelekile ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezilula ukuvelisa iintlantsi. Indawo yokugcina iya kuthi ixhotyiswe ngesixhobo sokuvuza esingxamisekileyo kunye nezinto ezifanelekileyo zokugcina.

Ukupakisha: 180kg / igubu.
