Hydroxyyl seluplosesisifo esibalulekileyo sesellulose. Ngenxa yezibonelelo zobutyebi bezinto ezibonakalayo ezinqabileyo, ezihlaziyiweyo, ezihlaziyiweyo, ezingenabutywala, ezingenabunzi, kunye nesivuno esikhulu, uphando kunye nesicelo sitsalele ingqalelo kakhulu. . Ixabiso le-Viscofity yisalathiso sentsebenzo ebaluleke kakhulu ye-hydroxyythl sellyulose. Kweli phepha, i-HydroxyEtheetheetheetheetheetheetheetheetheeth ngexabiso le-viscosity elingaphezulu kwe-5 × 104miparo kunye nexabiso le-ASH kunye ne-ASH PATE-STENCHISIIS YOKUFUNDA NOKUSETYENZISWA KOKUSETYENZISWA KOLWAZI NOKUFUNDA I-AMALUNGISELELO SOKUGQIBELA.
Inkqubo ye-alkali iyoyinkqubo yokulungiselela iAlkali SellUlose. Kweli phepha, iindlela ezimbini ze-alkaliy zisetyenziswa. Indlela yokuqala kukusebenzisa i-acetone njengelila. Isixhobo esiyi-selsulose Stowing siwiswe ngokuthe ngqo ekugxilwe ngokuthe ngqo kwi-sodium ye-sodium hydroxide. Emva kokuba intetho yeXesha leXesha lenziweyo, iarhente ye-estile eyongezwa ngokuthe ngqo iqhuba ngokuthe ngqo indlela yokuphendula. Eyona ndlela yesibini kukuba izinto ezingaselunxwemeni zifakwe kwisisombululo se-SODIim hydroxide kunye ne-Urea, kunye ne-alkali selsulose elungiselelwe ukususa i-eather ngaphambi kokuba i-Etheetisition yeyokuphendula. I-alkali selsulose elungiselelwe ngeendlela ezahlukeneyo ihlalutyelukiswa yi-infrared switcrascopy kunye ne-X-ray. Ngokweepropathi zeemveliso ezilungiselelwe yi-Etheristition, indlela yokhetho igqityiwe.
Ukwenzela ukufumanisa eyona nkqubo ye-synthesi yokufundisa, indlela yokuphendula ye-antioxidant, i-LYE kunye ne-GYE kunye ne-GOCATIC ACCECS kwi-EATICE yokuphendula yahlalutywa kuqala. Emva koko yenza inkqubo yovavanyo yendlela enye yokuphendula, chaza izinto ezinefuthe elinamandla kwintsebenzo ye-hydroxyEseyl ye-hydroxethy, kwaye usebenzise i-viscofity ye-2% yemveliso yemveliso. Iziphumo zovavanyo zibonisa ukuba izinto ezinje ngemali ekhethiweyo ye-ithylene oxide, ixesha lokuphumla, ubushushu kunye nexesha lokuphendula kwesibini zonke zinempembelelo enkulu ekusebenzeni kwemveliso. Isikimu sokuvavanywa kwe-orthogonali esinezinto ezisixhenxe kunye namanqanaba amathathu asondela, kwaye i-culve ijika icinyiwe kwiziphumo ezibonakalayo zinokuhlalutya izinto eziziiprayimari kunye neflethi. Ukwenzela ukulungiselela iimveliso ezinamaxabiso aphezulu obu-viscofity, iqhinga lokuvavanywa eliphelileyo lalinyiselwe, kwaye iskimu esifanelekileyo sokulungiselela i-hydroxythyl seluplose igqitywe kwiziphumo zovavanyo.
Iipropathi ze-viscofity ephezuluhydroxyyl seluplosezahlalutywa kwaye zavavanywa, kubandakanya ukumiselwa kwe-viscofity, umxholo we-ASh, umxholo we-suclear, i-chromared-chtragravic-i-chromared-chneravitic-i-chromadming, iyunifomu ye-nuy, iyunifomu ye-thermografic, i-promormil Isidanga sokufaka endaweni, i-crystallinity, uzinzo lobushushu, njl. Iindlela zokuvavanya zibhekisa kwimigangatho ye-ASTM.
I-HydroxyEtheetheetheetheetheetheetheethl seluplose, i-selsulose ebalulekileyo yeselsulose, itsalele ingqalelo ngenxa yezixhobo zayo ezinqabileyo, ezihlaziyiweyo, ezinokuhlaziywa, ezinokuhlaziywa, ezinokutsha, i-biobgrades, kunye nesivuno esikhulu. Uhlobo lwe-viscosity ye-hydroxyteethyl seluplose ngophawu olubaluleke kakhulu lokusebenza kwayo. I-vickosity ye-hydroxyythyl seluplose ingaphezulu kwe-5 × 104Mparo, kunye nomxholo we-Ash ungaphantsi kwe-0.3%.
Kweli phepha, i-vickosity ye-hydroxyylyl seluplose ilungiselelwe yindlela ye-synthesis ye-synthesis nge-alkalition kunye nesiko. Inkqubo ye-alkali ilungiselelwe i-alkali seluplose. Khetha iindlela ezimbini ze-alkali. Enye yeyokuba izinto zeselsulose zifakwe ngokuthe ngqo nge-acetolo njenge-acetone njenge-icebisi kwi-ACDROIIC ye-ICYDROIIC yeSondo, emva koko iphinde ithathe iarhente yokuphendula. Enye yeyokuba izinto zeselfowuni zifakwe kwisisombululo seSodium yeSodium hydroxide ne-Urea. I-alkali egqithisileyo kwi-alkali selulose kufuneka isuswe ngaphambi kokuphendula. Kweli phepha, iiseli ezahlukeneyo ze-alkali zifundwa ngu-infrared spectroscopy kunye ne-X-ray. Okokugqibela, le ndlela yesibini yamkelwe ngokweepropathi zeemveliso ze-ether.
Ukwenzela ukufumanisa amanyathelo afanelekileyo e-etheriya, indlela yokuphendula ye-Antioxidant, iAlkali kunye ne-Alkali kunye ne-Alkali Acetic kwinkqubo yokutya yafundwa. Izinto ezichaphazela ukulungiswa kwe-hydroxyEsethl yeseluplose igqitywe lulingo olunye. Ngokusekwe kwixabiso le-viscosity yemveliso kwi-2% ye-acteous. Iziphumo zovavanyo zibonisa ukuba ivolumu ye-diucent, ubungakanani be-i-i-e-itholene oxide, ixesha lokuphumla, ubushushu kunye nexesha lokuphinda-phinda nenqanaba lesibini linempembelelo enkulu kwimveliso yemveliso. Indlela yezifundo ezisixhenxe kunye namanqanaba amathathu ayamkelwa ukujonga eyona ndlela iphambili yokulungiselela.
Sihlalutya iipropathi zezinto ezilungiselelwehydroxyyl seluplose, kubandakanya i-viscofity, i-ash, ukuhambisa ukukhanya, ukufuma, njl. Isimo se-humbuner, i-chuflere ye-humbune, i-chromaily, i-chromaillity, i-DSC kunye neendlela zokuvavanya zamkela imigangatho ye-istm.
