Zithini izithako ze-hydroxythyl sellise?

I-HydroxyEtheetheetheetheetheetheethl seluplose (hec) i-polymer ebalulekileyo ye-polymer ye-polymer yeklasi ye-selsulose ye-Etem Sether ye-SWETE. Ifunyanwa yi-Etheristic Rection ye-SellUlose yeNdalo kunye ne-EOLYCYAS ONESIA (E-E-Etholene oxide) phantsi kweemeko ze-Alkaline. I-HydroxyEtheetheetheetheetheetheethl seluplose ngumgca we-Polysaccharacchaaccharide equlunqwe nge-Glucose Unit kwiCandelo leeShemikhali, kwaye onke amaqela e-hlucose athatyathwa ngamaqela e-hldroxyyl ukuya kwi-hydroxyEse.

Izithako kunye nendlela yemichiza
Ubume bemolekyuli ye-hydroxythy yeselutase ubukhulu becala ibandakanya la macandelo alandelayo:

I-SellUlose Putbone: I-SellUlose yindalo yendalo, eyona nto iphambili kuyo i-chain ye-Glucose ye-Glucose ixhunyiwe yi-β-1,4-Glycosidic Bonds. Olu lwakhiwo lwe-selulose inika i-crystallies ephezulu kunye namandla omzimba.

I-HYDROXYETETHERT: Kwiyunithi ye-Glucose ye-Selebose Tlebose, kukho amaqela amathathu e-hydroxyl (efumaneka kwi-C2, C3 kunye ne-C3 ngezikhundla ngendlela efanelekileyo. I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheethl iveliswa ngokwazisa amaqela e-hydroxyl ngeqela le-endroxyl nge-Eyerroxyl kunye ne-Egylene oxide. Ukuqaliswa kwezi zinto zihlekisayo kunciphisa i-crystallity ye-sellyulose, kuphucula ukubenzela amanzi, kwaye kwenza ukuba ibonise i-bickeling elungileyo kunye ne-viscoelity kwisisombululo esinamandla.

Ubunzima bemolekyuli kunye nenqanaba lokufakwa endaweni: Ubunzima bemoyarund kunye nenqanaba lokufaka endaweni (okt, inani lamaqela e-hydroxyl Ngokubanzi, i-hydroxythyl seluplose ye-molecular inobunzima obungcono kunye nobuchule bokuthathwa, ngelixa inqanaba eliphezulu lokufaka endaweni yomelele kunye nozinzo.

Iipropathi zeSteyishini ze-hydroxyythl seluplose
Ngenxa yobume bayo obukhethekileyo, i-hydroxyyl seluplose ibonisa uthotho lweepropathi ezigqwesileyo ezigqwesileyo:

I-Solubang Water: I-Hydroxythyl Selelose inyibilika ngokulula nawo amanzi abandayo kwaye ashushu ukwenza isisombululo esicacileyo okanye esincinci se-colofal. Inkqubo yayo yokuchithwa ayichaphazelekanga kakhulu kwixabiso le-pH kwaye ihlala izinzile ngaphezulu kwe-PH ye-PH (ihlala phakathi kwe-2 ne-12).

Ukutyibilika: I-HydroxyEtheetheetheetheetheetheetheetheethy inefuthe elihle kakhulu kwisisombululo samanzi, kwaye ubuchule bayo bokuthathwa buchaphazelekile bubunzima bemolekyuli, isidanga sokufaka endaweni kunye nesisombululo. Njengoko uxinzelelo luyenyuka, uVekyuli wesicombululo unyusa ngokungaphezulu, ngoko ke isetyenziswa ngokubanzi kwimizi-mveliso efuna i-thickers.

Umsebenzi womphezulu: Kuba i-hydroxyythl seluplose ineemolekyuli ze-hydrophilic kunye namathambo e-hydrophobic, inokunciphisa uxinzelelo lwamanzi kwisisombululo kwaye ubonise umsebenzi othile. Le propati yenza ukuba isetyenziswe kwiingubo, ii-inks kunye namanye amasimi, kwaye zinokuphucula ulwelo kunye neepropathi ezikhuphayo zemveliso.

Uzinzo: I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheeth inozinzo oluhle kwisisombululo samanzi, inokumelana nefuthe lee-oxidants gadalala kunye nokukhanya, kwaye lizinzile phantsi kweemeko ze-asiid kunye ne-alkaline. Ayiyi kuncitshiswa ngeyonakalisa uninzi lwe-microorganisms kwisisombululo esinamandla, ke akukho lula ukonakala ngexesha lokugcina.

I-biomitiatiby kunye nokhuseleko: I-HydroxyEtheetheetheethl isetyenziswe ngokubanzi kukutya, i-cosmetics kunye neyeza kuba ivela kwi-selsulose yendalo kwaye igcina ityhefu elungileyo kunye netyhefu ephantsi emva kokulungiswa kweekhemikhali. Umzekelo, isetyenziswa njenge-thi cokeener kwaye i-sticker ekutyeni, njenge-hipticant kunye ne-emulsifier ye-hillsifier kwi-cosmetics, kwaye njenge-Binder kunye ne-therix elawulwayo yamacwecwe kumacwecwe amachiza amayeza.

Ukulungiselela kunye nokuSebenza
Ukulungiswa kwe-hydroxythyl seluplose idla ngokubahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlulahlula-lungiselelo kwe-seluplose kudla ngokwahlukeneyo: i-alkalition ye-seluplose, i-ethe thetheriting yokuphendula, ukucocwa kunye nokumohlwaya. Okokuqala, i-sellyulse inyangwa phantsi kweemeko ze-alkaline ukwenza amaqela e-hydroxyl yeselutase, emva koko aphendule kwi-Ethylene oxide ukuba ivelise i-hydroxyyl. Okokugqibela, imveliso yokugqibela ifunyanwa ngamanyathelo anjengelinye ilizwe, ukucocwa kunye nokomisa.

I-HydroxyEtheetheetheetheetheetheethy isetyenziswe ngokubanzi kwizinto zokwakha (ezinjengokufa kwesamente), iikhemikhali zemihla ngemihla (ezinje ngeenkqubo zokuthumela ezilawulwa ngamachiza) kunye nemveliso yokutya (njengamanzi).

I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheethy isetyenziswe ngokubanzi kwimimandla eyahlukeneyo ngenxa yezinto zayo ezibalaseleyo zomzimba kunye neekhemikhali kunye nokuqalisa. Ukwahluka kwesiseko sayo kunye nokuqulunqwa kuyabenza ukuba bakwazi ukudlala indima ebalulekileyo ekuthambeni, ukumiswa, ukumiswa, ukuqulunqwa kwefilimu kunye nokuzinza kweekhemikhali ezibalulekileyo.
