I-Hydrophobic eguqulweyo ye-Hydroxyythyl seluplose (hec) luhlobo olufunyenweyo ngokwazisa amaqela e-hydrophobic (efana ne-chain ende-ialkyl, amaqela anombala omnandi, njl. Njl. Olu hlobo lwezinto ezihlanganisiweyo luhlanganisa iipropathi ze-hydrophilic ze-hydroxyteethy ngepropathi ye-hydrophobic yamaqela e-hydrophobic kwaye isetyenziswa ngokubanzi kwi-carrings, izityholo, i-cosmetics kunye nabathwali iziyobisi.
I-1. Indlela ye-Synthesis ye-hydrophofyl ye-hydroxyythl
I-synthesis ye-hydrophothyl ye-hydrophoethyl seluplose idla ngokuqhutywa kwezi ndlela zilandelayo:
1.1 Ukuphendula okuqinisekileyo
Le ndlela kukuphendula i-hydroxyteethyl selupesse ye-headgevers yekhemikhali (ezinje nge-chain ye-acid, i-chidty acid, njl. Njl.) Ukwazisa iimolekyuli zeselcerical. Ukuphendula okuphezulu akunakwazisa ngempumelelo amaqela e-hydrophobic, kodwa uhlengahlengise i-hydrophobizetion kunye nefutha ye-trongsmers. Iimeko ezisabela kwinkqubo ye-synthesi, ezinjengamaqondo obushushu, ixesha, ukusombulula i-sponth kunye ne-catalyst, kuya kuchaphazela ukusebenza kwemveliso yokugqibela.
1.2 Ukuphendula okukhoyo
Kule ndlela, iqela le-hydroxyl ye-hydroxythyl seluplose itshintshwe yiqela le-hydrophobic (njenge-alkyl, phenyl, njl.). Inzuzo yale ndlela kukuba iimeko zeSynthesis zinobulali, iimpawu zendlela ye-hydroxytethl selliese zinokugcinwa kakuhle, kwaye imveliso eguqulweyo idla ngokufumana isiphumo esihle kunye nefuthe elihle.
1.3 Impendulo yeCopolymerization
Ngokucokiseka ngolunye uhlobo lwe-monomers (njenge-acrylic acid, i-acrylate, njl.), I-polymer entsha ene-hydrophotity inokulungiswa. Le ndlela inokufikelela kulawulo oluchanekileyo lokusebenza okukhulu kweselutase ngokuhlengahlengisa umlinganiso wezilwanyana ezahlukeneyo.
1.4 Indlela yokuThengisa
I-hydrophobic idityaniswe ngamachiza afakwe kwimichiza ye-Hydroxythyl sellyAse ukwenza iibhloko ze-hydrophobic okanye iziqendu. Le ndlela inokuphucula uzinzo lwe-shirm kunye nomsebenzi womphezulu we-hydrophothyl ye-hydrophothyl sellulose, elungele iimfuno ezithile zomsebenzi ophezulu.
I-2. Umatshini wokuqina kwe-hydrophobiethyl ye-hydroxyyethyl seluplose
Indlela yokuthambisa ye-hydrophobiethyl ye-hydroxyEseyl yeseluplose inale miba ilandelayo:
2.1 Ukunyusa uxinzelelo lwe-Intermolecular
Ukuqaliswa kwamaqela e-hydrophobic kuphucula unxibelelwano phakathi kweemolekyuli zeselfowuni, ngakumbi kwindawo ye-ACDROphobic, apho amaqela e-hydrophobic edla ngokudibanisa kunye ukwenza i-agergate amakhulu emolekyuli. Esi siphumo sokukhulisa isiphumo sokukhokelela ekunyukeni kwesisombululo, ngaloo ndlela sibonisa ipropathi eyomeleleyo.
2.2 Unxibelelwano lwe-hydrophilic-hydrophobic
Amaqela e-hydrophilic (anjenge-hydroxyytethl) kunye namaqela e-hydrophobic (njenge-alkyl, phenyl, njl.) Kwi-hydrophothyl ye-hydrophose eshiyiweyo. Kwinqanaba le-ACDROphilic icandelo lisebenzisana ngokungqongqo kunye neemolekyuli zamanzi, ngelixa i-hydrophobic yenxalenye inomtsalane kwi-hydrophobic, ngakumbi ukwandisa ukuxinana kwe-hydrophobic, ngakumbi ukunyusa i-molecusty.
2.3 ukwakha ubume benethiwekhi yesisombululo
Emva kokulungiswa kwe-hydrophobic, ubume be-molecular cain inokutshintsha, yenze ubume benethiwekhi eqinileyo. Ulwakhiwo lwenethiwekhi lunokuphucula kakhulu i-viccoecity kunye nesakhono sokuthathwa kwesisombululo ngokudibanisa umnqamlezo phakathi kweemolekyuli.
2.4 Kulula ukwenza i-gel-njengesakhiwo esifana nejeli
Ngenxa yokuqaliswa kwamaqela e-hydrophobic, i-hydrophobiethyl ye-hydrophothyl seluplose ineepropathi ezihle kakhulu. Phantsi kweemeko ezifanelekileyo, ezinje ngotshintsho kubushushu, i-pH okanye uxinzelelo, amaqela alungisiweyo e-Hydrophobic kunokubangela ukwakhiwa kwezakhiwo zejeli kwisisombululo esibengezelayo.
3. Ukusetyenziswa kwe-hydroxyythl ye-hydroxyythl seluplose
I-Hydrophobic eguqulweyo ye-HydroxyEtheetheethyl isetyenziswe kwiindawo ezininzi zeshishini, ngakumbi kwiimeko apho kuqalwa khona, ukuphuculwa kwenkululeko kunye nophuculo lokuzinza luyafuneka:
3.1 I-Coayings kunye neepeyinti
Kwishishini lezixhobo, i-Hydrophobiethyl i-hydroxyyl ye-hydrophothyl seluplose inokuphucula iipropathi zeRheolophu, ukunqunyanyiswa kunye nokusebenza kokwakhiwa kwengqumbo, ngelixa iphucula ukunyangwa kwamanzi kunye nokuchasana nebala.
3.2 Iicoci kunye neendlela zokucoca
Ukongeza i-Hydrophobiethyl ye-hydrophoethyl ye-hydrophosethyl ukuya kwi-Cociloed ukuya kwisicoci kunokuphucula i-viscomosity yesicoci, esenza sizinze ngakumbi kwaye kulula ukulawula ngexesha lokusetyenziswa.
3.3 cosmetics
Kwintsimi ye-cosmetics, i-hydrophobiethyl ye-hydrophothyl seluplose idla ngokusetyenziswa njenge-tickener kunye nearhente, ngakumbi kwi-lote, enokuphucula imveliso kunye neemvakalelo zemveliso.
3.4 Umthwalo weziyobisi
Ngenxa yokuhlelwa kwayo kwaye i-biomatises ye-biomativey ye-Hydrophothyl ye-hydrophothyl ye-hydroclosethy ifundwe ngokubanzi ukuze isetyenziswe kwiinkqubo zokuthumela ezilawulwa ngamachiza, ezinokulawula ngokufanelekileyo iziyobisi.
Ngokwazisa amaqela e-hydrophobic, i-hydrophothyl ye-hydrophothyl seluplose ayinikanga kuphela i-hydroxyyl yeyokwenyani, kodwa iyenza ibonise intsebenziswano egqwesileyo kwizicelo ezahlukeneyo. Indlela yayo yokuqaqamba ikakhulu ixhomekeke kwintsebenzo phakathi kwamaqela e-hydrophobic kunye namaqela e-hydrophilic, iziphumo zokudibanisa iimolekyuli kunye notshintsho kubume besisombululo. Ngokwenza nzulu kophando, indlela ye-synthesis kunye nendawo yokwenza isicelo se-hydrophothyl ye-hydrophoethy ye-hydroxythy iya kwandiswa ngakumbi, ngamathemba amanzi entengiso.
