Thelekisa i-Hec kunye nezinye ii-thi chu

Iziqwengana zisetyenziswa ngokubanzi kwimveliso yemizi-mveliso, kubandakanya iingubo, izixhobo zokwakha, i-cosmetics, ukutya kunye namayeza. I-Hydroxyyl seluplose (hec) i-tickener ebalulekileyo etsalele ingqalelo kwiipropathi zayo ezizodwa kunye nesicelo ngokubanzi.

1. Ubume kunye noMthombo
I-Hec yi-ether eselfowuni eyenziwe ngokusabela kwi-sellutase yendalo kunye ne-Ethylene oxide. Yi-polymer enganyibilikiyo yamanzi anozinzo lweekhemikhali ezifanelekileyo. Ngokwahlukileyo koko, ezinye izibini zinemithombo eyahlukeneyo, kubandakanya oku kulandelayo:

I-Polysacchaacchaacchaacchaacchaacchaacchaacchaacchariders Suicelide: njenge-XANHAn Gum kunye neGuar Gum, ezi zinto zithathwa zizityalo zendalo okanye ukuvela kwentsholongwane kwaye zikhuselekile kwindalo esingqongileyo.

Izitya zokuqala: ezinjenge-acrylic acid polymers (i-carbomer), ehambelana ngokusekwe kwi-petrochemicals, yindlela yokusebenza ngokuzinzileyo, kodwa imbi yokusebenza.

Iiprotein zokubana: ezinjengeGelatin, zithathwe ikakhulu kwizicubu zezilwanyana kwaye zilungele ukutya kunye namayeza.
I-HEC inolukhuseleko loluntu lokusingqongileyo lwe-selupelose yendalo kunye nokusebenza ngokugqwesileyo kokutshintsha kweekhemikhali ngokwakho, ukufumana ibhalansi phakathi kobuhlobo bokusingqongileyo kunye nokungabi kokutshintsha.

I-2. Ukusebenza okusebenzayo
I-HEC inezi mpawu zilandelayo kwintsebenzo yokuthambisa:

Ukuluka: Hec kunokuchithwa kumanzi abandayo kunye namanzi ashushu ukwenza isisombululo se-viscous esibonakalayo ngereyithi yokutya okhethiweyo. I-XAANHH Hum ihlala ifuna amandla e-Shear ukunceda ukupheliswa, kwaye isisombululo sinokuba ne-turbidity ethile.
Uluhlu lwe-viscofity yohlengahlengiso loLuhlu: Ngokuhlengahlengisa ubunzima bemoyarund kunye nenqanaba lokufakwa endaweni ye-HEC, iimveliso ezinamabanga ahlukeneyo e-viscosity inokufunyanwa ukufezekisa iimfuno ezahlukeneyo zesicelo. Ngokwahlukileyo, uhlengahlengiso lohlengahlengiso lwe-viarity yeGum yeGuaar incinci. Nangona i-acrylic acid polymer inefuthe elihle, inomdla kakhulu kwixabiso le-pH.
I-Shear Intsebenzo ye-Shear Intsebenzo: I-HEC inendlela yokuziphatha ethambileyo kwaye ilungele izihlandlo apho i-viscofity ethile yesakhiwo kufuneka igcinwe. I-Xanthan gum ine-pseudeoplastice kwaye ilungele ukusetyenziswa kwengubo kunye nokutya okutyayo.

3. Uzinzo lwekhemikhali
I-HEC inozinzo oluhle kububanzi be-PH (2-12), kwaye ixhathise ubushushu obuphezulu kunye netyuwa, kwaye ilungele ukusetyenziswa kweenkqubo ezineenkqubo zetyiwa okanye iindawo zobushushu obuphezulu. Ngokumataniswa:

I-Xanthan gum inomsindo ongcono wetyuwa kune-hec, kodwa ihlazo ngokulula phantsi kweemeko ze-Acid kunye neAlkali.
I-Acrylic Polymers inobuthathaka kwi-acid naseAlkali, kwaye inomdla wokusilela phantsi kweemeko eziphezulu zonxibelelwano.
Ukuzinza kwamachiza okutsha kwi-Polysacchadide ephantsi kweqondo lobushushu obuphezulu kunye neemeko ze-oxidages zihlala zingalunganga njenge-HEC.

4. Umahluko kwiindawo zesicelo
I-Poayinti kunye nezinto zokwakha: I-HEC ihlala isetyenziswa kwi-cayishini esekwe emanzini, i-posty powders kunye nokufa, ukubonelela ngeziphumo ezihle zothando kunye neepropathi zokugcina amanzi. I-Xanthan gum isetyenziswe ngakumbi kwizinto eziphantsi kwamanzi, ikakhulu ngenxa yepropathi yayo yokucinga.
I-cosmetics kunye neemveliso zekhemikhali zemihla ngemihla: I-HEC inokubonelela ulusu olugudileyo kunye nefuthe elihle kakhulu, kwaye isetyenziswa ngokubanzi kwimingxunya yobuso kunye ne-outs. I-acrylic polymers inenzuzo kwiimveliso zejeli ngenxa yokungafihli ngokupheleleyo kunye nokuqina okuqinileyo.
Ukutya kunye namayeza: I-Xantan Gum kunye neGuar Gum zisetyenziswe ngakumbi ekutyeni nasekuhlaleni ngenxa yemvelaphi yazo kunye ne-biomatini elungileyo. Nangona i-HC inokusetyenziswa kumalungiselelo okukhululwa ngamachiza, ineendlela ezimbalwa zokutya zokutya.

I-5. Indawo kunye neendleko
I-HEC inobuhlobo obunobuhlobo kwaye ihlawulwe ngenxa yokuba iveliswe ngokusekwe kwiseli yendalo. Inkqubo yemveliso ye-Acrylic Polymers inefuthe elikhulu kwindalo kwaye kunzima ukuthoba imbeko emva kokuchithwa. Nangona i-Xantan Gum kunye neGuar Gum inobuhlobo obusingqongileyo, amaxabiso abo ahlala ephakama ngakumbi kune-HEC, ngakumbi kwiimveliso eziguqulweyo kwizicelo ezichongiweyo.

Njengomntu osebenzayo osebenza ngokusebenza kakuhle, i-HEC inezibonelelo ezizodwa kwiindawo ezininzi. Xa kuthelekiswa ne-XANHAH Gum kunye neGuar Gum, i-HEC ikhuphisa ngokutonga kweekhemikhali kunye nokusebenza kweendleko; Xa kuthelekiswa neepoli ze-Acrylic, i-HEC inobuhlobo ngakumbi kwaye inobubanzi obubanzi. Ekukhetho, izinto ezinjengokusebenza kokuthathwa, uzinzo lwekhemikhali kunye neendleko kufuneka zithathwe ngokuqondakalayo ngokweemfuno ezithile zesicelo ukufezekisa ezona ziphumo zinesiphumo kunye nexabiso.
