Uyini umehluko phakathi kwe-xanthan gum ne-HEC?

I-Xanthan gum kanye ne-Hydroxyethyl cellulose (HEC) womabili ama-hydrocolloid asetshenziswa kakhulu ezimbonini ezahlukahlukene, ikakhulukazi ekudleni, kwezokwelapha, nakwimikhiqizo yokunakekela umuntu. Ngaphandle kokufana okuthile ekusetshenzisweni kwazo, ahlukile ngokuya ngesakhiwo sawo samakhemikhali, izakhiwo, nokusebenza kwawo.

1.Isakhiwo Sekhemikhali:

I-Xanthan gum: I-polysaccharide etholakala ekuvubeleni kwama-carbohydrate, ikakhulukazi i-glucose, yi-bacterium i-Xanthomonas campestris. Iqukethe umgogodla wezinsalela ze-glucose namaketanga aseceleni amayunithi aphindayo we-trisaccharide, okuhlanganisa i-mannose, i-glucuronic acid, ne-glucose.

I-HEC: I-Hydroxyethyl cellulose iyi-ether engeyona ionic cellulose etholakala ku-cellulose, i-polysaccharide eyenzeka ngokwemvelo etholakala ezindongeni zamaseli ezitshalo. I-HEC iguqulwa ngokwethula amaqembu e-hydroxyethyl kumgogodla we-cellulose.

2.Ukunyibilika:

I-Xanthan gum: Ibonisa ukuncibilika okuphezulu emanzini abandayo nashisayo. Yakha izixazululo ze-viscous kakhulu ngisho nasezintweni eziphansi.

I-HEC: I-Hydroxyethyl cellulose iyancibilika emanzini, futhi ukuncibilika kwayo kungahluka kuye ngezinga lokushintsha (DS) lamaqembu e-hydroxyethyl. I-DS ephezulu ngokuvamile iphumela ekuncibilikeni okungcono.

3.I-Viscosity:

I-Xanthan gum: Iyaziwa ngezakhiwo zayo zokujiya ezingavamile. Ngisho nasezindaweni eziphansi, i-xanthan gum ingakhuphula kakhulu i-viscosity yezixazululo.

I-HEC: I-viscosity yezixazululo ze-HEC nayo incike ezintweni ezifana nokugxilisa ingqondo, izinga lokushisa, kanye nezinga le-shear. Ngokuvamile, i-HEC ibonisa izakhiwo ezinhle zokuqina, kodwa i-viscosity yayo iphansi uma iqhathaniswa ne-xanthan gum ekugxilweni okulinganayo.

4.Ukuziphatha Kokugunda:

I-Xanthan gum: Izixazululo ze-xanthan gum ngokuvamile zibonisa ukuziphatha kokunciphisa i-shear, okusho ukuthi i-viscosity yazo iyancipha ngaphansi kwengcindezi ye-shear futhi iyalulama uma ingcindezi isisusiwe.

I-HEC: Ngokufanayo, izixazululo ze-HEC ziphinde zibonise ukuziphatha kokunciphisa i-shear, nakuba ububanzi bungase buhluke kuye ngebanga elithile nezimo zesixazululo.

5.Ukuhambisana:

I-Xanthan gum: Ihambisana nohlu olubanzi lwama-hydrocolloid kanye nezithako ezivame ukusetshenziswa ekwakhiweni kokudla nokunakekelwa komuntu siqu. Ingakwazi futhi ukuzinzisa ama-emulsions.

I-HEC: I-Hydroxyethyl cellulose iphinde ihambisane nezithako ezihlukahlukene futhi ingasetshenziswa ngokuhambisana nezinye iziqinisi kanye neziqinisi ukuze kuzuzwe izici ezifiselekayo ze-rheological.

6.I-Synergy namanye ama-Thickeners:

I-Xanthan gum: Ibonisa imiphumela ye-synergistic uma ihlanganiswe namanye ama-hydrocolloid afana ne-guar gum noma i-locust bean gum, okuholela ekuthuthukisweni kwe-viscosity nokuzinza.

I-HEC: Ngokufanayo, i-HEC ingasebenzisana namanye ama-thickeners nama-polymers, inikeze ukuguquguquka ekukhiqizeni imikhiqizo enezidingo ezithile zokuthungwa nokusebenza.

7.Izindawo zokufaka isicelo:

I-Xanthan gum: Ithola ukusetshenziswa okubanzi emikhiqizweni yokudla (isb, amasoso, okokugqoka, imikhiqizo yobisi), imikhiqizo yokunakekelwa komuntu siqu (isb., amafutha okugcoba, okhilimu, umuthi wokuxubha), kanye nemikhiqizo yezimboni (isb, uketshezi lokumba, opende).

I-HEC: I-Hydroxyethyl cellulose ivame ukusetshenziswa emikhiqizweni yokunakekela umuntu (isb, ama-shampoos, ukugeza umzimba, okhilimu), imithi (isb, izixazululo ze-ophthalmic, ukumiswa komlomo), kanye nezinto zokwakha (isb, amapende, izinto zokunamathisela).

8.Izindleko Nokutholakala:

I-Xanthan gum: Ivamise ukubiza kakhulu uma iqhathaniswa ne-HEC, ngokuyinhloko ngenxa yenqubo yokuvutshelwa ehilelekile ekukhiqizeni kwayo. Nokho, ukusetshenziswa kwayo okusabalele nokutholakala kwayo kunomthelela ekuhlinzekeni kwayo ezimakethe uma kuqhathaniswa.

I-HEC: I-Hydroxyethyl cellulose ibiza kakhulu uma iqhathaniswa ne-xanthan gum. Ikhiqizwa kabanzi ngokuguqulwa kwamakhemikhali e-cellulose, eningi ngokwemvelo.

kuyilapho i-xanthan gum ne-HEC babelana ngokufana okuthile ekusetshenzisweni kwabo njengama-hydrocolloid, babonisa umehluko ohlukile ngokuya ngezakhiwo zabo zamakhemikhali, ukuncibilika, i-viscosity, ukuziphatha kwe-shear-thinning, ukuhambisana, ukusebenzisana namanye ama-thickeners, izindawo zokufaka isicelo, kanye nezindleko. Ukuqonda lo mehluko kubalulekile ukuze abaklami bakhethe i-hydrocolloid efaneleke kakhulu yokwakheka komkhiqizo othile nezici zokusebenza ezifiselekayo.
