IHydroxypropyl Methylcellulose (HPMC)yipolymer enyibilikayo emanzini ephuma kwi-cellulose, i-biopolymer yendalo.I-AnxinCel®I-HPMC isetyenziswa kakhulu kushishino lolwakhiwo, ngakumbi kudaka kunye nolwakhiwo lodaka. Indima yayo ephambili kwezi zicelo kukuphucula iipropati zokugcina amanzi zodaka, okuyimfuneko ekufezekiseni ukusebenza kakuhle ngexesha lokudibanisa kunye neenkqubo zokusebenzisa.
Indima yoGcino lwaManzi kuMdaka
Ukugcinwa kwamanzi kumdaka kubhekiselele ekukwazini komxube ukugcina amanzi emva kokuba isetyenziswe kumphezulu, ukuvumela ukuba ihlale isebenza kwaye ifakwe emanzini ngexesha lokumisela kunye nenkqubo yokunyanga. Ukugcinwa kwamanzi okufanelekileyo kuqinisekisa ukuba umdaka unokwenza ibhondi eqinile kunye ne-substrate kwaye ithintele imiba enjengokuqhekeka, ukuncipha, okanye ukubambelela kakubi. Ukugcinwa kwamanzi okungonelanga kunokubangela ukunyanga okungalinganiyo, okukhokelela kumalungu odaka olubuthathaka, ukunciphisa amandla okubopha, okanye ukuqina kwangaphambi kwexesha.
Ukugcinwa kwamanzi kubaluleke kakhulu kwimixube eyomileyo, eyimixube epakishwe kwangaphambili yesamente, isanti, kunye nezongezo. Xa ixutywe namanzi kwindawo yomsebenzi, ezi zixhobo zodaka kufuneka zigcine isixa esaneleyo sokufuma ukuze kuqinisekiswe ukumanzisa okwaneleyo kwamasuntswana esamente, ngaloo ndlela kuzuze amandla apheleleyo kunye nokuqina. Kulo mxholo, i-HPMC idlala indima ebalulekileyo ekulawuleni ukugcinwa kwamanzi kunye nokuphucula ukusebenza kunye nokusebenza kodaka.
Njani i-HPMC yokuphucula ukugcinwa kwamanzi odaka
Ukunyibilika kwamanzi kunye neGel Formation: I-HPMC yipolymer enyibilikayo emanzini eyenza i-gel-efana nesakhiwo xa ixutywe namanzi. Esi sakhiwo sejeli sinokufaka iimolekyuli zamanzi kunye nokunciphisa ukuvela komphunga, ngaloo ndlela ukwandisa umthamo wokugcina amanzi wodaka. I-gel ikhusela udaka ukuba lome ngokukhawuleza, lugcine izinga elifanelekileyo lokufuma ngexesha lokunyanga.
Ulawulo lweViscosity: I-viscosity yomxube wodaka iphenjelelwa kubukho be-HPMC, enceda ekuzinziseni umxube. Ngokwandisa i-viscosity, i-HPMC iqinisekisa ukuba amanzi asasazwa ngokulinganayo kuwo wonke umxube kwaye inceda ukuthintela ukuhlukana kwamanzi kunye neengqungquthela eziqinileyo. Le viscosity ilawulwayo ayiphuculi nje kuphela ukugcinwa kwamanzi odaka kodwa iphucula ukusebenza kwayo, okwenza kube lula ukuyifaka kunye nokusasazeka.
Ukuthintelwa kokuqina kwangaphambi kwexesha: Ngethuba lokusetyenziswa komdaka, ukuqina kwangaphambi kwexesha kunokwenzeka ngenxa yokulahleka kwamanzi ngokukhawuleza. I-HPMC inceda ukucothisa le nkqubo ngokusebenza njenge-arhente yokugcina amanzi. Oku kuqinisekisa ukuba udaka luhlala lufumile ixesha elide, luvumela ukunamathela okungcono kwiindawo kunye nokuthintela iintanda ezinokuthi zenze ngenxa yokungalingani kwe-hydration.
Ukuphuculwa kokuncamathela: Njengoko i-HPMC iphucula ukugcinwa kwamanzi, iqinisekisa ukuba kukho inqanaba elihambelanayo lokufuma kwi-particle ye-cement ukuze i-hydrated ngokufanelekileyo kunye ne-bond kunye ne-aggregates. Olu phuculo lwe-hydration luphumela kwibhondi eyomeleleyo phakathi kodaka kunye ne-substrate, ukuphucula ukubambelela kunye nokusebenza ngokubanzi. Kuluncedo ngakumbi xa usebenza ngezinto ezirhabaxa, ezifana nezitena okanye ikhonkrithi, ezidla ngokufunxa ukufuma ngokukhawuleza.
