I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-selsulose esetyenziswa ngamanzi asetyenziswa ngamanzi asetyenziswa ngokubanzi kumiswaniso. Uzinzo lokumiswa lubhekisa kubuchule bamasuntswana aqinileyo ukuba bahlale besasazeke ngendlela engafakwanga kangangexesha elide ngaphandle kwe-sediment okanye i-agegreration. Iipropathi ezizodwa zomzimba kunye neekhemikhali ze-HPMC zenza ukuba idlale indima ebalulekileyo ekuphuculeni uzinzo lokunqunyanyiswa.
Iipropati ezisisiseko ze-HPMC
Ipropathi yomzimba kunye neekhemikhali
I-HPMC yindawo efunyaniswayo efunyanwa yi-methyyration yenxalenye yeThutyuli ye-sellyulose. Isakhiwo sayo semolekyuli siqukethe i-hydroxyl i-hydroxyl (-------------hic) ye-hydrophobic (-och₃) kunye namaqela e-hydroxypropy, eyenza inyibiliki ye-hydroxlypropy, eyenza ukuba inyibilike ibe ngamanzi kwaye isebenza ngamanzi kwaye isebenza ngamanzi. I-HPMC inokwenza isisombululo se-viscous emanzini, kwaye utshintsho lwayo lokunxibelelana noxinzelelo, ubushushu kunye nePH.
Iipropathi ze-Viscosity
Isisombululo se-HPMC sibonisa iipropathi ze-fluid engatshayo, kwaye ukubonwa kwayo kuncipha ngokukhulisa ireyithi yoomasipala, oko kukuthi, ibonisa iipropathi zehear. Le ndawo inefuthe elibalulekileyo ekuzinzisweni kwengqolowa kokunqunyanyiswa kuba inokubonelela nge-viscofity efanelekileyo ukuthintela i-sedation yamasuntswana ngelixa ichukumisa okanye igaleleka.
Indlela yokufumana ifuthe le-HPMC kwi-STATE YOSHINO
I-1. Iziphumo zokonwaba
Iziphumo zokuqaqamba kwe-HPMC kukuncama i-sediment yamasuntswana aqinileyo ngokwandisa i-viscofity yokumiswa. Iziphumo ezinkulu ziboniswa ikakhulu kwezi zinto zilandelayo:
Ukonyusa i-viscofity yendawo: i-HPMC inokunyusa kakhulu i-viscofity yokumiswa, ngaloo ndlela kuncitshiswa iqondo lokuhamba kwamasuntswana aqinileyo kulwelo. Kungenxa yokuba umthetho kaStokes, inqanaba le-sedition lamasuntswana lilingane ngokulinganayo kwi-viscomosity yendawo. Ukunyuka kwe-viscofity kunokuthoba i-sedation yamasuntswana kunye nokonyusa uzinzo lokumiswa.
Ukwenza ubume benethiwekhi emithathu: I-HPMC inokwenza ubume benethiwekhi-njengenethiwekhi emanzini, enokuthi ifake kwaye ilungelelanise amasuntswana aqinileyo kwaye ubathintele ekusombululeni. Olu lwakhiwo lwenethiwekhi lugcinwa ziibhondi ze-hydrogen kunye nokusebenzisana kwe-hydrophobic, ukugcina amasuntswana asasazeke ngendlela efanayo.
I-2. Isiphumo se-elektrostatic
Isakhiwo se-geculari se-HPMC siphethe intlawulo ethile (umz. Ngokulungelelanisa amandla omphezulu wamasuntswana, i-HPMC inokunyusa ukubuyiselwa kwe-elektrostiki phakathi kwamasuntswana, ngaloo ndlela kuthintela ukwahlula-hlula kunye nokusetyenziswa kwamasuntswana.
Intlawulo yokuhlawula: Isityholo se-HPMC sinokutshintsha ukuxinana kwamasuntswana, ukwandisa ukubuyiselwa kwe-elektrostiki phakathi kwamasuntswana, kwaye kucothise utyekelo lwamasuntswana kwi-Aggregate.
Ukuzinzisa iinkqubo zeColoday: kwiinkqubo ezithile zeColoday, i-HPMC inokunceda uzinze iziqwengana ze-colloidal zisasazekile kwaye zithintele ekuhlaseleni ngenxa yemikhosi yeVer okanye eminye imikhosi enomdla.
I-3. Isiphumo sokuthintela
Iimolekyuli ze-HPMC zinokwenza ingqumbo yesithintelo kwisithintelo ekumiswe, enokuthintela ngokwasemzimbeni kunye nokudityaniswa phakathi kwamasuntswana, ngaloo ndlela kunyusa ukuzimela.
Isithintelo seSpatial: Iimolekyuli ze-HPMC zenza ungqimba lwamasuntswana ezijikeleze amasuntswana aqinileyo, anokuthintela ngokwasemzimbeni amasuntswana angasondela, ngaloo ndlela kuncitshiswa ukubakho kwe-overgation kunye ne-sediment.
Uzinzo lwendawo: Ngenxa yobuso beemolekyuli ze-HPMC, unxibelelwano oluthile phakathi kwamasuntswana luncitshisiwe, kwaye lo mqobo uvumela amasuntswana amisiweyo ukuze ahlukane nexesha elide.
4. Umsebenzi womphezulu
Umsebenzi we-HPMC uyakuvumela ukuba i-adsorb kumphezulu wamasuntswana aqinileyo ukwenza ukuba isitali esizinzileyo. Oku kukhathazeka akuzinzisi kuphela umphezulu wamasuntswana, kodwa kukwaphucula i-hydrophility yamasuntswana, ibengela ukuba kube lula ukusasazeka kwimidiya yolwelo.
Ukulungiswa okungaphezulu
Ukucutha uxinzelelo oluhlanganisiweyo: Umsebenzi we-HPMC unokunciphisa uxinzelelo phakathi kwendawo engamanzi kunye nendawo ephantsi, yenze lula ukuba amasuntswana asasazeke ngokulinganayo.
Imizekelo yezicelo ze-HPMC kwiMision
Ukunqunyanyiswa kweziyobisi
Ukunqunyanyiswa ngamachiza, i-HPMC ihlala isetyenziselwa ukuzinzisa imeko yokusasazeka kwezithako ezisebenzayo. Ngokulungelelanisa uxinzelelo kunye nobunzima bemoya ye-HPMC, iipropathi ze-RIOOIL zokumiswa zinokulawulwa, ukuze izithako zeziyobisi zisasazwe ngokugcinwa nokusetyenziswa, ekuqinisekiseni ukungqinelana kokusebenza kakuhle.
Kunqunyazwayo ngomlomo kwamayeza athile okubulala iintsholongwane okanye amachiza athile, i-HPMC isetyenziswa njenge-thickener ukuthintela ukuntywila kwamasuntswana amachiza ngelixa ubonelela ngemikhono efanelekileyo kunye nolwelo.
Ukunqunyanyiswa kwe-pesticade
Ukumiswa kwezitshabalalisisi, i-HPMC inokuphucula ukusasazeka kwamasuntswana abulala izitshabalalisi emanzini kwaye inciphise i-Pesticides, ngaloo ndlela iphucule ukusebenza nokusebenza ngokukuko.
Kwisinambuzane okanye ukunqunyanyiswa kwe-herbicide, i-HPMC inokusetyenziswa njengomntu osasazekileyo kunye ne-tickener ukuqinisekisa ukuba izithako ezisebenzayo zokubulala izitshabalalisi zinokuhanjiswa ngokulinganayo ngexesha lokuphuhliswa kunye nokuphucula iziphumo zokhuseleko zokhuselo.
Ukutya kunye nokunqunyanyiswa kwe-cosmetic
Kwimizi-mveliso yokutya kunye ne-cosmetic, i-HPMC isetyenziswa ngokubanzi njenge-stibizer kunye ne-tickener. Umzekelo, kwiimveliso ezifana noku-emulssion okanye iikhrim, i-HPMC inokuphucula ukwenziwa kwemveliso kunye nokuthintela ukunyanzelwa kunye nokuchama.
Kwizikhrims zekhuselo, i-HPMC inokusetyenziswa njenge-thi chulener ukubonelela ngocolo olugudileyo kwaye ukomeleza iziphumo zemfundo, ukuze izithako ezisebenzayo zisasazwe ngokulinganayo, kwaye uzinzo lwemveliso lwemveliso ziphuculwe.
I-HPMC ichaphazela uzinzo lokunqunyanyiswa ngeendlela ezahlukeneyo, kubandakanya ukwanda kweziphumo, ukuphucula iziphumo ze-elektrostit, zibonelela ngesithintelo se-steric kunye nomsebenzi we-steric kunye nomsebenzi we-steric kunye nomsebenzi we-steric kunye nomsebenzi we-steric kunye nomsebenzi we-steric kunye nomsebenzi we-steric kunye nomsebenzi womhlaba. Ezi ndlela zisebenza kunye ukwenza i-HPMC isixhobo esisebenzayo sokuphucula uzinzo lokunqunyanyiswa. Isicelo sayo esibanzi kwicandelo lezonyango, izitshabalalisi, ukutya kunye nezinto zokuthambisa zibonisa ngakumbi izibonelelo zayo ezibalulekileyo njengezilothi. Kwixa elizayo, njengoko imfuno yezicelo zokumiswa ziyaqhubeka ukwanda, uphando kunye nokusetyenziswa kwe-HPMC kuya kuqhubeka ukukhululeka.
