HPMC Gel Temperature Experiment
Ukuqhuba umfuniselo wejeli wobushushu beHydroxypropyl Methylcellulose (HPMC) kubandakanya ukumisela iqondo lobushushu apho isisombululo se-HPMC sifumana i-gelation okanye senze ijeli-i-consistency. Nantsi inkqubo jikelele yokwenza umfuniselo wobushushu bejeli:
Izinto ezifunekayo:
- I-Hydroxypropyl Methylcellulose (HPMC) powder
- Amanzi adityanisiweyo okanye isinyibilikisi (esifanele isicelo sakho)
- Umthombo wobushushu (umzekelo, ibhafu yamanzi, ipleyiti eshushu)
- Ubushushu bokulinganisa
- Intonga yokuvuselela okanye i-stirrer magnetic
- Iibhekile okanye izitya zokuxuba
- Isibali-xesha okanye istopwotshi
Inkqubo:
- Ukulungiswa kwesisombululo se-HPMC:
- Lungiselela uthotho lwezisombululo ze-HPMC ezinogxininiso olwahlukileyo (umzekelo, 1%, 2%, 3%, njl.) kumanzi adibeneyo okanye i-solvent oyikhethile. Qinisekisa ukuba i-HPMC powder ihlakazwe ngokupheleleyo kulwelo ukukhusela i-clumping.
- Sebenzisa isilinda esithweswe izidanga okanye ibhalansi ukulinganisa ubungakanani obufanelekileyo be-HPMC umgubo kwaye wongeze kulwelo ngelixa uvuselela ngokuqhubekayo.
- Ukuxuba kunye nokuNcitshiswa:
- Gxuma isisombululo se-HPMC ngokucokisekileyo usebenzisa intonga eshukumisayo okanye i-magnetic stirrer ukuqinisekisa ukuchithwa okupheleleyo komgubo. Vumela isisombululo ukuba sidibanise kwaye sigxininise imizuzu embalwa ngaphambi kokuvavanya ukushisa kwejeli.
- Ukulungiswa kweeSampuli:
- Galela isixa esincinci sesisombululo ngasinye se-HPMC esilungisiweyo kwiibhekile ezahlukeneyo okanye kwizikhongozeli. Faka ileyibhile isampuli nganye ngoxinaniso oluhambelanayo lwe-HPMC.
- Uhlengahlengiso lobushushu:
- Ukuba uvavanya umphumo weqondo lokushisa kwi-gelation, lungiselela ukuhlamba kwamanzi okanye indawo elawulwa yiqondo lokushisa ukutshisa izisombululo ze-HPMC.
- Sebenzisa i-thermometer ukujonga ubushushu bezisombululo kwaye ulungelelanise njengoko kuyimfuneko kwiqondo lokushisa lokuqala elifunwayo.
- Ukufudumeza nokuQwalasela:
- Beka iibhekile ezinezicombululo ze-HPMC kwindawo yokuhlambela yamanzi okanye kwindawo yobushushu.
- Ukufudumala izisombululo ngokuthe ngcembe, uvuselela ngokuqhubekayo ukuqinisekisa ukufudumeza okufanayo kunye nokuxuba.
- Ukubeka iliso kwizisombululo ngokusondeleyo kwaye ugcine naluphi na utshintsho kwi-viscosity okanye ukuhambelana njengoko ubushushu bukhula.
- Qala isibali-xesha okanye isitophuwotshi ukurekhoda ixesha elithathiweyo ukuze i-gelation yenzeke kwisisombululo ngasinye.
- Ukumiselwa koBubushushu beGel:
- Qhubeka ufudumeza izisombululo kuze kube yilapho i-gelation ibonwa, ibonakaliswe ngokunyuka okukhulu kwe-viscosity kunye nokwakhiwa kwe-gel-like consistency.
- Rekhoda iqondo lobushushu apho i-gelation yenzeka khona kugxininiso ngalunye lwe-HPMC oluvavanyiweyo.
- Uhlalutyo lwedatha:
- Hlalutya idatha ukuchonga naziphi na iintsingiselo okanye ulungelelwaniso phakathi koxinzelelo lwe-HPMC kunye nobushushu bejeli. Yenza isicwangciso seziphumo kwigrafu ukuba unqwenela ukuba nombono wobudlelwane.
- Utoliko:
- Ukutolika idatha yobushushu be-gel kumxholo weemfuno zakho zesicelo esithile kunye nokuqwalaselwa kokuqulunqwa. Qwalasela izinto ezifana ne-gelation kinetics efunekayo, iimeko zokulungisa, kunye nokuzinza kobushushu.
- Uxwebhu:
- Bhala inkqubo yovavanyo, kubandakanywa neenkcukacha zezisombululo ze-HPMC ezilungisiweyo, imilinganiselo yobushushu ethathiweyo, ukuqwalaselwa kwe-gelation, kunye nawo nawaphi na amanqaku ongezelelweyo okanye iziphumo ezivela kuvavanyo.
Ngokulandela le nkqubo, unokwenza umfuniselo wejeli wobushushu beHydroxypropyl Methylcellulose (HPMC) kwaye ufumane ulwazi oluxabisekileyo malunga nokuziphatha kwayo kwegelation phantsi koxinzelelo kunye neemeko zobushushu. Lungisa inkqubo njengoko kuyimfuneko ngokusekelwe kwiimfuno zovavanyo ezithile kunye nokufumaneka kwezixhobo.
