Izifundo ze-RheOmological ye-HydroxyPOpyl Methylcelculose (HPMC) Iinkqubo ze-chickener zibaluleke kakhulu ekuqondeni indlela yokuziphatha yabo kwizicelo ezahlukeneyo, ezivela kumayeza okutya kunye ne-cosmetics. I-HPMC sisisele i-Ether Ithe Storsunitive ifakwe ngokubanzi njenge-arhente yokuthambisa, i-stabilizer, kunye ne-mulsifier ngenxa yokukwazi ukuguqula iipropathi ze-ROSOST kunye nothintelo.
Imemovissity iMilinganiselo:
I-Viscosity yenye yezona ndawo zibalulekileyo zeRhemological ezifundwe kwiinkqubo ze-HPMC. Iindlela ezahlukeneyo ezifana nokuchasa ngokujikelezayo, i-capillary vist, kwaye i-oscillat rheometry iqeshwe ukulinganisa i-viscofity.
Ezi zifundo ziyimpembelelo yezinto ezinjenge-HPMC, ubunzima bemoyare, isidanga sokufakwa endaweni, ubushushu, kunye nexabiso le-Shear kwi-vickosity.
Ukuqonda i-viscofity ibaluleke kakhulu njengoko kumisela indlela yokuhamba, uzinzo, kunye nokufaneleka kwesicelo se-HPMC eqingqiweyo.
2.Ke-i-pitring yokuziphatha:
Izisombululo ze-HPMC ngokwesiqhelo zibonisa indlela yokuziphatha ye-Shear, ethetha ukuba i-viscofity yabo ihla ngenqanaba lokwanda kwenqanaba.
Izifundo ze-roheeological zisebenza kwindawo yokuthoba isheracar kunye nokuxhomekeka kwayo kwizinto ezinjenge-polymer gxini kunye nobushushu.
Ukuphawula indlela yokuziphatha ye-Shearling kubalulekile kwizicelo ezinje nge-carhengs kunye neencwadana, apho ukuhamba, khona ukuhamba ngexesha lokufaka isicelo kunye nokuzinza emva kokuba isicelo sibalulekile.
I-3.thixiXorpy:
I-Thixotropy ibhekisa kwixesha lokubuyiselwa kwexesha lokujonga kwakhona emva kokususwa koxinzelelo lweShear. Iinkqubo ezininzi ze-HPMC zibonisa indlela yokuziphatha ye-Tixitropic, enesibonelelo kwizicelo ezifuna ukuhamba okulawulwayo kunye nokuzinza.
Izifundo ze-Rhecialogi ibandakanya ukuvumela kwakhona ukubuyiselwa kwe-viscofity ngexesha emva kokuthoba inkqubo yokuphatha uxinzelelo.
Ukuqonda i-ThixioldyOpys ekuqulunqweni kweemveliso ezinjengeepeyinti, apho uzinzo ngexesha lokugcina kunye nokukhululeka kwesicelo kubalulekile.
4.Berage:
Ngaphezulu kweengcinezelo okanye ngeekopi ezithile ezithile, izisombululo ze-HPMC zinokwenza ubume, zenza ubume benethiwekhi.
Izifundo ze-roheeologing phanda indlela yokuziphatha ephathelele kwimibandela efana noxinzelelo, ubushushu kunye ne-pH.
Izifundo zeQela lokuKhula zibalulekile ekuyingeni ukwenziwa kweziyobisi kunye nokudala iimveliso ezisekwe kwi-gel-esekwe kwi-jel kunye nemizi-mveliso yononophelo.
Uphawu lomongamela:
Iindlela zobuchule ezinje nge-X-ray-ray ye-X-ray sfrate (i-SAXs) kunye ne-Rheo-SAXS ibonelela ngengqondo kulwakhiwo lwenkqubo ye-HPMC.
Ezi zifundo zibonisa ulwazi malunga ne-Polymer Chain thys, indlela yokuziphatha yoqoqosho, kunye nokunxibelelana ngeemolekyuli zeSolvent.
Ukuqonda imiba yesakhiwo inceda ekuqikeleleni indlela yokuziphatha ye-sucroscopic ye-macroscopic kunye nokwenziwa kweenkqubo ezifanelekileyo zeepropathi.
6.Uhlalutyo lwe-6.MOmic Meyitical Meyitical (DMA):
I-DMA ilinganisa ipropathi ye-viscoestic yezixhobo eziphantsi kwe-oscillatory.
Izifundo ze-RheOoalogical zisebenzisa iiparamitha ze-DMA ELCIDES ezifana nogcino (G '), ilahleko yelahleko (G "), kunye nomsebenzi ontsonkothileyo njengomsebenzi weqondo lokuhlala kunye nobushushu.
I-DMA iluncedo kakhulu ekubonakaliseni isimilo esifanayo kunye nokuziphatha ngokungafaniyo nee-HPMC ze-HPMC kunye neePasile.
7. Izifundo zokuqala-:
Izifundo ze-RheOdialoging zilungiselelwe izicelo ezithile ezinjengeepilisi zamachiza, apho i-HPMC isetyenziswa njengendawo yokubhabha, okanye kwiimveliso zokutya ezinjengesosi kunye nokunxiba, apho isebenza njengendawo eyi-thickener kunye nokuzinzisa.
Ezi zifundo zilungiselela ukwenziwa kwe-HPMC yeepropathi ezinqwenelekayo zokuhamba, ukuthungwa, kunye nokuzinza kweshesi, ukuqinisekisa ukusebenza kwemveliso kunye nokwamkelwa kwabathengi.
Izifundo ze-roheeology zidlala indima ebalulekileyo ekuqondeni indlela yokuziphatha enzima yeenkqubo ze-HPMC ezinkulu. Ngokubonisa i-viscofity efihlakeleyo, ukuncipha kwe-Shear, Thiatropy, iMifanekiso ekhethekileyo, kunye nePropathi yeZicelo, ezi zifundo ziqhuba uyilo olusekwe kwi-HPMC kumashishini ahlukeneyo.
