I-HPMC, ekwabizwa ngokuba yi-hydroxypropyl methylcelceluplose, sisiseko esisebenzayo kakhulu kwishishini lokwakha, ngakumbi ekwenzeni udonga lube. Udonga lwe-udoli lusetyenziselwa ukulungiselela kunye nenqanaba lenqanaba ngaphambi kokupeyinta, ngaloo ndlela kubonelela ngokugqibeleleyo.
Abakhi abaninzi baye baneengxaki zokungena kwixesha elidlulileyo. I-Sag yenzeka xa i-DATTY iqala ukuwela eludongeni ngenxa yobunzima bayo. Oku kubangela ukuba kubekhona kwaye kungafundiswanga kugqitywe ixesha elininzi kunye nomzamo wokulungisa. Nangona kunjalo, abakhi bafumene isisombululo ngokudibanisa i-HPMC eludongeni, olunceda ekuphuculeni ukungaxhathisi i-SAG kunye nomgangatho opheleleyo wemveliso yokugqibela.
Kukho izizathu ezininzi zokuba i-HPMC yeyokuphumelela. Okokuqala, isebenza njenge-thi coker, oko kuthetha ukuba inceda ukwandisa i-visty yezinto ezibonakalayo. Oku kwandiswa kwe-viscosity kwenza kube nzima ukuba i-velode isuswe eludongeni kwaye iqhubekise ngcono ukunamathela okungcono kumphezulu. I-viscofity ephuculweyo ye-DOTTY ikwanceda ukuba igcwalise i-microccracks kunye neendawo ezincinci ezindongeni, zibonelela ngomphezulu othe tyaba, ngaphezulu. Eli nqaku likwanceda ukunciphisa inani le-putty efunekayo ukugubungela indawo engaphezulu yomphezulu, ngenxa yesisombululo esisebenzayo ngakumbi.
Okwesibini, i-HPMC idlala indima ebalulekileyo ekulawuleni isantya sowoyikayo se-ifakeli. Isantya esomileyo sichaphazela ngokuthe ngqo ukunganyangeki kwe-SAG, kwaye i-itall ye-itty eye eyomileyo ihlala izinzile kwaye akukho lula kwi-SAG. I-HPMC inceda ukulawula izinga lokuvela kwamanzi kwizinto ezibonakalayo, ezichaphazela ixesha lokwakha. Oku kubonelela ngoncedo kubangela ukuba kubekho izinzile ngakumbi kunye nokungaguquguqukiyo okwenzayo, ukunciphisa ithuba lokungena.
I-HPMC inokusetyenziselwa ukuphucula ububi phakathi kokubeka eludongeni kunye nomhlaba. Ukunamathela kubhekisa kwinqanaba lokuba izinto ezibonakalayo zihambelane nezinto ezenziwayo kumphezulu kuwo. I-HPMC inokuphucula kakhulu ubumbisi kuba ibonelela ngefilimu yokukhusela kumphezulu, ophucula i-bumbedon ye-ifaker kwi-subsest.
Ukongeza, i-HPMC inokukunceda ukugcina umswakama kwizinto ezinamachaphaza. Nangona amanzi elona nqanaba liphambili lokuqhubekeka nokuqiniseka, oko kukuthi, okona kuqhelekileyo kokuqhekeka kwaye kukhawuleze umbandela xa amanzi enyuka kakhulu. I-HPMC inceda ukugcina umswakama kwizinto ezibonakalayo ixesha elide, ivumela i-putty yokuzinza ngokulinganayo kwaye yomile ngaphandle kokukhala.
Ukuzama ukuphelisa, i-HPMC yintshatsheli ebalulekileyo kunye nokusebenza kwendlela enodonga, edlala indima ebalulekileyo ekwandiseni impahla echasene nodonga. Ngolawulo lwexabiso layo eliqaqambileyo, lokuphuculwa kwenqanaba lokulinganisa, ukuphuculwa komnxeba kunye neepropathi zokugcina amanzi, i-HPMC inikezela ngolwakhiwo lwezisombululo ezisebenzayo kwiingxaki ze-SAG kwaye kuphucula umgangatho wemveliso yokuphela. Inzuzo ayikho kuphela kwi-sunorther kuphela, igqitywe ngakumbi, kodwa nakwiindleko zesisombululo. Ke ngoko, kuyimfuneko ukuba uqonde kwaye ugxininise indima engekhoyo ye-HPMC kwishishini lokwakha.
