I-HPMC (Hydroxypropyl methylcelcelcelsulose)Ngaba i-polymer isetyenziswe ngokubanzi kwiimveliso zesamente. Ine-curketions egqwesileyo, isasaza, ukugcinwa kwamanzi kunye nepropathi yokuthoba, ke inokuyiphucula kakhulu intsebenzo yeemveliso zesamente. Kwinkqubo yemveliso kunye nesicelo sezinto zesamente, bahlala bejamelana neengxaki ezinjengokuphucula ukungathobeki, ukuphucula ukunganyangeki kwamandla, kunye nokuphucula amandla. Ukongezwa kwe-HPMC kunokuthiwa ngokufanelekileyo kwezi ngxaki.
1. Phucula ulwelo kunye nokusebenza kwesamente
Kwinkqubo yemveliso yeemveliso zeceng, ulwelo yinto ebalulekileyo echaphazela imisebenzi yokwakha kunye nomgangatho wemveliso. Njenge-Polymer Thickener, i-HPMC inokwenza indawo yokuziqhelanisa nenethiwekhi kwisamente ye-Slourry, ngaloo ndlela kuphucule ukwenziwa kolwelo kunye nokusebenza kwesilayidi. Inganciphisa kakhulu umahluko we-viscosity yesamente etyibilika, esenza iplastiki engaphezulu kwaye ilungele ukwakhiwa nokugalela. Ukongeza, i-HPMC inokugcina ukufana kwesamente etyibilika, khusela isamente yokutsalwa kwesandla xa sahlulela ngexesha lokuxuba, kwaye uphucule ugcino ngexesha lenkqubo yokwakha.
2. Ukuphucula ukugcinwa kwamanzi kwiimveliso zesamente
Inkqubo ye-hydration yesamente sisitshixo sokusekwa kwamandla eemveliso zesamente. Nangona kunjalo, ukuba amanzi kwisamente etyibilika okanye alahlekile ngokukhawuleza, impendulo ye-hydration isenokungaphelelanga, ngaloo ndlela ichaphazela amandla kunye nokuqulunqwa kweemveliso zesamente. I-HPMC inogcino oluqinileyo lwamanzi, olunokufumana amanzi ngokufanelekileyo, ukulibazisa ukuvela kwamanzi, nokugcina ukufuma kwesamente nge-cerry ngesamente, ngaloo ndlela ichaphazela amandla kunye namandla e Iimveliso zesamente. Uxinzelelo.
3. Ukuphucula ukunganyangeki kotywala kunye nobunzima beemveliso zesamente
Iimveliso zesamente zithambekele ekubeni kuqhekezwe ngexesha lenkqubo ebukhali, ngakumbi i-shrinkgety ye-shrink ebangelwa kukulahleka ngokukhawuleza komswakama ngexesha lenkqubo yokomisa. Ukongezwa kwe-HPMC kunokuphucula ukunganyangeki kweemveliso zesamente ngokwandisa i-viscoelity ye-viscoelity yesilayidi. Isakhiwo se-MPMC sinokwenza ulwakhiwo lwenethiwekhi kwisamente, elinceda ukusasaza uxinzelelo lwangaphakathi kunye nokunciphisa uxinzelelo lwe-shrinkige ngexesha lokwenza amandla, ngaloo ndlela kuncitshiswe ngokufanelekileyo. Ukongeza, i-HPMC inokuphucula ubunzima beemveliso zesamente, zenza ukuba zibe ngaphantsi kokuqhekeza phantsi kweemeko ezomileyo okanye zeqondo lobushushu.
4. Phucula ukunyangwa kwamanzi kunye nokuqina kweemveliso zesamente
Ukuqina kunye nokuxhathisa kwamanzi kweemveliso zesamente kubaluleke ngokunxulumene ngqo nokusebenza kwabo kwiindawo ezinobunzima. I-HPMC inokwenza ifilimu enokuzinza kwisamente ityibilika ukunciphisa ukungena komswakama kunye nezinye izinto eziyingozi. Ingaphucula ukumelana kwamanzi kweemveliso zesamente ngokuphucula ukuxinana kwesamente kunye nokwandisa ukuxhathisa kweemveliso zesamente. Ngexesha lokusetyenziswa kwexesha elide, iimveliso zesamente zizinzile kakhulu kumswakama ophezulu okanye kwiindawo ezingaphantsi kwamanzi, azinakuthambeka ekuphelisweni nasekukhukuliseni, kwaye zandise ubomi beenkonzo zabo.
5. Phinda uphucule amandla kunye nesantya esikhundleni seemveliso zesamente
Ngexesha lenkqubo yokuphendula i-hydration yeemveliso zesamente, ukongezwa kwe-HPMC kunokukhuthaza ukusasazeka kwamasuntswana kwisamente kwaye kwandise indawo yoqhakamshelwano kunye nenqanaba lokukhula kwamandla kunye namandla okukhula kwesamente. Ukongeza, i-HPMC inokwandisa ukusebenza kakuhle kwesamente kunye namanzi, ukuphucula ukukhula kwamandla, yenza inkqubo yokukhula kweemveliso zesamente ngakumbi, kwaye ke phucula amandla okugqibela. Kwezinye izicelo ezikhethekileyo, i-HPMC inakho ukuhlengahlengisa inqanaba lomhlokhodi yesamente ukuze lihambelane neemfuno zokwakha kwiindawo ezahlukeneyo.
I-6. Ukuphucula imbonakalo kunye nomgangatho womhlaba weemveliso zesamente
Umgangatho wokubonakala weemveliso zesamente ubalulekile kwifuthe lokusetyenziswa kokugqibela, ngakumbi kwiimveliso zokuphela kunye nokuhombisa, apho iflethi kunye nembonakalo yembonakalo yenye yezona zinto ziphambili zokulinganisa umgangatho. Ngokuhlengahlengisa i-viscofity kunye nepropathi ye-gesiology yesamente etyibilika, i-HPMC inokukunciphisa ngempumelelo iingxaki ezinje ngeebhabhu, iziphene, nokwenza umphezulu weemveliso zesamente kwaye uphucule umgangatho wokubonakala. Kwezinye iimveliso zokuhombisa, ukusetyenziswa kwe-HPMC kunokuphucula ukufana kunye nokuzinza kombala wabo, ukunika iimveliso zibonakala zicocekile ngakumbi.
7. Ukuphucula ukumelana nengqele yeemveliso zesamente
Iimveliso zesamente ezisetyenziselwa indawo yobushushu ephantsi kufuneka ibe nenqanaba elithile lokungaxhathisi beqanda ukuthintela imingxunya kunye nomonakalo obangelwe yimijikelezo ye-freeze-suw. I-HPMC inokuphucula ukuxhathisa iqabaka yeemveliso zesamente ngokwandisa uzinzo lwesamente. Ngokuphuculwa kwengqungquthela yeemveliso zesamente kunye nokunciphisa umxholo wokufuma, i-HPMC iphucula ukumelana neemveliso zesamente phantsi komonakalo wobushushu obangelwe kukwandiswa kwamanzi.
Ukusetyenziswa kweI-HPMCKwiimveliso zesamente zinoluhlu olubanzi lweenzuzo kwaye lunokuphucula kakhulu ukusebenza kweemveliso zesamente ngeendlela ezahlukeneyo ngeendlela ezahlukeneyo. Ayinakuphucula nje ulwelo, ukugcinwa kwamanzi, ukungcungcutheka kunye namandla eemveliso zesamente, kodwa kukuphucula umgangatho womhlaba, ukuqina kunye nokunganyangeki kweemveliso zesamente. Njengoko ishishini lokwakha liyaqhubeka nokuphucula iimfuno zomsebenzi weemveliso zesamente, i-HPMC iya kusetyenziswa ngakumbi ukubonelela ngenkxaso yentsebenzo efanelekileyo nefanelekileyo yokuvelisa kunye nokusetyenziswa kweemveliso zesamente.
