Kudaka lwesamente kunye ne-gypsum-based slurry, i-HPMC idlala indima enkulu yokugcina amanzi kunye nokujiya. Inokuphucula ngokufanelekileyo amandla okubopha kunye ne-anti-pituitarism ye-slurry.
Ubushushu bomoya, ubushushu bomoya kunye nesantya soxinzelelo lomoya kuchaphazela izinga lokuguquguquka kwamanzi kudaka lwesamente kunye neemveliso ezisekelwe kwigypsum.
Kumaxesha onyaka ahlukeneyo, kukho umahluko othile kwisiphumo sogcino lwamanzi lwe-HPMC. Kulwakhiwo oluthile, umphumo wokugcinwa kwamanzi we-slurry unokulungiswa ngokunyuka okanye ukunciphisa inani le-HPMC elongezelelweyo. Ukugcinwa kwamanzi kwe-methyl cellulose ether phantsi kweemeko eziphezulu zeqondo lokushisa luphawu olubalulekileyo lokuhlukanisa umgangatho we-methyl cellulose ether. Iimveliso ezigqwesileyo ze-HPMC zinokusombulula ngempumelelo ingxaki yokugcinwa kwamanzi phantsi kobushushu obuphezulu.
Ngexesha lobushushu obuphezulu, ngokukodwa kwiindawo ezishushu nezomileyo kunye nokwakhiwa kwe-thin-layer kwicala lelanga. Umgangatho ophezulu we-HPMC uyafuneka ukuphucula ukugcinwa kwamanzi eludaka. Inokuphucula amandla e-athomu ye-oxygen kwiqela le-hydroxyl ukwenza ibhondi ye-hydrogen kunye ne-ether bond. Yenza amanzi akhululekileyo kumanzi abophekileyo, ukuze ulawule ngokufanelekileyo ukuphuphuma kwamanzi okubangelwa yimozulu ephezulu. Inqanaba eliphezulu lokugcina amanzi.
I-HPMC yomgangatho ophezulu we-cellulose inokusasazwa ngokulinganayo nangokufanelekileyo kudaka lwesamente kunye neemveliso ezisekelwe kwigypsum. Kwaye gubungela zonke iinqununu eziqinileyo ukwenza ifilimu yokumanzisa. Ukufuma kwisiseko sesiseko kukhutshwa ngokuthe ngcembe ixesha elide, kwaye i-inorganic gelling material ifumana impendulo ye-hydration. Ngaloo ndlela iqinisekisa amandla ebhondi kunye namandla acinezelayo ezinto eziphathekayo. Ke ngoko, kufuneka yakhiwe kwiqondo lobushushu obuphezulu ehlotyeni ukuze kufumaneke umphumo wokugcina amanzi. Qiniseka ukuba ukongeza iimveliso HPMC ezikumgangatho ophezulu ngokwefomula, kungenjalo kuya kubakho iingxaki umgangatho ezifana nokungonelanga hydration. Kodwa ikwanyusa nobunzima bokwakha babasebenzi. Njengoko iqondo lobushushu liyehla, inani le-HPMC lingancitshiswa ngokuthe ngcembe, kwaye umphumo wokugcinwa kwamanzi nawo unokufezekiswa.
