Kwi-samente mortar kunye ne-gypsum-based slurry, i-HPMC idlala indima yokugcina amanzi kunye nokuqina. Ingaphucula ngempumelelo amandla okubopha kunye ne-anti-pituitarism ye-slurry.
Ubushushu bomoya, ubushushu bomoya kunye nesantya soxinzelelo lomoya zichaphazela izinga lokuwohloka kwamanzi kwisamente kunye neemveliso ezisekwe kwi-gypsum.
Ngamaxesha onyaka ahlukeneyo, kukho umahluko othile kwisiphumo sokugcina amanzi se-HPMC. Kwisakhiwo esithile, isiphumo sokugcina amanzi se-slurry sinokulungiswa ngokunyusa okanye ukunciphisa inani le-HPMC elongeziweyo. Ukugcinwa kwamanzi kwe-methyl cellulose ether phantsi kweemeko zobushushu obuphezulu luphawu olubalulekileyo lokwahlula umgangatho we-methyl cellulose ether. Iimveliso ezibalaseleyo zochungechunge lwe-HPMC zinokusombulula ngempumelelo ingxaki yokugcina amanzi phantsi kobushushu obuphezulu.
Kwixesha lobushushu obuphezulu, ingakumbi kwiindawo ezishushu nezomileyo kunye nolwakhiwo oluncinci kwicala elinelanga. I-HPMC esemgangathweni ophezulu iyafuneka ukuphucula ukugcinwa kwamanzi kwe-slurry. Ingaphucula amandla e-athomu yeoksijini kwiqela le-hydroxyl ukwenza i-hydrogen bond kunye ne-ether bond. Yenza amanzi akhululekileyo abe ngamanzi abotshelelweyo, ukuze kulawulwe ngempumelelo ukufuma kwamanzi okubangelwa yimozulu eshushu kakhulu. Inqanaba eliphezulu lokugcinwa kwamanzi.
I-HPMC ye-cellulose ekumgangatho ophezulu inokusasazeka ngokulinganayo nangokufanelekileyo kwi-samente mortar kunye neemveliso ezisekwe kwi-gypsum. Kwaye ugoqe zonke iinxalenye eziqinileyo ukuze wenze ifilimu yokumanzisa. Ukufuma kumaleko osisiseko kukhululwa kancinci kancinci ixesha elide, kwaye izinto ze-gelling ezingaphiliyo zifumana impendulo yokumanzisa. Ngaloo ndlela kuqinisekiswa amandla okubopha kunye namandla okucinezela kwezinto. Ke ngoko, kufuneka zakhiwe kubushushu obuphezulu basehlotyeni ukuze kufezekiswe isiphumo sokugcina amanzi. Qiniseka ukuba wongeza iimveliso ze-HPMC ezikumgangatho ophezulu ngokwefomula, kungenjalo kuya kubakho iingxaki zomgangatho ezifana nokungoneli kokuhambisa amanzi. Kodwa ikwanyusa ubunzima bokwakha babasebenzi. Njengoko ubushushu buhla, ubungakanani be-HPMC bunokuncipha kancinci kancinci, kwaye nesiphumo sokugcina amanzi sinokufezekiswa.
