Ukugcinwa kwamanziI-Hydroxypropyl Methyl Celluloseyenye yeempawu ezibalulekileyo zeHydroxypropyl Methyl Cellulose. Izinto ezifana nobushushu bomoya, ubushushu kunye nesantya soxinzelelo lomoya ziya kuchaphazela izinga lokuguquguquka kwamanzi kwisamente kunye neemveliso ezisekwe kwi-gypsum. Ke ngoko, ngamaxesha ahlukeneyo onyaka, kukho umahluko othile kwimpembelelo yokugcina amanzi kwiimveliso ezinomlinganiselo ofanayo weHydroxypropyl Methyl Cellulose eyongeziweyo.
Ngokubanzi, xa i-viscosity ye-Hydroxypropyl Methyl Cellulose iphezulu, kokukhona isiphumo sokugcina amanzi siya kuba ngcono, kodwa isiphumo se-viscosity ekugcinweni kwamanzi siya kuncipha xa i-viscosity idlula i-100,000 mpa. Kwi-Hydroxypropyl Methyl Cellulose ene-viscosity engaphezulu kwe-100,000, kuyimfuneko ukwandisa ubungakanani be-Hydroxypropyl Methyl Cellulose ukuze kwandiswe kakhulu izinga lokugcina amanzi.
Kwisakhiwo esithile, isiphumo sokugcina amanzi kwi-slurry sinokulungiswa ngokunyusa okanye ukunciphisa ubungakanani be-Hydroxypropyl Methyl Cellulose. Iimveliso zochungechunge lwe-Hydroxypropyl Methyl Cellulose zinokusombulula ngempumelelo ingxaki yokugcina amanzi phantsi kobushushu obuphezulu. Kumaxesha obushushu obuphezulu, ingakumbi kwiindawo ezishushu nezomileyo kunye nolwakhiwo oluncinci kwicala elinelanga, i-hydroxypropyl methylcellulose ekumgangatho ophezulu iyafuneka ukuphucula ukugcina amanzi kwi-slurry.
I-Hydroxypropyl Methyl Cellulose ekumgangatho ophezulu inobunye obuhle kakhulu. Amaqela ayo e-Methoxy kunye ne-Hydroxypropoxy asasazwa ngokulinganayo kwi-cellulose molecular chain. Ingaphucula ii-athomu ze-oxygen kwi-hydroxyl kunye ne-ether bonds. Amandla okudibana kwamanzi ukwenza ii-hydrogen bonds aguqula amanzi akhululekileyo abe ngamanzi abotshelelweyo, ngaloo ndlela ilawula ngempumelelo ukufuma kwamanzi okubangelwa yimozulu eshushu kakhulu kwaye ifezekise ukugcinwa kwamanzi okuphezulu.
Umgangatho ophezului-hydroxypropyl Methyl CelluloseIngasasazeka ngokulinganayo nangokufanelekileyo kwisamente kunye neemveliso ezisekwe kwi-gypsum, igoqe zonke iinxalenye eziqinileyo, ize yenze ifilimu emanzi, kwaye umswakama kwisiseko uya kukhululwa kancinci kancinci kwixesha elide. Kwenzeka i-hydration reaction kunye nezinto ze-inorganic gelling, ngaloo ndlela kuqinisekiswa amandla okubopha kunye namandla okucinezela kwezinto. Ke ngoko, kulwakhiwo lwasehlotyeni olushushu kakhulu, ukuze kufezekiswe isiphumo sokugcina amanzi, kuyimfuneko ukongeza iimveliso zeHydroxypropyl Methyl Cellulose ezikumgangatho ophezulu ngobuninzi obaneleyo ngokwefomula, kungenjalo, ukungabi namanzi okwaneleyo, amandla anciphileyo, kunye nokuqhekeka kuya kwenzeka ngenxa yokomisa kakhulu. Iingxaki zomgangatho ezifana nokugoba, ukugoba kunye nokuwa nazo zonyusa ubunzima bokwakha kubasebenzi. Njengoko ubushushu buhla, ubungakanani beHydroxypropyl Methyl Cellulose eyongeziweyo bunokuncipha kancinci, kwaye isiphumo esifanayo sokugcina amanzi sinokufezekiswa.
