1. Ukugcinwa kwamanzi: I-HPMC ingathuthukisa kakhulu ukugcinwa kwamanzi kwe-mortar, okubalulekile ekuvimbeleni i-mortar ukuthi ingalahlekelwa amanzi ngokushesha ngesikhathi senqubo yokulungisa ngaphansi kwamazinga okushisa aphezulu, ikakhulukazi ezindaweni ezishisa kakhulu. Ukusebenza kahle kokugcinwa kwamanzi kuqinisekisa ukumuncwa okwanele kwe-samente futhi kuthuthukisa amandla nokuqina kwe-mortar.
2. Amandla okugobeka kanye namandla okucindezela: Ngaphansi kwezimo zokushisa eziphansi, i-HPMC inganciphisa amandla okugobeka kanye nokucindezela kwamasampula esimende sensimbi ngemva kokugobeka kwesimende ngenxa yokufakwa komoya. Kodwa-ke, uma usimende ugobeka ekusakazekeni kwe-HPMC encibilikiswe emanzini, amandla okugobeka kanye nokucindezela kwamasampula esimende sensimbi azokhula uma kuqhathaniswa nalawo agcotshwe kuqala bese exutshwa ne-HPMC.
3. Ukumelana nokuqhekeka: I-HPMC ingathuthukisa i-modulus enwebekayo kanye nokuqina kwe-mortar, inciphise ngempumelelo ukuqhekeka, ithuthukise ukumelana nokuqhekeka kwe-mortar, futhi yandise impilo yayo yokusebenza. Lokhu kubaluleke kakhulu ngesikhathi sokushintsha okukhulu kwezinga lokushisa, okungabangela ukuthi i-mortar iqhekeke.
4. Ukumelana nokuqina kwe-alkali: I-HPMC isakwazi ukugcina ukusebenza kwayo okuhle kakhulu endaweni ene-alkaline ngaphandle kokuwohloka noma ukuwohloka kokusebenza, ngaleyo ndlela iqinisekise ukusebenza kahle kwesikhathi eside kanye nokuqina kwe-mortar.
5. Ukusebenza kokushisa: Ukwengezwa kwe-HPMC kungakhiqiza izinto ezilula futhi kunciphise isisindo. Lesi silinganiso se-void esiphezulu sisiza ngokufakwa kokushisa futhi singanciphisa ukuhanjiswa kukagesi kwezinto ngenkathi kugcinwa cishe inani elihleliwe lapho kufakwa ukushisa okufanayo. Ukumelana nokudluliselwa kokushisa ngephaneli kuyahlukahluka ngenani le-HPMC elingeziwe, lapho ukufakwa okuphezulu kwesithasiselo kuholela ekwandeni kokumelana kokushisa uma kuqhathaniswa nengxube yokubhekisela.
6. Ukugeleza kanye nokusebenza kahle: I-HPMC ingenza udaka lubonise ukugeleza okungcono ngaphansi kwamandla aphansi okucheba futhi kulula ukulusebenzisa kanye nokulingene; ngenkathi lungaphansi kwamandla aphezulu okucheba, udaka lukhombisa ukujiya okuphezulu futhi luvimbela ukugoba nokugeleza. Le thixotropy eyingqayizivele yenza udaka lube lula ngesikhathi sokwakha, kunciphisa ubunzima bokwakha kanye nobunzima bokusebenza.
7. Ukuqina komthamo: Ukwengezwa kwe-HPMC kungathinta ukuqina komthamo womgqomo. Kumgqomo ozilinganisayo, ukwengezwa kwe-HPMC kubangela ukuthi inani elikhulu lama-pores lihlale ku-mortar ngemva kokuba umgqomo uqinile, okuholela ekunciphiseni kwamandla okucindezela kanye namandla okuguquguquka komgqomo ozilinganisayo.
I-HPMC inomthelela omkhulu ekusebenzeni kwe-mortar ngaphansi kwamazinga okushisa aphezulu. Ingathuthukisa ukugcinwa kwamanzi, ukumelana nokuqhekeka, ukumelana ne-alkali kanye nokusebenza kokushisa kwe-mortar, kodwa futhi ingathinta amandla ayo kanye nokuqina komthamo. Ngakho-ke, ekusetshenzisweni okungokoqobo, umthamo kanye nemininingwane ye-HPMC kudingeka kukhethwe ngokufanele ngokusekelwe ezimweni ezithile zemvelo kanye nezidingo zokusebenza ukuze kufezwe ukusebenza kwe-mortar okungcono kakhulu.
