1. Kusunga Madzi: HPMC imatha kusintha kwambiri kusunga madzi mu matope, zomwe ndizofunikira kwambiri kuti matope asatayike madzi mwachangu panthawi yokonza madzi kutentha kwambiri, makamaka m'malo otentha kwambiri. Kusunga bwino madzi kumatsimikizira kuti simenti imalowa madzi okwanira komanso kumalimbitsa mphamvu ndi kulimba kwa matope.
2. Mphamvu yopindika ndi kupsinjika: Pa kutentha kochepa, HPMC ingachepetse mphamvu yopindika ndi kupsinjika ya zitsanzo za simenti pambuyo pa madzi a simenti chifukwa cha mpweya wolowa. Komabe, ngati simentiyo yasungunuka mu kufalikira kwa HPMC yosungunuka m'madzi, mphamvu yopindika ndi kupsinjika ya zitsanzo za simenti idzawonjezeka poyerekeza ndi simenti yomwe yasungunuka poyamba kenako n’kusakanizidwa ndi HPMC.
3. Kukana ming'alu: HPMC imatha kukonza modulus yotanuka ndi kulimba kwa matope, kuchepetsa bwino ming'alu, kukonza kukana ming'alu ya matope, ndikuwonjezera nthawi yake yogwira ntchito. Izi ndizofunikira makamaka pakusintha kwakukulu kwa kutentha, komwe nthawi zambiri kungayambitse matope kusweka.
4. Kukana ndi kukhazikika kwa alkali: HPMC ikhozabe kugwira ntchito bwino kwambiri m'malo opanda mchere popanda kuwonongeka kapena kuwonongeka kwa magwiridwe antchito, motero kuonetsetsa kuti matopewo akugwira ntchito bwino komanso kukhazikika kwa nthawi yayitali.
5. Kugwira ntchito kwa kutentha: Kuwonjezera kwa HPMC kumatha kupanga zinthu zopepuka ndikuchepetsa kulemera. Chiŵerengero cha void ichi chachikulu chimathandiza pakuteteza kutentha ndipo chingachepetse mphamvu zamagetsi za chinthucho pamene chikusunga pafupifupi mtengo wokhazikika pamene chikukhudzidwa ndi kutentha komweko. Kukana kutentha kudzera mu gululo kumasiyana malinga ndi kuchuluka kwa HPMC komwe kwawonjezeredwa, ndipo kuphatikiza kwakukulu kwa chowonjezeracho kumapangitsa kuti kutentha kukhale kolimba poyerekeza ndi kusakaniza kofananira.
6. Kusinthasintha ndi Kugwira Ntchito: HPMC ingathandize kuti matope awoneke bwino kwambiri pogwiritsa ntchito mphamvu zochepa zodulidwa ndipo ndi yosavuta kugwiritsa ntchito komanso kusinthasintha; pomwe matopewo ali ndi mphamvu zambiri zodulidwa, matopewo amasonyeza kukhuthala kwakukulu ndipo amaletsa Kutsika ndi kuyenda kwa madzi. Thixotropy yapaderayi imapangitsa kuti matopewo akhale ofewa panthawi yomanga, kuchepetsa kuvutika ndi mphamvu yomanga.
7. Kukhazikika kwa voliyumu: Kuwonjezera kwa HPMC kungakhudze kukhazikika kwa voliyumu ya matope. Mu matope odziyimira pawokha, kuwonjezera kwa HPMC kumapangitsa kuti ma pores ambiri akhalebe mumatope pambuyo poti matopewo akhazikika, zomwe zimapangitsa kuti mphamvu yokakamiza komanso mphamvu yosinthasintha ya matope odziyimira pawokha ichepe.
HPMC imakhudza kwambiri momwe matope amagwirira ntchito kutentha kwambiri. Imatha kupititsa patsogolo kusunga madzi, kukana ming'alu, kukana alkali komanso kugwira ntchito bwino kwa matope, komanso ingakhudze mphamvu yake ndi kukhazikika kwa voliyumu. Chifukwa chake, pakugwiritsa ntchito moyenera, mlingo ndi zofunikira za HPMC ziyenera kusankhidwa moyenera kutengera momwe zinthu zilili komanso zofunikira pakugwira ntchito bwino kwa matope kuti akwaniritse magwiridwe antchito abwino kwambiri.
