Ko te Hydroxypropyl methylcellulose tetahi o nga taapiri ether cellulose nui i roto i te moata maroke me te maha o nga mahi i roto i te moata.Ko nga mahi matua o te hydroxypropyl methylcellulose i roto i te kumete ciment ko te pupuri wai me te matotoru.I tua atu, na tana taunekeneke ki te punaha ciment, ka taea hoki e ia te whai waahi ki te whakauru i te hau, te whakaroa i te waahi, me te whakapai ake i te kaha o te here.Te awe.
Ko te mahi nui o te hydroxypropyl methylcellulose i roto i te kumete ko te pupuri wai.Hei whakaurunga etera cellulose i roto i te kumete, ka taea te whakamahi i te hydroxypropyl methylcellulose i roto i te tata ki nga hua moata katoa, na te mea ko ona taonga pupuri wai.I te nuinga o te korero, ko te pupuri wai o te hydroxypropyl methylcellulose e pa ana ki tona pokey, te tohu whakakapinga me te rahi o te matūriki.
Ko te Hydroxypropyl methylcellulose e whakamahia ana hei kaitao, a, ko te kaha o te whakamaaramatanga e pa ana ki te tohu o te whakakapinga, te rahi o te matūriki, te viscosity me te tohu o te whakarereketanga o te hydroxypropyl methylcellulose.I te nuinga o te korero, ko te teitei ake o te whakakapinga me te viscosity o te cellulose ether, ka iti ake te rahi o te matūriki me te maarama ake o te paanga matotoru.
I roto i te hydroxypropyl methylcellulose, ko te whakaurunga o nga roopu methoxy ka whakaiti i te kaha o te mata o te wairewa wai kei roto te hydroxypropyl methylcellulose, na te hydroxypropyl methylcellulose he awe te hau ki te kumete ciment.Whakauruhia te nui o nga mirumiru ki roto i te kumete.Nā te "pānga pōro" o ngā mirumiru,
Ko te mahi hanga o te moata ka pai ake, ko te whakaurunga o nga mirumiru hau ka piki ake te hua o te moata.Ko te tikanga, me whakahaere te nui o te hau whakauru.Ina nui rawa te hau e uru ana, ka pa kino ki te kaha o te moata.
Ko te Hydroxypropyl methylcellulose ka whakaroa i te tukanga whakatakoto o te sima, ka whakaroa i te whakatakoto me te mahi whakapakeke o te ciment, me te whakaroa i te wa whakatuwheratanga o te kumete.Heoi, kaore tenei paanga e pai mo te kumete i nga waahi makariri.
Ka rite ki te matū polymer mekameka roa, ka taea e te hydroxypropyl methylcellulose te whakapai ake i te mahi honohono me te papanga turanga i te wa e mau tonu ana te makuku o te slurry ka whakauruhia ki te punaha sima.
Ko nga ahuatanga matua o te HPMC i roto i te kumete ko: te pupuri wai, te matotoru, te whakaroa i te waa whakatuu, te whakauru o te hau, te whakapai ake i te kaha here tensile, etc.
