Ko te kumete whakauru makuku: ko te kumete whakauru he momo sima, he huinga pai, he whakauru me te wai, me te rite ki nga ahuatanga o nga momo waahanga, i runga i tetahi owehenga, i muri i te ine i te teihana whakaranu, i konatunatua, ka haria ki te waahi kei reira te whakamahia te taraka, a ka tomo ki roto ki te motuhake Rokiroki te ipu me te whakamahi i te ranunga mākū oti mo te wa i tohua.
Ka whakamahia te Hydroxypropyl methylcellulose hei kaihoko pupuri wai mo te kumete ciment me te retarder mo te kumete moata.I roto i te take o te gypsum hei here ki te whakapai ake i te tono me te whakaroa i te wa mahi, ko te pupuri i te wai o te HPMC ka aukati i te slurry ki te pakaru tere i muri i te whakamaroke, me te whakapai ake i te kaha i muri i te whakapakeke.Ko te pupuri i te wai he taonga nui o te HPMC hydroxypropyl methylcellulose, a he mea maaharahara ano hoki mo te maha o nga kaihanga moata whakauru makuku o te kainga.Ko nga mea e pa ana ki te paanga o te pupuri wai o te kumete whakauru makuku ko te nui o te HPMC kua tapirihia, te pokey o te HPMC, te pai o nga matūriki me te mahana o te taiao whakamahi.
E toru nga mahi matua o te hydroxypropyl methylcellulose HPMC i roto i te kumete-makuku, ko tetahi he tino pai te pupuri i te wai, ko tetahi atu ko te awe i runga i te rite me te thixotropy o te moata-makuku, me te tuatoru ko te taunekeneke me te ciment.Ko te pupuri i te wai o te cellulose ether e whakawhirinaki ana ki te tere o te whakauru wai o te turanga, te hanganga o te moata, te matotoru o te paparanga moata, te hiahia o te wai mo te moata, me te wa whakarite.Ko te teitei ake o te maarama o te hydroxypropyl methylcellulose, ka pai ake te pupuri wai.
Ko nga mea e pa ana ki te pupuri i te wai o te kumete whakauru makuku ko te pokey ether cellulose, te nui taapiri, te rahi matūriki me te pāmahana.Ko te nui ake o te pokey o te cellulose ether, ka pai ake te pupuri wai.Ko te Viscosity tetahi waahanga nui o te mahi HPMC.Mo te hua kotahi, he rereke nga hua o te whakamahi i nga tikanga rereke ki te ine i te pokey, a ko etahi he aputa rua.Na reira, ko te whakataurite o te viscosity me whakahaere i roto i te tikanga whakamatautau ano, tae atu ki te pāmahana, spindle, etc.
I te nuinga o te korero, ko te teitei ake o te viscosity, ko te pai ake o te pupuri wai.Engari, ko te teitei ake o te viscosity, ko te teitei ake o te taimaha ngota o te HPMC me te iti ake o te whakarewatanga o te HPMC, he kino te paanga ki te kaha me te mahi hanga o te moata.Ko te teitei ake o te pokey, ka tino kitea te hua o te moata, engari kaore i te hono tika.Ko te teitei ake o te viscosity, ko te kaha ake o te moata maku, ko te pai ake o te mahi hanga, ko te mahi o te kirikiri kirikiri me te teitei ake o te piri ki te taputapu.Heoi, ko te kaha ake o te hanganga o te kumete maku ake kaore e awhina.Ko nga hanganga e rua kaore he mahi anti-sag.He rerekee, he tino pai te kaha o te hangahanga o te moata maku.
Ko te nui ake o te nui o te cellulose ether e tapirihia ana ki te kumete makutu PMC, ka pai ake te pupuri i te wai, me te teitei ake o te pokey, ka pai ake te pupuri wai.Ko te pai he tohu mahi nui mo te hydroxypropyl methylcellulose.
Ko te pai o te hydroxypropyl methylcellulose he awe ano ki tana pupuri wai.I te nuinga o te waa, mo te hydroxypropyl methylcellulose he rite tonu te kiko me te rereke rereke, ko te iti ake o te pai, ko te iti ake o te paanga pupuri wai i raro i te nui o te taapiri.te pai ake.
I roto i te kumete makuku-whakaranu, he iti rawa te taapiri o te cellulose ether HPMC, engari ka taea te whakapai ake i te mahi hanga o te kumete maku, a ko te taapiri matua e pa ana ki te mahi o te kumete.Ko te whiriwhiri tika o te hydroxypropyl methylcellulose, ka tino pa te mahi o te kumete maku.
