Ko te Hydroxypropyl methyl cellulose ether (HPMC) te mahi o te pupuri i te wai me te whakapakeke i roto i te kumete ciment me te moata gypsum-based, a ka taea te whakapai ake i te taapiri me te aukati poutū o nga rauemi moata.
Ko nga mea penei i te pāmahana hau, te pāmahana me te tere o te pehanga hau ka pa he kino ki te tere o te whakaetonga o te makuku mai i te kumete ciment me nga hua o te gypsum. No reira, i ia wa, he rerekee te taapiri i te nui o nga hua hydroxypropyl methylcellulose ether (HPMC) hei pupuri i te pai o te wai.
I roto i te ringihanga raima, ka taea te whakatika i te paanga maukati wai ma te whakanui me te whakaheke i te rerenga hautanga. Ko te reeti pupuri wai o te hydroxypropyl methyl cellulose ether i te pāmahana teitei ko te uara tohu matua hei wehe i te kounga o te hydroxypropyl methyl cellulose ether.
Ka taea e nga hua hydroxypropyl methylcellulose (HPMC) te kounga teitei te whakaoti i te raruraru o te pupuri wai wera nui. I nga wa wera nui, ina koa i nga waahi wera me te makuku me te hanga chromatography, ka hiahiatia te hydroxypropyl methylcellulose ether (HPMC) kounga teitei hei whakapai ake i te pupuri wai o te slurry.
He tino pai te ahua o te hydroxypropyl methylcellulose ether (HPMC), a, ka tohatohahia ona roopu methoxyl me te hydroxypropyl i runga i te mekameka hanganga ngota o te methylcellulose, ka taea te whakatairanga i te whakatipuranga o nga ngota ngota hāora i runga i nga here hydroxyl me te ether. Te kaha ki te mahi me nga here kovalent.
Ka taea e ia te whakahaere pai i te whakaetonga o te wai na te wera o te rangi me te whakatutuki i te kaha o te aukati wai. Ka taea te whakamahi i te hydroxypropyl methylcellulose (HPMC) kounga teitei ki roto i nga mahi moata whakauru me nga mahi raima.
Whakauruhia nga matūriki totoka katoa ki te hanga i te kiriata makuku, ka tukuna te makuku i roto i te mahinga mo te wa roa, ka tauhohe ki nga mea kaiao me te collagen hei whakarite i te kaha o te hononga me te kaha.
Na reira, ki te whakaora i te wai i runga i te waahi hanga i te raumati wera, me taapiri nga hua o te hydroxypropyl methylcellulose (HPMC) kounga teitei kia rite ki te tohutaka, ki te kore, na te kore o te coagulation, te whakaheke i te kaha, Te pakaru, te pahu hau. me etahi atu raruraru o te kounga hua na te tere rawa o te whakamaroke.
Ka piki ake ano te uaua o te hanga mo nga kaimahi. I te hekenga o te pāmahana, ka heke haere te nui o te hydroxypropyl methylcellulose ether (HPMC) kia rite tonu te makuku.
