Ko te pupuri wai maiHydroxypropyl Methyl CelluloseKo tetahi o nga mea nui o Hydroxypropyl Methyl Cellulose. Ko nga mea penei i te mahana o te hau, te pāmahana me te tere o te pehanga hau ka pa ki te tere o te whakaheke o te wai i roto i te kumete ciment me nga hua mai i te gypsum. No reira, i nga wa rerekee, he rerekee te paanga o te pupuri wai o nga hua me te nui o te Hydroxypropyl Methyl Cellulose te taapiri.
Ko te tikanga, ko te teitei ake o te viscosity o Hydroxypropyl Methyl Cellulose, ka pai ake te painga o te pupuri wai, engari ka iti ake te paanga o te viscosity ki te pupuri wai ina neke ake te viscosity i te 100,000 mpa.s. Mo te Hydroxypropyl Methyl Cellulose me te viscosity neke atu i te 100,000, he mea tika ki te whakanui ake i te nui o te Hydroxypropyl Methyl Cellulose ki te whakanui ake i te tere o te pupuri wai.
I roto i te hanga motuhake, ka taea te whakarereke i te paanga o te pupuri wai o te slurry ma te whakanui, te whakaheke ranei i te nui o te Hydroxypropyl Methyl Cellulose. Ka taea e nga hua raupapa Hydroxypropyl Methyl Cellulose te whakaoti i te raruraru o te pupuri wai i raro i te wera nui. I nga wa wera nui, ina koa i nga waahi wera me nga waahi maroke me te hanga angiangi-papa ki te taha paki, ka hiahiatia te hydroxypropyl methylcellulose-kounga teitei hei whakapai ake i te pupuri wai o te slurry.
Ko te Hydroxypropyl Methyl Cellulose te kounga teitei he tino pai te rite. Ko ona roopu Methoxy me te Hydroxypropoxy kua tohatoha noa ki te taha o te mekameka ngota cellulose. Ka taea te whakapai ake i nga ngota hāora i runga i nga hononga hydroxyl me te ether. Ko te kaha o te whakakotahitanga wai ki te hanga i nga here hauwai ka huri te wai kore ki roto i te wai herea, na reira ka whai hua te whakahaere i te whakaetonga wai i puta mai i te huarere-nui me te pupuri i te wai teitei.
Te kounga teiteihydroxypropyl Methyl Celluloseka taea te marara i roto i te kumete ciment me nga hua gypsum, te takai i nga matūriki totoka katoa, ka hanga he kiriata makuku, a ka tukuna te makuku i roto i te turanga mo te wa roa. Ka puta he tauhohenga wai me te rauemi whakaraera parakore, na reira ka whakapumau i te kaha o te here me te kaha kopiri o te rauemi. Na reira, i roto i te hanga o te raumati wera nui, kia tutuki ai te paanga o te pupuri wai, he mea tika ki te taapiri i nga hua o te Hydroxypropyl Methyl Cellulose kounga teitei i roto i nga rahinga e rite ana ki te tauira, ki te kore, karekau te wai, ka heke te kaha, ka pakaru mai na te nui o te whakamaroke. Ko nga raru o te kounga penei i te kowhao, te kowhao me te takahanga ka piki ake te uaua o te hanga mo nga kaimahi. I te hekenga o te pāmahana, ka taea te whakaheke haere te nui o te Hydroxypropyl Methyl Cellulose i tapirihia, ka taea te whakatutuki i te paanga pupuri wai ano.
