He rite tonu ngā mahi a te HPMC me te HEMC i roto i ngā rauemi hanga. Ka taea te whakamahi hei whakamarara, hei pupuri wai, hei whakamātotoru me te here, me ētahi atu. Ko te nuinga o te wā ka whakamahia i roto i te moata sima me te whakahāngai i ngā hua gypsum. Ka whakamahia i roto i te moata sima hei whakanui ake i tōna piri, te ngāwari ki te mahi, te whakaiti i te rere o te wai, te whakapai ake i te matotoru me te whakaheke, me te pupuri i te wai, te whakaiti i te ngaronga wai i runga i te mata raima, te whakapai ake i te kaha, te ārai i ngā kapiti me te pirau o ngā tote wairewa-wai, me ētahi atu. He whānuitia te whakamahinga i roto i te parai sima, te parai gypsum, ngā hua gypsum, te parai kohatu, te whakakī rau, te whakakī, te piri taera, te rauemi papa whakaōrite-ake, me ētahi atu. Ka taea te whakamahi hei kaihanga kiriata, hei whakamātotoru, hei whakapūmau me te whakaū i roto i ngā paninga emulsion me ngā paninga kapia wairewa-wai, ka hoatu ki te kiriata he ātete pai ki te pakū, he ōrite me te piri, me te whakapai ake i te kukū o te mata, te pumau ki ngā waikawa me ngā turanga me te hototahi ki ngā tae whakarewa. Nā te pai o te pumau rokiroki matotoru, he tino pai hei whakamarara i roto i ngā paninga emulsified. I roto i te poto, ahakoa he iti te rahinga o roto i te pūnaha, he tino whai hua, he whānui hoki te whakamahinga.
Ko te pāmahana tiēre o te cellulose ether te mea e whakatau ana i tōna pumau wera i roto i ngā tono. Ko te pāmahana tiēre o te HPMC i te nuinga o te wā kei waenga i te 60°C ki te 75°C, i runga i te momo, te ihirangi rōpū, ngā tukanga whakaputa rerekē o ngā kaihanga rerekē, me ētahi atu. Nā ngā āhuatanga o te rōpū HEMC, he teitei te pāmahana tiēre, neke atu i te 80°C te nuinga. Nō reira, he teitei ake tōna pumau i raro i ngā āhuatanga pāmahana teitei i tērā o te HPMC. I roto i te mahi, i raro i te taiao hanga tino wera i te raumati, he nui ake te painga o te pupuri wai o te HEMC i roto i te moata ranunga mākū me te matotoru me te horopeta ōrite i te HPMC.
Ko te nuinga o te cellulose ether i roto i te umanga hanga o Haina ko te HPMC tonu, nā te mea he maha atu ngā momo me ngā utu iti iho, ā, ka taea te whiriwhiri noa i te utu whānui. I te whanaketanga o te mākete hanga o roto, inā koa te pikinga ake o te hanga miihini me te whakapainga o ngā whakaritenga kounga hanga, ka piki haere tonu te whakamahinga o te HPMC i roto i te mara hanga.
