Ka taea te wehewehe i te HPMC ki te tere (te tohu waitohu "S") me te wairewa wera. Ko ngā hua tere ka tere te marara i roto i te wai matao, ka ngaro i roto i te wai, i tēnei wā kāore he matotoru o te wai, nā te mea ka marara noa te HPMC i roto i te wai, kāore he memehatanga tūturu. Tata ki te 2 meneti, ka piki haere te matotoru o te wai, ka hanga he tiēre mārama, piri. Ko ngā hua wairewa wera, ka puranga i roto i te wai matao, ka tere te marara i roto i te wai wera, ka ngaro i roto i te wai wera, pērā i te hekenga o te pāmahana ki tētahi pāmahana (e ai ki te pāmahana tiēre o te hua), ka puta mārire te matotoru, tae noa ki te hanganga o te colloid matotoru mārama.

(1) Ko te pupuri wai o te methyl cellulose e whakawhirinaki ana ki te nui o te tāpiri, te matotoru, te pai o te matūriki me te tere whakarewa. I te nuinga o te wā, he nui te nui o te tāpiri, he iti te pai, he nui te matotoru, he teitei te tere pupuri wai, he nui te pānga o te nui tāpiri ki te tere pupuri wai, kāore te matotoru me te tere pupuri wai i raro i te whanaungatanga, ko te tere whakarewa e whakawhirinaki ana ki te nui o te whakarerekētanga mata me te pai o te matūriki o ngā matūriki cellulose. Ko te methyl cellulose me te hydroxypropyl methyl cellulose i roto i ngā cellulose ethers kua whakahuatia ake nei he tere pupuri wai teitei ake.
(2) Ka taea te rewa i te methyl cellulose ki te wai matao, engari he uaua ki te rewa i te wai wera, he tino pumau te wairewa i roto i te awhe pH = 3-12, ā, he pai te hototahi o te māngaro me ētahi atu, me te maha o ngā surfactants, ina tae te pāmahana ki te pāmahana gelation, ka puta he āhuatanga gelation.
(3) Ka pā kino ngā panonitanga pāmahana ki te tere pupuri wai o te methyl cellulose, i te nuinga o te wā, ka kino ake te pupuri wai. Mēnā ka neke ake te pāmahana o te moata i te 40 nekehanga, ka kino rawa atu te pupuri wai o te methyl cellulose, ka pā kino ki te hanganga o te moata.
(4)Mītirau pūtauHe mārama te pānga ki te hanganga me te piri o te moata. Ko te piri i konei e pā ana ki te kaha piri e pā ana ki te kaimahi i waenga i te taputapu me te papa pakitara, arā, ko te ātete kutikuti o te moata. He nui te piri, he nui te ātete kutikuti o te moata, he nui hoki te kaha e hiahiatia ana e ngā kaimahi i te wā e whakamahia ana, ā, he ngoikore te hanganga o te moata.
