1. Whakarōpūtanga:
HPMCKa taea te wehewehe ki te momo tere me te momo rewa-wera. Ka tere te marara o ngā hua momo tere i roto i te wai matao ka ngaro atu ki 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, ā, kāore he rewa tūturu. I muri i te 2 meneti pea, ka piki haere te matotoru o te wai hei hanga i te kōroiti matotoru mārama. Ko ngā hua rewa-wera, ina tūtaki ki te wai matao, ka taea te marara tere ki roto i te wai wera ka ngaro atu i roto i te wai wera. Ina heke te pāmahana ki tētahi pāmahana, ka puta mārire te matotoru kia puta rā anō he kōroiti matotoru mārama. Ka taea anake te whakamahi i te momo rewa-wera i roto i te paura putty me te moata. I roto i te kāpia wai me te peita, ka puta te āhuatanga piri, ā, kāore e taea te whakamahi. He whānui ake ngā tono o te momo tere. Ka taea te whakamahi i roto i te paura putty me te moata, tae atu ki te kāpia wai me te peita, me te kore he ārai.
2. Tikanga whakarewa:
Tikanga whakarewa wai wera: Nā te mea kāore te HPMC e whakarewa i te wai wera, ka taea te whakamarara ōrite i te HPMC ki te wai wera i te tīmatanga, kātahi ka tere te whakarewa i te wā e whakamatao ana. E rua ngā tikanga e whakaahuatia ana penei: 1), ringihia te nui e hiahiatia ana ki roto i te ipu wai wera, ka whakamahanahia ki te 70°C pea. I tāpirihia mārire te hydroxypropyl methylcellulose me te whakaoho puhoi, i te tuatahi ka mānu te HPMC ki runga i te mata o te wai, kātahi ka hanga mārire he paraoa pokepoke, ka whakamataohia me te whakaoho. 2), tāpirihia te nui e hiahiatia ana o te 1/3, 2/3 rānei o te wai i roto i te ipu, ka whakamahanahia ki te 70°C, e ai ki te tikanga 1), whakamararatia te HPMC, te whakarite i te paraoa pokepoke wai wera; kātahi ka tāpirihia te toenga o te wai matao ki te wai wera. I roto i te paraoa pokepoke, ka whakamataohia te ranunga i muri i te whakaoho.
Tikanga whakaranu paura: Whakaranua te paura HPMC me te nui o ētahi atu matū paura, whakaranua kia pai ki te mīhini whakaranu, kātahi ka tāpirihia he wai kia memeha, kātahi ka taea te memeha te HPMC i tēnei wā, me te kore e piri tahi, nā te mea he iti noa te HPMC o ia kokonga iti. Ka memeha tonu te paura ina pā ki te wai. ——Ka whakamahia tēnei tikanga e ngā kaihanga paura me te moata.Te Hydroxypropyl methylcellulose (HPMC)[e whakamahia ana hei whakamātotoru me te pupuri wai i roto i te moata paura putty]
