3. Tikanga whakamahi
Tikanga whakarewa
Tikanga whakamarara wai matao: Tauhiuhia mārire te HPMC ki roto i te wai matao, whakaohokia tonu kia marara ōrite, kātahi ka whakamahana ki te 30-60℃ ka memeha rawa.
Tikanga whakarewa wai wera: tuatahi whakamakukuhia te HPMC ki te wai wera (neke atu i te 60°C) kia pupuhi, kātahi ka tāpirihia he wai matao ka whakaoho kia memeha.
Tikanga whakaranu maroke: tuatahi whakaranua te HPMC me ētahi atu paura maroke, kātahi ka tāpirihia he wai ka whakaoho kia memeha.
Te nui o te tāpiri
I roto i te umanga hanga, ko te nui o te HPMC e tāpirihia ana i te nuinga o te wā ko te 0.1%-0.5%.
I roto i ngā umanga kai me te rongoā, ka whakarerekētia te nui o te tāpiri kia rite ki te kaupapa motuhake.
4. Ngā whakatūpato mō te whakamahinga
Ngā tikanga rokiroki
Penapena ki te wāhi hauhautanga, maroke, pai te hauhautanga, kia kore ai e pā ki te makuku me te rā tika.
Puritia kia matara atu i ngā pūtake wera, i ngā pūtake ahi me ngā waikura kaha hei ārai i te pirau me te tahunga.
Ngā whakatūpato mō te whakarewatanga
Kaua e tāpirihia he nui o te HPMC i te wā kotahi hei ārai i te hanganga o ngā puranga, ā, ka pā ki te pānga whakarewa.
He puhoi te tere whakarewa i te taiao pāmahana iti, ā, ka taea te whakanui ake i te pāmahana kia tika, te whakaroa rānei i te wā whakaoho.
Te haumaru o te whakamahinga
He matū kore paitini, kore kino hoki te HPMC, engari ka pāngia pea e te hau ina manawahia ana i te āhua paura, nō reira me karo i te nui o te puehu.
E taunaki ana kia mau i te kopare kanohi me ngā mōhiti kanohi i te wā e hanga ana hei karo i te whakapataritari puehu ki te ara manawa me ngā kanohi.
Hototahitanga
I te wā e whakamahia ana, kia tūpato ki te hototahitanga me ētahi atu matū, inā koa i te wā e whakarite ana i ngā rauemi hanga, i ngā rongoā rānei, me whakamātautau hototahi.
I te ao kai me te rongoā, me tutuki ngā ture me ngā paerewa e tika ana kia noho haumaru ai.
Hydroxypropyl methylcelluloseHe whānuitia te whakamahinga i roto i ngā ahumahi maha nā tōna mahi tino pai. I te wā e whakamahia ana, me mātau ki te tikanga whakarewa tika me ngā pūkenga whakamahi, me te aro ki ngā take rokiroki me te haumaru kia mau ai te pumau me te mahi a te hua. Mā te whakamahinga tika o te HPMC, ehara i te mea ka taea anake te whakapai ake i te kounga o te hua, engari ka whakapai ake hoki i te whai huatanga o te hanganga me te whakaputa.
