Kāore e tino wairewa te Hydroxypropyl methylcellulose i roto i te etanoru tino me te acetone. He tino pumau te wairewa i te pāmahana rūma, ā, ka taea te whakapūmau i te pāmahana teitei. Ko te nuinga o te hydroxypropyl methylcellulose kei te mākete ināianei he momo wai matao (wai pāmahana rūma, wai puna). He watea ake, he haumaru ake hoki te whakamahi i te HPMC wai matao. Me tāpiri tika te HPMC ki te wai matao i muri i te tekau ki te iwa tekau meneti kia mātotoru haere. Mena he tauira motuhake, me whakaoho ki te wai wera kia marara, kātahi ka ringihia ki te wai matao kia memeha i muri i te whakamatao.
Ina tāpirihia tika ngā hua HPMC ki te wai, ka rewa, kātahi ka memeha, engari he tino puhoi, he uaua hoki tēnei memeha. E toru ngā tikanga memeha e tūtohutia ana, ā, ka taea e ngā kaiwhakamahi te whiriwhiri i te tikanga tino watea i runga i te whakamahinga (ko te nuinga mō te HPMC wai matao tonu).
Te tikanga whakarewa me ngā mahi ārai o te HPMC
1. Tikanga wai matao: Mēnā me tāpiri tika ki te wairewa wai pāmahana noa, he pai ake te whakamahi i te momo marara wai matao. Whai muri i te tāpiri i te matotoru, ka piki haere te matotoru ki te taumata e hiahiatia ana.
2. Tikanga whakaranu paura: Ka marara katoatia te paura HPMC me te nui ōrite, neke atu rānei o ētahi atu wāhanga paura mā te whakaranu maroke, ā, i muri i te tāpiri wai hei whakarewa, ka taea te whakarewa i te HPMC i tēnei wā, ā, kāore e memeha haere. Inaa, ahakoa te momo hydroxypropyl methylcellulose. Ka taea te whakaranu maroke tika ki ētahi atu rauemi.
3. Tikanga whakamakuku whakarewa waro: Ka whakamararatia, ka whakamakukuhia rānei te HPMC ki ngā whakarewa waro, pērā i te etanoru, te ethylene glycol, te hinu rānei, kātahi ka rewa ki te wai, ā, ka taea hoki te rewa maeneene i te HPMC.
I te wā e whakarewahia ana, ki te mea he puranga, ka takaihia. Koinei te hua o te whakaoho kore taurite, nō reira me tere ake te whakaoho. Mena he mirumiru kei roto i te whakarewa, nā te hau i puta mai i te whakaoho kore taurite, ā, me waiho te otinga kia tū mō te 2-12 hāora (ko te wā motuhake e whakawhirinaki ana ki te matotoru o te otinga) mā te whakamahi i te mīhini horoi, te pēhanga me ētahi atu tikanga hei tango, mā te tāpiri i te nui o te whakakore pahuka e tika ana ka taea hoki te whakakore i tēnei āhuatanga. Mā te tāpiri i te nui o te whakakore pahuka e tika ana ka taea hoki te whakakore i tēnei āhuatanga.
I te mea e whakamahia ana te hydroxypropyl methylcellulose i roto i ngā ahumahi maha, he mea nui kia mōhio ki te tikanga whakarewa o te hydroxypropyl methylcellulose kia tika ai te whakamahinga. Hei tāpiri, me aro ngā kaiwhakamahi ki te tiaki i te rā, te tiaki i te ua me te tiaki i te makuku i te wā e whakamahia ana, me karo i te mārama tika, me te penapena ki te wāhi hiri me te maroke. Me karo i te pa atu ki ngā pūtake mura, me te karo i te hanganga o te nui o te puehu i roto i ngā taiao kati hei ārai i ngā tūponotanga pahūtanga.
