Tikanga Whakarewanga Hydroxyethyl Cellulose

Ko te Hydroxyethyl Cellulose (HEC) he pūmua wairewa-wai e whakamahia whānuitia ana hei whakamātotoru, hei emulsifier, hei whakaū, me ētahi atu.

Ngā Hipanga Whakarewanga Hydroxyethyl Cellulose

Whakaritea ngā rauemi me ngā taputapu:
Paura Hydroxyethyl Cellulose
Kaiwhakarewa (te nuinga o te wā he wai)
Pūrere whakaoho (pēnei i te whakaoho miihini)
Ngā taputapu ine (te rango ine, te pauna, me ētahi atu)
Ipu

Te whakamahana i te whakarewa:
Hei tere ake i te tukanga whakarewa, ka taea te whakamahana i te whakarewa kia tika, engari kaua e neke ake i te 50°C hei karo i te pirau wera pea. Ko te pāmahana wai i waenga i te 30°C me te 50°C te mea tino pai.

Tāpirihia mārire te paura HEC:
Āta tauhiuhia te paura HEC ki roto i te wai wera. Hei karo i te haaputuputu, tāpirihia mā te tātari, ata tauhiuhia rānei. Kia tino marara te paura HEC i te wā e whakaoho ana.

Me whakaoho tonu:
I te wā e whakaoho ana, me tāpiri haere tonu te paura HEC kia taurite te horapa o te paura ki roto i te wai. Kaua e tere rawa te whakaoho kia kore ai e pupuhi, e haaputuputu rānei. Ko te whakaoho tere waenga te tikanga e taunakihia ana.

Te whakarewatanga tū: I muri i te mararatanga katoa, me waiho mō tētahi wā (he maha ngā hāora, neke atu rānei) kia memeha katoa ai te HEC, kia hanga he otinga ōrite. Ko te wā tū ka whakawhirinaki ki te taumaha ngota o te HEC me te kukū o te otinga.

Te whakarerekē i te matotoru: Mena me whakarerekē te matotoru, ka taea te whakanui, te whakaiti rānei i te nui o te HEC. Hei tāpiri, ka taea hoki te whakarerekē mā te tāpiri i ngā irahiko, te whakarerekē i te uara pH, me ētahi atu.

Ngā whakatūpato i te wā e whakarewaina ana

Āraia te kohikohinga: He ngāwari te kohikohi i te Hydroxyethyl cellulose, nō reira, me aro nui ki te tauhiuhi ōrite i te wā e tāpirihia ana te paura. Ka taea te whakamahi i te tātari, i tētahi atu taputapu whakamarara rānei hei āwhina i te whakamarara ōrite.

Te pāmahana whakahaere: Kaua te pāmahana whakarewa e tino teitei rawa, ki te kore ka pakaru te HEC i roto i te wai, ā, ka pā ki te mahi a te otinga. He pai ake te whakahaere i waenga i te 30°C me te 50°C.

Āraia te hau kei uru: Kaua e whakaoho tere rawa kia kore ai te hau e uru ki roto i te wairewa, kia puta ai he mirumiru. Ka pāngia te ōritetanga me te māramatanga o te wairewa e ngā mirumiru.

Kōwhiria ngā taputapu whakaoho tika: Kōwhiria ngā taputapu whakaoho tika kia rite ki te matotoru o te wairewa. Mō ngā wairewa iti te matotoru, ka taea te whakamahi i ngā mea whakaoho noa; mō ngā wairewa nui te matotoru, me whakamahi pea i tētahi mea whakaoho kaha.

Te rokiroki me te tiaki:
Me rongoa te wairewa HEC kua rewa ki roto i tētahi ipu hiri hei ārai i te makuku, i te poke rānei. Mēnā ka rongoatia mō te wā roa, karohia te rā tika me te pāmahana tiketike hei whakarite i te pumau o te wairewa.

Ngā raruraru me ngā otinga noa
Te rewatanga kore taurite:
Ki te kore e ōrite te rewa, tera pea nā te tere rawa o te ruirui i te paura, nā te kore rānei i ranea te whakaoho. Ko te otinga he whakapai ake i te ōritetanga o te whakaoho, he whakanui ake i te wā whakaoho, he whakarerekē rānei i te tere o te tāpiri paura i te wā e whakaoho ana.

Te whakaputanga mirumiru:
Mena he nui ngā mirumiru e puta mai ana i roto i te wairewa, ka taea te whakaiti i ngā mirumiru mā te whakaiti i te tere o te whakaoho, mā te waiho rānei kia tū mō te wā roa. Mō ngā mirumiru kua puta kē, ka taea te whakamahi i tētahi kaihoko tango hau, te whakamahi rānei i te maimoatanga ultrasonic hei tango atu.

He nui rawa, he iti rawa rānei te matotoru o te otinga:
Ina kore te matotoru o te otinga e tutuki i ngā whakaritenga, ka taea te whakahaere mā te whakarerekē i te nui o te HEC. Hei tāpiri, mā te whakarerekē i te uara pH me te kaha ionic o te otinga ka pā ki te matotoru.

Ka taea e koe te whakarewa i te hydroxyethyl cellulose kia puta ai he otinga ōrite, pumau hoki. Mā te mōhio ki ngā mahi whakahaere tika me ngā whakatūpato ka taea te whakanui ake i te pānga o te hydroxyethyl cellulose i roto i ngā momo whakamahinga.
