Ka whakaroa te MHEC Cellulose Ether i te Tikanga Whakamakuku Sima
Metila Hauwaitoitirīti Hēroro (MHEC) he etera cellulose kore-ionic e whakamahia whānuitia ana i roto i ngā rauemi hanga, inā koa i roto i ngā hua sima. Ko tētahi o ana mahi nui i roto i ngā tono sima ko te whakaroa i te tikanga whakamakuku sima. He mea nui te mārama ki te huarahi e tutuki ai i te MHEC tēnei pānga hei whakapai ake i te mahi a ngā rauemi sima i roto i ngā kaupapa hanga.
Te Mārama ki te Whakamakuku o te Sima
He tauhohenga matū matatini te whakamakuku sima e puta ana ina tāpirihia te wai ki te sima. He mea nui tēnei tauhohenga mō te whakapakeketanga me te whanaketanga kaha o ngā rauemi sima, pērā i te raima me te moata. Kei roto i te tukanga te hanganga o ngā hua whakamakuku maha, tae atu ki te konupūmā silicate hydrate (CSH) me te konupūmā hydroxide, e whai wāhi ana ki te kaha me te roa o te rauemi.
Te Tūranga o te MHEC ki te Whakaroa i te Makuku o te Sima
He mea pupuri wai, he mea whakamātotoru hoki te mahi a te MHEC i roto i ngā rauemi sima. Ina tāpirihia ki te ranunga sima, ka rewa ki te wai, ka hanga he otinga korori e whai pānga ana ki te tukanga whakamakuku. Ko ngā huarahi matua e whakaroa ai te MHEC i te whakamakuku o te sima ko:
- Te Hanganga o tētahi Papa Tiaki
- TikangaKa piri ngā ngota MHEC ki te mata o ngā matūriki sima, ka hanga he paparanga tiaki. Ka whakaroahia e tēnei paparanga te urunga o te wai ki roto i ngā matūriki sima, ā, ka whakaroa i te tīmatanga o te tauhohenga waiwai.
- PāngaMā te whakaroa i te makuku tuatahi, ka taea e te MHEC te whakapai ake i te mahi me te roa ake o te wā tuwhera o te ranunga sima, he mea tino whai hua i roto i ngā tono pēnei i ngā piripiri taera, ina hiahiatia he wā mahi roa ake.
- TikangaMā ngā āhuatanga pupuri wai o te MHEC ka roa te pupuri i te makuku i roto i te ranunga sima. Mā tēnei tukunga puhoi o te wai ka tautokona te tukanga whakamakuku i roto i te wā.
- PāngaMā te whakamakuku whakahaere ka pai ake te whakamaroke, ka whakaiti i te tūponotanga o ngā pakaru me te mimiti i roto i te hua whakamutunga. Ka whakarei ake hoki tēnei i te kaha me te roa o te rauemi sima.
- TikangaKa whakanuia e te MHEC te matotoru o te ranunga sima, ka whakaroa i te nekehanga o te wai i roto i te ranunga. Ka whai wāhi atu tēnei pānga matotoru ki te whakaroa i te tukanga whakamakuku.
- PāngaMā te matotoru nui ake ka pai ake te mahi o te ranunga, ka māmā ake te pania, me te whakarite hoki kia āta haere, kia whakahaeretia hoki te tukanga whakamakuku.
- TikangaKo te whakaroa o te whakainu i puta mai i Mīhini ka pā ki te whanaketanga o te hanganga moroiti o te hanganga sima. Mā te puhoi o te tauhohenga ka taea te hanganga pai ake o ngā hua waikura, ka taea ai te whakapai ake i te kiato me te ōritetanga o te rauemi.
- PāngaMā te hanganga moroiti kiato ake, kia ōrite ake hoki, ka whakarei ake i ngā āhuatanga ā-pūkaha o te rauemi sima, tae atu ki tōna kaha pēhi me te ātete ki ngā āhuatanga taiao pēnei i te huringa tio-rewa.
Ngā Hua o te Whakaroa i te Wai Whakamakuku i roto i te Hanganga
He maha ngā painga o te whakaroa o te makuku o te sima e te MHEC i roto i ngā mahi hangahanga:
- Wā Mahi WhakaroaMā te MHEC ka roa ake te wā mahi, he mea nui tēnei mō ngā tono e hiahiatia ana te whakatakotoranga me te whakatikatika tika o ngā rauemi, pērā i ngā piripiri taera me ngā pāreti.
- Te Whakarei Ake i te Āhua MahiKo te matotoru me te pupuri wai kua whakarei ake i whakaratohia e Mīhini kia māmā ake te whakahaere me te whakamahi i te ranunga sima, kia pai ake ai te whai huatanga o te hanganga whānui.
- Te Whakaiti i te Mōrearea o te PakaruMā te whakahaere i te tere o te makuku me te whakarite kia rite te whakamaroke, Mīhini ka āwhina ki te whakaiti i te tūponotanga o te mimiti me te ngatata, ka hua ake he hanganga pakari ake.
- Te Pumautanga WhakareiKo te hanganga moroiti kua whakapaitia mai i te tukanga whakamakuku whakahaeretia ka whai wāhi ki te roa o te mau me te kaha o ngā rauemi sima.
