Ko te cellulose ether he momo pūhui pūmua i whiwhihia mā te whakarerekētanga matū o te cellulose tūturu, he tino pai te wairewa, te matotoru, te pupuri wai me ngā āhuatanga hanga kiriata. Ko ngā momo cellulose ether noa kohydroxypropyl methylcellulose (HPMC), methylcellulose (MC), te hauwaitoiretira o te pūtau (HEC), te hauwaitoireti metiretira (HEMC), me ētahi atu. E whakamahia whānuitia ana ēnei i roto i ngā rauemi hanga, inā koa i roto i ngā pūnaha moata maroke-ranu.
1. Te tikanga mahi a te cellulose ether i roto i te moata
I roto i ngā tātai moata hou, ko te cellulose ether, hei tāpiri matū matua, ka whai wāhi nui ki ēnei āhuatanga:
1.1. Te pupuri wai pai ake
He nui ngā rōpū hydrophilic o ngā ngota cellulose ether, ka taea te mimiti me te raka i te wai kore utu, te whakaroa i te mimiti me te urunga o te wai, te tuku i te wai kia uru katoa ki te tauhohenga whakamakuku sima, me te whakapai ake i te whai huatanga o te hanganga kaha wawe. Ina hangaia ana i runga i ngā papa he kaha te mimiti wai (pēnei i te raima hau, ngā pereki), ka taea e te cellulose ether te aukati i te mimiti nui o te wai me te karo i te pakaru me te paura.
1.2. Te whakamātotoru me te whakapai ake i te mahi hanga
Ka taea e te cellulose ether te whakapai ake i te matotoru me te thixotropy o te moata, kia pai ai te rere me te mahi hanga o te moata i te wā e whakaranua ana, e pania ana hoki, engari he nui ngā āhuatanga piri me te ārai-paheke i roto i te āhua pumau, kia pai ake ai te maeneene o te hanga me te whakaiti i te totohu.
1.3. Te whakapai ake i te kaha o te hononga
Mā te whakarei ake i te piripono o te moata me te mahi here ā-kanohi ki te papa, ka whakapai ake te cellulose ether i te kaha here o te moata, ka karo i ngā raruraru pēnei i te wehewehe me te poka i te wā o muri mai, ā, he tino pai mō ngā piripiri taera, ngā moata whakataurite-ake me ngā pūnaha whakamahana o waho.
1.4. Te whakaroa i te wā whakatakoto me te whakapai ake i te whakahaeretanga
Ka taea e te cellulose ether te whakaroa i te wā tuwhera o te moata, kia nui ake ai te wā o ngā kaimahi ki te whakarerekē me te kuti i te wā hanga, me te karo hoki i ngā hapa hanga e puta mai ana i te maroke wawe.
2. Te whakamahinga o te cellulose ether i roto i ngā momo moata rerekē
2.1. Te whakapūtātanga o te moata
Mā te tāpiri i te cellulose ether ki te moata parai ka pai ake te piri i waenga i te moata me te pakitara, ā, ka ārai i ngā raruraru pēnei i te "pōkarekare me te ngatata". Mā te pupuri pai i te wai ka taea hoki te whakarite kia maroke ōrite te paparanga pungarehu, ā, ka pai ake te pānga whakaoti.
2.2. Piripiri Tāera
He nui ngā āhuatanga pupuri wai me te ārai-paheke e hiahiatia ana mō ngā piripiri taera. Ka taea e te cellulose ether te whakapai ake i tōna kaha piri, te ārai i ngā taera kei paheke ki raro, me te whakarite i te pānga piri pai ki te tuara o ngā taera he iti te mimiti wai.
2.3. Moata whakaōrite-ake
Ka whakaratohia e te cellulose ether te ōritetanga me te pupuri wai e tika ana i roto i te moata whakataurite-ake kia rite ai te whakatakotoranga me te kore he raruraru kounga pēnei i te toto me te ngatata. He tino pai ngā momo cellulose ether iti-matotoru mō ēnei mahi.
2.4. Moata whakamātao (pūnaha EIFS)
I roto i te pūnaha whakamarumaru pakitara o waho, ka tāpirihia te cellulose ether ki te moata honohono me te moata ārai-ngatata hei whakapai ake i te ātete ki te ngatata, hei whakanui ake i te kaha o te honohono, me te whakapai ake i te roa me te pumau o te pūnaha whānui.
2.5. Moata pereki maroke-whakaranu
He maha ngā wā ka whakamahia te moata pereki maroke-whakaranu hei hanga pereki. Ka taea e te cellulose ether te whakapai ake i tōna kaha papu, te pupuri wai me te ārai i te totohu, te hanga i te moata kia ōrite me te kī, me te whakapai ake i te kiato me te kaha pēhi o te pereki.
3. Ngā āhuatanga e pā ana ki te mahi
He pānga nui tō te mahi a te cellulose ether ki te mahi whakamutunga o te moata, tae atu ki ēnei āhuatanga:
Teitei o te matotoru: He pai te cellulose ether matotoru-teitei mō ngā moata e hiahia ana ki ngā āhuatanga ātete-paheke teitei, ko te matotoru iti ia he pai mō ngā hua whakataurite-ake.
Te nui o te whakakapinga (DS) me te whakakapinga molar (MS): Mā ēnei tawhā e rua ka whakatau te wairewatanga, te pupuri wai me te pumau o te cellulose ether.
Rahi o te matūriki: He māmā ake te whakamarara i te paura angiangi ki roto i te moata, ka pai ake te ōritetanga whānui.
Te tere whakarewa: Mā te cellulose ether e tere whakarewa ana ka pai ake te whai hua o te whakaputa me te whai hua o te whakaranu.
4. Ngā taunakitanga whakamahinga me ngā whakatūpato
Kōwhiria te matotoru me te momo cellulose ether e tika ana kia ōrite ki ngā whakaritenga motuhake o te pūnaha moata.
Me whakarite te tukanga whakaranu kia ōrite te marara o te cellulose ether kia kore ai e pāngia te mahi e te kohikohinga ā-rohe.
Whakahaerehia te nui o te tāpiri, ko te tikanga 0.1%-0.5% o te taumaha o te sima. Tērā pea ka pāngia te kaha me te wā maroke e te nui rawa.
Me aro nui ki ngā whakamātautau hototahi ina whakamahia tahitia me ētahi atu tāpiringa (pēnei i te paura rapa ka taea te whakamarara anō, te kaihoko whakaiti wai, me ētahi atu).
Hei tētahi o ngā tāpiri matua i roto i te moata maroke-ranu hou,He mahi nui tā te cellulose ether i roto i te mahi hangahanga, ngā āhuatanga miihini me te pakari. I te whanaketanga o ngā whare matomato me ngā whare kua oti te hanga, kei te tipu haere tonu te hiahia mō te moata mahi-teitei, ā, kei te arotau tonuhia hoki ngā momo me ngā hangarau o te cellulose ether. Mā te whiriwhiringa whaitake me te whakamahinga pūtaiao o te cellulose ether ka tino whakapai ake i te kounga o ngā hua moata me te whai huatanga o te hanga, he huarahi nui tēnei mō te whanaketanga o ngā rauemi hanga o nāianei.
