He tāpiri noa te cellulose ether i roto i ngā rauemi hanga, e whakamahia ana hei whakarei ake i te mahi hanga me ngā āhuatanga hangarau o te moata. Ko te pai o te hanganga tētahi o ngā āhuatanga nui o te cellulose ether, e pā ana ki tōna tohatoha rahi matūriki.
Ngā āhuatanga me ngā whakamahinga o te cellulose ether
Ko te nuinga o ngā mea kei roto i te cellulose ether ko te hydroxypropyl methylcellulose (HPMC), te hydroxyethyl cellulose (HEC), me ētahi atu. Ko ā rātou mahi matua i roto i te hanga moata ko:
Te pupuri wai: mā te whakaiti i te mimiti wai, te whakaroa i te wā makuku o te sima, me te whakapakari i te kaha o te moata.
Te Whakamātotoru: Ka whakanui ake i te matotoru o te moata, ka whakapai ake hoki i te mahi hanga.
Whakapai ake i te ātete ki ngā pakaru: Mā te āhuatanga pupuri wai o te cellulose ether ka āwhina i te whakahaere i te mimiti o te sima, ā, ka whakaitihia te puta o ngā pakaru i roto i te moata.
Ka pā te mātotoru o te cellulose ether ki tōna mararatanga, tōna wairewatanga me tōna whai huatanga i roto i te moata, ā, ka pā ki te mahi whānui o te moata.
Ka taea te tātari i te pānga o te pai o te cellulose ether ki te kaha o te moata mai i ngā āhuatanga e whai ake nei:
1. Te tere whakarewa me te horapa
He hononga tata te tere whakarewa o te cellulose ether i roto i te wai ki tōna āhua pai. Ko ngā matūriki cellulose ether he pai ake te āhua pai ka ngāwari ake te whakarewa ki te wai, ā, ka tere te hanga i tētahi marara ōrite. Mā tēnei tohatoha ōrite ka taea te whakarite i te pupuri wai pumau me te matotoru i roto i te pūnaha moata katoa, te whakatairanga i te ahunga whakamua ōrite o te tauhohenga whakamakuku sima, me te whakapai ake i te kaha wawe o te moata.
2. Te kaha pupuri wai
Ka pā te pai o te cellulose ether ki tōna mahi pupuri wai. Ko ngā matūriki cellulose ether he pai ake te pai ka whakarato i te horahanga mata motuhake, ā, ka hangaia he hanganga moroiti pupuri wai i roto i te moata. Ka taea e ēnei moroiti te pupuri wai, te whakaroa i te wā tauhohenga whakamakuku sima, te whakatairanga i te hanganga o ngā hua whakamakuku, ā, nā reira ka whakarei ake i te kaha o te moata.
3. Te hononga atanga
Nā te pai o te horapa o ngā matūriki cellulose ether, he pai ake te matotoru, ka taea te hanga i tētahi paparanga hononga ōrite i waenga i te moata me te konganuku, ā, ka whakapai ake i te hononga o te moata. Mā tēnei pānga ka āwhina i te moata kia mau tonu te kirihou i te wā tōmua, ka whakaiti i te puta o ngā kapiti mimiti, ā, ka whakapai ake i te kaha whānui.
4. Te whakatairanga i te whakamakuku sima
I te wā e whakamakuku ana i te sima, me nui te wai hei hanga i ngā hua whakamakuku. Ka taea e te cellulose ether he pai ake te hanga i ngā āhuatanga whakamakuku ōrite i roto i te moata, ka karo i te raruraru o te koretake, te nui rawa rānei o te makuku ā-rohe, ka whakarite i te ahunga whakamua katoa o te tauhohenga whakamakuku, ā, ka whakapai ake i te kaha o te moata.
Te rangahau whakamātautau me te tātari hua
Hei manatoko i te pānga o te pai o te cellulose ether ki te kaha o te moata, i whakatikatikaina e ētahi rangahau whakamātautau te pai o te cellulose ether, ā, i whakamatauria ōna āhuatanga hangarau o te moata i raro i ngā ōwehenga rerekē.
Hoahoa whakamātautau
Ko te tikanga, ka whakamahia e te whakamātautau ngā tauira cellulose ether o ngā momo matotoru rerekē, ka tāpirihia ki te moata sima. Mā te whakahaere i ētahi atu taurangi (pēnei i te ōwehenga wai-sima, te ōwehenga whakakotahi, te wā whakaranu, me ētahi atu), ko te matotoru anake o te cellulose ether ka whakarerekētia. Kātahi ka whakahaerehia he raupapa whakamātautau kaha, tae atu ki te kaha pēhi me te kaha piko.
Ko ngā hua o te whakamātautau e whakaatu ana i te nuinga o te wā:
Ka taea e ngā tauira cellulose ether he pai ake te whakanikoniko te whakapai ake i te kaha pēhi me te kaha piko o te moata i te wā tōmua (pērā i te 3 rā me te 7 rā).
Mā te whakaroa i te wā whakamaroke (pēnei i te 28 rā), ka taea tonu e te cellulose ether he pai ake te ātaahua te pupuri i te wai me te here, e whakaatu ana i te tipu kaha pumau.
Hei tauira, i roto i tētahi whakamātautau, ko te kaha pēhi o ngā etera cellulose me te matotoru o te 80 mata, 100 mata, me te 120 mata i roto i ngā rā 28 he 25 MPa, 28 MPa, me te 30 MPa. E whakaatu ana tēnei ko te teitei ake o te matotoru o te etera cellulose, ko te nui ake o te kaha pēhi o te moata.
Te whakamahinga whai hua o te arotautanga o te pai o te cellulose ether
1. Whakarerekētia kia rite ki te taiao hangahanga
Mēnā he hanga i roto i te taiao maroke, i raro rānei i ngā āhuatanga pāmahana tiketike, ka taea te whiriwhiri i te cellulose ether he tino pai ake te matotoru hei whakapai ake i te pupuri wai o te moata me te whakaiti i te ngaronga kaha e puta mai ana i te mimiti wai.
2. Whakamahia me ētahi atu tāpiringa
Ka taea te whakamahi i te cellulose ether he pai ake te matotoru me ētahi atu tāpiringa (pēnei i ngā mea whakaiti wai me ngā mea whakauru hau) hei whakapai ake i te mahi a te moata. Hei tauira, mā te whakamahi i ngā mea whakaiti wai ka taea te whakaiti i te ōwehenga wai-sima me te whakanui ake i te mātotoru o te moata, ko te cellulose ether ia ka whakarato i ngā pānga pupuri wai me te whakapakari. Mā te whakakotahitanga o ngā mea e rua ka taea te whakapai ake i te kaha o te moata.
3. Te arotau i te tukanga hanga
I te wā o te hanga, me whakarite kia rewa katoa te cellulose ether, kia marara katoa hoki. Ka taea tēnei mā te whakanui ake i te wā whakaranu, mā te whakamahi rānei i ngā taputapu whakaranu tika hei whakarite kia tino whakamahia te painga o te pai o te cellulose ether.
He pānga nui te pai o te cellulose ether ki te kaha o te moata. Ka taea e te cellulose ether he pai ake te pupuri i te wai, te whakamātotoru me te whakapai ake i te hononga o te atanga, me te whakapai ake i te kaha wawe me ngā āhuatanga miihini roa o te moata. I roto i ngā mahi whaihua, me whiriwhiri tika te pai o te cellulose ether me te whakamahi i runga i ngā tikanga me ngā whakaritenga hanga motuhake hei whakapai ake i te mahi moata me te whakapai ake i te kounga o te kaupapa.
