Hydroxypropyl Methylcellulose Kua Whakarerekētia (HPMC Kua Whakarerekētia)He tāpiringa pūmua nui te Pēneti i roto i ngā rauemi hanga, inā koa i roto i ngā pūnaha moata hanga. Ka arotau ake anō i te mahi a te HPMC mā roto i ngā tikanga ā-tinana, ā-matū rānei, kia pai ake ai te mahi hanga, te pupuri wai, te ārai-totoka me ngā āhuatanga piri i roto i ngā kaupapa hanga.
1. Te tikanga mahi a te HPMC kua whakarerekētia
He etera cellulose kore-ionic te HPMC whakarerekētia. He pumau i roto i te taiao kawakore, ā, he pai te wairewa me te marara mā te whakakapinga o ngā rōpū hydroxypropyl me te methyl ki te angaanga cellulose. Ko te maimoatanga whakarerekētanga ko:
Te maimoatanga mata (hei tauira: te tauhohenga whakaetere, te whakapai ake i te wairewatanga tere, te marara rānei);
Tauhohenga honohono (te whakarei ake i te ōritetanga me te pupuri wai);
Te whakarerekētanga ā-wai (te whakapai ake i te ātete ki te totohu me te ātete ki te wai);
Maimoatanga tauhohenga wera (te whakahaere i te pāmahana tiēre kia tutuki ai ngā whakaritenga hanga), me ētahi atu.
Mā ēnei tikanga whakarerekētanga, he māmā ake te whakamarara i te HPMC ki roto i te moata hei hanga i tētahi otinga colloidal ōrite, ka taea ai te whakarerekē i ngā āhuatanga rheological, te pupuri wai me ngā āhuatanga ārai-totoka o te moata.
2. Te tūranga matua o te HPMC kua whakarerekētia i roto i te hanga moata
2.1. Te whakapai ake i te pupuri wai
Ka hangaia e te HPMC whakarerekētia he hanganga whatunga toru-ahu i roto i te moata, ka ārai i te ngaronga o te wai. He mea tino nui tēnei āhuatanga i roto i te tukanga whakamakuku sima, ka taea ai te whakarite kia tino makuku te sima, ka whakaiti i te tūponotanga o te mimiti me te ngatata, me te whakapai ake i te kaha o muri mai. He mea tino nui mō te hanganga i roto i ngā taiao pāmahana teitei me te maroke.
2.2. Whakapai ake i te mahi hanga
He tino pai te whakahinuhinu me te whakamātotoru o te HPMC kua whakarerekētia, ā, ka māmā ake te pani me te waru i te moata i muri i te whakaranu, ka whakaiti i te ātete o ngā taputapu hanga, ā, ka whakapai ake i te whai huatanga o te hanga. He tino pai mō te rehu mīhini moata, ka whakapai ake i te kaha o te papu me te whakahaere.
2.3. Whakapai ake i te mahi ārai-totoka
He mea nui te mahi ārai-heke mō ngā pūnaha hanga mata o mua pērā i ngā piri taera me ngā moata paraikete. Ka taea e te HPMC kua whakarerekētia te whakapai ake i te matotoru me te thixotropy, kia pai ai te pumau o te moata i roto i te āhua tūmau, kia kore ai e paheke i muri i te paninga, ā, kia pai ai te kounga o te hanganga.
2.4. Whakapai ake i te piri me te hononga
Ka taea e te HPMC kua whakarerekētia te whakapai ake i te piri i waenga i te moata me ngā rauemi pēnei i te turanga me ngā taera. Nā ōna āhuatanga hanga kiriata ka taea te hanga i tētahi paparanga kiriata ngāwari ki runga i te mata o te moata, ka whakarei ake i te kaha o te hononga ā-mata. I taua wā anō, ka whakapai ake i te piri whānui o te moata hei ārai i te pakaru me te wehewehe.
2.5. Whakatikatika i te ōritetanga me te rere o te wai
He rerekē ngā whakaritenga mō te matotoru o te moata i ia tukanga hanga. He momo thixotropy tō te HPMC kua whakarerekētia, e āhei ai te moata ki te pupuri i te rere pai i raro i te taumahatanga, ā, ka tere te whakahoki mai i te matotoru ina tū tonu, e tutuki ai ngā whakaritenga hanga rerekē pērā i te parai, te whakataurite, me te whakapiripiri.
3. Ngā tono motuhake i roto i ngā moata hanga rerekē
3.1. Moata piripiri tāera
Ka taea e te HPMC kua whakarerekētia te whakapai ake i te ātete-paheke me te pupuri wai o ngā piripiri taera, me te whakarei ake i te kaha piri o ngā taera rahi. Ina koa i roto i te hanganga angiangi, ka whakarite i te ngāwari o te hanganga me te pakari o te piri.
3.2. Te whakapūtātanga o te moata
I roto i te moata parai, ka whakapai ake te HPMC kua whakarerekētia i te mahi, ka whakaiti i ngā raruraru poka me te ngatata i puta mai i te mimiti tere o te wai, ā, ka whakarite kia maeneene, kia ngawari hoki te mata. He pai hoki mō te moata rehu mīhini hei whakapai ake i te pai o te papu.
3.3. Moata papa me te moata whakataurite-ake
He nui ngā whakaritenga mō te rere o te mata i te whakataurite-ake. Mā te HPMC kua whakarerekētia ka whakaratohia he rere e tika ana me te kore e ngaro te kaha, me te whakahaere anō hoki i te wehenga wai me te whakapai ake i te kounga o te mata me te papatahi i muri i te whakatakotoranga.
3.4. Whakatikatika i te moata
Mō ngā whakatikanga moroiti me ngā paparanga angiangi, ka taea e te HPMC kua whakarerekētia te whakapai ake i te kaha o te here i waenga i te moata me te paparanga turanga, te whakaiti i te mōrearea o te wehewehe me te paura i te wāhanga o muri mai, ā, he pai mō te hanga whakatikanga taipitopito o ngā pakitara, piriti, me ētahi atu.
4. Ngā tūtohutanga mō te horopeta me te kōwhiringa o te HPMC kua whakarerekētia
I roto i ngā tātai tūturu, ko te nui o te HPMC whakarerekētia i tāpirihia ko te 0.2%~0.6% (i runga i te taumaha katoa o te paura maroke), ā, me whakatau te nui motuhake i runga i te momo moata, te taiao hanga me ngā whakaritenga mahi.
Ngā whakaritenga pupuri wai teitei: tīpakohia te HPMC kua whakarerekētia me te tohu whakakapinga teitei me ngā matūriki pai;
Teitei te ātete-totoru: tīpakohia te matotoru teitei, te HPMC whakarerekētia thixotropic;
Pūnaha whakaōrite-ake, pūnaha papa rānei: tīpakohia te HPMC whakarerekētia he matotoru iti, he rere teitei;
Ngā whakaritenga whakarewatanga inamata (moata kua whakaranua): tīpakohia te HPMC whakarerekētanga inamata kua maimoatia ki te mata.
He mahi nui tā te HPMC kua whakarerekētia ki te hanga moata, inā koa ki te whakapai ake i te pupuri wai, te mahi hanga, te piri me te mahi ārai-totoka. Ehara i te mea ka arotau noa i ngā āhuatanga miihini me ngā pānga hanga o te moata, engari ka whakarato hoki i te turanga rauemi pakari mō ngā hangarau hanga hou (pēnei i te rehu miihini, te hanga kiriata angiangi, me te papa whakahāngai-ake). I te heke mai, me te whanaketanga o ngā rauemi hanga matomato me ngā rauemi hanga mahi-teitei, ka whānui ake, ka whai hua ake te whakamahinga o te HPMC whakarerekētia i roto i te mara o te moata hanga.
