Whakaiti wai Polycarboxylate(PCE)He whakatupuranga hou tēnei o te whakaiti wai tino whai hua, ā, he whānui rawa te whakamahinga me te mahi pai rawa atu i roto i ngā rauemi sima o nāianei. He whānui te whakamahinga i roto i te raima kua oti te whakaranu, te moata whakataurite-ake, ngā rauemi whakatō, te moata whakatika me te raima tino mahi.
1. Tikanga mahi
Ko te whakaiti wai polycarboxylate he momo surfactant ngota-teitei e tohuhia ana e ngā mekameka taha polyether me ngā mekameka matua waikawa carboxylic. Ko ōna kaha ki te whakaiti me te horapa i te wai e ahu mai ana i ngā āhuatanga e rua:
1.1. Te ātete hikohiko
Kei roto i te mekameka matua o te ngota whakaiti wai Polycarboxylate he maha o ngā rōpū carboxyl (-COOH), ka whaka-ionihia i roto i te taiao kawakore hei hanga i ngā radical carboxylate (-COO⁻), ka piri ki te mata o ngā matūriki sima, ka mau te utu kino kotahi i ngā matūriki, ka panaia tetahi ki tetahi, ka whakatairanga i te marara o ngā matūriki sima.
1.2. Te pānga aukati pākia
Mā ngā mekameka taha polyether pērā i ngā rōpū polyoxyethylene (PEO) ka ārai i te kohikohinga anō o ngā matūriki sima mā te aukati steric, ā, ka whakanui ake i te pakari o te mararatanga. He pai ake tēnei āhuatanga i ngā mea whakaiti naphthalene me te wai aliphatic tuku iho.
2. Te tūranga matua i roto i te moata sima
2.1. Whakapai ake i te rere o te wai
Mā te pupuri i te ōwehenga wai-sima kāore i rerekē, ka taea e te PCE te whakapai ake i te rere o te moata, kia māmā ake ai te hanga me te horapa ōrite, he mea tino pai mō te moata whakataurite-ake me ngā rauemi whakakī.
2.2. Whakaitihia te whakamahinga wai
Ka taea e te PCE te whakaiti i te wai whakaranu mā te 20%-35% pea, me te kore e pā ki te rere o te wai, ā, ka whakapai ake i te mātotoru me te kaha o te moata, ka whakapai ake hoki i te roa o te ora.
2.3. Whakapai ake i te pupuri wai me te mahi hanga
Mā te tohatoha ōrite i ngā matūriki sima, ka taea e te PCE te whakaiti i te turuturu me te wehewehenga o te wai, ka pumau ake te moata, ka pai ake ai te tiaki me te whakawhanake i te kaha i muri mai.
2.4. Whakatairanga i te tauhohenga whakamakuku sima
Mā te whakaiti i te kohikohinga o ngā matūriki sima, me te tuku kia tino pā ki te wai, ka āwhina i te ōritetanga o te tauhohenga waiwai me te tipu wawe o te kaha o te moata.
2.5. Whakapai ake i ngā āhuatanga ā-pūkaha
Nā te tere whakaheke wai nui me te hanganga kiato, he nui ake te kaha pēhi me te kaha piko o te moata sima i konatunatua ki te PCE, inā koa i roto i te moata kaha-teitei.
3. Ngā painga mahi
Te whakaiti wai tino whai hua: Ki te whakatauritea ki ngā whakaiti wai tuku iho e hangai ana ki te naphthalene me te lignin, he nui ake te tere whakaiti wai o te PCE, ā, he pumau ake tana mahi.
He iti te horopeta me te mahi nui: Ko te nuinga o te wā ko te horopeta he 0.1% -0.3% noa iho o te rauemi sima, ka taea te whakatutuki i te pānga whakaiti wai pai rawa atu.
Hototahi pai: Ka taea te whakakotahi me te maha o ngā pūnaha sima me ngā ranunga, ā, he whānui te urutau.
Te tiaki taiao me te kore parahanga: He hua matomato, he hua taiao hoki te whakaiti wai Polycarboxylate e tutuki ai ngā hiahia o te whanaketanga tauwhiro hou i roto i te hanganga.
4. Te mahi i roto i ngā tono mahi
4.1. Moata whakaōrite-ake
Mā te PCE ka pai te rere o te moata me te kaha ki te whakakī i a ia anō, he mea e tika ana mō te whakataurite i te whenua, te whakapiri me te whakatika.
4.2. Piripiri tāera, moata paraikete paparanga-angiangi
Whakapai ake i te āhua o te hanganga, whakarei ake i te piri ki te paparanga turanga, me te whakaiti i te ngatata.
4.3. Whakatikahia te moata me te rauemi whakakī
Whakaitihia te ōwehenga wai-sima, whakapai ake i te kiato me te mahi kaha wawe, e tika ana mō ngā kaupapa he kaha teitei me ngā whakaritenga rere teitei.
5. Ngā whakatūpato mō te whakamahinga
5.1. Te whakahaere i te horopeta
Ka nui rawa pea te rere o te moata, te turuturu wai, te roa rānei o te wā whakatakoto mēnā ka nui rawa te horopeta, ā, me whakarerekē tēnei i runga i te whakamātautau.
5.2. Te whakaranu ki ētahi atu ranunga
Me whakamātau i te PCE mō te hototahi ki ngā whakaroa, ngā kaihoko hopu hau, me ētahi atu, kia kore ai e taupatupatu te mahi.
5.3. Te awe o ngā rauemi mata
He nui te awe o te momo sima, te pai o te onepu, te pāmahana me ētahi atu mea ki te pānga o te PCE, ā, me arotau te ōwehenga ranunga kia rite ki ngā āhuatanga tūturu o te papaanga.
5.4. Te rokiroki me te kawe
Me ātete te PCE wai ki te huka, ki te rā, ā, me hiri hoki mō te rokiroki, ā, ko te roanga o te oranga mō te ono marama; me ātete hoki ngā hua paura ki te makuku.
He mea nui te mahi a te whakaiti wai polycarboxylate i roto i te moata simame tōna tino whai huatanga ki te whakaiti i te wai, te tino marara me te pupuri i te kirihou. I te whanaketanga tonu o ngā rauemi hanga matomato me te moata mahi-teitei, kei te arotau tonuhia te hoahoa whakatakotoranga me te hangarau tono o te PCE. Mā te whakamahinga whaitake o te PCE, ehara i te mea ka taea anake te whakapai ake i te mahi a te moata, engari ka āwhina hoki ki te whakatutuki i ngā whāinga rua o te tiaki pūngao me te whakaiti i ngā tukunga me te whakapai ake i te kounga hanga.
