te whakaiti wai polycarboxylate i roto i te raima kaha teitei

I te whanaketanga o te umanga hanga ki te mahi teitei, te kaha teitei me te tiaki taiao matomato, kei te whakapai tonu ngā whakaritenga mahi o ngā rauemi raima. He whānuitia te whakamahinga o te raima kaha teitei i roto i ngā whare teitei, ngā piriti, ngā hanganga nui me ētahi atu kaupapa hangarau nā te mea he pai rawa ngā āhuatanga miihini me te roa. Hei ranunga raima mahi teitei o te tuatoru o ngā whakatipuranga,whakaiti wai polycarboxylatekua noho hei rauemi matua e tika ana mō te whakarite i te raima kaha-teitei nā te mea he pai ake tōna ngāwari ki te marara me te ātete ki te hinga.

1. Ngā āhuatanga mahi o te whakaiti wai polycarboxylate

Ko te whakaiti wai Polycarboxylate he momo hou o te whakaiti wai mahi-teitei i hangaia mā te whakauru i ngā rōpū mahi maha me te polyether me te waikawa acrylic hei mekameka matua. Ko tōna hanganga ngota he mea tito mai i ngā rōpū adsorption mekameka matua me ngā rōpū aukati steric mekameka taha, he nui te hoahoa me te mahi. Ki te whakatauritea ki ngā whakaiti wai naphthalene tuku iho, ki ngā whakaiti wai aliphatic rānei, he pai ēnei painga nui o ngā whakaiti wai polycarboxylate:

Te tere whakaheke wai teitei: Ka taea e te whakaiti wai polycarboxylate te whakatutuki i te tere whakaheke wai neke atu i te 20% i te horopeta iti, ka whakaitihia te ōwehenga wai-sima o te raima, ā, ka whakapai ake i tōna kaha.

He tino pai te marara me te pupuri i te totohu: Ka taea e tōna hanganga ngota te hanga i tētahi paparanga mimiti pumau i runga i te mata o ngā matūriki sima, ka whakaiti i te kukume i waenga i ngā matūriki, ka pupuri i te rere pai.

Te iti o te ngaromanga o te hinga: Mā te whakarerekē i te roa me te mātotoru o te mekameka taha i roto i te hanganga ngota, ka taea te whakapai ake i te mahi pupuri hinga o te raima kia tutuki ai ngā hiahia o te hanganga mō te wā roa.

He hototahitanga pai: He pai te urutau o te whakaiti wai polycarboxylate ki ngā momo ranunga sima me ngā kohuke rerekē (pēnei i te pungarehu rere, te paura para, te paoa silica), he mea e pai ana mō te hoahoa arotau o te pūnaha raima mahi-teitei.

He matomato, he hoa taiao: He pai te tukanga hanga ki te taiao, he iti noa ngā hua taha, ā, e tutuki ana i ngā whakaritenga o te whanaketanga tauwhiro.

2. Ngā whakaritenga taketake mō te raima kaha-teitei

Ko te raima kaha-teitei e pā ana ki te raima he kaha pēhi pūtoru C60, neke atu rānei. Hei whakatutuki i te kaha teitei, me whakaiti te ōwehenga wai-sima, me te whakarite hoki i te pai o te mahi hanga (pēnei i te kaha papu, te rere) me te pakari. Hei whakatutuki i tēnei, me whakamahi i ngā taputapu whakaiti wai tino whai hua hei whakapai ake i te mahi a te raima, ā, ko ngā taputapu whakaiti wai polycarboxylate te whiringa pai hei whakatutuki i tēnei whāinga.

3. Ngā painga o te whakaiti wai polycarboxylate i roto i te raima kaha-teitei

Whakapai ake i te kaha o te tīmatanga me te mutunga: ka whakaitihia e te whakaiti wai polycarboxylate te ōwehenga wai-sima me te pupuri tonu i te rere pai, kia tino makuku ai te sima, kia whakapai ake i te kaha o te tīmatanga me te mutunga o te raima, ā, kia tutuki ai ngā whakaritenga hoahoa o ngā hanganga kaha-teitei.

Whakapai ake i te mātotoru o te hanganga raima: ka whakaiti i te ōwehenga wai-sima me te kore e pā ki te mahi, ka āwhina ki te whakaiti i ngā uaua toto, ka whakapai ake i te mātotoru me te ātete o te raima, ā, ka whakapakari i tōna pakari.

Whakapai ake i te mahi hanga: I roto i te raima kaha-teitei, he maha ngā wā ka matotoru te ranunga nā te nui o te sima. Mā te tino pai o te whakamararatanga o te whakaiti wai polycarboxylate ka taea te whakapai ake i te rere o te raima, te whakaiti i te piripono, me te whakapai ake i te pai o te papu.

He mea nui te pānga o te whakakotahitanga me ngā ranunga kohuke: he pai te pānga tahi o te whakaiti wai polycarboxylate me ngā ranunga pēnei i te pungarehu rere, te paura para, me te paoa silica, e āwhina ana ki te arotau i ngā āhuatanga whānui o te raima, pēnei i te kaha, te roa, te mimiti, me ētahi atu.

Whakaitihia te utu whānui: Ahakoa he nui te utu mō te whakaiti wai polycarboxylate, ka taea e tōna whai huatanga teitei te whakaiti i te whakapaunga sima, te whakaiti i te whakapaunga pūngao, te whakapai ake i te kounga o te kaupapa, me te whakatutuki i ngā painga ōhanga whānui ake.

4. Tātaritanga take tono

I roto i tētahi kaupapa whare tino teitei, me C80 te kaha o te raima, ā, he pai te mahi me te roa o te mau. I whakamahia e te tīma kaupapa te whakaiti wai mahi-teitei o te polycarboxylate, me ngā ranunga matūriki kohu silica me te paura para, ā, i angitu te hanga i te raima kaha-teitei i tutuki ai ngā whakaritenga hoahoa mā te arotau i te ōwehenga wai-sima me te whakatauranga rahi matūriki. E whakaatu ana ngā hua whakamātautau ko te kaha pēhi o te raima mō ngā rā 28 neke atu i te 85 MPa, ā, ko te wā pupuri totohu neke atu i te 2 hāora, e tutuki ai ngā hiahia o te hanganga me te papu i te papaanga, ā, e whakaatu ana hoki i ngā āhuatanga pai o te ārai-huka, te ārai-mimi me te ārai-waro.

5. Ngā raruraru o nāianei me ngā aronga whanaketanga

Ahakoa e whakamahia whānuitia ana te whakaiti wai polycarboxylate i roto i te raima kaha-teitei, kei reira tonu ngā wero e whai ake nei i roto i ngā kaupapa tūturu:

Ngā take hototahi ki ētahi sima: Tērā pea ka rahua te whakaiti wai, ka heke rānei te mahi pupuri wai i ētahi momo sima, ā, me rangahau i te āheinga urutau.

Te aro nui ki te taiao hangahanga: He aro nui te whakaiti wai polycarboxylate ki ngā āhuatanga taiao pēnei i te pāmahana me te haumākū, ā, me whakahaere tika ngā tikanga whakamahi.

He uaua te tukanga whakahiato, ā, he nui te utu: I tēnei wā, ko ngā kaupapa hangarau mahi-teitei tonu ngā kaupapa matua o te tono, ā, he mea nui kia whakaitihia ngā utu mā te arotau i ngā tukanga hei whakatairanga i te rongonui.

Ka arotahi te whanaketanga o te whakaiti wai polycarboxylate ki ngā āhuatanga e whai ake nei: Tuatahi, te arotautanga atu i te hanganga ngota hei whakatutuki i te whakapainga tahi o te whakaiti wai me te pupuri hinga; tuarua, te whanaketanga o te whakaiti wai atamai, pēnei i te momo tairongo pāmahana, te momo tuku puhoi, me ētahi atu; tuatoru, te rangahau i te ara hanga matomato me te hoa taiao hei whakatairanga i te whanaketanga pumau; tuawhā, te hoahoa atamai o te ōwehenga ranunga raima me te hono atu ki te AI, ki te raraunga nui rānei.

Whakaiti wai Polycarboxylatekua noho hei ranunga matua mō te whakarite i te raima kaha-teitei me tōna mahi tino pai. Mā te hoahoa me te tono pūtaiao me te whaitake, kāore e taea anake te whakatutuki i ngā whakaritenga maha o te raima mahi-teitei mō te miihini me te mahi, engari ka taea hoki te whakapai ake i te kounga hangarau me te whai huatanga o te hanga. I roto i te horopaki o te whakapai tonu i te hangarau hanga a meake nei, ka whakamahia e te whakaiti wai polycarboxylate tōna pūmanawa nui i roto i te mara whānui.
