Polycarboxylate(PCE, Polycarboxylate Ether) he matū nui e whakamahia whānuitia ana i roto i ngā matū hanga, inā koa i roto i ngā hanganga raima mahi-teitei. Nā tōna kaha ki te horapa me te hototahi ki ngā pūnaha sima rerekē, kua noho ngā hua e ahu mai ana i te polycarboxylate hei wāhanga nui o te hangarau whakaranu raima hou.

Te Whakapai Ake i te Whai Huatanga o te Mararatanga o te Sima

I roto i te hanga raima, he wero nui mā ngā kaihanga te pupuri i te pai o te mahi me te whakaiti i te whakamahinga wai. Ka āwhina ngā tāpiringa kei roto i te polycarboxylate ki te whakapai ake i te marara o ngā matūriki sima, ka taea ai e ngā ranunga raima te whakatutuki i te rere me te pumau pai ake me te whakamahinga wai kua tino pai.

Ki te whakaritea ki ngā matū whakaiti wai tuku iho, he nui ake te ngāwari o ngā hua polycarboxylate ki te hoahoa whakatakotoranga. He mea whakamahi noa ēnei i roto i ngā tono e hiahia ana kia tino whai hua, tae atu ki te raima kua oti te whakaranu, te raima kua oti te hanga, me ngā kaupapa raima kaha teitei.

Te Hiranga o ngā Rauemi Hanga Mahi-Tiketike

I te mea e hiahiatia ana ngā rauemi e pakari ake ana, e pai ake ana hoki te mahi tukatuka mō ngā kaupapa hanga, e whakamahia whānuitia ana ngā superplasticizer e hangai ana ki te polycarboxylate i roto i ngā pūnaha raima maha.

Ko ō rātou painga ko:

• Te rere pai ake o te raima;
• Te pupuri i te ngāwari o te mahi;
• Te whakaiti i te hiahia mō te wai;
• Hototahi ki ngā rauemi sima rerekē.

Nā ēnei āhuatanga ka waiho te polycarboxylate hei wāhanga nui o te whanaketanga o ngā rauemi hanga hou.

He mea nui te ōritetanga o te kounga mō ngā kaihoko ahumahi

Mō ngā kaihanga ranunga raima, ka pā tika te pumau o te kounga o ngā hua polycarboxylate ki te mahi o te hanganga whakamutunga. I te wā e hoko ana, ka aro nui ngā kaihoko ki:

• Te mahi matū pumau i waenga i ngā puranga;
• Hototahi ki ngā momo sima rerekē;
• Te pumau o te ihirangi me ngā tawhā hangarau;
• Te kaha pono ki te tuku.

Mā te pumau o ngā rauemi mata ka āwhina i ngā kaihanga ki te pupuri i te kounga hua ōrite me te whakapai ake i te whai huatanga o te whakaputa.

Ngā Whakaaro mō te Rokiroki me te Whakahaere

Me rongoa ngā hua polycarboxylate i raro i ngā āhuatanga tika hei pupuri i tō rātou mahi. Ko te tikanga, ka aro nui ngā kaiwhakamahi ahumahi ki te pāmahana rokiroki, te kounga o te takai, me te tiaki i a rātou mai i te poke i te wā e kawe ana.

Mā te whakahaere tika o te rokiroki ka āwhina i te pumau o te hua, ā, ka whakarite hoki kia maeneene te whakamahinga i roto i ngā whakatakotoranga o muri mai.

Te Tautoko i te Whakawhanaketanga o ngā Matū Hanga Matatau

He mea nui te polycarboxylate i roto i ngā pūnaha whakaranu raima, ā, kei te tautoko tonu ia i te whanaketanga o ngā rauemi hanga whai hua ake, pumau ake hoki. Nā tōna kaha ki te whakapai ake i te mahi rauemi me te arotau i te hoahoa whakatakotoranga, he mea nui tēnei hei wāhanga matū i roto i ngā ahumahi hanga hou.

Mō ngā kaihoko ahumahi, ko te kounga hua pono, te tautoko hangarau ngaio, me te kaha tuku pumau tonu ngā mea matua i te wā e whiriwhiri anapolycarboxylatengā kaiwhakarato.
