Nga ngota ngota o tehe kaihoko whakaheke wai polycarboxylatehe mea hanga ma te "hoahoa rapoi" me te hanganga "heru" he "dendritic" ranei, a he maha nga manga o te roa me te rigidity e piri ana ki te mekameka matua o te ngota ( Side chain).He sulfonates etahi atu roopu ranei kei runga i te mekameka matua ka taea te utu i nga matūriki ciment, ka taea te mahi hei whakaheke wai tuku iho.Ko te mea nui ake, ka uru te mekameka matua ki te mata o nga matūriki ciment, ka pahekoheko nga mekameka manga ki te mata o etahi atu matūriki.Ko nga mekameka manga ka hanga he wahanga-toru, e aukati ana i nga matūriki kia kore e tata ki a ratau, kia tutuki ai te paanga o te marara (ara te whakaheke wai).Ko tenei arai aukati kaore e ngoikorehia e te roanga o te waa, na reira, ko te mararatanga o teRaima me te moata Superplasticizer Polycarboxylate Superplasticizer(PCE paura)he roa ake.

Hangahanga matū Whakaheke wai Polycarboxylate Superplasticier(PCE Liquid) Ko te whakaheke wai mahi teitei ko te tuatoru o nga whakatipuranga o te whakaheke wai mahi teitei i whakawhanakehia i muri i te whakaheke wai noa e tohuhia ana e te konupūmā rakau me te whakaheke wai tino pai e whakaatuhia ana e te raupapa naphthalene.I tenei wa ko te tino matatau o te ao., He superplasticizer me nga ihirangi pūtaiao me te hangarau teitei, te tirohanga tono pai me te mahinga matawhānui pai.

Polycarboxylate Superplasticizer PCE Wai Pupuri Pupurihe nui te wahanga o nga kai kaha me te awhe taumahatanga ngota ngota.No reira, ka whakatauritea ki etahi atu taputapu whakaheke wai,te waikawa polycarboxylic hei whakaheke waiehara i te mea he nui ake te reiti whakaheke wai, engari ka mau tonu te heke, ka iti ake te inenga..Ko te raima kua rite ki te waikawa polycarboxylic-a-waikawa-a-te-a-te-nui-a-te-wai-whakaiti karekau e kitea te wehewehenga me te whakaheke toto ahakoa te ahua o te paheketanga nui, a ka rite te ahua me te tae o te raima.He tino painga mo te whakarite i te raima teitei, te raima-a-whaiaro, te raima-whaiaro, me te raima ataahua.I te wa e whakamahia ana i roto i te whakaritenga o te raima teitei, he pai te mahi o te raima, he pai te whakakotahi, he ngawari te whakauru o te raima.He pai te hototahi ki nga momo ciment me nga whakauru, me te whakaoti i te raruraru hototahi o etahi atu momo taputapu whakaheke wai me nga rauemi cimentitious.
