Nga Whakapiri Raima Maamaa | Nga Kaipupuhi Hukarere Mahinga Nui mo te Raima Pukoro
He aha te take i whakahekehia ai e te polycarboxylate superplasticizer te whakaheke toto o te raima?
Ko te waikawa polycarboxylic superplasticizer he superplasticizer pūhui wai-wairewa te nuinga tito o carboxylate hono waerau, ka taea te whakapai ake i nga momo momo raima, whakapai ake i te kaha, anti-permeability, anti-carbonation, anti-shrinkage me te mauroa o te raima. Heoi ano, na te awe o nga momo ahuatanga, te raima i konatunatua ki te waikawa polycarboxylic te whakaheke wai ka maha tonu ka puta tomuri, te toto me etahi atu tohu, ka tino pa ki te hanga.
Ko nga tino take e whai ake nei:
(1) Te whakamahi nui o te whakaiti wai waikawa polycarboxylic
Ka taea e te kaihoko whakaheke wai waikawa polycarboxylic te whakapai ake i te whakaheke raima, engari he nui rawa te ranu, he nui rawa te reiti whakaheke wai (tata ki te rohe o te ranu, he nui ake te reiti whakaheke wai 40%). Ko te kaha marara he tino kaha ka tino whakaitihia te whakakotahitanga o te raima me te nui ake o te wai kore utu ka tukuna, na reira ka piki ake te kaha o te toto raima. Ina koa ka whakamahia e te tangata te tuku puhoi me te whakaheke wai waikawa polycarboxylic momo whakaheke, he mea ngawari ki te whakauru i te nui o te toto ka pakaru te toto o te raima me te wehe i te wa e tino kino ana. No reira, i mua i te whakamahi, he mea tika ki te whakahaere i te whakamātautau wā matatau ki te mātakitaki i te huringa o te āhua raima.
(2) Ko te whakaheke wai waikawa polycarboxylic he tairongo ki te pāmahana o te taiao, he puhoi te tuku taonga
Ka whakatauritea ki etahi atu taputapu whakaheke wai, Ko nga ahuatanga o te waikawa polycarboxylic te kai whakaheke wai ka tino pa ki te pāmahana. I te raumati, ina teitei ake te mahana, ko te whakaheke wai waikawa polycarboxylic me te pai o te mahi whakaheke ka puta he tohu whakaheke “ringihia nui” āhuatanga ka heke ohorere te pāmahana. No reira, ka heke ohorere te pāmahana, me whakamatau te superplasticizer waikawa polycarboxylic taketake i mua i te whakamahi. I te wa whakaputa, te wa whakakorikori kia tika te whakaroa kia marara katoa me te tuku i te superplasticizer waikawa polycarboxylic, kia kore ai e pa mai te tukunga puhoi i te wa o muri mai, ka hua te kore o te pupuri wai o te raima me te rerenga wai.
(3) Taapirihia he wai whakaheke wai waikawa polycarboxylic hei whakatika i te heke
I mua i te ringihanga raima, ka kitea ko te mahi o te ranunga raima kaore e tutuki i nga whakaritenga hanga, Ko te kaha o te mahi o te raima ka whakatikahia ma te taapiri i te superplasticizer waikawa polycarboxylic ki te whakaranu raima.. Heoi ano, ina whakatikahia te taapiri tuarua, i etahi wa kaore e taea te hopu tika i te nui o te whakamahinga. A, no te nui o te superplasticizer nui te whakaritenga ariā, ka whai waahi tonu te superplasticizer nui i muri i te ringihanga raima, hanga te waenganui o te tātari tohatoha wai raima. No reira, i te wa e whakamahi ana i te superplasticizer hei whakatika i te mahi o te raima, me tapiri te raima i nga wa rereke kia rite ki te nui o te raima, me whakakaha te ranu kia pai ai te whakaranu me te nui o te taapiri.
(4) I te whakakotahitanga o te superplasticizer waikawa polycarboxylic, kare i tika te whakamahi i te retarder
I roto i te tikanga ki te whiwhi slump pai mahi tiaki o te raima, he maha nga wa ka taapirihia etahi waahanga whakaroa i te wa e konatunatua ana te kai whakaheke wai. Ina he nui rawa te nui o te waahanga whakaroa, i te wa pai ranei te pāmahana engari ka paheke te pāmahana o te waikawa polycarboxylic superplasticizer, he nui rawa atu nga waahanga whakaroa ka whakapoipoi i te whakamakuku o te sima ka whakaheke toto te raima. Na reira me whakarongo koe ki te awe o nga waahanga o te wai huna raima whakamuri. Ina koa i te waahi nui o te pāmahana i waenga i te ao me te po i te wa o te puna me te ngahuru, kia nui ake to aro ki te nui o te retarder, kia i roto i te tukanga tautuhinga raima, ka taea e koe te aukati i te rere o te wai, totohu whakahiato, kia whakaheke toto.
(5) hototahitanga i waenga i te ciment me te whakaiti wai waikawa polycarboxylic
He uaua te hanganga o te raima me te ngawari ki te whakaputa i nga huringa matū kore i tuitui i waenga i nga waahanga. Mena he ngoikore te hototahi o te ciment me te superplasticizer waikawa polycarboxylic, ka whakanuia te ihirangi kukū o te superplasticizer, a ka whakaroahia e te superplasticizer te taima te wa whakatuu raima, me wehe te wai kore utu o te raima. I tua atu, ina he iti te kawakore whakarewa i roto i te sima, ka puhoi te reiti whakamakuku o te sima, me te ahua o te whakaheke toto ka puta.
I tua atu, i roto i te tukanga whakaputa o te raima, he maha nga wa ka pa te tangata ki nga rereketanga o te kounga o te kirikiri, penei he nui ake, iti iho ranei te ahua o te paru, he nui ake, he iti ake ranei te nui o te wai, whakarōpūtanga whakaemi, etc. Ko enei katoa ka puta he toto raima, he wehewehe ranei.
Ko Cie-China.org te kaiwhakarato taapiri raima pahuka e whakarato ana i te kaihoko hukapapa raima, superplasticizer,whakakaha kaha raima pahuka mo te raima mama, Nga poraka CLC. Mena kei te rapu koe superplasticizer, tēnā koa koa whakapā mai.
