Kia pehea te nui o to mohio mo te kaihoko whakaheke wai?

Te Ra Whakairi:9, Hepetema, 2024

Ko te whakaheke wai he whakauru raima ka taea te whakaiti i te nui o te whakaranu wai i te wa e mau tonu ana te heke o te raima. Ko te nuinga o ratou he surfactant anionic. I muri i te taapiri atu ki te ranunga raima, he paanga marara ki nga matūriki ciment, ka taea te whakapai ake i tana mahi, te whakaiti i te kohi wai o te waeine, me te whakapai ake i te rere o te ranunga raima; whakaitihia ranei te kohi ciment wae me te whakaora sima.

E ai ki te ahua:
Ka wehewehea ki te wai-wai me te paura. Ko te tikanga he 10%, 20%, 40% (e mohiotia ana ko te waipiro whaea), 50%, ko te mea totoka o te paura he 98%.

E ai ki te kaha ki te whakaiti i te wai me te whakarei ake i te kaha:
Kua wehea ki te whakaheke wai noa (e mohiotia ana ano ko te plasticizer, me te reiti whakaheke wai kia kaua e iti iho i te 8%, e tohuhia ana e te lignin sulfonates), te whakaheke wai kaha-nui (e mohiotia ana ano ko te superplasticizer, me te reiti whakaheke wai kaore e iti ake. nui atu i te 14%, tae atu ki te raupapa naphthalene, te raupapa melamine, te raupapa aminosulfonate, te raupapa aliphatic, me etahi atu) me te whakaheke wai mahi nui (kaore i te iti te tere o te whakaheke wai. nui atu i te 25%, e tohuhia ana e te whakaheke wai raupapa waikawa polycarboxylic), ka wehea ki te momo kaha moata, te momo paerewa me te momo whakatakotoranga puhoi.

E ai ki nga rauemi hanganga:
Lignin sulfonates, polycyclic aromatic salts, wai-soluble resin sulfonates, naphthalene-based high-efficiency water reducers, aliphatic high-efficient water reducers, amino high-efficiency whakaiti wai, polycarboxylate high-performance water reducers, etc.

E ai ki te hanganga matū:
Ko nga whakaheke wai whai mana o te Lignin sulfonate, te whakaheke i te wai o te naphthalene, te whakaheke i te wai melamine, te whakaheke wai-a-aminosulfonate, te whakaheke wai-a-waikawa-a-waikawa, te whakaheke wai-a-polycarboxylate. .

Te mahi a te whakaheke wai:
1.Kaore e whakarereketia te tauwehenga o nga momo rauemi mata (haunga te ciment) me te kaha o te raima, ka taea te whakaiti i te nui o te ciment.
2.Kaore e whakarereketia te tauwehenga o nga momo rauemi mata (haunga te wai) me te paheketanga o te raima, ko te whakaiti i te nui o te wai ka taea te whakapai ake i te kaha o te raima.
3.Ki te kore e whakarereketia te tauwehenga o nga momo rauemi mata, ka taea te whakapai ake i te rheology me te kirihou o te raima, kia taea ai te hanga raima ma te kaha, te pupuhi, te kore wiri, me etahi atu, hei whakanui ake i te tere o te hanga me te whakaiti i te kaha o te hanga. .
4.Ko te taapiri i te whakaheke wai kaha-nui ki te raima ka taea te whakanui ake i te oranga o te raima ma te neke atu i te rua, ara, ka roa ake te roa o te mahi o te whare i te rua.
5.Whakaitihia te tere o te whakaheke o te raima raima me te aukati i nga pakaru o nga waahanga raima; te whakapai ake i te haupapa, he pai ki te hanga hotoke.
