Kana simende yakavhenganiswa nemvura, nekuda kwekukwevera kwekukwezva pakati pemamorita emanyorero, kupokana kwekunyora kwemukati kwemhinduro, iyo mhosva yezvikara zvemukati, uye imwe kusonganiro yemvura yakagadziriswa firimu mushure mekunge zvimisikidzwa zvicherwa. yakasanganiswa, kuitira kuti simbe slurry inoumba chimiro chekutanga. Mari yakakura yekumhanyisa mvura yakaputirwa muchimiro chekusimbisa, zvekuti pamusoro pechikamu chechisimba chisingakwanisi kubatanidzwa zvizere nemvura, zvichikonzera kuwedzera kwemvura uye kutadza kuwana maitiro ekuvaka anodiwa.

Mushure mekuwedzera iyo Superplasticastizer, boka re hydrophobic remubhadharo wepamhepo rakashamiswa, uye hydrophic group rondedzero, vachiumba firimu rekushungurudzika pamusoro peiyo simende. yeiyo simenment timende ine mutero mumwechete. Pasi pechiitiko chekudzora kwemagetsi, zvidimbu zve simende zvakaparadzaniswa kubva kune mumwe nemumwe, uye chimiro chekutanga chechisimba chinosimbisa chinoparadzirwa. Kune rimwe divi, mvura yemahara mumamiriro ekurongedza yeiyo simende inosunungurwa, inowedzera nzvimbo yekuonana pakati peiyo simenti uye nemvura, nekudaro ichingowedzera iyo fluidity yemusanganiswa; Uyezve, kutsvedza pakati peiyo simenmenti inowedzerawo nekuda kwekukora kweiyo yakagadziriswa yemvura yemifananidzo yakagadzirwa pamusoro pechikamu chechidimbu. Iyi ndiyo nheyo yekuti mvura inoderedza vamiririri kuderedza mvura yemvura nekuda kwe adsorption, kupararira, kunyorova uye lubrication.

Nheyo: Muchapfupi, mvura inoderedza mumiririri kazhinji inowanzoita siractors iyo adsorbs pamusoro peiyo simenti yezvikamu, zvichiita kuti zvidimbu zvinoratidza zvemagetsi. Izvo zvimedu zvinodzosera mumwe nemumwe nekuda kwekuti iwo mamwe emagetsi emagetsi, zvekuti nzvimbo dzechisimba dzakaparadzirwa, uye mvura yakawandisa pakati pezvikamu zvinoburitswa kuti ideredze mvura. Kune rimwe divi, mushure mekuwedzera mvura yekudzora mumiririri, firimu rekushambadzira pamusoro peiyo simenti yekunyepedzera, inokanganisa kukura kweiyo simenti slurry yakakwana, iyo network mamiriro ezvinhu dense, uye inovandudza simba uye kurongeka kweiyo simenti slurry.

Kana kutsvedza kwekongiri kuri zvakafanana, kufungidzira kunogona kuderedza mvura yemvura kunonzi kongiri yemvura kuderedza mvura. Mvura inoderedza mumiririri inokamurwa kuita kuti mvura yakajairwa yekudzora mumiririri uye yakakwirira-yekubudirira mvura kudzora mumiririri. Vaya vane mwero wekudzikisa mvura pane zvishoma kana kuenzana ne8% vanonzi vakajairwa mvura vanodzikisira, uye avo vane huwandu hwekudzora mvura kupfuura 8% vanonzi mvura yakakwirira-inobudirira mvura inokatyamadza. Zvinoenderana nemhedzisiro dzakasiyana iyo inokonzeresa kuti ive yepamusoro inogona kuunza kongiri, ivo vakakamurwa kuva pakutanga-simba vanowanda uye mhepo-yekupinza mashura anokwenenzverwa.

Nekusuma basa rekuwedzera mvura kuderedza mumiririri kuti asimbe mumiririri, isu tinonzwisisa zvakajeka padambudziko rekuwedzera mumiririri mukuvakwa kwesimbe mumiriri. Muzvirevo zviri nyore, basa remvura rinoderedza mumiririri anoshanda mumiririri, izvo zvinogona kuita kuti zvidimbu zvigadzikane neakasiyana electrode.
