Tsvagiridzo pamusimboti wekushanda wedhaka poda uye polycarboxylic acid inoderedza mvura mumiririri:
Zvinowanzotendwa kuti chikonzero chikuru nei hupfu hwematope hunokanganisa kongiri yakasanganiswa ne lignosulfonate uye naphthalene-based water reduction agents ndiyo makwikwi ekushambadza pakati pehupfu hwevhu nesimende.Hapasati pasisina tsananguro yakabatana pamusimboti wekushanda wehupfu yedhaka uye polycarboxylic acid inoderedza mvura.
Dzimwe nyanzvi dzinofunga kuti nheyo yekushanda yehupfu hwevhu uye mvura inoderedza mvura yakafanana neyesimende.Mushonga wekudzikisa mvura unoshambadzirwa pamusoro pesamende kana dhaka poda nemapoka eanionic.Musiyano ndewekuti chiyero uye chiyero chekushambadza kwemvura-kudzikisa agent nedhaka poda yakakura kwazvo kupfuura yesamende.Panguva imwecheteyo, iyo yakakwirira chaiyo nzvimbo uye akaturikidzana chimiro chevhu zvicherwa zvinotorawo mvura yakawanda uye kuderedza mvura yemahara mu slurry, iyo inokanganisa zvakananga kuita kwekuvaka kwekongiri.
Mhedzisiro yemaminerari akasiyana pakuita kwemvura inoderedza vamiririri:
Tsvagiridzo inoratidza kuti dhaka revhu chete rine kuwedzera kwakakosha uye kunyudza mvura zvivakwa zvichave nemhedzisiro yakakosha pakushanda kwekushanda uye gare gare michina yekongiri.
Madhaka evhu akajairika muzvikamu zvinonyanya kusanganisira kaolin, illite uye montmorillonite.Rudzi rwakafanana rwemugadziri wekudzikisa mvura ane hunhu hwakasiyana kune hupfu hwedhaka nemhando dzakasiyana dzemaminerari, uye musiyano uyu wakakosha zvakanyanya pakusarudzwa kwevashandi vanodzikisa mvura uye kugadzirwa kwedhaka rinodzivirira mvura rinodzikisa uye rinorwisa madhaka.
Mhedzisiro yedhaka poda yemukati pane kongiri zvivakwa:
Kushanda kwekongiri hakungokanganisa kuumbwa kwekongiri, asi kunokanganisa zvakare ma mechanical properties uye kusimba kwekongiri.Huwandu hwehupfu hwemadhaka husina kugadzikana, hunoderera kana hwaoma uye huchiwedzera kana hwanyorova.Sezvo madhaka ari kuwedzera, angave ari polycarboxylate-anoderedza mvura agent kana naphthalene-based-water-reducing agent, inoderedza mvura inoderedza chiyero, simba, uye kudonha kwekrete.Kudonha, nezvimwewo, kuunza kukanganisa kukuru kune kongiri.
