Usuku lwePosi:Okuthengwa edolo,Mhlawumbe,2022

Lapho usimende uxutshwe namanzi, ngenxa yokuheha okuhambisanayo phakathi kwama-molecule kasimende, ukushayisana kokuhamba kwe-host of usimende kwikhambi, amacala aphambene amaminerali e-hydration ngesikhathi se-hydration, kanye nenhlangano ethile yamanzi ahlanganisiwe Ifilimu ngemuva kwamaminerali kasimende anama-hydrate. kuhlangene, ukuze i-slurry kasimende yakha isakhiwo se-floccution. Inani elikhulu lamanzi ashukumisayo lisongwe esakhiweni se-floccution, ukuze ingaphezulu lezinhlayiya zensimbi alinakuthintwa ngokuphelele ngamanzi, okuholela ekwandeni kokusetshenziswa kwamanzi nokwehluleka ukufeza ukusebenza kokwakha okudingekayo.

Ngemuva kokungeza i-superplastizer, iqembu le-hydrophobic le-molecule ekhokhiswayo ye-superplastic likhokhiswa kahle ngaphezulu kwezinhlayiyana kasimende, futhi iqembu le-hydrophilic likhomba kwikhambi lamanzi, okwenza ifilimu le-adssortion ebusweni bezinhlayiyana kasimende, ukuze kube yindawo kwenhlayiyana kasimende inemali efanayo. Ngaphansi kwesenzo sokuxoshwa kukagesi, izinhlayiya zosekhukhweni zihlukaniswe komunye nomunye, kanye nokwakheka kwe-floccution ye-slurry kasimende kuhlakazeka. Ngakolunye uhlangothi, amanzi amahhala esakhiweni se-floccution of the cement slurry akhishwa, okukhulisa indawo yokuxhumana phakathi kwezinhlayiya zamakhonkolo namanzi, ngaleyo ndlela akhuphule ukufutheka kwengxube; Ngaphezu kwalokho, ukuslayida phakathi kwezinhlayiya zomuntu nakho kukhuphuka ngenxa yokuqina kwefilimu yamanzi elungisiwe kwakhiwa ebusweni bezinhlayiya zokwenza usimende. Lesi yisisekelo sokuthi amanzi anciphisa amanzi anciphisa ukusetshenziswa kwamanzi ngenxa ye-adsorption, ukuhlakazwa, ukumanzi nokuthambisa.

Isimiso: Ngamafuphi, umenzeli wokunciphisa amanzi uvame ukuba yinto eqinile yokuthi ama-adederbs ebusweni bamakhaza kasimende, okwenza izinhlayiya zibonisa izakhiwo zikagesi. Izinhlayiya zixosha omunye ngomunye ngenxa yokukhokhiswa kukagesi okufanayo, ukuze izinhlayiya zensimbi zihlakazekile, futhi amanzi amaningi phakathi kwezinhlayiya akhishwa ukunciphisa amanzi. Ngakolunye uhlangothi, ngemuva kokungeza i-ejenti yokunciphisa amanzi, kwakhiwa ifilimu le-adsorption ebusweni bezinhlayiya zensimbi, okuthinta ijubane le-hydration yensimbi, kwenza ukukhula kwe-crystal kwe-slurry kusebenze kakhulu, isakhiwo senethiwekhi siphezulu MSENE, futhi uthuthukise amandla nobuningi besakhiwo se-slurry kasimende.

Lapho ukuncibilika kukakhonkolo kungafani, ukuhlangana okunganciphisa ukusetshenziswa kwamanzi kubizwa ngokuthi amanzi e-fuccrete. I-ejenti yokunciphisa amanzi ihlukaniswe ngamanzi ajwayelekile anciphisa i-ejenti kanye ne-ejenti yokunciphisa amanzi aphezulu. Labo abanezinga lokunciphisa amanzi abangaphansi noma elilingana no-8% babizwa ngokuthi ama-8% ajwayelekile amancane, nalabo abanesilinganiso sokuncipha kwamanzi abangaphezu kuka-8% babizwa ngokuthi ama-subvucers aphezulu wamanzi. Ngokwemiphumela ehlukene ama-superplastifizers angaletha ukhonkolo, ahlukaniswe ngama-superplastizer asebenza ngamandla okufika kusenesikhathi kanye nama-superplastizers afaka umoya.

Ngokwethula umsebenzi wokwengeza i-ejenti yokunciphisa amanzi ukusayina umenzeli welapha, sinokuqonda okucacile ngenkinga yokwengeza umenzeli we-ejenti ekwelulentekile. Ngamagama alula, indima ye-ejenti yokunciphisa amanzi i-ejenti esebenzayo engaphezulu, engenza ukuthi izinhlayiya zensimbi ziveze i-electrode efanayo, futhi zikhulule amanzi phakathi kwezinhlayiya ngezinto ezibonakalayo ezisolwa okufanayo, ngaleyo ndlela kunciphisa amanzi.
