Yintoni iarhente yokupheliswa kwamanzi?
Iarhente yokunciphisa amanzi, ikwabizwa ngokuba yi-disperbant okanye iplastiki, yeyona nto isetyenziswa kakhulu kwaye inyanzelekile kwikhonkrithi yekhonkrithi. Ngenxa yoKhuseleko kunye nokusasazeka, kunye neziphumo ezimanzi, kunokunciphisa ukusetyenziswa kwamanzi kwikhonkrithi entsha ngokusetyenziswa, oko kukuphucula amandla, ukuqina kunye nezinye iipropathi zekhonkrithi.
I-arhente encitshiswa kwamanzi inokwahlulwa ibe yimisebenzi emibini ngokokucofa kwamanzi Iarhente encitshiswa kwamanzi idityaniswa kunye nokunyeliswa kobunye uhlobo lodidi lwakwangoko, uhlobo oluqhelekileyo, uhlobo lokubuyisa kunye nohlobo lomoya ongenela i-arhente yokunciphisa amanzi ngokweemfuno zobunjineli kwisicelo.
Iiarhente zokunciphisa amanzi zinokwahlulwa zibe yi-lignosulfosulfosulfosulfosulfosulfosul kunye ne-Polycyclic i-Alid Sultonic Acid, i-Aliphic Sullonic Acid, i-Polybonic Acid, Polyoxyylene, Iikhemikhali eziphambili izinto.
Ithini indlela yentshukumo yomgangatho wamanzi?
Onke iiarhente zokunciphisa amanzi ziiarhente ezisebenzayo zomphezulu. Iziphumo zokuncitshiswa kwamanzi zearhente yokunciphisa amanzi ikakhulu zifunyenwe ngumsebenzi womphezulu wearhente yokunciphisa amanzi. Eyona ndlela iphambili yokunciphisa amanzi imigangatho emiselweyo:
1) Umgangatho wamanzi uza kusebenza kwi-intermy eqinileyo-yolwelo, uphucule ubunzi bomphezulu, ukuphucula ubunzi bamasuntswana, ukunciphisa ukungazinzi kwesamente, kwaye ke ufumana uzinzo lwesihlobo.
2) Umgangatho wamanzi uza kuvelisa i-adsorction yendlela yokuthambisa, ukuze umphezulu weethafa zesamente uya kuba nentlawulo efanayo, ukuvelisa i-elektrostatic, ke ngoko ukutshabalalisa isakhiwo esirekhodiweyo samasuntswana kunye nokusasaza amasuntswana. For polycarboxylate and sulfamate superplasticizers, the adsorption of the superplasticizer is in the form of ring, wire and gear, thus increasing the distance between cement particles to generate electrostatic repulsion, showing better dispersion and slump retention.
3) Ifilimu yamanzi enyibilikiswa ye-hydrogen ye-hydrogen ye-hydrogen phakathi komgangatho wamanzi kunye neemolekyuli zamanzi ukuvelisa ukhuseleko lwendawo, thintela ukunxibelelana ngqo kwamasuntswana kunye nokuthintela ukwakhiwa okuphezulu.
4) Njengokuba umaleko we-adsorption senziwa kumphezulu wamasuntswana wesamente, oko kungathintela i-hidration yokuqala yesamente, ngaloo ndlela ekwazi ukwandisa ivolumu yamanzi asimahla kunye nokuphucula ulwalamano lwesamente.
I-5) Iiarhente zokunciphisa amanzi ziya kwazisa ngesixa esithile seebhubhu ezincinci ukunciphisa ukuxabana phakathi kwamasuntswana empahla, ngaloo ndlela ukuphuculwa kokusasazeka kunye nokuzinza kwesamente.
