Yini eyehlisa amanzi i-ejenti?
Amanzi anciphisa i-ejenti, eyaziwa nangokuthi i-dispersant noma i-Plistic, yisengezo esisetshenziswa kakhulu futhi esisezingeni elifanele kukhonkolo oxubile olungiselelwe. Ngenxa ye-adsorption yayo e-adsorption kanye nokuhlakazeka, imiphumela emanzi futhi eshibhile, kunganciphisa kakhulu ukusetshenziswa kwamanzi kokhonkolo omusha ngokusebenza okufanayo ngemuva kokusebenza, ngaleyo ndlela kuthuthukiswe amandla ngokhonkolo.
I-ejenti yokunciphisa amanzi ingahlukaniswa ngezinhlobo ezimbili ngokuya ngomphumela wayo wokunciphisa amanzi: amanzi ajwayelekile anciphisa umenzeli kanye ne-ejenti ephakeme yokunciphisa amanzi. I-ejenti yokunciphisa amanzi ingahlanganiswa namanye ama-admixtures ukwakha uhlobo lwamandla okuqala, uhlobo olujwayelekile, uhlobo lokubuyisa kabusha nomoya wokufaka umoya ukunciphisa umenzeli ngokuya ngezidingo zobunjiniyela
Ama-ejenti anciphise amanzi angahlukaniswa abe yi-lignosulfonate kanye nokutholwa kwawo, ama-polycyclic aphunga elikhanyayo acid acid, usawoti we-aliphatic, ama-hydroxy carboxylic acid usawoti, ama-polyol izakhiwo, ama-polyoxylenenenene netivatives ngokwazo Amakhemikhali Main izakhi.
Yini indlela yokwenza amanzi anciphisa?
Wonke ama-ejenti anciphise amanzi angaphezulu kwama-ejenti asebenzayo. Umphumela wokunciphisa amanzi we-ejenti yokunciphisa amanzi utholwa ikakhulukazi ngumsebenzi ongaphezulu wamanzi anciphisa i-ejenti. Indlela esemqoka yokunciphisa amanzi ngokulandelayo:
1) Amanzi anciphise ama-adsorb esibonakalayo esibonakalayo esiqinile, anciphise ukungezwani komhlaba, athuthukise ubumbano lwezinhlayiya zensimbi, banciphise ukungazinzisi komasimende, futhi ngaleyo ndlela bathole ukuqina okuhlobene.
2) Amanzi anciphisa amanzi azokhiqiza ama-adsorption aqondisayo ebusweni bezinhlayiya zokwenza usimende, ukuze ingaphezulu lezinhlayiya zensimbi lizoba necala elifanayo, likhiqize ukuphazamiseka kwe-electrostatic, ngaleyo ndlela libhubhise ukwakheka kwe-flocculatic zezinhlayiya zokwenza usimende kanye nezinhlanzi ezihlakazekile. Okwe-polycarboxxylate kanye ne-sulfatate superplastifizer, i-adsorption ye-superplastizer isesimweni sendandatho, ngocingo kanye nokwandisa ibanga phakathi kokuxoshwa komoya, okubonisa ukusakazwa okungcono nokugcinwa okungcono.
3) Ifilimu lamanzi elihlanganisiwe lenziwa nge-hydrogen bond association phakathi kokunciphiswa kwamanzi kanye nama-molecule amanzi ukukhiqiza ukuvikela isikhala, ukuvikela ukuxhumana okuqondile kwezinhlayiya zensimbi.
4) Njengoba kusungulwa ungqimba lwe-adsorption ebusweni bezinhlayiya zokwenza usimende, kungavimba i-hydration yokuqala ka usimende, ngaleyo ndlela ukwandisa ivolumu yamanzi yamahhala kanye nokwenza ngcono uketshezi lukasimende unamathisele.
5) Amanye ama-ejenti anciphise amanzi azokwethula inani elithile lama-bubble amancane ukunciphisa ukungezwani phakathi kwezinhlayiya kasimende, ngaleyo ndlela kuthuthukiswe ukuhlakazwa kanye nokuqina kwesimende slurry.
