Umehluko Phakathi Kwe-Plasticizer Ne-Superplasticizer

Ama-plasticizer nama-superplasticizer womabili ayizinhlobo zezithasiselo zamakhemikhali ezisetshenziswa ezingxubeni zekhonkrithi ukuthuthukisa ukusebenza kahle, ukunciphisa okuqukethwe kwamanzi, nokuthuthukisa izakhiwo ezithile zekhonkrithi. Kodwa-ke, ziyahlukahluka ngezindlela zazo zokusebenza kanye nezinzuzo ezithile ezinikezayo. Nansi umehluko oyinhloko phakathi kwama-plasticizer nama-superplasticizer:

1. Indlela Yokusebenza:
   • Ama-Plasticizer: Ama-Plasticizer ayizinto eziphilayo ezincibilika emanzini ezisebenzisana nobuso bezinhlayiya zesimende, zinciphisa amandla okukhanga phakathi kwezinhlayiya futhi zithuthukise ukuhlakazeka kwezinhlayiya zesimende engxubeni. Zisebenza ngokuyinhloko ngokugcoba izinhlayiya, okuvumela ukugeleza okukhulu kanye nokuphathwa okulula kwengxube yekhonkrithi.
   • Ama-Superplasticizer: Ama-Superplasticizer, aziwa nangokuthi ama-high-range water reducers (HRWR), angama-ejenti asebenza kahle kakhulu okunciphisa amanzi ahlakaza izinhlayiya zesimende ngendlela ephumelela kakhulu kune-plasticizers. Asebenza ngokunamathela ebusweni bezinhlayiya zesimende futhi akhe ifilimu encane, edala amandla amakhulu okuxosha phakathi kwezinhlayiya, ngaleyo ndlela kunciphisa isilinganiso samanzi nosimende ngaphandle kokubeka engcupheni ukusebenza kahle.
2. Ukunciphisa Amanzi:
   • Ama-Plasticizer: Ama-Plasticizer ngokuvamile anciphisa okuqukethwe kwamanzi kwezingxube zekhonkrithi ngo-5% kuya ku-15% ngenkathi egcina ukusebenza kahle.
   • Ama-Superplasticizer: Ama-Superplasticizer angafinyelela amazinga aphezulu okunciphisa amanzi, ngokuvamile aphakathi kuka-20% kuya ku-40%, okuvumela ukuthuthukiswa okukhulu emandleni ekhonkrithi, ukuqina, kanye nokusebenza.
3. Isilinganiso:
   • Ama-Plasticizer: Ama-Plasticizer avame ukusetshenziswa ngemithamo ephansi uma kuqhathaniswa nama-superplasticizer ngenxa yamandla awo okunciphisa amanzi aphakathi nendawo.
   • Ama-Superplasticizer: Ama-Superplasticizer adinga imithamo ephezulu ukuze kufezwe ukuncishiswa kwamanzi okufunwayo futhi avame ukusetshenziswa kanye nezinye izingxube ukuze kuthuthukiswe ukusebenza.
4. Umphumela Ekusebenzeni Kahle:
   • Ama-Plasticizer: Ama-Plasticizer athuthukisa kakhulu ukusebenza kahle kanye nokugeleza kahle kwezingxube zekhonkrithi, okwenza kube lula ukuzibeka, ukuzihlanganisa, kanye nokuziqeda.
   • Ama-Superplasticizer: Ama-Superplasticizer anikeza izinzuzo ezifanayo kuma-plasticizer kodwa angafinyelela amazinga aphezulu okusebenza kahle nokugeleza kahle, okuvumela ukukhiqizwa kwezingxube zekhonkrithi ezinoketshezi oluningi nezizihlanganisayo.
5. Izicelo:
   • Ama-Plasticizer: Ama-Plasticizer avame ukusetshenziswa ezinhlobonhlobo zezicelo zekhonkrithi lapho kudingeka khona ukusebenza okuthuthukisiwe kanye nokulula kokuphathwa, njengekhonkrithi exutshwe ngomumo, ikhonkrithi elungisiwe, kanye ne-shotcrete.
   • Ama-Superplasticizer: Ama-Superplasticizer avame ukusetshenziswa ezingxubeni zekhonkrithi ezisebenza kahle kakhulu lapho kudingeka khona amandla aphezulu, ukuqina, kanye nezici zokugeleza, njengasezakhiweni eziphakeme, amabhuloho, kanye namaphrojekthi engqalasizinda.

Ngamafuphi, nakuba kokubili ama-plasticizer nama-superplasticizer esetshenziswa ukuthuthukisa ukusebenza kahle nokusebenza kwezingxube zekhonkrithi, ama-superplasticizer anikeza amandla amakhulu okunciphisa amanzi futhi avame ukusetshenziswa kakhulu ekusetshenzisweni kwekhonkrithi esebenza kahle lapho amandla akhethekile, ukuqina, kanye nokugeleza kwamanzi kubalulekile.
