Umehluko Phakathi kwePlasticizer neSuperplasticizer

Ama-Plasticizer nama-superplasticizers yizinhlobo zombili zezithasiselo zamakhemikhali ezisetshenziswa ezixubeni zikakhonkolo ukuze kuthuthukiswe ukusebenza, ukunciphisa okuqukethwe kwamanzi, kanye nokuthuthukisa izici ezithile zikakhonkolo.Nokho, ziyehluka ezindleleni zazo zokusebenza kanye nezinzuzo ezithile ezizinikezayo.Nansi umehluko omkhulu phakathi kwama-plasticizers nama-superplasticizers:

1. Indlela Yesenzo:
   • Ama-Plasticizers: Ama-Plasticizers angama-organic-soluble organic compounds asebenzisana nobuso bezinhlayiya zikasimende, anciphisa amandla okukhanga kwezinhlayiyana futhi athuthukise ukuhlakazeka kwezinhlayiya zikasimende ekuxubeni.Basebenza ngokuyinhloko ngokugcoba izinhlayiya, okuvumela uketshezi olukhulu nokuphatha kalula ingxube kakhonkolo.
   • Ama-Superplasticizers: Ama-Superplasticizers, aziwa nangokuthi ama-high-range water reducers (HRWR), ama-ejenti anciphisa amanzi asebenza kahle kakhulu ahlakaza izinhlayiya zikasimende ngokuphumelelayo kunamaplastiki.Zisebenza ngokukhangisa phezu kwezinhlayiya zikasimende futhi zenze ifilimu elincanyana, elidala amandla aqinile anyanyekayo phakathi kwezinhlayiya, ngaleyo ndlela kuncishiswe isilinganiso samanzi ukuya kusimende ngaphandle kokuphazamisa ukusebenza.
2. Ukuncishiswa kwamanzi:
   • Ama-Plasticizer: Ama-Plasticizer ngokuvamile anciphisa okuqukethwe kwamanzi okuxubene nokhonkolo ngo-5% kuya ku-15% kuyilapho egcina ukusebenza.
   • Ama-Superplasticizers: Ama-Superplasticizers angafinyelela amazinga aphezulu okunciphisa amanzi, ngokuvamile ebangeni elingama-20% kuya ku-40%, okuvumela ukuthuthukiswa okuphawulekayo kumandla kakhonkolo, ukuqina, nokusebenza.
3. Umthamo:
   • Ama-Plasticizers: Ama-Plasticizers ngokuvamile asetshenziswa ngemithamo ephansi uma kuqhathaniswa nama-superplasticizers ngenxa yamakhono azo okunciphisa amanzi amaphakathi.
   • Ama-Superplasticizers: Ama-Superplasticizers adinga imithamo ephezulu ukuze afinyelele ukuncishiswa kwamanzi okufunayo futhi avame ukusetshenziswa ngokuhlanganiswa nezinye izixube ukwenza ukusebenza kahle.
4. Umthelela Ekusebenzeni:
   • Ama-Plasticizer: Ama-Plasticizer athuthukisa ukusebenza kahle nokugeleza kwezingxube zikakhonkolo, azenze kube lula ukuzibeka, ukubumbana, nokuqeda.
   • Ama-Superplasticizers: Ama-Superplasticizers ahlinzeka ngezinzuzo ezifanayo kuma-plasticizers kodwa angafinyelela amazinga aphezulu okusebenza nokugeleza, okuvumela ukukhiqizwa kwezingxube zikakhonkolo ezimanzi kakhulu nezizihlanganisayo.
5. Izicelo:
   • Ama-Plasticizers: Ama-Plasticizers avame ukusetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza zekhonkrithi lapho kufunwa khona ukusebenza okuthuthukisiwe nokulula ukuphatha, njengokhonkolo olungele ukuxuba, ukhonkolo owenziwe ngaphambili, kanye ne-shotcrete.
   • Ama-Superplasticizers: Ama-Superplasticizers avame ukusetshenziswa ezixubeni zikakhonkolo ezisebenza kahle lapho kudingeka khona amandla aphakeme, ukuqina, nezici zokugeleza, njengasezindaweni eziphakeme kakhulu, amabhuloho, namaphrojekthi engqalasizinda.

Kafushane, ngenkathi kokubili ama-plasticizers nama-superplasticizers asetshenziselwa ukuthuthukisa ukusebenza nokusebenza kwezingxube zikakhonkolo, ama-superplasticizers anikeza amandla amakhulu okunciphisa amanzi futhi avame ukusetshenziswa kakhulu ekusetshenzisweni kokhonkolo okusebenza okuphezulu lapho amandla angavamile, ukuqina, nokugeleza kubalulekile.
