Umahluko Phakathi kwePlasticizer kunye neSuperplasticizer

Iiplastiki kunye nee-superplasticizer zombini ziintlobo zezithako zeekhemikhali ezisetyenziswa kwimixube yekhonkrithi ukuphucula ukusebenza kakuhle, ukunciphisa umthamo wamanzi, kunye nokuphucula iimpawu ezithile zekhonkrithi. Nangona kunjalo, zahlukile kwindlela yazo yokusebenza kunye neenzuzo ezithile ezizibonelelayo. Nazi umahluko ophambili phakathi kweeplastiki kunye nee-superplasticizer:

1. Indlela Yokusebenza:
   • Iiplastiki: Iiplastiki ziikhompawundi eziphilayo ezinyibilikayo emanzini ezisebenzisana nomphezulu weenxalenye zesamente, zinciphisa amandla okutsalana phakathi kweenxalenye kwaye ziphucula ukusasazeka kweenxalenye zesamente kumxube. Zisebenza ngokuyintloko ngokuthambisa iinxalenye, nto leyo evumela ukuba umxube wesamente ube lula kwaye kube lula ukuwuphatha.
   • IiSuperplasticizers: IiSuperplasticizers, ezaziwa ngokuba zii-high-range water reducers (HRWR), zizinto ezisebenzayo kakhulu zokunciphisa amanzi ezisasaza amasuntswana esamente ngokufanelekileyo kuneeplasticizers. Zisebenza ngokufunxa phezu kwamasuntswana esamente kwaye zenze ifilimu encinci, edala amandla amakhulu okugxotha phakathi kwamasuntswana, ngaloo ndlela kunciphisa umlinganiselo wamanzi nesamente ngaphandle kokuphazamisa ukusebenza.
2. Ukunciphisa Amanzi:
   • Iiplastiki: Iiplastiki zihlala zinciphisa umthamo wamanzi kwimixube yekhonkrithi nge-5% ukuya kwi-15% ngelixa zigcina ukusebenza kakuhle.
   • IiSuperplasticizers: IiSuperplasticizers zinokufikelela kumanqanaba aphezulu okunciphisa amanzi, ngokuqhelekileyo ukusuka kwi-20% ukuya kwi-40%, okuvumela ukuphuculwa okukhulu kwamandla ekhonkrithi, ukuqina kwayo, kunye nokusebenza kwayo.
3. Idosi:
   • Iiplastiki: Iiplastiki zihlala zisetyenziswa ngeedosi eziphantsi xa kuthelekiswa nee-superplasticizer ngenxa yokuba zikwazi ukunciphisa amanzi ngendlela ephakathi.
   • IiSuperplasticizers: IiSuperplasticizers zifuna iidosi eziphezulu ukuze kufezekiswe ukuncitshiswa kwamanzi okufunekayo kwaye zihlala zisetyenziswa kunye nezinye izinto ezidityanisiweyo ukuphucula ukusebenza.
4. Impembelelo ekusebenzeni kakuhle:
   • Iiplastiki: Iiplastiki ziphucula ukusebenza kakuhle kunye nokuhamba kakuhle kwemixube yekhonkrithi, nto leyo eyenza kube lula ukuyibeka, ukuyicoca, kunye nokuyigqiba.
   • IiSuperplasticizers: IiSuperplasticizers zibonelela ngeenzuzo ezifanayo kwiiplasticizers kodwa zinokufikelela kumanqanaba aphezulu okusebenza nokuhamba kakuhle, okuvumela ukuveliswa kwemixube yekhonkrithi emanzi kakhulu neyazidibanisa ngokwayo.
5. Izicelo:
   • Iiplastiki: Iiplastiki zisetyenziswa kakhulu kwiintlobo ngeentlobo zezicelo zekhonkrithi apho kufuneka kuphuculwe ukusebenza kwayo kunye nokuphathwa kwayo, njengekhonkrithi exutywe kakuhle, ikhonkrithi elungisiweyo, kunye ne-shotcrete.
   • IiSuperplasticizers: IiSuperplasticizers zihlala zisetyenziswa kwimixube yekhonkrithi esebenza kakhulu apho kufuneka khona amandla aphezulu, ukuqina, kunye neempawu zokuhamba kwamanzi, njengakwizakhiwo eziphakamileyo, iibhulorho, kunye neeprojekthi zeziseko zophuhliso.

Ngamafutshane, nangona zombini iiplastiki kunye nee-superplasticizers zisetyenziselwa ukuphucula ukusebenza kakuhle kunye nokusebenza kwemixube yekhonkrithi, ii-superplasticizers zibonelela ngamandla amakhulu okunciphisa amanzi kwaye zisetyenziswa kakhulu kwizicelo zekhonkrithi ezisebenza kakhulu apho amandla angaqhelekanga, ukuqina, kunye nokuhamba kwamanzi kubalulekile.
