Umahluko phakathi kwePlasticizer kunye neSuperplasticizer

Iiplastiki kunye ne-superplasticizers zombini iindidi zezongezo zekhemikhali ezisetyenziswa kwimixube yekhonkrithi ukuphucula ukusebenza, ukunciphisa umthamo wamanzi, kunye nokuphucula iimpawu ezithile zekhonkrithi. Nangona kunjalo, ziyahluka kwiindlela zabo zokwenza kunye neenzuzo ezithile ababonelela ngazo. Nantsi umahluko ophambili phakathi kweeplasticizers kunye ne-superplasticizers:

1. Indlela yokwenza:
   • I-Plasticizers: I-Plasticizers yi-soluble yamanzi e-organic compounds edibeneyo kunye ne-surface ye-cement particles, ukunciphisa amandla okutsala i-interparticle kunye nokuphucula ukusabalalisa kweengqungquthela ze-samente kumxube. Basebenza ngokuyinhloko ngokuthambisa amasuntswana, okuvumela ulwelo olukhulu kunye nokuphathwa lula komxube wekhonkrithi.
   • I-Superplasticizers: I-Superplasticizers, eyaziwa ngokuba yi-high-range water reducers (HRWR), i-agent esebenzayo kakhulu yokunciphisa amanzi esasaza amaqhekeza e-samente ngokufanelekileyo ngaphezu kweeplastiki. Basebenza ngokubhengeza kumphezulu weengqungquthela zesamente kunye nokwenza ifilimu encinci, eyenza amandla anamandla aphikisayo phakathi kwamaqhekeza, ngaloo ndlela ukunciphisa umlinganiselo wamanzi ukuya kwi-samente ngaphandle kokuphazamisa ukusebenza.
2. Ukunciphisa Amanzi:
   • IiPlastiki: IiPlastiki zinciphisa umthamo wamanzi kwimixube yekhonkrithi nge-5% ukuya kwi-15% ngelixa zigcina ukusebenza.
   • I-Superplasticizers: Ii-Superplasticizers zinokufikelela kumanqanaba aphezulu okucutha kwamanzi, ngokuqhelekileyo kuluhlu lwe-20% ukuya kwi-40%, okuvumela ukuphuculwa okubalulekileyo kumandla okhonkrithi, ukuqina, kunye nokusebenza.
3. Umthamo:
   • IiPlastiki: Iiplasticizers ziqhele ukusetyenziswa kwiidosi ezisezantsi xa kuthelekiswa ne-superplasticizers ngenxa yesakhono sazo esiphakathi sokunciphisa amanzi.
   • I-Superplasticizers: Ii-superplasticizers zifuna iidosi eziphezulu ukufezekisa ukucuthwa kwamanzi afunekayo kwaye zihlala zisetyenziswa ngokudibeneyo kunye nezinye izixube zokwandisa ukusebenza.
4. Isiphumo sokuSebenza:
   • IiPlastiki: Iiplastiki ngokuyinhloko ziphucula ukusebenza kunye nokuhamba kwemixube yekhonkrithi, okwenza kube lula ukuyibeka, i-compact, kunye nokugqiba.
   • I-Superplasticizers: Ii-Superplasticizers zibonelela ngeenzuzo ezifanayo kwiiplastiki kodwa zinokufikelela kumanqanaba aphezulu okusebenza kunye nokuhamba, okuvumela ukuveliswa kwemixube yekhonkrithi emanzi kakhulu kunye nokuzihlanganisa.
5. Usetyenziso:
   • Iiplastiki: Iiplastiki zisetyenziswa ngokuqhelekileyo kwiinkqubo ezininzi zekhonkrithi apho ukuphuculwa kokusebenza kunye nokulula kokuphatha kufunwayo, njengekhonkrithi esele ilungile, ikhonkrithi ekhonkrithiweyo, kunye ne-shotcrete.
   • I-Superplasticizers: Ii-Superplasticizers zihlala zisetyenziswa kwimixube yekhonkrithi esebenza kakhulu apho amandla aphezulu, ukuqina, kunye neempawu zokuhamba zifuneka, njengakwizakhiwo eziphakamileyo, iibhulorho kunye neeprojekthi zeziseko.

Isishwankathelo, ngelixa zombini iiplasticizers kunye ne-superplasticizers zisetyenziselwa ukuphucula ukusebenza kunye nokusebenza kwemixube yekhonkrithi, i-superplasticizers inika amandla amakhulu okunciphisa amanzi kwaye isetyenziswa ngokuqhelekileyo kwizicelo zekhonkrithi ezisebenza kakhulu apho amandla akhethekileyo, ukuqina, kunye nokuhamba kubalulekile.
