Phapang Pakeng tsa Plasticizer le Superplasticizer

Li-plasticizer le li-superplasticizer ka bobeli ke mefuta ea lik'hemik'hale tse sebelisoang metsoakong ea konkreite ho ntlafatsa ho sebetsa hantle, ho fokotsa metsi, le ho ntlafatsa litšobotsi tse itseng tsa konkreite. Leha ho le joalo, li fapana ka mekhoa ea tsona ea ts'ebetso le melemo e itseng eo li fanang ka eona. Mona ke liphapang tsa bohlokoa lipakeng tsa li-plasticizer le li-superplasticizer:

1. Mokhoa oa Ketso:
   • Li-plasticizer: Li-plasticizer ke metsoako ea lintho tse phelang e qhibilihang ka metsing e sebelisanang le bokaholimo ba likaroloana tsa samente, e fokotsang matla a ho hohela lipakeng tsa likaroloana le ho ntlafatsa ho hasana ha likaroloana tsa samente motswakong. Li sebetsa haholo-holo ka ho tlotsa likaroloana, e leng se lumellang ho phalla ha mokelikeli o moholo le ho sebetsana habonolo ha motsoako oa konkreite.
   • Li-Superplasticizer: Li-Superplasticizer, tse tsejoang hape e le li-high-range water reducers (HRWR), ke lisebelisoa tse sebetsang hantle haholo tse fokotsang metsi tse hasanyang likaroloana tsa samente ka katleho ho feta li-plasticizer. Li sebetsa ka ho monya holim'a likaroloana tsa samente le ho etsa filimi e tšesaane, e leng se hlahisang matla a matla a nyonyehang pakeng tsa likaroloana, ka hona li fokotsa karolelano ea metsi le samente ntle le ho beha kotsing ea ho sebetsa.
2. Phokotso ea Metsi:
   • Li-plasticizer: Hangata li-plasticizer li fokotsa metsi a metsoako ea konkreite ka 5% ho isa ho 15% ha li ntse li boloka matla a ho sebetsa.
   • Li-Superplasticizer: Li-Superplasticizer li ka finyella maemo a holimo a phokotso ea metsi, hangata li pakeng tsa 20% le 40%, e leng se lumellang ntlafatso e kholo matleng a konkreite, ho tšoarella le ts'ebetso.
3. Tekanyo:
   • Li-plasticizer: Li-plasticizer hangata li sebelisoa ka tekanyo e tlase ha li bapisoa le li-superplasticizer ka lebaka la bokhoni ba tsona bo itekanetseng ba ho fokotsa metsi.
   • Li-Superplasticizer: Li-Superplasticizer li hloka litekanyo tse phahameng ho fihlela phokotso e lakatsehang ea metsi 'me hangata li sebelisoa hammoho le metsoako e meng ho ntlafatsa ts'ebetso.
4. Tšusumetso ho Bokhoni ba ho Sebetsa:
   • Li-plasticizer: Li-plasticizer li ntlafatsa haholo-holo ho sebetsa le ho phalla ha metsoako ea konkreite, e leng se etsang hore ho be bonolo ho e beha, ho e kopanya le ho e qeta.
   • Li-Superplasticizer: Li-Superplasticizer li fana ka melemo e tšoanang le li-plasticizer empa li ka finyella maemo a holimo a ho sebetsa le ho phalla habonolo, e leng se lumellang tlhahiso ea metsoako ea konkreite e metsi haholo le e ikamahanyang.
5. Likopo:
   • Li-plasticizer: Li-plasticizer li sebelisoa hangata lits'ebetsong tse fapaneng tsa konkreite moo ho hlokahalang hore ho be bonolo ho sebetsa le ho sebetsana le tsona, joalo ka konkreite e kopantsoeng hantle, konkreite e entsoeng esale pele, le shotcrete.
   • Li-Superplasticizer: Li-Superplasticizer hangata li sebelisoa mefuteng ea konkreite e sebetsang hantle moo ho hlokahalang matla a phahameng, ho tšoarella le litšobotsi tsa phallo, joalo ka mehahong e meholo, marokho le merero ea meralo ea motheo.

Ka bokhutšoanyane, leha li-plasticizer le li-superplasticizer li sebelisoa ho ntlafatsa bokhoni ba ho sebetsa le ts'ebetso ea metsoako ea konkreite, li-superplasticizer li fana ka bokhoni bo boholo ba ho fokotsa metsi 'me li sebelisoa haholo lits'ebetsong tsa konkreite tse sebetsang hantle moo matla a ikhethang, ho tšoarella le ho phalla ha metsi li leng bohlokoa.
