Phapang lipakeng tsa Plasticizer le Superplasticizer

Li-plasticizers le li-superplasticizers ke mefuta e 'meli ea li-additives tsa lik'hemik'hale tse sebelisoang ka motsoako oa konkreite ho ntlafatsa ts'ebetso, ho fokotsa metsi le ho ntlafatsa thepa e itseng ea konkreite. Leha ho le joalo, li fapane ka mekhoa ea bona ea ts'ebetso le melemo e tobileng eo ba fanang ka eona. Mona ke phapang ea bohlokoa lipakeng tsa li-plasticizers le li-superplasticizers:

1. Mokhoa oa ts'ebetso:
   • Plasticizers: Li-plasticizers ke metsoako ea lintho tse phelang tse qhibilihang ka metsing tse sebelisanang le bokaholimo ba likaroloana tsa samente, ho fokotsa matla a ho hohela le ho ntlafatsa ho hasana ha likaroloana tsa samente motsoakong. Ba sebetsa haholo-holo ka ho tlotsa likaroloana, e leng se lumellang hore ho be le metsi a mangata le ho sebetsana habonolo le motsoako oa konkreite.
   • Li-Superplasticizers: Li-Superplasticizers, tse tsejoang hape e le li-high-range water reducers (HRWR), ke lisebelisoa tse fokotsang metsi tse atlehang haholo tse qhalang likaroloana tsa samente ka katleho ho feta li-plasticizers. Ba sebetsa ka ho bapatsa ka holim'a likaroloana tsa samente le ho etsa filimi e tšesaane, e leng se etsang hore ho be le matla a matla a ho nyenyefatsa pakeng tsa likaroloana, kahoo ho fokotsa tekanyo ea metsi le samente ntle le ho sekisetsa ho sebetsa.
2. Phokotso ea Metsi:
   • Li-plasticizers: Hangata li-plasticizers li fokotsa metsi a motsoako oa konkreite ka 5% ho isa ho 15% ha li ntse li boloka ho sebetsa.
   • Li-Superplasticizers: Li-Superplasticizers li ka fihlela maemo a phahameng a phokotso ea metsi, hangata ho tloha ho 20% ho isa ho 40%, e leng se lumellang ntlafatso e kholo ea matla a konkreite, ho tšoarella le ts'ebetso.
3. Tekanyetso:
   • Li-plasticizers: Hangata li-plasticizers li sebelisoa ka litekanyetso tse tlase ha li bapisoa le li-superplasticizers ka lebaka la bokhoni ba tsona ba ho fokotsa metsi.
   • Li-superplasticizers: Li-superplasticizers li hloka litekanyetso tse phahameng ho fihlela phokotso ea metsi e lakatsehang, 'me hangata li sebelisoa hammoho le li-admixtures tse ling ho ntlafatsa ts'ebetso.
4. Phello ho Mosebetsi:
   • Li-Plasticizers: Li-plasticizers li ntlafatsa haholo ts'ebetso le ho phalla ha metsoako ea konkreite, ho etsa hore ho be bonolo ho e beha, ho kopana le ho qeta.
   • Li-Superplasticizers: Li-Superplasticizers li fana ka melemo e ts'oanang ho li-plasticizers empa li ka finyella maemo a phahameng a ho sebetsa le ho phalla, ho lumella ho hlahisa metsoako ea konkreite e nang le metsi a mangata le e ikemetseng.
5. Lisebelisoa:
   • Li-Plasticizers: Li-plasticizers li atisa ho sebelisoa mefuteng e mengata ea konkreite moo ho hlokahalang ho ntlafatsa ts'ebetso le boiketlo ba ho tšoara, joalo ka konkreite e itokiselitseng, konkreite ea precast, le shotcrete.
   • Li-Superplasticizers: Li-superplasticizers li atisa ho sebelisoa ka metsoako ea konkreite e sebetsang hantle moo ho hlokahalang matla a holimo, ho tšoarella nako e telele, le litšoaneleho tsa phallo, joalo ka mehahong e phahameng, marokho le merero ea mehaho.

Ka kakaretso, le hoja li-plasticizers le li-superplasticizers li sebelisetsoa ho ntlafatsa ts'ebetso le ts'ebetso ea metsoako ea konkreite, li-superplasticizers li fana ka bokhoni bo boholo ba ho fokotsa metsi 'me li sebelisoa ka ho fetisisa lits'ebetsong tsa konkreite tse sebetsang hantle moo matla a ikhethang, nako e telele le ho phalla ho leng bohlokoa.
