Hobaneng ha PCE Powder e sebetsa hantle ho SCC

Konkreite e iketsetsang (SCC) tlameha ho phalla habonolo ntle le molumo. E boetse e hloka ho lula o tsitsitse le ho se arohane. Ha SCC e na le likotlo tse ngata– joalo ka konkreite, fofa molora, kapa phofo ea majoe a sedimentary– ho fihla ho ba thata ho kopanya le ho beha maemo. That’s where PCE-based superplasticizers been available in. Metsoako ena e entsoe ka polycarboxylate ether (PCE) le ho sebetsa hantle ho feta mefuta ea khale.

E boetse e sebetsa hantle ha e kopana le lihlahisoa tse ngata tse eketsehileng tsa samente (Li-SCM). Tsena li na le slag kapa fly ash. Ho sebelisa li-SCM ho fokotsa litšenyehelo 'me ho molemo haholo bakeng sa tikoloho. Leha ho le joalo ba eketsa likotlo tse eketsehileng. PCE powder balances this by improving circulation without harming stability.

Molemo o eketsehileng o tsamaisana le ts'ebetso. PCE e arabela hantle ho samente le lihlahisoa tse fapaneng. Beha kamora ho seta, liphetho li lula li tšepahala. Bafani ba litšebeletso ba fumana nako e fokolang ea ho emisa le ho fokotsa litšila.

PCE phofo ke eng le hore na ke hobane'ng ha e sebelisoa ho SCC?

PCE phofo e emetse polycarboxylate ether superplasticizer. E thusa ho iketsetsa konkreite (SCC) ho phalla ha bonolo ntle le ho thothomela. Sena se bohlokoa ha motsoako oa hau o na le likaroloana tse ngata tse ntle joalo ka samente, fofa molora, kapa phofo ea mokoetla. Likotlo tsena li ka etsa hore motsoako o be thata. PCE phofo e boloka e le metsi ebile e sebetsa.

Phofo ea PCE e ntlafatsa joang ho phalla ha metsoako e phahameng ea lichelete?

Litefiso tse phahameng li eketsa botenya ba peista. Seo se etsa hore SCC e be thata ho e beha. PCE phofo e sebetsa ka ho roala likaroloana tsa samente. E ba arola ka bonolo. Sena se fokotsa likhohlano pakeng tsa likaroloana. Sephetho ke phallo e ntle le metsi a fokolang a hlokahalang. Konkreite ea hau e lula e tsitsitse ebile ha e arohane.

Na phofo ea PCE e ka baka tahlehelo e ngata haholo ea ho putlama ha nako e ntse e feta?

Lihlahisoa tse ling tsa PCE li ka lahleheloa ke katleho ka mor'a metsotso ea 30-60. Empa li-powders tsa morao-rao tsa PCE li etselitsoe ho sebetsa nako e telele.

Tekanyo e nepahetseng e boetse e thibela tahlehelo ea pele ea ho putlama.

Ke tekanyo efe e nepahetseng bakeng sa SCC e nang le likotlo tse phahameng?

Tekanyo e ipapisitse le lisebelisoa tsa hau le phallo ea sepheo. Qala ka 0.2% ho 0.4% ka boima ba ho kopanya kakaretso. Lekola lihlopha tse nyane pele. Ho fokola haholo ho fana ka phallo e mpe. Ho ja haholo ho ka baka mathata a ho tsoa mali kapa moea. Fetola ho latela liphetho tsa liteko le litlhoko tsa sebaka.
