Taw qhia:
Cov khoom siv zoo tshaj plaws pab txhim kho cov pob zeb ua kom muaj zog thiab ua tau zoo, muab cov dej nruj thiab tiv thaiv cov pob zeb ua los ntawm atmospheric degradation.
Nta:
1. Kev poob me me thaum qhov poob qis yog lub teeb: 2h slump poob ntawm premixed pob zeb yog tsawg dua 15 feem pua, uas muaj txiaj ntsig zoo rau kev thauj mus los ntev thiab siv cov pob zeb ua lag luam.
2. Cov khoom siv zoo tshaj plaws muaj kev ua haujlwm zoo rau kev ua vaj tse: txawm tias nyob rau hauv cov ntaub ntawv ntawm kev poob siab, cov pob zeb npaj nrog PC polycarboxylate superplasticizer yuav tsis tshwm sim pom kev sib cais thiab los ntshav, thiab cov pob zeb zoo li xim tsis sib xws. Nws yog qhov zoo heev rau kev npaj cov pob zeb ua haujlwm siab, nws tus kheej-leveling pob zeb, nws tus kheej-compacting pob zeb thiab nto-watered pob zeb. Thaum siv los tsim cov pob zeb qib siab, cov pob zeb muaj kev ua haujlwm zoo, kev sib koom ua ke zoo thiab sib xyaw yooj yim.
3, Cov khoom siv zoo tshaj plaws muaj cov pob zeb shrinkage: tuaj yeem txo cov pob zeb loj, ua kom cov pob zeb ntim ruaj khov thiab ua haujlwm ntev.
4. Cov ntsiab lus alkali tsawg heev: cov ntsiab lus alkali Tsawg dua lossis sib npaug rau 0.2 feem pua .
5. Kev ruaj ntseg zoo: tsis muaj nag lossis daus ntawm qhov kub thiab txias.
6. Cov txiaj ntsig zoo ntawm kev lag luam: tus nqi tsim nyog tau txais qis dua li ntawm lwm hom khoom.
Polycarboxylic acid dej txo tus neeg sawv cev yog ib yam ntawm cov khoom tiv thaiv ib puag ncig ntsuab, nws cov ntsiab lus alkali, cov ntsiab lus chloride ion, sodium sulfate cov ntsiab lus, cov ntsiab lus formaldehyde tsawg heev, thiab nyob rau hauv cov txheej txheem ntau lawm tsis tsim muaj kuab paug rau lub ntuj ib puag ncig, conducive rau sustainable kev loj hlob. .
Teb:
Nws yog tsim rau prefabrication thiab pouring ntawm reinforced qhob nyob rau hauv ntau yam industries, civil vaj tse, dej conservancy, tsheb thauj mus los, ports thiab municipal engineering.
Steam curing txheej txheem rau precast qhob Cheebtsam.
Dej-txo thiab txhawb cov khoom siv rau ntau yam kev sib xyaw ua ke
Cim npe nrov: High quality additive, manufacturers, lwm tus neeg, Hoobkas, nqi
