Lub luag haujlwm ntawm pob zeb superplasticizer
Nov 28, 2022
1. Yog tsis hloov qhov sib piv ntawm ntau yam raw cov ntaub ntawv, ntxiv high-efficiency qhob dej reducer yuav tsis hloov lub zog ntawm cov pob zeb, thiab tuaj yeem txhim kho cov rheology thiab plasticity ntawm cov pob zeb, kom cov pob zeb ua vaj tse tuaj yeem ua rau nws tus kheej ntws, twj, Tsis tas yuav muaj kev vibration thiab lwm txoj hauv kev los ua kev tsim kho, uas txhim kho kev tsim kho ceev thiab txo kev siv hluav taws xob siv.
2. Yog tsis hloov qhov piv ntawm ntau yam raw cov ntaub ntawv (dej tshem tawm) thiab slump ntawm pob zeb, txo cov dej yuav ua tau zoo heev txhim kho lub zog ntawm pob zeb. Lub zog thaum ntxov thiab tom qab lub zog yog feem ntau siab dua cov uas tsis muaj dej reducer Lub pob zeb yog nce 60 feem pua los yog ntau tshaj 20 feem pua, thiab los ntawm kev txo cov dej, nws muaj peev xwm ncuav C100 high-strength pob zeb.
3. Yog tias tsis hloov qhov piv ntawm ntau yam khoom siv raw (tshwj tsis yog cov cement) thiab lub zog ntawm cov pob zeb, cov cement tuaj yeem txo. Ntxiv 0.2 feem pua rau 0.5 feem pua ntawm cov cement loj ntawm cov pob zeb ua dej reducer tuaj yeem txuag tau 15 feem pua ntawm cov cement ntau tshaj 30 feem pua.
4. Ntxiv cov dej ua kom muaj txiaj ntsig zoo rau cov pob zeb tuaj yeem ua rau lub neej kev pab cuam ntawm pob zeb ntau dua ob npaug, txawm tias lub neej ua haujlwm ntawm lub tsev tuaj yeem txuas ntxiv tau ntau dua ob npaug.
Tam sim no, kev siv cov polycarboxylate superplasticizers hauv kev tsim kho vaj tsev tseem muaj ntau. Qhov no yog vim nws cov khoom ua tau zoo tuaj yeem txhim kho lub zog thiab txhim kho qhov project zoo. Cov khoom no yog ib puag ncig tus phooj ywg, tsis muaj nplaim taws, tsis tawg, thiab tuaj yeem siv tau zoo hauv tsheb ciav hlau thiab tsheb thauj mus los. Yog li ntawd, nws ua lub luag haujlwm tseem ceeb hauv kev tsim vaj tsev, thiab nws cov txiaj ntsig tau qhia hauv qab no.
1. Cov ntsiab lus alkali thiab cov ntsiab lus chloride ion tsawg heev. Tom qab polycarboxylate niam cawv yog tov, nws yuav tsis corrode steel bar thiab tsis muaj kev cuam tshuam rau cov pob zeb. Nyob rau tib lub sijhawm, cov khoom tsis ntsev tawm los yog crystallize nyob rau hauv lub caij ntuj no kub, thiab yog ib qho yooj yim mus use.
2. Nws yog qhov zoo los txhim kho kev ua haujlwm ntawm cov pob zeb sib tov, txo cov ntshav, txhim kho cov tsos zoo thiab ua haujlwm ntev ntawm cov pob zeb tawv tawv, tshwj xeeb tshaj yog tsim nyog rau kev siv hauv kev ua vaj tse ncaj ncees.
3. Txawm tias nyob rau hauv cov ntaub ntawv ntawm kev poob siab, cov pob zeb npaj nrog polycarboxylate superplasticizer niam cawv yuav tsis muaj kev sib cais thiab los ntshav tshwm sim, thiab cov tsos thiab xim ntawm cov pob zeb yuav zoo ib yam. Thaum siv los npaj cov pob zeb qib siab, cov pob zeb muaj kev ua haujlwm zoo, kev sib koom ua ke zoo, thiab cov pob zeb sib xyaw yooj yim.
Yog li ntawd, polycarboxylate dej reducer yog qhov tsim nyog rau kev tsim vaj tsev. Nws yog feem ntau ntxiv rau hauv kev faib ua feem thaum siv. Qhov no tuaj yeem tsis tsuas yog ua rau qhov project muaj zog tab sis kuj txo ntau yam kev phom sij. Peb tsuas yog yuav tsum nkag siab txog cov khoom siv thiab qhov zoo. Koj yuav tau siv nws zoo dua tom qab. Polycarboxylate superplasticizer yog ib qho kev ua tau zoo superplasticizer thiab cov cement dispersant siv hauv cov cement pob zeb. Dav siv nyob rau hauv txoj kev loj, txuas hniav, dams, tunnels, high-sawv vaj tse thiab lwm yam dej num.
