Khoom Description
PCE Polycarboxylate Ether li Concrete Admixture Polycarboxylate Superplasticizer yog cov dej ua haujlwm siab thiab cov cement dispersant hauv cov cement pob zeb. Nws yog dav siv nyob rau hauv txoj kev loj, txuas hniav, dams, tunnels, high-sawv vaj tse thiab lwm yam dej num. Cov khoom no yog ntsuab thiab ib puag ncig tus phooj ywg, tsis muaj hluav taws kub, tsis tawg, thiab tuaj yeem thauj mus los ntawm tsheb ciav hlau thiab tsheb.
Raws li cov txheej txheem sib txawv ntawm cov saw hlau, PCE Polycarboxylate Ether li Cov Khoom Siv Khoom Siv Khoom Siv Polycarboxylate superplasticizer tuaj yeem muab faib ua ob pawg: ib qho yog raws li acrylic acid lossis methacrylic acid ua cov saw tseem ceeb, thiab grafted nrog polyethers ntawm cov saw sib txawv ntev. Lwm qhov yog raws li cov txiv neej anhydride ua cov saw tseem ceeb thiab grafted nrog polyethers ntawm ntau sab saw ntev. Raws li qhov no, cov khoom ua tau zoo ntawm cov dej reducer nrog cov yam ntxwv sib txawv tau muab los.
Ua ntej qhov tshwm sim ntawm polycarboxylate admixtures PCE Polycarboxylate Ether li Concrete Admixture, muaj lignin sulfonate admixtures, naphthalene sulfonate formaldehyde condensates, melamine formaldehyde condensates, acetone sulfonate formaldehyde condensates, Japanese sulfonate, thiab lwm yam coj tus thawj coj ua tiav tsim cov polycarboxylate superplasticizers. Cov tiam tshiab ntawm polycarboxylic acid-raws li high-efficiency dej-txo cov neeg ua haujlwm tau kov yeej qee qhov tsis zoo ntawm cov tshuaj txo cov dej thiab muaj qhov zoo ntawm cov khoom siv tsawg, kev ua haujlwm zoo hauv lub cev, tsis tshua muaj pob zeb shrinkage, muaj zog adjustability hauv molecular qauv, muaj peev xwm zoo rau kev ua haujlwm siab, thiab tsis siv formaldehyde hauv cov txheej txheem ntau lawm.
Cov Khoom Zoo
1. Zoo compatibility nrog ntau yam cements, zoo slump retention kev ua tau zoo ntawm pob zeb, thiab ncua sij hawm tsim kho ntawm pob zeb.
2. Tsawg npaum li cas, txo cov dej siab, thiab me me shrinkage.
3. Zoo heev txhim kho lub zog thaum ntxov thiab lig ntawm pob zeb.
4. Cov khoom no muaj cov ntsiab lus chloride ion tsawg thiab cov ntsiab lus tsis tshua muaj alkali, uas muaj txiaj ntsig zoo rau kev ua haujlwm ntev ntawm pob zeb.
5. Cov txheej txheem tsim khoom ntawm cov khoom no tsis muaj kuab lom thiab tsis muaj formaldehyde. Nws ua raws li ISO14000 tus qauv thoob ntiaj teb rau kev tswj hwm kev tiv thaiv ib puag ncig thiab yog cov khoom lag luam ntsuab thiab ib puag ncig zoo.
6. Siv polycarboxylate dej reducers, ntau slag lossis ya tshauv tuaj yeem siv los hloov cov cement, yog li txo cov nqi.
Cov khoom siv
PCE Polycarboxylate Ether li Concrete Admixture Polycarboxylate Superplasticizer yog tsim rau precast thiab cam khwb cia-nyob rau hauv-qhov chaw pob zeb, reinforced pob zeb thiab prestressed qhob nyob rau hauv kev tsim kho ntawm high-ceev railways, neeg nrog caij nplooj siab kab, industrial thiab pej xeem vaj tse, txoj kev, txuas hniav, chaw nres nkoj, tshav dav hlau thiab lwm qhov project.
PCE Polycarboxylate Ether li Concrete Admixture Polycarboxylate Superplasticizer yog tshwj xeeb tshaj yog haum rau tej yaam num uas siv sij hawm ntev thiab siab yuav tsum tau rau pob zeb slump, xws li nuclear fais fab nroj tsuag.
Khoom noj khoom haus
Kev noj ntau npaum li cas: Feem ntau, qhov ntau npaum li cas yog {{0}}.5-1.5% ntawm qhov hnyav ntawm cov khoom cementitious thaum hloov mus rau 20% cov ntsiab lus, thiab cov lus pom zoo yog 1.0%.
