Khoom yam ntxwv

BD-501 dej-txo polycarboxylate dej reducer niam cawv: Polycarboxylate Superplasticizer yog cov dej-txo cov neeg ua haujlwm siab thiab cov cement dispersant hauv kev siv 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.

Cov khoom yog ntsuab thiab ib puag ncig tus phooj ywg, tsis muaj hluav taws kub thiab tsis tawg, thiab tuaj yeem thauj mus los ntawm tsheb ciav hlau thiab tsheb.

Khoom taw qhia

Raws li cov qauv sib txawv ntawm cov saw hlau, cov khoom siv polycarboxylate superplasticizer tuaj yeem muab faib ua ob pawg: ib qho yog polyether nrog acrylic acid lossis methacrylic acid ua cov saw tseem ceeb thiab grafted nrog cov saw sib txawv ntev. Lwm hom yog polyethers nrog maleic anhydride raws li cov saw tseem ceeb branched nrog sib txawv 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 polycarboxylic acid admixtures, muaj lignosulfonate admixtures, naphthalene sulfonate formaldehyde condensate, melamine formaldehyde polycondensate, acetone sulfonate formaldehyde condensate, sulfamate formaldehyde condensate thiab lwm yam. Thaum xyoo 1980, Nyiv tau ua tus thawj coj hauv kev tsim cov polycarboxylate superplasticizers. Cov tiam tshiab ntawm polycarboxylate superplasticizers overcomes ib co drawbacks ntawm tsoos superplasticizers, thiab muaj qhov zoo ntawm tsawg npaum li cas, zoo slump tuav, tsis tshua muaj pob zeb shrinkage, muaj zog molecular qauv adjustability, muaj peev xwm ua tau zoo, thiab muaj peev xwm ntau lawm. Cov txheej txheem tsis siv formaldehyde thiab lwm yam zoo.

Qhov zoo thiab qhov tsis zoo

Nyob rau hauv ntau qhov kev ua vaj tse, cov tsoos ua haujlwm zoo xws li naphthalene series ntau dua thiab tsis tuaj yeem ua tau raws li kev xav tau ntawm engineering vim muaj kev txwv ntawm kev ua haujlwm. Ib tiam tshiab ntawm cov dej-txo admixtures uas tau nyiam ntau yam nyob hauv tsev thiab txawv teb chaws, polycarboxylate-raws li kev ua haujlwm siab dej-txo cov khoom siv, vim tias lawv tau tsim cov qauv zoo molecular raws li cov txheej txheem ntawm kev ua ntawm cov cement dispersed, lawv yog hyperdispersed thiab tuaj yeem tiv thaiv kev poob qis. Nws tsis ua kom pom tseeb retardation, nthuav tawm cov nyhuv plasticizing siab ntawm qhov tsawg npaum li cas, zoo fluidity tuav, qib loj ntawm kev ywj pheej rau cement kom hloov mus rau cov qauv molecular dav, ntau cov txheej txheem synthesis, thiab chav zoo rau kev ua haujlwm siab, uas yog qhov zoo ntxiv rau pob zeb pob zeb. Cov nyhuv yog qhov zoo tshaj plaws, nws tuaj yeem txo qis qis ntawm cov pob zeb, cov ntsiab lus ntawm cov khoom tsis zoo yog qhov tsawg heev thiab lwm yam kev ua tau zoo, nws endows cov pob zeb nrog kev tsim kho zoo heev, kev txhim kho lub zog zoo, zoo heev durability, polycarboxylate high-performance dej reducer muaj kev ua tau zoo. Cov kev ua tau zoo ntawm kev ua tau zoo thiab kev tiv thaiv ib puag ncig ua tau raws li cov kev xav tau ntawm niaj hnub pob zeb engineering. Yog li ntawd, polycarboxylate-based superplasticizers maj mam dhau los ua cov khoom sib xyaw ua ke rau kev npaj cov pob zeb ua haujlwm siab. Raws li cov lus ceeb toom, kev siv polycarboxylate admixtures hauv Nyiv tau suav txog ntau dua 80 feem pua ​​​​ntawm tag nrho cov khoom siv ua haujlwm siab, thiab North America thiab Europe kuj suav txog ntau dua 50 feem pua. Hauv kuv lub tebchaws, polycarboxylate superplasticizers tau ua tiav tsuas yog hauv Peb Gorges Dam, Sutong Choj, Tianwan Nuclear Power Plant, Beijing-Shanghai high-speed railway thiab lwm yam kev txuag dej loj hauv tebchaws, choj, nuclear fais fab, thiab kev tsheb ciav hlau, thiab tau ua tiav cov txiaj ntsig zoo kawg li.

Khoom zoo

1. Zoo sib xws 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, cov dej txo qis thiab me me shrinkage.

3. Ua kom zoo heev thaum ntxov thiab lig zog 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 paug, tsis muaj formaldehyde, thiab ua raws li ISO14000 tus qauv thoob ntiaj teb rau kev tswj hwm kev tiv thaiv ib puag ncig. Nws yog ib yam khoom ntsuab thiab ib puag ncig tus phooj ywg.

6. Siv polycarboxylate dej reducer, ntau slag lossis ya tshauv tuaj yeem siv los hloov cov cement, yog li txo cov nqi.

Cov lus qhia

Kev noj ntau npaum li cas: Raws li ib txwm muaj, thaum hloov mus rau 20 feem pua ​​​​cov ntsiab lus khoom, qhov ntau npaum li cas yog 0.5 mus rau 1.5 feem pua ​​​​ntawm qhov hnyav ntawm cov khoom siv cementitious, thiab qhov pom zoo noj yog 1.0 feem pua.
