Kev sib piv ntawm Polycarboxylate Superplasticizer thiab cov superplasticizer

TusPolycarboxylate Superplasticizer siab-ua tau dej reduceryog feem ntau npaj los ntawm copolymerization ntawm cov kev ua tau zoo hauv qab, tswj cov kev ua kom poob siab, thiab tsis muaj kev phom sij rau lub chaw thiab qhov tsis zoo ntawm cov cement. Lub polycarboxylate superplasticizer siab-ua tau dej recamerhyde condensehyde condensate smf reducers.

Txawm nyob ntawm qhov tsawg tsawg, nws tuaj yeem ua tshuaj khib thiab qhob qhob muaj cov viscosity siab, thiab tseem muaj kev ua tau zoo ntawm cov dej ntws tsawg. Nws muaj qhov sib txawv zoo dua nrog cov xis mas thiab yog cov khoom siv tsis tau rau lub zog siab thiab ua kom zoo.

Polycarboxylate SuperPasticizer muaj ntau cov dej ntws tawm qhob admixtureYog cov neeg siv hluav taws xob thib peb-ua tau zoo rau dej tsim kho tom qab calcium lignosulfonate thiab naphthalene dej reducers. Piv nrog cov dej tsoos dej ib txwm, nws tsuas yog muaj cov txiaj ntsig zoo hauv qab no:

Lub polycarboxylate superplasticizer siab-ua tau dej reducer tuaj yeem ua tiav cov dej txo qis ntawm 25-40%.

Lub zog loj zuj zus kev loj hlob, tshwj xeeb yog cov siab dua thaum ntxov lub zog kev loj hlob tus nqi.

Slumping zoo heev ua tau, uas tuaj yeem ua kom muaj kev poob qis dhau ntawm kev poob qis rau lub sijhawm rau pob zeb.

Cov qhob ua qhob muaj cov zoo nkauj heev, yog ib qho yooj yim rau ncuav thiab kev cog lus, thiab yog qhov haum rau kev ua kom tus kheej thiab kev sib txuas ua ke.

Cov dej txo qis, kev ceev nrias cia siab thiab ua haujlwm ntawm cov dej ua haujlwm ntawm cov dej ua haujlwm ntawm cov dej sib txuas, thiab ntom ntawm cov saw hlau.

Nws muaj qhov ua tau zoo thiab cov yees siv ROURIVE rau cov khoom ntshiab, Portland silicates, Fortland sixas thiab ntau yam admixtures thaum siv los ua pob zeb.

Nws tuaj yeem txhim kho lub ntim ruaj khov ntawm pob zeb ua, txo qis dua ntawm cov dej sib tw ntawm 20%

Tsis-toxic, tsis-corrosive, thiab pub dawb ntawm formaldehyde thiab lwm yam kev ua phem.

Kev ua haujlwm siabPolycarboxylate Superplasticizer Dej Reduceryog synthesized raws cov ntsiab cai ntawm qauv qauv molecular, siv DLVo tus qauv qauv muab kev xav thiab tus spatial steric cuam tshuam cov tswv yim ua lub hauv paus. Nws yog tsim los ntawm kev tsim cov sib txawv sib txawv cov pab pawg nquag mus rau cov saw tseem loj los ntawm polymerization. Cov saw hlau tseem ceeb ntawm poly-carboxylic acid high acid cov roj reducer molecule ua kom ruaj khov rau cov khoom siv hydration thiab txhim kho nws cov yas khaws cia. Sab saw ncig ib puag ncig lub Maas hais rau txhua sab, muab ntau dua ob qho tib si spatial steric hind cond cond condrop thiab electrostatic repulsion cuam tshuam. Qhov no sib txawv kiag li los ntawm lub tshuab ntawm cov dej tsoos dej uas disperse cementation los ntawm electrostatic repulsion. Yog li ntawd, nws tau muaj peev xwm ua tau zoo dua thiab txo dej-txo cov nyhuv, thaum kawg ua tiav qhov kev ua tau zoo ntawm cug thiab qhob cov khoom.

Tus pODYCARGEXYDRATE Superplasticizer dej txo tus neeg sawv cevYog npaj los ntawm kev ywj pheej radical daws polymerization, nrog cov chloride tsawg cov ntsiab lus. Tsuas yog ib qho me me ntawm alkali tau siv rau kev neutralization, thiab alkali cov ntsiab lus tsawg heev. Cov ntsiab lus Alkali thiab Chloride Ion cov ntsiab lus yog qhov ruaj khov. Txawm li cas los xij, cov alkali cov ntsiab lus ntawm naphthalene-based superplasticizer snf dej tus neeg sawv cev yog cuam tshuam los ntawm cov sulfoning, thiab muaj qhov sib txawv tseem ceeb ntawm cov txheej txheem ntau lawm.

Nws yog qhov paub zoo tias Alkali yog ib qho ntawm cov ntsiab lus tseem ceeb uas ua rau cov alkali-sib sau ua ke hauv pob zeb. Thiab rooj plaub uas qhov kev puas tsuaj cuam tshuam vim alkali-aggrate kev tiv thaiv yog ntau yam ob qho tib si hauv nruab domestically thiab thoob ntiaj teb. Lub alkali hauv cov qhob tsuas yog los ntawm cov khoom siv raw xws li MAAs, ya tshauv, thiab cov dej reducers. Kev tswj hwm ntawm Alkali cov ntsiab lus tseem ceeb heev thoob ntiaj teb. Hauv South Africa, tag nrho cov lus Alkali ntawm cov qhob yog txwv tsis pub tshaj 2.5kg / m3, thiab hauv Tebchaws Asmeskas, nws tau txwv tsis pub tshaj 3.3kg / m3. Raws li ib qho ntawm ob qho ntawm cov pob zeb ua kom muaj zog, cov ntsiab lus alkali ntawm cov dej reducers, tshwj xeeb tshaj yog cov ntsiab lus alkali cuam tshuam.

Tam sim no, ntau dua 90% ntawm cov dej reducers hauv Suav teb yognaphthalene dej reducersCov. Vim tias cov txheej txheem dej ntau lawm ntawm cov dej ntws tawm siv cov khoom siv roj ntsha thiab cov neeg ua haujlwm nyob ib puag ncig 10%, thiab cov tshuaj chlium iyd Thaum lub sij hawm polycarboxylate-based dej reducers yog qhov kev ua tau zoo ntawm dej, tsuas yog cov ntsiab lus alkali uas xav tau, thiab lawv yeej tsis muaj chloride ions. Cov ntsiab lus Alkali qis thiab tsis muaj chloride ions hauv rolycarboxylate-basy cov cheebtsam zoo rau kev npaj cov khoom loj ua kom zoo.

Hauv kev xaus,Polycarboxylate SuperPasticizer muaj ntau txo cov neeg sawv cevTsis tsuas yog txhim kho kev ua haujlwm ua haujlwm ntawm cov pob zeb ua tau tab sis kuj txhim kho kom zoo rau thaum ntxov thiab tom qab lub zog. Lawv tseem tsis tau muaj qhov tseem ceeb qhuas Insixtures hauv kev tsim kho niaj hnub no. Los ntawm kev ua kom zoo rau cov dej-xiss piv, txhim kho cov tshuaj tiv thaiv sab hauv, thiab txhim kho cov khoom siv sab hauv, polycarbox tau txais kev lees paub ntawm kev txhim kho ntawm qhob zog.

Ntawm cov khoom siv ntau yam, Shanxi Jiankai Zoo Tshuaj Kho Mob CompanyPolycarboxylate SuperPasticizer ntau cov dej ntws ntau, nrog nws cov kev ua tau zoo, muaj zog ruaj khov, thiab dav dav siv nyob rau hauv ntau cov txheej txheem sib txawv ntawm "kev txhim kho" kev ua kom ua tau zoo ".
