Polycarboxylate superplasticizer yog ib hom tshiab ntawm cov dej-txo cov neeg ua haujlwm npaj los ntawm monomer multi-component water-based polymerization water reducer.Vim muaj cov qauv molecular tshwj xeeb, cov dej txo tus neeg sawv cev tuaj yeem paub qhov tawg ntawm cov cement hais los ntawm ob qho kev ua ntawm electrostatic repulsion thiab steric barrier, uas qhia tau zoo heev dispersibility thiab dispersion retention muaj peev xwm.Cov khoom no muaj qhov zoo ntawm cov khoom siv tsawg, cov dej txo qis, cov txiaj ntsig zoo, cov ntsiab lus tsis tshua muaj alkali, tsis muaj corrosion ntawm steel tuav thiab ib puag ncig tus phooj ywg.Qhov thib peb-tiam kev ua tau zoo ntawm cov dej-txo tus neeg saib xyuas tau tsim tom qab tus neeg saib xyuas dej txo qis yog tam sim no tus neeg saib xyuas dej txo qis tshaj plaws hauv ntiaj teb, nrog cov ntsiab lus thev naus laus zis siab tshaj plaws, qhov kev thov zoo tshaj plaws thiab kev ua tau zoo tshaj plaws.
Polycarboxylate superplasticizer muaj kev tuav pov hwm zoo dua nyob rau hauv cov xwm txheej ntawm kev hloov pauv zoo rau cov ntaub ntawv siv.
Kev poob qis ntawm pob zeb hauv 1.5h yog qhov me me, feem ntau tsis ntau tshaj 15%, uas yog qhov zoo heev rau kev thauj mus los ntev ntawm cov pob zeb.
Qhov sib xyaw ua ke npaj nrog polycarboxylate superplasticizer muaj peev xwm ua haujlwm tau zoo thiab muaj kev sib koom ua ke zoo.
Nws muaj qee yam huab cua lom zem, uas tuaj yeem ua rau cov ntsiab lus huab cua ntawm pob zeb ntau dua 2%.
Kev hloov pauv ntawm qhov sib xyaw ua ke muaj qee yam cuam tshuam rau huab cua lom zem khoom ntawm polycarboxylate superplasticizer, thiab qhov nce ntawm cov ntsiab lus ntawm huab cua tsis muaj kev cuam tshuam rau lub zog.
Nws muaj kev txhawb zog zoo rau cov pob zeb uas muaj zog, thiab lub zog loj hlob ruaj khov, feem ntau 7 hnub
Lub zog tuaj yeem ncav cuag li 100% ntawm tus tsim lub zog, thiab lub zog txuas ntxiv mus rau theem tom ntej.
Cov qauv molecular muaj ntau txoj kev ywj pheej, thiab muaj ntau yam tswj tsis tau nyob rau hauv cov khoom siv additive manufacturing technology.
Polycarboxylate superplasticizers nrog cov khoom tshwj xeeb thiab kev siv tuaj yeem npaj tau los ntawm kev kho cov qauv molecular, uas yooj yim kom tau raws li qhov xav tau ntawm ib puag ncig kev hloov pauv ntawm qhov chaw tsim kho.
Cov khoom lag luam yog ntsuab thiab ib puag ncig tus phooj ywg, thiab tsis muaj cov khoom xyaw uas tsim kev puas tsuaj rau ib puag ncig thiab cuam tshuam rau tib neeg kev noj qab haus huv.
Qhov zoo ntawm polycarboxylate superplasticizers yog pom tseeb rau txhua tus, tsis sib xws los ntawm lwm hom superplasticizers.Raws li ntev raws li peb saib cov teeb meem no los ntawm ib tug systematic thiab kev loj hlob foundations, ntxiv dag zog rau kev koom tes thiab kev koom tes ntawm producers thiab cov neeg siv ntawm superplasticizers, nrog rau cov cement manufacturers, muab tag nrho cov kev ua si rau qhov zoo ntawm polycarboxylate superplasticizers, thiab siv zog kov yeej lawv cov shortcomings, daim ntawv thov Kev cia siab ntawm polycarboxylate superplasticizer yuav dav dua.
