Polycarboxylate superplasticizer admixture
Dec 12, 2023
Hauv kev lag luam admixture, xws li polycarboxylate superplasticizer, yog "formula" qhov tseem ceeb ntawm kev sib tw?
Nrog rau txoj kev loj hlob sai ntawm lub teb chaws kev lag luam thiab kev siv tshuab, kev ua haujlwm zoo ib puag ncig, ruaj khov thiab ua tau zoo thib peb tiam polycarboxylate superplasticizer tau dhau los ua "loj" hauv kev tsim kho kev lag luam. Nyob rau hauv txoj kev loj hlob ntawm polycarboxylate superplasticizer, polycarboxylate superplasticizer defoamer muaj txoj haujlwm tseem ceeb, lub luag haujlwm tseem ceeb yog tshem tawm thiab tswj cov npuas dej uas tsim los ntawm superplasticizer hauv kev tsim thiab siv cov txheej txheem, thiab txhim kho kev ua haujlwm ntawm superplasticizer.
Polycarboxylate superplasticizer yog siv dav hauv cov tsev niaj hnub, yog li qhov yuav tsum tau ua rau nws tau siab dua thiab siab dua, yog li nws yuav tsum tau ntxiv ntau yam tshuaj ntxiv los txhim kho kev ua haujlwm, thiab polycarboxylate superplasticizer defoamer yog ib qho tseem ceeb additives. Vim hais tias cov polycarboxylate alkali jellyfish cawv muaj ntau cov surfactants, thiab nws tus kheej cov ntsiab lus ntawm huab cua kuj loj, yog hais tias nyob rau hauv ntau lawm, high-speed stirring yuav tsim ib tug loj npaum li cas ntawm npuas; thaum nws tau siv ncaj qha rau hauv pob zeb, nws tseem yuav tsim cov npuas, uas cuam tshuam ncaj qha rau cov khoom zoo, ua rau cov ntsiab lus ntawm cov pob zeb ua kom siab dhau, cuam tshuam rau lub zog ntawm lub tsev, yog li nws yuav tsum tau ntxiv me me. ntawm defoamer kom tshem tawm cov teeb meem npuas hauv cov pob zeb. Lub defoamer ntawm polycarboxylate superplasticizer tshem tawm cov npuas loj tshaj hauv cov pob zeb, ua rau cov pob zeb zoo nkauj dua, txo cov ntsiab lus ntawm cov cua hauv polycarboxylate superplasticizer, txhim kho lub pore qauv thiab compactness ntawm cov pob zeb, thiab ua rau cov pob zeb sib xyaw ua ke ntau dua thiab kaj.
Kev siv cov polycarboxylate superplasticizer defoamer1, tuaj yeem ncaj qha ntxiv rau lub foaming kua superplasticizer, nplawm kom ntseeg tau tias nws tsis sib xws; 2, los yog siv cov twj tso kua mis ncaj qha mus rau qhov xav tau tshem tawm cov npuas dej superplasticizer, qhov pom zoo ntxiv tus nqi yog hais txog {{ 2}}.
