Lub luag haujlwm ntawm kev sib xyaw ua ke:

Lub luag haujlwm ntawm pob zeb additives txawv nrog rau hom pob zeb additives. Lub luag haujlwm dav dav yog txhawm rau txhim kho cov dej ntws ntawm cov pob zeb sib txuas thaum cov dej siv ib lub cubic meter ntawm cov pob zeb lossis cov cement noj tsis hloov; Thaum cov cement noj tseem tsis hloov lossis cov pob zeb tawg tseem tsis hloov pauv, kev siv dej tuaj yeem raug txo, thiab cov pob zeb ua kom zoo dua qub, thiab cov pob zeb ua kom zoo dua qub; thaum lub zog tsim thiab cov pob zeb ua pob zeb tsis hloov pauv, cov cement noj yuav txuag tau thiab tus nqi yuav raug txo, thiab lwm yam. Tus neeg saib xyuas lub zog thaum ntxov txhim kho lub zog thaum ntxov ntawm cov pob zeb thiab feem ntau yog siv rau kev kho thaum muaj xwm txheej ceev thiab lub caij ntuj no siv pob zeb; cov dej reducer muaj cov dej-txo thiab ntxiv zog thaum ua kom cov pob zeb sib xws tsis hloov; Cov huab cua entraining tus neeg sawv cev tsuas yog txo cov dej sib cais los ntawm cov npuas tsim thaum lub sij hawm sib xyaw ntawm cov pob zeb thiab txhim kho kev ua haujlwm ntawm pob zeb; tus retarder tuaj yeem ncua sijhawm teem sijhawm ntawm kev ua vaj tse, thiab muaj ob qho tib si retarding thiab dej-txo cov teebmeem. Nws yog tsuas yog siv rau cov pob zeb loj loj, pob zeb ua vaj tse nyob rau hauv cov huab cua kub, los yog pob zeb thauj mus ntev.

Kev tsom xam ntawm qhov cuam tshuam ntawm admixture dej reducer ntawm kev ua tau zoo:

Qhob admixture dej reducer yog tsim los ntawm surfactants. Qhov no surfactant belongs rau anionic surfactants. Nyob rau hauv qhov tseeb, pob zeb alkali dej tus neeg sawv cev tsis ua lub luag haujlwm tshuaj nrog cov cement. Nws cov nyhuv ntawm cov pob zeb yog qhov tseem ceeb hauv cov plasticization ntawm cov pob zeb tshiab. Plasticization yog ntub dej, adsorption, dispersion thiab lubrication nyhuv.

Lub adsorption, dispersion, lubrication thiab ntub cov teebmeem ntawm cov dej sib xyaw ua ke ua kom yooj yim sib xyaw cov pob zeb sib npaug nrog cov dej me me, kom cov haujlwm ua haujlwm ntawm cov pob zeb tshiab tau txhim kho. Qhov no yog cov nyhuv plasticization ntawm cov dej sib xyaw ua ke ntawm cov pob zeb tshiab.
