Dab tsi yog kev ua haujlwm thiab kev faib tawm ntawm cov pob zeb ua dej txo tus neeg sawv cev?
Dej reducer yog qhov tseem ceeb tshaj plaws ntawm cov khoom sib xyaw ua ke. Nws yog ib qho admixture uas tuaj yeem txo cov dej siv ntawm cov pob zeb thaum tswj cov dej ntws ntawm cov pob zeb. Dej reducer yog ib qho kev ntsuas tseem ceeb rau kev npaj cov pob zeb ua haujlwm siab. ib. Qhov sib ntxiv ntawm cov dej-txo tus neeg sawv cev ua kom cov dej ntws ntawm cov pob zeb ua kom zoo dua qub thiab txhim kho kev ua haujlwm tau zoo (thaum tswj xyuas tib tus nqi ntawm cov cement thiab dej-cement piv); vim qhov txo qis ntawm cov dej-cement piv, nws txhim kho lub zog thiab durability ntawm pob zeb, thiab lwm yam kev ua tau zoo (thaum tuav tib lub fluidity); los yog ob leeg.
Raws li tus qauv GB8076, kuv lub teb chaws faib cov dej sib xyaw ua ke rau hauv cov dej ua haujlwm siab (sawv cev los ntawm polycarboxylate cov dej ua haujlwm siab), cov dej ua haujlwm siab (xws li naphthalene series, melamine series, sulfamate series), aliphatic system, thiab lwm yam) thiab cov dej reducer (sawv cev los ntawm lignosulfonate) peb hom. Xyoo 2007, tag nrho cov txiaj ntsig ntawm ntau yam dej txo cov neeg ua haujlwm hauv kuv lub teb chaws yog kwv yees li 2.8454 lab tons, ntawm 175,100 tons yog cov dej txo cov neeg ua haujlwm zoo tib yam, suav txog 6.2 feem pua; 2.256 lab tons yog cov dej ua tau zoo txo cov neeg ua haujlwm, suav txog 79.3 feem pua; Cov dej ua tau zoo txo cov neeg ua haujlwm yog 414,300 tons, suav txog 14.6 feem pua. Txhua tus dej reducer siv cov khoom sib txawv thiab cov txheej txheem synthesis, thiab nws cov qauv molecular thiab cov yam ntxwv ua haujlwm kuj txawv.
