Cov nyhuv ntawm cov dej ua haujlwm txo tau li cas?
Jan 15, 2025
Dej reducer yog ib tug admixture siv nyob rau hauv cov pob zeb ua kom txo cov dej sib xyaw thaum tswj cov pob zeb tawg. Feem ntau cov dej txo yog anionic surfactants. Thaum ntxiv rau cov pob zeb sib tov, nws disperses cov Maas hais tawm, txhim kho cov dej ua haujlwm, thiab txhim kho cov dej ntws ntawm cov pob zeb sib xyaw; Lossis nws tuaj yeem txo cov xis mas siv, yog li txuag cov cement.
02content hom dej reducers
Los ntawm pom:Dej reducers tuaj yeem raug cais ua kua thiab hmoov hom. Yuav cov kua feem ntau muaj cov khoom tawv tawv ntawm 10%, 20%, feem ntau hu ua niam cawv), thiab 50%, thaum cov hmoov uas feem ntau muaj cov ntsiab lus ntawm 98%.
Los ntawm dej txo thiab ua kom muaj peev xwm ua tau:
- Cov dej ntws ib txwm(tseem hu ua cov yas): cov no txo cov dej ntws los ntawm tsis muaj tsawg tshaj li 8%. Lignosulfonate yog tus sawv cev piv txwv.
- Cov dej ntws tsawg(Kuj tseem hu ua SuperPlasticizers): Cov no txo cov ntsiab lus dej los ntawm tsis muaj tsawg tshaj li 14%, suav nrog hom xws li Naphhalene-raws li, Melamine raws li, aminol-sulfonate-based, thiab aliphaatic series.
- Cov Dej Reducers High-Kev Ua Haujlwm: Cov no txo cov ntsiab lus dej los ntawm tsis pub tsawg tshaj 25%, nrog cov dej polycarboxylate-based dej reducers yog qhov feem ntau. Cov no tseem raug cais tawm thaum ntxov-lub zog, qauv, lossis cov hom retarding.
Los ntawm kev sib xyaw:Lignosulfonate, Polycyclic armomatic salitts, dej-soluble resin sulfonates, amaphatic high-asficient dej reducers, polycarboxylate cov dej reducers siab, thiab lwm yam.
Los ntawm kev siv tshuaj lom neeg:
- Lignosulfonate-based dej reducers
- Naphthalene-raws li cov dej muaj peev xwm ua tau zoo
- Melamine-raws li cov dej ntws ua haujlwm loj
- Aminosulfonate-raws li cov dej muaj txiaj ntsig zoo hauv cov dej
- Cov roj ntsha roj ua npuas dej-raws li cov dej tsis muaj roj
- Polycarboxylate-raws li cov dej muaj txiaj ntsig zoo
03Content Functions ntawm Dej Reducers
- Yog tias tsis muaj kev hloov pauv ntawm lwm cov ntaub ntawv (tshwj tsis yog cov cement) lossis lub zog ntawm cov pob zeb ua, dej reducers tuaj yeem txo tus nqi ntawm cov xis.
- Yog tsis muaj kev hloov pauv sib faib ntawm lwm cov ntaub ntawv (tshwj tsis yog cov dej) lossis cov swb ntawm cov pob zeb ua kom muaj zog txhim kho lub zog lub zog.
- Yog tias tsis hloov pauv cov ntaub ntawv ntawm lwm cov ntaub ntawv, cov dej ntws tuaj yeem txhim kho kev siv pob zeb ua kom zoo, yog li kev txhim kho kev tsim kho kev tsim kho thiab kev txhim kho kev siv hluav taws xob.
- Kev siv cov dej ntws hauv cov dej siab ua haujlwm hauv cov pob zeb tuaj yeem muab ob npaug rau nws lub neej, ua tau zoo txuas lub tsev lub neej ib txwm muaj.
- Dej Redrinkers txo qis qis ntawm cov pob zeb ua thaum muaj cov kab nrib pleb, kev tiv thaiv cov tub rog, ua kom nws muaj txiaj ntsig zoo, ua rau nws muaj txiaj ntsig zoo rau lub caij ntuj no.
