Kev tsom xam ntawm Sodium Naphthalene Sulfonate SNF
Jul 26, 2024
TZ-FDN yog ib qho kev sib xyaw ua ke uas muaj txiaj ntsig zoo nrog kev ua tau zoo, feem ntau yog tsim los ntawm Sodium Naphthalene Sulfonate (SNF). Cov khoom no muaj kev cuam tshuam zoo heev, txo cov dej ntsiab lus ntawm cov pob zeb, txhim kho fluidity thiab slump, thiab txhim kho kev ua haujlwm. Tsis tas li ntawd, nws tuaj yeem ua kom muaj zog thiab muaj zog thaum ntxov ntawm cov pob zeb, muab cov txiaj ntsig zoo rau kev siv ntau yam cement.
Cov yam ntxwv ua haujlwm
Kev nyab xeeb: Cov khoom yog non-toxic, non-flammable, thiab ruaj khov, tsis muaj corrosive nyhuv ntawm steel reinforcement.
Cov ntsiab lus cua: Cov ntsiab lus huab cua nyob ntawm 2.0-4.0%, muaj txiaj ntsig zoo rau kev tsim vaj tsev.
Kev sib xyaw: Tsawg sodium sulfate cov ntsiab lus (tsawg dua 5%), tiv thaiv kev tsis zoo.
Dej txo: Tus qauv hom kev ua tau zoo ntawm cov dej reducer tuaj yeem txo cov ntsiab lus dej los ntawm 14-25%, ua kom cov dej ntws ntawm cov dej sib tov nrog qhov poob ntawm 15-22cm. Hom retarding high-efficiency dej reducer tuaj yeem txuas ntxiv lub sijhawm teem ntawm pob zeb los ntawm 2-15 teev, txhim kho lub zog mus ntev, txo cov dej kub, thiab txo qhov kub ntawm qhov sib txawv.
Cov lus qhia siv
Pom zoo noj: Cov hmoov ntau npaum li cas feem ntau yog {{0}}.8-2.0% ntawm cov khoom siv khi, thaum cov kua ntau ntau yog 1.5-3.0% ntawm cov ntaub ntawv binder. Qhov ntau npaum li cas yuav tsum tau hloov kho raws li qhov yuav tsum tau ua thiab txheeb xyuas los ntawm kev sim.
Ntxiv Sijhawm: Nws yog feem ntau pom zoo kom ntxiv thaum lub sij hawm tom qab ntawm kev sib tov los yog ua ntej pouring rau kev pom zoo.
Cov nyhuv Optimization: Cov neeg siv tau qhia kom ua qhov kev sim ua ntej los txiav txim siab qhov zoo tshaj plaws thiab txoj kev ua ntej siv thawj zaug.
Performance Indicators
Ua raws li GB8076 "Concrete Admixtures" cov qauv rau cov dej ua haujlwm siab:
| Cov khoom kuaj | TZ-FDN Standard Type | TZ-FDN Retarding Type |
|---|---|---|
| Dej txo tus nqi /% | Ntau dua lossis sib npaug li 14 | Ntau dua lossis sib npaug li 14 |
| Teem sijhawm sib txawv / min | ||
| Kev teeb tsa thawj zaug | -90 ~ +120 | Ntau dua lossis sib npaug rau +90 |
| Kev teeb tsa zaum kawg | -90 ~ +120 | / |
| Compressive zog / MPa | ||

| 3d | Ntau dua lossis sib npaug li 130 | / |
| 7d | Ntau dua lossis sib npaug li 125 | Ntau dua lossis sib npaug li 125 |
| 28d | Ntau dua los yog sib npaug rau 120 | Ntau dua los yog sib npaug rau 120 |
Cov cheeb tsam thov
Loj Volume Concrete Siv: Haum rau qhov loj ntim pob zeb ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig, xws li kab, kab teeb, thiab daim ntawv slip-form.
Ntau qib pob zeb: tuaj yeem siv los npaj cov pob zeb ntawm qib C15-C50.
Tshwj xeeb pob zeb: Haum rau kev npaj shrinkage-txo cov qhob, thaum ntxov-lub zog high-efficiency dej-txo pob zeb, thiab nruam kev tsim vaj tse nyob rau hauv huab cua kub. Nws pab txo qis dej kub, txo qhov kub thiab txias kev ntxhov siab, thiab tiv thaiv thermal tawg, ua kom lub neej ntev thiab kav ntev ntawm cov qauv.
Ntim Thiab Cia
Cov khoom ua kua yuav tsum tau muab khaws cia rau hauv cov thawv ntim khoom raws li tus neeg siv xav tau, thiab cov khoom siv hmoov yuav tsum tau ntim raws li cov neeg siv khoom xav tau. Khaws rau hauv qhov chaw txias, qhuav, tsis txhob tshav ntuj ncaj qha. Lub neej txee yog ib xyoos.
