Cov ntsiab lus tseem ceeb ntawm kev siv thev naus laus zis ntawm naphthalene series high-efficiency dej reducer
Dec 28, 2022
Naphthalene-raws li superplasticizer yog ib qho tshuaj uas tsis yog-cua-entraining superplasticizer, uas muaj zog heev dispersion nyhuv ntawm cov cement hais. Naphthalene-raws li high-efficiency dej reducers muaj ntau lawm ntim thiab ntau yam kev siv hauv kuv lub teb chaws, thiab tshwj xeeb tshaj yog tsim rau cov pob zeb ua haujlwm. Cia peb saib ntawm daim ntawv thov thiab cov ntsiab lus dej ntawm naphthalene-based superplasticizers:
1. Qhov tsim nyog npaum li cas ntawm naphthalene-raws li high-efficiency dej reducer yog: cua-entraining hom xws li methylnaphthalene-raws li, condensed-ring aromatic anthracene-raws li, thiab lwm yam. Tus nqi ntawm cov cement yog 0.{{8 }} 0 feem pua ; hom tsis-air-entraining xws li melamine resin-raws li , Qhov ntau npaum ntawm naphthalene-raws li superplasticizer tuaj yeem xaiv tau ntawm 0 3-5 feem pua , thiab qhov ntau npaum li cas yog 0.{{ 17}} 0 feem pua . Thaum nws yog siv nyob rau hauv prefabricated Cheebtsam uas yuav tsum tau chav curing txheej txheem, cov tshuaj yuav tsum tau txo kom tsim nyog.
2. Nws raug nquahu kom sib tov cov naphthalene-based high-efficiency dej reducer nyob rau hauv daim ntawv ntawm kev daws, tab sis cov dej hauv cov tshuaj yuav tsum tau txiav tawm ntawm tag nrho cov dej siv.
3. Txoj kev siv ntau dua thiab pom zoo yog ntxiv nrog rau cov dej sib tov.
4. Composite high-efficiency superplasticizers muaj cov khoom xyaw sib txawv thiab muaj ntau hom. Txawm hais tias nws tsim nyog los tsis yog yuav tsum tau kuaj thiab tshuaj xyuas ua ntej. High-efficiency superplasticizers kuj muaj teeb meem hloov mus rau cov cement vim qhov sib txawv ntawm cov cement hom, fineness, thiab mineral Cheebtsam, yog li lawv yuav tsum tau siv tom qab kuaj.
5. Naphthalene-based high-efficiency dej-txo cov neeg ua haujlwm, tshwj tsis yog sulfamic acid thiab graft copolymers, muaj qhov poob loj ntawm cov pob zeb, uas tuaj yeem poob 30-50 feem pua hauv 30 feeb, yog li yuav tsum tau saib xyuas thaum siv.
Naphthalene-based high-efficiency dej-txo tus neeg sawv cev muaj cov dej-txo tus nqi thiab zoo adaptability rau pob zeb, thiab yog dav siv nyob rau hauv kev tsim kho, mining, dej txuag, tsheb thauj mus los thiab lwm yam engineering kev tsim kho.
