Yuav ua li cas siv naphthalene raws li high-efficiency dej reducer
Dec 26, 2022
Naphthalene-raws li high-efficiency dej-txo tus neeg sawv cev yog tov nrog ib tug me me ntawm no tus neeg saib xyuas nyob rau hauv pob zeb, uas yuav ua rau kom cov densification ntawm pob zeb, txo cov dej siv, txuag cov cement noj, thiab txhim kho kev ua hauj lwm thiab durability ntawm cov pob zeb sib tov. Nws yog ib qho uas tsis yog huab cua-entraining high-efficiency dej reducer. Kev siv cov naphthalene-based high-efficiency dej reducer yog raws li hauv qab no:
1. Lub naphthalene-raws li high-efficiency dej reducer yog siv tom qab tau npaj rau hauv ib qho kev daws ntawm qhov xav tau concentration.
2. Cov hmoov tuaj yeem siv ncaj qha, lossis cov hmoov tuaj yeem ntxiv tom qab cov cement aggregate yog tag nrho wetted nrog 60 feem pua ntawm cov dej sib tov. Nws tuaj yeem muab faib ua cov txheej txheem sib xyaw ua ke thiab cov txheej txheem tom qab sib xyaw, thiab cov txiaj ntsig ntawm kev sib xyaw tom qab yog qhov zoo dua.
3. Naphthalene-based high-efficiency dej reducer cov khoom tuaj yeem sib xyaw nrog lwm cov khoom siv ua haujlwm los tsim cov khoom siv tshwj xeeb, tab sis lawv tsuas yog siv tau tom qab kuaj.
4. Nws yog siv rau cov pob zeb ua vaj tse nyob rau txhua hnub qhov kub thiab txias siab tshaj 0 degree, thiab yog tsim rau kev npaj loj fluidity pob zeb, high-strength pob zeb thiab steam-kho pob zeb.
5. Nws tuaj yeem siv rau kev txhawb nqa tus kheej thiab eutrophic pob zeb, cov pob zeb muaj zog thiab prestressed pob zeb npaj los ntawm ntau yam Portland cements. Thaum cov pob zeb sib xyaw nrog cov naphthalene-based high-efficiency dej txo tus neeg saib xyuas yog kho los ntawm chav, cov pob zeb yuav tsum muaj cov qauv tsim nyog. Lub zog tsuas tuaj yeem ua kom sov, thiab lub tshuab tua hluav taws xob yuav tsum tau txiav txim siab los ntawm kev sim.
Xav txog lub zog, kev ua haujlwm, kev ua haujlwm ntev, thiab tus nqi ntawm cov pob zeb, nws yog lub ntsiab lus tseem ceeb ntawm kev txhim kho yav tom ntej los tsim tshwj xeeb hloov kho naphthalene-based superplasticizers los ntawm cov txheej txheem hluavtaws lossis lub cev sib xyaw.
