Qhov sib txawv ntawm Naphthalene-raws li Superplasticizer Thiab Lwm yam Superplasticizers

Naphthalene-raws li high-efficiency dej reducers yog feem ntau nyob rau hauv tus cwj pwm nyob, yog li dab tsi yog qhov txawv ntawm naphthalene-raws li high-efficiency water-reducers thiab lwm yam dej-reducers? Tom ntej no, tus editor yuav muab peb cov lus qhia ntxaws:
Naphthalene-based high-efficiency dej-txo cov neeg ua haujlwm muaj cov dej txo qis dua li lwm cov dej-txo cov neeg ua haujlwm. Raws li GB8076, cov dej-txo tus nqi ntawm naphthalene-raws li high-efficiency dej-txo cov neeg sawv cev yog ntau dua los yog sib npaug rau 14 feem pua, thaum lwm yam dej-txo cov neeg ua hauj yog ntau dua los yog sib npaug rau 8 feem pua. Naphthalene-raws li high-efficiency dej reducers tsis tsuas yog muaj super-dispersive zog, tab sis kuj yuav inhibit qhov poob ntawm cov pob zeb, uas yog lub hom phiaj ntawm kev tshawb fawb thiab kev loj hlob ntawm cov dej reducers hauv tsev thiab txawv teb chaws. Naphthalene-based high-efficiency superplasticizers muaj qhov hloov tau zoo rau cov cement sib txawv, thiab feem ntau yuav pom cov viscosity tsawg thiab slump tuav cov khoom ntawm cov dej-rau-binder ratios, yog li lawv tau siv dav hauv Tebchaws Europe thiab Nyiv.
Naphthalene series high-efficiency dej reducer muaj cov yam ntxwv ntawm kev siv tsawg, dej txo tus nqi, me me poob qis, zoo ntim ruaj khov, tsis muaj corrosion rau steel tuav, thiab lwm yam., tsawg npaum li cas thiab dej txo tus nqi. Cov dej-txo tus neeg sawv cev niam cawv nrog cov ntsiab lus ntawm 20 feem pua ​​thiab ntau npaum li cas ntawm 1.0 feem pua ​​(tus nqi ntawm cov khoom siv gelling) tuaj yeem ua tiav qhov txo cov dej ntawm 26-30 feem pua, uas muaj tus nqi siab ua haujlwm.
