SM-F Cov Kws Tshaj Lij
SMF Superplasticizer yog sulphonated melamine formaldehyde raws li cov kws kho cov khoom superplasticizer. Nws ua kom pom cov cua tsis tshua muaj siab, zoo rau lub cev, tsis muaj xeb rau hlau thiab zoo heev yoog rau txhua yam ntawm cov cement lossis gypsum. Nws pom tseeb txhim kho lawv lub zog, fluidity thiab anti-permeability. Nws muaj kev ua haujlwm zoo, tuav dej thiab chav-kho kom yooj yim.
Daim ntawv thov:
1. Lub zog muaj zog gypsum, gypsum raws li tus kheej-theem pem teb, gypsum plaster, gypsum putty.
2. Maas raws li nws tus kheej-theem pem teb, hnav-ua hauj pem teb, kho tshuaj khib, tshwj xeeb siab muaj zog cug
3. Ua-Ua Tiav Ua tiav Ua tiav pob zeb / liab qab pob zeb, lub zog ua vaj tse thaum ntxov, ua tiav siab-qhob
