Mapulogalamu
➢ Kusinthika kwabwino kwa mitundu yonse ya simenti, kukonza magwiridwe antchito a konkriti, omwe amagwiritsidwa ntchito kwambiri m'misewu, njanji, milatho, tunnel, malo opangira magetsi, DAMS, nyumba zazitali ndi ntchito zina.
1. Kusakaniza mlingo pa 0.5% -1.0%, 0.75% kusakaniza mlingo analangiza.
2. Konzani mayankho ngati pakufunika.
3. Kugwiritsa ntchito mwachindunji ufa wa ufa kumaloledwa, mwinamwake kuwonjezera kwa wothandizira kumatsatiridwa ndi madzi moisturization (chiŵerengero cha madzi-simenti: 60%).
Zochita Zazikulu
➢ SNF-A imatha kupereka matope mwachangu, kuthamanga kwambiri kwa liquifying, kutsika kwa mpweya.
➢ SNF-A imagwirizana bwino ndi mitundu yosiyanasiyana ya simenti kapena gypsum binders, zowonjezera zina monga de-foaming agent, thickener, retarder, expansive agent, accelerator etc.
➢ SNF-A ndiyoyenera kupaka matailosi, zodzipangira zokha, konkriti yowoneka bwino komanso zowumitsa zamitundu.
Magwiridwe Azinthu
➢ SNF ikhoza kugwiritsidwa ntchito ngati chonyowetsa matope osakaniza kuti mupeze ntchito yabwino.
☑ Kusunga ndi kutumiza
Iyenera kusungidwa ndi kuperekedwa pansi pa mikhalidwe yowuma ndi yoyera mu mawonekedwe ake oyambirira a phukusi ndi kutali ndi kutentha. Pambuyo pake phukusi latsegulidwa kuti lipangidwe, kusindikizanso mwamphamvu kuyenera kutengedwa kuti zisalowemo chinyezi.
☑ Alumali moyo
Alumali moyo miyezi 10. Gwiritsani ntchito mwamsanga pansi pa kutentha kwakukulu ndi chinyezi, kuti musawonjezere mwayi wa caking.
☑ Chitetezo cha katundu
Naphthalene based superplasticizer SNF-A si ya zinthu zoopsa.Zambiri zokhudzana ndi chitetezo zaperekedwa mu Material Safety Data Sheet.
