Lub phiaj xwm polyurea ntawm kuv txoj siv tau raug txau thaum Lub Kaum Hli, 2016. Nws nyob hauv Datong nroog, xeev Shanxi thiab tag nrho cov tshuaj tsuag thaj tsam yog 1800 square meters. Peb tau txau peb cov khoom Qtech-404 polyurea rau kuv txoj siv sia. Peb cov polyurea ntshiab txheej tau tiav zoo heev abrasion tsis kam, ruaj thiab tsos tshwm sim.
Cov txheej txheem kev tsim kho yog ua raws:
1. Ntxuav cov ntaub nyias nyias.
2. Sau qhov tawg nrog polyurea sib xyaw ua ke.
3. Primer daim ntawv thov.
4. Ua ntej peb yuav tsum thaiv qhov khoom tsis xav kom txau kom tsis txhob txau rau cov khoom sib kis ntawm nws qhov chaw. Tom qab ntawd peb tuaj yeem txau cov tshuaj ntshiab polyurea.
