Cov nplaum polyurethane muaj ntau cov ntawv thov ntau, thiab cov nplaum ntawm cov khoom sib txawv xav tau cov khoom lag luam sib txawv. Nws yog dav siv, thiab muaj teeb meem cia. Cov khoom no muaj qee qhov ua kom muaj kev kub ntxhov thiab kev phom sij. Yog li koj yuav khaws nws li cas?
1. Cov nplaum ua kua nplaum Polyurethane muaj cov nplaim hluav taws kub, yog li lawv yuav tsum ua kom deb ntawm hluav taws thiab khaws cia hauv qhov chaw qhuav;
2. Nws yuav tsum muab cia rau hauv qhov chaw tso cua thiab txias, thiab qhov chaw cia khoom txias yog 25 ℃;
3. Lub sijhawm cia ntawm polyurethane nplaum tsis ntau tshaj 12 lub hlis;
4. Khaws qhov cua thaum siv thiab tsis txhob kov cov tawv nqaij.
Qhov saum toj no plaub lub ntsiab lus yog qhov tseeb kev khaws cia ntawm polyurethane nplaum. Kev khaws cia kom zoo tuaj yeem nce nws siv sijhawm thiab txo cov khoom pov tseg tsis tsim nyog. Nws yog qhov tsim nyog yuav tsum tau them sai sai rau qhov teeb meem kub thiab ib puag ncig hauv nws txoj kev cia thiab siv. Tom qab siv cov kua nplaum, nws yuav tsum sib raug zoo sai li sai tau thiab ua tiav rau tib hnub. Txav deb ntawm kev ua qias tuaj thiab kev tiv thaiv huab cua noo, thiab tuaj yeem nres tsheb tsis pub dhau 3 hnub. Qhov kev cia khoom kom raug thiab kev siv nws tuaj yeem txhim kho kev ua haujlwm ntawm qee yam.
