Ua ntej no, cov ua npuas ncauj polyurethane ua cim xim:
Polyurethane npuas cov kaus poom ntawm kev siv kub ntawm +5 ~ +40 ℃, zoo tshaj plaws siv cov ntsuas kub +18 ~ +25 ℃. Qhov kub tsis tshua muaj teeb meem, nws pom zoo kom tias cov khoom nyob rau hauv +25 ~ +30 ℃ ntuj kub 30 feeb thiab tom qab ntawd siv, los xyuas kom meej nws cov kev ua tau zoo tshaj plaws. Qhov kub ntawm qhov tom qab kho yog -35 ° C rau + 80 ° C.
Qhov thib ob, kev siv cov roj ua npaws (polyurethane) Nco ntsoov:
1, polyurethane ua kua ua kua nplaum yog ib txoj yas ntub ua npuas, yuav tsum tau muab txau rau ntawm ntub ntub, ntau dua qhov av, qhov tseeb sai. Tus neeg ua noj ua haus yuav raug muab ntxuav nrog ib tus neeg tu lub tsev tu neeg, thiab cov phev ua si yuav siv los ntawm cov khoom siv cav (zom los yog txiav). Tom qab tua cov npuas dej yuav tau yellowed tom qab kis tau tus kab mob ultraviolet, nws pom zoo kom tias cov nplais ntawm npuas tom qab tua nrog lwm cov ntaub ntawv (cement mortar, xim, thiab lwm yam). Tom qab siv tshuaj tsuag siv tshuaj tsuag, ntxuav nws tam sim ntawd nrog ib tus tu neeg tshwj xeeb.
2, hloov lub tank, thawj lub tank rau co (tsawg kawg co 20 zaug), tshem cov khoob khoob khoob, muab cov khoom tshiab hloov tshiab, los tiv thaiv qhov phom kev sib txuas.
3, qhov phom sij tiv thaiv qhov ntswg thiab txhais tau muaj peev xwm tswj tau qhov kev npuas khiav ntawm qhov npuas. Thaum lub dav hlau nres, tig lub nris ntawm lub voj tshuab.
