Txhawm rau thov covTxau Polyurethane Ua Npuas Ncaujkom raug, peb yuav tsum siv sijhawm ntawm cov lej hauv tus account, xws li los ntawmatmospheric muaj rau ntau hom ntawm substrate thiab lawv qhov kub thiab dej cov ntsiab lus.
Cov chaw yuav tsum huv, qhuav thiab dawb ntawm hmoov av thiab rojTxhawm rau kom covzoo adhesion ntawm polyurethane ua npuas ncauj rau lub substrate; Yog hais tias lub substrate yog xim hlau, cov chaw yuav tsum yog tsis muaj xeb. Txhawm rau kom ntseeg tau zoo adhesion rau metallic substrates, nws raug nquahu kom siv lub primer uas haum. TusPom zoo yam tsawg kawg nkausntawm substrate thaum txau yog 5ºC.
TusTxheej Thicknessyog zoo kawg nkaus tswj tau thiab tuaj yeem hloov kho los ntawm kev hloov kho qhov nrawm thiab / lossis sib xyaw chamber ntawm rab phom. Nws yuav tsum raug sau tseg tias qis dua ntawm cov khaubncaws ntawm cov khaubncaws sab nraud povtseg thov kom ua tiav cov tuab tuab, yuav ua tiav cov khoom siv hluav taws xob ntau dua, ua tiav cov khoom siv thermal zoo dua. Thaum ua ntawv thov cov tuab loj heev, tus neeg thov yuav tsum thov cov khaubncaws sab nraud pov tseg kom tiv thaiv kom tsis txhob muaj ib txheej tshuaj tsuag Cov ntaub ntawv ntawm qhov siab tshaj plaws tuab ib txheej yog nyob rau hauv tdds (ntawv txheej txheem cov ntaub ntawv) rau cov khoom ntawd.
UV Kev Tiv Thaiv
Txau Polyurethane Ua Npuas Ncaujthov nyob rau hauv situMuaj tus cwj pwm zoo tau tiv thaiv cov neeg sawv cev atmospheric (dej, hnyav dua, cua,. Nws tsuas yogtawm tsam los ntawm kev sib kis mus ntevRau ultraviolet hluav taws xob, muaj, piv txwv li, hauv tshav ncaj qha.
Qhov kev tawm tsam no ua rau lubKev puas tsuaj ntawm polyurethane nto, uas ua rau muaj lub ntsej muag muaj plua plav rau saum npoo ntawm npaus. Qhov kev tawm tsam no ua rau muaj kev txo qis ntawm tus nqi ntawm 1 lossis 2 millimeters ib xyoos, nyob ntawm qhov sib xyaw ua ke ntawm cov tawv nqaij ntawm cov npuas dej, ib txheej ntawm kev kub siab polyurethane.
Kom zam dhau qhov kev txiav txim no,Daim ntawv thov sab nrauv yuav tsum tau coatednrog cov ntaub ntawv tshwj xeeb xws liPolyurethane Elastomers, Polyurethanes, Ximlossis lwm yam txheej txheem tshwj xeeb rau kev siv sab nrauv. Cov kev tiv thaiv no, zoo li lwm yam khoom siv, yuav tsum tau saib xyuas lawv txoj kev txuag thiab kev saib xyuas. Nyob rau hauv cov ntaub ntawv ntawm ib nrab ua npuass, tsau tshuaj yuav tsum tau nqa tawm los ntawm txoj kev txhuam los yog dej ntawm cov txheej txheem tshiab ntawm cov txheej txheem tshiab polyurethane ua yeeb yam thiab kev tiv thaiv sab nraud.
Kev tiv thaiv tiv thaiv kev tawg los ntawm kev nthuav dav
Nyob rau hauv polyurethane ua npuas ncauj uas yog ncaj qha rau kev nthuav tawm pob qij txha, cov kab nrib pleb yuav tshwm sim vim kev txav ntawm lub substrate los ntawmKev nthuav dav lossis kev cog lusCov. Cov nyhuv no tshwj xeeb tshaj yog nyob rau hauvdecks lossis terracesQhov twg tawg tuaj yeem tsoo cov dej tsis muaj dej. Nws yog yooj yim zam yog tias, thaum lub sijhawm ntawm daim ntawv thov, muaj kev ceev faj los ntawm kev kho cov sib koom ua ke.
Txawm hais tias muaj polyurethane ua npuas ncauj tau lees paub qee qhov kev ntxhov siab uas tsim los ntawm kev nthuav dav dav dav dav, txij li 2 cm, tsis tuaj yeem nqus tau los ntawm cov npaus. Txoj hauv kev uas cov kev txhawj xeeb no tuaj yeem nqus tau yog faib rau lawv, txo lawv cov teebmeem, los ntawm kev txhim kho ibElastic cais membrane, piv txwv li, ua cov roj hmab hluavtaws nrog ib qhov dav ntawm 30 cm, thiab thov polyurethane nyob rau sab saum toj ntawm nws.
