Cov ua haujlwm ntawm cov khoom siv polyurethane polyurethane yog tias A (isocyanate tivthaiv) thiab R (yam khoom xyaw hydrogen) yog ntsuas ntawm tus nruas mus rau lub ntsiab tshuab ntawm cov twj tso tawm, ntsuas, cov pa, rhaub, thiab tom qab ntawd xa mus rau phom phom. , txau tom qab phom rab phom tuaj. Metering conveyors thiab nws cov tshuab yog ob lub ntsiab lub tshuab cov khoom tsuag tsuag. Yog li, cov cuab yeej siv tshuaj tua kab (polyurea spray) yuav tsum muaj: ib qho khoom siv txawb, tsim cov khoom ntsuas, khoom sib xyaw xim, lub cev zoo atomization system thiab khoom siv yooj yim.
Polyurea spray txheej, polyurea tshuaj tsuag yuav tsum tau nqa tawm hauv 3 rau 168 xuab moos tom qab daim ntawv thov. Yog tias lub luv tshaj 168 xuab moos, tus qauv yuav tsum rov ua dua ib hnub ua ntej txau lub polyurea txheej, thiab tom qab ntawd ces siv cov txheej txheem polyurea. Qhuav poly tej huab cua yog siv los tshuab ntawm lub plua plav ntub dej ua ntej yuav siv cov tshuaj polyurethane.
Ua ntej yuav siv cov tshuaj polyurethane, lub cheeb tsam ib puag ncig yuav tsum raug xam tias yog. Cov yeeb yaj kiab yuav tsum siv los npog cov khoom puag ncig uas yuav muaj kab mob, thiaj li tiv thaiv thaj chaw ib puag ncig.
