Isikrini se-polyurethane siyisikrini esingagugi sokuchotshozwa nokuhlungwa kwe-iron ore, ukuhlukaniswa kwamalahle aluhlaza, igolide, izinto zokwakha, kanye nokuhlolwa kwesihlabathi namatshe amatshe kwamaphrojekthi kagesi wamanzi kanye namandla enuzi. Sesivele siqonda izimboni ezithile lapho kusetshenziswa khona izikrini ze-polyurethane, kodwa kungenzeka singazi ukuthi yini okufanele siyinake lapho sigcina izikrini ze-polyurethane, ngakho ake sibheke ukuthi izikrini ze-polyurethane kufanele zigcinwe kanjani ndawonye!
Ukugcinwa kwezinto zokwakha kanye nensimbi yamapuleti esivikelo se-polyurethane kufanele kubekwe ngokwezigaba ezahlukene zensimbi, izinombolo zesithando, izinhlobo kanye nemininingwane, ubude kanye nezinkomba zobuchwepheshe ezahlukene. Izinto ezibuyisiwe kufanele futhi zibekwe ngezinto ezahlukene ukuze kube lula ukusetshenziswa. Insimbi kufanele ingangeni umswakama, ingangeni i-asidi-alkali futhi ingagqwali. Insimbi egqwalile kufanele ibekwe ngokwehlukana, isuswe ukugqwala ngesikhathi, futhi isetshenziswe ngokushesha okukhulu. Ukugcinwa kwezinto zokwakha zezikrini ze-polyurethane, kanye nokugcinwa kwesihlabathi kanye namatshe ayigugu, kufanele kubekwe futhi kugcinwe endaweni yokusetshenziswa kwephrojekthi noma eduze kwesiteshi sokuxuba ngokwecebo lokwakha, kanye nenani lemininingwane kufanele liboniswe epuletini lokubeka. Umhlabathi kufanele ube olinganayo futhi uqine, kanti isihlabathi kanye namatshe ayigugu kufanele kubekwe phezulu kwesikwele ukuze kuvinjelwe ukuthi indle kanye ne-resin yoketshezi kungacwiliswa enqwabeni yamatshe ayigugu. Amatshe anombala noma amatshe amhlophe ngokuvamile athunyelwa ezikhwameni ezilukiwe. Uma epakishwe ngobuningi, kufanele asetshenziswe ngemva kokuhlanza.
