Izikrini ze-polyurethane ezivamile zifaka phakathi izikrini zemayini ye-polyurethane kanye nezikrini zokuphelelwa amanzi emzimbeni ze-polyurethane. Amapuleti ezikrini ze-polyurethane asetshenziswa ekubumbeni insimbi (i-iron ore, i-limestone, i-fluorite, i-cooling blast furnace slag, i-coke nezinye izinto zokusetshenziswa), izinsimbi ezingezona i-ferrous, amalahle, amakhemikhali, izinto zokwakha kanye nobunjiniyela bamandla kagesi, ukwelashwa kwemfucuza e-abrasive, i-quarry kanye nezinye izimboni. Ukumba, ukuhlola, ukuhlela kanye nezinye izimboni.
Ukusebenza okuyinhloko kanye nezici zepuleti lesivingo se-polyurethane yilezi:
1. Ukumelana okuhle nokuklwebheka, ukumelana kwayo nokuklwebheka kuphindwe kathathu kuya kahlanu kunokwamapuleti esisefo sensimbi kanye nokuphindwe kahlanu kunokwamapuleti esisefo senjoloba avamile.
2. Umsebenzi wokulungisa mncane, isikrini se-polyurethane akulula ukusonakalisa, futhi impilo yesevisi inde, ngakho-ke kunganciphisa kakhulu inani lokulungisa kanye nokulahlekelwa kokulungisa.
3. Izindleko eziphelele ziphansi. Nakuba isikrini se-polyurethane sobukhulu obufanayo (indawo) siphakeme kanye kunesikrini sensimbi engagqwali (cishe izikhathi ezi-2), isikhathi sokuphila kwesikrini se-polyurethane siphindwe kathathu kuya kahlanu kunesikrini sensimbi engagqwali, kanye nenani lokugcinwa nokufakwa esikhundleni. Ngakho-ke izindleko eziphelele aziphezulu, futhi zisebenza kahle kakhulu ngokwezomnotho.
4. Ukumelana okuhle nomswakama, ingasebenza ngaphansi kwesimo samanzi njenge-medium, futhi ngaphansi kwesimo samanzi, uwoyela kanye nezinye izinto, i-friction coefficient phakathi kwe-polyurethane nezinto ezisetshenziswayo iyancipha, okusiza kakhulu ekungeneni kwesikrini, kuthuthukisa ukusebenza kahle kokuhlola, futhi kungagwema izinhlayiya ezimanzi. Ngesikhathi esifanayo, ngenxa ye-friction coefficient encishisiwe, ukuguguleka kuyancipha futhi impilo yesevisi iyanda.
5. Imelana nokugqwala futhi ayishi.
6. Ngenxa yokwakheka okunengqondo kwezimbobo zesihlungo kanye nenqubo eyingqayizivele yokukhiqiza ipuleti lesihlungo, izinhlayiya zobukhulu obukhulu ngeke zivale izimbobo zesihlungo.
7. Ukusebenza kahle kokumunca ukudlidliza, ikhono eliqinile lokunciphisa umsindo, kunganciphisa umsindo, futhi kwenze izinto zesikrini zingaphuki kalula ngesikhathi senqubo yokudlidliza.
8. Ngenxa yezici zokudlidliza kwesibili kwe-polyurethane, isikrini se-polyurethane sinomphumela wokuzihlanza, ngakho-ke ukusebenza kahle kokuhlola kuphezulu.
9. Ukonga amandla nokunciphisa ukusetshenziswa. I-polyurethane inomncane amandla adonsela phansi futhi ilula kakhulu kunezikrini zensimbi ezinobukhulu obufanayo, ngaleyo ndlela kunciphisa umthwalo womshini wesikrini, konga ukusetshenziswa kwamandla futhi kwandise impilo yomshini wesikrini.
