Raws li lawv cov qauv tsim, polyurethane siab -frequency screen panels feem ntau muab faib ua ob pawg: ib qho thiab modular. Integral screen panels yog tsim los ntawm ib leeg, khoom ntawm polyurethane khoom; lawv feem ntau yog siv nyob rau hauv ib qho - lawj tshuaj ntsuam tshuab lossis me me - mus rau - nruab nrab - cov cuab yeej loj, uas yog lub ntsej muag tiaj tus, kev co tsis zoo, thiab yooj yim ntawm kev teeb tsa. Modular screen panels, conversely, yog assembled los ntawm ntau interlocking polyurethane modules. Cov no tsim nyog rau cov tshuab loj - ntsuas ntsuas lossis ntau- lub tshuab tshuaj ntsuam xyuas lub lawj, muab qhov hloov pauv hloov tus kheej raws li cov yam ntxwv ntawm cov khoom siv lossis qib hnav. Txoj hauv kev no tsis yog tsuas yog txo cov nqi txij nkawm thiab txuas ntxiv lub neej kev pabcuam tag nrho ntawm lub vijtsam tab sis kuj ua kom muaj kev tshuaj xyuas zoo ib yam.
Raws li cov duab aperture thiab cov khoom siv sib xws, polyurethane siab -frequency screen panels tuaj yeem muab faib ua round- qhov, square- qhov, thiab slotted (ntev- qhov) hom. Round- cov ntxaij vab tshaus qhov muaj qhov sib txawv apertures thiab yog qhov zoo tagnrho rau kev tshuaj xyuas cov hmoov zoo lossis cov khoom siv nrog qhov loj me me, muab kev tshuaj ntsuam xyuas siab. Square-cov ntxaij vab tshaus yog haum rau kev tshuaj ntsuam nruab nrab- mus rau- cov ntaub ntawv ntxhib, vim lawv txhim kho cov khoom nkag mus thiab txo qis aperture clogging. Cov ntxaij vab tshaus yog feem ntau ua haujlwm rau cov ntaub ntub dej, nplaum, lossis cov ntaub ntawv fiber ntau; lawv elongated aperture tsim pab txhawb cov khoom tawm, tiv thaiv kev tshuaj ntsuam clogging, thiab boosts kev ntsuam xyuas efficiency.
Polyurethane siab -frequency screen panels kuj tuaj yeem raug cais raws li lawv cov hardness thiab cov khoom tshwj xeeb. High-cov ntxaij vab tshaus hardness yog tsim los rau cov ntaub ntawv abrasive heev-xws li ores thiab aggregates- muab qhov tshwj xeeb hnav tsis kam thiab ua haujlwm ntev. Nruab nrab- cov ntxaij vab tshaus hardness yog tsim rau kev tshuaj xyuas cov khoom siv dav dav, xws li cov hmoov tshuaj thiab cov yas granules. Tsawg- cov ntxaij vab tshaus hardness yog qhov zoo tagnrho rau kev tshuaj ntsuam ntub dej, agglomerating, los yog cov ntaub ntawv friable, vim lawv pab txo cov khoom tawg thiab tiv thaiv aperture clogging. Tsis tas li ntawd, cov tshuaj ntsuam xyuas tshwj xeeb uas muaj cov khoom xws li siab -kub tsis kam, corrosion resistance, thiab anti{11}} muaj peev xwm zoo li qub muaj peev xwm ua tau raws li ntau hom kev tshuaj ntsuam xyuas ntawm ntau qhov chaw muaj kev lag luam, yog li ua kom muaj kev soj ntsuam zoo thiab cov khoom zoo.
