Kev tsim cov polyurethane slotted screen panels pib nrog kev npaj ntawm raw cov ntaub ntawv, feem ntau muaj xws li polyols, isocyanates, thiab tsim nyog fillers thiab additives. Raws li qhov xav tau ntawm daim ntawv thov ntawm lub vijtsam thiab cov yam ntxwv ntawm cov khoom raug soj ntsuam, cov qauv raug hloov kho kom meej meej tswj cov polyurethane lub hardness, elasticity, thiab abrasion tsis kam. Rau qhov siab - hnav ib puag ncig, cov khoom siv ntxiv tuaj yeem ntxiv los txhim kho kev puas tsuaj; conversely, rau cov ntaub ntawv ntub dej los yog agglomerating, yooj yooj yim yuav tau nce los tiv thaiv lub qhov clogging. Cov ntaub ntawv raw tau raug hnyav hnyav thiab sib xyaw kom ntseeg tau tias cov tshuaj tiv thaiv tsis sib xws, yog li tsim cov polyurethane matrix nrog cov yam ntxwv ua haujlwm ruaj khov.
Cov khoom sib xyaw polyurethane npaj tau muab tso rau hauv ua ntej- tsim cov tshuaj ntsuam pwm rau casting thiab molding. Lub geometry ntawm lub slotted apertures yog precisely tswj los ntawm cov pwm, kom ntseeg tau qhov sib xws ntawm qhov dav, qhov sib nrug, thiab kev sib dhos. Rau qhov loj - nplai lossis ntau- cov ntxaij vab tshaus, ib qho segmented, modular casting txoj kev tuaj yeem ua haujlwm los pab txhawb kev sib dhos thiab hloov tom qab. Thaum lub sij hawm casting txheej txheem, ua tib zoo saib xyuas yog them rau qhov cua thiab tiv thaiv huab cua nkag kom tsis txhob tsim cov voids los yog tsis xws luag uas yuav cuam tshuam qhov kev tshuaj ntsuam xyuas qhov tseeb thiab lub zog tshuaj ntsuam. Tom qab molding, lub polyurethane tau ua tiav cov txheej txheem kho nyob rau hauv qhov kub thiab txias thiab lub sijhawm ua haujlwm kom ua tiav qhov xav tau cov khoom siv kho tshuab thiab kev puas tsuaj.
Tom qab ua tiav ntawm kev kho, cov ntxaij vab tshaus polyurethane slotted undergo demolding, trimming, thiab nto tiav kom tshem tawm cov burrs ntau dhau thiab xyuas kom meej lub tiaj, du nto. Tom qab ntawd, kev tshuaj xyuas nruj yog ua los xyuas qhov ntev, hardness, tensile lub zog, thiab aperture precision, kom ntseeg tau tias txhua qhov screen vaj huam sib luag raws li cov kev qhia tshwj xeeb. Qee cov khoom lag luam kuj tseem yuav raug kuaj ntxiv los ntsuas lawv cov kev puas tsuaj lossis kev tiv thaiv corrosion. Thaum pom zoo, cov ntxaij vab tshaus tau ntim raws li cov lus qhia tshwj xeeb los tiv thaiv kev puas tsuaj thaum caij tsheb npav; Cov khoom siv phau ntawv thiab cov lus pom zoo siv tau suav nrog los xyuas kom meej tias cov neeg siv khoom tuaj yeem ua tiav kev soj ntsuam zoo thaum lub sijhawm teeb tsa thiab ua haujlwm.
