Cov khoom tseem ceeb ntawm polyurethane slotted screen panels yog siab -molecular- hnyav polyurethane (PU), ib tug polymer synthesized los ntawm cov tshuaj tiv thaiv ntawm polyols thiab isocyanates. Polyurethane muaj cov elasticity zoo heev, ua kom tsis zoo, thiab tiv thaiv corrosion, ua rau cov tshuaj ntsuam xyuas kom ruaj khov ua haujlwm tau zoo - tsis yooj yim tawg lossis deforming -txawm tias nyob rau hauv cov xwm txheej siab - zaus vibration thiab cov khoom cuam tshuam. Lub hardness thiab elasticity ntawm polyurethane tuaj yeem ua raws li cov yam ntxwv tshwj xeeb ntawm cov khoom raug tshuaj xyuas, yog li ua tau raws li qhov yuav tsum tau muaj rau kev puas tsuaj thiab kev tshuaj ntsuam xyuas qhov tseeb pom nyob rau hauv ntau qhov chaw ua haujlwm.
Txhawm rau txhim kho qhov kev tiv thaiv kev puas tsuaj, lub zog muaj zog, thiab kev pabcuam lub neej ntawm cov tshuaj ntsuam vaj huam sib luag, polyurethane slotted cov ntxaij vab tshaus feem ntau suav nrog ib qho kev faib ua feem ntawm cov muab tub lim lossis cov khoom siv txhawb zog- xws li calcium carbonate, talc, iav fibers, lossis polymeric additives. Cov additives no ua rau cov khoom muaj zog thiab hnav tsis kam thaum tib lub sijhawm txhim kho cov yam ntxwv ntawm polyurethane, ua rau cov qauv slotted ruaj khov nyob rau hauv siab - zaus vibration thiab tsis tshua muaj kev deformation lossis tawg. Rau cov ntawv thov tshwj xeeb, siab - kub- tiv taus, tiv thaiv - zoo li qub, lossis corrosion- cov tshuaj ntxiv kuj tseem tuaj yeem muab tso ua ke kom ua tau raws li qhov tshwj xeeb kev tshuaj ntsuam xyuas ntawm cov kev lag luam tshwj xeeb. Tsis tas li ntawd, thaum lub sij hawm tsim cov txheej txheem ntawm polyurethane slotted cov ntxaij vab tshaus, catalysts thiab cov nqi tsim nyog ntawm foaming agents yog siv los tswj tus nqi ntawm cov tshuaj tiv thaiv polymerization thiab tswj cov khoom siv lub cev.
