Urea tubing feem ntau yog ua los ntawm polypropylene. Polypropylene yog cov thermoplastic resin nrog qhov zoo xws li lub teeb yuag, siab zog, corrosion kuj, siab thiab kub tsis kam, halogen-dawb xwm, thiab recyclability. Qhov no ua rau polypropylene qhov kev xaiv zoo tshaj plaws rau urea tubing hauv SCR systems.
Hauv cov ntsiab lus, urea tubing ua lub luag haujlwm tseem ceeb hauv SCR systems, thiab kev xaiv ntawm nws cov khoom cuam tshuam rau tag nrho cov kev ua haujlwm ntawm lub cev. Tam sim no, polypropylene yog cov khoom siv tseem ceeb rau kev tsim urea tubing, thiab nws yuav txuas ntxiv siv dav hauv kev siv yav tom ntej.
