Cov txheej txheem cua lim ntau lawm

Cov txheej txheem cua lim cov txheej txheem suav nrog cov kauj ruam tseem ceeb suav nrog kev tsim, xaiv cov khoom siv, kev ua haujlwm, kev sib dhos, thiab kev tshuaj xyuas zoo, nrog rau cov khoom siv lim dej yog qhov tseem ceeb. Cov khoom siv lim dej yuav tsum muaj kev pom zoo (piv txwv li, ntawv lossis iav fiber ntau nrog qhov pore loj ntawm 0.3-0.4μm). Tom qab ua ntej ua ntej los ntawm kev txiav thiab folding, nws yog tsim los ntawm kev sib txuas los yog stitching. Punching thiab ntug nias yog ua los txhim kho huab cua permeability (airflow kuj tsawg dua los yog sib npaug rau 50Pa) thiab durability. Thaum lub sij hawm sib dhos, lub foob yuav tsum tau ua kom ntseeg tau ntawm lub tsev thiab lub lim dej (tus nqi to<1%). Finally, after meeting standards for airflow resistance and filtration efficiency (≥99.5%), the filter is packaged and shipped. This process is widely used in the automotive and construction machinery sectors, effectively reducing engine wear and particulate matter emissions.
