Automotive lim khoom
Rau cov khoom siv lim tsheb, cov kws tshawb fawb thaum ntxov tau siv cov ntaub ntub dej uas tsis yog-woven, tab sis lawv qhov kev pom zoo tag nrho yog qhov tsawg. Cov qauv mesh peb-dimensional endows koob punched nonwoven cov ntaub ntawv uas muaj porosity siab (txog 70% ~ 80%), siab muaj peev xwm, thiab siab pom tseeb, ua rau lawv yog ib qho tseem ceeb raw khoom rau automotive filtration cov ntaub ntawv. LAWRENCE et al. [10] txhim kho qhov pom kev ua tau zoo ntawm rab koob punched nonwoven fabrics los ntawm kev txo qhov nruab nrab pore loj thiab particle permeability ntawm qhov chaw los ntawm txheej txheej thiab dov txheej txheem. Yog li ntawd, kev siv cov tshuab laminating tuaj yeem txhim kho qhov pom kev zoo ntawm rab koob punched nonwoven cov ntaub ntawv.
Auto Sab hauv Khoom
CHEN et al. coated ib txheej ntawm thermoplastic polyurethane ntawm koob punched nonwoven ntaub los txhim kho cov khoom siv thiab nplaim taws ntawm TPU coated koob punched nonwoven khoom. Sun Hui et al. npaj ob hom koob punched ntaublaminated composite cov ntaub ntawv, siv thawj xim thiab dub polyethylene ua cov ntaub ntawv txheej, thiab tshuaj xyuas cov khoom micro thiab macro ntawm cov khoom sib xyaw. Cov txiaj ntsig kev tshawb fawb tau pom tias txheej txheej txheej tuaj yeem txhim kho cov crystallinity ntawm thawj xim polyethylene thiab txhawb cov khoom siv ntawm txheej txheej.
Automotive tiv thaiv cov ntaub ntawv
Spunbond nonwoven ntaubtau dhau los ua cov khoom siv zoo tshaj plaws rau cov khoom siv tiv thaiv tsheb vim nws muaj ntau yam zoo. Zhao Bo tau ua cov kev ntsuam xyuas ntawm cov khoom siv, ua pa, ya raws permeability, thiab qhov ruaj khov ntawm ob peb laminated spunbond nonwoven fabrics, thiab pom tias breathability thiab noo noo permeability ntawm laminated spunbond nonwoven cov ntaub ntawv poob. Yog li, cov txheej txheem muaj cov dej tsis zoo thiab cov roj resistant rau spunbond nonwoven cov ntaub ntawv, thiab muaj cov ntawv thov zoo heev hauv tsheb sab hauv, pom, thiab ntim.
Nrog rau kev nce ntawm cov nyiaj tau los ntawm ib tus neeg thiab qib kev noj qab haus huv, ntau tsev neeg muaj tsheb ntau dua, ua rau muaj kev tsis txaus ntawm tsev neeg tsheb nres tsheb hauv nroog. Ntau lub tsheb yuav tsum tau nres nyob rau hauv ib puag ncig sab nraum zoov, thiab qhov chaw ntawm lub tsheb yog yooj yim eroded los yog puas. Cov khaub ncaws hauv tsheb yog cov khoom siv tiv thaiv uas npog sab nrauv ntawm lub tsheb lub cev, muab kev tiv thaiv zoo rau lub tsheb. Tsheb khaub ncaws, tseem hu ua cov khoom siv hauv tsheb, yog cov cuab yeej tiv thaiv ua los ntawm cov ntaub pua chaw lossis lwm yam khoom siv tau yooj yim thiab hnav-tiv taus raws li qhov ntev ntawm lub tsheb. Nws tuaj yeem muab kev tiv thaiv zoo rau lub tsheb xim thiab lub qhov rais iav.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
