Rov ua duaPET spunbond nonwoven ntaubyog cov txheej txheem tseem ceeb uas txhawb nqa kev ruaj khov thiab txo qhov cuam tshuam ib puag ncig. Raws li kev siv thev naus laus zis thiab kev tsim kho kom zoo dua qub, kev siv PET spunbond rov ua dua yuav tsum tau nthuav dav dua.Tuam Tshoj tus tsiaj spunbond nonwoven ntaubfeem ntau yog siv.
1. Sau thiab sorting:
Kev Sau: PET spunbond nonwoven npuag yog sau los ntawm ntau qhov chaw, suav nrog cov khoom pov tseg tom qab siv (piv txwv li, cov khaub ncaws siv, ntim khoom, thiab cov khoom siv pov tseg) thiab cov khoom siv pov tseg (xws li kev tsim cov khoom khib nyiab).
Kev Soj Ntsuam: Cov ntaub ntawv sau tau raug txheeb cais los ntawm PET spunbond los ntawm lwm hom textiles thiab plastics. Qhov no feem ntau ua manually los yog siv automated sorting systems.
2. Kev Kho Mob Ua Ntej:
Ntxuav: Cov ntaub qhwv PET spunbond yog ntxuav kom tshem tawm cov av, khib nyiab, thiab lwm yam kab mob. Qhov no yuav suav nrog kev ntxuav, ziab, thiab qee zaum kev kho tshuaj.
Shredding: Cov ntaub huv huv yog shredded rau hauv me me los pab txhawb rau theem tom ntej ntawm kev rov ua dua tshiab.
3. Reprocessing:
Melting: Lub shredded PET spunbond ntaub yog melted nyob rau hauv high kub. Qhov no rhuav tshem cov saw hlau polymer thiab hloov cov khoom siv rau hauv lub xeev ua kua.
Extrusion: PET molten yog ces extruded los ntawm ib tug tuag, uas shapes nws mus rau hauv filaments. Cov filaments no ces spun rau hauv cov fibers tshiab.
Nonwoven Tsim: Cov spun fibers tau nteg thiab sib koom ua ke los tsim cov ntaub ntawv tshiab. Qhov no tuaj yeem ua tiav siv ntau txoj hauv kev, xws li rab koob punching, thermal bonding, lossis tshuaj sib txuas.
4. Kev ua tiav:
Calendering: Cov ntaub tshiab uas tsis yog ntaub yog feem ntau calendered los txhim kho nws smoothness, lub zog, thiab tiav.
Dyeing thiab Printing: Cov ntaub tuaj yeem dyed lossis luam tawm los tsim cov xim sib txawv thiab cov qauv.
5. Kev siv:
Recycled PET spunbond nonwoven npuag tuaj yeem siv rau ntau yam kev siv, zoo ib yam li nkauj xwb PET spunbond, suav nrog:
Khaub ncaws thiab khaub ncaws
Geotextiles
Ntim
Industrial thiab technical applications
Cov ntsiab lus tseem ceeb los xav txog:
Zoo:Recycled PET spunbond ntaubtej zaum yuav muaj cov khoom sib txawv me ntsis piv rau cov khoom siv nkauj xwb, xws li lub zog tensile qis los yog qhov ua tiav tsis zoo. Txawm li cas los xij, kev nce qib hauv kev siv thev naus laus zis tau txhim kho qhov zoo ntawm PET spunbond rov ua dua tshiab.
Kev Xav Tau Kev Lag Luam: Qhov kev thov rau cov khoom siv rov ua dua tshiab PET spunbond npuag tau loj hlob raws li cov neeg siv khoom thiab cov lag luam nrhiav kev xaiv kom ruaj khov.
Environmental Benefits: Recycling PET spunbond fabric txo cov khib nyiab pov tseg, txuag cov peev txheej ntuj, thiab txo qis cov pa roj carbon monoxide.
Kev sib tw:
Kev Tiv Thaiv: Kev sib kis los ntawm lwm cov ntaub ntawv tuaj yeem cuam tshuam qhov zoo ntawm cov khoom siv rov ua dua tshiab ntawm PET spunbond.
Tus nqi: Recycling PET spunbond npuag tuaj yeem kim dua li siv cov khoom siv nkauj xwb.
Infrastructure: Ib qho chaw muaj zog rau kev sau, txheeb xyuas, thiab rov ua dua PET spunbond ntaub yog qhov tseem ceeb rau kev rov ua dua tshiab.
