Yog, tab sis nrog qee yam mob.Non Woven Fabric BagsFeem ntau yog ua los ntawm cov khoom siv polypropylene. Cov resin yog yaj los ntawm cov txheej txheem spunbond los ua cov khoom tshiab. Yog li, cov ntaub ntawv keeb kwm tseem ceeb dua li cov txiaj ntsig kev xeem zaum kawg. Cov lus nug tseem ceeb yog qhov twg cov khoom siv rov ua dua tshiab los ntawm, ntau npaum li cas cov khoom siv rov ua dua tshiab siv rau hauv cov ntaub, thiab seb cov khoom siv rov ua dua tshiab puas tuaj yeem txheeb xyuas tau.
Post{0}}kev lag luam polypropylene pov tseg yooj yim dua rau kev siv. Nws yog huv si, ib chav kawm, zoo ib yam. Kev pov tseg pov tseg yog qhov nyuaj tom qab noj. Nws yuav tsum tau muab cais, ntxuav thiab ntxuav ua ntej nws tuaj yeem siv los ua cov ntaub zoo ib yam. Ntau lub hnab ntim khoom lag luam siv 30-100% raw khoom los ntawm RPP. Thaum cov kab extrusion tau tswj tau zoo, qhov hnyav, lub zog thiab kev luam ntawv zoo ntawm lub hnab tiav zoo ib yam li cov khoom qub.
Nov yog qhov hloov pauv thaum siv rov ua dua tshiab thiab yuav ua li cas kom zoo thiab ua raws li qhov chaw.
Yuav ua li cas Recycled Resin Ua Tsis yog -Woven Fabric
Piv nrog rau lwm txoj kev tsim khoom, cov txheej txheem spunbond ua rau nws yooj yim dua los siv cov khoom siv rov qab. Tsis yog- woven npuag yog tsim los ntawm molten polypropylene, uas tuaj yeem ua raw los yog rov ua dua tshiab, ntawm qhov kub ntawm 200 thiab 230℃. Cov khoom siv molten yog thawb dhau lub dav hlau los tsim cov filaments txuas ntxiv. Tom qab ntawd cov filaments yog dispersed mus rau hauv ib tug random web thiab sib koom ua ke kom sov rau daim ntawv. Vim hais tias cov polymer yog melted kiag li thiab re- tsim, cov ntaub tsis "nco" seb cov resin los ntawm cov khoom pov tseg los yog siv yogurt nruas. Qhov tseem ceeb yog qhov zoo ntawm cov khoom siv rov ua dua tshiab uas nkag mus rau hauv lub tshuab.
Muaj ob qhov chaw tseem ceeb ntawm Recycled PP:
Ncej -kev lag luam (PIR):Qhov no suav nrog kev tsim cov txiav, kawg - ntawm - lub neej rollers thiab tsis yog - woven zeb pov tseg. Qhov no feem ntau yog cov khoom siv huv tshaj plaws. Nws muaj tib qib polymer thiab feem ntau muaj cov kab mob me me lossis xim txawv. Feem ntau ntawm nws yog rov siv dua nyob rau hauv lossis ze rau tib lub Hoobkas.
