Cov txheej txheem ntau lawm rau daim ntawv- cov hnab yas sib xyaw feem ntau yog siv cov ntawv ua kom zoo nkauj dawb los yog daj kraft rau txheej txheej thiab cov ntaub qhwv yas rau txheej sab hauv. Nyob rau hauv cov xwm txheej ntawm qhov kub thiab txias siab, PP yas granules yog melted rau laminate daim ntawv kraft thiab woven ntaub ua ke; ib lub hnab sab hauv ntxiv tuaj yeem suav nrog.
Siv satellite luam ntawv thiab synchronous lamination technologies, cov txheej txheem tsim muaj cov hauv qab no:
1.Plastic ca yarns undergo biaxial stretching rau daim ntaub woven substrate.
2.Qhov saum npoo ntawm daim ntawv yog raug kho corona los txhim kho adhesion (ua tiav qib ntawm 38 mN / m lossis siab dua).
3.Ib ib qho -cov khoom, cov kuab tshuaj- cov nplaum dawb yog siv, nrog cov txheej txheem hnyav ntawm 1.8-3.0 g / m² rau qhov chaw du thiab ntau dua lossis sib npaug li 3 g / m² rau txheej sab hauv.
4.High -kub kub- xovxwm rollers (140–160 degree) yog siv los yaj cov PP granules, tso cai rau lawv nkag mus rau hauv cov ntawv fibers. Lub hnab- txheej txheem ua tau categorized ua ob hom: sewn- hnab hauv qab thiab tshav kub- hnab kaw; lub zog ntawm cov cua sov-cov seams kaw yuav tsum ua tiav qhov kev ntsuas tensile ntawm 30 N / 15 mm.
