Recycled PVB (RPVB), yomwe imadziwikanso kuti Recycled Polyvinyl Butyral, ndi chikopa chopangidwa ndi kukonzanso magalasi opangira magalasi amagalimoto osiyidwa.Monga zinthu zapolymeric, chikopa cha PVB cha ogula chimagwiritsidwa ntchito kwambiri ndi mafakitale a upholstery, ma CD, ndi magalimoto.
Chifukwa chiyani PVB yobwezerezedwanso ndi chinthu chokhazikika?
1.Recycled PVB carbon footprint ndi nthawi 25 kuposa PVB namwali.Onjezani thanzi lazinthu zazinthu zathu.Madzi ochepa, palibe mankhwala oopsa, komanso malamulo oyendetsera zachilengedwe.
2.Polekanitsa, kuyeretsa, ndikusintha, PVB yobwezerezedwanso imatha kusinthidwa kukhala zida zomalizidwa.Kupyolera mukupanganso, mafilimu ofewa osiyanasiyana, ulusi wokutira, ndi zinthu zotulutsa thovu zimapangidwa.
3.Kugwiritsa ntchito nkhaniyi kumachepetsa carbon footprint ya precoat ndi 80% poyerekeza ndi latex chikhalidwe.Matailosi onse amtundu wa tuff carpet tsopano amapangidwa ndi precoat yake, kuchepetsa kukhudzidwa kwa chilengedwe.
4. PVB yobwezeretsedwanso imapangidwa pokonzanso magalasi opangira magalasi opangira magalimoto osiyidwa.Potero kusandutsa chinthu ichi chomwe chinali chosasinthika kukhala chapamwamba kwambiri.Izi zikutanthauza kuchepetsa zinyalala za magalasi, zomwe ndi zabwino ku chilengedwe chathu.Pa nthawi yomweyo kutembenukira kwa zinyalala gwero, kuti ndi zabwino kwa dziko lathu lapansi.
Chifukwa chiyani timasankha zobwezerezedwanso PVB zakuthupi?
1. Zida za PVB ndizosavomerezeka ndi Dothi komanso sizinganyowe, ndizosavuta kuyeretsa zikwama zathu.
2. Popeza PVB zakuthupi ndi zamphamvu kwambiri.Zopangidwa kuchokera ku PVB zobwezerezedwanso ndizamphamvu komanso zosokonekera.
3.Recycled PVB chikopa kapangidwe wapadera amapereka versatility ntchito lonse, ndipo ndi njira yabwino kwa PVC.
4. PVB yobwezerezedwanso ndi yochezeka komanso yopanda vuto kwa anthu pochepetsa kuchuluka kwa mpweya pomwe ikuwonjezera thanzi lazinthu.Simaphatikizapo mankhwala oopsa monga Dimethylformamide (DMF) ndi Dimethylfumarate (DMFu).
5. Zobwezerezedwanso PVB mulibe Palibe BPA, Palibe Plasticizers, Palibe Phthalates, ndi otetezeka.
6. Zobwezerezedwanso PVB ndi degradable, ndi eco-wochezeka zakuthupi.
7. Zinthu zopangidwa kuchokera ku PVB zobwezerezedwanso zimawoneka zapamwamba kwambiri, zowongoka, zokongola, zopanda madzi komanso zolimba.Anthu ambiri amakonda nkhaniyi.
8. Mtengo wa zobwezerezedwanso PVB si mkulu.Chifukwa chake ogula ambiri amatha kuvomereza mtengo wazinthu zopangidwa kuchokera ku PVB yobwezerezedwanso.
