Chosankha chanu chachikulu ndi chiyani?biobased chikopa-3

Chikopa chopangidwa kapena chonyezimira sichichita nkhanza komanso ndichokhazikika pachimake.Chikopa chopanga chimachita bwino potengera kukhazikika kuposa chikopa cha nyama, koma chimapangidwabe ndi pulasitiki ndipo chimakhala chovulaza.

Pali mitundu itatu ya zikopa zopanga kapena zabodza:

PU chikopa (polyurethane),
PVC (polyvinyl kolorayidi)
zotengera zamoyo.
Mtengo wamsika wa chikopa chopangidwa ndi 30 biliyoni mu 2020 ndipo ukuyembekezeka kufika 40 biliyoni pofika 2027. PU idawerengera gawo la 55% mu 2019. chofewa kuposa PVC, komanso chopepuka kuposa chikopa chenicheni.Ikhoza kutsukidwa mouma komanso imakhalabe yosakhudzidwa ndi kuwala kwa dzuwa.PU ndi njira yabwinoko kuposa PVC chifukwa sichitulutsa ma dioxin pomwe bio-based ndi yokhazikika kuposa zonse.

Zikopa za bio-based zimapangidwa ndi polyester polyol ndipo zimakhala ndi 70% mpaka 75% zongowonjezedwanso.Ili ndi malo ofewa komanso okana kukana kuposa PU ndi PVC.Titha kuyembekezera kukula kwakukulu kwazinthu zachikopa za Bio-based mu nthawi yolosera.

Makampani ambiri padziko lonse lapansi amayang'ana kwambiri pakupanga zinthu zatsopano zomwe zili ndi mapulasitiki ochepa komanso mbewu zambiri.
Zikopa zochokera ku bio zimapangidwa kuchokera ku zosakaniza za polyurethane ndi zomera (zomera za organic) ndipo sizikhala ndi mpweya.Kodi mudamvapo za chikopa cha cactus kapena chinanazi?Ndi organic komanso yowonongeka pang'ono, ndipo ikuwonekanso yodabwitsa!Opanga ena akuyesera kupewa pulasitiki ndikugwiritsa ntchito viscose yopangidwa kuchokera ku khungwa la bulugamu.Zimakhala bwino.Makampani ena amapanga kolajeni kapena chikopa chopangidwa kuchokera ku mizu ya bowa.Mizu imeneyi imamera pazinyalala zambiri za organic ndipo njirayi imatembenuza zinyalala kukhala zinthu ngati zikopa.Kampani ina imatiuza kuti tsogolo limapangidwa ndi zomera, osati mapulasitiki, ndipo likulonjeza kupanga zinthu zosintha.

Tiyeni tithandizire kutukuka kwa msika wachikopa wa bio!
