Zida zowotchera zinthu ndi chiyani

Tanthauzo la bioplastics: ngati mapulasitiki apangidwa ndi moyo, amatanthauzidwa kuti bioplastics, biodegradable, kapena onse awiri. Bio base amatanthauza kuti chinthucho (gawo) chimachokera ku zotsalira zazomera (chomera). Bioplastics imachokera ku chimanga, nzimbe kapena mapadi. Kusintha kwa bioplastics kumadalira kapangidwe kake ka mankhwala. Mwachitsanzo, 100% ya bio based, bioplastics sikuti imatha kusinthika.
Mapulasitiki omwe amatha kuwonongeka ndi mapulasitiki omwe amatha kuwonongeka chifukwa cha zinthu zamoyo, makamaka tizilombo ting'onoting'ono, m'madzi, mpweya woipa, ndi zotsalira zazomera.
Ngakhale kuti mawu akuti "bioplastic" ndi "pulasitiki yowonongeka" ndi ofanana, sizofanana. Si ma bioplastics onse omwe amatha kuwonongeka.
Biodegradation ndi njira yamagetsi yomwe tizilombo topezeka m'chilengedwe timasinthira zinthu kukhala zinthu zachilengedwe monga madzi, kaboni dayokisaidi ndi kompositi (popanda zowonjezera zowonjezera). Njira yochotsera kuchepa kwamadalira zimatengera momwe chilengedwe chikuyandikira (mwachitsanzo malo kapena kutentha), zofunikira ndi kagwiritsidwe kake.
Gulu la bioplastics


Gulu la bioplastics

Kukula kwa bioplastics lero
Ma polima obwezeretsanso amatha kugawidwa polima wowuma, polylactic acid (PLA) PHB polyhydroxyalkanoates (PHA) ma polima a cellulose.

Kutulutsa kwapadziko lonse kwa bioplastics kudzakhala matani 2.11 miliyoni mu 2019 ndi matani 2.43 miliyoni mu 2024, omwe akuyembekezeka kuwonjezeka pang'ono. Poyerekeza ndi kuchuluka kwapadziko lonse lapansi kopitilira 359 miliyoni pachaka / tani yamapulasitiki, imangokhala gawo lochepa. Mapulasitiki ofananawo (olimba komanso osinthasintha) amalamulira kuchuluka kwa ma bioplastics padziko lonse lapansi, opitilira theka (53%) mumsika wonse wa bioplastics chaka chatha.

Lingaliro la ma polima opangidwa ndi bio ndikubwezeretsa mafuta zakale ndi zinthu zowonjezeredwa komanso zachilengedwe (shuga muzomera), mwa kuyankhula kwina, kuti apange ma polima kuchokera kuzinthu zachilengedwe zomwe zitha kupangidwanso, ndikuwononga mwachangu ma CD ndikubwerera ku chilengedwe.

Zipangizo Zosintha Zambiri (Wuhu Radar Plastic Company Limited) zopanga ndi
Tikutenga PLA ndi PBAT ngati zida zathu zazikuluzazinthu zomwe titha kuzisintha
1, kumangirira kwa PLA, Filimu Yotambasula ya PLA, Kanema wonyamula wa PLA;
2, matumba a PLA (matumba agalu osakanikirana, matumba otayika), omwe ndi PLA + PBAT;
3, PLA udzu, zosungunuka zosweka PLA kumwa Mphasa.
Zogulitsa zathu zonse ndizosavuta kuononga 100%, yomwe ndi EN13432, ASTM D6400, BPI, FDA, yovomerezeka.
