Kodi zinthu zopangira manyowa ndi chiyani?

Kuwonongeka kocheperako ndikumachepetsa kukhathamira kwa zinthu, kutengera chilengedwe cha tizilombo tating'onoting'ono, nthawi yowonongera, mulingo ndi zomwe zimakhudza chilengedwe. European Union ili ndi tanthauzo la izi, lomwe limafotokozedwa kuti ndi "zinthu zosakwanira". Malinga ndi EN13432, zida zopanga manyowa zikuyenera kuwonetsa mawonekedwe a biodegradability, ndiko kuti, kuthekera kwa zinthu zopangira manyowa kuti zisinthe kukhala CO2 motsogozedwa ndi tizilombo tating'onoting'ono. Katunduyu adayesedwa ndi njira yoyeserera ya labotale: en14046 (yomwe idadziwikanso kuti iso14855: biodegradability under composting conditions). Pofuna kuwonetsa kuwonongeka kwa biodegradability, osachepera 90% yamiyeso ya biodegradation iyenera kufikira pasanathe miyezi 6.


EU ikupereka malamulo pazinthu zotsika mtengo zotsika mtengo

Kugawikaku kumayesedwa pamayeso oyeserera kompositi (en14045), mwachitsanzo, kugawanika ndi kuwoneka kosawoneka bwino (kopanda kuwonongeka) pamapeto pake. Zitsanzo za zida zoyeserera zidapangidwa ndi zinyalala zachilengedwe kwa miyezi itatu. Kompositi yomaliza kenako imasulidwa kudzera mu sefa ya 2 mm. Unyinji wa zotsalira za zoyeserera ndi kukula> 2mm zidzakhala zosakwana 10% ya misa yoyambayo.


Ndondomeko yazinthu zopanga manyowa

Panalibe zoyipa zilizonse pantchito yopanga manyowa, yomwe idatsimikiziridwa ndi kuyesa kwa mayeso oyendetsa ndege. Kuchuluka kwazitsulo zolemera (zochepera pazomwe zapatsidwa) ndipo sizikhala ndi zotsatirapo zomanga kompositi yomaliza (mwachitsanzo, kuchepetsa mphamvu za agronomic komanso kupezeka kwa zovuta zakuthambo pakukula kwazomera). Mayeso okula kwamasamba (oecd208 osinthidwa) ndi kusanthula kwina kwachilengedwe kudagwiritsidwa ntchito popanga manyowa pomwe kuwonongeka kwa zoyeserera kunachitika.

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 kupanga komanso zosazengereza 100%, zomwe ndi EN13432, ASTM D6400, BPI, FDA, zovomerezeka.
