Kodi mumadziwaPulani mbale, Pulani kapu kapu ya khofi? Polylactic acid (plu) ndi osiyana ndi poliopr okwera ma armoplastic poizoni chifukwa zimachokera ku zinthu zopangidwa mwaluso ngati chowuma cha chimanga kapena nzimbe. Zithunzi zambiri, mosiyana, zimachokera ku distillation ndi polymerization kwa malo osafunikira a petroleamu. Phukusi lomwe limachokera ku biomass (E.g. Pla) limadziwika kuti "bioplastics."

Pulani mbale, kapenaPulani kapu kapu ya khofi ndi 100% yovuta.Polylactic acid ndi biodegradgle ndipo ali ndi mawonekedwe ofanana ndi polypropylene (pp), polyethylene (pe), kapena polystyrene (PEL). Itha kupangidwa kuchokera ku zida zomwe zakhalapo kale (zomwe zakonzedwa ndipo poyambirira zimagwiritsidwa ntchito kwa opanga ma protanics). Izi zimapangitsa kuti zikhale zochulukirapo zokolola. Chifukwa chake, play ili ndi gawo lachiwiri lopanga bioplastic (lofala kwambiri lomwe limatchulidwa ngati wowuma wa thermoplastic).

Pali ntchito zambiri za polylactic acid. Zina mwazinthu zofala kwambiri zimaphatikizapo mafilimu apulasitiki, mabotolo, ndi zida zamagetsi zamankhwala (mwachitsanzo, zikhomo, zikhomo, ndodo zomwe zikuyembekezeka kukhala zosakwana miyezi 6-12). Pulo imakhazikika pansi pa kutentha ndipo pofika pofika poti mugwiritse ntchito ngati zokutira. Kuphatikiza apo, kufota komwe polylactic acif amalola kugwiritsa ntchito zina zosangalatsa mu 3d kusindikiza ("kukhala" Kutaya Pulata "). Kumbali inayo, kutentha kwake kosinthika kumapangitsa mitundu yambiri ya plaf (mwachitsanzo, makapu apulasitiki) osayenera kugwira madzi otentha.
