BBCA polylactic acid sabbin kayayyaki

Polylactic acid (PLA) wani nau'in sabon abu ne wanda aka samar ta hanyar ƙarin polymerization na lactic acid daga sitaci ko fermentation na sukari. Ba ya amfani da man fetur a matsayin albarkatun kasa, kuma yana da halaye na kare muhalli, maras guba, antibacterial, mai kare harshen wuta, mai kyau biocompatibility da biodegradability. Shine sabon abu mafi alƙawari don girgiza matsayin gargajiya na robobi na tushen man fetur da zaruruwan sinadarai a nan gaba.

Polylactic acid da samfuransa suna da bargarar kaddarorin jiki a ƙarƙashin yanayin zafi na al'ada da yanayin zafi. Yana da kwata-kwata mai lalacewa, wanda za'a iya sake yin fa'ida. Bayan an jefar da shi, ana iya lalata shi zuwa carbon dioxide da ruwa. Bayan photosynthesis ta tsire-tsire, tsire-tsire na iya sake shanye shi kuma ya shiga cikin da'irar halitta ba tare da iyaka ba. Shi ne "kayan sake amfani da muhalli na karni na 21".

(1) hanyoyin da za a sabunta su: galibi daga masara, dankalin turawa da sauran amfanin gona na sitaci, da kuma bambaro, da sauransu;

(2) cikakken biodegradation: shi za a iya sha da metabolized ta jikin mutum; samfuran sun lalace gaba ɗaya zuwa CO2 da H2O a cikin ƙasa ko ruwan teku bayan an jefar da su a cikin sharar ƙasa a cikin shekara guda, suna fahimtar zagayowar carbon akan saman kuma yadda yakamata ya canza gurɓatar muhalli ta hanyar kayan tushen man fetur;

(3) Dangantakar jikin mutum da aminci: albarkatun kasa na lactic acid yana kunshe a cikin jikin mutum, PLA na iya zama metabolized da shayar da jikin mutum, PLA shine FDA bokan kayan dasa ɗan adam, wanda aka yi amfani da shi sosai a fagen likitanci shekaru da yawa;

(4) kyakkyawan tsari: ana iya sarrafa shi ta hanyoyi da yawa, kamar extrusion, kadi, zanen biaxial, gyare-gyaren allura;

(5) na halitta antibacterial da anti mite: kwayoyin cutar antibacterial da anti mite kudi na Candida albicans, Escherichia coli da Staphylococcus aureus ya kai fiye da 95%;

(6) jinkirin harshen wuta na halitta: lafiyayye da jinkirin harshen wuta, ƙarancin hayaki, babu hayaƙi baƙar fata da iskar gas mai guba;

(7) kyau kwarai mai sheki, nuna gaskiya, rike, UV juriya, danshi conductivity, babu danshi sake samun, da dai sauransu.

Ana iya yin polylactic acid zuwa polylactic acid fiber, kuma aikinsa yana kama da na auduga. Bugu da ƙari, polylactic acid yana da irin wannan aikin ga kayan aikin sinadarai na gaba ɗaya kamar polypropylene (PP), polyethylene (PE), polyester fibers (PET, PTT, PBT). Ana iya sarrafa shi ta hanyar gyare-gyaren allura, extrusion, spinning da sauran matakai don yin zaruruwa, fina-finai, zanen gado da faranti, a hankali maye gurbin Petrochemical zaruruwa da robobi na man fetur, Ana amfani da shi sosai a cikin tufafi, marufi, noma, gida, sassa na mota, bugu 3D, biomedicine da sauran filayen.
