Biomass Da Ma'adinan Foda Cikakkun Layin Haɗaɗɗen Halitta

PLA shine gajartawar Ingilishi na polylactic acid mai yuwuwar halitta. Polylactic acid ne polymerized tare da lactic acid a matsayin babban albarkatun kasa. Tushen albarkatun ƙasa ya wadatar kuma ana iya sake haɓakawa, galibi masara, rogo, da sauransu. Tsarin samar da polylactic acid ba shi da gurɓatacce, kuma samfurin na iya zama biodegradable don gane wurare dabam dabam a cikin yanayi. Saboda haka, shi ne manufa kore polymer abu.

Polylactic acid yana da kyakkyawan kwanciyar hankali na thermal, sarrafa zafin jiki na 170 ~ 230 ℃, da juriya mai kyau. Ana iya sarrafa shi ta hanyoyi da yawa, kamar extrusion, kadi, mikewa biaxial da gyare-gyaren allura. Bugu da ƙari ga biodegradation, samfurori da aka yi da polylactic acid suna da kyakkyawar daidaituwa, mai sheki, nuna gaskiya, jin hannu da juriya na zafi, da kuma wasu juriya na ƙwayoyin cuta, rashin wuta da kuma UV. Saboda haka, ana amfani da su sosai azaman kayan tattarawa, zaruruwa da yadudduka waɗanda ba saƙa. A halin yanzu, an fi amfani da su a cikin tufafi (kamfai, kaya) da masana'antu (gini, noma, gandun daji da takarda) da kuma kula da lafiya.
