Kukhudzidwa ndi dziko lapansi "Kuletsa Pulasitiki” ndi “Pulasitiki Ban"Malamulo, madera ena a dziko lapansi ayamba kuyika ziletso zazikulu za pulasitiki ndipo ndondomeko zoletsa pulasitiki zapakhomo zakhazikitsidwa pang'onopang'ono.Kufunika kwa mapulasitiki owonongeka kwathunthu kukupitilira kukula.PLA kwathunthu degradable pulasitiki ali ubwino wapadera poyerekeza ndi mapulasitiki ena degradable, ndipo pang'onopang'ono kukhala otchuka.

Kodi PLA ndi chiyani?

PLA polylactic acid, wotchedwanso polylactide, amatanthauza poliyesitala polima akamagwira polymerizing lactic asidi monga chuma chachikulu.Nthawi zambiri amapangidwa kuchokera ku wowuma woperekedwa ndi zomera zongowonjezwdwa (monga chimanga, chinangwa, ndi zina zotero).Ndi mtundu watsopano wa zinthu zowonjezedwanso zowola.

Chifukwa chiyani PLA zinthu 100% biodegradable?

PLA ndi zongowonjezwdwa zomera gwero, amene ali wabwino biodegradability ndipo akhoza kuonongeka kotheratu ndi tizilombo m'chilengedwe pambuyo ntchito.
Polylactic asidi ndi aliphatic hydroxy asidi polima, amene ndi zinthu zovuta mu galasi boma kutentha firiji, ndipo n'kukhala mpweya woipa, CH4 ndi madzi pansi kuwonongeka kwa tizilombo.Ndi liniya wathunthu zinthu biodegradable.

Ubwino wogwiritsa ntchito zinthu za PLA ndi zotani?

PLA tableware akhoza 100% decomposed mu carbon dioxide ndi madzi m'chilengedwe, kuthetsa vuto la kuipitsa woyera kuchokera muzu, kuteteza chilengedwe ndi kukwaniritsa chitukuko zisathe.

Pakadali pano, mabokosi anthawi zonse omwe amatha kutaya masana monga mabokosi otengeramo, mabokosi odyera, ndi mabokosi azakudya zam'masitolo akuluakulu amakhala opangidwa ndi zinthu zopangidwa ndi mafuta, ndipo kupanga kwake kumakhala ndi zowonjezera zambiri, zomwe zingayambitse khansa mthupi la munthu.Kusankha zinthu za PLA ndizabwino pa thanzi lanu.

Mkhalidwe wofulumira wa chilengedwe ndi ndondomeko: Malinga ndi ziwerengero zosakwanira, mpweya woipa wa carbon dioxide padziko lonse uyenera kukwera kufika pa 60 ° C mu 2030. Ichi ndi deta yowopsya.Bungwe la World Environmental Protection Organization likulimbikitsanso mwamphamvu mamembala ake kuti azisamalira chilengedwe.Chifukwa chake, ndichinthu chosapeŵeka chosintha mapulasitiki otayidwa ndi polylactic acid yotha kugwiritsidwanso ntchito pa biodegradable dinnerware.

PLA ili ndi kuyanjana kwabwino, kuwonongeka, makina amakina ndi zinthu zakuthupi.Ndiwoyenera kupangira njira zosiyanasiyana zopangira monga kuwomba ndi thermoplastic.Ndi yosavuta pokonza ndi ambiri ntchito.Fakitale yathu pakali pano imapanga Mabanja, monga tableware, mbale, udzu, zotengera, makapu, nkhomaliro mabokosi ndi zina zotero.
