Ndi kupititsa patsogolo chidziwitso cha chilengedwe, chifuniro cha anthu cha zinthu zowononga chilengedwe ndi katundu wawo chikuwonjezekanso. Compostable zakuthupi PLA ndi PLA compostable matumba ma CD pang'onopang'ono chimagwiritsidwa ntchito msika.
Polylactic acid, yomwe imadziwikanso kuti PLA (Polylactic Acid), ndi polima yomwe imapangidwa ndi polymerizing lactic acid monga zopangira zazikulu. Magwero a zopangira zake ndi zokwanira makamaka kuchokera ku chimanga, chinangwa, etc.
Ubwino wa PLA
1.Biodegradability: Pambuyo pa PLA itatayidwa, imatha kuwonongeka kwathunthu m'madzi ndi carbon dioxide pansi pazifukwa zinazake, ndikulowetsanso kayendedwe kachilengedwe, kupewa kuipitsidwa kwa nthawi yaitali kwa chilengedwe chifukwa cha mapulasitiki achikhalidwe.
2.Zongowonjezeranso: PLA imapangidwa ndi polymerized kuchokera ku lactic acid yotengedwa ku chimanga chowuma, nzimbe ndi mbewu zina, zomwe ndi zongowonjezedwanso, ndikuchepetsa kudalira mafuta amafuta.
3. Imakhala ndi mpweya wabwino, mpweya wa okosijeni ndi carbon dioxide permeability, umakhalanso ndi katundu wodzipatula fungo. Mavairasi ndi nkhungu amakonda kumamatira pamwamba pa mapulasitiki owonongeka, kotero pali nkhawa zokhudzana ndi chitetezo ndi ukhondo. Komabe, PLA ndiye pulasitiki yokhayo yomwe imatha kuwonongeka yokhala ndi anti-bacterial komanso anti-mold properties.
Njira yowonongeka ya PLA
1.Hydrolysis: Gulu la ester la unyolo waukulu limasweka, motero kuchepetsa kulemera kwa maselo.
2.Kuwonongeka kwa kutentha: chinthu chovuta kwambiri chomwe chimayambitsa kutuluka kwa zinthu zosiyanasiyana, monga mamolekyu opepuka ndi oligomers ozungulira ndi ozungulira okhala ndi zolemera zosiyana za maselo, komanso lactide.
3.Photodegradation: Ma radiation a ultraviolet angayambitse kuwonongeka. Izi ndizomwe zimapangitsa kuti PLA iwonetsere kuwala kwa dzuwa m'mapulasitiki, zotengera, ndi mafilimu.
Kugwiritsa ntchito kwa PLA m'munda wazolongedza
Zida za PLA zimagwiritsidwa ntchito m'magawo osiyanasiyana. Mu makampani ma CD, PLA filimu makamaka ntchito ma CD akunja chakudya, chakumwa ndi mankhwala m'malo mwa mwambo ma CD pulasitiki, pofuna kukwaniritsa cholinga cha kuteteza chilengedwe ndi zisathe.
PACK MIC imagwira ntchito bwino popanga matumba omwe amatha kubwezeredwanso ndi kompositi.
