Chifukwa cha kukulitsa chidziwitso cha chilengedwe, anthu akufuna zinthu zosawononga chilengedwe komanso zinthu zawo zomwe amagulitsa nazonso zikuwonjezeka. Zinthu zosungiramo manyowa monga matumba osungiramo manyowa a PLA ndi PLA zikugwiritsidwa ntchito kwambiri pamsika pang'onopang'ono.
Polylactic acid, yomwe imadziwikanso kuti PLA (Polylactic Acid), ndi polima yomwe imapezeka poyatsa lactic acid ngati chinthu chachikulu chopangira zinthu. Magwero a zinthuzo ndi okwanira makamaka kuchokera ku chimanga, chinangwa, ndi zina zotero. Njira yopangira PLA ndi yopanda kuipitsa, ndipo chinthucho chikhoza kuwola ndi kubwezeretsedwanso m'chilengedwe.
Ubwino wa PLA
1. Kuwonongeka kwa chilengedwe: PLA itatayidwa, imatha kuonongeka kwathunthu kukhala madzi ndi carbon dioxide pansi pa mikhalidwe inayake, ndikulowanso m'magazi achilengedwe, kupewa kuipitsa chilengedwe kwa nthawi yayitali komwe kumachitika chifukwa cha mapulasitiki achikhalidwe.
2. Zinthu zongowonjezedwanso: PLA imapangidwa makamaka kuchokera ku lactic acid yotengedwa kuchokera ku chimanga, nzimbe ndi mbewu zina, zomwe ndi zinthu zongowonjezedwanso, ndipo zimachepetsa kudalira zinthu zamafuta.
3. Ili ndi mpweya wabwino wolowa, mpweya wabwino wolowa komanso mpweya wabwino wolowa, komanso ili ndi mphamvu yolekanitsa fungo. Mavairasi ndi nkhungu nthawi zambiri zimamatira pamwamba pa pulasitiki yowola, kotero pali nkhawa zokhudza chitetezo ndi ukhondo. Komabe, PLA ndiye pulasitiki yokhayo yowola yomwe ili ndi mphamvu zabwino zotsutsana ndi mabakiteriya komanso zotsutsana ndi nkhungu.
Njira yowononga PLA
1. Hydrolysis: Gulu la ester la unyolo waukulu limasweka, motero kuchepetsa kulemera kwa mamolekyu.
2. Kuwonongeka kwa kutentha: chinthu chovuta chomwe chimayambitsa kupangika kwa mankhwala osiyanasiyana, monga mamolekyu opepuka ndi ma oligomer olunjika ndi ozungulira okhala ndi kulemera kosiyanasiyana kwa mamolekyu, komanso lactide.
3. Kuwonongeka kwa kuwala kwa dzuwa: Kuwala kwa ultraviolet kungayambitse kuwonongeka. Ichi ndi chifukwa chachikulu chomwe chimapangitsa kuti PLA iwonongeke ndi dzuwa m'mapulasitiki, m'mabokosi osungiramo zinthu, ndi m'mapepala ogwiritsira ntchito.
Kugwiritsa ntchito PLA m'munda wolongedza
Zipangizo za PLA zimagwiritsidwa ntchito m'magawo osiyanasiyana. Mu makampani opanga ma CD, filimu ya PLA imagwiritsidwa ntchito kwambiri popanga chakudya, zakumwa ndi mankhwala kuti ilowe m'malo mwa ma CD apulasitiki achikhalidwe, kuti akwaniritse cholinga choteteza chilengedwe komanso chokhazikika.
PACK MIC imapanga matumba obwezerezedwanso komanso opangidwa mwamakonda.
