Chithunzi cha PLA
PLA ndi mtundu wa mzere mawonekedwe Aliphatic Polyesters. PLA itha kugwiritsidwa ntchito mu phukusi lolimba la zipatso, ndiwo zamasamba, mazira, zakudya zophikidwa ndi zakudya zowotcha, zitha kugwiritsidwanso ntchito pakuyika masangweji, mabisiketi ndi mapaketi ena monga maluwa atsopano.
Mafotokozedwe Akatundu
Asidi wa Polylactic (PLA) amatha kusungunuka kukhala mpweya woipa ndi madzi pansi pa chilengedwe atatayidwa. Imakhala ndi kukana madzi abwino, makina, biocompatibility, imatha kutengeka ndi zamoyo, ndipo ilibe kuipitsa chilengedwe. Nthawi yomweyo, PLA imakhalanso ndi makina abwino. Lili ndi mphamvu zokhuza kwambiri, kusinthasintha kwabwino komanso kukhazikika kwamafuta, pulasitiki, kusinthika, kusasinthika, kutulutsa mpweya wabwino ndi nthunzi yamadzi, komanso kuwonekera bwino, anti-mildew, antibacterial, moyo wautumiki ndi zaka 2-3.
Mlozera wofunikira kwambiri wazinthu zopangira ma CD ndikuthekera kwa mpweya, ndipo gawo logwiritsira ntchito zinthuzi pakuyika lingadziwike molingana ndi kuthekera kosiyanasiyana kwa zinthu. Zida zina zomangirira zimafunikira mpweya wokwanira kuti upereke mpweya wokwanira kuzinthu; zinthu zina zonyamula katundu zimafuna chotchinga cha okosijeni potengera zinthu, monga zopangira zakumwa, zomwe zimafunikira zida zomwe zingalepheretse mpweya kulowa mu phukusi kuti ziletse nkhungu. zotsatira za kukula. PLA ili ndi chotchinga mpweya, chotchinga madzi, kuwonekera komanso kusindikiza kwabwino.
PLA ili ndi kuwonekera bwino komanso gloss, ndipo ntchito yake yabwino kwambiri ikufanana ndi cellophane ndi PET, zomwe sizipezeka m'mapulasitiki ena owonongeka. Kuwonekera ndi gloss wa PLA ndi 2 ~ 3 nthawi ya filimu wamba PP ndi nthawi 10 kuposa LDPE. Kuwonekera kwake kwakukulu kumapangitsa maonekedwe a kugwiritsa ntchito PLA ngati chinthu chokongoletsera chokongola. Mwachitsanzo, amagwiritsidwa ntchito popanga maswiti. Pakalipano, maswiti ambiri pamsika amagwiritsa ntchito mafilimu a PLA.
Maonekedwe ndi machitidwe a filimuyi yodzaza ndi yofanana ndi mafilimu opangira maswiti, omwe amawonekera kwambiri, kusungirako bwino kwa kink, kusindikiza ndi mphamvu, komanso katundu wabwino kwambiri wolepheretsa, zomwe zingathe kusunga bwino maswiti. Kampani ya ku Japan imagwiritsa ntchito mtundu wa "racea" PLA wa American Cakir Dow Polymer Company monga zopangira zinthu zatsopano, ndipo zoyikapo zimakhala zowonekera kwambiri. Toray Industries yapanga mafilimu ogwira ntchito a PLA ndi magawo pogwiritsa ntchito ukadaulo wake wa nano-alloy. Kanemayu ali ndi kutentha komweko komanso kukana kwamphamvu monga mafilimu opangidwa ndi petroleum, komanso ali ndi kukhathamira kwakukulu komanso kuwonekera.
PLA ikhoza kupangidwa kukhala zinthu zamakanema zowonekera kwambiri, zotchinga zabwino, kukhazikika bwino komanso makina amakina, ndipo zitha kugwiritsidwa ntchito pakuyika zipatso ndi ndiwo zamasamba. Ikhoza kupanga malo abwino osungiramo zipatso ndi ndiwo zamasamba, kusunga zochitika za moyo wa zipatso ndi ndiwo zamasamba, kuchepetsa ukalamba, ndi kusunga mtundu, fungo, kukoma ndi maonekedwe a zipatso ndi ndiwo zamasamba. Komabe, zikagwiritsidwa ntchito kuzinthu zenizeni zopangira chakudya, zosintha zina zimafunikira kuti zigwirizane ndi mawonekedwe a chakudyacho, kuti akwaniritse bwino pakuyika kwake.
PLA ikhoza kupanga malo ofooka acidic pamwamba pa mankhwala, omwe ali ndi maziko a antibacterial ndi antifungal. Ngati mankhwala ena antibacterial ntchito kuwonjezera, mlingo antibacterial oposa 90% angapezeke, amene angagwiritsidwe ntchito ma CD antibacterial katundu.
Poyerekeza ndi filimu ya LDPE, filimu ya PLA ndi filimu ya PLA/REO/TiO2, kutha kwa madzi a filimu yamagulu a PLA/REO/Ag ndikokwera kwambiri kuposa mafilimu ena. Zimatha kuchokera ku izi kuti zimatha kuteteza bwino mapangidwe a madzi osungunuka ndikukwaniritsa zotsatira zolepheretsa kukula kwa tizilombo toyambitsa matenda; nthawi yomweyo, imakhalanso ndi zotsatira zabwino kwambiri za bacteriostatic.
PET/PLA chilengedwe sheet extrusion line: JWELL imapanga parallel twin screw extrusion line ya PET/PLA sheet, mzerewu wokhala ndi degassing system, ndipo palibe chifukwa chowumitsa ndi crystallizing unit. Mzere wa extrusion uli ndi mphamvu zochepetsera mphamvu zamagetsi, njira yosavuta yopangira komanso kukonza kosavuta. Zomangira zokhala ndi magawo zimatha kuchepetsa kutayika kwa viscosity kwa utomoni wa PET/PLA, chowongolera chofananira komanso chowonda chapakhoma chimakweza kuziziritsa ndikuwongolera kuthekera ndi mtundu wa pepala. Mipikisano zigawo dosing wodyetsa akhoza kulamulira kuchuluka kwa zinthu namwali, yobwezeretsanso zinthu ndi mbuye mtanda ndendende, pepala chimagwiritsidwa ntchito thermoforming ma CD makampani.
