M'malo osinthika aukadaulo wokhazikika , makhadi a RFID akhala gawo lofunikira pa moyo watsiku ndi tsiku, omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana monga kuwongolera mwayi wopeza, njira zolipirira, ndi chizindikiritso. Komabe, makhadi amtundu wa RFID amapangidwa kuchokera kuzinthu zosawonongeka, zomwe zimapangitsa kuti zinyalala zapulasitiki ziwonongeke komanso kuwononga chilengedwe. Pofuna kuthana ndi vutoli, makampani ambiri ayamba kupanga makadi a RFID PLA omwe angawonongeke - njira yatsopano, yothandiza zachilengedwe yomwe imagwiritsa ntchito Polylactic Acid (PLA) , polima yowonongeka yomwe imachokera kuzinthu zowonjezera monga chimanga chowuma kapena nzimbe. Kusinthaku kwa makhadi a RFID ochezeka ndi zachilengedwe kumagwirizana ndi zoyesayesa zapadziko lonse lapansi ndipo zikusintha momwe timayendera ukadaulo wamakono wamakhadi.
Khadi losawonongeka la RFID PLA ndi khadi la Radio Frequency Identification (RFID) lopangidwa kuchokera ku mapepala a PLA m'malo mwa pulasitiki wamba. PLA (Polylactic Acid) ndi polima yemwe amatha kuwonongeka kuchokera ku zomera zomwe zingangowonjezedwanso, makamaka wowuma wa chimanga, nzimbe, kapena zinthu zina zachilengedwe. Mapangidwe a PLA amalola khadi kuwola mwachilengedwe pansi pamikhalidwe ya kompositi yamakampani, osasiya zotsalira zovulaza.
PLA imapereka maubwino angapo poyerekeza ndi mapulasitiki achikhalidwe monga PVC (polyvinyl chloride) kapena PETG (glycol-modified polyethylene terephthalate). Zinthu wambazi siziwola, zomwe zimapangitsa kuti pakhale zinyalala zachilengedwe. Kumbali inayi, PLA ndi 100% yowola ndipo imachokera kuzinthu zongowonjezwdwa. Izi zimapangitsa kukhala njira yabwino kwambiri yochepetsera kuchuluka kwa mpweya ndi zinyalala m'mafakitale omwe amadalira kwambiri makadi a RFID , kuphatikiza mayendedwe, mabanki, ndi chitetezo.
Phindu lowoneka bwino la makhadi a RFID PLA owonongeka ndi momwe amakhudzira chilengedwe . Ndi zinyalala za pulasitiki zapadziko lonse lapansi zikufikira pamlingo wowopsa, kugwiritsa ntchito PLA kumachepetsa zinyalala zapulasitiki kwambiri. Zipangizo za PLA zimachokera kuzinthu zachilengedwe, zongowonjezwdwa ndikuwonongeka mwachangu poyerekeza ndi mapulasitiki achikhalidwe.
PLA imachokera ku biomass yongowonjezedwanso, monga wowuma wa chimanga kapena nzimbe , yomwe imakhala yokhazikika kuposa mapulasitiki opangidwa ndi petroleum. Popeza sichidalira mphamvu zotsalira zamafuta, kupanga PLA kumagwirizana ndi zolinga zachitukuko chokhazikika..
Chimodzi mwazodetsa nkhawa ndi makadi achikhalidwe a PVC ndi kawopsedwe kawo . PVC imatulutsa mankhwala owopsa panthawi yopanga, kutaya, ndi kuwonongeka, zomwe zikuwopseza thanzi la anthu komanso chilengedwe. Mosiyana ndi zimenezi, PLA ndi yopanda poizoni ndipo simatulutsa mankhwala ovulaza panthawi ya kuwonongeka.
Pansi pa kompositi yamafakitale, makhadi a PLA amawonongeka kukhala zinthu zachilengedwe pakanthawi kochepa, zomwe zimawapangitsa kukhala compostable . Izi zikugwirizana ndi zoyesayesa zochepetsera zinyalala zotayira kutayira komanso kuchepetsa mpweya wotenthetsera mpweya wochokera ku njira zoyendetsera zinyalala.
Ngakhale kuti akhoza kuwonongeka, makhadi a RFID PLA amakhalabe ndi magwiridwe antchito ofanana ndi omwe sangawonongeke. Zitha kuphatikizidwa ndi tchipisi tating'ono ta RFID ndikupereka kulimba kofanana ndi magwiridwe antchito osiyanasiyana, kuchokera pamakhadi anzeru kupita kumayendedwe owongolera..
Kapangidwe ka makhadi a PLA kumayamba ndikutulutsa asidi wa polylactic kuchokera kuzinthu zachilengedwe monga chimanga chowuma kapena nzimbe . Zinthuzo zimasinthidwa kukhala mapepala owonda, omwe amakhala ngati gawo lapansi la tchipisi ta RFID . Mapepala a PLAwa amapangidwa ndi laminated, kusindikizidwa, ndi encoded ndi luso la RFID kuti apange makhadi a RFID omwe amatha kuwonongeka..
Kusiyana kwakukulu pakupanga kumeneku poyerekeza ndi makadi achikhalidwe a RFID kuli pakugwiritsa ntchito mapepala a PLA osawonongeka m'malo mwa mapulasitiki osawonongeka ngati PVC. Makhadi a PLA amatha kupangidwa pogwiritsa ntchito zida ndi njira zomwezo monga makhadi wamba, zomwe zimapangitsa kuti zikhale zosavuta kuti opanga asinthe njira zokhazikika zopangira.
Ndi chidziwitso chochuluka chokhudza kukhazikika, makhadi owonongeka a RFID PLA akutchuka mwachangu m'magawo angapo:
Zoyendera zapagulu padziko lonse lapansi zimagwiritsa ntchito makadi a RFID pofikira mabasi, masitima apamtunda, ndi masitima apamtunda. Posinthira ku makhadi a PLA RFID , oyang'anira zamayendedwe amatha kuchepetsa zinyalala zawo zapulasitiki. Kukhazikika komanso magwiridwe antchito a makhadi a PLA kuwapangitsa kukhala abwino kugwiritsidwa ntchito kwanthawi yayitali pamakina osalumikizana nawo.
Mabanki ndi mabungwe azachuma akuchulukirachulukira kuzinthu zokhazikika , kuphatikiza kugwiritsa ntchito mabanki owonongeka ndi makhadi a ngongole . Ndi makhadi a RFID PLA osawonongeka , mabungwewa amatha kupatsa makasitomala njira zina zokometsera zachilengedwe popanda kupereka chitetezo kapena magwiridwe antchito.
Mabizinesi ndi mabungwe atha kuchepetsa kuwononga chilengedwe popereka makhadi ofikira a RFID osawonongeka . Makhadiwa ndi olimba komanso amagwira ntchito ngati makhadi amtundu wa RFID koma ndi ochezeka kwambiri ndi chilengedwe. Kuphatikiza apo, amapereka makampani mwayi wowonetsa kudzipereka kwawo pakukhazikika, zomwe ndizofunikira kwambiri kwa ogula ndi ogwira ntchito.
Ukadaulo wa RFID umagwiritsidwa ntchito nthawi zambiri popereka matikiti kuti azitha kuyang'anira kuchuluka kwa anthu komanso mwayi wopezeka pamakonsati, zikondwerero, ndi zochitika zamasewera. Potengera makadi a PLA RFID , okonza zochitika amatha kuchepetsa kukhudzidwa kwawo kwa chilengedwe, makamaka pazochitika zazikulu zomwe matikiti masauzande a RFID amagawidwa.
Ngakhale maubwino a makhadi a PLA RFID akuwonekera, pali zovuta zina pakutengera ana ambiri. Mwachitsanzo, PLA ndiyokwera mtengo kupanga kuposa zida zamapulasitiki zachikhalidwe, zomwe zitha kukulitsa mtengo wopanga. Kuonjezera apo, PLA ndi biodegradable pansi zinthu zina (ie, mafakitale kompositi), ndipo si malo onse ali ndi zomangamanga zofunika kompositi PLA zipangizo moyenera. Komabe, zopindulitsa zomwe zakhala zikuchitika kwanthawi yayitali zimaposa zovuta izi, zomwe zimapangitsa makhadi a RFID PLA kukhala yankho labwino kwa mabizinesi omwe akufuna kuchepetsa momwe chilengedwe chimakhalira.
Pamene dziko likupita ku njira zothetsera mavuto, makhadi a RFID PLA omwe amatha kuwonongeka ndi chilengedwe amapereka njira yothandiza zachilengedwe kusiyana ndi makhadi apulasitiki achikhalidwe. Makhadiwa amaphatikiza luso lamakono la RFID ndi ubwino wa PLA's biodegradability , kuwonetsetsa kuti ntchito zake zikuyenda bwino ndikuchepetsa kuwononga chilengedwe. Mafakitale ambiri akazindikira kufunikira kwa atha , makhadi a RFID okhazikika kukhala chizolowezi, m'malo mwa zosankha zomwe sizingawonongeke ndikuwonjezera tsogolo labwino.
