Chii chinonzi PLA?Zvese Zvaunoda Kuziva
Wanga uchitsvaga imwe nzira yepetroleum-based mapurasitiki uye kurongedza?Musika wemazuva ano uri kuramba uchienda kune biodegradable uye eco-hushamwari zvigadzirwa zvakagadzirwa kubva kune zvinogonekazve zviwanikwa.
PLA firimuzvigadzirwa zvakakurumidza kuve imwe yeanonyanya kufarirwa biodegradable uye zvakatipoteredza-ane hushamwari sarudzo pamusika.Ongororo yemuna 2017 yakawana kuti kutsiva mapurasitiki ane petroleum nemapurasitiki ane bio-based anogona kuderedza kuburitswa kwemaindasitiri egreenhouse gasi ne25%.
Chii chinonzi PLA?
PLA, kana polylactic acid, inogadzirwa kubva kune chero shuga inovirisa.PLA zhinji inogadzirwa nechibage nekuti chibage chimwe cheshuga dzakachipa uye dzinowanikwa pasi rose.Zvisinei, nzimbe, mudzi wetapioca, mufarinya, uye sugar beet pulp ndezvimwe zvingasarudzwa.
Kufanana nezvinhu zvakawanda zvine chekuita nemakemikari, maitiro ekugadzira PLA kubva muchibage akaoma.Zvisinei, inogona kutsanangurwa mumatanho mashoma akatwasuka.
Zvigadzirwa zvePLA zvinogadzirwa sei?
Matanho ekutanga ekugadzira polylactic asidhi kubva kuchibage ndeaya anotevera:
1. Chekutanga chibage starch inofanira kuchinjwa kuva shuga kuburikidza nema mechanical process inonzi wet milling.Kugaya kwakanyorova kunopatsanura sitachi nembeu.Acid kana ma enzyme anowedzerwa kana zvikamu izvi zvaparadzaniswa.Zvadaro, vanopisa kushandura starch mu dextrose (aka shuga).
2. Zvadaro, dextrose inoviriswa.Imwe yedzakajairika nzira dzekuvirisa inosanganisira kuwedzera Lactobacillus bhakitiriya kune dextrose.Izvi, zvakare, zvinogadzira lactic acid.
3. Iyo lactic acid inozoshandurwa kuita lactide, ring-form dimer yelactic acid.Aya mamorekuru elactide anobatana pamwechete kugadzira mapolymer.
4. Mhedzisiro yepolymerization zvimedu zvidiki zve polylactic acid epurasitiki inogona kushandurwa kuita yakawanda yePLA zvigadzirwa zvepurasitiki.
Ndezvipi zvinobatsira zvePLA zvigadzirwa?
PLA inoda 65% shoma simba kugadzira pane zvechinyakare, petroleum-based mapurasitiki.Inoburitsawo 68% mashoma egreenhouse magasi.Uye handizvo chete:
The Environmental benefits:
Inofananidzwa nePET mapurasitiki - Anopfuura makumi mapfumbamwe neshanu muzana emapurasitiki epasi anogadzirwa kubva kugasi rechisikigo kana mafuta asina kuchena.Fossil mafuta-based plastics haasi ane ngozi chete;ivo zvakare chitubu chine magumo.Zvigadzirwa zvePLA zvinopa inoshanda, inovandudzwa, uye inofananidzwa kutsiva.
Bio-based- Zvishandiso zvechigadzirwa chebio-based zvakatorwa kubva mukurima zvakare kana zvirimwa.Nekuti zvese zvigadzirwa zvePLA zvinobva kune shuga starches, polylactic asidhi inoonekwa sebio-based.
Biodegradable- Zvigadzirwa zvePLA zvinowana mwero wepasi rose we biodegradation, zvinodzikisira pachizvarirwo pane kuungana mumarara.Zvinoda mamwe mamiriro kuti adzikise nekukurumidza.Mune maindasitiri composting nzvimbo, inogona kuparara mumazuva makumi mana nemashanu-90.
Haibudise utsi hune muchetura - Kusiyana nemamwe mapurasitiki, bioplastics haiburitse chero utsi hune muchetura kana hwapiswa.
Thermoplastic- PLA ndeye thermoplastic, saka inoumbwa uye inogadzirwa kana ichipisa kusvika pakunyungudika kwayo.Inogona kuomeswa uye jekiseni-kuumbwa mumhando dzakasiyana-siyana zvichiita kuti ive yakasarudzika sarudzo yekurongedza chikafu uye 3D kudhinda.
Zvokudya Kubata-kwatenderwa-Polylactic acid inotenderwa seInowanzo Kuzivikanwa seYakachengeteka (GRAS) polymer uye yakachengeteka pakubata chikafu.
Kuiswa kwechikafu kunobatsira:
Havana makemikari anokuvadza akafanana nemafuta epetroleum-based products
Akasimba semapurasitiki akawanda akajairika
Freezer-yakachengeteka
Makapu anogona kubata tembiricha inosvika 110°F (PLA midziyo inogona kubata tembiricha inosvika 200°F)
Isiri-chepfu, kabhoni-yakarerekera, uye 100% inogona kuvandudzwa
Munguva yakapfuura, apo vashandi vezvekudya vaida kuchinja kune eco-hushamwari kurongedza, vanogona kunge vakangowana zvinodhura uye subpar zvigadzirwa.Asi PLA inoshanda, inodhura, uye inogadzikana.Kuita shanduko kune izvi zvigadzirwa idanho rakakosha rekudzikisa bhizinesi rako rekudya kabhoni tsoka.
Kunze kwekurongedza chikafu, ndezvipi zvimwe zvinoshandiswa zvePLA?
Payakatanga kugadzirwa, PLA yaiita madhora mazana maviri kuita pondo imwe.Nekuda kwehunyanzvi hwekugadzira maitiro, inodhura isingasviki $1 paundi kugadzira nhasi.Nekuti haisisiri kudhura-kurambidza, polylactic asidhi ine mukana wekutorwa kukuru.
Izvo zvinonyanya kushandiswa zvinosanganisira:
3D kudhinda zvinhu filament
Kurongedza chikafu
Kurongedza zvipfeko
Packaging
Mumashandisirwo ese aya, dzimwe nzira dzePLA dzinopa mabhenefiti akajeka pamusoro pezvigadzirwa zvechinyakare.
Semuenzaniso, mu 3D printers, PLA filaments ndeimwe yezvisarudzo zvakakurumbira.Vane nzvimbo yakaderera yekunyungudika pane dzimwe sarudzo dzefilament, zvichiita kuti zvive nyore uye zvakachengeteka kushandisa.3D kudhinda PLA filament inoburitsa lactide, iyo inonzi isiri-chepfu fume.Saka, kusiyana nemafilament dzimwe nzira, inodhinda isingabudise chero chepfu inokuvadza.
Inopawo mamwe mabhenefiti akajeka mune zvekurapa.Inofarirwa nekuda kweiyo biocompatibility uye kuparara kwakachengeteka sezvo zvigadzirwa zvePLA zvinodzikira kuita lactic acid.Miviri yedu inongogadzira lactic acid, saka inowirirana.Nekuda kweizvi, PLA inowanzoshandiswa mumasisitimu ekuendesa zvinodhaka, maimplants ekurapa, uye engineering yetishu.
Munyika yefiber uye machira, vamiriri vanovavarira kutsiva mapolyester asingagone kuvandudzwa nePLA fiber.Micheka uye machira akagadzirwa nePLA faibha akareruka, anofema, uye anogona kushandiswazve.
PLA inoshandiswa zvakanyanya muindasitiri yekurongedza.Makambani makuru akadai seWalmart, Newman's Own Organics uye Wild Oats ese atanga kushandisa compostable package nekuda kwezvikonzero zvezvakatipoteredza.
Zvigadzirwa zvekurongedza zvePLA zvakaringana bhizinesi rangu here?
Kana bhizinesi rako parizvino richishandisa chero chezvinotevera zvinhu uye iwe uchida kusimudzira uye kuderedza bhizinesi rako kabhoni tsoka, saka PLA kurongedza isarudzo yakanaka.
