Poly Lactic Acid ipolymer inowanikwa ne polymerizing lactic acid seyakanyanya mbishi zvinhu uye rudzi rutsva rwe biodegradable zvinhu.Naizvozvo,PLA shindaishinda inochengetedza zvakatipoteredza.
Pane chikonzero nei iyo inonyanya kufarirwa uye inoshandiswa zvakanyanya 3D kudhinda zvinhu zveFDM maprinta iri PLA.Zvichienzaniswa nezvimwe zvinhu, zviri nyore kudhinda, izvo zvinoita kuti ive yakanaka filament yeamateurs.Saizvozvowo, zvinowanzodavirwa izvozvoPLA filamentyakasimba uye yakachengeteka kupfuura zvimwe zvinhu.Kufungidzira uku kunobva kupi?Ko ini kugarika kwe100% zvakatipoteredza-riendly PLA?Tevere tichatarisa pane zvine chekuita nePLA.
1. PLA inogadzirwa sei?
PLA, inozivikanwawo sePoly Lactic Acid, inowanikwa kubva kune zvinogonekazve zvechisikigo zvinhu zvakaita sechibage.Bvisa starch (glucose) kubva mumiti uye shandura iyo kuva glucose nekuwedzera ma enzymes.Ma microorganisms anoivirisa kuita lactic acid, inozoshandurwa kuita polylactide.Polymerization inogadzira cheni refu-cheni mamorekuru ane zvimiro zvakafanana neaya epetroleum-based polymers.
2. Ko “PLA’s biodegradable and compostable” zvinorevei?
Mazwi ekuti "zvinoodza uye zvinosanganiswa" uye musiyano wavo wakakosha uye kazhinji haunzwisisike.Jan-Peter Willie akatsanangura kuti: “Vanhu vakawanda vanovhiringidza “zvinoodza” ne“zvinoita manyowa.”Muchidimbu, "biodegradable" zvinoreva kuti chinhu chinogona kuomeswa, nepo "Compostable" kazhinji zvinoreva kuti maitiro aya anozoguma nekuita manyowa.
Pasi pemamwe mamiriro eanaerobic kana aerobic, "biodegradable" zvinhu zvinogona kuora.Nekudaro, zvinenge zvese zvinhu zvichaora nekufamba kwenguva.Naizvozvo, iwo chaiwo mamiriro ezvakatipoteredza ayo ari biodegradable anofanira kutsanangurwa zvakajeka.Kompositi inzira yekugadzira.Zvinoenderana neEuropean standard EN13432, kana mukati memwedzi mitanhatu muindasitiri yecomposting chirimwa, ingangoita 90% yepolymer kana packaging inoshandurwa kuita kabhoni emissions nema microorganisms, uye iyo yakanyanya kunaka yekuwedzera i1%, iyo polymer kana kurongedza. inonzi "compostable".Hunhu hwepakutanga hahukuvadzi.Kana kuti tinogona kutaura muchidimbu: "Yose composting inogara ichisvibiswa, asi kwete yose biodegradation is composting".
3. PLA shinda inonyatsoenderana nemhoteredzo here?
Kana uchisimudzira PLA zvinhu, izwi rekuti "biodegradable" rinowanzoshandiswa, izvo zvinoratidza kuti PLA, semarara emukicheni, inogona kuora mucompost yemumba kana nharaunda yakasikwa.Zvisinei, izvi hazvisizvo.PLA filament inogona kutsanangurwa sezvinongoparara PLA filament, asi pasi pemamiriro chaiwo ekugadzirwa kwemaindasitiri, munyaya iyi, zvakanyanya kufanira kutaura kuti iyo inonzi biodegradable polymer.Mamiriro ekuita manyowa eindasitiri, kureva pamberi pehudiki, kudzora tembiricha uye hunyoro chinhu chinodiwa kuti PLA iparare.Florent Port akatsanangura.Jan-Peter Willie akawedzera kuti: "PLA inoumbwa, asi inogona kushandiswa chete mumaindasitiri ekugadzira manyowa."
Pasi peaya maindasitiri ecomposting mamiriro, PLA inogona kuomeswa mukati memazuva kusvika kumwedzi.Tembiricha inofanira kunge iri pamusoro pe55-70ºC.Nicholas akasimbisawo kuti: "PLA inogona chete kuomeswa pasi pemamiriro ekugadzira manyowa."
4. PLA inogona kushandiswazve here?
Sekureva kwenyanzvi nhatu, PLA pachayo inogona kushandiswazve.Zvisinei, Florent Port akataura kuti: “Parizvino hapana kuunganidzwa kwetsvina yePLA yekudhinda kwe3D.Kutaura zvazviri, chiteshi chemarara chepurasitiki chazvino chinonetsa kusiyanisa PLA kubva kune mamwe mapolymers (akadai sePET (mabhodhoro emvura).” Naizvozvo, nehunyanzvi, PLA inogona kudzokororwa, kunze kwekunge chigadzirwa chakatevedzana chine PLA chete uye chisina kusvibiswa nemamwe mapurasitiki. .”
5. PLA corn filament ndiyo filament ine hushamwari hwakatipoteredza here?
Nicolas Roux anotenda kuti hapana imwe nzira inogoneka kune chibage, ”Nehurombo, handizive chibage chakasvibira uye chakachengeteka, chingave chichaburitsa zvidimbu muvhu kana mugungwa kana kukwanisa kuzvisvibisa.Ndinofunga kuti pakusarudza zvinhu, vagadziri vanosarudza kushandisa filaments nekuchengetedzwa kwakabatana nenzira ine mutoro.
Jiayi's100% biodegradable PLA shindayakunda kurumbidzwa kwakabvumirana pakati pevatengi.kana uchitsvaga shinda inoshatisa inoshambidzika ine hushamwari, unogona kutibata
