Nezve PLA
PLA, inozivikanwawo sepolylactic asidhi inonzi polymerized kubva ku poly lactic acid.Polylactic asidhi ine yakanakisa biodegradability, kugarisana uye kupfekwa, haina chepfu, isiri yekugadzira polymer material .lts raw material is polylactic acid, iyo inonyanya kutorwa kubva mukuvirisa starch, secom uye rc .Inogonawo kuwanikwa kubva kune cellulose, marara ekicheni kana marara ehove.
PLA ine huwandu hwakasiyana hwezvinhu zvakasvibirira, uye zvigadzirwa zvinogadzirwa kubva mairi zvinogona kuve zvakanangana necompost kana kupiswa, izvo zvinogona kusangana nezvinodiwa zvekusimudzira budiriro Kujeka kwakanaka uye kumwe kuoma, bio-compatibility uye kupisa-kudzivirira kwePLA ndizvo zvikonzero zvikuru. nokuda kwekushandiswa kwayo kwakapararira.
uyezve, PLA ine thermal-plasticity uye inogona kuiswa kune akawanda minda, senge kurongedza zvinhu, fillers, etc.
Kana ichienzaniswa neyakajairwa petrochemical zvigadzirwa, simba rinoshandiswa mukugadzirwa kwepolylactic acid inongova 20% kusvika 50% yezvigadzirwa zvepetrochemical, uye carbon dioxide inogadzirwa inongova 50% yezvigadzirwa zvepetrochemical. kuderedza matambudziko epasi rose ezvakatipoteredza uye simba.
Zvimiro zvePLA
1.Biodegradability
Kuenzaniswa nemapurasitiki echinyakare, polylactic asidhi inogona kuderedzwa kuita CO2 neH2O nema microorganisms uye chiedza.lts bio-degradation zvigadzirwa hazvina chepfu uye hazvikuvadze uye hazvisvibise nharaunda.Iyo monomer yekugadzira polylactic, iyo inogona kuviriswa nezvirimwa zvakaita segorosi mupunga uye shuga beet kana zvekurima mhando zvigadzirwa.Naizvozvo, iyo mbishi yekugadzira polylactic asidhi inodzokororwa.Polylactic asidhi sechinhu chiri kubuda biodegradable zvinhu zvinoshandiswa zvakanyanya.
2. Bio-kuenderana uye Absorb-kugona
Polylactic asidhi inogona kuve hydrolyzed neasidhi kana enzyme kugadzira lactic acid mumuviri wemunhu.Semetabolite yemasero, polylactic acid inogona kuwedzererwa ne enzymes mumuviri, kugadzira CO2 uye H2O.Naizvozvo, polylactic asidhi haina chepfu uye haina kukuvadza kumuviri wemunhu uye ine yakanaka bio-compatibility uye bio-absorb-kugona, Polylactic acid inosimbiswa neUS Food and Drug Administration inogona kushandiswa sebio-material yekuisirwa mukati. vanhu.
3. Physically Machinable
Seye thermoplastic polymer zvinhu, poly lactic acid ine yakanaka plasticity uye yemuviri kugadzirisa zvivakwa, ine yakakwirira yekunyungudika, yakanaka elasticity uye kuchinjika, uye yakanakisa yekupisa kuumba kugona.Poly lactic acid zvinhu zvakaita sepolymer zvinhu zvakaita sepolypropylene (PP), polystyrene(PS), uye polypropylene ether resin (PPO), inogona kugadzirwa neextrusion, kutambanudza, uye jekiseni kuvhuvhuta.
