Chifukwa chiyani PLA ikukula kwambiri?

Zochuluka zopangira
Zopangira zomwe zimagwiritsidwa ntchito popanga asidi a polylactic (PLA) zimachokera kuzinthu zongowonjezedwanso monga chimanga, popanda kufunikira kwa zinthu zachilengedwe zamtengo wapatali monga mafuta kapena matabwa, motero zimathandizira kuteteza kuchepa kwamafuta.

Zapamwamba zakuthupi
PLA ndi oyenera njira zosiyanasiyana processing monga kuwomba akamaumba ndi thermoplastics, kupangitsa kuti zikhale zosavuta pokonza ndi ntchito zosiyanasiyana mankhwala pulasitiki, ma CD chakudya, kudya mabokosi chakudya, sanali nsalu nsalu, mafakitale ndi wamba nsalu, ndipo ali kwambiri Mawonekedwe abwino a msika.

Biocompatibility
PLA imakhalanso ndi biocompatibility yabwino kwambiri, ndipo mankhwala ake owonongeka, L-lactic acid, amatha kutenga nawo mbali mu metabolism yaumunthu.Zavomerezedwa ndi US Food and Drug Administration (FDA) ndipo zitha kugwiritsidwa ntchito ngati suture yachipatala, makapisozi obaya, ma microspheres, ndi implants.

Kupuma kwabwino
Filimu ya PLA imakhala ndi mpweya wabwino, mpweya wabwino, komanso mpweya woipa wa carbon dioxide, komanso uli ndi khalidwe la kudzipatula kwa fungo.Ma virus ndi nkhungu ndizosavuta kuzilumikiza pamwamba pa mapulasitiki owonongeka, kotero pali nkhawa zachitetezo ndi ukhondo.Komabe, PLA ndiye pulasitiki yokhayo yomwe imatha kuwonongeka ndi antibacterial komanso anti-mold.
 
Biodegradability
PLA ndi imodzi mwazinthu zomwe zafufuzidwa kwambiri zomwe zimatha kuwonongeka ku China ndi kunja, ndipo madera ake atatu akuluakulu omwe amagwiritsidwa ntchito ndi otentha ndi zosungiramo zakudya, zotayira pa tebulo, ndi zida zamankhwala.
 
PLA, yomwe makamaka imapangidwa kuchokera ku asidi achilengedwe a lactic, imakhala ndi biodegradability ndi biocompatibility, ndipo moyo wake umakhala ndi zotsatira zochepa kwambiri zachilengedwe kuposa zida zopangira mafuta.Imatengedwa kuti ndi yodalirika kwambiri yobiriwira yopangira ma CD kuti ipangidwe.
 
Monga mtundu watsopano wazinthu zachilengedwe zoyera, PLA ili ndi chiyembekezo chachikulu chamsika.Zake zabwino thupi katundu ndi chilengedwe ubwenzi mosakayikira kupanga PLA kwambiri ambiri m'tsogolo.
