Chifukwa chiyani PLA ikukula kwambiri?

Zochuluka zopangira
Zida zomwe zimagwiritsidwa ntchito popanga polylactic acid (PLA) zimachokera kuzinthu zongowonjezedwanso monga chimanga, popanda kufunikira kwa zinthu zachilengedwe zamtengo wapatali monga mafuta kapena nkhuni, motero zimathandiza kuteteza mafuta omwe akucheperachepera.

Zapamwamba zakuthupi
PLA ndi yoyenera pa njira zosiyanasiyana zopangira zinthu monga kuwomba kuwombera ndi thermoplastics, zomwe zimapangitsa kuti zikhale zosavuta kuzikonza ndikugwiritsanso ntchito pazinthu zambiri zapulasitiki, kulongedza zakudya, mabokosi a chakudya chofulumira, nsalu zopanda nsalu, nsalu za mafakitale ndi za anthu wamba, ndipo zimakhala ndi msika wodalirika kwambiri.

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 komanso kunja, ndipo madera ake atatu akuluakulu omwe amagwiritsidwa ntchito ndi otentha ndi zopangira chakudya, 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.
