Ko PLA inogona kuora here?
•Polylactic acid, inozivikanwawo sePLA, yave iripo kwemakore akawanda. Zvisinei, vagadziri vakuru vePLA vachangobva kupinda mumusika mushure mekuwana mari kubva kumakambani makuru anoda kutsiva mapurasitiki ekugadzira. Saka, PLA inogona kuora here?
•Kunyange zvazvo mhinduro yacho isiri nyore, takasarudza kupa tsananguro uye kukurudzira kuti vaverengi vawedzere. PLA haiparadzike, asi inoora. Ma enzyme anogona kuputsa PLA haawanikwe munzvimbo dzakatikomberedza. Proteinase K ienzyme inokonzera kuparara kwePLA kuburikidza ne hydrolysis. Vatsvaguri vakaita saWilliams muna 1981 naTsuji naMiyauchi muna 2001 vakaongorora nyaya yekuti PLA inogona kuora here. Mhedzisiro yavo inokurukurwa mubhuku rinonzi Biomaterials Science: An Introduction to Medical Materials uye yakataurwa pamusangano weEuropean Biomaterials Society. Sekureva kwemashoko aya, PLA inodzorwa zvakanyanya ne hydrolysis, isina chekuita nechero biologic agents. Kunyange hazvo vanhu vazhinji vangafunga kuti PLA inogona kuora, zvakakosha kuziva izvi.
•Kutaura zvazviri, hydrolysis yePLA neproteinase K haiwanzoitiki zvekuti haina kukosha zvekuti inofanira kukurukurwa zvakanyanya mune zvesainzi yezvinhu zvipenyu. Tinovimba kuti izvi zvichajekesa nyaya dzine chekuita nekuora kwePLA uye ticharamba tichiedza kupa mhinduro dzakanakisa kune zvinodiwa nepurasitiki yako isingakuvadzi nharaunda uye inogona kuora.
Imhedziso:
PLA ipurasitiki inoora inoshandiswa zvakanyanya muzvinhu zvezuva nezuva zvakaita semabhegi nemakapu anoraswa. Zvisinei, inogona kuora chete mumabasa ekugadzira manyowa kana munzvimbo dzisina mweya, zvichiita kuti kuora kwevhu munzvimbo dzakajairika kuve kwakaoma. Zvidzidzo zvakasimbisa kuti PLA haiori zvakanyanya munzvimbo dzegungwa.
