Polylactic acid (PLA) waa walxo cusub oo noole ku salaysan oo dib loo cusboonaysiin karo, kaas oo laga sameeyay maaddooyinka istaarijka oo ay soo jeediyaan khayraadka dhirta la cusboonaysiin karo (sida galleyda iyo cassava).Waxyaabaha ceeriin ee istaarijka ah ayaa la sacchardeeyay si loo helo gulukoos, ka dibna lactic acid nadiif ah oo sarreeya ayaa lagu sameeyay halsano gulukoos iyo noocyo gaar ah, ka dibna POlylactic acid oo leh miisaan kelli gaar ah ayaa lagu soo koobay kiimikada kiimikada.Waxay leedahay biodegradability wanaagsan.Isticmaalka ka dib, waxa gebi ahaanba hoos u dhigi kara nooleyaal dabiici ah oo ku jira xaalado gaar ah, oo ugu dambeyntii dhalin kara kaarboon laba ogsaydh iyo biyo.Ma wasakhayso deegaanka, taas oo faa'iido badan u leh ilaalinta deegaanka oo loo aqoonsan yahay inay tahay wax deegaanka u wanaagsan.Shiinaha PP Qiimaha Fabric Nonwoven
PLA,sidoo kale la mid ah hal noocPET spunbond,waxay leedahay dabacsanaan aad u fiican, jilicsanaan, nuugista qoyaanka iyo hawo-mareenka hawada, bacteriostasis dabiiciga ah iyo maqaarka hubinta asiidhka daciifka ah, caabbinta kulaylka wanaagsan iyo caabbinta UV.
PLA dhamaantood waxay u qornaayeen sida: polylactic acid
Polylactic acid, oo sidoo kale loo yaqaan polylactide, ayaa iska leh qoyska polyester-ka.Polylactic acid (PLA) waa polymer laga helay polymerization of lactic acid sida alaabta ugu weyn ee ceeriin.Ilaha alaabta ceeriin ayaa ku filan oo dib loo warshadayn karaa.Waxay inta badan u isticmaashaa galleyda iyo kasaafada sida alaabta ceeriin.Habka wax soo saarka ee PLA waa wasakh la'aan, badeecaduna waa la baabi'in karaa si loo xaqiijiyo wareegga dabiiciga ah, sidaas darteed waa wax ku habboon polymer cagaaran.
Polylactic acid waxay leedahay xasilloonida kulaylka wanaagsan, heerkulka processing 170 ~ 230 ℃, iska caabin dareere wanaagsan, waxaa lagu baaraandegi karaa siyaabo kala duwan, sida extrusion, spinning, iskala biaxial, irbaynta dharbaaxo.Alaabooyinka ka samaysan polylactic acid ma aha oo kaliya biodegradable, laakiin sidoo kale waxay leeyihiin biocompatibility wanaagsan, dhalaalid, hufnaan, dareemo iyo caabbinta kulaylka.Waxa kale oo ay leeyihiin iska caabin bakteeriyada qaarkood, olol retardant iyo UV iska caabin ah, si ay si ballaaran loo isticmaalo sida alaabta baakadaha, fiilooyinka iyo nonwovens, iwm. Hadda, waxa inta badan loo isticmaalaa in dharka (nigisyada, dharka sare), warshadaha (dhismaha, beeraha, kaynta). , warqad samaynta) iyo caafimaadka iyo caafimaadka.
