Ku saabsan PLA
PLA, oo sidoo kale loo yaqaan polylactic acid oo laga sameeyay polylactic acid.Polylactic acid waxay leedahay biodegradability heer sare ah, waafaqid iyo nuugista, waa wax aan sun ahayn, maaddada polymer synthetic .lts alaabta ceeriin waa polylactic acid, taas oo inta badan laga soo qaatay halsano ee istaarijka, sida com iyo rc.Waxa kale oo laga heli karaa cellulose, qashinka jikada ama qashinka kalluunka.
PLA waxay leedahay noocyo kala duwan oo alaabta ceeriin ah, iyo alaabooyinka laga sameeyay si toos ah ayaa loo koobi karaa ama la gubi karaa, taas oo buuxin karta shuruudaha horumarinta joogtada ah Hufnaanta wanaagsan iyo adkaanta qaarkood, bio-ku-waafajinta iyo kuleylka kuleylka ee PLA ayaa ah sababaha ugu waaweyn. codsigeeda baahsan.
Intaa waxaa dheer, PLA waxay leedahay kulayl-balaastik waxaana lagu dabaqi karaa meelo badan, sida alaabta wax lagu duubo, buuxinta, iwm.
Marka la barbardhigo alaabada petrochemical ee dhaqameed, isticmaalka tamarta ee wax soo saarka polylactic acid waa kaliya 20% ilaa 50% alaabta petrochemical, iyo kaarboon dioxide ee la soo saaro waa 50% kaliya ee alaabta petrochemical. Sidaa darteed, horumarinta alaabta polylactic acid waa lagama maarmaan si loo yareeyo dhibaatooyinka deegaanka iyo tamarta caalamka.
Tilmaamaha PLA
1.Biodegradability
Marka la barbar dhigo balaastikada dhaqameed, polylactic acid waxaa hoos u dhigi kara CO2 iyo H2O by microorganisms iyo iftiinka.Alaabooyinka xaalufka nooluhu waa kuwo aan sun ahayn oo aan waxyeello lahayn, mana wasakhayn doonaan deegaanka.monomer-ka soo saarida polylactic, kaas oo lagu khamiirin karo dalagyada sida bariiska sarreenka iyo dabocase sonkorta ama noocyada beeraha.Sidaa darteed, alaabta ceeriin ee soo saarida polylactic acid waa la cusboonaysiin karaa.Polylactic acid sida walxo biodegradable ah oo soo baxaya ayaa si ballaaran loo isticmaalaa.
2. Waafaqsanaanta noole iyo kartida nuugista
Polylactic acid waxa lagu hydrolyzed karaa aashito ama ensaymes si ay u sameeyaan lactic acid ee jidhka bini'aadamka.Sida dheef-shiid kiimikaad ee unugyada, polylactic acid waxaa lagu sii kordhin karaa enzymes-ka jirka, si loo soo saaro CO2 iyo H2O.Sidaa darteed, polylactic acid waa mid aan sun ahayn oo aan waxyeello u lahayn jidhka bini'aadamka sidoo kale waxay leedahay iswaafajin wanaagsan oo bio-nuugista, Polylactic acid waxaa shahaado ka ah Maamulka Cuntada iyo Dawooyinka ee Maraykanka oo loo isticmaali karo sidii maaddo-bio-nololeedka loogu talagalay galinta aadanaha.
3. Jir ahaan Machin
Maaddada thermoplastic polymer-ka, poly lactic acid waxay leedahay caag wanaagsan iyo sifooyin wax-qabad jireed, oo leh bar dhalaaleed sare, dabacsanaan wanaagsan iyo dabacsanaan, iyo awood heerkul sare leh.Qalabka lactic acid-ka ah sida walxaha polymer sida polypropylene (PP), polystyrene (PS), iyo polypropylene ether resin (PPO), ayaa lagu farsamayn karaa extrusion, kala bixin, iyo qaabaynta irbado.
