Intshayelelo emfutshane yePLA

Malunga ne-PLA

I-PLA, ikwabizwa ngokuba yi-polylactic acid, i-polymerized esuka kwi-poly lactic acid.Iasidi yePolylactic inomgangatho ogqwesileyo wokubola, ukuhambelana nokufunxwa, ayiyotyhefu, ayiyokwenziwa ipholima imathiriyeli .lts imathiriyeli ekrwada yipolylactic acid, ethatyathwe ubukhulu becala ekubilisweni kwesitatshi, esifana necom kunye nerc.Inokufumaneka nakwi-cellulose, inkunkuma yasekhitshini okanye inkunkuma yeentlanzi.

I-PLA inoluhlu olubanzi lwezinto eziluhlaza, kunye neemveliso ezenziwe kuyo zingaxutywa ngokuthe ngqo okanye zitshiswe, ezinokuhlangabezana neemfuno zophuhliso oluzinzileyo. ukusetyenziswa kwayo ngokubanzi.

ukongeza, i-PLA ine-thermal-plasticity kwaye inokusetyenziswa kwiindawo ezininzi, ezifana nempahla yokupakisha, izihluzi, njl njl.

Xa kuthelekiswa neemveliso zepetrochemical zemveli, ukusetyenziswa kwamandla kwimveliso ye-polylactic acid kuphela i-20% ukuya kwi-50% yeemveliso zepetrochemical, kunye ne-carbon dioxide eveliswayo yi-50% kuphela yeemveliso zepetrochemical. ukunciphisa iingxaki zokusingqongileyo kunye namandla ehlabathi.

Iimpawu zePLA

1.Biodegradability

Xa kuthelekiswa neeplastiki zendabuko, i-polylactic acid inokutshatyalaliswa kwi-CO2 kunye ne-H2O nge-microorganisms kunye nokukhanya.Iimveliso zokuthotywa kwebhayoloji azinatyhefu kwaye azinabungozi kwaye aziyi kungcolisa okusingqongileyo.I-monomer yokuvelisa i-polylactic, enokuthi ivundiswe zizityalo ezifana nengqolowa yengqolowa kunye ne-sugar beet okanye uhlobo lwemveliso yezolimo.Ngoko ke, izinto eziluhlaza zokuvelisa i-polylactic acid ihlaziywa.Iasidi yePolylactic njengezinto ezisakhulayo ezinokubola zisetyenziswa ngokubanzi.

2. I-Bio-compatibility kunye ne-Absorb-ability

I-asidi ye-Polylactic inokuthi i-hydrolyzed nge-asidi okanye i-enzyme ukwenza i-lactic acid emzimbeni womntu.Njenge-metabolite yeeseli, i-polylactic acid inokuphinda ifakwe kwi-enzymes emzimbeni, ukuvelisa i-CO2 kunye ne-H2O.Ke ngoko, i-polylactic acid ayinayo ityhefu kwaye ayinabungozi emzimbeni womntu ngaphezu koko inokuhambelana kakuhle kwe-bio kunye ne-bio-absorb-ikhono, i-Polylactic acid iqinisekiswa yi-US Food and Drug Administration enokuthi isetyenziswe njenge-bio-material yokufakelwa ngaphakathi. abantu.

3. Ukwazi ukwenza izinto ngokwasemzimbeni

Njengemathiriyeli ye-polymer ye-thermoplastic, i-poly lactic acid ineplastiki elungileyo kunye neempawu zokusetyenzwa komzimba, ezinendawo ephezulu yokunyibilika, ukuqina okuhle kunye nokuguquguquka, kunye nobuchule obubalaseleyo bokwenza i-thermal.Iimathiriyeli ze-Poly lactic acid ezifana nemathiriyeli ye-polymer ezifana ne-polypropylene (PP), i-polystyrene(PS), kunye ne-polypropylene ether resin (PPO), inokucutshungulwa ngokukhupha, ukuzolula, kunye nokubumba ukuvuthela ngesitofu.
