Kodi PLA Non Woven ndi chiyani

Polylactic acid(PLA) ndi chinthu chatsopano chomwe chimatha kuwonongeka chomwe chimagwiritsa ntchito zinthu zopangira wowuma zomwe zimachotsedwa kuzinthu zongowonjezwdwanso za mbewu (monga chimanga).Wowuma zopangira zopangira zimasanjidwa kuti zitenge shuga, zimafufutidwa ndi shuga ndi mitundu ina kuti zipange lactic acid ndi kuyera kwambiri, ndiye kuti kuchuluka kwa PLA kumapangidwa ndi njira yopangira mankhwala.Iwo ali biodegradability wabwino, ndipo pambuyo ntchito kuti akhoza kuonongeka kotheratu ndi tizilombo m'chilengedwe, potsiriza kutulutsa mpweya woipa ndi madzi, amene saipitsa chilengedwe ndipo n'kopindulitsa kwambiri kuteteza chilengedwe.So monga ife tonse tikudziwa，PLA amadziwika kuti chilengedwe zinthu zaubwenzi.

Ndi kukwezedwa padziko lonse lapansi kwa ziletso za pulasitiki, PLA ikugwiritsidwa ntchito mochulukira mumitundu yosiyanasiyana yazinthu zamapulasitiki, monga zikwama zonyamula, mabokosi azakudya otayika ndi matumba omwe sanalukidwe.

PLA nonwovens kungakhale 100% kuwonongeka mu chilengedwe, ndi applicability wabwino, osati oyenera kusoka yokumba, komanso oyenera akupanga kuwotcherera sanali nsalu thumba kupanga makina, koma chifukwa cha mphamvu ndi malire, kotero mtengo ndi apamwamba kuposa PP sanali nsalu , kotero kuvomereza msika si mkulu, koma kukhulupirira kuti ndi kusintha kwa luso PLA kupanga ndi kukula kwa sikelo kupanga, ndi PLA adzakhala waukulu zopangira ma CD ma CD.
