Iimveliso
Breathble pla spunbond nonwoven
I-Polylactic acid (i-PLA) luhlobo olutsha lwezinto ezinokubola ezenziwe nge-biodegradable ezenziwe kwi-starch ephuma kwimithombo yezityalo ezivuselelekayo ezifana nombona. Izinto zesitatshi ekrwada zihlanjululwa ukuze kufunyanwe iswekile, ethi emva koko ivundiswe ngeentlobo ezithile ukuvelisa iasidi ye-lactic ecocekileyo. Emva koko, ubunzima obuthile bemolekyuli ye-polylactic acid buqulunqwe ngeendlela zokudityaniswa kweekhemikhali. Ine-biodegradability efanelekileyo kwaye inokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo emva kokusetyenziswa, ekugqibeleni ivelise i-carbon dioxide kunye namanzi ngaphandle kokungcolisa indalo.
Oku kuluncedo kakhulu ekukhuseleni okusingqongileyo kwaye kubonwa njengesixhobo esinobungani nokusingqongileyo. Ukunyamekela uMhlaba, sinoxanduva. Ngokweengxelo zeendaba, ukukhutshwa kwekharbon diokside emhlabeni kulindeleke ukuba kunyuke ukuya kutsho kuma-60 ℃ ngo-2030. Indlela yokunyanga iiplastiki eziqhelekileyo isatshisa nokutshiswa, nto leyo ebangela ukuba kukhutshelwe umoya omkhulu weegesi zegreenhouse. Iiplastiki ze-Polylactic acid, kwelinye icala, zingcwatywe emhlabeni ukuze zithotywe, zivelise i-carbon dioxide engena ngokuthe ngqo kumhlaba we-organic matter okanye ifunnwe zizityalo, ngaphandle kokukhutshwa emoyeni okanye kubangele i-greenhouse effect.
Iimpawu ze-PLA ye-polylactic acid engalukiweyo ilaphu
Ubungqina bokufuma, bunokuphefumla, bubhetyebhetye, bukhaphukhaphu, abutshi, kulula ukubola, abunatyhefu kwaye alucaphuki, lutyebile ngombala, lunokuphinda lusetyenziswe.
Umzekelo wokusetyenziswa kwelaphu elingalukwanga le-PLA
Ukuthatha ukusetyenziswa kwamalaphu angalukwanga kwiinkalo zonyango kunye nempilo njengomzekelo, amalaphu angalukwanga e-PLA awahlangabezi ngokupheleleyo kuphela iimfuno zokhuseleko kunye nokusetyenziswa kwezixhobo zokukhusela ezilahlayo, kodwa zinika imveliso ngeempawu ezintsha eziluhlaza kunye nokusingqongileyo. Emva kokusetyenziswa, inokuthi i-biodegraded ngokupheleleyo phantsi kweemeko zomgquba kwiinyanga ezimbalwa, kungekhona nje ngaphandle kokubangela nawuphi na umthwalo kwindalo, kodwa nokuthatha inxaxheba kumjikelezo wendalo.
Ukongeza, ilaphu le-polylactic acid inwebu yinto entsha esekwe kwibhayoloji enemvakalelo yesandla esithambileyo, i-adsorption eyomeleleyo, ukugcinwa komswakama, ukuphefumla kunye ne-bacteriostasis. Yinto esulungekileyo, ekhuselekileyo, esempilweni kwaye ikufutshane nolusu lwemathiriyeli ekumgangatho ophezulu. Ineempawu ezininzi zebhayoloji ezingenakuthelekiswa nezinye ii-substrate, kwaye iyindawo efanelekileyo yobuso bemaski yomgangatho ophezulu.
