Polylactic acid (PLA) chinhu chitsva chebio-based uye chinodzoreredzwa chebiodegradable material, icho chinogadzirwa kubva kune sitarch zvinhu zvinokurudzirwa nezvinogadzirwazve chirimwa (sechibage necassava).Starch mbishi zvinhu zvakaiswa saccharized kuti zviwane shuga, uyezve kuchena kwakanyanya lactic acid yakagadzirwa nekuviriswa kweglucose uye mamwe madhiri, uyezve POLylactic acid ine humwe huremu hwemamorekuru yakagadziriswa nemakemikari synthesis.Iine biodegradability yakanaka.Mushure mekushandiswa, inogona kuderedzwa zvachose nehutachiona muzvisikwa pasi pemamiriro ezvinhu chaiwo, uye pakupedzisira inogadzira carbon dioxide nemvura.Haisi kusvibisa zvakatipoteredza, iyo inobatsira zvikuru kuchengetedzwa kwezvakatipoteredza uye inozivikanwa sezvinhu zvakatipoteredza.China PP Nonwoven Fabric Price
PLA,zvakare zvakafanana nerumwe rudzi rwePET spunbond,ine yakanakisa drapability, kutsvedzerera, kunyudza kunyura uye kupenya kwemhepo, bhakitirostasis yechisikigo uye ganda rinosimbisa isina kusimba asidhi, yakanaka kupisa kupisa uye UV kuramba.
PLA zvese zvakanyorwa se :polylactic acid
Polylactic acid, inozivikanwawo sepolylactide, ndeyemhuri yepolyester.Polylactic acid (PLA) ipolymer inowanikwa nekupolymerization yelactic acid seyakanyanya mbishi zvinhu.The raw material sosi yakakwana uye inogona kushandiswazve.Inonyanya kushandisa chibage uye mufarinya sezviyo.Iyo yekugadzira maitiro ePLA haina kusvibiswa-isina, uye chigadzirwa chinogona kuvandudzwa kuti chione kutenderera muzvisikwa, saka yakanakira girinhi polymer zvinhu.
Polylactic asidhi ine kugadzikana kwakanaka kwekupisa, kupisa tembiricha 170 ~ 230 ℃, yakanaka yekunyungudutsa, inogona kugadzirwa nenzira dzakasiyana siyana, senge extrusion, kuruka, biaxial kutambanudza, jekiseni kuvhuvhuta.Zvigadzirwa zvakagadzirwa nepolylactic asidhi hazvisi biodegradable chete, asiwo zvine biocompatibility yakanaka, gloss, pachena, kunzwa uye kupisa kuramba.Vanewo mamwe mabhakitiriya kuramba, murazvo retardant uye UV kuramba, saka ivo vanoshandiswa zvakanyanya semidziyo yekurongedza, fiber uye nonwovens, etc. Parizvino, inonyanya kushandiswa mukupfeka (yemukati, outerwear), indasitiri (kuvaka, kurima, masango. , kugadzira mapepa) uye minda yezvokurapa nehutano.
