Mabhizinesi akawedzera kugadzirwa, mairairo anokonzerwa panguva imwe chete zvakare akakonzera kuwanikwa kwezvinhu zvisina kugadzirwa, kunyanya pbat uye zvimwe zvinosvibisa membrane bag zvinhu mumwedzi mina chete, mutengo wakakurisa. Naizvozvo, iyo pla plath ine mutengo wakasimba wakakwezva kutarisisa.
Poly (lactic acid) (Pla), zvakare anozivikanwa sePoly (Lactide) Ends zvigadzirwa, zvakadai seCO2 uye H2O.
Nekuda kwezvakanakira zvaro zvemitambo yakakwirira simba, kugadzirisa zviri nyore, zvakanyungudika zvekunyungudika, biodergradability uye yakashandiswa zvakanyanya mukurima, kurapa kwekurima, kurapwa kwechikafu, kurapwa uye kumwe kurapwa uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda. Iyo isina kusvibiswa huswa yakagamuchira zvakanyanya kutarisisa mumakore achangopfuura.
Mukupindura kune yepurasitiki yekurambidzwa kuronga, mapepa emapepa anoshandiswa zvakanyanya muChina. Nekudaro, mapepa emapepa anocheneswa zvakanyanya nekuda kwekuremekedza kwavo kusashandiswa. Vazhinji vanogadzira uye vanowedzera vanotanga kusarudza zvinhu zvakagadziridzwa kuti zvigadzire zvigadziko.
Nekudaro, kunyangwe polylactic acid ine zvakanaka michina yezvivakwa, its yakaderera yekukwenenzverwa (kazhinji isingasviki 10%) uye kusimba kusimba kwemasango.
Naizvozvo, plah torating yave musoro wekutsvagisa pamusoro pekutsvagisa parizvino. Izvi zvinotevera kufambira mberi kwazvino kwePlaghHeing kutsvagisa.
Poly - Lactic acid (Pla) ndeimwe yematare akura bioderable mapurasitiki. Zvishidziro zvaro zvinogadzirwa kubva kune inovandudza chirimwa machira, chibage, zvekurima ne-zvigadzirwa, nezvimwe, uye zvine biodegradability. Play ane makaniti akanakisa, akafanana nePolypropylene mapurasitiki, uye anogona kutsiva PP uye mhuka mapurasitiki mune dzimwe minda. Zvichakadaro, Pla ane gloss yakanaka, transpency, ruoko runonzwa uye zvimwe zvinwiwa zvinodhaka
Pla Production Status
Parizvino, Pla ane nzira mbiri dzechiSynthetic. Imwe ndeyekutaura zvakananga Maitiro ekugadzira akareruka uye mutengo wakaderera, asi iyo molecular uremu hwechigadzirwa hachifanani, uye inoshanda application maitiro murombo.
Imwe ndeye lactside mhete - kuvhura polymerization, iyo ndiyo huru yekugadzira maitiro.
Degradability yePla
Pla inogadzikana pamhepo tembiricha, asi inonyudza nyore nyore kuita co2 uye mvura mune zvishoma zvakakwirira tembiricha mamiriro, acid-base nharaunda uye microbial nharaunda. Naizvozvo, izvo zvigadzirwa zvinogona kushandiswa zvakachengeteka mukati menguva yekubvumidzwa uye yakasvibiswa nguva mushure mekuraswa nekudzora nharaunda uye kurongedza.
Zvinhu zvinokanganisa kusarudzika zvinonyanya kusanganisira zvinyoro-nyoro suremu, Crystalline State, microcture tembiricha uye humidity, inovhenekera nguva uye neyakaivhenekera microorganisms.
Pla uye zvimwe zvinhu zvinogona kukanganisa chiyero chinosvibiswa.
Semuenzaniso, pla kuwedzera imwe huwandu hwehuni hwehuni kana chibage fiber zvinogona kukurudzira kwazvo chiyero chekusvibiswa.
Play Barrier Performance
Insulation inoreva kugona kwezvinhu zvekudzivirira iyo ndima yegesi kana mupfu wemvura.
Iyo inovhiringidza pfuma yakakosha kwazvo kune zvekutakura zvinhu. Parizvino, iyo inowanzoitika purasitiki purasitiki bhegi pamusika iri pla / pabat composite zvinyorwa.
Iyo inotambisa zvivakwa zveiyo yakavandudzwa plus yemafirimu inogona kuwedzera munda wekushandisa.
Zvinhu zvinokanganisa plar bar barari zvakanyanya kusanganisira zvinhu zvemukati (molecular chimiro uye crystallation mamiriro) uye zvinhu zvekunze (tembiricha, simba rekunze).
1. Heating Plhafirimu ichaderedza zvivakwa zvaro zvipfukuri, saka Pl haina kukodzera kurongedza chikafu chinoda kupisa.
2.
Kana iyo tensile chiyero ichiwedzerwa kubva pa1 kusvika ku6,5, crystallinity yePl inowedzera kwazvo, saka pfuma inotambisa.
3. Kuwedzera zvimwe zvipingamupinyi (zvakadai sevhu uye fiber) kune iyo pla plac
Izvi zvinodaro nekuti chipingamupinyi chinosimbisa nzira yakacheneswa yemvura kana gasi premeation maitiro emamorekuru madiki.
