Nguva pfupi yadarika, mabhegi epurasitiki anogona kuparara ane mukurumbira zvikuru, uye mazinga akasiyana-siyana ekurambidzwa kwepurasitiki akatanga kutenderera pasirese, uye seimwe yemhando huru dzemabhegi epurasitiki anoodza, PLA inongove imwe yezvinonyanya kukosha.Ngatinyatsoteverai nyanzvi yekurongedza mabhegi anogadzira TOP Pack kuti tinzwisise iyo PLA biodegradable epurasitiki mabhegi.
- Chii chinonzi PLA uye chinogadzirwa nei?
PLA ipolymer (polylactic acid) inoumbwa nediki lactic acid zvikamu.Lactic acid is organic acid inoita basa rakakosha muhupenyu hwedu hwezuva nezuva.Iyo yogati yatinowanzo kunwa kana chero chinhu chine glucose chinogona kushandurwa kuita lactic acid, uye iyo lactic acid yePLA inodyiwa inobva kuchibage, yakagadzirwa kubva kune yakasvibirira ye starch yakatorwa kubva chibage.
Parizvino, PLA ndechimwe chezvinhu zvinonyanya kushandiswa mumabhegi epurasitiki anoodza, ane chinhu chakasiyana: PLA chimwe chezvinhu zvisingabvisike zvisina muchetura, zvigadzirwa zvayo kubva kune zvakasikwa.
- Mwero wePLA degradation unoenderana nei?
Iyo biodegradation process uye nguva yayo zvinoenderana zvakanyanya nenharaunda.Semuyenzaniso, kupisa, mwando, uye utachiona Kuviga PLA mabhegi epurasitiki asinganyanyi kuparara mukati mevhu kunogona kukonzera zviratidzo zvekuora mumwedzi mitanhatu.
Uye PLA biodegradable epurasitiki mabhegi anotora nguva yakareba kuti adzikise pakamuri tembiricha uye pasi pekumanikidzwa.Mukamuri yakajairika, PLA biodegradable bhegi repurasitiki kushatisa kuchagara kwenguva yakareba.Chiedza chezuva hachizo mhanyisa biodegradation (kunze kwekupisa), uye mwenje weUV unongokonzera kuti zvinhu zvirasikirwe neruvara uye kuve wakacheneruka, zvinova zvakafanana nemapurasitiki mazhinji.
Zvakanakira kushandisa PLA biodegradable epurasitiki mabhegi
Munhoroondo yevanhu, mabhegi epurasitiki akanyanya nyore uye akanaka kushandisa, zvichiita kuti vanhu vave vasingaparadzanisiki kubva kumabhegi epurasitiki muupenyu hwavo hwezuva nezuva.Izvo zviri nyore zvemabhegi epurasitiki zvinoita kuti vanhu vakanganwe kuti kugadzirwa kwepakutanga kwemabhegi epurasitiki haisi chinhu chinoraswa, chinowanzoshandiswa kamwe chete uye chakaraswa.Asi vanhu vazhinji havazivi kuti chinhu chikuru chekugadzira mabhegi epurasitiki ndeye polyethylene, iyo yakaoma zvikuru kuderedza.Nhamba yakawanda yemabhegi epurasitiki akaraswa anovigwa muvhu, izvo zvinozotungamirira kune nzvimbo huru yenyika nekuda kwekuvigwa kwemapurasitiki uye kushanda kwenguva refu.Uku kusvibiswa kuchena.Kana vanhu vakashandisa mabhegi epurasitiki mabhegi epurasitiki anoora, dambudziko iri rinogadziriswa.PLA ndeimwe yeanowanzo shandiswa biodegradable mapurasitiki uye i polymer yakagadzirwa kubva kulactic acid, inova isiri-kusvibisa uye biodegradable chigadzirwa.Mushure mekushandisa, PLA inogona kuumbwa uye kuderedzwa kuita kabhoni dhaibhorosi uye mvura pane tembiricha inopfuura 55 ° C kana nekuita kweokisijeni-yakapfuma microorganisms kuti iwane kutenderera kwezvinhu mumasikirwo.Kuenzaniswa neiyo yekutanga d yemabhegi epurasitiki akajairwa, mabhegi epurasitiki anoodza anongoda mwedzi mishoma kuti apedze kushatisa kwenguva.Izvi zvinorerutsira kupambadzwa kwezviwanikwa zvevhu kusvika pamwero mukuru uye hazvina kukanganisa kune zvakatipoteredza.Pamusoro pezvo, mabhegi epurasitiki akajairwa mukugadzira anopedza mafuta efossil, nepo mabhegi epurasitiki anoodeka achidzikisa inenge hafu yemafuta efosi kupfuura iwo.Semuyenzaniso, dai zvinhu zvese zvepurasitiki zviri munyika zvakatsiviwa nemabhegi epurasitiki anoodza mukati megore, zvaizochengetedza mabhiriyoni 1.3 emadhiramu emafuta efosi mugore, inova chikamu chekushandiswa kwemafuta epasi rose.Kuipa kwePLA ndiko kushatisa kwemamiriro ezvinhu.Nekudaro, nekuda kwemutengo wakaderera wePLA mune biodegradable plastiki bag zvinhu, kushandiswa kwePLA kuri pamberi.
