PE uye PLA yakavharwa mapepa makapu maviri akajairwa mapepa emukombe zvinhu pamusika parizvino.Ivo vane misiyano yakakura maererano nekuchengetedzwa kwezvakatipoteredza, kudzokorodza uye kusimba.Ichi chinyorwa chichapatsanurwa kuita ndima nhanhatu kukurukura maitiro uye misiyano yemhando mbiri idzi dzekapu dzemapepa kuratidza maitiro avo pakuchengetedzeka kwezvakatipoteredza.
PE (polyethylene) uye PLA (polylactic acid) yakavharwa mapepa makapu zvinhu zviviri zvakajairika zvekapu yemapepa.PE yakavharwa mapepa makapu akagadzirwa echinyakare epurasitiki PE, nepo PLA yakavharwa mapepa makapu akagadzirwa neanovandudzwa chirimwa zvinhu PLA.Ichi chinyorwa chine chinangwa chekuenzanisa misiyano yekuchengetedzwa kwezvakatipoteredza, kudzokorodza uye kusimba pakati pemhando mbiri idzi dzemapepa makapukubatsira vanhu kuita sarudzo dziri nani pakushandisa makapu emapepa.
1. Kuenzanisa kwekuchengetedzwa kwezvakatipoteredza.Panyaya yekuchengetedzwa kwezvakatipoteredza, PLA yakavharwa mapepa makapu ari nani.PLA, se bioplastic, inogadzirwa kubva kuchirimwa zvigadzirwa.Mukuenzanisa, PE yakavharwa mapepa makapu inoda zviwanikwa zvepetroleum seyakagadzirwa, iyo ine simba rakakura pane zvakatipoteredza.Kushandisa PLA yakavharidzirwa mapepa makapu kunobatsira kuderedza kuvimba nefossil simba uye kuchengetedza nharaunda.
Kuenzanisa maererano nekugadzirisa zvakare.Panyaya yekugadziriswazve,PLA yakavharwa mapepa makapuzvakare zviri nani pane PE yakavharwa mapepa makapu.Sezvo PLA chiri chinhu chinoodza, PLA mapepa emakapu anogona kudzokororwa uye kudzokororwa mumakapu matsva ePLA mapepa kana zvimwe zvigadzirwa zvebioplastic.PE yakavharwa mapepa makapu inofanirwa kupfuura nehunyanzvi hwekuronga nekuchenesa maitiro asati ashandiswa zvakare.Naizvozvo, PLA yakavharwa mapepa makapu ari nyore kudzoreredza uye kushandisa zvakare, zvinoenderana nepfungwa yehupfumi hwedenderedzwa.
3. Kuenzanisa maererano nekugadzikana.Kana zvasvika pakusimba, PLA yakavharwa mapepa makapu zvakare ane ruoko rwepamusoro.Iyo yekugadzira nzira yePLA inoshandisa zviwanikwa zvinogoneka, senge cornstarch uye zvimwe zvirimwa zvezvirimwa, saka ine zvishoma zvinokanganisa zvakatipoteredza.Kugadzirwa kwePE kunotsamira pazviwanikwa zvepetroleum zvishoma, izvo zvinoisa kudzvanyirira kukuru kune zvakatipoteredza.Mukuwedzera, PLA yakavharidzirwa mapepa makapu inogona kuderera mumvura uye carbon dioxide, zvichiita kuti kusvibiswa kushoma kune ivhu uye miviri yemvura, uye inogadzikana.
Mafungiro ane chekuita nekushandiswa chaiko.Kubva pamaonero ekushandiswa chaiko, kune zvakare mimwe misiyano pakati pePE yakavharwa mapepa makapu uye PLA yakavharwa mapepa emakapu.PE yakavharwa mapepa makapukuve nekudzivirirwa kwakanaka kwekupisa uye kudzivirira kutonhora uye kwakakodzera kurongedza zvinwiwa zvinopisa uye zvinotonhora.Nekudaro, zvinhu zvePLA zvinonyanya kutarisisa tembiricha uye hazvina kukodzera kuchengetedza zvakanyanya-tembiricha zvinwiwa, izvo zvinogona kuita kuti kapu ipfave nekuremara.Naizvozvo, kushandiswa chaiko kunoda kutariswa pakusarudza makapu emapepa.
Kupfupisa, pane misiyano iri pachena pakati pePE yakavharwa mapepa makapu uye PLA yakavharwa mapepa makapu maererano nekuchengetedzwa kwezvakatipoteredza, kudzoreredza uye kusimba.PLA yakavharwa mapepa makapu ane zvirinani kuchengetedzwa kwezvakatipoteredza,recyclability uye kusimba, uye pari zvino inzira inokurudzirwa zvikuru ine ushamwari kwezvakatipoteredza.Kunyangwe tembiricha yekudzivirira kwePLA yakavharwa mapepa makapu haina kunaka senge yePE yakavharwa mapepa emakapu, zvakanakira zvaro zvinodarika zvipingamupinyi.Tinofanira kukurudzira vanhu kuti vashandise PLA yakavharidzirwa mapepa emakapu kusimudzira budiriro inoenderera.Paunosarudza makapu emapepa, kufunga kwakazara kunofanira kuitwa zvichienderana nezvinodiwa chaizvo, uye kushandiswa kweeco-inoshamwaridzika uye yakagadzikana mapepa makapuinofanira kutsigirwa zvakasimba.Nekushanda pamwe chete, tinokwanisa kuita kuti kapu yepepa ishandise zvine hushamwari kwezvakatipoteredza, zvigadziriswe zvakare uye zvirambe zviripo.
