RPET, kupfupikiswa kwe recycled polyethylene tetraphyte kunowanzoshandiswa.Isu tichave tichitsanangura PET zvishoma pazasi.Asi ikozvino, ziva kuti PET ndiyo yechina inonyanya kushandiswa kwepurasitiki resin munyika.PET inogona kuwanikwa mune zvese kubva mukupfeka uye kurongedza chikafu.Kana ukaona izwi rekuti "RPET", zvinoreva kuti PET yakashandiswa muchigadzirwa inofanira kunge yakabva kune yakamboshandiswa sosi.
Chii chinonzi polyethylene tetraphyte?
Kuti zvive pachena, plastiki yega yega yawakamboshandisa yakagadzirwa uchishandisa imwe polymer.PVC mabhodhoro emukaka achagadzirwa nechinhu chakasiyana pane PET mabhodhoro emvura.
PET inogadzirwa nemafuta asina kuchena.Zvakatipoteredza zvinokanganiswa zvakanyanya nemaitiro ekubvisa mafuta asina kuchena kubva pasi.Kuti uite PET yakanyungudutswa, unofanirwa kutora doro rinonzi Ethylene glycol uye risanganise ne terephthalic acids.Esterification inoitika kana zvese zvigadzirwa zvakabatanidzwa pamwechete, kugadzira PET, refu-cheni polymer.
Isu tinosarudza mapolymers zvichienderana nekuti chigadzirwa chekupedzisira chichaita sei.PET inonzi thermoplastic.Izvi zvinoreva kuti inogona kukotama nyore kune chimiro chaunoda nekuchipisa, uye ipapo inochengetedza simba rayo kana yatonhora.PET ine huremu huremu, haina chepfu uye yakasimba zvakanyanya.Ichi ndicho chikonzero chiri icho chakasarudzika chekurongedza zvinhu zvechikafu uye chinwiwa indasitiri.
MaPETs anoshandiswa chete kurongedza?
Kwete. Indasitiri yemabhodhoro epurasitiki ndiyo inonyanya kushandisa PET munyika yose pa30%.Zvisinei, izvi handizvo zvoga.Kunyangwe PET ichiwanzo kunzi polyester, zvingangoita kuti zvipfeko zvakawanda muwadhiropu yako zvinogadzirwa kubva kuPET.Iyo mvura haibvumidzwe kuumba kune mudziyo wairi kugadzirwa.Pane kudaro, inopfuudzwa kuburikidza ne spinnerate (inenge musoro wekugeza) uye inoumba tambo refu.Tandi idzi dzinogona kurukwa pamwechete kuita jira rakareruka, rinogara.Polyester ndiyo inonyanya kushandiswa nevanhu faibha muindasitiri yemachira.Polyester iri nyore kugadzira pane donje, uye hainyanyi kukanganiswa nekushanduka kwemitengo nekuda kwemamiriro ekunze.Zvinogoneka kuti chipfeko chauri kupfeka parizvino chine polyester.Polyester inoshandiswa zvakanyanya mukugadzira matende uye mabhandi ekutakura.Polyester inokwanisa kubata chero chinhu chinoda kureruka uye chinogara.
PET yakanaka uye yakaipa mapoinzi
PET ine zvakawanda zvakanaka, kusanganisira kugara uye kuita zvinhu zvakasiyana-siyana pamwe nekuchipa pane dzimwe sarudzo.PET inogona kushandiswazve, semamwe mapurasitiki.MuUK, 3% chete yakashandiswa zvakare kubva kumabhodhoro ePET muna 2001. Nhamba iyoyo yakakwira kusvika ku60% mu2014 nekuda kwevagadziri vezvinwiwa vachichinjira kumabhodhoro ePET pese pazvinogoneka, uye mamwe maitiro ezvekudzokorodza enyika anoita kuti zvive nyore kudzokorora.
PET ine imwe yehutera hwayo hukuru.PET musanganiswa wakasimba zvekuti zvinotora makore 700 kuti uwedzere kuva ivhu.Kunyangwe kudzokorodza kwePET kwakaona kuvandudzwa kwakakosha mumakore gumi apfuura, zvakawanda zvinoda kuitwa.Zvikamu zvakawanda zvepasi zvatove nemakomo akakura semaguta madiki, akazadzwa nePET plastiki chete.Isu tinoenderera mberi nekuwedzera kune aya madhishi zuva rega rega nekuda kwekushandisa kwedu zvakanyanya PET.
PET plastiki isanganiswa yakasimba kwazvo.Zvinotora makore 700 kuti PET plastiki iputswe kana ikazopera mumarara.Kune zvikamu zvepasirese zvine makomo akakura semaguta madiki, asi ese akagadzirwa nePET plastiki.
Saka, seiRPETkugadzirisa dambudziko rekusvibiswa kwepurasitiki munyika yedu?
RPET inotora ipurasitiki yakatogadzirwa (kazhinji mabhodhoro epurasitiki) uye inoipwanya kuita maflakes madiki.Iyo PET iri pakati pebhodhoro rega rega inoparadzaniswa nekunyungudutsa aya maflakes.Iyo PET inogona kushandiswa kugadzira zvese kubva kujuzi kuenda kune mamwe mabhodhoro epurasitiki.Iyi PET ine 50% yakawanda simba-inoshanda pane kugadzira PET kubva kutanga.Pamusoro pezvo, mabhodhoro aripo anogona kushandiswa kugadzira PET, zvinoreva kuti haapere mukurasira.Izvi zvinotibvumira kusiya nyika sezvairi.Panzvimbo pekubvisa chinhu chakakosha kubva mumafuta asina kuchena, ayo anogona kukanganisa zvakanyanya, isu tinoshandisa kuwanda kwechigadzirwa icho chingave chakakonzera zvakananga mukuraswa kwemarara.
