Tinowanzo shandisa "plastiki" kurondedzera manzwiro enhema, zvichida nokuti tinofunga kuti yakachipa, iri nyore kushandisa uye inounza kusvibiswa.Asi iwe unogona kunge usingazivi kuti kune rudzi rwepurasitiki ine recycling rate inopfuura 90% muChina.Mapurasitiki akadzokororwa uye akadzokororwa ari kuramba achishandiswa munzvimbo dzakasiyana siyana.
Mirira, nei plastiki?
Plastiki "yekunyepedzera" chigadzirwa chekugadzirwa kwemaindasitiri.Iyo yakachipa uye ine kuita kwakanaka.
Maererano neshumo ye2019, mutengo wezvinhu patani yemabhodhoro ezvinwiwa akagadzirwa neNo. zvekukwanisa kufanana.
Kugadziriswa kwepurasitiki kunowanikwa sei?
Muna 2019, China yakadzokorodza matani 18.9 miriyoni emapurasitiki emarara, aine kukosha kwekudzokorodza kunodarika mabhiriyoni zana eyuan.Dai ese akagadzirwa kuita mabhodhoro emvura yemamineral, aikwanisa kubata marita emvura anosvika 945 bhiriyoni.Kana munhu wese akanwa marita maviri pazuva, zvaizokwana kuti vanhu veShangai vanwe kwemakore makumi mashanu.
Kuti tinzwisise mamiriro epurasitiki, tinofanira kutanga nekugadzirwa kwayo.
Plastiki inobva kusimba rezvicherwa zvakaita seoiri uye gasi rechisikigo.Isu tinobvisa ma hydrocarbons akadai se liquefied petroleum gasi uye naphtha, uye kuburikidza neakanyanya-tembiricha kupwanya maitiro, "kupwanya" macheni avo marefu mamorekuru kuita mapfupi mamorekuru zvimiro, kureva, ethylene, propylene, butylene, nezvimwe.
Ivo vanonziwo "monomers".Nekupolymerizing akatevedzana ethylene monomers mu polyethylene, tinowana chirongo chemukaka;nekutsiva chikamu chehydrogen neklorini, tinowana PVC resin, iyo yakaoma uye inogona kushandiswa semvura uye gasi pombi.
Plastiki ine dhizaini yakadaro inopfava kana ichipisa uye inogona kuumbwa zvakare.
Zvakanaka, mabhodhoro ezvinwiwa akashandiswa anogona kupfaviswa uye kuumbwazve kuita mabhodhoro ezvinwiwa matsva.Asi chokwadi hachisi nyore kudaro.
Plastiki inosvibiswa nyore nyore panguva yekushandisa uye kuunganidza.Uyezve, mapurasitiki akasiyana ane mapoinzi ekunyunguduka akasiyana, uye kusanganisa zvisina tsarukano kunotungamira mukudzikira kwemhando.
Chinogadzirisa matambudziko aya inyanzvi yemazuva ano yekuronga nekuchenesa.
Mushure mokunge mapurasitiki emarara munyika yedu aunganidzwa, akaputsika uye akacheneswa, anofanira kusarudzwa.Tora optical kurongedza semuenzaniso.Kana mavhenekeri ekutsvaga uye ma sensors achisiyanisa mapurasitiki emavara akasiyana, anotumira masaini kuti avasundire kunze uye abvise.
Mushure mekurongedza, purasitiki inogona kupinda mune yakanyanya kucheneswa maitiro uye kupfuura nepavacuum kana yekupindura mukamuri yakazadzwa neinert gasi.Pakupisa kwepamusoro kunosvika 220 ° C, tsvina mupurasitiki inogona kupararira pamusoro pepurasitiki uye kusvunurwa.
Plastic recycling inogona kutoitwa zvakachena uye zvisina njodzi.
Kunyanya, PET mabhodhoro epurasitiki, ayo ari nyore kuunganidza uye kuchenesa, ave imwe yemhando dzepurasitiki dzine huwandu hwepamusoro hwekudzokorodza.
Pamusoro pekuvhara-loop recycling, PET yakadzokororwa inogona zvakare kushandiswa muzai uye michero yekurongedza mabhokisi, pamwe nezvinodiwa zvezuva nezuva senge machira emubhedha, zvipfeko, mabhokisi ekuchengetera, uye zvekunyora.
Pakati pavo, B2P mapeni emabhodhoro kubva kuBEGREEN akatevedzana anosanganisirwa.B2P inoreva bhodhoro kune peni.Chimiro cheyekutevedzera bhodhoro remvura yemaminerari inoratidza "kwakabva": yakadzokororwa PET plastiki inogona zvakare kupa kukosha munzvimbo chaiyo.
Kufanana nePET bhodhoro zvinyoreso, iyo BEGREEN yakatevedzana zvigadzirwa zvese zvinogadzirwa kubva kupurasitiki yakadzokororwa.Iyi BX-GR5 diki peni yakasvibira yakagadzirwa ne100% yakadzokororwa epurasitiki zvinhu.Muviri wepeni wakagadzirwa nePC resin yakadzokororwa uye chinyoreso chivharo chinogadzirwa neyakadzokororwa PP resin.
Iyo inotsiviwa yemukati musimboti inowedzerawo hupenyu hwesevhisi yepurasitiki uye inobatsira kuderedza marara epurasitiki.
Chinyoreso chayo chine migero mitatu yekutsigira bhora repeni, zvichiita kuti pave nenzvimbo diki yekukwenya uye kunyora kwakapfava nebhora repeni.
Senyanzvi yekugadzira peni, Baile haangounza chete ruzivo rwekunyora zviri nani, asi zvakare anobvumira marara epurasitiki kuti ashumire vanyori nenzira yakachena uye yakachengeteka.
Indasitiri yepurasitiki yakadzokororwa ichiri kutarisana nematambudziko nekuda kwemaitiro akaomarara ekugadzira: mitengo yekugadzira yakatokwira kupfuura mapurasitiki emhandara, uye kutenderera kwekugadzira zvakare.Zvigadzirwa zveBaile's B2P zvinowanzobuda muchitoro nechikonzero ichi.
Nekudaro, kugadzira epurasitiki yakadzokororwa kunoguma nekushomeka kwesimba rekushandisa uye kabhoni emissions kupfuura mhandara yepurasitiki.
Kukosha kwekushandisa purasitiki yakadzokororwa kuzvinhu zvipenyu nemhoteredzo yepasi kwakapfuura zvikuru izvo zvingayerwa nemari.
