Nekuwedzera kwakawedzera kwesimba rekugadzira renyika yangu polyethylene kumusoro kwepamusoro mabhizinesi ekugadzira mumakore achangopfuura, chikamu chekugovera chakawedzera zvakanyanya.Panguva imwecheteyo, nekuda kwekuenderera mberi kwekuvandudzwa kwekugadzirwa kwevagari uye mararamiro ehupenyu, kudiwa kwavo kwakawedzera zvishoma mumakore apfuura.Nekudaro, kubva muhafu yechipiri ya2021, mamiriro epasi rose anga achinyengera uye achichinja.Kupararira kwedenda uye hondo dzemuno zvakakonzera kusaenzana kwesimba repasi rose-remari.kuparara.Kuwedzera kusava nechokwadi muhupfumi hukuru kwaendesa manzwiro ekudya kwevagari padanho rekuchenjerera.Pasi pemamiriro ezvinhu aripo, njodzi nematambudziko anotarisana nekugadzirwa kwezvigadzirwa zve polyethylene zvakare zvakanyanya.
Kuwanda kwevanhu uye kubudirira kwehupfumi kunogadzirisa kugoverwa kwePE kushandiswa.Kubva pamaonero enzvimbo dzepasi pemvura dzinoshandiswa, East China, South China, uye North China ndidzo nzvimbo dzinoshandiswa zvakanyanya kuzasi kwemvura yepolyethylene munyika yangu, uye icharamba iri iyo mitatu yepamusoro maererano nekushandiswa kwenguva yakareba iri kuuya.Nekudaro, nekuenderera mberi nekuvhurwa kwemidziyo mitsva yekugadzira mune ramangwana, zvinotarisirwa kuti gaka rekushandisa munzvimbo nhatu huru dzekushandisa richadzikiswa kusvika kumwero wakati.Zvinotarisirwa kuti izvi zvichakanganisa zvakanyanya mune ramangwana rekupa uye yekuda maitiro uye chigadzirwa Logistics inoyerera mumatunhu makuru.Zvakakoshawo kutaura kuti kunyangwe chikamu chekudzika kwemvura mudunhu rekumadokero chiri chidiki pane icho cheEast China, South China, neNorth China, chinotungamirwa nemitemo yemumba yakaita se "One Belt, One Road" uye "Western Development", iyo yakadzika kushandiswa kwepolyethylene munharaunda yekumadokero ichawedzera mune ramangwana.Pane tarisiro yekuwedzera, kunyanya yezvigadzirwa zvinodikanwa zvezvivakwa zvinotungamirwa nemapombi, uye kudiwa kwekuumbwa kwejekiseni uye zvigadzirwa zvinotenderera zvinounzwa nekuenderera mberi kwekuvandudzwa kwehupenyu zviri pachena.
Zvino, maererano nemhando dzepasi pemvura dzekushandisa mune ramangwana, rudzii rwetarisiro yebudiriro iyo iyo huru yekudzika kwemvura inoda marudzi e polyethylene?
Parizvino, iyo huru yepasi pemvura inoshandiswa yepolyethylene munyika yangu inosanganisira firimu, jekiseni kuumba, pombi, hollow, waya yekudhirowa, tambo, metallocene, coating uye mamwe marudzi makuru.
Yekutanga kutakura mutoro, chikamu chikuru chepasi pemvura inoshandiswa ifirimu.Kune iyo indasitiri yechigadzirwa chemufirimu, iyo huru ifirimu rekurima, firimu reindasitiri uye firimu rekurongedza chigadzirwa.Nekudaro, mumakore achangopfuura, zvinhu zvakaita sezvirambidzo pamabhegi epurasitiki uye kudzokororwa kuderera kwekuda nekuda kwedenda zvakagara zvichivanetsa, uye vari kutarisana nemamiriro ezvinhu anonyadzisa.Iko kudiwa kwezvigadzirwa zvepurasitiki zvinoraswa zvemafirimu zvichatsiviwa zvishoma nezvishoma nemukurumbira wemapurasitiki anoparara.Vazhinji vagadziri vemafirimu vari kutarisanawo nemaindasitiri ehunyanzvi hwekuvandudza tekinoroji, uye zvishoma nezvishoma vari kusimukira vakananga kumafirimu emaindasitiri anogona kudzokororwa ane simba rakasimba uye kuita.Nekudaro, nekuda kwekuparara kwemafirimu epurasitiki anoshatisa, pane zvinodikanwa zvakasimba zvekurongedza kwekunze, kana kudiwa kwemafirimu ekurongedza ekunze anoda kuchengetwa kwenguva yakareba kupfuura nguva yekuparara, uye mafirimu emaindasitiri nemamwe minda achiri kusagadziriswa, saka zvigadzirwa zvemufirimu zvicharamba zvichishandiswa.Yakave iripo sechigadzirwa chikuru kuzasi kwepolyethylene kwenguva yakareba, asi panogona kunge paine kuderera kwekukura kwekushandisa uye kuderera kwechikamu.
Pamusoro pezvo, maindasitiri akadai semajekiseni ekuumba, mapaipi, uye makomba ane hukama zvakanyanya nekugadzirwa uye hupenyu acharamba ari iwo makuru evatengi zvigadzirwa kuzasi kwepolyethylene mumakore mashoma anotevera, uye acharamba achitongwa nehupfumi, zvinodiwa zuva nezuva, uye veruzhinji. zvishandiso uye midziyo.Hupenyu hwevanhu hwakabatana nezvinhu zvinogara kwenguva refu, uye kudiwa kwekuderedzwa kwechigadzirwa kunodzikiswa.Parizvino, dambudziko guru rakatarisana nemaindasitiri ari pamusoro nderekuti kukura kwechikamu chezvivakwa kwakamira mumakore achangopfuura.Nekuda kwezvinhu zvakaita semhinduro isina kunaka pamanzwiro ekudya kwevagari anounzwa nedenda rinodzokororwa, kusimudzira kweindasitiri yezvigadzirwa kwakatarisana nekumwe kuramba kukura.Nokudaro, kuchinja kwechikamu chenguva pfupi kune zvishoma, uye hazvinyanyi kukanganiswa nezvigadzirwa zvekuora.Indasitiri yepombi inonyanya kukanganiswa nemitemo, nepo jekiseni rekugadzira uye maburi zvigadzirwa zvinonyanya kukanganiswa nemafungiro ekushandiswa kwevagari, uye kukura kunoderera mune ramangwana.mukana.
Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, iyo yega uye kuvandudza kwevanhu kwezvigadzirwa zvepurasitiki, pamwe nekugadzirwa kwemhando yechigadzirwa uye zvinodiwa zvekugadzira zvinogara zvichikura.Naizvozvo, mune ramangwana, indasitiri yezvigadzirwa zvepurasitiki ichawedzera kudiwa kwezvimwe zvigadzirwa zvinovandudza mashandiro ezvigadzirwa zvepurasitiki, senge metallocenes, mapurasitiki anotenderedza, zvekupfeka uye zvimwe zvakakwirira-zvakawedzerwa zvigadzirwa kana zvigadzirwa zvine zvakasiyana zvinodiwa muminda yakakosha. .Pamusoro pezvo, nekuda kwekugadzirwa kwakanyanya kwemabhizinesi ekugadzirwa kwepolyethylene mumakore achangopfuura, zvichikonzera kukanganisa kwakakomba kwechigadzirwa, uye kukakavara pakati peRussia neUkraine mukati megore kwakakonzera mitengo yakakwira yemafuta kukwidza purofiti ye ethylene, uye kuwedzera kwemutengo. uye kugovera kwakaguma mune yakakomba chigadzirwa homogeneity.Pasi pemamiriro ezvinhu aripo, Vagadziri ve polyethylene vari kuwedzera kushingaira mukugadzirwa kwepamusoro-soro-yakawedzerwa zvigadzirwa zvakadai semetallocenes, rotational molding, uye machira, maererano nekuvandudzwa kwemaindastiri ezasi.Naizvozvo, kukura kwezvigadzirwa zvinogona kuwedzera kune imwe nhanho mune ramangwana.
