Sihlala sibabona abantu bephinda besenza iibhotile zeplastiki, kodwa ngaba uyazi ukuba ziyaphi ezi bhotile zeplastiki zisetyenzisiweyo?Ngapha koko, uninzi lweemveliso zeplastiki zinokuphinda zisetyenziswe, kwaye ngothotho lweendlela, iplastiki ingaphinda isetyenziswe kwaye iguqulwe ibezimveliso zeplastiki ezintsha okanye ezinye izinto.Ke kwenzeka ntoni kwezi plastiki zisetyenzisiweyo?Ekugqibeleni, iplastiki iya kubuyela ngayiphi indlela ebomini bethu?Kolu shicilelo sithetha malunga nokuphinda kusetyenziswe iplastiki.
Xa isixa esikhulu seplastiki sithuthwa kuzo zonke iimbombo zoluntu ukuya kwisityalo sokuphinda sisetyenziswe, into yokuqala ekufuneka idlule kuyo kukukhupha uluhlu lwezinto ezingenanto yakwenza neplastiki, njengeelebhile, izivalo, njl. , uze uwahlele ngokohlobo nombala, uze emva koko uwahlele Wahlukane abe ngamasuntswana alingana neengqalutye.Kweli nyathelo, ukusetyenzwa kwasekuqaleni kweeplastiki kugqityiwe, kwaye inyathelo elilandelayo yindlela yokucubungula ezi plastiki.
Eyona ndlela ixhaphakileyo ilula kakhulu, kukunyibilikisa iplastiki kwiqondo lobushushu eliphezulu kwaye uyilungise kwakhona kwezinye iimveliso.Iingenelo zale ndlela kukulula, isantya, kunye neendleko eziphantsi.Ingxaki kuphela kukuba iplastiki kufuneka ihlelwe ngononophelo kwaye yenziwe ngokutsha ngale ndlela.Ukusebenza kweplastiki kuya kuhla kakhulu.Nangona kunjalo, le ndlela ifanelekile kwiiplastiki eziqhelekileyo, ezifana neebhotile zethu zesiselo semihla ngemihla kunye nezinye iibhotile zeplastiki, ezihlaziywa ngokutsha kwaye zisetyenziswe kwakhona ngale ndlela.
Ngoko ngaba kukho nayiphi na indlela yokurisayikilisha engayi kuchaphazela ukusebenza?Ewe kukho, oko kukuthi, iiplastiki zahlulwa zibe ziiyunithi zazo zemichiza yoqobo, njenge-monomers, i-hydrocarbons, njl., kwaye emva koko zidityaniswe kwiiplastiki ezintsha okanye ezinye iikhemikhali.Le ndlela ikrwada kakhulu kwaye inokuphatha iiplastiki ezixubeneyo okanye ezingcolisekileyo, zandise umda wesicelo seeplastiki, kwaye zandise ixabiso elongezelelweyo leeplastiki.Ngokomzekelo, imicu yeplastiki iveliswa ngolu hlobo.Nangona kunjalo, ukusetyenzwa kwakhona kweekhemikhali kufuna ukusetyenziswa kwamandla aphezulu kunye notyalo-mali olukhulu, okuthetha ukuba kuyabiza.
Ngapha koko, ukongeza ekusetyenzisweni ngokutsha kunye nokuveliswa kwakhona kwiiplastiki, kukwakho ukutshiswa ngokuthe ngqo kweeplastiki endaweni yepetroli, kwaye emva koko kusetyenziswa ubushushu obuveliswa ngokutshisa ukuveliswa kombane okanye ezinye izicelo.Le ndlela yokurisayikilishwa iphantse ingabi nandleko, kodwa ingxaki kukuba iza kuvelisa iigesi eziyingozi kwaye ingcolise indalo esingqongileyo.Le ndlela yokurisayikilisha ayisayi kuqwalaselwa ngaphandle kokuba iyimfuneko ngokupheleleyo.Kuphela ziiplastiki ezingenako ukuphinda zisetyenziswe ngoomatshini okanye ngokwekhemikhali okanye ezingenamfuno yokuthengisa eziya kusetyenziswa ngolu hlobo.dibana ne.
Eyona nto ikhethekileyo yiplastiki ekhethekileyo enokonakala.Le plastiki ayifuni unyango olukhethekileyo emva kokuba isetyenziswe kwakhona.Iyakwazi ukuthotywa ngokuthe ngqo yi-microorganisms kwaye ayiyi kubangela ukungcoliseka kwendalo.EJiangsu Yuesheng Technology Co., Ltd., siye sasebenzisa iminyaka emininzi yamava kuphando lwezixhobo kunye nophuhliso ukuze sikhokele ekuphuhliseni iimveliso ezinogwebu zePLA ezonakeleyo.Sinikezela abathengi ngeenkonzo zokumisa enye ngokusekelwe kwiimfuno zabo ezahlukeneyo kwaye akukho mfuneko yokuba benze utshintsho kwizixhobo zabo ezikhoyo.Ukuba wenza naluphi na utshintsho, ungaziqhelanisa ngokuthe ngqo!
Kukwakho nezinye izisombululo ezizodwa ezizama ukusebenzisa iplastiki ehlaziyiweyo ukwenza ezinye iikhemikhali.Ngokomzekelo, i-carbon black, esetyenziselwa ukwenza irabha, i-inki, ipeyinti kunye nezinye iimveliso, iguqulwa ibe yikhabhoni emnyama kunye nezinye iigesi ngokukrazula inkunkuma yeplastiki.Emva kwayo yonke loo nto, eneneni, ezi mveliso, njengeeplastiki, zinokufumana izinto ezikrwada ngeshishini lepetrochemical, ngoko ke akunzima ukuqonda ukusebenzisana kwazo.
Okona kumangalisa nangakumbi kukuba iplastiki esetyenzisiweyo ingasetyenziselwa ukwenza imethanol.Inkunkuma yeplastiki iguqulwa ibe yimethanol kunye nezinye iigesi ngokuguqulwa kwegesi kunye nokuguqulwa kwe-catalytic.Le ndlela inokunciphisa ukusetyenziswa kwegesi yendalo kunye nokwandisa imveliso kunye nokusebenza kakuhle kwe-methanol.Emva kokufumana i-methanol, sinokusebenzisa i-methanol ukwenza i-formaldehyde, i-ethanol, i-propylene kunye nezinye izinto.
Kakade ke, indlela ethile yokurisayikilisha esetyenziswayo ixhomekeke kuhlobo lweplastiki, njengeplastiki ye-PET, eyi-thermoplastic ecacileyo edla ngokusetyenziswa ukwenza iibhotile zesiselo, izikhongozeli zokutya, njl. njl. .Le nkqubo ingasetyenziswa kumgca we-PET wemveliso ye-Jiangsu Yuesheng Technology Co., Ltd., ebandakanyeka kakhulu kuphando kunye nophuhliso lwe-plastic extruders kunye nezixhobo ezinxulumene nazo.Ngokuveliswa kwamashishini, sinokubonelela ngezisombululo ezipheleleyo zokusetyenzwa kwe-polymer material extrusion.Iyunithi ye-extrusion granulation enamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda iyaqhubeka nokwenza inkqubela kwaye izise abathengi imveliso ekumgangatho ophezulu kunye namava angcono omsebenzisi.
Ukurisayikilishwa kweplastiki kunceda ekunciphiseni ukuxhomekeka kwi-oyile ekrwada, ukonga izixhobo, ukukhusela okusingqongileyo kunye nempilo yabantu, kunye nokunciphisa ukukhutshwa kwegesi yegreenhouse kunye nomonakalo wongcoliseko lweplastiki.Iiplastiki ezilahlwayo esizilahlayo kubomi bethu bemihla ngemihla, ukuba aziphinda zisetyenziswe ngokuphinda zisetyenziswe, ngenye imini ziya kubuyela eluntwini ngezinye iindlela.Ngoko ke, kuthi, into ebaluleke kakhulu kukuhlela kakuhle inkunkuma kwaye uyivumele ihlaziywe.Abo bahambayo, abo bafanele bahlale.Ke ngaba uyazi ukuba wenzeni kwakhona iimveliso zeplastiki?
