Intshayelelo
Iplastiki ehlaziyiweyo ibhekisa kuhlobo lweplastiki enokuthi ihlangabezane neemfuno zokusetyenziswa, ukusebenza kuhlala kungatshintshi ngexesha lolondolozo, kwaye kungancitshiswa kwimicimbi yendalo esingqongileyo emva kokusetyenziswa. Ke ngoko, ikwabizwa ngokuba yiplastiki edityisiweyo yendalo.
Kukho iintlobo ngeentlobo zeplasitiki ezintsha: iplasitiki yefoto, ifoto / i-oxidation / i-oxics / i-biodegraday / ye-bibon diogides esekwe kwiplasitiki, i-thermoplastic stanch upestics.
Ukonakaliswa kwePolymer kubhekisa kwinkqubo yokwaphula i-macromoralecular chain ye-polymerizazazation ebangelwa yimicimbi yemichiza. Inkqubo yokonakaliswa apho iipolimers zichaphazeleka kwiimeko zokusingqongileyo ezinje ngeoksijini, amanzi, imichiza, amandla okungcolisa, kunye nezinye izilwanyana, kunye nezinye izilwanyana ezibizwa ngokuba yi-Degradiyation yezendalo. Ukonakaliswa kunciphisa ubunzima be-molesmer kwaye kunciphisa iipropathi zomzimba zezinto ze-polymer de i-polymer yezinto zaphulukana ne-polymer yezinto ezikhoyo.
Ukonakaliswa kwabadala kwee-polymers kunxulumene ngokuthe ngqo nokuzinza kweepolimers. Ukonakaliswa kokukhula kwe-polymers kunciphisa ubomi benkonzo yePlastiki.
Ukusukela ekufumaneni iiplasitiki, izazinzulu ziye zazibophelela ekuchazeni izinto ezinjalo, oko kukuthi, ukufundwa kwezixhobo, kwaye izaziswa kwiindawo ezahlukeneyo zePolymer nazo zisebenzisa indlela yokuziphatha ekhathazayo yokuphuhlisa iplasitiki yobuqhetseba.
Ezona ndawo ziphambili zeplani ezihlawulelwayo zezi: Ifilimu ye-mul sul, iintlobo ngeengxowa zeplastiki, iingxowa zenkunkuma, iingxowa zenkunkuma, iimpahla zokuthenga ezithengisa ukutya.
Umxholo wokuphelisa
Inkqubo yokonakaliswa kweplagi yendalo ibandakanya ubukhulu becala i-biodegrades, indlela yokuposa kunye nokupheliswa kwemichiza, kwaye ezi nkqubo zithathu eziphambili zezona ziphambili zinemiphumo. Umzekelo, ukuthobeka kwefoto kunye ne-oxide uqhubeka ngaxeshanye kwaye nokukhuthazana; I-biodegradition inokwenzeka ukuba yenzeke emva kwenkqubo yokwenziwa kwefoto.
Imeko yexesha elizayo
Ibango leplastiki elihlawulwayo kulindeleke ukuba liye landa rhoqo, kwaye ngokuthe ngcembe lithathe indawo yeplastikhi yemveli eyenziwe ngeplastikhi.
Zimbini izizathu eziphambili ezinokubangelwa koku, 1) Ukwazisa esidlangalaleni ngokukhuselekileyo kukhuseleko lwendalo kukhuthaza abantu abaninzi abaziqhelanayo kwimveliso ye-eco-gest. 2) Ukuphuculwa kwetekhnoloji ukwehlisa iindleko zemveliso yeemveliso zeplastiki ezinokutsha. Nangona kunjalo, iindleko eziphezulu zokuncitshiswa kwentsholongwane kunye nendawo yokuhlala eqinileyo yemakethi yazo yiplastiki ezahlukeneyo esele zikhona zenza ukuba kube nzima kwi-biodegraphid enokungena kwintengiso. Ke ngoko, iplastiki ye-biodedgradi enokusetyenziswa iplastiki yemveli kwi-tun emfutshane.
Iphepha elichazayo: Yonke idatha kunye nolwazi olufunyenwe kwimveliso ye-ECOOROROORORORK. Ayifanele ithathelwe ingqalelo njengengcaciso ebophelelayo. Ukumiselwa kokufaneleka kolu lwazi kwalo naluphi na usetyenziso oluthile luxanduva lomsebenzisi. Ngaphambi kokusebenza nazo naziphi na izinto, abasebenzisi kufuneka banxibelelane nabathengisi, iarhente karhulumente, okanye iarhente yokuqinisekisa ukwenzela ukufumana ulwazi oluthile, olupheleleyo noluneenkcukacha malunga nezinto abazijongayo. Inxalenye yedatha kunye nolwazi zifakiwe ngokusekwe kuncwadi lwentengiso olunikezwe ngabathengisi bePolymer kunye namanye amalungu avela kuvavanyo lweengcali zethu.
