Izithako zeplastiki zidlala indima ebalulekile ekuthuthukiseni izakhiwo nokusebenza kwezinto ze-polymer, zenza kube nokwanelisa izidingo ezihlukahlukene zezimboni. Phakathi kwezithako lezi, izithako zokwenza kube lula zibalulekile ekuthuthukiseni ukuhamba, ukuqina, nokusebenza kwezinto zeplastiki. Njengoba ukukhathazeka ngempilo yomhlaba kukhula kanye nemithetho eqinile emhlabeni jikelele, ukuhlala kwezi thako zeplastiki sekubaluleke kakhulu. Izithako zokwenza kube lula ezihlala zihlala zinciphisa umthelela emvelweni, zisekela imizamo ye-circular economy, futhi ziqinisekisa ukuhambisana nezinhlinzeko ezivela ezinqubweni ezivela ezifana nezindleko ze-carbon e-European Union. Njengomholi ophambili,Shandong Changxing Plastic Additives Co., Ltd uzinikele ekuthuthukiseni ama-plasticizers ahlanzekile anikeza umthelela ezinsizakalweni eziphilayo, ikakhulukazi ekukhiqizeni i-PET.

Izithako zokwenza ipulasitiki ziwumkhiqizo owengeziwe kuma-polymers ukuze zandise ukuhamba kwazo, ukusebenza, nokwandiswa ngokunciphisa amandla phakathi kwemolekyuli. Zibalulekile emikhiqizweni ehlukahlukene ukusuka kumafilimu okupakisha anokuguquguquka nezinsiza zezokwelapha kuya ezicini zezimoto nezinto zokwakha. Izithako zokwenza ipulasitiki ezivame kakhulu ziyi-phthalates, kodwa ukukhathazeka ngempilo yazo nemiphumela emvelweni kuqhubele phambili ucwaningo ngezindlela ezihlukile. Izithako zokwenza ipulasitiki ze-PET (polyethylene terephthalate) zibaluleke kakhulu, njengoba i-PET isetshenziswa kabanzi ezitsha, emathanjeni, nasekupakisheni kokudla. Izithako zokwenza ipulasitiki ezisimeme zithuthukisa ukujikeleza nokusebenza kwe-PET, zenza kube nokukhiqizwa kwezinto eziluhlaza ezihlangabezana nezidingo zemakethe.

Izingxenye ezifana nokupakisha, ezimoto, ezokwakha, nezimpahla zisebenzisa ama-plasticizers ngokuthuthukisa izici zezinto ezizoba nzima noma ezingaqinile. Ngokusebenzisa i-plasticizer efanele, abakhiqizi bangakwazi ukuhlela ukujikeleza, ukujula, nokumelana kwemikhiqizo yabo. Le miphumela ibenze ama-plasticizers abe yinto ebalulekile kwesayensi yezinto zanamuhla nasezinhlelweni zezimboni.

Izinto zokwenziwa zendabuko, ikakhulukazi lezo ezisekelwe ku-phthalate, zikhuphule ukukhathazeka okukhulu kwezempilo kanye nemvelo. Ucwaningo luhlanganise ezinye zephthalates nokuphazamiseka kwe-endocrine, ubuthi bokuzala, nezinye iziphumo ezimbi zempilo. Njengomphumela, amazwe amaningi abeke imithetho eqinile evimbela noma ethululela phansi ezinye zephthalates emikhiqizweni yokusetshenziswa, ikakhulukazi lezo ezithintana nokudla noma ezisetshenziswa ezimpahleni zezingane. Lezi zixhaxha zemithetho zidalile izinselelo kubakhiqizi abathembela ezindleleni zokwenziwa ezijwayelekile.

Ngaphezu kwalokho, imithwalo ye-carbon kanye nezintela zemvelo, ikakhulukazi e-European Union, ithinta ukuncintisana kwezinto zeplastiki ezine-carbon footprint ephezulu. Abakhiqizi manje kumele bacabangele imiphumela yemvelo nezomthetho yezengezo zabo uma bejolisa emakethe yokuthekelisa. Lokhu kukhuphule isidingo sokusebenzisa ama-plasticizers ahlanzekile, angalimazi, ahambisana nezindinganiso zokuphepha zomhlaba futhi asize ekwehliseni ukukhishwa kwe-carbon okuhlobene nokukhiqizwa kweplastiki.

Njengomphumela walezi zinkinga, Shandong Changxing Plastic Additives Co., Ltd uqale ukuthuthukiswa kwezithako zeplastiki eziluhlaza, eziphindaphindwayo eziklanyelwe ngokukhethekile ukukhiqiza i-PET usebenzisa izinto zokwakha ezihlala zikhona neziphindaphindiwe. Izithako zabo zeplastiki ezihlanzekile zihlanganisa ukusebenza okuhle kakhulu nokuziphatha kwemvelo, kunciphisa kakhulu umthelela wekhabhoni emikhiqizweni yeplastiki.

Lezi zithako zeplastiki ezisunguliwe zinikeza ukuhambisana okuhle kakhulu ne-PET, kuthuthukisa ukujula nokusebenza ngaphandle kokwephula ukuphindaphindwa noma ukuphepha. Ngokusebenzisa izinto zok feedstock eziphindaphindiwe nezindlela zokwakha ezithuthukisiwe, imikhiqizo yeShandong Changxing ifaka isandla emnothweni weplastiki ophindaphindwayo futhi isiza abakhiqizi ukuhlangabezana nezidingo ze-EU zokukhokha ikhabhoni, inikeza inzuzo enkulu yokuncintisana kumakhasimende athumela eYurophu.

I-plasticizers ezinzile zeShandong Changxing zinikeza izinzuzo eziningi ezihlelwe kahle kubakhiqizi be-PET abafuna izinketho eziluhlaza. Izithasiselo zazo zithuthukisa ukujikeleza kwemathiriyeli, ukuqina, nokucaca, okuyizici ezibalulekile zemikhiqizo ye-PET ephezulu esetshenziselwa ukupakisha nasezindwangu. Ngaphezu kwalokho, lezi ziplasticizers zenza kube lula ukusebenza, kunciphisa ukusetshenziswa kwamandla nezinsalela ngesikhathi sokukhiqiza.

Omunye wemikhawulo ebalulekile wukunciphisa umthelela we-carbon footprint, okuphendula ngqo ezinselele ezibangelwa yizintela ze-carbon ze-EU. Ngokwehlisa i-carbon efakwe ekukhiqizeni i-PET, izinkampani zingagwema izintela ezinkulu futhi zithuthukise iziqu zabo zemvelo emakethe yomhlaba. Ngaphezu kwalokho, lezi zithasiselo zenzelwe ukuhlangabezana nezindinganiso eziqinile zokuphepha nezemvelo, zinikeza ukuthula kwengqondo kubakhiqizi nakubathengi bokugcina.

Ukuqinisekisa ukuphepha komkhiqizo nokuhambisana nemithetho kuyisisekelo sokusebenza kweShandong Changxing. Ama-plasticizers abo avumelana nemvelo aphumelele ukuhlolwa okuqinile ukuze ahlangabezane nezindinganiso zamazwe omhlaba kuhlanganise ne-REACH (Ukubhaliswa, Ukuhlola, Ukuvunywa, nokukhawulelwa kweKemikhali) kanye ne-RoHS (Ukukhawulelwa kweZinto Ezibulalayo). Lezi ziqinisekiso ziqinisekisa ukungabi khona kwezinto eziyingozi futhi ziqinisekisa ukufaneleka kwemikhiqizo ezinhlelweni ezithintekayo ezifana nokupakishwa kokudla nezinsiza zokwelapha.

Inkampani iphinde ibambelele ezinhlelweni zokuphathwa kwekhwalithi ye-ISO, iqinisekisa ikhwalithi yomkhiqizo ehambisanayo nokulandela. Ngokuhambisana nokuthuthukiswa kwemikhiqizo yabo nemithetho yomhlaba wonke yokuvikela imvelo nokuphepha, iShandong Changxing iqinisekisa ukuthi amakhasimende athola izengezo ezingathuthukisi kuphela ukusebenza komkhiqizo kodwa futhi zisekela izinqubo zokukhiqiza ezisimeme nezinesibopho.

Kubathengi nakwabakhi, ukukhetha ama-plasticizers nezengezo eziqinisekisiwe kuyisinyathelo esibalulekile sokunciphisa umthelela emvelweni. Uma ukhetha imikhiqizo yeplastiki, bheka lezo ezibhalwe ngokuqinisekiswa okuqinisekisa ukusetshenziswa kwezengezo ezihambisana nemvelo nokuhambisana nezindinganiso zokuphepha. Ukuqonda umthombo nokwakheka kwezengezo kusiza ukuqinisekisa ukuthi imikhiqizo iphephile kubantu nasemvelweni.

Abathengi bangase futhi basekele izinkampani ezibophezele ekugcineni imvelo ngokukhetha imikhiqizo ethandwa yokuhlola imikhiqizo ye-green chemistry nezinto eziphinde zisetshenziswe. Ngokukhulisa isidingo sezinto zeplastiki eziphephile, ezihlala isikhathi eside, imakethe izoqhubeka nokwakha nokuthuthukisa umthelela jikelele wokuphila kwemikhiqizo yeplastiki. Kubantu beshishini abafuna ukufunda kabanzi ngama-additives ahlanzekile, ukuvakashela ku-Imikhiqizo ikhasi kunikeza ulwazi olunembile ngezixazululo ezitholakalayo ezihambisana nemvelo.

Ukushintsha kuya kumaplastiki ahlanzekile kubalulekile ikusasa lombono wezinto zokwakha. Izithako ezilungele imvelo zithuthukisa ukusebenza komkhiqizo ngenkathi zinciphisa izingozi zemvelo nezempilo, zisekela imigomo ye-circular economy, futhi ziqinisekisa ukuhambisana nemithetho ethuthukayo efana ne-tariff ye-carbon ye-EU. Njengomholi kulesi sikhala, iShandong Changxing Plastic Additives Co., Ltd ibonisa ukuthi kanjani ubuchwepheshe obusha nokuziphatha kahle kwemvelo kungahlangana ukuze kuhanjiswe ama-plasticizers aphezulu ahlangabezana nezidingo zanamuhla.

Ukukhetha ama-plasticizers ahlanzekile akuthinti kuphela abakhiqizi nabathengi kodwa futhi kunika umhlaba impilo engcono. Ukwamukela lezi zinguquko kuyisinqumo esibalulekile seshishini futhi kuyisinyathelo esibalulekile sokugcina imvelo emhlabeni jikelele kwezobuchwepheshe bezinto.

Ukuze uthole imininingwane enembile kanye nezincazelo zomkhiqizo, ochwepheshe bezimboni bencitshwa ukuba bahlolisise inkampani yeIzindaba isigaba, esiqukethe izifundo zamacala nezibuyekezo ngezinto ezintsha zakamuva. Ukuze uxhumane ne-Shandong Changxing ukuze uthole imibuzo noma ukwesekwa kwezobuchwepheshe, vakashela kuXhumana Nathi ikhasi. Lezi zinsiza zinikeza ulwazi olubalulekile kumabhizinisi afuna ukuguqula abe nezithako zeplastiki ezihlanzekile.
