I-Dioctyl phthalate (DOP) iyinto esetshenziswa kabanzi yokwengeza ukuze yenze ipulasitiki ithambe, ebaluleke kakhulu ekuthuthukiseni ukuvumelana nezimo, ukuqina, kanye nokuphila isikhathi eside kwezinhlobonhlobo zemikhiqizo yepulasitiki. Njengesengezo sekhwalithi ephezulu, sisiza ekuthambiseni amapulasitiki afana ne-polyvinyl chloride (PVC), sibenze bavumelane kakhudlwana ezinhlelweni ezahlukahlukene ezifana nezokwakha, ezemoto, kanye nezimpahla zabathengi. Ngokungafani nezinye izithako, i-dioctyl phthalate ihlanganisa ukuhambisana okuhle nama-polymers kanye nezinga eliphezulu lokusebenza, okwenza kube ukukhetha okuncanyelwayo kwabakhiqizi emhlabeni wonke. Indima yayo ayigcini nje ekwenzeni ipulasitiki ithambe kodwa futhi ithinta ukuzinza okuphelele komshini namakhemikhali komkhiqizo wokugcina. Ngenxa yokukhathazeka ngemvelo eminyakeni yamuva nje, isidingo sezithako zepulasitiki ezisimeme nezinganakile njenge-dioctyl phthalate siye sande, ikakhulukazi ezimakethe ezinemithetho eqinile njenge-European Union.

I-Shandong Changxing Plastic Additives Co., Ltd. ingumkhiqizi ohamba phambili ochwepheshe ekukhiqizeni i-dioctyl phthalate esezingeni eliphezulu, enikeza izixazululo ezintsha nezinqamuzayo ezihlangabezana namazinga omhlaba. Ubuchwepheshe babo ekukhiqizeni amakhemikhali buqinisekisa ukuthi imikhiqizo ihambisana nemithetho yokuphepha neyemvelo, isekela izimboni ekukhiqizeni upulasitiki oluluhlaza. Ukuzibophezela kwenkampani ezingeni eliphezulu nasekunqamuzeni kubenza babe umlingani omethembayo kumabhizinisi ahlose ukuthuthukisa ukusebenza komkhiqizo ngenkathi kuncishiswa umthelela emvelweni. Lesi sihloko sihluza indima ehlukahlukene ye-dioctyl phthalate, izinzuzo zayo, nokuthi okunikezwa yiShandong Changxing kunomthelela kanjani esikhathini esizayo esinqamuzayo ekukhiqizeni upulasitiki.

Umsebenzi oyinhloko we-dioctyl phthalate ekwenzeni amaplastiki ukuba yi-plasticizer, esebenza ngokuzibeka phakathi kwezintambo ze-polymer. Le nqubo yandisa ukuguquguquka nokusebenza kwamaplastiki ngaphandle kokunciphisa amandla. Ezicelo ezifana nokufakwa kwezintambo, phansi, nesikhumba esenziweyo, i-dioctyl phthalate iqinisekisa ukuthi izinto zihlala zithambile ngaphansi kwezimo ezahlukahlukene. Ngaphezu kwalokho, kusiza ukuthuthukisa izici zokucubungula ngokunciphisa izinga lokushisa lokuguquguquka kwe-polymer, kuthuthukisa ukuzinza kwazo kwe-thermal nokumelana nokuqhekeka. Ngaphandle kwe-plasticizing, i-dioctyl phthalate iphinde ibe negalelo ekuqinisweni nasekuqinisweni kwemikhiqizo yokugcina ngokumelana nokubola okubangelwa izinto zemvelo ezifana nokukhanya kwe-UV nomswakama.

Phakathi komndeni wama-phthalate plasticizers, i-dioctyl phthalate ihlukaniswa ngokusebenza kwayo nokonga. Ivame ukuqhathaniswa ne-dioctyl terephthalate, enye i-plasticizer esetshenziswa ezinhlelweni ezikhethekile, kodwa i-DOP isalokhu ikhethwa kwimikhiqizo ye-plastic ejwayelekile ngenxa yokusebenza kwayo okufakazelwe nokutholakala kwayo. Isidingo somhlaba wonke se-dioctyl phthalate sithonywa ukusebenza kwayo okuhlukahlukene ezimakethe ezahlukahlukene, okubandakanya ukupakisha, ingaphakathi lezimoto, nemishini yezokwelapha. Ngenxa yendima yayo ekwenzeni i-plastic isebenze kakhudlwana futhi iqine, amakhemikhali e-DOP ayadingeka kakhulu ezinhlelweni zokukhiqiza zesimanje. Ulwazi lokusetshenziswa okufanele nokwakheka kwawo luqinisekisa imiphumela efanele futhi lukhulisa izinzuzo kubakhiqizi nabathengi ngokufanayo.

I-Shandong Changxing Plastic Additives Co., Ltd. ihlinzeka ngemikhiqizo ye-dioctyl phthalate ehlukaniswa ngamazinga aphezulu kakhulu okuhlanzeka, ikhwalithi engaguquki, kanye nezici zokusebenza ezithuthukisiwe. Amakhemikhali ayo e-DOP athuthukiswe kusetshenziswa ubuchwepheshe obuthuthukisiwe bokukhiqiza obuqinisekisa ukuba nomoya ophansi kanye nokusebenza okuphezulu kokwenza ipulasitiki. Lokhu kuholela ekuzinzeni okungcono kokucubungula kanye nokuguquguquka okuhlala isikhathi eside emikhiqizweni yepulasitiki eqediwe. Amakhasimende azuza ekuhlinzekeni okuthembekile kanye namazinga okuncintisana entengo ye-dioctyl phthalate, okuthuthukisa ukonga izindleko ngaphandle kokudela ikhwalithi. Ukugxila enkampanini ocwaningo nasekuthuthukisweni kusho futhi ukuthuthukiswa okuqhubekayo kwemikhiqizo nezixazululo ezenzelwe izidingo ezithile zezimboni.

Ngaphezu kwalokho, imikhiqizo yeShandong Changxing yakhelwe ukuthi ihambisane kalula nezinto ezisetshenziswa kabusha, isekela izinhlelo zokukhiqiza eziluhlaza. Lokhu kuhambisana kusiza abakhiqizi ukuthi bakhiqize amapulasitiki esimeme ahlangabezana nezimfuneko zomthetho eziguqukayo kanye nokulindela kwabathengi kwemikhiqizo enobungani nemvelo. Ukuzibophezela kwenkampani ekuqambeni izinto ezintsha kubonakala emizamweni yabo eqhubekayo yokwenza kahle izindlela zokupheka ezinciphisa umthelela omubi emvelweni ngenkathi kugcinwa ukusebenza kahle kwezobuchwepheshe. Ezinkampanini ezifuna abahlinzeki abathembekile bezengezo zamapulasitiki ezisezingeni eliphezulu, iShandong Changxing imele inzuzo yokuncintisana ngokusebenzisa ikhwalithi, ukusimama, kanye nenkonzo egxile kumakhasimende.

Ukuphazamiseka kwemvelo okubangelwa izithako zepulasitiki ezifana ne-dioctyl phthalate sekubalulekile kubakhiqizi nabalawuli ngokufanayo. Ngokuqonda lokhu, iShandong Changxing ibeka phambili ukuthuthukiswa kwemikhiqizo ye-dioctyl phthalate eqinisekile esiza ekunciphiseni umthelela wezemvelo. Ama-plasticizer abo ahambisana nezinto ezisetshenziswa kabusha eziluhlaza njenge-PET, okwenza kube lula ukukhiqizwa kwamapulasitiki asekelayo izimiso zomnotho oyindilinga. Ngokusebenzisa lezi zithako, abakhiqizi banganciphisa udoti futhi bathuthukise ukusebenziseka kabusha, okuhambisana nezinjongo zokuzinza zomhlaba wonke.

Ngaphandle komklamo womkhiqizo, iShandong Changxing yenza imikhuba eqinile yokuphatha imvelo kuyo yonke imikhiqizo yayo. Lezi zinhlelo zihlanganisa ukunciphisa ukukhishwa, ukuthuthukisa ukusetshenziswa kwamandla, nokuphatha imfucuza ngendlela efanele. Ukuzinikela kwenkampani ekusimameni kubhalwe phansi ngezitifiketi nokuthobela izindinganiso zemvelo zamazwe omhlaba. Ngokukhetha i-dioctyl phthalate eShandong Changxing, amaklayenti awatholi izinzuzo zobuchwepheshe kuphela kodwa futhi anikela ngomzamo omkhulu wokulondolozwa kwemvelo. Lezi zinhlelo zibalulekile ekubhekaneni nezinselelo zokuguquguquka kwesimo sezulu nasekukhuthazeni ukukhula kwezimboni okusimeme.

Ukwethulwa kwentela ye-carbon e-European Union kuphakamise isidingo sokuthi abakhiqizi bamukele izinto zemvelo kanye nezengezo ezinciphisa ukukhishwa kwe-carbon. Imikhiqizo ye-dioctyl phthalate kaShandong Changxing inenzuzo kakhulu ngalo mqondo. Yakhelwe ukuhlanganiswa ne-PET egaywe kabusha nezinye izinto ezisimeme, lezi plasticizers zinika amandla abakhiqizi ukuthi bafanelekele ukuncishiswa kwentela ye-carbon ngokunciphisa ukukhishwa kwegesi elibangela umphumela we-greenhouse ohlobene nokukhiqizwa kopulasitiki. Lesi sivuseleli sezimali sisekela amabhizinisi ekuthobeleni izinqubomgomo zemvelo ze-EU ngenkathi kugcinwa amanani ancintisanayo.

Ngaphezu kwalokho, iShandong Changxing ihlinzeka ngosizo lobuchwepheshe nezeluleko ukuze kusizwe amaklayenti ukuthi athuthukise izindlela zokupheka ukuze kutholwe izinzuzo ezinkulu zemvelo. Ubuchwepheshe babo buqinisekisa ukuthi imikhiqizo yepulasitiki ifinyelela amazinga okusebenza adingekayo ngaphandle kokudela izinhloso zokuzinza. Ngokuhlanganisa i-dioctyl phthalate evela eShandong Changxing, abakhiqizi bangathuthukisa isikhundla sabo semakethe e-EU nakwezinye izifunda lapho ukuhambisana nemvelo kuyimpoqo. Le nhlanganisela phakathi kokusha komkhiqizo nezinhlaka zokulawula igcizelela inani lezinhlaka zokukhetha izengezo yepulasitiki ezihambisana nemvelo.

I-Dioctyl phthalate iseyingxenye ebalulekile kwezobuchwepheshe bezengezo zamaplastiki, ihlanganisa isikhala phakathi kokusebenza kahle nokusimama. I-Shandong Changxing Plastic Additives Co., Ltd ibonisa ukuthi ubuchwepheshe obusha kanye nomthwalo wemfanelo wezemvelo kungahamba kanjani ndawonye, ​​inikeza i-dioctyl phthalate esezingeni eliphezulu esekela ukukhiqiza okuluhlaza kanye nokuthobela imithetho eqinile njengezise-EU market. Imikhiqizo yabo ayithuthukisi nje kuphela ukuguquguquka nokuqina kwamaplastiki kodwa futhi isiza ukunciphisa izintela zekhabhoni nemithelela yezemvelo ngokuvumela ukusetshenziswa kwezinto ezisetshenziswe kabusha.

Ezinkampanini ezihlose ukwamukela izindlela ezisimeme ngenkathi kuthuthukiswa ikhwalithi yomkhiqizo, ukubambisana neShandong Changxing kunikeza ithuba eliqinisekile. Ukuzibophezela kwabo ekuqiniseni, intengo yokuncintisana ye-dioctyl phthalate, kanye nokuqanjwa okusha okuqhubekayo kubenza babe ngumholi embonini yezinye izinto zamaplastiki. Ukuthola okwengeziwe ngemikhiqizo yabo kanye nezinhlelo zokusimama, vakashela i-Imikhiqizo ikhasi noma uhlole indaba yabo yenkampani ku Mayelana Nathi ikhasi. Ukwamukela i-dioctyl phthalate evela eShandong Changxing kuyisinyathelo samasu sokuya ekukhiqizeni amaplastiki aluhlaza kanye nekusasa elisimeme kakhudlwana.
