I-Dioctyl Phthalate (DOP) iyinto esetshenziswa kabanzi eyenza amaplastiki abe yinyama, edlala indima ebalulekile ekuthuthukiseni ukuvumelana nokuhlala isikhathi eside kwamaplastiki. Kubaluleke kakhulu ekwenzeni imikhiqizo ye-polyvinyl chloride (PVC), esetshenziswa ezimbonini eziningi emhlabeni jikelele. Njengento eyenza amaplastiki abe yinyama, i-dioctyl phthalate yenza izinto eziqinile zibe nethambile, zibe namandla okwelula, futhi zihlale isikhathi eside, okwenza zibe lula ukuzisebenzisa ezindaweni ezahlukene. Isidingo se-DOP esezingeni eliphezulu siqhubeka nokukhula, siqhutshwa ukusetshenziswa kwayo okuhlukahlukene ezimbonini kanye nokugcizelelwa okukhulayo kwezinto zamakhemikhali ezisimeme nezingalimazi imvelo.

Shandong Changxing Plastic Additives Co., Ltd, umkhiqizi ohamba phambili wamakhemikhali osendlini eJining, eShandong, uzibeke njengomphakeli othembekile we-dioctyl phthalate esezingeni eliphezulu. Ngokuzibophezela okuqinile ekwenzeni izinto ezintsha nasekuqhubekeni, inkampani inikeza i-DOP ehlanzekile ehlangabezana nezindinganiso eziqinile zemvelo. Lesi sihloko sihluza izici, izicelo, nezinzuzo ze-DOP, sigqamisa ukuthi kungani iShandong Changxing iyisihambeli esikhethwayo samabhizinisi adinga ama-plasticizer athembekile.

I-Dioctyl phthalate, eyaziwa ngokuthi i-bis(2-ethylhexyl) phthalate, iyisidakamizwa se-phthalic acid esivame ukusetshenziswa njenge-plasticizer. Kuyinto ewuketshezi ecacile, engenambala, nenamafutha enokuhambisana kahle ne-PVC resins. Umsebenzi oyinhloko we-DOP ukuthambisa i-PVC ngokuzifaka phakathi kwezintambo ze-polymer, kunciphisa amandla phakathi kwezinto futhi kwandise ukuguquguquka komkhiqizo wokugcina. Lokhu kusebenzisana kwamamolekyuli kubangela izinto zepulasitiki ezibuthakathaka, ezithambile, futhi ezimelana nokuqhekeka ngaphansi kwengcindezi.

Ngokungafani nabanye abakhiqizi bepulasitiki, i-dioctyl phthalate ibonisa ukuzinza okungcono kwe-thermal nokumelana okuhle nokuthuthela nokukhipha, okwenza kube kuhle kwimikhiqizo yepulasitiki ehlala njalo. Ngaphezu kwalokho, i-DOP igqama ngokuba nenzuzo, ukutholakala kabanzi, kanye nokucubungula okulula, okufaka isandla ekuthandweni kwayo emkhakheni wokukhiqiza upulasitiki. Kubalulekile ukuhlukanisa i-DOP ku-dioctyl terephthalate, omunye umkhiqizi wepulasitiki onezici zamakhemikhali ezihlukile nezinye izicelo.

Amakhemikhali e-DOP anomlando obhalwe kahle wokuphepha uma esetshenziswa ngokwemigomo yemithetho, futhi intuthuko ekukhiqizeni iholele ezindleleni zokukhiqiza ezinganaki umthelela emvelweni, kunciphisa umthelela emvelweni. Lokhu kuhambisana nezinjongo zokugaywa kabusha okuluhlaza nezinto ezisimeme, ikakhulukazi ekukhiqizeni i-PET nasekufezeni izidingo zezintela zekhabhoni ze-EU, indawo lapho iShandong Changxing ihamba phambili.

Ukuvama kuka-Dioctyl phthalate kubonakala ezinhlotsheni eziningi zezicelo zezimboni. Kusetshenziswa kakhulu ekwenzeni i-PVC namaplastiki ukukhiqiza ama-film, ama-sheet, kanye nezinto ezibunjiwe. I-plasticizer ithuthukisa ubunewele nokuqina kwezinto ezisetshenziswa ekuphileni kwansuku zonke, kusuka ezintweni zokupakisha kuya kumadivayisi ezokwelapha.

Ekukhiqizeni isikhumba esenziwe ngesandla, i-DOP ithuthukisa ubunewele nokumelana nokuguga, okwenza kube yinto ebalulekile ezintweni ezisetshenziswa ezimotweni, ezicathulweni, kanye nefenisha. Izakhiwo zayo ezinhle kakhulu zokuvikela ugesi nazo ziyenza ibe yingxenye ebalulekile ekugcineni ucingo namakhebula, iqinisekisa ukuphepha kukagesi nokuqina. Ngaphezu kwalokho, i-DOP isetshenziswa kabanzi ezindaweni zokugqoka phansi kanye nezindonga, lapho ubunewele nokuqina kubalulekile ekusebenzeni nasekuphumuleni.

Ama-adhesives nezihlanganisi azuzwa umphumela wokwenza uplastic we-dioctyl phthalate, okuthuthukisa ukunwebeka namandla okubopha. Lesi sigaba esibanzi sezicelo sibonisa ukuthi kungani i-DOP ihlala iyikhemikhali eyisisekelo embonini yamaplastiki.

I-Shandong Changxing Plastic Additives Co., Ltd igqama emakethe ye-DOP ngenxa yokuzibophezela kwayo kwekhwalithi, ukusimama, kanye nenkonzo yamakhasimende. Le nkampani ikhiqiza i-dioctyl phthalate ehlanzekile kakhulu ngezindlela ezingalimazi imvelo ezihambisana namazinga omhlaba wezemvelo. Le ndlela ayigcini nje ngokunciphisa umthelela emvelweni kodwa futhi isiza amaklayenti ukuthi ahambisane nezimiso eziqine kakhulu, okuhlanganisa nezinzuzo ezihlobene nezinqubomgomo zentela ye-carbon ye-European Union.

Inethiwekhi ephumelelayo yezokuthutha yeShandong Changxing iqinisekisa ukulethwa ngesikhathi kwamachibi e-DOP, okusekela imijikelezo yokukhiqiza engaphazamiseki kumakhasimende emhlabeni wonke. Ukuzinikela kwabo ocwaningweni nasekuthuthukisweni kuthuthukisa njalo ukusebenza komkhiqizo nokusimama, okubenza babe ngabashintshi emkhakheni wezinto ezithambisa ipulasitiki. Ngokugxila ekugayeni kabusha okuluhlaza kanye nezithako ezisimeme, inkampani isekela umnotho oyindilinga futhi yehlisa ukuncika ezintweni ezingavuseleleki ezivela emafutheni ezilwane.

Amabhizinisi afuna abahlinzeki be-dioctyl phthalate abathembekile futhi abanomthwalo wemfanelo kwezemvelo azothola okunikezwa yiShandong Changxing kunomncintiswano kakhulu futhi kwenzelwe ukuhlangabezana nezidingo zezimboni zesimanje.

Ukubambisana neShandong Changxing ngezidingo zakho ze-dioctyl phthalate kulula futhi kugxile kumakhasimende. Amaklayenti angase acela ukuxhumana ngeziteshi zenkampani ezisezingeni eliphezulu ukuze axoxe ngezici zomkhiqizo, amanani, kanye nezimiso zokulethwa. Le nkampani ihlinzeka ngezixazululo ezenziwe ngendlela efanele ukuze kuhlanganiswe izidingo ezahlukahlukene zokukhiqiza kanye nezinketho zoku-oda eziningi ukuze kuncishiswe izindleko.

I-Shandong Changxing ihlinzeka ngosekelo olunzulu kuyo yonke inqubo yokuthenga, kusukela ekuceleni kokuqala kuya kusevisi yangemva kokuthengisa. Ithimba layo elinolwazi lisiza ngesiqondiso sobuchwepheshe, ukuhambisana nemithetho, kanye nokuhlelwa kwezinto zokuhambisa, liqinisekisa umuzwa wokuhlinzekwa okungenamaphutha. Ezinkampanini ezihlola izinketho ze-plasticizer, iShandong Changxing ihlinzeka hhayi kuphela nge-DOP esezingeni eliphezulu kodwa futhi nobudlelwano obuthembekile bokukhula okuzinzile.

Ukuthola okwengeziwe ngohlu lwabo oluphelele lwemikhiqizo namakhono enkampani, vakashela i-Imikhiqizo ikhasi. Ukuze uthole imibuzo eqondile nokwesekwa, thintana ne-Xhumana Nathi ikhasi.

I-Dioctyl phthalate iseyinto ebalulekile yokuhlanganisa ipulasitiki embonini yamapulasitiki ngenxa yekhono layo elihle kakhulu lokuthuthukisa ukuguquguquka, ukuqina, nokusebenza kwezinto. Izicelo zayo zihlanganisa imikhakha eminingi, kusukela ekwenzeni i-PVC kuya kuma-adhesives, isikhumba esenziwe ngesandla, nokuvikela ugesi. Ukukhetha umphakeli we-eco-conscious ocebile njenge-Shandong Changxing Plastic Additives Co., Ltd kuqinisekisa ukuthi amabhizinisi azuzwa hhayi kuphela ngekhwalithi yomkhiqizo ephakeme kodwa futhi nemikhuba yokukhiqiza eqhubekayo, ehambisana nezimfuno zemakethe yomhlaba wonke.

Ukugxila kweShandong Changxing ekugayeni kabusha okuluhlaza kanye nama-plasticizer e-PET ahlala njalo kubeka kahle ukusekela amaklayenti abhekana nemithetho yezemvelo njenge-EU carbon tariff. Ubuholi babo kwezobuchwepheshe, ukunakekelwa kwemvelo, kanye nenkonzo yamakhasimende kubenza bakhethe kakhulu i-dioctyl phthalate namakhemikhali ahlobene.

Thola okwengeziwe ngomsebenzi ophayona weShandong Changxing kanye nemikhiqizo yabo ngokuvakashela i-Ikhaya kanyeMayelana Nathi amakhasi ukuze uhlole umgomo wenkampani kanye nobuchwepheshe bezimboni ngokuningiliziwe.
