I-Dioctyl phthalate (DOP) iyinto esetshenziswa kakhulu eyenza amaplastiki abe yinyama, esetshenziswa kabanzi ekwenzeni amaplastiki aguquguqukayo. Inendima ebalulekile ekuthuthukiseni ukuguquguquka, ukuqina, nokuphila isikhathi eside kwe-polyvinyl chloride (PVC) nezinye izinto eziyimpushana. Ngenxa yezici zayo ezisebenzayo zokwenza amaplastiki abe yinyama, i-DOP isetshenziswa kabanzi ezimbonini ezifana nezimoto, ezokwakha, ukupakisha, kanye nezimpahla zabathengi. Ukubaluleka kwe-dioctyl phthalate akugcini nje ekuthuthukiseni ukusebenza komkhiqizo kodwa futhi nasekubeni yonga izindleko nokuhambisana nezinhlobonhlobo zezinto eziyimpushana. Njengoba izimboni ziqhubeka nokubeka phambili izixazululo zezinto ezizinzile neziphumelelayo, ukuqonda indima ehlukahlukene ye-DOP kubaluleke kakhulu kubakhiqizi nababambiqhaza.

I-Shandong Changxing Plastic Additives Co., Ltd. ingumkhiqizi ohamba phambili ochwepheshe ekukhiqizeni i-dioctyl phthalate esezingeni eliphezulu kanye nezinye izinto ezithambisa ipulasitiki. Le nkampani izibophezele ekuthuthukiseni ubuchwepheshe obusimeme bezinto zokuthambisa ipulasitiki, inikeza imikhiqizo ehlangabezana namazinga omhlaba wekhwalithi ngenkathi isekela imizamo enobungani nemvelo. Ubuchwepheshe babo ekukhiqizeni i-DOP enokusebenza okuthuthukisiwe ububeke njengomdlali onokuncintisana emakethe yomhlaba wonke, ikakhulukazi ezinhlelweni ezibandakanya izinto ezisetshenziswe kabusha nezisimeme.

I-Dioctyl phthalate iyi-ester ye-phthalic acid ne-2-ethylhexanol, ebonakala ngefomula yayo yekhemikhali ethi C24H38O4. Isakhiwo sayo samajukujukwana siqukethe izintambo ezinde ze-alkyl ezinikeza ukuhambisana okuphezulu nezintambo zamapolymer, okuholela ekuthuthukisweni kokuguquguquka nokuthamba kwemikhiqizo yepulasitiki. Ukuqina kwamakhemikhali kwe-DOP ngaphansi kwezimo ezahlukahlukene zokushisa nezemvelo kuyenza ibe yisinqumo esihle kakhulu sama-plasticizer ezicelo eziningi zezimboni.

Njengento eyenza ipulasitiki ibe ngezansi, i-DOP isebenza ngokungena phakathi kwezintambo ze-polymer, yehlisa amandla aphakathi kwezintambo futhi yandise ukuhamba kwezintambo. Lesi senzo sehlisa izinga lokushisa lokuguquguquka kwe-polymer, sivumela ipulasitiki ukuba ibe ngezansi futhi imelane nokuqhekeka noma ukuba yize. Ngaphezu kwalokho, i-dioctyl phthalate ibonisa ukumelana okuhle nokuthuthela nokuphefumula, okubalulekile ukugcina ubuqotho bomkhiqizo isikhathi eside.

Imakethe yomhlaba wonke ye-dioctyl phthalate ibone ukukhula okuqhubekayo okuqhutshwa ukufunwa okukhulayo embonini yokwakha, ezimoto, kanye neyezinto zikagesi. Abakhiqizi abakhulu batholakala ikakhulukazi e-Asia, eYurophu, naseNyakatho Melika, lapho iChina iyisikhungo esibalulekile sokukhiqiza. Izinkampani ezifana neShandong Changxing Plastic Additives Co., Ltd zisebenzise ubuchwepheshe bokukhiqiza obuthuthukisiwe kanye nokubekwa kwamasu ukuze zandise isabelo sabo semakethe, ikakhulukazi ekuhlinzekeni i-European Union lapho ukufunwa kwezithako ezisimeme kukhula khona.

Umthamo wokukhiqiza wamanje we-DOP uthonywa yizinto ezifana nokutholakala kwezinto zokusetshenziswa, imithetho yezemvelo, kanye nentuthuko yezobuchwepheshe. Imakethe incintisana kakhulu, lapho abadlali abasemqoka begxile kukhwalithi yomkhiqizo, ukusebenza kahle kwezindleko, kanye nokuthobela imithetho eguquguqukayo. Ngaphezu kwalokho, intengo ye-dioctyl phthalate iyahlukahluka kuye ngokuguquguquka kwe-supply chain, amanani kawoyela ongahluziwe, kanye nokushintshashintsha kwesidingo esifundeni, lapho intengo ye-dioctyl phthalate ihlala iyinto ebalulekile kubakhiqizi nabasebenzisi bokugcina ngokufanayo.

Ukwesaba ngobuthi nomthelela wezinto ezithinta imvelo ezivela kuma-plasticizer e-phthalate, okubalwa i-DOP, kuholele ekubhekweni kabanzi yizinhlaka ezilawulayo emhlabeni wonke. Izifundo ziye zavusa imibuzo ngemiphumela engaba yingozi emzimbeni kanye nokuphikelela kwenhlanganisela kule ndawo. Ngenxa yalokho, imithetho eqinile, ikakhulukazi e-European Union naseNyakatho Melika, isetshenzisiwe ukukhawulela ukusetshenziswa kwama-phthalates athile noma ukuphoqelela amazinga aphephile aqinile.

Ngenxa yalokho, imboni ibone ukushintsha okukhulayo okubheke kwezinye izindlela eziphephile nezihambisana nemvelo, njenge-dioctyl terephthalate kanye nama-plasticizer asuselwa kubhayoloji. Lezi ezinye izindlela zihlose ukunciphisa ubungozi kwezempilo kanye nomthelela emvelweni ngenkathi kugcinwa izinzuzo ezisebenzayo ze-DOP yakudala. I-Shandong Changxing Plastic Additives Co., Ltd isekela lokhu kushintsha ngokunikeza izixazululo ze-plasticizer eziluhlaza ezihambisana nezinto ezisetshenziselwa ukwenziwa kabusha ze-PET. Imikhiqizo yabo iqhuba isandla kakhulu ekunciphiseni izintela zekhabhoni emakethe ye-EU ngokuhambisana nezinqubo zokukhiqiza ezisimeme kanye nezinqubomgomo zomnotho oyindilinga.

Unyaka wezi-2023 ubuchazwa yizinguquko ezishukumisayo emakethe ye-dioctyl phthalate, okugqame kuyo ukwanda kwesidingo sezithako zamapulasitiki ezisimeme nezisetshenziswe kabusha. Ukuphazamiseka kwezinto ezithunyelwayo, ukungazinzi kwamanani ezinto zokusetshenziswa, kanye nokwanda kwengcindezi yemithetho kube yizinselele kubakhiqizi emhlabeni wonke. Noma kunjalo, izinkampani ezitshala imali kwezobuchwepheshe obusha nobuhlaza ziye zakwazi ukubhekana nalezi zinselele ngempumelelo.

Enye yezinto ezivelele kakhulu ukwanda kokuqwashisa kwabathengi kanye nesidingo semikhiqizo enesibopho kwemvelo, okushukumisa abakhiqizi ukuthi bamukele ama-plasticizer asekelayo izinhloso zokusimama. Isidingo se-dioctyl terephthalate nezinye izidakamizwa ze-dop ezinganabuthi kakhulu siyanda, sibonisa lezi zinguquko ezintandweni zemakethe. Ngaphezu kwalokho, intengo ye-dioctyl phthalate ithonywe yilezi zimo zokunikezwa nokufunwa, okukhuthaza ababambiqhaza ukuthi bahlole izindlela ezisebenza kahle kwezindleko futhi ezihambisana nemithetho.

Ngokubheka phambili, imakethe ye-dioctyl phthalate kulindeleke ukuthi iguquke kakhulu ngokuthuthuka kwemikhuba ye-green chemistry nokwamukelwa okwandayo kwezithako ezizinzile. Abakhiqizi abafana neShandong Changxing Plastic Additives Co., Ltd balungele ukuhola le ngunguquko ngokwandisa uhlu lwabo lwezithako ze-plasticizers ezinganaki umonakalo emvelweni, ikakhulukazi lezo eziklanyelwe izicelo ze-recycled PET. Lokhu kubaluleke kakhulu emakethe yaseYurophu, lapho ukuncishiswa kwentela ye-carbon kukhuthaza ukusetshenziswa kwezinto ezizinzile.

Imizwa yabathengi ngokuhamba kwesikhathi iyakhetha imikhiqizo enomthelela omncane kwezemvelo, okuzokwenza ukuthi kudingeke izinto zokubopha eziphephile nezixazululo zokupakisha ezintsha. Imigomo yemithetho izoqhubeka nokuqinisa, iphoqe imboni ukuthi ibe noguquko olukhulu namazinga aphephile emakhemikhali. Ukutshalwa kwezimali ocwaningweni nasekuthuthukisweni cishe kuzokwanda, kuholele ekuphumeleleni okukhulu kumakhemikhali e-dop kanye nezinto ezizobuyisela ezilinganisela ukusebenza nokusimama.

Ezinkampanini ezifuna ukujulisa ukuqonda kwazo ngendawo ye-dioctyl phthalate, imibiko ephelele yocwaningo lwemakethe ihlinzeka ngedatha ebalulekile ngemikhuba yokukhiqiza, ukubeka amanani, izibuyekezo zemithetho, kanye nokuhlaziywa kokuncintisana. Lezi zinsiza zisiza ababambiqhaza ukuba benze izinqumo ezinolwazi mayelana nokuthenga, ukuthuthukiswa komkhiqizo, kanye namasu okungena emakethe.

I-Shandong Changxing Plastic Additives Co., Ltd inikeza ulwazi oluningiliziwe lomkhiqizo kanye nokwesekwa kwezobuchwepheshe, olutholakala ngokusebenzisa izinkundla zabo eziku-inthanethi. Abantu abanentshisekelo bangahlola uhla lwabo lomkhiqizo kanye neziyalezo zokuzinza ngokuvakashela ikhasi le-Imikhiqizo. Imininingwane eyengeziwe yenkampani, okubandakanya ukuzibophezela kwabo ekwenzeni izinto ezintsha kanye ne-green chemistry, iyatholakala ekhasini le-Mayelana Nathi.

I-Dioctyl phthalate ihlala iyisishintshi sepulasitiki esibalulekile ekwenzeni amapulasitiki aguquguqukayo, ihlinzeka ngezinzuzo ezibalulekile zokusebenza kuzo zonke izimboni eziningi. Naphezu kokusetshenziswa kwayo, izinkinga zezempilo nezokusing environment ezihlotshaniswa ne-DOP ziye zavuselela ukuguqukela kwezindlela eziluhlaza kanye nemithetho eqinile. Abakhiqizi kufanele bahlale benolwazi ngezimo zemakethe, izindawo eziguqukayo zomthetho, kanye nezintandokazi zabathengi ukuze bahlale bancintisana.

Izinkampani ezifana neShandong Changxing Plastic Additives Co., Ltd zibonisa ubuholi ekuhlinzekeni ngezixazululo ze-DOP ezisimeme ezihambisana nemizamo yomhlaba wonke yokunciphisa ukukhishwa kwekhabhoni nokuthuthukisa ukugaywa kabusha, ikakhulukazi emakethe ye-EU. Ngokuhlanganisa ubuchwepheshe obuthuthukisiwe be-plasticizer nokugxila kuma-additives anobungani nemvelo, imboni ingafinyelela ibhalansi phakathi kokusebenza, ukuphepha, nokusimama, ivule indlela yokukhiqiza ipulasitiki entsha futhi enesibopho.

Ukuze uthole imibuzo enemininingwane eyengeziwe noma amathuba okubambisana, amabhizinisi ayakhuthazwa ukuthi avakashele i-Xhumana Nathi ikhasi ukuze uxhumane ngqo nethimba lochwepheshe beShandong Changxing Plastic Additives Co., Ltd.
