I-Dioctyl Phthalate (DOP/DEHP) I-Plasticizer

Iyini i-Dioctyl Phthalate (DOP)?

I-Dioctyl Phthalate, evame ukufushaniswa njenge-DOP, igama lemakethe lendabuko le-Bis(2-ethylhexyl) Phthalate noma i-DEHP, CAS 117-81-7.

Iwuketshezi olunamafutha angenambala ukuya kokuphuzi okuphaphathekile olusetshenziswa ngokuyinhloko njengepulasitiki ekwenziweni okuvunyelwe kwePVC yezimboni. I-DOP inyusa ukuguquguquka, isekela ukucutshungulwa futhi isiza ukunciphisa ubulukhuni bezinto eziqinile ze-polymer.

Leli khasi lisebenzisa okuthi 'DOP' ukuze liqonde i-DEHP, CAS 117-81-7. Abathengi kufanele bahlale beqinisekisa inombolo ye-CAS ngoba igama elithi Dioctyl Phthalate lingadida.

Ulwazi Lomkhiqizo we-DOP

Ingabe i-DOP isho i-DEHP, i-DNOP noma i-DOTP?

I-DOP isetshenziswa ngokungaguquki ekuhwebeni kwamazwe ngamazwe. Inombolo ye-CAS kufanele ifakwe kukho konke ukucaciswa, ikhotheshini, i-SDS kanye ne-oda lokuthenga.

I-DOTP akulona elinye igama le-DOP. Inesakhiwo samangqamuzana esihlukile, iphrofayili yokulawula kanye nenombolo ye-CAS.

I-DOP iyenza kanjani ipulasitiki ye-PVC?

Ama-molecule e-DOP azibeka phakathi kwamaketanga e-polymer e-PVC futhi andise ukuhamba kwamangqamuzana. Lokhu kwehlisa ukuqina kwempahla futhi kusiza ukukhiqiza inhlanganisela ethambile, evumelana nezimo.

Ukusebenza kokugcina kuncike ekulayisheni kwe-DOP, uhlobo lwe-resin ye-PVC, izihlungi, iziqinisi, izimo zokucubungula nezinye izithasiselo.

Ngenxa yokuthi i-DOP ayiboshiwe ngamakhemikhali ku-PVC, ukufuduka, ukukhishwa kanye nokuguquguquka kufanele kuhlolwe ngezimo zesevisi ezihlosiwe.

Yiziphi Izichasiselo ze-DOP Okufanele Abathengi Baziqhathanise?

Ikhotheshini kufanele ihlonze indlela yokuhlola nemikhawulo eqinisekisiwe kunokusebenzisa kuphela amagama athi 'ukuhlanzeka okuphezulu' noma 'ibanga le-premium.'

Isetshenziswa kuphi i-DOP?

Lapho imithethonqubo kanye nokucaciswa kwekhasimende kuvuma, i-DOP ingahlolwa ku:

• Izinhlanganisela ze-PVC eziguquguqukayo

• Ikhebula lezimboni kanye nokufakwa kwezintambo

• Amashidi we-PVC namafilimu

• Isikhumba sokwenziwa

• Amapayipi wezimboni

• Izindwangu zaphansi nezimboziwe

• Ukwakhiwa kwe-Plastisol

• Ama-Adhesives, ama-sealants kanye nama-coatings akhethiwe

• I-Rubber kanye ne-polymer-processing formulations

Ukufaneleka kufanele kubuyekezwe kumakethe ngayinye yendawo kanye nomkhiqizo osuphelile. I-DOP akufanele iphromothwe ngokuzenzakalelayo kumathoyizi, imikhiqizo yokunakekela izingane, izinto zokuxhumana nokudla, imikhiqizo yezokwelapha noma okunye ukusetshenziswa okukhawulelwe.

Imaphi Amasheke Okulawula Adingekayo?

I-DEHP ingaphansi kwemikhawulo ebalulekile ezimakethe eziningi.

E-European Union, i-DEHP isohlwini Lwezinto Ezikhathazayo Kakhulu futhi imbozwe yimikhawulo ye-REACH. I-EU RoHS ikhawulela i-DEHP ku-0.1% ngesisindo ezintweni ezilinganayo ngaphakathi kwendawo yayo, kuncike ekukhululweni okusebenzayo.

E-United States, amathoyizi ezingane nama-athikili okunakekela izingane aqukethe i-DEHP engaphezu kuka-0.1% ezingxenyeni zengxenye efinyelelekayo awavunyelwe.

Ngaphambi koku-oda i-DOP, qinisekisa:

1. Izwe okuyiwa kulo

2. Isigaba somkhiqizo oqediwe

3. Izidingo ze-REACH kanye ne-SVHC

4. Izidingo ze-RoHS

5. Uhlu lwezidakamizwa ezikhawulelwe yikhasimende

6. Izimemezelo ezidingekayo nemibiko yokuhlaziya

7. Ukuthi i-plasticizer engeyona i-phthalate noma enye iyadingeka

Isimemezelo somphakeli sisodwa asinqumi ukuthi umkhiqizo osuphelile uyahambisana yini nemithetho yendawo.

I-DOP noma enye i-Plasticizer?

I-plasticizer efanelekile incike ezidingweni zokulawula kanye nezinhloso zokusebenza.

Ezinye izindlela ezingenzeka zihlanganisa i-DOTP, i-DINP, i-DPHP, i-TOTM kanye namanye amapulasitiki angewona ama-phthalate. Akukona ukushintshwa okuqondile kokukodwa kuya koyedwa kukho konke ukwakhiwa.

Ngaphambi kokushintsha ama-plasticizers, qhathanisa:

• Ukusebenza kahle kwe-Plasticizing

• Ukuguquguquka kwezinga lokushisa eliphansi

• Ukuguquguquka

• Ukufuduka nokumelana nokukhipha

• Izakhiwo zikagesi

• I-Plastisol viscosity

• Icubungula izinga lokushisa

• Ukwamukelwa ngokomthetho

• Isamba sezindleko zokwakhiwa

Ukuhlanganiswa kwelabhorethri kanye nokuhlolwa komkhiqizo oqediwe kufanele kuqedwe ngaphambi kokushintshwa kwezentengiso.

Ukupakisha, Isitoreji kanye Nokusingatha

I-DOP ingase ihlinzekwe ngezigubhu, ama-IBC, ama-flexitank noma amathangi enqwaba, kuye ngenani nendawo okuyiwa kuyo.

Gcina umkhiqizo ezitsheni ezivalwe ngci, ezihambisanayo endaweni epholile nengena umoya. Ivikele ekungcoleni, ejenti eqinisa i-oxidizing kanye nokukhishwa okungalawuleki kwemvelo.

Sebenzisa amagilavu ​​afanelekile, izingubo zokuzivikela kanye nokuvikela amehlo. Vimbela ukukhishwa emiseleni, enhlabathini nasezindleleni zamanzi. Bheka Ishidi Ledatha Yezokuphepha lamanje ngaphambi kokuphatha.

Kungani Umthombo we-DOP uvela ku-AOZUN?

I-AOZUN ingasekela abathengi bezimboni nge:

• Ukucaciswa nokumatanisa kwebanga

• I-COA, i-SDS kanye nokwesekwa kwamadokhumenti ezobuchwepheshe

• Ukuhlolwa kwesampula

• Isigubhu, i-IBC, i-flexitank noma ukuthunyelwa ngobuningi

• Ukubuyekezwa kwedokhumenti yemakethe yendawo

• Ukuqinisekiswa kwekhwalithi yangaphambi kokuthunyelwa

• Enye i-plasticizer sourcing lapho kudingeka

Ukutholakala, imibhalo yokulawula kanye nokucaciswa okuqinisekisiwe kufanele kuqinisekiswe nge-oda ngalinye.

I-Dioctyl Phthalate FAQ

Ingabe i-DOP iyafana ne-DEHP?

Ezimakethe eziningi ze-plasticizer, i-DOP ibhekisela ku-DEHP ene-CAS 117-81-7. Inombolo ye-CAS kufanele ihlale iqinisekiswa ngoba 'dioctyl phthalate' ingahunyushwa nangokuthi i-DNOP.

Ingabe i-DOP iyafana ne-DOTP?

Cha. I-DOP/DEHP iyi-ortho-phthalate, kuyilapho i-DOTP iyi-plasticizer ye-terephthalate ene-CAS 6422-86-2.

Ingabe i-DOP iyikhemikhali ephilayo noma engaphili?

I-DOP i-organic ester. Ihlukaniswa njenge-phthalate plasticizer kanye nesengezo se-polymer.

Ingabe i-DOP ingasetshenziswa kumathoyizi noma emikhiqizweni yokunakekela izingane?

I-DEHP ikhawulelwe kumathoyizi nemikhiqizo yokunakekela izingane ezimakethe ezinkulu. Imithethonqubo esebenzayo kufanele ihlolwe ngaphambi kwanoma yikuphi ukusetshenziswa noma ukuthengisa.

Ingabe i-DOTP ingakwazi esikhundleni se-DOP ngokuqondile?

Hhayi ngokuzenzakalelayo. Le mikhiqizo yomibili inezinto ezihlukene zokucubungula, ukufuduka kanye nezici zokulawula. Kudingeka isivivinyo sokwenza.

Cela ikhotheshini ye-DOP

Xhumana ne-AOZUN ngenombolo ye-CAS edingekayo, ukucaciswa, isicelo, ukupakisha, inani le-oda, indawo okuyiwa kuyo kanye nezidingo zedokhumenti yokulawula.

Singasiza ukuqinisekisa umkhiqizo olungile we-DOP/DEHP futhi silungiselele ikhotheshini yezicelo ezivunyelwe zezimboni.
