I-Dioctyl Terephthalate (DOTP/DEHT) CAS 6422-86-2

Iyini i-Dioctyl Terephthalate?

I-Dioctyl terephthalate, evame ukufushaniswa njenge-DOTP, iyi-plasticizer yenhloso evamile esetshenziswa ngokuyinhloko ku-PVC eguquguqukayo kanye nezinhlelo zokusebenza ze-polymer ezihlobene.

Igama lekhemikhali elinembe kakhulu yi-bis(2-ethylhexyl) terephthalate. Yaziwa nangokuthi yi-di(2-ethylhexyl) terephthalate noma i-DEHT.

I-DOTP ngokuvamile ivela njengoketshezi olucacile, olungenambala, olunamafutha. Inikeza ukuguquguquka kwe-polymer, ukusebenza kokucubungula, izakhiwo zezinga lokushisa eliphansi kanye nokuguquguquka okuphansi.

Ukuhlonza kwe-DOTP kanye Nezakhiwo Ezijwayelekile

Lawa manani awulwazi olujwayelekile lwereferensi. Izimfuneko zokugcina kufanele ziqinisekiswe ngokuqhathaniswa nencazelo yomkhiqizo okuvunyelwene ngayo kanye neqoqo Lesitifiketi Sokuhlaziya.

Ingabe i-DOTP i-Organic noma i-Inorganic?

I-DOTP iyinhlanganisela yezinto eziphilayo. I-ester ekhiqizwa kusuka ku-terephthalic acid ne-2-ethylhexanol.

Ngokwezentengiselwano, i-DOTP ihlukaniswa njengekhemikhali enhle, isithasiselo se-polymer noma ipulasitiki. Imvamisa isetshenziswa njengesengezo esisebenzayo esiqediwe esikhundleni sokuba ikhemikhali eliphakathi nendawo.

Uma kungakhethwa isigaba sewebhusayithi esisodwa kuphela, 'Ama-Plasticizers' noma 'Amakhemikhali Amahle' afaneleka kakhulu kunokuthi 'Ama-Intermediates.'

Ingabe i-DOTP ne-DEHT zingumkhiqizo ofanayo?

Yebo. I-DOTP ne-DEHT yizifinyezo ezivame ukusetshenziswa ze-CAS No. 6422-86-2.

I-DOTP isho i-dioctyl terephthalate, kuyilapho i-DEHT isho di(2-ethylhexyl) terephthalate. I-DEHT ichaza amaketango aseceleni atholakala ngotshwala ngokunembe kakhudlwana.

Abathengi kufanele baqinisekise inombolo ye-CAS ngoba isifinyezo 'DOP' singase sibhekisele kukhemikhali ehlukile.

I-DOTP iqhudelana ne-DOP, i-DEHP ne-DINP

I-DOTP akumele ididaniswe ne-DEHP ngoba yomibili imikhiqizo ingase ichazwe ngokungakahleleki njengokuthi 'dioctyl' amapulasitiki.

Ingabe i-DOTP Phthalate-Free?

I-DOTP i-terephthalate ester, hhayi i-ortho-phthalate ester efana ne-DEHP, DBP noma i-DINP. Ngakho-ke kuvame ukudayiswa njenge-plasticizer engeyona i-ortho-phthalate noma enye indlela ye-phthalate.

Nokho, igama elithi 'phthalate-free' lingaba nezincazelo ezihlukene zomthetho noma eziqondene nekhasimende. Abahlinzeki-mpahla akufanele benze isimangalo sokuthobela ngokuphelele ngaphandle kokuqinisekisa:

• Izwe noma isifunda esisebenzayo

• Uhlu lwezidakamizwa ezikhawulelwe

• Ukucaciswa kwekhasimende

• Indlela yokuhlola

• Uhlelo lokusebenza lomkhiqizo oqediwe okuhlosiwe

• Isimemezelo esidingekayo noma umbiko wenkampani yangaphandle

'Non-ortho-phthalate plasticizer' ngokuvamile iyincazelo enembe kakhulu ngokwekhemikhali.

I-DOTP Iyenza Kanjani Ipulasitiki Ye-PVC?

Ama-molecule e-DOTP azibeka phakathi kwamaketanga e-polymer e-PVC futhi anciphise ukukhanga kwama-intermolecular. Lokhu kwandisa ukuhamba kweketango futhi kusiza ukukhiqiza into ethambile, evumelana nezimo.

I-DOTP ingaba nomthelela:

• Ukuqina

• Izakhiwo ze-Tensile ne-elongation

• Ukuguquguquka kwezinga lokushisa eliphansi

• I-Plastisol viscosity

• Icubungula izinga lokushisa

• Ukuguquguquka

• Ukufuduka nokumelana nokukhipha

• Ukusebenza kokufakwa kukagesi

Ukusebenza kuncike kumthamo, uhlobo lwe-PVC resin, izigcwalisi, iziqinisi nezinye izinto zokwakha. Ukuhlolwa kokwakhiwa kwelabhorethri kufanele kuqedwe ngaphambi kokusetshenziswa kwezentengiso.

Isetshenziselwani i-DOTP?

Amamaki aqondene nohlelo lokusebenza angahlolwa kuma-adhesive, ama-sealant, ama-coatings, irabha kanye nezinhlanganisela ze-elastomeric.

Izicelo zezokwelapha, zokuthintwa ukudla, ithoyizi noma zokunakekela izingane zidinga ibanga elifanele kanye nemibhalo yokuthobela eqondene nesicelo. I-DOTP yezinga lezimboni akufanele yethulwe ngokuzenzakalelayo njengefanele ukusetshenziswa okulawulwayo.

Yiliphi Ibanga Le-DOTP Okufanele Abathengi Balikhethe?

Isilingo sokwakheka siyanconywa ngaphambi kokushintsha kusuka ku-DOP, DINP noma enye i-plasticizer kuya ku-DOTP.

Yiziphi Izicaciso Zekhwalithi ye-DOTP okufanele Abathengi Baziqhathanise?

Abathengi be-DOTP kufanele baqhathanise ngaphezu kokuqukethwe kwe-ester. Umbala, i-acidity, amanzi, utshwala bamahhala, ukuguquguquka nokusebenza kukagesi kungathinta ukucubungula kanye nekhwalithi yomkhiqizo ophelile.

Amabanga e-DOTP ahlanzekile ngokwezentengiselwano ngokuvamile acacisa okungenani okuqukethwe kwe-ester okungu-99.5–99.6%, umbala ophansi we-APHA, inani le-asidi ephansi namanzi alawulwayo. Lezi izinkomba zemakethe, aziqinisekisiwe izicaciso ze-AOZUN ngaphandle kokuthi ziqinisekiswe kukhotheshini nenkontileka.

Yiziphi Izivivinyo Zokusebenza Okufanele Ziqedwe ku-PVC?

Ukuhlanzeka kwamakhemikhali akubikezeli ngokuzenzakalelayo ukusebenza kukho konke ukwakhiwa. Abathengi kufanele bahlole i-DOTP kunhlanganisela ehlosiwe ye-PVC.

Ukuqhathanisa okunconyiwe kungafaka:

• Ukuqina kogu

• Amandla aqinile kanye nobude

• Ukugoba okunezinga lokushisa eliphansi noma ukonakala

• Ukuguga kwehhavini

• Ukukhipha amafutha, amanzi kanye nezihlanzi

• Ukuthuthela ezintweni eziseduze

• I-Plastisol viscosity

• I-Gelation nokuziphatha kwe-fusion

• Ukumelana nevolumu

• Ukuzinza kombala

Lapho ushintsha enye i-plasticizer, qhathanisa ukwakheka ngobulukhuni obulinganayo noma ukusebenza okulinganayo kunokuba ucabangele ukufaka esikhundleni esisodwa kuya kwesinye.

Ukupakisha, Isitoreji kanye Nokusingatha

I-DOTP kufanele ihlinzekwe ngamaphakheji ahlanzekile, avalwe ngokuqinile futhi ahambisana namakhemikhali. Izinketho zokunikezwa kwesigubhu, i-IBC noma inqwaba kufanele ziqinisekiswe ngesikhathi sekhotheshini.

Gcina endaweni epholile, eyomile futhi enomoya omuhle. Gcina iziqukathi zivaliwe futhi uvikele umkhiqizo kumswakama, ukungcola, ukushisa okudlulele kanye nezinto ezingahambelani.

Sebenzisa amagilavu ​​afanele, ukuvikela amehlo kanye nezinqubo zokulawula ukuchitheka. Ukuphatha nokugcina kufanele kulandele Ishidi Ledatha Lokuphepha lamanje kanye nemithetho yendawo.

Yimaphi Amadokhumenti Okufanele Umhlinzeki We-DOTP Ahlinzeke?

Ngokuya ngesicelo kanye nemakethe yendawo, abathengi bangacela:

• Isitifiketi Sokuhlaziya

Amadokhumenti kufanele amataniswe nebanga eliqondile, umthombo wokukhiqiza kanye nenqwaba lapho kudingeka khona.

Kungani Umthombo DOTP kusukela AOZUN?

I-AOZUN ingasiza amakhasimende ngokumadanisa ukucaciswa kwe-DOTP, ukuhlolwa kwesampula, ukukhethwa kwamaphakheji kanye nokuxhumana kwe-oda lokuhweba.

Ukuze uthole ikhotheshini enembile, sicela unikeze:

• I-polymer ehlosiwe kanye nesicelo

• Okuqukethwe kwe-ester okudingekayo

• Umbala ophezulu, i-acidity namanzi

• Izidingo zikagesi noma zokuguquguquka

• Izidingo zokulawula nokuhlola

• Inani elidingekayo

• Okuncanyelwayo kokupakisha

• Izwe okuyiwa kulo

Ukucaciswa kokugcina, ukupakishwa, ukutholakala kanye nemibhalo kuqinisekiswa ngokomkhiqizo okhethiwe kanye nokuhleleka kohwebo.
