Ama-antioxidant a-Antioxidants, antine antioxidants asetshenziselwa kakhulu ukuvimbela ukuguga kwe-anrmal axygen, ukuguga kwe-ozone, ukuguga okuqinile kanye ne-siteral metal catalytic oxidation, umphumela wokuvikela uhlukile. Okubi kwayo ukungcoliswa kwayo ukungcoliswa, ngokwesakhiwo kungaphinde kwehlukaniswe ku:

Isigaba se-Phenyl Naphyyyalamine: njenge-anti-a noma anti-a, i-antioxidant J noma d, i-PBNA yi-antioxidant yakudala, esetshenziselwa ubuthi, ngenxa yezizathu zobuthi, lolu hlobo lwe-antioxidant aluvaliwe ngaphakathi amazwe aphesheya.

I-Ketamine antioxidant: inganikeza i-diene rubrur ukushisa kakhulu ukushisa nokuguga kokuguga, kwezinye izikhathi ukumelana nokumelana okuhle ekusebenzeni kokuqhekeka okuguqukayo, kepha akuvami ukuthi uvimbele i-catalytic oxidation yama-ion wensimbi kanye nomsebenzi wokuguga kwe-ozone. I-agent-agent rd ye-anti yokuguga. Umenzeli wokulwa nokuguga awunawo kuphela umsebenzi we-antioxidant, futhi uvame ukusetshenziswa njenge-anti-odor oxygen ejenti.

I-Diphenyyamine Derivatives: Lawa ma-antioxidani avimbela ukusebenza kokuguga kokuguga kwe-thermal oxygen elilingana noma ngaphansi kwe-dihydroquinoline polymer, lapho isetshenziswa njenge-antioxidant, alingana ne-antioxidant d. Kepha ukuvikelwa kokuguga ukukhathala kuphansi kunalekugcina.

Ukutholwa kwe-P-Phenyleriamine: Lawa ma-antioxidants ayisigaba sama-antioxidants asetshenziswa kabanzi embonini yerabha njengamanje. Bangavimbela ukuguga kwe-ozone, ukuguga okukhathazayo, ukuguga okushisayo kwe-oxygen kanye nensimbi ion-catalyzed oxidation yemikhiqizo yenjoloba. I-Dialkyl P-phenylediamine (efana ne-UOP788). Lezi zinto zinokuguga okukhethekile kwe-ozone ozone, ikakhulukazi ukusebenza okudala okuyisisekelo ngaphandle kwepharafini, nokuvinjwa okuhle komphumela wokuguga we-thermal. Kodwa-ke, banokuthambekela kokukhuthaza ukubheja.

Ukusetshenziswa kwalezi zinto nge-Alkyl Aryl P-Phenylediamine kunganikeza ukuvikela okuhle ekugugeni kwe-ozone enamandla ashukumisayo. Eqinisweni, i-Dialkyl-P-PhenyLenimine ihlala isetshenziswa ngokuhlanganiswa ne-Alkyl-aryl-p-phenylenimine. I-Alkyl Arl P-Phenyleriane efana ne-UOP588, 6ppd. Izinto ezinjalo zivikelekile ekuvikelweni okunamandla okuqina kwe-ozone. Lapho isetshenziswa nge-paraffin wax, futhi ibonisa isivikelo esivelele ekugugeni kwe-ozone ye-static futhi imvamisa ayinayo inkinga yokufafaza isithwathwa. Izinhlobo zokuqala, ezingama-4010na, zisasetshenziswa kabanzi.

I-6DDP nayo i-antioxidant esetshenziswa kakhulu kulesi sigaba. Izizathu zalokhu ukuthi akubangeli i-dermatitis, inomthelela omncane ekuphepheni kwenqubo ngokuqhathaniswa ne-alkyl ph-phenylediamine ne-dileckyl p-phenylediamine futhi inokuthambekela okuncane kokukhuthaza, i-arkyl aryl Futhi i-dialkyl p-phenylediamine, iyi-stabilizer enhle kakhulu ye-SBR, futhi ibonisa izakhiwo ze-antioxidant. Lapho okufakiwe konke kungu-ARRY, ibizwa nge-P-Phenyleniane. Uma kuqhathaniswa ne-Alkyl AryLylediamine, kepha umsebenzi wokulwa ne-ozonation naye uphansi, futhi ngenxa yezinga lawo lokufuduka elihamba kancane, lezi zinto zinokuqina okuhle futhi zine-antioxidants ephumelelayo. Okubi kwabo ukuthi kulula ukufafaza ukhilimu enjoloba nge-solubity ephansi, kepha kuyasiza kakhulu ku-CR kungakhiqiza ukuvikelwa okuhle kakhulu. Futhi akukhiqizi inkinga yokuqhakambisa ukubheja.

Phenolic antioxidants

Lolu hlobo lwe-antioxidant lusetshenziswa ikakhulukazi njenge-antioxidant, izinhlobonhlobo ngazinye futhi zinendima yokuphumelela kwe-ion yensimbi. Kepha umphumela wokuvikela awumuhle njenge-antioxidant ye-amine, inzuzo eyinhloko yalolu hlobo lwe-antioxidant ayingcolisi, efanelekile imikhiqizo enjoloba ekhanyayo ekhanyayo.

Ukuvinjezelwa i-Phenol: Lolu hlobo lwe-antioxidant lusetshenziswa kabanzi i-antioxidant 264, i-SP kanye namanye ama-antioxidants aphezulu kakhulu, uma kuqhathaniswa nokuqina kwezinto ezinjalo ngakho-ke, kepha lezi zinto zinomphumela ophuthumayo ophansi. Umenzeli wokulwa nokuguga 264 angasetshenziswa emikhiqizweni yebanga lokudla.

Ukuvinjezelwa amaBisphenols: Izinhlobo ezisetshenziswayo ezisetshenziswayo ezingama-2246 no-2246s, umsebenzi wokuvikela nokungcoliswa kwalezi zinto ungcono kunama-venols avinjelwe, kepha lezi zinto zinganikeza ukuvikela okusebenzayo kwemikhiqizo ye-pubr yesiponji, kepha futhi kusetshenziswe imikhiqizo ye-latex .

Ama-Phenols ama-Multi-Phenols, ikakhulukazi abhekisela kokutholwa kwe-P-Phenylediamine, okufana ne-2,5-amylhydroquinone kungenye yazo, lezi zinto zisetshenziselwa ikakhulukazi ukulondolozwa kwamafilimu okuvunguvu kanye nama-adhesives, kodwa futhi ne-NBR BRIMS Stabilizer.

Uhlobo lwe-organic sulfide hlobo antioxidant

Lolu hlobo lwe-antioxidant lusetshenziswa kabanzi njenge-Stabilizer Plastikhi yePololefide njenge-hydropoxide ebhubhisa i-antioxidant. Izicelo eziningi enjoloba zingama-dithiocarbamates kanye ne-thool-based benzimidazoles. Ukusetshenziswa kwamanje kwe-dibutyl dithiocarbamate zinc. Le nto isetshenziswa kakhulu ekukhiqizweni kwe-butyl rubber stabilizer. Okunye yi-dibutyllithithithorarbaric acickel (antioxidant NBC), kungathuthukisa ukuvikelwa kwe-NBR, CR, SBRI static ozone ukuguga. Kepha ku-NR kusiza umphumela we-kang oxidation umphumela.

I-thiol-based benzimidazole

Njenge-antioxidants MB, i-MBZ, futhi ingenye yama-antioxidants ajwayelekile enjoloba, banomphumela wokuvikela olinganiselwe ku-NR, SBR, BR, NBR. Futhi avimbele i-catalytic oxidation yama-ions wethusi, izinto ezinjalo kanye namanye ama-antioxidants asetshenziswa kakhulu futhi avame ukukhiqiza imiphumela yokuvumelanisa. Lolu hlobo lokungcoliswa kwe-antioxidant luvame ukusetshenziswa emikhiqizweni enemibala ekhanyayo.

I-antioxidant engafuduki

Lapho irabha emphumeleni olungapheli lokuvikela ama-antioxidants, ebizwa ngokuthi ama-antioxidants angeleli afudukayo, amanye abizwa nangokuthi ama-antioxidants angenzi lutho noma aphikelelayo ama-antioxidants. Uma kuqhathaniswa ne-antioxidant ejwayelekile ikakhulukazi kunzima ukuyikhipha, kunzima ukuyidlala futhi kunzima ukuyidlala, ukuze i-antioxidant enjoloba ukuze idlale irabha elihlala njalo lezindlela ezine ezilandelayo:

1, Khulisa isisindo samangqamuzana e-antioxidant.
2, ukucutshungulwa kwama-antioxidants kanye nokuhlanganiswa kwamakhemikhali enjoloba.
3, i-antioxidant ixhunyelelwa kwirabha ngaphambi kokucubungula.
4, enqubweni yokukhiqiza, ukuze i-monomer enomsebenzi wokuvikela kanye ne-rubber monomer copolymerization.
I-antioxidant ezindleleni ezintathu zokugcina, kwesinye isikhathi eyaziwa nangokuthi i-antioxidant esebenzayo ye-antioxidant noma i-polymer bonding antioxidant.
