Igama lesiNgesi:N, N-diphenyl-p-phenylenediamine
Isishunqulelo sesiNgesi:DPPD
I-CAS RN:74-31-7
1. Iimpawu zomzimba kunye neekhemikhali:
1.1 Ifomula yemolekyuli: C18H16N2
1.2 Ubunzima bemolekyuli: 260.34
1.3 Ubunzima obuthile: 1.2
1.4 Ukunyibilika: Nyibilika kwi-benzene, ether kunye ne-acetone. Yinyibilikise kancinci kwi-ethanol. Ayinyibiliki emanzini.
1.5 Indawo yokubilisa: 220-225℃, 0.5mmHg
1.6 Uzinzo kunye nokusebenza kwakhona: Ukutsha. Xa ibonakaliswe emoyeni okanye elangeni, imveliso iya kuba ne-oxidized kwaye itshintshe umbala wayo. Xa udibene ne-hot dilute hydrochloric acid, iba luhlaza.
1.7 Iipropati: I-oxidation ye-latex kunye ne-rubber compounds ixhomekeke kuhlobo lwe-polymer ebandakanyekayo. Iingxaki zibandakanya utshintsho olubi lwemibala, ukulahleka kokuguquguquka, ukulahleka kwamandla okunciphisa kunye nokunciphisa ukuchasana kwempembelelo, ukuguga, ukuqhekeka kunye nokunye ukuwohloka kwendawo. I-Rubber Antioxidants ibonelela ngokusebenza okubalulekileyo kunye nokhuseleko kwizicelo ezinje ngerabha kunye neeplastiki, ukukhusela iipolymers ekuthotyweni kwe-oxidative ngenxa yobushushu, ukukhanya, ukufiphala kwegesi, iiperoxides, ukucheba, kunye nezinye izinto ezinamandla. I-DPPD i-antioxidant H inikeza ukuzinza okuphezulu kwexesha elide lobushushu kunye nokuzinza kombala; iyasebenza kwifilim, ifayibha, kunye namanqaku anqamlezayo angqindilili; kwaye isebenza kakuhle kwiinkqubo ezizaliswe ngokupheleleyo.

I-Antioxidant H / DPPD ingasetyenziselwa njenge-antioxidant kwi-propellant eqinile yokuphucula ukuzinza kokugcinwa kwemveliso. Isetyenziselwe ezo zendalo, i-styrene-butadiene, i-acrylonitrile-butadiene, i-butadiene, i-butyl, i-hydroxyl, irabha ye-polyisoprene ukuba ibe nokusebenza njengobomi obuhle obuguquguqukayo kunye nokuthanda ukunyusa imodyuli yokuqina, ukomeleza umsebenzi wokukhusela kwi-oksijeni eshushu, i-ozone. kunye nezinye iintsimbi eziyingozi ezifana nekopolo, imanganese engenafuthe ekutshatyalalisweni kwezo rabha. Iyakwazi ukusombulula ingxaki yokwaluphala ekhoyo kwiimveliso zerabha ezinombala onzulu ngelixa i-antioxidant H isetyenziswa kunye ne-antioxidant D. Ngaphezu koko, inokusetyenziswa njenge-stabilizer eshushu-oksijini kwezo plastiki zobunjineli ezifana ne-polyethylene, i-polypropylene, i-polyamide, i-polyformaldehyde ukuya. baphucule ukusebenza kwabo ukumelana nemozulu.
Sebenzisa: I-1) I-Antioxidant H / DPPD (N, N'-Diphenyl-p-phenylenediamine) isetyenziswe njenge-antioxidant kunye ne-stabilizer ye-rubber, i-petroleum oils kunye nokutya. Ikwasetyenziswa njenge-polymerization inhibitor kunye ne-retardant ngokuchasene nokuthotywa kobhedu. Yikhemikhali ephakathi ukwenza idayi, iziyobisi, iiplastiki, kunye nezongezo zokucoca.
I-2) I-Antioxidant H / DPPD iphinda isetyenziswe ekuveliseni i-polyolefins ezinzileyo engenambala kunye neefilimu ze-PVC kunye ne-PVB.
I-3) I-Antioxidant H / DPPD isetyenziswa ngokubanzi kwiindawo ezininzi zendalo kunye ne-synthetic lattices kunye neerubha.
Ukupakisha:Isingxobo esilukiweyo esifakwe ingxowa yeplastiki, ubunzima bomnatha obungama-20 kg/ibhegi.
Ugcino: Igcinwe kwindawo epholileyo, nengena umoya. Ubomi beshelufu ziinyanga ezili-12 emva komhla womvelisi. Isafumaneka ukuba iziphumo zovavanyo kwakhona zifanelekile emva komhla wokuphelelwa
Imiyalelo yokhuseleko: Inetyhefu. Iiglavu zerabha, isiphefumlo kunye nokhuseleko lwamehlo kufuneka zisetyenziswe ngexesha lomsebenzi xa udibana nolusu, ukudibana kwamehlo.
Ezothutho:Kuphephe imvula, ukuvezwa, ubushushu obuphezulu.
