I-Antioxidant H CAS 74-31-7 I-Antioxidant DPPD
Igama lesiNgesi:I-N, i-N-diphenyl-p-phenylenediamine
Isifinyezo sesiNgesi:I-DPPD
I-CAS RN:74-31-7
1. Iimpawu zomzimba nezekhemikhali:
1.1 Ifomula yemolekyuli: C18H16N2
1.2 Ubunzima beemolekyuli: 260.34
1.3 Ubunzima obuthile: 1.2
1.4 Ukunyibilika: Nyibilikisa kwi-benzene, i-ether kunye ne-acetone. Nyibilikisa kancinci kwi-ethanol. Ayinyibiliki emanzini.
1.5 Iqondo lokubila: 220-225℃, 0.5mmHg
1.6 Uzinzo kunye nokusabela: Iyatsha. Xa ivezwa emoyeni okanye elangeni, imveliso iya kunyibilikiswa kwaye itshintshe umbala wayo. Xa idibene ne-hydrochloric acid eshushu, iba luhlaza.
1.7 Iipropati: Ukuxinana kweekhompawundi zelatex nezerabha kuxhomekeke kuhlobo lwepolymer ebandakanyekayo. Iingxaki ziquka utshintsho olubi lombala, ukulahleka kokuguquguquka, ukulahleka kwamandla okutsalwa kunye nokunciphisa ukumelana nempembelelo, ukuguga, ukuqhekeka kunye nokunye ukuwohloka komphezulu. Ii-antioxidants zerabha zibonelela ngokusebenza okubalulekileyo kunye nokhuseleko kwizicelo ezifana nerabha kunye neeplastiki, zikhusela iipolymers ekuwohlokeni kwe-oxidative ngenxa yobushushu, ukukhanya, ukufiphala kwegesi, iiperoxides, ukucheba, kunye nezinye izinto eziguqukayo. I-DPPD antioxidant H ibonelela ngokuzinza okuphezulu kobushushu bexesha elide kunye nokuzinza kombala; isebenza kakuhle kwifilimu, kwifayibha, nakwizinto ezinqamlezileyo; kwaye isebenza kakuhle kwiinkqubo ezizaliswe ngokupheleleyo.

I-Antioxidant H/DPPD ingasetyenziswa njenge-antioxidant kwi-solid propellant ukuphucula uzinzo lokugcina imveliso. Isetyenziselwe ezo ngerabha zendalo, i-styrene-butadiene, i-acrylonitrile-butadiene, i-butadiene, i-butyl, i-hydroxyl, i-polyisoprene ukuze zisebenze kakuhle njengobomi obuhle bokuguquguquka kunye nomdla wokuphucula i-tensile modulus, ukuqinisa umsebenzi wokukhusela kwi-hot-oxygen, i-ozone kunye nezinye izinyithi eziyingozi ezifana ne-copper, i-manganese ngaphandle kwempembelelo kwi-vulcanization yezo ngerabha. Ingasombulula ingxaki yokwaluphala ekhoyo kwiimveliso zerabha ezinombala onzulu ngelixa i-antioxidant H isetyenziswa kunye ne-antioxidant D. Ngaphezu koko, ingasetyenziswa njenge-hot-oxygen stabilizer kwezo plastiki zobunjineli ezifana ne-polyethylene, i-polypropylene, i-polyamide, i-polyformaldehyde ukuphucula ukusebenza kwazo okumelana nemozulu.
Ukusetyenziswa: 1) I-Antioxidant H/DPPD (N,N'-Diphenyl-p-phenylenediamine) isetyenziswa njenge-antioxidant kunye ne-stabilizer kwirabha, ii-oyile zepetroleum kunye nokutya. Ikwasetyenziswa njenge-polymerization inhibitor kunye ne-retardant ngokuchasene nokubola kobhedu. Yinto ephakathi kweekhemikhali yokwenza iidayi, amayeza, iiplastiki kunye nezongezo zesepha.
2) I-Antioxidant H/DPPD ikwasetyenziswa ekuveliseni ii-polyolefins ezingenambala ezizinzileyo kunye neefilimu ze-PVC kunye ne-PVB.
3) I-Antioxidant H/DPPD isetyenziswa kakhulu kwiilattices nakwiirabha zendalo nezenziweyo.
Ukupakisha:Ingxowa elukiweyo egqunywe ngeplastiki, ubunzima bayo buyi-20 kg/ingxowa.
Indawo yokugcina:Igcinwa kwindawo epholileyo, enomoya opholileyo. Ixesha lokugcinwa kwayo ziinyanga ezili-12 emva komhla womenzi. Isekhona ukuba iziphumo zovavanyo kwakhona ziyaqinisekiswa emva komhla wokuphelelwa.
Imiyalelo yokhuseleko:Iiglavu zerabha, isixhobo sokuphefumla kunye nesikhuselo samehlo kufuneka zisetyenziswe ngexesha lotyando xa kuthe kwadibana ulusu, okanye emehlweni.
Uthutho:Kuphephe imvula, ukuvezwa, ubushushu obuphezulu.
