Igama lesiNgisi:I-N, i-N-diphenyl-p-phenylenediamine
Isifinyezo sesiNgisi:I-DPPD
I-CAS RN:74-31-7
1. Izakhiwo zomzimba nezamakhemikhali:
1.1 Ifomula yama-molecule: C18H16N2
1.2 Isisindo sama-molecule: 260.34
1.3 Ubukhulu obuthile: 1.2
1.4 Ukuncibilika: Ncibilika ku-benzene, i-ether kanye ne-acetone. Ncibilika kancane ku-ethanol. Ayincibiliki emanzini.
1.5 Iphuzu lokubila: 220-225℃, 0.5mmHg
1.6 Ukuqina kanye nokusabela: Kuyavutha. Uma ivezwa emoyeni noma elangeni, umkhiqizo uzoncibilikiswa bese ushintsha umbala wawo. Uma uthintana ne-hydrochloric acid eshisayo, uba luhlaza okotshani.
1.7 Izakhiwo: Ukushiswa kwe-latex kanye namakhemikhali enjoloba kuncike ohlotsheni lwe-polymer ehilelekile. Izinkinga zifaka phakathi izinguquko zombala ezimbi, ukulahlekelwa ukuguquguquka, ukulahlekelwa amandla okudonsa kanye nokunciphisa ukumelana nomthelela, ukuguga, ukuqhekeka kanye nokunye ukuwohloka kobuso. Ama-antioxidants enjoloba ahlinzeka ngokusebenza okubalulekile kanye nokuvikelwa ekusetshenzisweni okufana nenjoloba kanye nepulasitiki, evikela ama-polymer ekuwohlokeni kwe-oxidative ngenxa yokushisa, ukukhanya, ukufiphala kwegesi, ama-peroxide, ukucheba, nezinye izinto ezishintshashintshayo. I-DPPD antioxidant H inikeza ukuzinza kokushisa kwesikhathi eside kanye nokuqina kombala; isebenza kahle kumafilimu, i-fiber, kanye nezinto ezihlanganisiwe ezibanzi; futhi isebenza kahle ezinhlelweni ezigcwele.

I-Antioxidant H/DPPD ingasetshenziswa njenge-antioxidant ku-propellant eqinile ukuthuthukisa ukuzinza komkhiqizo. Isetshenziswe kulawo manzi emvelo, i-styrene-butadiene, i-acrylonitrile-butadiene, i-butadiene, i-butyl, i-hydroxyl, i-polyisoprene rubber ukuze ibe nokusebenza okuhle njengokuqina okuhle kanye nokuthanda ukuthuthukisa i-tensile modulus, ukuqinisa umsebenzi wokuvikela ku-hot-oxygen, i-ozone kanye nezinye izinsimbi eziyingozi njengethusi, i-manganese ngaphandle kwethonya ekuvuvukeni kwalawo ma-rubber. Ingaxazulula inkinga yokuguga ekhona emikhiqizweni yerabha enombala ojulile kuyilapho i-antioxidant H isetshenziswa kanye ne-antioxidant D. Ngaphezu kwalokho, ingasetshenziswa futhi njengesiqinisi se-hot-oxygen kulawo mapulasitiki obunjiniyela njenge-polyethylene, i-polypropylene, i-polyamide, i-polyformaldehyde ukuthuthukisa ukusebenza kwawo okumelana nesimo sezulu.
Ukusetshenziswa: 1) I-Antioxidant H/DPPD (N,N'-Diphenyl-p-phenylenediamine) isetshenziswa njenge-antioxidant kanye ne-stabilizer yerabha, uwoyela we-petroleum kanye nokudla. Iphinde isetshenziswe njenge-polymerization inhibitor kanye ne-retardant yokulwa nokubola kwethusi. Iyindlela yamakhemikhali yokwenza udayi, izidakamizwa, ipulasitiki, kanye nezithasiselo zokuhlanza.
2) I-Antioxidant H/DPPD isetshenziswa futhi ekukhiqizweni kwama-polyolefin azinzile angenambala kanye namafilimu e-PVC kanye ne-PVB.
3) I-Antioxidant H/DPPD isetshenziswa kabanzi kuma-lattices nama-raber amaningi emvelo nawokwenziwa.
Ukupakisha:Isikhwama esilukiwe esifakwe isikhwama sepulasitiki, isisindo esiphelele singama-20 kg/isikhwama.
Isitoreji:Igcinwa endaweni epholile, enomoya opholile. Isikhathi sokuphila seshelufu siyizinyanga eziyi-12 kusukela ngosuku lomkhiqizi. Isatholakala uma imiphumela yokuhlolwa kabusha iqinisekisiwe ngemva kosuku lokuphelelwa yisikhathi.
Imiyalelo yokuphepha:Ubuthi. Amagilavu erabha, umshini wokuphefumula kanye nokuvikela amehlo kumele kusetshenziswe ngesikhathi sokuhlinzwa uma kwenzeka ukuthintana kwesikhumba, noma ukuthintana kwamehlo.
Ezokuthutha:Gwema imvula, ukuchayeka, izinga lokushisa eliphezulu.
