Antioxidant H CAS 74-31-7 Antioxidant DPPD
Izina ry'Icyongereza:N, N-diphenyl-p-phenylenediamine
Incamake y'Icyongereza:DPPD
CAS RN:74-31-7
1. Imiterere y'umubiri n'imiti:
1.1 Formule ya molekile: C18H16N2
1.2 Uburemere bwa molekile: 260.34
1.3 Uburemere bwihariye: 1.2
1.4 Gushonga: Bishongesha muri benzene, eteri na asetone. Bishongesha gato muri etanoli. Ntibishongesha mu mazi.
1.5 Aho kubira: 220-225℃, 0.5mmHg
1.6 Gukomera no gukora neza: Bishobora gushya. Iyo bihuye n'umwuka cyangwa izuba, icyo gicuruzwa kizahinduka ogisijeni kandi gihindure ibara ryacyo. Iyo bihuye na aside hydrochloric ishyushye, biba icyatsi kibisi.
1.7 Imiterere: Uburyo ikoreshwa rya latex na peteroli rikozwemo biterwa n'ubwoko bwa polima irimo. Ibibazo birimo impinduka mbi z'amabara, gutakaza ubworoherane, gutakaza imbaraga zo gukurura no kugabanuka k'ubudahangarwa bw'ingaruka, gusaza, gucikagurika n'ibindi byangiritse ku buso. Antioxydants za peteroli zitanga imikorere n'uburinzi mu bikorwa nka peteroli na pulasitiki, zirinda polima kwangirika kwa oxidative bitewe n'ubushyuhe, urumuri, gucika kwa gaze, peroxide, shear, n'ibindi bintu bihinduka. DPPD antioxydant H itanga ubushyuhe burambye kandi burambye; ikora neza mu bikoresho bya firime, fibre, n'ibice binini; kandi ikora neza mu buryo bwuzuye.

Antioxidant H/DPPD ishobora gukoreshwa nk'ingufu zirinda okisidanti mu icupa rikomeye kugira ngo yongere ubushobozi bwo kubika neza. Yakoreshejwe ku icupa karemano rya styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, polyisoprene kugira ngo rigire imikorere myiza nko kugira ubuzima bwiza bwo guhindagurika no kongera imbaraga mu kongera uburyo bwo gukurura, kongera imbaraga zo kurinda ogisijeni ishyushye, ozone n'ibindi byuma byangiza nk'umuringa, manganese nta ngaruka ku icupa ry'icupa. Ishobora gukemura ikibazo cyo gusaza kiri mu bicuruzwa bya rubber bifite amabara menshi mu gihe antioxidant H ikoreshwa hamwe na antioxidant D. Byongeye kandi, ishobora no gukoreshwa nk'ingufu zirinda ogisijeni ishyushye kuri za pulasitiki nka polyethylene, polypropylene, polyamide, polyformaldehyde kugira ngo yongere ubushobozi bwazo bwo kurwanya ikirere.
Ikoreshwa: 1) Antioxidant H/DPPD (N,N'-Diphenyl-p-phenylenediamine) ikoreshwa nk'irwanya okisidanti no gushimangira ibikomoka ku rubura, amavuta ya peteroli n'ibiryo. Ikoreshwa kandi nk'irinda polymerization no gukumira kwangirika kw'umuringa. Ni igikoresho cy'ubutabire gikoreshwa mu gukora amarangi, imiti, plastiki, n'ibindi bikoresho by'isabune.
2) Antioxidant H/DPPD ikoreshwa kandi mu gukora polyolefini zitagira ibara ndetse na firime za PVC na PVB.
3) Antioxidant H/DPPD ikoreshwa cyane mu bikoresho byinshi bisanzwe n'ibikozwe mu buryo bwa sintetike.
Gupakira:Isakoshi iboshye iriho ishashi ya pulasitiki, ifite uburemere bwa kg 20 ku isashi.
Ububiko:Bibikwa ahantu hakonje kandi hahumeka umwuka. Igihe cyo kubibika ni amezi 12 nyuma y'itariki uwabikoze yatanze. Biracyaboneka niba ibisubizo byo kongera gupimwa byemewe nyuma y'itariki ntarengwa.
Amabwiriza y'umutekano:Uburozi. Uturindantoki twa rubber, uburyo bwo guhumeka n'uburyo bwo kurinda amaso bigomba gukoreshwa mu gihe cyo kubaga mu gihe habayeho gukora ku ruhu cyangwa mu maso.
Ubwikorezi:Irinde imvura, guhura n'ibintu bidasanzwe, ubushyuhe bwinshi.
