Antioxidant H CAS 74-31-7 Antioxidant DPPD
Dzina lachingerezi:N, N-diphenyl-p-phenylenediamine
Chidule cha Chingerezi:DPPD
CAS RN:74-31-7
1. Thupi ndi mankhwala:
1.1 Chilinganizo cha maselo: C18H16N2
1.2 Kulemera kwa mamolekyu: 260.34
1.3 Mphamvu yokoka yeniyeni: 1.2
1.4 Kusungunuka: Sungunulani mu benzene, ether ndi acetone. Sungunulani pang'ono mu Mowa. Zosasungunuka m'madzi.
1.5 Kuwira: 220-225 ℃, 0.5mmHg
1.6 Kukhazikika ndi kuyambiranso: Kuwotcha. Ikayatsidwa ndi mpweya kapena kuwala kwa dzuwa, mankhwalawa amakhala okosijeni ndikusintha mtundu wake. Mukakumana ndi hydrochloric acid yotentha, imakhala yobiriwira.
1.7 Katundu: Makutidwe ndi okosijeni a zinthu za latex ndi labala zimatengera mtundu wa polima womwe ukukhudzidwa. Mavuto akuphatikizapo kusintha kwa mtundu, kutayika kwa kusinthasintha, kutaya mphamvu zowonongeka ndi kuchepa kwa mphamvu, kukalamba, kusweka ndi kuwonongeka kwina. Ma antioxidants amphira amapereka magwiridwe antchito komanso chitetezo chofunikira pamagwiritsidwe ntchito monga mphira ndi mapulasitiki, kuteteza ma polima kuti asawonongeke chifukwa cha kutentha, kuwala, kuzimiririka kwa gasi, peroxides, kumeta ubweya ndi zinthu zina zamphamvu. DPPD antioxidant H imapereka kukhazikika kwa kutentha kwanthawi yayitali komanso kukhazikika kwamtundu; imakhala yogwira mtima mufilimu, ulusi, ndi zolemba zapakatikati; ndipo imachita bwino pamakina odzaza.

Antioxidant H / DPPD ingagwiritsidwe ntchito ngati antioxidant mu propellant yolimba kuti apititse patsogolo kukhazikika kosungirako kwa mankhwala. Zakhala zikugwiritsidwa ntchito kwa anthu achilengedwe, styrene-butadiene, acrylonitrile-butadiene, butadiene, butyl, hydroxyl, mphira wa polyisoprene kuti akhale ndi magwiridwe antchito monga moyo wabwino wosinthika komanso kulakalaka kupititsa patsogolo mphamvu yamagetsi, kulimbitsa ntchito yoteteza mpweya wotentha, ozoni. ndi zitsulo zina zovulaza monga mkuwa, manganese zomwe sizimakhudza kuwonongeka kwa mphirawo. Ikhoza kuthetsa vuto la ukalamba lomwe lilipo muzinthu zamtundu wa rabara pamene antioxidant H imagwiritsidwa ntchito pamodzi ndi antioxidant D. Komanso, itha kugwiritsidwanso ntchito ngati stabilizer yotentha ya okosijeni kwa mapulasitiki a uinjiniya monga polyethylene, polypropylene, polyamide, polyformaldehyde mpaka kupititsa patsogolo ntchito yawo yolimbana ndi nyengo.
Gwiritsani ntchito: 1) Antioxidant H / DPPD (N, N'-Diphenyl-p-phenylenediamine) imagwiritsidwa ntchito ngati antioxidant ndi stabilizer kwa mphira, mafuta a petroleum ndi zakudya. Amagwiritsidwanso ntchito ngati polymerization inhibitor komanso retardant motsutsana ndi kuwonongeka kwa mkuwa. Ndi mankhwala apakatikati opangira utoto, mankhwala, mapulasitiki, ndi zowonjezera zotsukira.
2) Antioxidant H/DPPD imagwiritsidwanso ntchito popanga ma polyolefin okhazikika opanda mtundu komanso mafilimu a PVC ndi PVB.
3) Antioxidant H / DPPD imagwiritsidwa ntchito kwambiri m'ma lattices achilengedwe komanso opangidwa ndi ma rubber.
Kulongedza:Thumba loluka lokhala ndi thumba la pulasitiki, lolemera 20 kg/thumba.
Posungira: Kusungidwa mu ozizira, mpweya wokwanira malo. Nthawi ya alumali ndi miyezi 12 kuchokera tsiku la wopanga. Ikupezekabe ngati zotsatira zoyesanso ziyeneretsedwa tsiku lomaliza ntchito
Malangizo achitetezo: Zapoizoni. Magolovesi amphira, zopumira komanso chitetezo cha maso ziyenera kugwiritsidwa ntchito pokhudzana ndi khungu, kukhudzana ndi maso.
Mayendedwe:Pewani mvula, kukhudzana, kutentha kwambiri.
