Siv Fields
Dyeing
Cov tshuaj no yog ib hom plaub hau zas plaub hau. Nws siv yog hloov los ntawm lwm cov aniline analogues thiab derivatives xws li 2,5-diamino (hydroxyethylbenzene thiab 2,5-diaminotoluene. Lwm cov derivatives nrov muaj xws li tetraaminopyrimidine thiab indoanilines thiab indophenols. qhov ze li ntawm cov xim tsis muaj xim ua ntej oxidizes rau cov xim.
Precursor rau polymers
PPD yog lub hauv paus rau aramid plastics thiab fibers xws li Kevlar. Cov ntawv thov no siv PPD qhov kev ua haujlwm tsis zoo. Cov polymer no tshwm sim los ntawm cov tshuaj tiv thaiv ntawm PPD thiab terephthaloyl chloride. Cov tshuaj tiv thaiv ntawm PPD nrog phosgene muab cov diisocyanate, ua ntej rau urethane polymers.
Roj hmab antioxidant
PPD yog yooj yim oxidized, thiab vim li no derivatives ntawm PPD yog siv asantiozonants hauv zus tau tej cov khoom roj hmab. Cov tshuaj hloov pauv, naphthyl, isopropyl thiab lwm yam cuam tshuam rau kev ua haujlwm ntawm lawv lub luag haujlwm antioxidant nrog rau lawv cov khoom raws li cov tawv nqaij khaus.
