Roj Hmab Antioxidant TMQ yog qee yam tshuaj polyurethane ua npuas yas xws li cov hluav taws kub npau npau loj, microporous elastomer thiab ib nrab npau npau yog ib qho siv ntau ntxiv, xws li txhim kho thiab kho cov kev ua haujlwm ntawm polyurethane ua npuas yas muaj cov nyhuv loj heev. Nyob rau hauv txoj kev lag luam plastics, Rubber Antioxidant TMQ yog siv hauv epoxy reintegration, unsaturated polymer, phenolic aldehyde, polyethylene, polyvinyl chloride thiab lwm yam plastics.
Feem ntau siv Rubber Antioxidant tmq muaj xws li imidazole Rubber Antioxidant tmq, benzoic anhydride, diethylenetriamine, tert-butylperoxy ethane, hexamethylenetetramine, thiab lwm yam.
Roj Hmab Antioxidant tmq yog cov kab mob feem ntau yog hydrogen tebchaw uas muaj ntau hom kev ua haujlwm, xws li polyols thiab polyamines nrog cov me me ntawm molecular phaus. Polyols muaj cov amino thiab atrial nitrogen atoms kuj siv tau los ua Rubber Antioxidant tmq.
Lawv kuj catalyze cov tshuaj tiv thaiv ntawm isocyanate thiab polyol. Cov piv txwv muaj xws li ethanolamine, di-2-phenylamine, triethanolamine, thiab alkyl derivatives of piperazine. Triethanolamine, diethanolamine thiab lwm cov tshuaj alkanolamine yog ib txwm siv los ua antioxidants rau cov roj ua kom muaj zog thiab ua rau lub nruab nrab ntawm lub cev muaj zog. Nrog qhib lub me me molecule polyhydric cawv los yog cawv amine tus neeg ua hauj lwm thiab oxidation ntawm ethylene polymerization thiab qhov sib txawv ntawm molecular ntawm lub viscosity tsawg ntawm 175,000 polyols yuav siv li ib lub mis, xws li RIM ib nrab npuas nrog aniline thiab toluene diamine nrog ethylene oxide sib ntxiv ntawm tsis tshua muaj molecular nyhav thiab high aromatic polyols ua si, kuj siv tau rau kev tshawb fawb hauv tsab ntawv tsa suab (RIM) microporous elastomer thiab semi-rigid npuas mis, thiab lwm yam.
Tshuaj ntxiv ib Rubber Antioxidant TMQ lub hom phiaj yog ua kom muaj linear macromolecule los yog branched saw ntawm cov qauv kev sib dhos ntawm cov kabmob crosslinking molecules, uas ua rau cov qauv txhuam molecular los ntawm txoj kab rau cov kab hom lossis loj ntawm cov qauv molecular, thiab hloov lub cev thiab cov khoom siv dag zog ntawm cov yas thiab yas yaj rheological thaj chaw.
Feem ntau, nyob rau hauv tus txheej txheem ntawm cov yas ua haujlwm crosslinked polymer yog qhov chaw ua haujlwm ntawm cov tshuaj tiv thaiv macromolecular, cov kev ua haujlwm hauv lub cev los sis lub chaw ua haujlwm, los yog cov chaw kho mob thiab Rubber Antioxidant TMQ nug kom teb. Cov chaw ua haujlwm no muaj peev xwm muab tau cov tshuaj tiv thaiv ua ke, hauv qee qhov xwm txheej, xws li pib los yog muaj cov catalyst, tuaj yeem ua rau cov tshuaj molecules ua qhov kev sib tawm tsam, ua cov qauv zoo.
