Kana tsika yechinyakare inorwisa Antioxidant yekufonera neiyo nitrogen gasi uye okisijeni gasi mumhepo, inoburitsa quinone chimiro. Qinone chimiro ndiwo mudzi wakakonzera yero uye kuwana tsvuku.
Phosphite antioxidant inoshandiswawo zvakanyanya sechibereko chakanakisa chebetsoxident. Nekudaro, nekuenderera mberi kwekuvandudzwa kweEU zvakaringana zvidziviriro zviyero, izvo zvinodikanwa zveNhosph Atioxidant vari kuve vakakwira uye vakakwira. Phosph a Atioxidant inoda kuve zvakanyanya kushamwaridzana, isina-chepfu, isiri-phenolol, hydrolysis inopesana, uye kuramba kupisa kwakanyanya.
Phosphite auxiliary antioxidant ndeimwe yeanonyanya kushanda polymer stillmer anowedzera mu1990. Mumakore gumi, marudzi matsva emarudzi anobuda mukusingaperi, asi nezvemakemikari zvacho, isu tinogona kuwana chimiro chetsva chePhosphite chinorira, uye zvakanyanya pentaerthritol Zvinoreva kuti phososhate ester autoxidant tekinoroji yekuvandudza kusimudzira kwezvinhu zviviri zvinofanirwa kutarisa zvikamu zviviri: Maitiro ekuvandudza kugadzikana kwemununiso uye maitiro ekuvandudza hydrolytic kugadzikana.
Yedu isiri-phenolic antioxidant -an3333334 & An340, haina chimiro chakatsunga, saka inogona kudzivisa zvinobudirira dambudziko reyero rakakonzerwa neQinone chimiro. Iyo tembiricha yekudzidzira inogona kunge iri pamusoro 180 ℃, uye yakaiswa muPu, PVC uye mamwe minda nevatengi vazhinji mukati uye kunze kwenyika.
Pakati pavo, An333 aratidzwa kuti aite zvakanakisa muzvinhu zvekupupuma, aine yakanakisa yellowing kuramba uye yakanaka hydrolysis kuramba. Ndiwo akanakisa kutsiva kwaJohoku makemikari jp333e.
Kunze kweiyo isiri-phenol antioxidants, isu tinopawo zvimwe zvinowedzera zvinoshandiswa muPU application. Pazasi zvigadzirwa ndezvekusarudza kwako:
