CHEMICAL NAME:N-(1,3-dimethylbutyl)-N'-phenyl –p –phenylenediamine 6PPD
CAS Nr .:793-24-8
Rubber antioxidant 6PPD yog ib qho antioxidant thiab tiv thaiv -oxidizing tus neeg sawv cev dav siv hauv cov log tsheb roj hmab. Nws yog nyob rau hauv chav kawm ntawm roj hmab additives hu ua para-phenylenediamine. Nws muaj feem xyuam rau ob qho tib si roj hmab thiab hluavtaws roj hmab thiab tuaj yeem ua kom ntev kev pab cuam lub neej ntawm cov khoom siv roj hmab xws li cov log tsheb. Nws suav txog kwv yees li 55% ntawm kev lag luam antioxidant hauv Suav teb. Txawm li cas los xij, 6PPD yuav hloov mus rau hauv cov khoom muaj tshuaj lom, 6PPD-quinone, nyob rau hauv ib puag ncig (xws li los ntawm ozone oxidation, photolysis, lossis hauv av). Cov tshuaj no muaj cov tshuaj toxicity siab heev rau cov kab mob hauv dej thiab yuav ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv, uas tau ua rau muaj kev cuam tshuam thoob plaws hauv thaj chaw ntawm ib puag ncig thiab kev noj qab haus huv.
