COV NTAWV QHIA THIAB COV KHOOM NOJ
nws yog 1: 2 blend ntawm N-1,3-dimethylbutyl-N'-phenyl-p-phenylenediamine (6PPD) thiab N-1,4-dimethylpentyl-N'-phenyl-p-phenylenediamine (7PPD). Ob leeg xaiv cov kev coj ua sib piv. Yog li ntawd, lawv cov quav tshuaj muaj peev xwm suav tau tias yog zoo li 6PPD ntawd kev ua haujlwm nyob rau hauv roj hmab.
nws yog qhia zoo stabilization rau ntau hom tshuaj thiab emulsion polymerized elastomers uas yuav tso tolerate.
Cov khoom muab cov antiozonant haib thiab antioxidant cov khoom uas zoo heev kub flex qaug zog rau cov roj hmab txuas.
nws yog ib qho ua kua hauv chav tsev sov, muab kev ua kom zoo dua cov pa roj carbon dioxide.
nws yog muab kev tiv thaiv compound tiv thaiv catalytic degradation los ntawm tooj liab thiab lwm yam hnyav hlau.
nws tsis muaj cov teebmeem tsis zoo los ntawm cov ntaub ntawv lo rau textiles lossis steel qaum mus txog theem 2 nqe lus. Saum toj no cov concentration nws yuav tawg thiab cuam tshuam nrog lub ply rau lub ply thiab ply rau qaum adhesion.
Nws yuav ua rau lub tebchaw tawg thiab ua rau kev sib cuag ncua thiab kev tsiv teb tsaws.
