2,2′,5,5′-Tetrachlorobenzidine CAS: 15721-02-5

2,2',5,5'-Tetrachlorobenzidine feem ntau yog siv ua cov xim pleev xim rau kev lag luam, tshwj xeeb tshaj yog hauv kev tsim cov xim pleev xim azo. Cov xim pleev xim no siv dav hauv cov ntaub, ntawv, thiab yas vim lawv cov xim ci ntsa iab thiab cov khoom siv ceev ceev zoo heev. TCB tuaj yeem ua tus neeg sawv cev sib txuas hauv kev tsim ntau yam xim pleev xim, uas yog qhov tseem ceeb rau cov txheej txheem xim hauv kev lag luam textile. Ntxiv rau nws lub luag haujlwm hauv kev tsim cov xim pleev xim, TCB kuj tseem siv rau hauv kev tsim cov xim thiab cov txheej txheem pleev xim. Cov tshuaj chlorine hloov pauv ntawm cov tshuaj ua rau nws ruaj khov thiab cov khoom xim, ua rau nws haum rau cov ntawv thov uas xav tau cov xim zoo, xws li hauv kev ua tiav tsheb thiab cov txheej txheem pleev xim rau kev lag luam. Ntxiv mus, TCB tau raug tshawb fawb txog nws qhov kev siv tau hauv kev siv hluav taws xob, ua tus ua ntej rau kev coj cov polymers thiab cov ntaub ntawv. Nws cov qauv molecular tshwj xeeb tso cai rau kev hloov kho uas tuaj yeem txhim kho cov khoom ntawm cov polymers no, ua rau lawv haum rau cov khoom siv hluav taws xob. Txawm hais tias nws muaj txiaj ntsig zoo los xij, nws yog ib qho tseem ceeb uas yuav tsum ceev faj thaum siv 2,2', 5,5'-Tetrachlorobenzidine, vim nws tau raug cais ua ib yam khoom txaus ntshai. Kev raug TCB tuaj yeem ua rau muaj kev pheej hmoo rau kev noj qab haus huv, suav nrog cov teebmeem carcinogen, uas yuav tsum muaj cov kev cai tswjfwm nruj thiab cov txheej txheem kev nyab xeeb hauv kev siv hauv kev lag luam. Kev cuam tshuam rau ib puag ncig ntawm TCB thiab nws cov khoom puas tsuaj kuj xav tau kev txiav txim siab zoo, txhawb kev xav tau lwm txoj hauv kev nyab xeeb dua thiab kev txhim kho kev tswj hwm pov tseg hauv kev lag luam siv cov tshuaj no.
