1.Cov txheej txheem kev lag luam lub ntsiab lus
Lub lim tiam no, tus nqi ntawm cov ntshiab benzene tseem nyob ruaj khov thaum uas ntawm aniline nce siab me ntsis, tab sis nyob rau lub sijhawm luv luv tsis muaj lub zog nce ntxiv los tswj cov hluav taws xob tsawg. Lwm cov ntaub ntawv raw, xws li MIBK, carbon disulfide, acetone, cyclohexylamine thiab tert-butylamine, qhov pib ruaj khov.
Tus leeb yuav tswj hwm lub xeev kom ruaj khov nyob rau lub asthiv no. Vim tias qib qis ntawm aniline, cov khoom siv yooj yim, thiab tsis muaj lub hauv paus rau kev nce nqi ntawm tus tsuj roj, ua raws cov nqi tau pib nyob rau qib tam sim no. Nyob ze yav tom ntej, kev tsim tawm ntawm kev nrawm nrawm kuj tseem ruaj khov, tsuas yog qee cov khoom lag luam, theem pib sib npaug ntawm cov khoom siv thiab xav tau.
Tus nqi ntawm cov neeg sawv cev tiv thaiv kev laus tsis tau hloov lub lim tiam no, tab sis cov khoom tseem nruj, thiab qhov tshwm sim ntawm lub Hoobkas ua haujlwm rau cov zaub mov xa tuaj tseem muaj. Kev tshuaj ntsuam lub teb chaws ntawm nitrobenzene ntau lawm tsis tiav, thiab muaj qee yam tsis paub tseeb nyob rau hauv kev ruaj khov ntawm cov khoom siv, yog li nws yog ib ntus txiav txim siab tias tus nqi ntawm cov neeg ua hauj lwm tiv thaiv kev laus yuav nyob zoo.
Cov khoom ntawm insoluble sulfur thiab zinc oxide yog rov qab ntau dua, cov khoom lag luam raug cuam tshuam los ntawm tus nqi, cov nqi yog qhov pib ruaj khov, thiab cov nyiaj tau los yog hauv lub xeev tsim nyog.
