PCB kuj tseem yog lub rooj sib tham luam tawm, yog cov khoom siv hluav taws xob tseem ceeb dua, cov khoom siv hluav taws xob ntawm lub cev txhawb nqa. Muaj qee tus phooj ywg hauv daim duab teeb duab, tsis paub tias txheej txheem PCB tsis zoo thiab txheej txheem zoo li cas, xiaobian hauv qab no rau koj los qhia PCB cov txheej txheem tsis zoo thiab txheej txheem zoo.

Cov txheej txheem PCB tsis zoo thiab zoo qhia qhov cuam tshuam ntawm kev tsim khoom.

PCB tsis zoo thev naus laus zis thiab thev naus laus zis zoo

Cov txheej txheem zoo

Kev tsim cov yeeb yaj kiab tshwj xeeb feem ntau tsis muaj tooj liab, nrog tooj liab khaws cia rau hauv qhov thaiv thiab tooj liab tso rau thaj chaw, thiab tsis muaj kev txwv tooj liab hauv qhov txuas thiab tooj liab tso. Piv txwv, txheej txheej ntawm txheej txheej saum toj kawg nkaus, txheej hauv qab thiab lwm yam yog qhov zoo.

Cov txheej txheem zoo yog cov laj thawj rau yav tom ntej, qhov ua yuam kev yog me me, vim tias cov txheej txheem zoo tau txais txoj hauv kev los ntxiv cov tooj liab uas muaj zog, hauv paus tuaj yeem ua tau raws li txhua qhov kev tsim qauv, tshwj tsis yog lub rooj tsav xwm yuav tsim yog nyuaj heev, yog li nws zoo dua los siv zoo rau tsim PCB, tshwj xeeb yog cov novice.

Cov txheej txheem tsis zoo

Cov txheej txheem tsis zoo yog qhov tsis zoo ntawm cov txheej txheem zoo. Cov txheej txheem tsis zoo muaj tooj liab los ntawm lub neej ntawd. Tsis muaj tooj liab nyob hauv thaj chaw thaiv thiab tooj liab, thiab muaj tooj liab tshwj tseg hauv thaj chaw uas tsis muaj kab thiab tooj liab. Qhia meej yog tias txheej txheem tsis zoo yuav siv.

Cov txheej txheem tsis zoo yog me ntsis yooj yim dua li cov txheej txheem zoo, qhov uas koj tsuas yog hais qhia qhov twg koj tsis xav tau tooj liab, qhov txheej txheem zoo xav kom koj kos tooj liab hauv daim.
