Carbon black: ib qhov khoom siv ntau yam uas muaj liaj ua kev hauv tshuab tsoom

Carbon black yog ib qhov zaum npuab ntawm cov khoom sisaub tshaj tig hluas. Vim nws muaj qhov kev sib txawv hauv kev tshawb fawb thiab kev tshawb xav, nws tau ntxiv mus ua ib qho khoom tsis kam ceeb rau kev lag luam hauv cheeb tsheb no. Nws muaj ntau yam kev siv, los ntawm yam khoom siv hauv hnub hli mus rau lub sijhawm siv kev tshaj lij, thiab ua ib qho cheeb tsheb tseem ceeb.

Nyob hauv qhov chaw ua zib, carbon black yog thawj yam khoom siv rau kev ua ntoo hlau. Nws tuaj yeem pab txhim kho qhov ceev, txhim kho qhov tshem tshem thiab qhov tshem tshem ntawm zib, ntxiv sijhawm siv ntawm ntoo hlau thiab pab txhim kho qhov kev ua haujlwm. Txog li cas li, nyob hauv lub ntiaj teb, muaj feem ntau ntawm cov carbon black (70%) siv hauv kev tsim ntoo hlau thiab lwm yam khoom zib.

Hauv cheeb tsam ntawm cov khoom siv plastic, carbon black tsis yog ib tug li siv los ua liab dub, xwb tab sis kuj pab tiv thaiv kev cuam tshuam los ntawm dej nkhaus thiab tiv thaiv khoom tsis txhob yooj yav. Qhov txaus siab tias nws muaj kev sib cuag kuj siv rau cov khoom siv plastic uas muaj kev sib cuag lossis tsis muaj kev sib cuag, xws li cov khoom siv rau rooj kawg, khw nplooj thiab lwm yam. Tom qab ntawd, qhov chaw ua ink thiab ua coating kuj tseem tshua siv carbon black los muab liab dub zoo, uas pom tau hauv tus npleev, tus npeev ntawv, ua siab ntawm lub ru taub, thiab ua siab rau tsev.

Zoo li kev pab cuam tshwm ntej ntawm kev tshauv npe, qhov siv ntawm carbon black tseem tab tom nce ntau dua. Nyob hauv cheeb tsam ntawm tshuaj tshiab, nws yog siv los ua thawj kem tshuaj tshiab rau lithium ion batteries; nyob hauv cheeb tsam ntawm kev tswj hwm dej noj mov, carbon black tau suab ntxiv los tshem tawm cov tshuaj tiv thaiv nyuj yaj nyob hauv dej. Qhov chaw sib ntxig ntawm nws kuj siv ntau hauv kev tshauv npe zoo li kev tshem tawm kev ntxuav ntawm cov khoom siv hluav taws khib thiab kev tshem tawm kev ntxuav electromagnetic.

Raw li ib qho piv txwv tseem ceeb ntawm kev siv khoom siv nyob rau tseem ceeb, carbon black tau tsim los ntawm coal tar lossis ethylene cracking tail gas, uas tsis yog tsuas yog muaj nyiaj zoo xwb, tab sis kuj muaj kev ua haujlwm zoo. Tom ntej, nyob rau hauv kev pab cuam ntawm nanotechnology, carbon black yuav tso cai rau nws nyob hauv qhov chaw tshiab zoo li flexible electronics thiab smart materials, thiab yuav tseem ceeb tshaj plaws rau nws qhov chaw nyob hauv tsev lag luam li "black gold".
