Dab tsi yog carbon dub?

Cov pa roj carbon dub, yog ib qho amorphous carbon, lub teeb, xoob thiab zoo heev dub hmoov, uas tuaj yeem nkag siab zoo li hauv qab ntawm lub lauj kaub.

Nws yog ib yam khoom uas tau los ntawm kev ua tsis tiav los yog thermal decomposition ntawm carbonaceous tshuaj xws li thee, natural gas, hnyav roj, thiab roj roj nyob rau hauv cov huab cua tsis txaus.


Carbon Black


Lub ntsiab tseem ceeb ntawm cov pa roj carbon dub yog cov pa roj carbon, uas yog qhov ntxov tshaj plaws nanomaterial tsim, siv thiab tam sim no tsim los ntawm noob neej. , yog teev raws li ib qho ntawm nees nkaum tsib cov khoom siv tshuaj lom neeg thiab cov khoom siv tshuaj zoo los ntawm kev lag luam tshuaj lom neeg thoob ntiaj teb.

Kev lag luam carbon dub yog qhov tseem ceeb heev rau kev lag luam log tsheb, kev lag luam dyeing thiab txhim kho cov khoom zoo ntawm pej xeem lub neej.



Qhov thib ob, kev faib cov pa roj carbon dub

1. Raws li kev tsim khoom

Feem ntau muab faib ua lub teeb dub, roj dub, rauv dub thiab qhov dub.


2. Raws li lub hom phiaj

Raws li kev siv sib txawv, carbon dub feem ntau muab faib ua carbon dub rau xim, carbon dub rau roj hmab, conductive carbon dub thiab tshwj xeeb carbon dub.


Cov pa roj carbon dub rau cov xim - Thoob ntiaj teb, raws li cov xim muaj peev xwm ntawm cov xim dub, nws feem ntau muab faib ua peb pawg, uas yog cov xim xim carbon dub, nruab nrab cov xim carbon dub thiab cov xim tsis tshua muaj xim carbon dub.

Qhov kev faib tawm no feem ntau yog sawv cev los ntawm peb tsab ntawv Askiv, thawj ob tsab ntawv qhia txog cov xim muaj peev xwm ntawm cov xim dub, thiab tsab ntawv kawg qhia txog kev tsim khoom.


3. Raws li kev ua haujlwm

Feem ntau muab faib ua cov pa roj carbon ntxiv, cov xim carbon dub, cov pa roj carbon dub, thiab lwm yam.


4. Raws li tus qauv

Feem ntau muab faib ua N220,


Daim ntawv thov hauv kev lag luam roj hmab

Cov pa roj carbon dub siv hauv kev lag luam roj hmab suav rau ntau dua 90% ntawm tag nrho cov pa roj carbon dub tso tawm. Feem ntau yog siv rau ntau hom log tsheb, xws li tsheb log tsheb, tsheb laij teb, tsheb log tsheb, lub zog tsheb log tsheb, tsheb kauj vab log tsheb, thiab lwm yam. Txog 10 kilograms ntawm carbon dub yog xav tau los tsim cov log tsheb zoo tib yam.


Nyob rau hauv cov pa roj carbon dub rau roj hmab, ntau tshaj peb-plaub ntawm cov pa roj carbon dub yog siv rau hauv kev tsim cov log tsheb, thiab cov seem yog siv rau hauv lwm cov khoom siv roj hmab, xws li tapes, hoses, khau roj hmab, thiab lwm yam hauv cov khoom siv roj hmab. , kev noj cov roj carbon dub suav txog li 40 ~ 50% ntawm kev siv roj hmab.


Yog vim li cas vim li cas carbon dub siv ntau heev hauv roj hmab yog nws zoo heev thiaj li hu ua "txhim kho" muaj peev xwm. Qhov "txhim kho" muaj peev xwm ntawm carbon dub tau pom thawj zaug hauv cov roj hmab ntuj thaum ntxov li xyoo 1914. Tam sim no tau lees paub tias rau cov roj hmab hluavtaws, lub peev xwm txhawb nqa cov pa roj carbon dub ua lub luag haujlwm tseem ceeb dua.


Lub cim tseem ceeb tshaj plaws ntawm cov pa roj carbon dub yog txhawm rau txhim kho kev hnav ntawm lub log tsheb. Lub log tsheb nrog 30% cov pa roj carbon ntxiv tuaj yeem taug kev 48,000 txog 64,000 mais; thaum sau tib tus nqi ntawm inert los yog tsis muaj zog muab tub lim es tsis txhob carbon Black, nws mileage tsuas yog 4800 kilometers.


Tsis tas li ntawd, cov pa roj carbon muaj zog ntxiv tuaj yeem txhim kho lub cev thiab lub zog ntawm cov khoom siv roj hmab, xws li lub zog tensile thiab lub zog tsim kua muag. Piv txwv li, ntxiv cov roj carbon dub ntxiv rau cov roj hmab crystalline xws li roj hmab ntuj lossis neoprene tuaj yeem ua rau lub zog tensile los ntawm 1 txog 1.7 npaug piv rau cov roj hmab vulcanized yam tsis muaj carbon dub; Hauv cov roj hmab, nws tuaj yeem nce mus txog li 4 mus rau 12 zaug.


Hauv kev lag luam roj hmab, hom carbon dub thiab nws cov nqi sib xyaw yuav tsum tau txiav txim siab raws li lub hom phiaj thiab kev siv ntawm cov khoom. Piv txwv li, rau cov log tsheb treads, hnav tsis kam yuav tsum tau txiav txim siab ua ntej, yog li cov pa roj carbon ntau ntxiv, xws li ultra-abrasion-resistant furnace dub, nruab nrab-siab hnav-resistant rauv dub lossis high-abrasion-resistant furnace dub, yuav tsum tau. ; thaum tread thiab carcass roj hmab Cov khoom yuav tsum tau carbon dub nrog yam tsawg kawg nkaus hysteresis poob thiab tsawg tshav kub tiam.
