Silicon dioxide muaj ntau yam kev siv, thiab cov khoom sib txawv muaj kev siv sib txawv. Ua tus neeg sawv cev zoo rau cov roj hmab hluavtaws, nws qhov kev ua tau zoo yog qhov thib ob tsuas yog carbon dub, thiab zoo dua li carbon dub tom qab kev kho kom zoo thiab tsim nyog. Tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv roj hmab dawb, xim, thiab xim sib dua. Siv ua tus neeg ua kom tuab lossis thickener, tus neeg sawv cev sib xyaw rau cov roj hluavtaws thiab cov xim rwb thaiv tsev, tus neeg sawv cev fading rau cov xim, tus neeg sawv cev thixotropic rau cov khoom siv hluav taws xob ntim khoom, tus neeg ua kom cov hmoov fluorescent thaum lub sijhawm txheej fluorescent screen, tus neeg sau rau cov ntawv luam xim roj hmab, thiab tus neeg sawv cev tso pwm rau casting. Ntxiv nws rau cov resin tuaj yeem txhim kho nws cov dej noo thiab kev ua haujlwm rwb thaiv tsev. Kev sau cov khoom yas tuaj yeem ua rau muaj kev tiv thaiv plam thiab roj. Ntim rau hauv silicone resin, nws tuaj yeem ua rau yas uas tuaj yeem tiv taus qhov kub siab tshaj 200 ℃. Siv ua tus neeg sau thiab cov khoom xyaw nto rau ntawv hauv kev lag luam ntawv.
Cov pa roj carbon dub dawb uas tau ua los ntawm cov roj hmab yog cov khoom siv dav dav rau kev txhawb nqa roj hmab. Feem ntau, vim tias qhov cuam tshuam ntawm cov pa roj carbon dub dawb uas tau ua los ntawm cov roj hmab (tshwj tsis yog ultrafine thiab kev kho saum npoo) tsis zoo npaum li cov pa roj carbon dub, nws yog cov khoom siv semi-reinforced filling. Yog li ntawd, feem pua ​​ntawm cov pa roj carbon dub uas yuav tsum tau hloov yuav tsum tau txiav txim siab raws li qhov xwm txheej siv. Cov pa roj carbon dub dawb uas tau ua los ntawm cov roj hmab siv rau sab hauv thiab sab nraud ntawm cov khoom siv roj hmab xws li tsheb, tsheb thauj khoom pov tseg, tsheb thauj khoom, tsheb laij teb, forklifts, tsheb kauj vab, thiab lwm yam. Nws kuj tseem siv ntau dua lossis tsawg dua hauv ntau yam khoom siv roj hmab xws li siv txoj siv sia, cov yeeb nkab roj hmab, cov ntaub thaiv, cov phaj roj hmab, cov menyuam roj hmab ua cov nplej, thiab cov khau roj hmab. Ntxiv qee qhov ntawm cov pa roj carbon dub dawb rau cov log tsheb ib txwm tuaj yeem txhim kho lawv lub neej kev pabcuam. Raws li kev tshawb fawb thiab cov txiaj ntsig ntawm cov qauv log tsheb ntawm lub tuam txhab West German yav dhau los, ntxiv 10-20 feem ntawm cov pa roj carbon dub dawb tuaj yeem txhim kho qhov nplaum thiab kev tiv thaiv kua muag, ua kom lub log tsheb ntev dua, thiab tseem txhim kho lub log tsheb tuav ntawm txoj kev, uas yog qhov zoo rau kev tsav tsheb nyab xeeb. Ib qho laj thawj uas ua rau Tuam Tshoj lub log tsheb tsis siv roj carbon dub dawb. Tsis tas li ntawd xwb, vim yog lub zog cua sov ntawm cov roj carbon dub, cov log tsheb txawv teb chaws siv rau ntawm txoj kev loj kuj feem ntau ntxiv cov roj carbon dub dawb. Tam sim no, qhov yuav tsum tau ua rau cov log tsheb kauj vab hauv kev lag luam hauv tsev thiab txawv teb chaws muaj ntau yam, xws li cov ntug log tsheb muaj yeeb yuj thiab cov hom tshiab ci ntsa iab, uas tsim los ntawm kev siv cov roj carbon dub dawb es tsis yog cov roj carbon dub. Hauv kev tsim cov khau roj hmab, tib neeg tsis tsuas yog xav tau kev ruaj khov xwb, tab sis kuj xav tau cov xim zoo nkauj, kev nplij siab, thiab lub teeb rau cov khau roj hmab, khau nag, khau kis las, khau mus ncig, khau qoj ib ce, khau ballet, thiab lwm yam. Cov roj carbon dub dawb tsis tsuas yog muaj kev txhawb nqa zoo, kev tiv thaiv kev hnav, kev tiv thaiv kev plam, thiab kev nplaum khau, tab sis kuj yog cov khoom siv txhawb nqa xim zoo. Yog li ntawd, nws ua lub luag haujlwm tseem ceeb hauv kev muab cov khau roj hmab zoo thiab cov qauv hauv kev txhim kho cov khau roj hmab.
Cov pa roj carbon dub dawb siv tau ua cov khoom siv rau hauv cov yas xws li polyethylene, polypropylene, polybutene, thiab epoxy resin, uas tuaj yeem txhim kho lub zog elastic thiab hnav tsis kam ntawm cov yas, nrog rau kev ruaj khov thermal ntawm hardness. Siv rau cov cables, nws kuj tuaj yeem txhim kho lub rwb thaiv tsev hluav taws xob ntawm cov cables. Piv txwv li, methyl vinyl silicone roj hmab high-voltage kab xav tau gas-phase silica lossis high-quality precipitated silica. Nws feem ntau nyuaj rau cais ntawm ob txheej ntawm zaj duab xis yas, thiab nws nyuaj rau qhib lub hnab qhib thaum lub hnab, yog li cov pa roj carbon dub dawb yog tus neeg sawv cev qhib muaj txiaj ntsig zoo heev. Thaum polyvinyl chloride siv ua cov khoom siv hauv pem teb hauv tsev, yog tias ntxiv qee qhov ntawm cov pa roj carbon dub dawb, qhov nyuaj, elasticity, thermal denaturation thiab lwm yam khoom ntawm cov khoom tuaj yeem txhim kho.
Cov pa roj carbon dub dawb siv tau ua cov kua nplaum rau ntawv, uas tuaj yeem txhim kho qhov dawb thiab qhov tsis pom tseeb ntawm daim ntawv, txhim kho kev luam ntawv, tiv taus roj, tiv taus hnav, kov tau tes, thiab ci ntsa iab. Siv rau cov ntawv luam ntawv, nws tuaj yeem ua kom qhov chaw zoo, kua mem ruaj khov, thiab tsis muaj qhov tawg ntawm sab nraub qaum ntawm daim ntawv; Siv rau hauv daim ntawv uas muaj nitrogen, nws tuaj yeem tsim cov duab kos xiav zoo; Siv rau hauv daim ntawv tooj liab ua lwm txoj hauv kev rau titanium dioxide; Tshwj xeeb tshaj yog rau cov ntawv xov xwm, ntxiv 1-2% cov pa roj carbon dub dawb tuaj yeem txo qhov hnyav ntawm daim ntawv los ntawm 10%. Tsis yog daim ntawv nyias xwb, tab sis nws kuj tseem tuaj yeem txhim kho lub zog. Ntxiv nrog rau kev tiv thaiv kev nkag mus ntawm kua mem thiab ua rau cov ntawv luam tawm meej, nws kuj tseem tuaj yeem ua rau qhov tsis pom tseeb ntau ntxiv. Cov pa roj carbon dub dawb muaj cov yam ntxwv thixotropic. Ntxiv me ntsis ntawm cov pa roj carbon dub dawb rau hauv txheej txheej tuaj yeem tshem tawm qhov tshwm sim ntawm cov dej poob. Hauv cov txheej polyester tsis muaj roj, tsuav yog ntxiv 0.5-2% ntawm cov pa roj carbon dub dawb, txheej txheej no tuaj yeem siv rau ntawm qhov chaw ntsug nrog 500g / m2 txhua zaus yam tsis muaj cov dej poob lossis wrinkles.
Ntxiv cov pa roj carbon dub dawb rau cov xim tsis yog tsuas yog tiv thaiv cov xim tsis tau los ntawm kev sib sau ua ke xwb, tab sis kuj txhim kho kev nqus ntawm cov xim thiab cov xim zas, thiab txhim kho kev sib kis. Thaum siv los ua cov khoom siv rau cov txheej emulsion, nws tuaj yeem txhim kho kev ruaj khov thermal. Yuav kom ua tau raws li qhov xav tau ntawm cov txheej thiab cov neeg sawv cev rau cov xim dub dawb, cov khoom tshwj xeeb rau cov neeg sawv cev tau tsim thiab tsim tawm txawv teb chaws. Thaum nitro varnish thiab cov txheej zoo sib xws muaj cov neeg sawv cev rau cov pa roj carbon dub dawb, lawv tuaj yeem txhim kho cov khoom tsis sib sau ua ke ntawm cov xim thiab ua rau cov txheej yooj yim sib cais nrog tsuas yog me me ntawm cov nyhuv tuab, kev ncua zoo, cov khoom zoo heev, pob tshab siab, thiab kev tiv thaiv zoo hnav. Ntxiv 0.5% carbon dub dawb rau cov kua luam ntawv muaj cov nyhuv luam ntawv zoo, tuaj yeem tshem tawm qhov cuam tshuam ntawm cov kua tsis tau sib sau ua ke, txhim kho kev ntxuav tsis kam ntawm cov ntaub ntawv luam ntawv, thiab ua rau cov xim ci ntsa iab.
Tsis tas li ntawd xwb, cov pa roj carbon dawb kuj siv tau rau ntau qib thiab ua ntau yam haujlwm zoo hauv cov tshuaj tua kab, tshuaj, cov nplaum, cov tshuaj txhuam hniav, thiab cov tshuaj pleev ib ce txhua hnub.
