Cov pa roj carbon dub dawb yog ua los ntawm nano silica, nrog rau cov khoom huv huv txog li 99% thiab qhov loj me ntawm cov khoom me me yog 10-20 nm. Txawm li cas los xij, cov txheej txheem npaj khoom yog qhov nyuaj thiab kim heev; Cov pa roj carbon dub dawb uas tau tawg ua tej daim muaj cov khoom me me uas tau tawg ua tej daim thiab cov pa roj carbon dub uas tau tawg ua tej daim. Cov qub hais txog silicon dioxide uas tsim los ntawm sulfuric acid, hydrochloric acid, CO2 thiab dej iav ua cov khoom siv raw, thiab cov tom kawg hais txog silicon dioxide uas tsim los ntawm cov txheej txheem tshwj xeeb xws li kev siv tshuab hnyav siab, txoj kev sol gel, txoj kev siv tshuaj siv lead ua, txoj kev crystallization theem ob lossis txoj kev reverse micellar micro lotion. Cov silica uas tau tawg ua tej daim feem ntau yog siv los ua tus neeg sawv cev rau cov roj hmab ntuj thiab cov roj hmab hluavtaws, nrog rau tus neeg sawv cev rau kev sib txhuam rau cov tshuaj txhuam hniav. Cov kua roj hmab vapor phase feem ntau yog siv los ua tus neeg sawv cev txhawb nqa, txheej thiab cov khoom siv tsis muaj zog ntawm cov roj hmab silicone, thiab cov kua roj hmab zoo heev thiab cov roj hmab airgel feem ntau yog siv los ua tus neeg sawv cev matting, thickener, tus neeg sawv cev qhib yas zaj duab xis, thiab lwm yam. Raws li cov khoom siv zoo rau ib puag ncig thiab muaj kev ua tau zoo, cov pa roj carbon dawb feem ntau yog siv rau hauv cov khoom siv roj hmab (xws li cov roj hmab silicone kub siab), cov ntaub, kev ua ntawv, cov tshuaj tua kab, thiab cov khoom noj khoom haus ntxiv.

Kev Siv:

Cov khoom siv roj hmab

Cov pa roj carbon dub dawb yog siv rau hauv cov khoom siv roj hmab xim los hloov cov pa roj carbon dub rau kev txhawb nqa, ua tau raws li qhov xav tau ntawm cov khoom dawb lossis semi-pob tshab. Silica kuj muaj kev nplaum zoo heev, tiv taus kua muag, tiv taus kub thiab tiv taus kev laus, yog li nws kuj tuaj yeem hloov ib feem ntawm cov pa roj carbon dub hauv cov khoom siv roj hmab dub kom tau txais cov khoom siv roj hmab zoo, xws li cov log tsheb off-road, cov log tsheb engineering, cov log tsheb radial, thiab lwm yam.

Cov khoom siv tshuaj lom neeg txhua hnub

Cov tshuaj txhuam hniav muaj xim pob tshab thiab tsis pom tseeb nrog cov pa roj carbon dawb ua cov khoom sau thiab cov khoom siv abrasive, uas muaj kev ywj pheej zoo thiab kev sib kis tau zoo, du thiab mos nplaum, tiv taus kev sib txhuam zoo, thiab tsis ua rau lub raj tshuaj txhuam hniav xeb; Nws tuaj yeem tswj tau qhov ruaj khov ntawm cov tshuaj txhuam hniav. Tshwj xeeb tshaj yog nrog kev sib raug zoo nrog fluoride, nws tuaj yeem zam qhov tsis zoo ntawm cov ntsev tsis yaj uas tsim los ntawm cov ntsev calcium ua cov khoom siv abrasive.

Tus neeg sawv cev cementing

Siv rau hauv cov nplaum ua los ntawm roj hmab ntuj lossis roj hmab hluavtaws, nws muab thixotropy thiab kev txhawb zog, thaum tseem txhim kho kev nplaum vim nws txoj kev ncab, ua rau nws zoo thiab tsim nyog tus nqi.

Tus neeg sawv cev tiv thaiv kev sib sau ua ke

Cov pa roj carbon dawb siv tau rau hauv qee yam khoom kom txhim kho kev ua haujlwm dawb, xws li cov chiv nyom, cov tshuaj tua kab mob, cov khoom sib tsoo log, cov tshuaj ntxhua khaub ncaws, phenolic txhaj tshuaj molding ntawm urotropine, cov khoom yas ntawm phenols thiab urea, kev tsim cov roj hmab sulfur thiab cov khoom sib xyaw tiv thaiv kev sib sau ua ke.

Kev sau ntawv

Siv cov pa roj carbon dub dawb ua cov khoom siv rau hauv daim ntawv tuaj yeem ua rau daim ntawv tsis kam tiv taus cov kua mem thiab lub zog kho tshuab zoo dua, ua rau dawb dua, thiab txo qhov hnyav ntawm daim ntawv. Nws tuaj yeem ua rau daim ntawv sib dua, txo cov nqi tsim khoom, thiab txhim kho kev ua haujlwm ntawm daim ntawv.

Tsis tas li ntawd xwb, nws kuj siv tau rau ntau yam lag luam xws li cov neeg ua hluav taws, pub zaub mov, tshuaj pleev ib ce, cov neeg ua kom ploj mus, cov xim, xim pleev xim, thiab lwm yam.
