Dab tsi yog Brown Fused Alumina

Brown Fused Alumina yog dab tsi?

Brown Fused Alumina, los yog BFA, yog cov khoom zoo, tawv thiab ntse abrasive uas feem ntau siv rau ntau yam kev siv. Nws yog tsim los ntawm high-zoo bauxite thiab coke nyob rau hauv hluav taws xob arc rauv, uas ua rau ib yam khoom uas yog ob qho tib si tawv thiab ruaj.

BFA paub txog nws qhov hardness thiab toughness, ua rau nws zoo tagnrho abrasive khoom rau kev sib tsoo, polishing thiab txiav. Nws kuj yog siv los tsim cov khoom siv refractory, xws li castable refractories, cib thiab cov duab, thiab lwm yam khoom tshwj xeeb xws li cua blasting abrasive thiab precision casting cov ntaub ntawv.

Cov txiaj ntsig tseem ceeb ntawm BFA suav nrog nws qhov siab melting point, uas tso cai rau siv rau hauv cov ntawv thov kub, nws lub siab tawv, uas tso cai rau kev siv txuas ntxiv hauv qhov xav tau ib puag ncig, thiab nws tsis tshua muaj thermal expansion, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cov ntawv thov refractory.

BFANws kuj tseem paub txog nws txoj kev siv ntau yam thiab tuaj yeem siv ntau yam kev siv, suav nrog kev npaj nto, hlau xov, txiav tawm thiab sib tsoo log, polishing, thiab daim ntaub ntawv lapping. Brown Fused Alumina muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab, nrog rau cov nplej, hmoov, thiab cov khoom me me, ua rau nws muaj ntau yam khoom siv uas tuaj yeem kho kom tau raws li kev lag luam tshwj xeeb.

Hauv cov ntsiab lus, Brown Fused Alumina yog cov khoom siv zoo heev uas muaj kev ua haujlwm siab, ua haujlwm ntev, thiab ntau yam. Nws cov khoom tshwj xeeb ua rau nws yog cov khoom siv zoo tshaj plaws rau ntau yam kev siv, suav nrog kev npaj nto, hlau xov, refractory ntau lawm, thiab precision casting.
