Qhov nyuaj tshaj plaws blasting nruab nrab silicon carbide grit

Junda silicon carbide grit yog qhov nyuaj tshaj plaws blasting media muaj. Cov khoom lag luam zoo no yog tsim kom muaj rau lub blocky, cov duab angular. Cov xov xwm no yuav tawg tsis tu ncua ua rau muaj cov npoo ntse, txiav cov npoo. Lub hardness ntawm silicon carbide grit tso cai rau luv luv lub sij hawm tua lub sij hawm txheeb ze rau softer medias.

Vim nws cov tshuaj ruaj khov, siab thermal conductivity, qis thermal nthuav tawm cov coefficient, thiab cov khoom zoo li silicon muaj ntau lwm yam kev siv ua cov khoom siv abrasives. Piv txwv li, silicon carbide hmoov yog thov rau impeller lossis kheej kheej ntawm cov dej turbine los ntawm cov txheej txheem tshwj xeeb. Sab hauv phab ntsa tuaj yeem txhim kho nws cov hnav tsis kam thiab muaj lub neej ua haujlwm ntev los ntawm 1 txog 2 zaug; Cov khoom siv hluav taws xob siab ua los ntawm nws muaj cua sov tsis kam, qhov hnyav me, lub zog muaj zog thiab txuag lub zog zoo. Low-qib silicon carbide (muaj txog 85% ntawm sic) yog ib qho deoxidization zoo heev. Nws tuaj yeem ceev cov steelmaking ceev, thiab pab txhawb kev tswj hwm cov tshuaj muaj pes tsawg leeg tshuaj thiab txhim kho cov hlau zoo. Tsis tas li ntawd, Silicon Carbide tseem dav siv los ua Silicon Carbide pas nrig rau hluav taws xob cua sov.

Silicon carbide muaj qhov nyuaj li silic muaj lub hardness heev, nrog mohs hardness ntawm 9.5, thib ob tsuas yog rau lub ntiaj teb nyuaj tshaj plaws pob zeb diamond (10). Nws muaj cov thermal zoo heev, yog semiconductor, thiab tuaj yeem tawm tsam oxidation thaum kub.

Vim nws cov tshuaj ruaj khov, siab thermal conductivity, qis thermal nthuav tawm cov coefficient, thiab cov khoom zoo li silicon muaj ntau lwm yam kev siv ua cov khoom siv abrasives. Piv txwv li, silicon carbide hmoov yog thov rau impeller lossis kheej kheej ntawm cov dej turbine los ntawm cov txheej txheem tshwj xeeb. Sab hauv phab ntsa tuaj yeem nce nws cov hnav tsis kam thiab muaj lub neej ua haujlwm ntev los ntawm 1 txog 2 zaug; Cov khoom siv refractory ua los ntawm nws muaj cua sov tsis kam, loj me me, lub teeb yuag, siab lub zog txuag cov nyhuv. Low-qib silicon carbide (muaj txog 85% ntawm sic) yog ib qho deoxidization zoo heev. Nws tuaj yeem ceev cov steelmaking ceev, thiab pab txhawb kev tswj hwm cov tshuaj muaj pes tsawg leeg tshuaj thiab txhim kho cov hlau zoo. Tsis tas li ntawd, Silicon Carbide tseem dav siv los ua Silicon Carbide pas nrig rau hluav taws xob cua sov.
