Daim ntawv thov tseem ceeb ntawm cov tshuaj tiv thaiv-sintered silicon carbide thiab cov yam ntxwv ntawm cov nplhaib sealing

Silicon nitride (SiC) yog cov xuab zeb quartz, calcined petroleum coke (lossis thee coking), ntoo slag (tshuaj ntsuab silicon nitride yuav tsum ntxiv ntsev) thiab lwm yam khoom siv raw, los ntawm lub cub tawg hluav taws xob kub tas mus li. Silicon nitride sealing ring yog cov khoom silicon nitride ua los ntawm cov khoom siv silicon carbide. Yog li cov ntawv thov tseem ceeb ntawm cov tshuaj tiv thaiv-sintered silicon carbide thiab cov yam ntxwv ntawm cov foob yog dab tsi?

Daim ntawv thov tseem ceeb ntawm kev sib xyaw ua ke ntawm silicon carbide:

1. Kev siv rau kev lag luam hlau yog siv silicon nitride uas tiv taus cua sov, muaj zog heev, ua kom muaj cua sov zoo, tiv taus kev cuam tshuam, thiab siv cov khoom siv raw uas kub thiab txias tas mus li, xws li lub tank fractionation furnace. Lub tais rectifier furnace, lub cell electrolytic txhuas, lub hauv paus tooj liab melting furnace, lub raj zinc hmoov furnace arc, lub raj thermocouple tiv thaiv, thiab lwm yam.

2. Kev siv rau kev lag luam hlau siv cov silicon nitride etching. Tiv taus kub thiab tiv taus kev sib txhuam. Vim nws cov thermal conductivity zoo, nws yog siv rau kev sib txuas ntawm cov qhov cub loj thiab nruab nrab kom txhim kho lub neej ua haujlwm.

3. Kev lag luam hlau siv silicon nitride concentrator, lub zog tsuas yog thib ob tom qab kub hlau, muaj zog hnav tsis kam, nws yog qhov zoo tagnrho rau kev hnav tsis kam, cov kav dej, centrifugal impeller, twj tso kua mis, rotary machinery, mining lining, thiab lwm yam. Nws yog cov khoom siv raw zoo, thiab nws kuj zoo hnav tsis kam. Lub neej ua haujlwm ntawm yas yog 5 txog 20 npaug, thiab nws yog ib qho ntawm cov khoom siv raw zoo tshaj plaws rau kev ua si nawv dav hlau.

4. Daim ntawv thov ntawm cov coefficient hloov pauv cua sov hauv qib kev tsim khoom lag luam ntawm cov khoom siv kho kom zoo nkauj hauv tsev porcelain thiab cov xuab zeb log. Cov yam ntxwv ntawm lub zog cua sov thiab lub zog kub siab, kev tsim khoom thiab kev tsim khoom ntawm cov ntawv hlau kiln tsis tsuas yog txo qhov ntim ntawm lub kiln, tab sis kuj txhim kho qhov ntim cia thiab cov khoom zoo ntawm lub kiln, thiab txo lub sijhawm tsim khoom, uas yog cov khoom siv tsis ncaj qha rau kev hlawv cov xim ceramic.

5. Kev siv kev tiv thaiv ib puag ncig thiab qib txuag hluav taws xob muaj kev ua tau zoo ntawm cov cua sov thiab tiv taus cua sov, thiab lub tshuab hloov pauv cua sov txuag tau 20%, kev siv roj 20%, kev siv roj 35%, thiab kev ua haujlwm ntau ntxiv 20-30%. Tshwj xeeb, qhov kev tiv thaiv hnav ntawm cov yeeb nkab tso dej tawm siv hauv cov chaw ua haujlwm tsuas yog 6 txog 7 npaug ntawm cov khoom siv hlau sib xyaw.

Cov yam ntxwv ntawm cov roj hmab silicon carbide reaction sintered:

1, kub tsis kam

Vim yog cov yam ntxwv ntawm cov ntaub ntawv silicon nitride, cov foob pob silicon nitride muaj kev tiv taus kub siab, thiab cov txheej txheem sib txawv muaj ntau hom kev tiv taus kub. Cov foob pob silicon nitride uas ua rau muaj kev cuam tshuam tuaj yeem siv tau los ntawm 1300 degrees, thiab cov foob pob silicon nitride uas tsis muaj kev nyem siab tuaj yeem ncav cuag 1600 degrees.

2. Kev tiv thaiv xeb

Lub nplhaib sib khi silicon nitride tuaj yeem siv los ntawm cov kua qaub thiab alkali muaj zog, thiab cov nyhuv sib khi tsis yooj yim txo.

3, hnav tsis kam

Cov nplhaib foob silicon carbide uas tau ua los ntawm cov tshuaj tiv thaiv sintered raws li cov txheej txheem carding, yog li ntawd daim phiaj xwm yog qhov tseeb thiab du, ua ke nrog kev hnav tsis kam ntawm cov ntaub ntawv silicon carbide, cov nplhaib foob silicon nitride tuaj yeem siv los txhuam ib leeg. Cov yam ntxwv kub siab tas mus li tsis yooj yim txo cov yam ntxwv puas tsuaj.

4. Kev yoog tau

Cov khoom siv raw sintered silicon carbide reactivity tsuav yog muaj qee yam kev siv tshuab ua, nws tuaj yeem hloov pauv mus rau ntau yam qauv ntawm cov ntaub plaub embryo, kev ua tiav theem ob, kom cov neeg siv khoom xav tau cov khoom.
