Silicon Nitride Ceramics

 

Silicon nitride tsis hnov ​​​​mob nrog nitric, sulfuric thiab hydrochloric acids, tsis muaj zog reacts nrog orthophosphoric acid thiab intensive nrog hydrofluoric acid. Nws yog decomposed los ntawm melts alkalis, oxides thiab carbonates ntawm alkali hlau. Nws tsis hnov ​​​​mob nrog chlorine txog 900 degree, nrog hydrogen sulfide mus txog 1000 degree, nrog hydrogen txog 1200 degree. Nws tsis hnov ​​​​mob nrog melts ntawm Al, Pb, Sn, Zn, Bi, Cd, Cu; Nws tsim silicides nrog kev hloov pauv hlau, thiab silicates nrog hlau oxides siab tshaj 1200 degree. Oxidation ntawm silicon nitride hauv huab cua pib tshaj 900 degree.

Kev lag luam tshuaj

Cov khoom siv silicone nitride ceramic yog siv los hnav-tiv taus thiab corrosion- cov khoom tiv taus, xws li pob li qub, lub cev twj tso kua mis, lub tshuab hluav taws xob, cov lim dej, thiab lwm yam.

Cov ntaub ntawv Silicon nitride kuj tau siv dav hauv kev lag luam hluav taws xob, tub rog thiab nuclear.

 

 

 

 

 

 

 

 

 

 

Q: Koj them tus nqi coj mus kuaj li cas?
A: Yog tias koj xav tau cov qauv ntawm peb cov Tshuag, peb tuaj yeem muab rau koj dawb, tab sis tus nqi dawb yuav tsum nyob ntawm koj sab. Yog tias koj xav tau qhov tshwj xeeb loj, Peb yuav tsub tus nqi ua piv txwv uas yuav tau them rov qab thaum koj tso qhov kev txiav txim.
Q: Koj lub sijhawm khoom xa tuaj yog dab tsi?
A: Yog tias peb muaj Tshuag, tuaj yeem xa hauv 1-7 hnub; yog tias tsis muaj Tshuag, xav tau 5-30 hnub, nyob ntawm seb muaj pes tsawg.

 

Q: Koj qhov zoo yog dab tsi?

A: Peb muaj peb tus kheej lub Hoobkas, cov neeg ua haujlwm zoo nkauj thiab cov kws tshaj lij kev tsim khoom thiab kev ua haujlwm thiab pab pawg muag khoom. Zoo tuaj yeem lav. Peb muaj kev nplua nuj nyob hauv metallurgical steelmaking teb.

Q: Puas yog tus nqi sib tham?

A: Yog, thov hu rau peb txhua lub sijhawm yog tias koj muaj lus nug. Thiab rau cov neeg siv khoom uas xav kom ua lag luam loj, peb yuav ua qhov zoo tshaj plaws los txhawb.
