Silicon Nitride Hmoov Si3N4

Vim tias Silicon nitride ceramic nrog cov khoom zoo li no, tib neeg feem ntau siv nws los tsim cov khoom siv kho tshuab xws li bearings, roj turbine blades, mechanical seal rings, thiab pwm mus tas li. Yog tias silicon nitride ceramics uas tiv taus qhov kub thiab tsis yooj yim rau kev hloov cov cua sov yog siv los tsim cov cua sov saum npoo ntawm lub cav, nws tsis tuaj yeem txhim kho qhov zoo ntawm lub cav diesel, txuag roj, tab sis kuj txhim kho thermal efficiency.

Kev taw qhia thiab cov yam ntxwv ntawm silicon nitride hmoov

Silicon nitride yog cov khoom siv ceramic nrog siab hardness, ruaj khov qauv, me me coefficient ntawm thermal expansion, zoo heev oxidation thiab yaig kuj, thiab zoo heev thermal thiab tshuaj zog. Silicon nitride ceramic hmoov muaj purity siab, siab nitrogen cov ntsiab lus, nqaim particle loj tis, siab sintering kev ua si, ruaj khov tshuaj muaj pes tsawg leeg, decomposition kuj, kub oxidation kuj, tshwj xeeb tshaj yog kub lub zog, siab hardness, zoo hnav tsis kam, zoo tshav kub thiab zog. cuam tshuam tsis kam, thiab nws tus kheej-lubricating nyhuv, uas tsim ib tug zoo diffuse theem nyob rau hauv cov khoom sib xyaw, yog li txhim kho kev ua tau zoo ntawm cov khoom sib xyaw.

High mechanical zog, hardness ze rau corundum, nws tus kheej-lubricating, hnav-resistant. Lub zog flexural ntawm chav tsev kub tuaj yeem siab li 980MPa lossis ntau dua, uas tuaj yeem muab piv nrog cov hlau alloy, thiab lub zog tuaj yeem khaws cia kom txog rau thaum 1200 degree tsis txo qis.

Zoo thermal stability, me me coefficient ntawm thermal expansion, thermal conductivity, zoo thermal shock kuj, los ntawm chav tsev kub txog 1000 degree thermal shock yuav tsis tawg.

Cov khoom siv tshuaj muaj zog ruaj khov, yuav luag tag nrho cov inorganic acids (tshwj tsis yog HF) thiab caustic soda (NaOH) cov kev daws teeb meem nrog cov concentration tsawg dua 30% kuj tuaj yeem tiv thaiv kev yaig ntawm ntau cov organic tshuaj, thiab nws tsis ntub ntau yam tsis-ferrous. hlau melts (tshwj xeeb tshaj yog molten aluminium), thiab muaj peev xwm tiv taus hluav taws xob muaj zog irradiation.

Qhov ceev yog tsawg, qhov tshwj xeeb lub ntiajteb txawj nqus me me, tsuas yog 2/5 ntawm cov hlau, thiab cov hluav taws xob rwb thaiv tsev yog qhov zoo.

Cov yam ntxwv ntawm silicon nitride

Cov khoom muaj purity siab, me me particle loj, uniform tis, loj tshwj xeeb deg cheeb tsam, siab deg kev ua si thiab tsawg bulk ntom; Lub ultraviolet reflectivity yog ntau tshaj 95% thiab qhov nqus ntawm infrared band yog ntau tshaj 97%, nrog cov tshuaj zoo corrosion kuj, muaj zog lubrication, siab hardness thiab me me zawv zawg txhuam coefficient.
