Qee qhov kev sib piv ntawm zirconia ceramic pob thiab silicon nitride pob
Ob lub zirconia ceramic npas thiab silicon nitride ceramic pob yog cov khoom siv ceramic, thiab tuaj yeem siv los ua cov khoom sib tsoo. Nrog siab precision, lawv kuj tuaj yeem siv los ua cov pob valve thiab cov kabmob. Lawv siv zoo ib yam.
Yog tias muab piv los ntawm cov muaj pes tsawg leeg thiab cov yam ntxwv, tseem muaj qhov sib txawv loj.
1. Kev sib piv ntawm lub cev muaj zog.
Nyob rau hauv cov nqe lus ntawm lub cev khoom ntawm zirconia ceramic pob, lawv zoo heev nyob rau hauv hnav tsis kam thiab corrosion kuj, thaum silicon nitride ceramic npas kuj muaj zoo tib yam kev ua tau zoo. Nyob rau tib lub sijhawm, silicon nitride ceramic pob kuj ua tau zoo hauv kev ua haujlwm raug. Yog li ntawd, nyob rau hauv daim ntawv thov kev lag luam ntawm high-precision machinery kev lag luam, xws li super-precision bearings, ntxiv rau kev siv dav hlau pob, ceramic pob kuj tau pib nrov hauv precision bearings. Piv nrog rau cov kabmob steel pob, cov pob zeb ceramic muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab tiv thaiv xeb, thiab kev ua haujlwm raug zoo dua li cov pob steel. Nyob rau tib lub sijhawm, nws tuaj yeem tiv taus qhov kub thiab txias hauv ib puag ncig kub. Yog li ntawd, cov khoom siv ceramic tau tshwm sim hauv cov kabmob thiab lwm yam khoom siv ultra-precision, xws li cov lus qhia, cov khoom siv zawv zawg kab, thiab lwm yam, thiab muaj kev nyiam los hloov cov pob steel.
2. Xim.
Ntau tshaj 80 feem pua ntawm zirconia ceramic pob yog cov xim dawb, thiab cov pob zeb zirconia dawb yog lawv cov xim ntuj. Tab sis qee zaum nws pom tias lub pob ceramic yog daj ntseg lossis grey, vim tias cov khoom siv zirconia muaj me me ntawm impurities. Zirconia ceramic npas muaj qhov zoo ntawm kev ua haujlwm siab, siab flexural zog thiab siab hnav tsis kam, zoo thermal rwb thaiv tsev kev ua tau zoo, thiab thermal expansion coefficient ze ntawm cov pob steel.
Silicon nitride ceramic pob yog tsuas yog ua los ntawm carbon dub. Nws tiv taus qhov kub thiab txias, thiab nws lub zog tuaj yeem tswj tau ntawm qhov kub ntawm 1200 ° C yam tsis poob. Tom qab rhuab, nws yuav tsis yaj mus rau hauv ib tug yaj. Nws yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws hauv ntiaj teb.
Cov teb uas siv tau:
Semiconductor, LCD tsim cov cuab yeej, cov khoom siv electroplating, cov khoom siv hluavtaws fiber ntau, cov khoom siv kho qhov muag, ntau yam kev kho cua sov, cov khoom siv nqus tsev, thiab lwm yam .; kuj tseem siv tau rau hauv cov kabmob sib xyaw, cov cuab yeej ua haujlwm txias, ntau lub log qhia, ntau yam li qub, cov khoom siv nqus tsev thiab hauv ntau qhov chaw hnyav.
