Product Detail

Khoom cim npe

Ceramic caj npab tsim los ntawm peb lub tuam txhab yog ua los ntawm high purity ceramic raw cov ntaub ntawv, uas yog tsim los ntawm txias isostatic nias, kub sintering thiab precision machining. Qhov tseeb qhov ntev tuaj yeem ncav cuag ± 0.001mm, qhov kawg tuaj yeem ncav cuag Ra0.1, thiab kev siv kub tuaj yeem ncav cuag 1600 ℃. Peb lub tuam txhab txais cov cuab yeej tshwj xeeb ceramic bonding tshuab, kev siv kub ntawm lub hollow ceramic caj npab tom qab kev sib raug zoo tuaj yeem ncav cuag 800 ℃.

Alumina ceramics yog cov khoom siv tshwj xeeb ceramics, hauv cov khoom siv ceramic yog tshwj xeeb ceramics, belongs rau oxide ceramics, nws Rockwell hardness yog HRA80-90, hardness yog thib ob rau pob zeb diamond, deb tshaj qhov hnav tsis kam hnav-resistant steel thiab stainless. steel, nws qhov ceev yog 3.5g / cm3, sib dua li hlau, lub teeb yuag, hnav tsis kam, kub tsis kam, txhua yam ntawm cov yam ntxwv zoo heev concentrated ua ke, Alumina ceramics yog nrov thiab ua tus tshaj plaws. dav siv cov ntaub ntawv ceramic hauv oxide ceramics.

Los ntawm cov txheej txheem kub-kub sintering, alumina tsim cov qauv nruj, cov qauv siv lead ua. Cov qauv no muab nws siab hardness, siab melting point thiab zoo heev tshuaj stability. Cov khoom siv nyob rau hauv daim teb ntawm electronics yuav tsum muaj qhov ua kom zoo, yog li kom ntseeg tau tias zoo folding thiab coj kev tiv thaiv zoo.

Hauv kev tsim micro thiab nano, qhov ntom ntawm cov khoom ncaj qha cuam tshuam rau nws txoj kev khoov thiab hnav tsis kam. Nyob rau hauv cov ntaub ntawv ntawm tus neeg hlau caj npab, nws ntom sintered qauv muab nws zoo heev flexural zog thiab siab hardness. Qhov microstructure no ua rau cov neeg kho tshuab txhais caj npab kom ruaj khov cov khoom siv kho tshuab hauv ntau qhov chaw ua haujlwm nyuaj, kom ntseeg tau tias nws muaj peev xwm thauj khoom zoo heev thiab txuas ntxiv nws lub neej kev pab cuam. Ib qho ntxiv, cov khoom lag luam uas muaj cov qauv caj npab, kuj tseem muaj peev xwm txo cov khoom siv tsis kam, uas tuaj yeem ua kom muaj zog ua haujlwm thaum siv thiab tswj kev nyiam huv ntawm cov chaw tsim khoom.
