Atmospheric pressure sintered silicon carbide haichashandiswi seabrasive, asi zvakanyanya sechinhu chitsva, uye inoshandiswa zvakanyanya muzvigadzirwa zvepamusoro-soro, senge ceramics yakagadzirwa nesilicon carbide zvinhu. Saka ndeapi mabhenefiti matanhatu emumhepo yekumanikidza sintering silicon carbide uye kushandiswa kwesilicon carbide ceramics?
Zvitanhatu zvakanakira zvemumhepo kudzvanywa sintered silicon carbide zvinhu:
1. Low density
Iyo silicon carbide zvinhu ine yakaderera density pane simbi, zvichiita kuti mudziyo ureruke.
2. Corrosion resistance
Silicon carbide zvinhu zvine yakakwira kunyungudika, kemikari inertia, thermal shock resistance, silicon carbide inoshandiswa mumabrasives, ceramic kilns, silicon carbide blanks, inogona kushandiswa muindasitiri yekunyungudutsa nekunyungudutsa ine vertical cylinder distillation vira, zvidhinha, aluminium electrolytic cell lining. , tungsten, choto chidiki uye zvimwe silicon carbide ceramic zvigadzirwa.
3, tembiricha yakakwira, kupisa kwekuwedzera coefficient kunoderedzwa
Silicon carbide zvinhu zvinogadzirwa pakupisa kwakanyanya. Mune dzimwe nzvimbo dzekushisa kwepamusoro, zvinhu zvinoda simba rekugadzirisa uye kunyatsogadzirisa zvinogona kuwanikwa nesilicon carbide ceramics inodiwa. Iyo yakanyanya tembiricha yesilicon carbide inenge 800, uye tembiricha yesimbi inongova 250. Kuverengera kwakakasharara, avhareji yekupisa kwekuwedzera coefficient yesilicon carbide muhuwandu hwe25 ~ 1400 ndeye 4.10-6 / C. Thermal yekuwedzera coefficient yesilicon carbide inoyerwa, uye mhedzisiro inoratidza kuti huwandu hwacho hudiki pane hwemamwe mabrasives uye yakakwirira tembiricha zvinhu. Sintered silicon carbide pasi pekumanikidzwa kwemhepo
4, yakakwirira yekupisa conductivity
Iyo yekupisa conductivity yesilicon carbide zvinhu yakakwira, inova chimwe chinhu chakakosha chechimiro chesilicon carbide. Iyo yekupisa conductivity yesilicon carbide yakakura kwazvo kupfuura yemamwe marefractories uye abrades, anenge 4 nguva yecorundum. Silicon carbide ine yakaderera coefficient yekuwedzera kwekupisa uye yakakwira yekupisa conductivity, saka iyo workpiece inozoiswa pasi pekushomeka kwekupisa panguva yekudziya uye kutonhora. Ichi ndicho chikonzero zvikamu zveSiC zvakanyanya kupikisa kuvhunduka.
5, high mechanical simba, kunaka kuoma
Simba remagetsi resilicon carbide zvinhu zvakanyanyisa, kudzivirira deformation yezvinhu. Silicon carbide ine yakakwira mechanical simba pane corundum.
6, kuoma kwakanyanya uye kupfeka kusagadzikana
Kuomarara kwesilicon carbide zvinhu kwakakwira zvakanyanya, uye kuomarara kweMoss gap ndeye 9.2 ~ 9.6, yechipiri chete kune diamond uye tungsten carbide. Kuenzaniswa nesimbi yesimbi zvinhu, inopa kuomarara kwakanyanya, yakaderera coefficient of friction, yakaderera kukweshana, kudiki kwepamusoro roughness uye yakanaka kupfeka kuramba pasina lubrication. Mukuwedzera, inopesana nezvinhu zvekunze, inovandudza kushivirira kwepamusoro. Sintered silicon carbide pasi pekumanikidzwa kwemhepo
Kushandiswa kweatmospheric pressure sintered silicon carbide ceramics
1, silicon carbide zvinhu kugadzirwa kweakakosha ceramics
Silicon carbide zvinhu zvinhu zvine kuoma kwakanyanya uye mutengo wakaderera, unogona kugadzira zvigadzirwa zvesilicon carbide, sesilicon carbide seals, silicon carbide sleeves, silicon carbide bulletproof plates, silicon carbide profiles, nezvimwe, izvo zvinogona kuiswa kune mechaniki zvisimbiso uye pombi dzakasiyana-siyana. Sintered silicon carbide pasi pekumanikidzwa kwemhepo
2, zirconia zvinhu kugadzirwa kweakakosha ceramics
Zirconia ceramic ine yakakwira ionic conductivity, yakanaka kugadzikana kwemakemikari uye kugadzikana kwechimiro, uye yave yakadzidzwa zvakanyanya uye inoshandiswa electrolyte zvinhu. Nekuvandudza maitiro ekugadzira zirconia yakavakirwa electrolyte firimu, kudzikisa tembiricha yekushanda uye mutengo wekugadzira wezvinhu izvi, uye kuedza kuwana maindasitiri zvakare igwara rakakosha rekutsvaga mune ramangwana.
