Porous ceramic is an inorganic non-metallic powder sintered body ine humwe huwandu hwevoids.Musiyano wakakosha kubva kune dzimwe inorganic non-metallic (dense ceramics) ndewekuti ine voids (pores) uye ndeapi vhoriyamu muzana yevoids (pores) iyo ine.Zvinoenderana nemaitiro ekugadzira pore uye voids, zviumbwa zvine porous zvinogona kupatsanurwa kuita: zviumbwa zvine furo, zviumbwa zvehuchi, uye granular ceramics.
Nekuda kwekuvapo kwehumwe huwandu hwepores, chimiro, zvivakwa uye mabasa eporous ceramics zvakashandurwa zvakanyanya.Kana ichienzaniswa nedense ceramics, porous ceramics ine zvinotevera zvishanu maitiro:
1. Diki yakawanda yakawanda uye uremu huremu.
2. Yakakura chaiyo nzvimbo uye yakanaka kusefa basa.
3. Low thermal conductivity, yakanaka thermal uye sound insulation properties.
4. Yakanaka kemikari uye kugadzikana kwemuviri, inogona kuenderana neyakasiyana-siyana inoodza nzvimbo, ine yakanaka mechanical simba uye kuoma, uye kunaka kupisa kudzivirira.
5. Nzira yacho iri nyore uye mari yakaderera.
1. Inoshandiswa kune kusefa uye kupatsanura zvishandiso
Chishandiso chesefa chinoumbwa neplate-shaped kana tubular zvigadzirwa zve porous ceramics ine hunhu hwenzvimbo yakakura yekusefa uye yakanyanya kusefa kunyatsoita.Inoshandiswa zvakanyanya mukucheneswa kwemvura, kupatsanurwa uye kusefa kwemafuta, uye kupatsanurwa kwezvinogadziriswa organic, acid-base mhinduro, zvimwe zvinwiwa viscous uye mweya wakatsikirirwa, coke oven gasi, steam, methane, acetylene uye mamwe magasi.Nekuti porous ceramics ine zvakanakira kukwirisa tembiricha kuramba, kusapfeka, kusakara kwekemikari, uye kusimba kwemuchanicha, vari kuramba vachiratidza mabhenefiti avo akasiyana munzvimbo dzekushandisa dzemvura inoparadza, tembiricha yepamusoro, uye simbi dzakanyungudutswa.
2. Inoshandiswa kune inopfekwa neruzha uye kuderedza ruzha
Sechinhu chinotora ruzha, porous ceramics inonyanya kushandisa basa rayo rekuparadzira, ndiko kuti, kuparadzira mweya wemhepo unokonzerwa nemasaisai eruzha kuburikidza nechimiro cheporous kuzadzisa chinangwa chekunzwa inzwi.Porous ceramics sezvinhu zvinotora ruzha zvinoda diki pore saizi (20-150 μm), yakakwirira porosity (pamusoro pe60%) uye yakakwirira mechanical simba.Porous ceramics ikozvino yave kushandiswa mukukwirira-kukwira zvivakwa, tunnels, subways nedzimwe nzvimbo dzine zvakanyanyisa kuchengetedzwa kwemoto zvinodiwa, pamwe nenzvimbo dzine yakakwirira ruzha rwekudzivirira zvinodiwa senge TV yekutapurirana nzvimbo nemabhaisikopo.
3. Inoshandiswa kune maindasitiri catalyst mutakuri
Sezvo porous ceramics ine yakanaka adsorption kugona uye chiitiko, mushure mekufukidzwa necatalyst, iyo shanduko inoshanda uye chiyero chekuita inovandudzwa zvakanyanya mushure mekunge reaction fluid inopfuura nepamapores e porous ceramics.Parizvino, iyo yekutsvagisa inotariswa ye porous ceramics se catalyst inotsigira ndeye inorganic separation catalytic membrane, iyo inosanganisa kupatsanurwa uye catalytic zvimiro zve porous ceramic zvinhu, uye nekudaro ine huwandu hwakasiyana hwekushandisa tarisiro.
4. Inoshandiswa kune zvakakosha zvemagetsi zvikamu
Nheyo yekushanda yehumidity sensor uye gasi sensor element yeceramic sensor ndeyokuti kana iyo microporous ceramic yakaiswa mugasi kana mvura yepakati, zvimwe zvikamu zviri mukati zvinoshambadzirwa kana kubatwa nemuviri weporous, uye zvinogona kana ikozvino. iyo microporous ceramic iri panguva ino.shanduko yekuona kuumbwa kwegasi kana mvura.Ceramic sensors ine hunhu hwekupisa tembiricha kuramba, corrosion kuramba, nyore kugadzira maitiro, inonzwisisika uye yakaringana kuyedzwa, nezvimwewo, uye inogona kuve yakakodzera kune dzakawanda dzakakosha zviitiko.
