Alumina poda uye α-mhando alumina powaer
Maitiro mashanu epamusoro-kuchena alumina poda
1. Chemical resistance;
2. High-purity alumina, iyo alumina yemukati yakakura kupfuura 99%;
3. High tembiricha kuramba, zvakajairika kushandiswa pa 1600 ℃, pfupi-nguva 1800 ℃;
4. Kudzivirira kutonhora kamwe kamwe uye kupisa, kwete nyore kuputika;
5. Inotora grouting uye ine high density.
1. Kushandisa α-mhando yealuminium powder
Mune crystal lattice ye-α-mhando alumina poda, maion eokisijeni akazara mumativi ane hexagoni, uye Al3+ yakagoverwa musymmetrically muoctahedral coordination centre yakakomberedzwa neokisijeni ion.Simba relatisi rakakura kwazvo, saka nzvimbo yekunyungudika uye nzvimbo yekubikira yakakwira zvakanyanya.α-mhando oxidation Aluminium hainyungudika mumvura uye asidhi.Iyo inonzi zvakare aluminium oxide muindasitiri.Ndiyo yakakosha zvinhu zvekugadzira simbi aluminium;inoshandiswawo kugadzira zvidhinha zvakasiyana-siyana zvinoramba, zvidhinha zvinoputika, refractory tubes, uye midziyo yekuedza kupisa kwepamusoro;inogona zvakare kushandiswa seabrasives uye murazvo retardants.Agents, fillers, nezvimwewo;yakakwirira-kuchena α-mhando alumina zvakare iri mbishi kugadzirwa kweartificial corundum, artificial ruby nesafire;inoshandiswawo pakugadzirwa kwemazuva ano makuru-akabatanidzwa maseketi.
Activated alumina ine yakasarudzika adsorption kugona kwegasi, mhute yemvura uye humwe hunyoro hwemvura.Mushure mokunge adsorption yazara, inogona kumutsidzirwa nekupisa inenge 175-315 ° C kubvisa mvura.Adsorption uye kumutswa kunogona kuitwa kakawanda.Mukuwedzera pakushandiswa se desiccant, inogonawo kushambadza mhute yemafuta ekuzora kubva kune yakasvibiswa okisijeni, hydrogen, carbon dioxide, gasi rechisikigo, etc. Inogonawo kushandiswa sechinhu chinokonzera uye chinokonzera carrier uye chromatography carrier.
