Calcined Alumina Ultrafine For High-Performance Refractories

Calcined alumina poda inogadzirwa nekuverengera kwakananga kweindasitiri alumina kana aluminium hydroxide pakudziya kwakakodzera kuti ishanduke kuita yakagadzikana crystallineα-alumina, yobva yakuya kuita diki-hupfu. Calcined micro- powders inogona kushandiswa mumasiraidhi gedhi, nozzles, uye alumina zvidhinha. Uye zvakare, anogona kushandiswa mucastables ane silica fume uye reactive alumina poda, kuderedza kuwedzera kwemvura, porosity uye kuwedzera simba, vhoriyamu kugadzikana.

Zvigadzirwa zveAlumina zvine calcined alumina poda seyakagadzirwa zvine simba remuchina, kuomarara kwepamusoro, kukwirira kwemagetsi resistivity uye yakanaka yekupisa conductivity. Iyo calcined alumina micropowder inogona kushandiswa zvakanyanya mumidziyo yemagetsi, zvimiro zveceramic, refractories, abrasives, polishing zvinhu, et.

Calcined aluminas ndeye alpha-aluminas ayo anonyanya kusanganisira sintered agglomerates ega ega alumina makristasi. Saizi yeaya makristasi ekutanga zvinoenderana nechiyero checalcination uye saizi yeagglomerate pamatanho anotevera ekukuya. Ruzhinji rwe calcined aluminas inopiwa pasi (<63μm) kana yakanaka-pasi (<45μm). Iwo ma agglomerate haana kukoromoka zvakazara panguva yekukuya, inova musiyano wakakosha kubva kune reactive aluminas akanyatso kudzika nebatch kugaya maitiro. Calcined aluminas inoiswa pasoda yemukati, particle size uye degree recalcination. Ground uye yakatsetseka-ivhu calcined aluminas anoshandiswa senge matrix filler kukwidziridza mashandiro echigadzirwa chezviumbwa zvakanyanya zvichibva pane zvakasikwa mbishi zvinhu.

Calcined aluminas ane chidimbu saizi yakafanana neyepasi mineral aggregates uye saka anogona nyore kutsiva aggregates nekuchena kwakaderera. Nekuwedzera iyo yakazara alumina yemukati yemusanganiswa uye nekuvandudza yavo particle kurongedza kuburikidza nekuwedzera kwealumina yakanaka, iyo refractoriness uye michina zvivakwa, senge inopisa modulus yekuputika uye abrasion kuramba, inovandudzwa. Iko kudiwa kwemvura kwe calcined aluminas kunotsanangurwa nehuwandu hweasara agglomerates uye nzvimbo yepamusoro. Naizvozvo, calcined aluminas ine yakaderera nzvimbo nzvimbo inosarudzwa semazadza muzvidhinha uye zvinokandwa. Special calcined aluminas ine nzvimbo yepamusoro yepamusoro, inogona kubudirira kutsiva ivhu seplasticizer mupfuti uye ramming musanganiswa.

Calcined Aluminas yeRefractories

Nekuda kweakanakisa tembiricha yea-Alumina, Calcined Aluminas anoshandiswa mune akawanda refractory maapplication, ese mune monolithic uye akaumbwa zvigadzirwa.

Product Performance
Zvichienderana nedhigirii rekugaya uye saizi yekristaro, Calcined Aluminas inoshanda akasiyana emabasa akasiyana mune refractory formulations.

Zvinonyanya kukosha ndezvi:
• Natsiridza mashandiro echigadzirwa nekuwedzera huwandu hweAlumina hwese hwemagadzirirwo aya uchishandisa zvechisikigo mbishi kuitira kuti uvandudze refractoriness uye ma mechanical properties.
• Kuvandudza particle packing nekuwedzera kuwanda kwezvimedu zvakanaka zvichiita kuti zvive nani simba remagetsi uye abrasion resistance.
• Gadzira matrix epamusoro-refractoriness uye yakanaka yekupisa kuvhunduka kusamira nekuita nezvinosungirirwa seCalcium Aluminate Cement uye/kana ivhu.
