La cer\u00e0mica d'alumina \u00e9s un material cer\u00e0mic \u00e0mpliament utilitzat a la ind\u00fastria, i la seva producci\u00f3 \u00e9s la m\u00e9s gran entre les cer\u00e0miques d'\u00f2xid. La cer\u00e0mica d'alumina t\u00e9 moltes prestacions excel\u00b7lents: alta resist\u00e8ncia mec\u00e0nica, alta duresa, alta resist\u00e8ncia a l'a\u00efllament, resist\u00e8ncia a la corrosi\u00f3, resist\u00e8ncia al desgast i resist\u00e8ncia a altes temperatures. Pot utilitzar-se com a cer\u00e0mica electr\u00f2nica, cer\u00e0mica estructural i cer\u00e0mica qu\u00edmica i biol\u00f2gica, i s'aplica \u00e0mpliament en els sectors t\u00e8xtil, carb\u00f3, qu\u00edmic, petroli, energia i construcci\u00f3.<\/p>\n
Els m\u00e8todes de formaci\u00f3 m\u00e9s utilitzats per a la cer\u00e0mica d'alumina inclouen la premsa en sec, la fosa a calenta i la premsa isost\u00e0tica, i aquests tres m\u00e8todes tenen les seves pr\u00f2pies caracter\u00edstiques.<\/p>\n
El producte format per premsat isost\u00e0tic t\u00e9 una alta densitat, per\u00f2 la inversi\u00f3 en equipament \u00e9s elevada, la mat\u00e8ria primera es desaprofita, el temps de formaci\u00f3 \u00e9s llarg i cal un posterior mecanitzat amb torn.<\/p>\n
La premsa en sec pot formar cer\u00e0miques d'alumina de diverses mides, per\u00f2 la inversi\u00f3 en equipament \u00e9s elevada, el desgast dels motlles \u00e9s gran i no es poden formar productes amb formes complexes.<\/p>\n
L'equip de formaci\u00f3 per fosa a calenta \u00e9s senzill i rendible: requereix poc capital, el motlle es desgasta poc, \u00e9s f\u00e0cil d'operar, t\u00e9 una alta efici\u00e8ncia de producci\u00f3, genera menys residus de mat\u00e8ries primeres, proporciona una mida de producte precisa i un bon acabat, i la cer\u00e0mica d'alumina formada \u00e9s densa. La seva estabilitat de qualitat no \u00e9s bona. Abans de coure la pe\u00e7a de cera, cal retirar la cera, cosa que consumeix molta energia i t\u00e9 un llarg per\u00edode de construcci\u00f3.<\/p>\n
En la producci\u00f3 real, segons la mida espec\u00edfica de l'a\u00efllador d'alumina, seleccioneu el m\u00e8tode de formaci\u00f3 corresponent.
\nSegons els requisits de forma i densitat. L'a\u00efllant d'alumina de mides m\u00e9s grans es pot formar per premsat en sec o per premsat isost\u00e0tic. La cer\u00e0mica d'alumina de mides petites o de formes complexes es pot formar per fosa a pressi\u00f3 en calenta, que \u00e9s un m\u00e8tode de formaci\u00f3 \u00e0mpliament utilitzat en la producci\u00f3.<\/p>","protected":false},"excerpt":{"rendered":"
Alumina ceramic is a ceramic material widely used in industry, and its output is the largest among oxide ceramics. Alumina ceramic have many excellent performance, its high mechanical strength, high hardness, high insulation resistance, corrosion resistance, wear resistance, high temperature resistance, can be used as electronic ceramics, structural ceramics, chemical and biological ceramics, widely used… Read More »M\u00e8todes de formaci\u00f3 de cer\u00e0mica d'alumina<\/span><\/a><\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"neve_meta_sidebar":"","neve_meta_container":"","neve_meta_enable_content_width":"off","neve_meta_content_width":70,"neve_meta_title_alignment":"","neve_meta_author_avatar":"","neve_post_elements_order":"","neve_meta_disable_header":"","neve_meta_disable_footer":"","neve_meta_disable_title":"","footnotes":""},"categories":[8],"tags":[],"class_list":["post-25","post","type-post","status-publish","format-standard","hentry","category-technology"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/posts\/25","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/comments?post=25"}],"version-history":[{"count":3,"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/posts\/25\/revisions"}],"predecessor-version":[{"id":32,"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/posts\/25\/revisions\/32"}],"wp:attachment":[{"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/media?parent=25"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/categories?post=25"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aluminaceramic.net\/ca\/wp-json\/wp\/v2\/tags?post=25"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
