Pulberea de alumin\u0103 este o component\u0103 integral\u0103 a multor produse ceramice. Este utilizat\u0103 pentru fabricarea pl\u0103cilor ceramice \u0219i a ceramicii rezistente la uzur\u0103; \u00een plus, serve\u0219te ca suport pentru catalizatori. Alumina este produs\u0103 prin amestecarea hidroxidului de aluminiu cu ap\u0103 \u0219i \u00eenc\u0103lzirea acestuia la temperaturi ridicate. Alumina calcinat\u0103 poate fi diferen\u021biat\u0103 prin dimensiunea cristalelor \u0219i con\u021binutul de sodiu. Materialele cu un con\u021binut mai sc\u0103zut de sodiu sunt potrivite pentru aplica\u021bii electronice sau substraturi ceramice.<\/p>\n
Ceramica refractar\u0103 este un material nemetalic anorganic cu o rezisten\u021b\u0103 excep\u021bional\u0103 la c\u0103ldur\u0103, ideal pentru cuptoare industriale, cazane \u0219i cuptoare. Capacitatea lor termic\u0103, conductivitatea termic\u0103 \u0219i propriet\u0103\u021bile de rezisten\u021b\u0103 la eroziune pot fi personalizate cu precizie. Acestea sunt utilizate, printre altele, \u00een cuptoare, cazane \u0219i cuptoare; capacit\u0103\u021bile lor le transform\u0103 \u00een materiale versatile \u00een numeroase contexte industriale, inclusiv \u00een cuptoare, cazane \u0219i cuptoare - oferind adesea aplica\u021bii eficiente de rezisten\u021b\u0103 la c\u0103ldur\u0103 \u00een aplica\u021bii solicitante, cum ar fi cuptoare, cazane sau cuptoare - fiind \u00een acela\u0219i timp ajustate cu precizie pentru a \u00eendeplini caracteristici specifice precum capacitatea termic\u0103, conductivitatea termic\u0103 sau rezisten\u021ba la eroziune, dac\u0103 este necesar.<\/p>\n
oferim o gam\u0103 larg\u0103 de capacit\u0103\u021bi de testare a pulberilor de alumin\u0103, de la fezabilitate la procesarea pe loturi. Inginerii pot utiliza aceste teste pentru a pune la punct formul\u0103rile pentru nevoile specifice ale aplica\u021biilor \u0219i pentru a evalua impactul asupra mediului; \u00een plus, ace\u0219tia pot determina adecvarea refractarelor pentru medii specifice \u00een func\u021bie de factori precum rezisten\u021ba la \u0219ocuri termice, compatibilitatea chimic\u0103 cu metalele topite\/ compatibilitatea cu zgurii \u0219i stabilitatea dimensional\u0103.<\/p>\n
Alumina este un suport de catalizator nepre\u021buit, datorit\u0103 iner\u021biei sale chimice \u0219i structurii sale poroase. Aceast\u0103 proprietate \u00eei permite s\u0103 contribuie la reac\u021biile chimice din industria petrochimic\u0103 \u0219i s\u0103 asigure protec\u021bia mediului. Alumina poroas\u0103 poate fi fabricat\u0103 prin sintez\u0103 hidrotermal\u0103 prin reac\u021bia hidroxidului de aluminiu cu apa \u00eentr-un vas \u00eenchis la presiuni \u0219i temperaturi ridicate, produc\u00e2nd particule ultrapure de dimensiuni nanometrice, de forme \u0219i dimensiuni specifice, care respect\u0103 anumite standarde. Aceast\u0103 reac\u021bie are ca rezultat particule de alumin\u0103 de \u00eenalt\u0103 puritate de forme \u0219i dimensiuni specifice care respect\u0103 specifica\u021bii exacte. Particulele de alumin\u0103 sinterizate pot fi apoi sinterizate \u00eempreun\u0103 pentru a forma ceramic\u0103 dens\u0103 \u0219i rezistent\u0103 cu diverse aplica\u021bii industriale.<\/p>\n
Alumina este un material remarcabil de disipare a c\u0103ldurii cu rate sc\u0103zute de dilatare termic\u0103 \u0219i o proprietate de izolator electric, ceea ce \u00eel face util \u00een aplica\u021biile electronice. pulberea de alumin\u0103 este un material eficient de disipare a c\u0103ldurii cu conductivitate termic\u0103 ridicat\u0103 (30-36 W\/m - K), coeficient sc\u0103zut de dilatare termic\u0103, stabilitate chimic\u0103 bun\u0103 \u0219i performan\u021b\u0103 de izolare electric\u0103. Este utilizat pe scar\u0103 larg\u0103 \u00een dispozitive electronice, vehicule cu energie nou\u0103, comunica\u021bii 5G \u0219i alte domenii.<\/p>\n
Pulberea de alumin\u0103 este de obicei de culoare alb\u0103 sau alb-deschis \u0219i prezint\u0103 o structur\u0103 cristalin\u0103. De asemenea, poate fi presat\u0103 uscat, presat\u0103 izostatic, presat\u0103 la cald, extrudat\u0103, turnat\u0103 \u00een band\u0103, turnat\u0103 prin injec\u021bie \u0219i amestecat\u0103 cu diver\u0219i lubrifian\u021bi organici sau anorganici, plastifian\u021bi sau electroli\u021bi pentru utilizare.<\/p>","protected":false},"excerpt":{"rendered":"
