Calcined Alumina Micro-Powder Optimize Siab-Ceramics thiab Refractories li cas?

Xaiv siab -puritycalcined aluminamicro powder can improve the structural density, mechanical strength, and thermal conductivity of wear-resistant ceramics and refractory material formulations. Calcined alumina yog ua tiav los ntawm cov khoom siv sodium tsawg los ntawm micro sib tsoo thiab kev ua kom zoo dua qub, muab cov qauv alpha ruaj khov uas tuaj yeem tiv thaiv thermal poob siab thiab microcracks. Los ntawm kev koom tes nrogHUAO, cov neeg siv khoom lag luam tuaj yeem tau txais kev lees paub nruj calcined alumina micro hmoov, uas tau ua tib zoo tsim los txhim kho cov khoom zoo thiab cov khoom siv lifespan nyob rau hauv huab cua kub thiab txhua yam ib puag ncig.

 

 

 

Calcination ntawm alumina nplua hmoov yog ua tiav los ntawm siab -kub calcination los hloov cov txhuas hydroxide raw rau hauv crystalline alpha alumina ( -Al₂O₃) Qhov kev hloov pauv no ua rau cov pob zeb muaj zog heev nrog cov thermal thiab hluav taws xob zoo:

Alpha alumina tuaj yeem tswj tau siv lead ua kev ncaj ncees thiab ntim ruaj khov ntawm qhov kub thiab txias, tiv thaiv cov qauv deformation ntawm kiln rooj tog thiab hauv ob sab phlu. Nws muaj siab Mohs hardness, muaj zog load- bearing muaj peev xwm thiab siab hnav tsis kam nyob rau hauv loj zawv zawg los yog sib tsoo. Calcined alumina combines high dielectric rwb thaiv tsev nrog zoo cua sov dissipation, ua rau nws haum rau hluav taws xob substrates thiab thermal tswj systems.

 

 

 

 

Sib piv cov tshuaj muaj pes tsawg leeg, alpha-theem hloov dua siab tshiab, thiab particle loj tis rau cov txheej txheem tsim tshwj xeeb ua kom pom kev zoo sintering ntom thiab tus cwj pwm rheological.HUAOmuab ob qho tseem ceebcalcined aluminamicro- cov hmoov qib tailored rau industrial ceramics, refractories, thiab deg tiav daim ntaub ntawv:

Vim nws cov thermal, tshuaj, thiab lub cev tsis zoo, calcined alumina hmoov zoo yog ib qho tseem ceeb raw khoom rau ntau yam kev lag luam hnyav:

• Cov khoom siv refractory: tuaj yeem siv rau cov cement castables tsawg, zawv zawg rooj vag, thiab cov khoom siv amorphous refractory.
• Structural ceramics: applied to high-density wear-resistant linings, sealing rings, and ceramic valve components.
• Cov khoom siv hluav taws xob: siv los ua insulating substrates thiab cov khoom siv hluav taws xob.
• Architectural ceramics: ntxiv rau lub tsheb lub cev qauv thiab cov txheej txheem glazes.
• Hnav cov ntaub ntawv tiv thaiv thiab kev tshaj tawm: ua lub ntsiab matrix rau ceramic sib tsoo hlaws, hnav- cov cib tiv taus, thiab cov kav dej hauv ob sab phlu
• Polishing thiab precision sib tsoo: Uniform particle hardness tso cai rau siab -precision nto tiav thiab zoo polishing ntawm hlau, optical iav, thiab semiconductor chips.

 

 

 

Xyuas kom cov tshuaj purity thiab sib xws ntawm particle loj tis ntawm txhua batch ntawm cov khoom yog ib qho tseem ceeb kom tsis txhob tawg thaum lub sij hawm ceramic firing los yog refractory cov txheej txheem kho. Raws li cov chaw tsim khoom thiab cov chaw muag khoom ntawm alumina ceramics thiab cov ntaub ntawv raw khoom, peb nruj me ntsis saib xyuas qhov zoo ntawm txhua qhov kev txiav txim.

HUAOua haujlwm raws li kev tswj hwm tau ntawv pov thawj thiab tuav ISO9001, ISO14001, thiab ISO45001 ntawv pov thawj.
