Lub Hnav Alumina Hollow Pob Cib Cib yog cov cua sov-insulating ua cov khoom lag luam alumina ua cov khoom siv raw.

Kev Ua Neej Zoo Nrov Hnav Alumina Hollow Bricks muaj ntau dua li ntawm 1.3%, ib qho txiaj ntsig zoo tshaj plaws ntawm 1.3%, ib qho txiaj ntsig Fe ...}}}}}%, muaj compressive Lub zog tsis pub tsawg tshaj 9.8MPA, muag muag muag ({{} Kev npaj ntawm Alumina Hollow cov pob khoom siv muaj alumina ua cov khoom siv raw, uas tau melted los ntawm hluav taws xob melting thiab tom qab ntawd txau.

Lub tshuab hluav taws xob melting yog ib qho cub hluav taws xob. Lub pas dej Molten yog ua los ntawm graphite cov khoom lossis lwm yam khoom hluav taws-resistant, thiab cov hluav taws xob yog cov khoom lag luam graphite yog cov khoom lag luam graphite yog cov khoom lag luam graphite. Tom qab ntxiv cov khoom siv roj alumina hmoov rau hauv cov pas dej molten, nws tuaj yeem siv tau rau melting. Thaum qhov ntsuas kub ntawm molten ua kua nce mus lossis tshaj li 22 {{{{{5} {{5} {{5} {{5} {{5} { Nyob rau tib lub sijhawm, cov dej ua kua molten yog txau nrog huab cua compressed. Vim yog viscosity thiab nto nro ntawm molten kua, molten kua hollow pob qhwv hauv huab cua thaum lub sij hawm txau thiab txheej txheem hws. Tom qab tau sau thiab tshuaj ntsuam, lawv tau khaws cia cais raws li cov sib txawv rau kev siv standby. Tus lej piv ntawm hollow alumina npas ntawm qhov sib txawv ntawm qhov sib txawv sib txawv nrog cov huab cua sib haum sib xyaw ua ke. Qhov ntau dua lub siab, qhov ntau cov pob me muaj. Lub phab ntsa tuab ntawm lub hollow pob sib txawv nrog cov particle loj. Thaum lub particle loj hloov nyob rau hauv thaj tsam ntawm 5 ~ 0. 5mm, phab ntsa thickness hloov nyob rau hauv thaj tsam ntawm 0.3mm raws li.

Cov khoom lag luam

Qhov loj dua lub particle loj ntawm lub pob hollow, tus me dua nws cov ntuj ntom ntom; Qhov me me qhov loj me me, muaj ntau dua nws cov ntuj ntom ntom. Piv txwv li: thaum lub particle loj yog 5.13 ~ 3.22 hli, lub ntom ntom nti yog 47 {{8} g / l; Thaum nws yog 3.22 ~ 2. {0 hli, nws yog 67 {13 {13} g / l; Thaum nws yog 2. {{0 ~ 1. {17}} hli, nws yog 810g / l; Thaum nws yog 1.0 ~ 0.5 hli, nws yog 915 g / l.

Kev tsim khoom ntawm lub hnab sib tw Alumina Hollow pob Cib Cib

Alumina hmoov zoo yog tsim los ntawm cov khoom siv alumina ua cov khoom siv raw, calched ntawm 1500 degree, pickled thiab qhuav.

Cov phau ntawv siv rau lub teeb Alumina Hollow pob Cib Cib yog ib qho aqueous daws los yog kev daws teeb meem ntawm txhuas dihydrogen phosphate.

Lub particle loj ntawm hollow alumina npas feem ntau 5-0. 5 hli, thiab cov tshuaj ntsuab ntawm cov hmoov zoo alumina yog 30% {}}}%; Qhov ntau npaum li cas ntawm phau ntawv.

Sib tov cov lus saum toj saud ensly, thiab ua rau lawv los ntawm kev co moulding. Tom qab ziab, cov cib raug rho tawm ntawm 1500-1800 degree kom tau txais cov cib; Lawv kuj tseem tuaj yeem tsim ua cov khoom tsis tuaj yeem uas tsis muaj kev tua hluav taws, lossis ncaj qha tsim cov rauv rauv ntaub nrog amorphoud cov ntaub ntawv. Lub teeb yuag hollow alumina pob cib feem ntau yog siv los ua kab ntawv rau cov khoom siv kub siab rau cov khoom siv refractory, electronics, thiab ceramic Industries; Thermal rwb thaiv tsev cov khaubncaws sab nraud povtseg rau cov khoom siv hluav taws xob kub, thiab cov pa hluav taws xob ua hluav taws xob rau kev lag luam petrochemical. Daim ntawv thov nyob rau hauv cov teb saum toj no tuaj yeem txuag lub zog los ntawm 20% -30%. Lub Hnav Alumina Hollow Pob Cib Cib Siv Raws Li Cov Linings Rau Kev Kub Kub Kilns. Cov cua sov ua rau lub sijhawm ci tsis tuaj yeem nrawm, lwm yam kev tawg yuav tshwm sim, txo lub zog thiab kev pabcuam lub neej. Vim yog lawv cov paj hlwb zoo nkauj, lawv tsis tuaj yeem siv rau hauv thaj chaw uas tau sib cuag nrog swb, tsis yog lawv yuav raug puas tsuaj los ntawm kev swb.
