Calcium Aluminate Cement
MOQ<5TONS
Khoom Description
High-purity calcium aluminate cement minimizes impurities xws li silica thiab hlau oxide thiab muaj kev ruaj ntseg siab. Nws yog tsuas yog siv rau cov tsoos castables ua haujlwm ntawm 1800 degree. Nws muaj zog durability, zoo hluav taws kub tsis kam thiab kev tsim kho kev ua tau zoo, thiab zoo heev kub burst kuj.
Nws tuaj yeem muab faib ua ob hom raws li nws cov tshuaj muaj pes tsawg leeg: zoo tib yam calcium-aluminate cement (Al2O3 53} ~ 72%, CaO 21 ~ 35%) thiab ntshiab calcium aluminate castable cement (Al2O3 72 ~ 82 , CaO 19 ~ 23%). Ordinary calcium aluminate cement tuaj yeem muab faib ua ob hom: hom hlau tsawg (Fe2O3<2%) and high iron type (Fe2O37~16%). Low iron calcium-aluminate cements can be divided into alumina cement (Al2O353~56 %, CaO 33～35%), aluminum-60 cement (Al2O3 59%～61%, CaO 27～31%) and low aluminate cement (Al2O3 65～70%, CaO 21～24%). Pure calcium-aluminate cement can be divided into two types: ordinary type (Al2O3 72~78%) and ultra-high aluminum type (Al2O3 78~85%). In addition, there is quick-hardening and early-strength calcium-aluminate cement.

Khoom nta
High-purity calcium aluminate cement minimizes impurities xws li silica thiab hlau oxide thiab muaj kev ruaj ntseg siab. Nws yog tsuas yog siv rau cov tsoos castables ua haujlwm ntawm 1800 degree. Nws muaj zog durability, zoo hluav taws kub tsis kam thiab kev tsim kho kev ua tau zoo, thiab zoo heev kub burst kuj.
Qib siab calcium aluminate castables cement nrog cov ntsiab lus alumina ntawm kwv yees li 80% thiab cov khoom siv ua haujlwm siab. Cov dej ntxiv yog me me, tab sis nws qhia tau hais tias muaj fluidity, siab zog thiab kev tsim kho zoo heev. Kev ruaj ntseg tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab pab txhim kho cov tshuab thiab txhim kho kev tsim kho. Feem ntau yog siv rau kub refractory castables, xws li ladles.
Nws yog siv nyob rau hauv rotary kilns thiab muaj kev tsim kho zoo heev thiab lub zog siab. Nyob rau tib lub sijhawm, nws qhov kub thiab txias flexural lub zog thiab kub flexural zog yog siab dua li lwm cov calcium aluminate castable cements. Vim nws yog nplua nuj nyob rau hauv calcium monoaluminate (CA) thiab calcium disaluminate (CA2), nws yog dav siv nyob rau hauv high-tech refractory cov ntaub ntawv, xws li tsawg cement castables thiab ultra-low cement castables.
Calcium aluminate cement nrog cov ntsiab lus alumina ntawm kwv yees li 71% yog tsim los muab cov khoom siv kho kom ruaj khov, zoo heev maneuverability, thiab ruaj khov siv lub sij hawm nyob rau hauv siab thiab tsis kub. Nws tsis muaj cov organic additives, yog li nws tsim nyog rau ultra-low cement castables thiab low-water castables, thiab muaj kev tsim kho zoo.
Cov khoom siv
1. Furnace Repairs: Refractory Calcium aluminate MAAs yog qhov kev daws teeb meem rau kev kho cov kab hluav taws xob thiab rov ua kom lawv cov khoom siv hluav taws xob ua kom sov, ua kom lub neej ntev ntawm lub cub tawg thiab tswj kev ua haujlwm zoo.
2. Kiln Linings: Nws yog dav siv nyob rau hauv kev tsim kho thiab kho cov qhov cub hauv ob sab phlu, muab cov cua sov kom zoo thiab ua kom muaj qhov kub thiab txias sib xws rau cov khoom tsim tawm.
3. Incinerator Linings: Cov cement no ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob txhim khu kev qha, tiv thaiv ib puag ncig corrosive thiab kub kub ntawm cov txheej txheem pov tseg.
4. Boiler Repairs: Siv rau kev kho cov boiler linings, cov cement muab kev tiv thaiv kev kub nyhiab, ua kom cov cua sov hloov tau zoo thiab kev ua haujlwm ruaj khov boiler.
5. Steel Ladle Maintenance: Nws yog ib qho khoom siv tseem ceeb rau kev tswj thiab kho steel ladles, qhov twg molten hlau thiab slag exposure xav tau superior refractory zog.
6. Chimney Lining: Refractory Cement yog siv rau hauv kev tsim kho thiab kho cov chimneys, muab cov cua sov ua haujlwm zoo thiab kev tiv thaiv tshuaj tiv thaiv rau emission tswj.
