Lub ntsiab lus ntawm kev hloov pauv uas tsis hloov pauv

Cov khoom siv hluav taws xob tsis zoo: Cov khoom siv refractory tsis zoo yog sib xyaw ua ke ntawm cov khoom sib xyaw ua ke, hmoov, cov ntawv nplaum lossis lwm yam ntxiv hauv qee qhov kev faib ua feem, thiab tuaj yeem siv ncaj qha lossis sib xyaw nrog cov kua tsim nyog. Hauv lwm lo lus, cov khoom siv hluav taws xob yog ib yam tshiab ntawm cov khoom siv hluav taws xob uas tsis muaj calcination, thiab nws cov refractoriness tsis tsawg dua 1580 ° C.

Hmoov: tseem hu ua hmoov zoo, hais txog ib qho ntawm cov txheej txheem hauv cov qauv ntawm cov khoom siv ua kom tsis zoo nrog cov khoom me me tsawg dua 0.088mm, uas ua raws li kev sib txuas ua ke sib sau ua ke ntawm qhov kub kom tau txais lub cev thiab cov yam ntxwv zoo thiab ua tau zoo. Cov hmoov zoo tuaj yeem ntim cov pores ntawm qhov sib sau ua ke, muab faib lossis txhim kho kev ua tiav thiab ua kom ntom ntom ntawm cov khoom siv tsis zoo.

Aggregate: hais txog cov khoom me me uas muaj qhov loj me me ntau dua 0.088mm. Nws yog cov khoom siv tseem ceeb hauv cov qauv ntawm amorphous refractories thiab ua lub luag haujlwm ntawm pob txha. Nws txiav txim siab lub cev thiab cov cuab yeej muaj zog thiab cov khoom kub-kub ntawm cov khoom siv ua kom tsis muaj zog, thiab tseem yog lub hauv paus tseem ceeb rau kev txiav txim siab cov khoom siv thiab cov ntawv thov.

Binder: hais txog cov khoom siv uas sib cog ua ke cov khoom sib xyaw ua ke thiab hmoov ua ke thiab nthuav tawm lub zog tshwj xeeb. Binder yog ib feem tseem ceeb ntawm cov khoom siv ua kom tsis muaj zog thiab tuaj yeem siv rau cov khoom tsis huv, cov organic thiab cov khoom sib xyaw. Cov ntau yam tseem ceeb yog cov cement, iav dej, phosphoric acid, sol, resin, av nplaum thiab qee cov hmoov zoo heev.

Ntxiv: Nws yog cov khoom siv uas tuaj yeem txhim kho kev sib koom ua ke thiab txhim kho kev ua tiav ntawm qib matrix. Nws yog ib yam ntawm cov khoom siv hluav taws xob sib xyaw, cov khoom siv yooj yim uas tsim los ntawm cov hmoov refractory thiab cov phau ntawv, nws tseem hu ua tshuaj ntxiv. Xws li cov yas yas, cov tseev kom muaj, cov khoom siv rov qab, cov khoom siv hlawv, cov tshuaj nthuav dav, thiab lwm yam.

Ib qho ntxiv, rau qhov zoo ntawm cov hmoov, nws tau teev tseg tias qhov loj me me tsawg dua 5μm rau hmoov zoo, thiab tsawg dua 1μm rau ultrafine hmoov.
