Cov ntaub ntawv raw ntawm lub teeb yuag castables yog lub teeb yuag aggregates thiab hmoov ntxiv nyob rau hauv kev faib ua feem, thiab cov neeg sawv cev losis tswvyim dabtsi kuj ua ke nrog siab alumina cement. Kuj tseem muaj kev sib xyaw ua ke ntawm sodium silicate thiab phosphoric acid, tab sis tus nqi ntawm cov ntaub ntawv ntxiv rau lub teeb yuag castables yog qhov loj, thiab qhov feem pua ntawm cov dej ntxiv thaum lub sij hawm tsim kho kuj loj dua qhov hnyav castables.

Thaum siv lub teeb yuag refractory castables, nws yuav tsum tau muab sau tseg tias lub lag luam yuav tsum tau ua raws li cov kev cai ntawm cov lus qhia, tshwj xeeb tshaj yog sib tov piv, dej ntxiv, thiab lwm yam yuav tsum tau tswj kom raug. Tsis tas li ntawd, nws yog ib qho tsim nyog los tswj cov dej noo ntawm cov castable kom tsis txhob muaj cov kab nrib pleb thiab kev puas tsuaj rau cov castable los ntawm cov dej noo ntau dhau.

hom ntawm lub teeb yuag castable refractory

1. Lub teeb yuag mullite castable

Lub teeb yuag mullite castable yog ib yam khoom siv rwb thaiv tsev nrog lub teeb mullite ua cov khoom tseem ceeb. Nws yog feem ntau yog tsim los ntawm lub teeb yuag mullite particles, aluminate cement thiab lwm yam additives, thiab yog tsim los ntawm thermal rwb thaiv tsev txheej ntawm industrial kilns los ntawm kev sib tov thiab pouring.

2. Perlite hnav castable

Perlite refractory castables feem ntau haum rau qhov kub thiab txias ntawm 600 txog 900 degree. Kev siv Portland MAAs raws li kev sib khi ua tau raws li qhov yuav tsum tau ua ntawm lub qhov cub. Thaum npaj, ntub cov perlite ua ntej thiab tom qab ntawd sib tov cov khoom xyaw. Do tusyees thiab ntxiv dej rau cov ntub dej sib tov. Thaum lub sij hawm molding, lub sij hawm vibration yuav tsum tau tswj los xyuas kom meej ntim ntim. Tom qab molding, natural curing yog ua rau 3 hnub. Kev kho cov dej noo tuaj yeem ua tau thaum qhov kub siab tshaj 25 degree.

3. Porous clinker hnav castable

Porous clinker lightweight castables feem ntau muab faib ua ob hom: av nplaum thiab siab alumina. Lawv qhov ntom ntom yog nyob nruab nrab ntawm 1.1 ~ 1.8g / cm3, thiab qhov kev pabcuam kub tuaj yeem ncav cuag 1300 degree thiab 1400 degree. Thaum npaj hom refractory castable no, cov khoom siv raw yuav tsum tau hnyav thiab sib xyaw raws li cov kev xav tau sib xyaw tshwj xeeb, thiab tom qab ntawd kev co lossis phau ntawv vibration molding yog siv. Tom qab ib hnub ntawm natural curing, cov pwm raug tshem tawm thiab kho ntxiv rau ob hnub. Tsis tas yuav tsum tau txau dej thaum lub sijhawm kho vim tias qhov sib xyaw dej ntim txaus kom ua tau raws li cov cement hydration xav tau.

4. Ceramsite hnav castables

Ceramsite lub teeb yuag castable yog cov khoom siv refractory tsim los ntawm cov khoom zoo shale ceramsite, refractory hmoov, binder thiab admixtures. Nws yog tus cwj pwm los ntawm qhov tsis tshua muaj siab, lub zog siab, kev hloov pauv me me, thiab thermal conductivity tsawg. Qhov no castable yog tsim rau nruab nrab thiab qis-kub cov khoom siv thermal, xws li petrochemical tubing cua sov rauv, thiab lwm yam, raws li cov ntaub ntawv zoo.

5. Vermiculite hnav castable

Qhov kev pabcuam kub ntawm vermiculite refractory castable yog 600 ~ 800 degree. Nws yog tus cwj pwm los ntawm kev ua haujlwm zoo thermal rwb thaiv tsev, khoom siv yooj yim, thiab tus nqi qis. Qhov kev npaj ntawm no castable yog tib yam li cov perlite refractory castable.
