Tsawg cement castable yog ib hom khoom siv refractory, uas tuaj yeem ua tau raws li qhov xav tau ntawm qhov siab kub. Nws muaj cov yam ntxwv ntawm kev kub siab, siab lub zog, thiab kev kub siab. Thaum nws siv, nws yuav tsum raug ua haujlwm hauv tus qauv kom tsis txhob muaj keej. Tsawg cement castable muaj cov txheej txheem tsim khoom nruj thiab kev tsim ua raws li kev xav tau, thiab ntau yam tuaj yeem cuam tshuam nws txoj kev ua tau zoo. Cov tshooj lus hauv qab no nthuav qhia cov yam ntxwv ntawm Tsawg Cement Castable thiab cov yam ntxwv uas cuam tshuam rau kev ua haujlwm ntawm Low Cement Castable.
, Cov yam ntxwv ntawm cov cement tsawg dua
1. Qhov zoo ntawm koj qhov tsawg ntawm cov cement castable yog nws lub compactness thiab lub zog siab, uas coj cov txiaj ntsig rau nws siv. Tab sis nws coj teeb meem rau ci, uas yog, kev ci tsis tsim nyog, yooj yim rau tev lossis tawg. Yog li ntawd, nws yog qhov tseem ceeb heev uas yuav tsum ua kom tsim nyog lub hauv paus ci thiab siv cov khoom tawg zoo-pov thawj admixture, thiaj li ua rau cov dej ntsiab lus ntawm qhov refractory castable forming hnyav. Txoj kev tshem tawm tau zoo thiab tsis ua kev phiv tshuaj.
2. Tsawg cement castable yog ib hom kev lag luam siab thev naus laus zis tsim los ntawm cov castable zoo los ntawm kev siv rheological txoj kev xav, feem ntau kev cog lus cog pob khoom thiab ultra-nplua hmoov tshuab. Nws muaj cov yam ntxwv ntawm qis porosity, pore me me loj, loj ntom ntom ntom nti, zoo ntim ruaj khov, siab zog thiab dej me me. Nws ua tiav dhau tus yam ntxwv uas lub zog ntawm nquag tuaj yeem txo tau qis dua ntawm 800-1200 ℃.
3. Txawv sib txawv ntawm cov zoo tib yam refractory castable, qhov tsawg ntawm cov cement thiab ultra-low Cement Castables hloov feem lossis feem ntau ntawm cov calcium aluminate MAAs nrog cov tshuaj lom neeg muaj pes tsawg leeg ua cov khoom siv tseem ceeb ntawm cov castable, lossis zoo sib xws ultra-nplua hmoov, thiab ntxiv ib me me ntawm cov khoom tawg (dej tso tawm) thiab ib qhov nqi ntawm tso cov coagulant. Cov cementless castable tag yog sib txuas nrog ultrafine hmoov lossis oxide sol.
、 Qhov cuam tshuam cuam tshuam rau cov khoom ntawm cov cement qis dua
1. Superfine hmoov: superfine hmoov yog tus ncej txhawm rau txiav txim siab qhov kev ua haujlwm ntawm cov cement qis refractory castable, tuaj yeem hais tau yam tsis muaj exaggeration. Yog tsis muaj superfine hmoov, tsis muaj qis cement series refractory castable. Nyob rau hauv no hom refractory castable, superfine hmoov tsuas yog ua lub luag haujlwm ntawm dispersion accelerator thiab qauv densifier.
2. Aluminate xis mas: muaj ntau ntau yam ntawm aluminate xis mas, thiab lawv muaj qhov sib txawv. Yog li ntawd, cov khoom ntawm cov cement tsawg refractory castable npaj los ntawm ntau hom kuj sib txawv. Raws li rau qhov nyiaj ntawm aluminate xis mas, txaus chav kub lub zog muaj peev xwm ua kom tau raws li cov kev xav tau ntawm kev ua haujlwm ntawm formwork tshem tawm lossis nqa ntawm cov cement qis refractory castables.
3. Refractory orthopedics: hauv kev npaj ntawm cov cement tsawg refractory castables, cov refractory cov sib cais feem ntau tsis siv cov khoom sib tsoo, tab sis siv cov qib muaj ntau qib kev sib tw. Cov yam ntxwv ntawm qis cement refractory castables yog qhov sib txawv nrog ntau yam sib txawv ntawm refractory orthopedics. Txawv sib txawv ntau yam ntawm refractory orthopedics muaj sib txawv compressive zog ntawm castables.
4. Kev siv dej: kev siv dej ntawm kev siv tsawg ntawm cov cement refractory castables yog tib yam li lwm qhov ntawm lwm cov nqaim refractory. Ntawm qhov ua kom paub tseeb tias kev ua haujlwm ntawm kev sib tov, kev haus dej tsawg dua, ua kom zoo dua. Nyob rau hauv txoj kev no, tom qab castable yog tawv, qhov porosity yog tsawg dua thiab qhov porosity yog txo. Qhov kev hloov ntawm lub koom haum qauv me me, thiab qhov kev sib zog yuav nce.
