Cov khoom siv refractory
Kev piav qhia txog khoom
Cov khoom siv refractoryyog cov khoom sib xyaw ua ke ntawm cov khoom siv refractory, hmoov thiab cov khoom khi. Tom qab ntxiv dej lossis lwm yam kua, lawv tsim nyog rau kev tsim kho los ntawm kev nchuav thiab kev co. Lawv kuj tuaj yeem ua prefabricated rau hauv cov khoom prefabricated nrog cov duab thiab qhov ntau thiab tsawg tshwj xeeb rau kev tsim kho ntawm cov khoom siv cua sov industrial. Txhawm rau txhim kho cov khoom siv lub cev thiab tshuaj lom neeg thiab kev ua haujlwm ntawm cov khoom siv refractory castables, cov khoom sib xyaw kom haum feem ntau ntxiv, xws li cov yas, cov khoom tawg, cov khoom ua kom nrawm, cov khoom ncua, cov neeg sawv cev nthuav dav, cov neeg sawv cev debonding-gelling, thiab lwm yam. Tsis tas li ntawd, rau cov khoom siv refractory castables siv rau hauv thaj chaw uas muaj zog loj lossis muaj zog thermal shock, yog tias ntxiv cov hlau tsis xeb fiber ntau, qhov tawv ntawm cov khoom yuav nce ntxiv ntau. Hauv cov khoom siv insulating refractory castable, yog tias ntxiv cov inorganic fibers, nws tsis tsuas yog txhim kho qhov tawv, tab sis kuj pab txhim kho nws cov khoom siv thermal rwb thaiv tsev. Txij li thaum cov khoom siv yooj yim ntawm cov refractory castables (xws li aggregates thiab hmoov, admixtures, binders thiab admixtures), coagulation thiab hardening txheej txheem, kev tsim kho, thiab lwm yam, zoo ib yam li cov pob zeb hauv kev tsim kho vaj tse, nws tau raug hu uacov pob zeb ua kom tsis kub.
