Kubbada dhoobada (sidoo kale loo yaqaan kubbadda taageerada, kubbadda aan shaqaynayn iyo warbaahinta taageerada kicinta) waxay ahaayeen qayb aad muhiim u ah geeddi-socodka kicinta ee warshadda sifaynta, habaynta gaaska iyo warshadaha batroolka.Shaqadeeda ugu weyni waa in ay u dhaqanto sida wax baakadaha iyo isla markaana ay taageerto sariirta kicinta si ay uga hortagto horumarka ama luminta maaddooyinka kiciya ama adsorbent ee ka hooseeya maraakiibta reactor sababtoo ah cadaadiska sare iyo heerkulka gudaha maraakiibta reactor inta lagu jiro hawlgalka .Kubadda dhoobada waxay la timid dhowr cabbir oo kala duwan, kuwaas oo ah 1/8 ", 1/4", 3/8", 1/2", 3/4", 1", 1¼", 1½", 2" .Baaxadda waxaa loo habeeyay lakabka sare iyo hoose ee markabka, oo leh cabbirro kala duwan oo kubbadda dhoobada ah.
Kubadda Alumina Sare 99% waxay la mid tahay Denstone 99 Media Support.Waxay ku jirtaa halabuurka kiimikada99+% alfa alumina iyo ugu badnaan 0.2wt% SiO2.Sababtoo ah maadada alumina ee sarreeya iyo silica hoose (SiO2), waa wax soo saar aad u fiican oo ku habboon heerkulka sare iyo codsiyada uumiga, sida dib-u-habeeynta sare ee farsamaynta ammonia, halkaas oo silica leached ay dabooli doonto qalabka hoose ama ay xumaato sariirta kicinta.
99% High Alumina Ball waxay leedahay sifooyin kulayl aad u wanaagsan, oo leh cufnaanta sare ee heerkulka sare ee 1550 ℃, sidoo kale waa doorasho wanaagsan oo haynta kulaylka ama warbaahinta dheellitirka.
Iska caabbinta kiimikaad ee sare, waxay ku habboon tahay codsiyada hababka olefin, sida qalajiyaasha ethylene, halkaasoo ay jirto dhibaatada polymerization.
