Foundry xuab zeb yog siv los ua granular refractory khoom rau molding xuab zeb thiab core xuab zeb hauv foundry ntau lawm.Nyob rau hauv cov ntaub ntawv ntawm siv av nplaum ua ib tug molding xuab zeb daim ntawv cog lus, rau txhua tuj ntawm tsim nyog castings tsim, nws yog tsim nyog los ntxiv 1 tuj ntawm cov xuab zeb tshiab.Yog li ntawd, cov xuab zeb loj tshaj plaws yog siv hauv cov xuab zeb casting ntau lawm.
Nyob rau hauv lub xyoo pua 17th, Tuam Tshoj siv silica xuab zeb los ua molding khoom xws li moos, tsom iav, pots thiab artillery.Txawm li cas los xij, feem ntau ntawm cov xuab zeb no yog cov av nplaum uas muaj cov silica xuab zeb, uas yog cov xuab zeb roob thiab dej xuab zeb, uas muaj cov yas zoo dua thiab tuaj yeem siv ncaj qha los tsim cov pwm thiab cov cores.Tom qab cov castings nkag mus rau hauv kev lag luam loj, tshwj xeeb tshaj yog tom qab lub tshuab ua qauv, qhov sib xws ntawm cov av nplaum uas muaj cov silica xuab zeb tsis zoo, thiab qhov zoo ntawm cov xuab zeb molding yog qhov nyuaj rau kev tswj, uas tsis tuaj yeem ua raws li cov txheej txheem.Yog li ntawd, cov xuab zeb cog tau pib los cuam tshuam nrog ntuj silica xuab zeb los ntawm Scrubing, xaiv kom tau txais ntau hom silica xuab zeb.Tsis tas li ntawd, silica xuab zeb yog tsim los ntawm crushing silica.Nyob rau tib lub sijhawm, nws tseem nthuav dav daim ntawv thov thiab kev loj hlob ntawm ntau yam uas tsis yog-silicon resin xuab zeb qauv thiab cov txheej txheem ua cov txheej txheem, thiab tso siab rau cov kev xav tau ntau dua rau kev ua cov xuab zeb zoo, xws li cov hmoov tsis zoo, cov kev txwv me me, thiab qis dua. acid noj.Yog li ntawd, qee lub tebchaws uas tsis muaj cov xuab zeb zoo rau qhov loj ntawm cov xuab zeb kuj tau tsim silica xuab zeb flotation tshuab los txhim kho qib thiab zoo ntawm cov xuab zeb silica.

Foundry xuab zeb yuav tsum ua tau raws li cov cai hauv qab no: ① siab dua purity thiab huv si, noj silica xuab zeb ua piv txwv, xuab zeb rau cam khwb cia hlau yuav tsum tau SiO₂Cov ntsiab lus siab tshaj 90%, sintered cam khwb cia hlau qhov yuav tsum tau SiO₂cov ntsiab lus siab dua 97%;② siab kub tsis kam Degree thiab thermal stability;③ Tsim nyog particle zoo thiab particle muaj pes tsawg leeg;④ Tsis yooj yim doped los ntawm cov kua hlau;⑤ Pheej yig thiab yooj yim kom tau txais.
Txij li thaum xyoo 1951, Tuam Tshoj tau ua kev suav pej xeem ntawm cov khoom siv xuab zeb hauv kev ua tiav, tab sis nws yog nyob ze rau cov kab tsheb thauj mus los loj thiab cov nroog loj.Nyob rau hauv Zhelimeng, Inner Mongolia, lub ntuj silica xuab zeb reserves npaum li cas mus rau pua pua lab tons, thiab nws particle zoo yog ze rau lub voj voog, thiab SiO.₂cov ntsiab lus yog hais txog 90%, uas yog heev haum rau industrial casting.Lub hiav txwv xuab zeb ntawm Jinjiang, Dongshan, Fujian, SiO₂cov ntsiab lus yog 94 ~ 98%.Muaj ntau tus dej Quaternary thiab pas dej sedimentary silica xuab zeb hauv Duchang, Xingzi, Yongxiu County, Jiangxi Province.SiO₂cov ntsiab lus yog li ntawm 90%.Nws muaj nplua nuj thiab tsis yooj yim weathered sandstone nyob rau hauv Guangzhou thiab Hunan.Nws SiO₂Cov ntsiab lus yog siab dua 96%, uas tuaj yeem siv rau cov ntsiab lus hlau tsawg, tsawg alkaline oxides, cov khoom me me.
