Saxanka dhoobada malabka ee shubka iyo shaandhada gaaska
Shaandheeyaha dhoobada malabka ah ayaa lagu dabaqaa sifaynta dareeraha birta ah, waxaa lagu sameeyaa walxo dhoobo ah ama dhoobo cordierite ah.Iyada oo leh qaab dhismeedka daloolada toosan ee cufan ee gaarka ah, iska caabin shoog kulayleed oo aad u fiican, xoog sare, porosity sare iyo aag gaar ah.Taas oo lagu wanaajinayo xayeysinta iyo qabashada awoodda wasakhda yaryar, si looga takhaluso wasakhda aan birta ahayn iyo gaasta, nadiifinta dareeraha birta, ka dhigo dareeraha birta mid joogto ah oo yareeya vortex-ka.Ma aha oo kaliya in ay yarayso tusmada cilladaysan ee wax shubista, waxay dheeraysaa nolosha shaqada ee wax shubista waxayna yaraynaysaa kharashka wax shubista, laakiin sidoo kale waxay hagaajinaysaa awoodda makaanikada iyo tayada muuqaalka muuqaalka.
filtarka malabka dhoobada ah ayaa si weyn loogu dabaqaa dhirta birta ah ee shubka iyo abuurka, sida birta, birta, naxaasta iyo aluminium, iwm. Waxay leedahay xoojinta farsamada sare iyo kulaylka, ka saarta nijaasta birta, qashinka refractory, daawaha refractory adag iyo sinter dareeraha birta dhalaalay.

1. Iska caabin shoog kulayl oo heer sare ah.
2. Nashqadaha gacanta ee gaarka ah waxay sameeyaan dareere bir ah oo yareeya wareegga wareegga waxayna yareeyaan xumboyada tuurista.
3. Dhimashada saxda ah ee extrusion waxay ka dhigtaa tayada badeecada mid aad u deggan oo joogto ah.
4. Saamaynta shaandhada cad.
5. Hagaajinta wax qabadka dusha sare ee wax shubista iyo hagaajinta cufnaanta shubista.
6. Hagaajinta qaab dhismeedka birta iyo tayada ayaa kordhisa nolosha shaqada ee shubista.
7. Degganaanshiyo kiimikaad oo wanaagsan, oo aanay saamaynin biraha dhalaalay, wax isbeddel ah kuma samaynin kiimikaadkeeda.
8. Cabbirka saxda ah waxaana loo isticmaali karaa khadka wax soo saarka qalabka dhejinta shaandhada tooska ah.
