Industrial Soda tshauv Sodium Carbonate
Lub teeb sodium carbonate yog dawb crystalline hmoov, hnyav sodium carbonate yog dawb zoo particle.
Kev lag luam sodium carbonate tuaj yeem muab faib ua: Kuv qeb hnyav sodium carbonate siv rau hauv kev lag luam thiab II qeb sodium carbonate rau kev lag luam, raws li kev siv.
Zoo stability thiab noo noo nqus.Haum rau flammable organic tshuaj thiab sib tov.Nyob rau hauv qhov sib raug zoo tis, thaum tig, nws yog feem ntau muaj peev xwm xav tias cov hmoov av tawg muaj peev xwm.
√ Tsis muaj ntxhiab tsw ntxhiab, me ntsis alkaline tsw
√ High boiling point, nonflammable
√ Siv nyob rau hauv ntau lub teb thiab muaj ntau yam kev siv

Tuam Tshoj Kev Lag Luam Kev Lag Luam Borax Anhydrous
Cov khoom ntawm anhydrous borax yog dawb crystals los yog tsis muaj kob iav crystals, lub melting point ntawm α orthorhombic siv lead ua yog 742.5 ° C, thiab qhov ceev yog 2.28;Nws muaj zog hygroscopicity, yaj nyob rau hauv dej, glycerin, thiab maj mam yaj nyob rau hauv methanol los ua ib tug tov nrog ib tug concentration ntawm 13-16%.Nws cov tshuaj aqueous yog qaug zog alkaline thiab insoluble hauv cawv.Anhydrous borax yog cov khoom tsis muaj dej uas tau txais thaum borax yog cua sov rau 350-400 ° C.Thaum muab tso rau hauv huab cua, nws tuaj yeem nqus dej noo rau hauv borax decahydrate lossis borax pentahydrate.
