Soo saaraha tayada sare leh Anhydrous Borax/Sodium tetraborate/Sodium Borate cas 1330-43-4
Anhydrous Borax waxa kale oo loo yaqaan tetraborate sodium, alfa orthorhombic crystal point 742.5℃,
Cufnaanta 2.28g/cm3, β orthorhombic crystal barta dhalaalka 664℃. Cufnaanta 2.75, muuqaalku waa crystal cad
ama kareem aan midab lahayn oo muraayad u eg, hygroscopicity xoog leh, oo ku milma biyaha, Glycerin si tartiib ah u milmaan methanol si ay u sameeyaan xal leh fiirsashada 13-16%. Xalka aqueous waa alkaline daciif ah oo aan lagu milmi karin khamriga.
Anhydrous Borax waa walxo anhydrous ah oo la helo marka borax la kululeeyo ilaa 350 ~ 400 ℃, Marka la geliyo hawada, waxay nuugi kartaa qoyaan waxayna noqon kartaa borax decahydtate ama borax pentahydrate.
FIIRO GAAR AH: Borax waa crystals deggan marka lagu jiro xaaladaha kaydinta caadiga ah mana ka falcelin doonto kiimiko, laakiin haddii ay hesho
qoyan, waxay ku sii dayn doontaa raad kulaylka biyo si ay u soo saaraan borax decahydrate, sidaas darteed waxay u baahan tahay in si sax ah loo kaydiyo oo aan la kulmin huurka ama heerkulka, jawiga isbeddelaya, haddii kale way sii xumaanaysaa. Sidaa darteed, waa lagama maarmaan in la hubiyo baakadaha wanaagsan.
1. Astaamaha kale ee borax anhydrous waxay la mid yihiin borax
2. Anhydrous borax waxaa loo isticmaalaa galaas tayo sare leh, dhaldhalaalka, Welding flux, biraha aan birta ahayn iyo dareeraha daawaha, iwm.
3. Borax anhydrous waa alaabta ceeriin ee aasaasiga ah ee diyaarinta xeryahooda boron ku jira. Ku dhowaad dhammaan xeryahooda boron ku jira waxaa laga samayn karaa borax.
