Chaw tsim khoom zoo Anhydrous Borax / Sodium tetraborate / Sodium Borate cas 1330-43-4
Anhydrous Borax tseem hu ua sodium tetraborate, alpha orthorhombic crystal melting point 742.5 ℃,
Qhov ceev 2.28g/cm3, β orthorhombic siv lead ua melting point 664 ℃. Qhov ceev 2.75, tsos yog siv lead ua dawb
los yog xim tsis muaj iav zoo li siv lead ua, muaj zog hygroscopicity, soluble hauv dej, Glycerin maj mam yaj hauv methanol los tsim cov tshuaj nrog qhov concentration ntawm 13-16%. Nws cov kua dej yog weakly alkaline thiab insoluble hauv cawv.
Anhydrous Borax yog ib yam khoom anhydrous tau los ntawm borax raug cua sov rau 350 ~ 400 ℃, Thaum muab tso rau hauv huab cua, nws tuaj yeem nqus cov dej noo thiab ua borax decahydtate lossis borax pentahydrate.
LUS CEEV: Borax yog cov siv lead ua ruaj khov nyob rau hauv cov xwm txheej khaws cia ib txwm thiab yuav tsis ua rau muaj kev sib xyaw ua ke, tab sis yog tias nws tau txais
ntub dej, nws yuav tso tawm ib qho me me ntawm cua sov nrog dej los tsim cov borax decahydrate, yog li nws yuav tsum tau khaws cia kom zoo thiab tsis txhob raug rau qhov av noo lossis kub, nyob rau hauv ib puag ncig hloov pauv, txwv tsis pub nws yuav agglomerate. Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej tias cov ntim khoom zoo.
1. Lwm yam khoom ntawm anhydrous borax zoo ib yam li borax
2. Anhydrous borax yog siv rau cov iav zoo, glaze, Vuam flux, cov hlau tsis yog ferrous thiab alloy fluxes, thiab lwm yam ...
3. Cov borax uas tsis muaj dej yog cov khoom siv tseem ceeb rau kev npaj cov tshuaj uas muaj boron. Yuav luag txhua cov tshuaj uas muaj boron tuaj yeem ua los ntawm borax.
