Mea hana kiʻekiʻe kiʻekiʻe Anhydrous Borax / Sodium tetraborate / Sodium Borate cas 1330-43-4
Ua kapa ʻia hoʻi ʻo Anhydrous Borax ʻo sodium tetraborate, alpha orthorhombic crystal heheʻe kiko 742.5 ℃,
ʻO ka nui o ka 2.28g/cm3, ka helu heheʻe o ke kristal β orthorhombic he 664℃. ʻO ka nui o ka 2.75, he kristal keʻokeʻo ke ʻano.
a i ʻole ke aniani kala ʻole e like me ke aniani, hygroscopicity ikaika, hiki ke hoʻoheheʻe ʻia i ka wai, hoʻoheheʻe mālie ʻo Glycerin i loko o ka methanol e hana i kahi hopena me ka nui o 13-16%. He alkaline nāwaliwali kona hopena wai a ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waiʻona.
ʻO ka Borax Anhydrous kahi mea anhydrous i loaʻa ke hoʻomehana ʻia ka borax i 350 ~ 400 ℃, Ke kau ʻia i ka lewa, hiki iā ia ke omo i ka makū a lilo i borax decahydtate a i ʻole borax pentahydrate.
HOʻOMANAʻO: He kristal paʻa ka Borax ma lalo o nā kūlana mālama maʻamau a ʻaʻole ia e pane i ke kemika, akā inā loaʻa
pulu, e hoʻokuʻu ia i kahi koena o ka wela me ka wai e hana i ka borax decahydrate, no laila pono e mālama pono ʻia a ʻaʻole e hōʻike ʻia i ka makū a i ʻole ka mahana, i kahi ʻano e loli nei, inā ʻaʻole e hōʻuluʻulu. No laila, pono e hōʻoia i ka hoʻopili maikaʻi ʻana.
1. ʻO nā waiwai ʻē aʻe o ka borax anhydrous ua like ia me ka borax
2. Hoʻohana ʻia ka borax anhydrous no ke aniani kiʻekiʻe, glaze, flux Welding, nā metala non-ferrous a me nā fluxes alloy, etc...
3. ʻO ka borax anhydrous ka mea maka kumu no ka hoʻomākaukau ʻana i nā hui i loaʻa ka boron. Aneane hiki ke hana ʻia nā hui āpau i loaʻa ka boron mai ka borax.

A i ʻole hiki ke hoʻopilikino ʻia e like me nā pono o ka mea kūʻai aku
Pono ka mālama ʻana ma kahi anu, maloʻo a me ka ea.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
