Lau Fa'atau Boehmite Sili
Luoyang Zhongchao New Material Co., Ltd. (o lo'o ta'ua mulimuli ane i le "ZC-TECH") o lo'o i totonu o Industrial Cluster Zone, Henan Province, Saina, e aofia ai se eria e sili atu i le 60 eka. Fa'atūina i le 2003, ose atina'e e tu'ufa'atasia su'esu'ega fa'apolofesa ma atina'e, gaosiga, ma fa'atauga o mea fou e fa'alelei ma le fa'aleagaina- O ana oloa autu o le alumini e fa'avae i luga o le afi tele -mea fa'alumaina ma le magnesium e fa'avae i luga o le afi sili ona lelei-mea fa'agata, alumina fa'apitoa, alumina spherical, boehmite, sima fa'aola, sima fa'aeletonika ma isi mea fa'apitoa.
Tuuina atu ni mamanu fa'apitoa mo mana'oga fa'apitoa e pei ole fa'atumu maualuga, maualalo le asu, ma mea fa'aoga e leai se totogi.
Meatotino Boehmite
O mea tau vailaau
Lanu pa'epa'e; pito -rhomb; a=0.286 nm, b=1.2227nm, c=0.380nm; maaa e 3.5–4 Mohs; maua i le hydrothermal tali o slurries hydroxide i 200 tikeri –250 tikeri.
O le Boehmite o le alumini oxide hydroxide (-AlO(OH)) minerale, o se vaega o le bauxite ole alumini. E a'afia i le orthorhombic system ma o lo'o i ai se fausaga fa'apipi'i. I vaega fa'avae ta'itasi ta'itasi, o ion okesene o lo'o fa'atulaga i kupita pupuni-o lo'o fa'apipi'i i tumutumu o le octahedron, ma o ion alumini o lo'o tu i le ogatotonu o le octahedron e fai ai se fausaga fa'alua-lua. , o vailaʻau o le hydroxide o loʻo i luga o le pito i luga o le fausaga faʻapipiʻi, ma o loʻo fesoʻotaʻi faʻapipiʻi e fusi hydrogen.
Meatotino faaletino
The most important aluminous minerals in bauxite are gibbsite (Al(OH)3), boehmite (AlO(OH)) and diaspore (AlO(OH)), however gibbsite requires lower digestion temperature to be dissolved (typically ~145oC) as compared to boehmite and diaspore (typically >240 oC), Fa'atatau (1 – 2). O le mea lea, e masani lava ona mamanuina fale gaosi alumina e faʻatautaia faapitoa se tasi ituaiga o bauxite. E ui o le boehmitic bauxite e masani lava ona faʻaaogaina e ala i le 'maualuga o le vevela' tulaga faʻamaʻi (e toe maua ai le boehmite) i le talitonuga o le boehmitic bauxite e mafai ona gaosia i totonu o se fale maualalo vevela e aunoa ma se aʻafiaga o le faʻagasologa pe a fai e lava le maualalo o le boehmite, e ui lava e le o faʻamavaeina lenei mea boehmite, faʻateleina le aofaʻi o totoe i le faʻamalamalamaga.
Al(OH)3 (s) + NaOH (aq)<=>NaAl(OH)4 (aq) (1)
AlOOH (s) + H2O (l) + NaOH (aq)<=>NaAl(OH)4 (aq) (2)
Fa'aaogaina o Boehmite
Gaosi alumini
O le Boehmite o se faʻamuamua i le Bayer process, lea e faʻapipiʻiina e maua ai le alumina. O lenei alumina e faʻafefeteina e aveese mai ai le uʻamea alumini. O le mama o le boehmite e aʻafia tonu ai le lelei ma le lelei o le gaosiga o le alumini, ma avea ai ma mea mataʻutia.
Catalysts & petrochemicals
I faʻamatalaga faʻapitoa, o le boehmite e avea o se mea lagolago. O lona maualuga maualuga ma le mautu o le vevela e faʻaleleia ai le gaioiga faʻamalosi, aemaise i le faʻamamaina ma le faʻaogaina o le suauu. O le mea lea e maua ai le sili atu ona lelei o gaioiga fa'a-kemikolo ma fa'aitiitia ai tau o galuega.
Ceramic & refractoryes
O pa'u boehmite maualuga-e fa'aogaina i le gaosiga o piliki fa'asa'o ma vaega sima. O mea nei e tetee atu i le vevela tele i totonu o ogaumu, kilns, ma reactors, faʻamautinoa le tumau ma le saogalemu.
Polymers & composite
Boehmite ua tuʻufaʻatasia i polymer matrices e faʻaleleia ai le mautu o le vevela ma le malosi faʻainisinia. O lenei talosaga e manuia ai pisinisi e pei o le aerospace ma le gaosiga o taavale, lea e manaʻomia ai mea mama ma umi.
Fa'aeletonika & fa'amama
Ona o ana mea faʻapipiʻi, o loʻo faʻaaogaina le boehmite i mea faʻaeletoroni ma o se mea e faʻaaogaina. O lona mautu i lalo o le mamafa o le eletise e mautinoa ai le umi-fa'atinoga i masini.
Felauaiga:O oloa e le -mata'utia, ae i le taimi o felauaiga ina ia aloese mai le susu, fa'amamago, fa'amaufa'ailoga.
Teuina:Teu i se nofoaga matutu ma fa'aalili, ae le o totonu ole o
