Nang woi awn ai Boehmite jaw ai wa
Luoyang Zhongchao New Material Co., Ltd. (ndai kaw nna "ZC-TECH" ngu nna shamying na) gaw Miwa mung, Henan mungdaw, hpaga lam ginra hta nga ai rai nna, lamu ga eka 60 jan kaba ai shara kaw nga ai. 2003 ning hta hpaw ninghtan da ai, grup yin hpe n hkra ai hte n san seng ai arung arai nnan ni hpe hpaji ninghkring ni a sawk sagawn ai lam, galaw shapraw ai lam, dut shabra ai lam ni hpe hpawng de da ai hpaga hpung langai rai nga ai. Shi a madung galaw shapraw ai arung arai ni gaw, aluminum hpe madung tawn ai super fine wan hkru ai arung arai hte magnesium hpe madung tawn ai super fine wan hkru ai arung arai, laksan alumina, shingnip shingna alumina, boehmite, rawt jat galu kaba wa ai nlung n-gun, electronic n-gun hte kaga n-gun n rawng ai arung arai ni rai nga ai.
Hpyen n-gun law ai, wan n-gun n law ai, halogen-n lawm ai application ni zawn re ai laksan ra kadawn ai lam ni a matu laksan galaw da ai formula design ni hpe jaw u.
Boehmite arung arai ni
Chemical atsam ningja ni
A hpraw; n-gup magap-hkum hkrang; a=0.286 nm, b=1.2227nm, c=0.380nm; n-gun ja ai gaw 3.5–4 Mohs; 200℃–250℃hta hydroxide nhprang dat ni a hka n-gun hpe n-gun dat ai hku nna lu la ai.
Boehmite gaw, nlung n-gun rawng ai ( -AlO(OH)) nlung rai nna, nlung n-gun rawng ai bauxite a daw langai mi rai nga ai. Orthorhombic system hta lawm nna, n-gun rawng ai hkrang masa nga ai. Langai hpra a npawt nhpang npawt nhpang hta, oxygen ion ni hpe octahedron a npawt nhpang ni hta cubic close-pack galaw nna, aluminum ion ni hpe octahedron a lapran kaw tawn da nna, npawt nhpang lahkawng lang -pack galaw da ai. , hydroxide radical ni gaw n-gup magap npu kaw nga ai rai nna, n-gup magap ni hpe hydrogen n-gun hte matut da ai.
Hkum hkrang atsam ningja ni
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), Shadawn shadang (1 – 2) hpe tsun ai. Dai hte maren, alumina hka ja ai shara ni gaw, bauxite amyu langai hpe laksan galaw na matu galaw da ai. Boehmitic bauxites ni hpe 'high temperature' digestion masa ni hpe jai lang nna galaw shapraw ai (boehmite hpe bai lu la na matu) theory hku yu yang boehmitic bauxite hpe n-gun n law ai plant hta galaw mai ai rai yang, boehmite madang ni gaw n-gun n law ai rai yang, ndai boehmite n-gun n law ai raitim, n-gun n rawng ai hka htung hta galaw mai ai.
Al(OH)3 (s) + NaOH (aq)<=>Naal(OH)4 (aq) (1)
AlOOH (s) + H2O (l) + NaOH (aq)<=>Naal(OH)4 (aq) (2)
Boehmite hpe jai lang ai
Aluminum galaw shapraw ai
Boehmite gaw Bayer process hta shawng nnan na n-gun rai nna, dai hpe n-gun dat nna alumina hpe shapraw ai. Dai alumina hpe n-gun dat nna aluminum n-gang hpe shaw la ai. Boehmite a san seng ai lam gaw aluminum galaw shapraw ai atsam hte hkam kaja lam hpe hkrak hkra hkra machyi shangun ai majaw, ahkyak ai raw material langai byin tai wa ai.
Catalysts & wan sau tsi ni
Catalytic lang ai hta, boehmite gaw madi shadaw ai arung arai langai hku nna magam gun nga ai. Shi a ntsa n-gun kaba ai hte n-gun n-gun n-gun n-rawng ai majaw, grau nna, n-gun ja ai n-gun ja ai hte petrochemical galaw ai lam ni hta, catalyst a shamu shamawt lam hpe jat ya ai. Ndai lam gaw, grau kaja ai chemical reaction ni hpe galaw ya lu nna, bungli galaw ai manu hpe mung shayawm ya lu ai.
Ceramics & wan n hkru ai arung arai ni
N-gun ja ai-n-gun hpe hkam sharang lu ai boehmite powder ni hpe n-gun n-rawng ai lung seng hte ceramic arung arai ni hpe galaw shapraw ai hta lang ma ai. Ndai arung arai ni gaw wan wut ai shara, wan wut ai shara, wan wut ai shara ni hta grai katsi ai hpe hkam jan lu ai majaw, ngang grin ai hte shim lum ai.
Polymers hte hpawng chyawm ai arai ni
Boehmite hpe polymer matrices ni hta bang nna, nbung n-gun hpe grau kaja hkra galaw ya ai. Ndai application gaw nbungli hte mawdaw galaw ai zawn re ai bungli ni hpe akyu jaw ai, dai shara ni hta n-gun n law ai raitim, ngang grin ai arung arai ni ra kadawn nga ai.
Wan jak hte n-gun shayawm ai
Boehmite hpe n-gun n-gun n-rawng ai majaw, electronic arung arai ni hta mung, dielectric arung arai hku nna mung jai lang ma ai. Wan n-gun npu hta shi a ngang grin ai lam gaw, jak ni hta aten galu-galaw lu na matu madi shadaw ya ai.
Htaw wa htaw sa lam:-hkrit tsang hpa n re ai arung arai ni, raitim, htaw sa ai shaloi, hka n htum hkra, katsi ai hku tawn da nna, pat da ra ai.
Gunrai tawn da shara:Hkring ai hte nbung n-gun rawng ai shara hta tawn da u, o .
