Umhlinzeki Wakho Ohamba phambili we-Boehmite
I-Luoyang Zhongchao New Material Co., Ltd. (ngemuva kwalokhu ebizwa ngokuthi "ZC-}TECH") itholakala ku-Industrial Cluster Zone, eSifundazweni sase-Henan, e-China, ehlanganisa indawo engaphezu kwamahektha angu-60. Yasungulwa ngo-2003, iyibhizinisi elihlanganisa ucwaningo nokuthuthukiswa kochwepheshe, ukukhiqizwa, kanye nokuthengiswa kwezinto ezintsha ezilungele imvelo kanye nokungcola{6}}kwamahhala. Imikhiqizo yayo eyinhloko i-aluminium esuselwe kwi-super fine flame-izinto ezingaboli kanye ne-magnesium esekelwe ku-super fine flame{9}}izinto ezingabambeki, i-alumina ekhethekile, i-alumina eyindilinga, i-boehmite, izitsha zobumba ezithuthukisiwe, izitsha zobumba zikagesi nezinye izinto ezingaphili.
Nikeza ngemiklamo yefomula eyenziwe ngokwezifiso yezidingo ezikhethekile ezinjengokugcwalisa kakhulu, intuthu ephansi, ne-halogen{0}}izinhlelo zokusebenza zamahhala.
Izakhiwo ze-Boehmite
Izakhiwo zamakhemikhali
Okumhlophe; i-ortho-rhomb; a=0.286 nm, b=1.2227nm, c=0.380nm; ubulukhuni buyi-3.5-4 Mohs; kutholwe ukusabela kwe-hydrothermal ye-hydroxide slurries ku-200℃-250 degree.
I-Boehmite iyiminerali ye-aluminium oxide hydroxide (-AlO(OH)), ingxenye ye-aluminium ore bauxite. Ingokwesistimu ye-orthorhombic futhi inesakhiwo esinezingqimba. Kusendlalelo ngasinye sesakhiwo, ama-ion omoya-mpilo ahlelwa nge-cubic close-apakishwe kuma-vertices e-octahedron, futhi ama-ion e-aluminium atholakala phakathi nendawo ye-octahedron ukuze akhe uhlaka olukabili{4}}. , ama-radicals e-hydroxide atholakala ebusweni besakhiwo esinezingqimba, futhi izingqimba zixhunywe ngamabhondi e-hydrogen.
Izici ezingokomzimba
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), Izibalo (1 – 2). Kanjalo, izindawo zokucwenga ze-alumina zivame ukuklanywa ukucubungula uhlobo olulodwa lwe-bauxite. Nakuba ama-bauxite e-boehmitic ngokuvamile acutshungulwa kusetshenziswa izimo zokugaya 'zezinga lokushisa eliphezulu' (ukubuyisela i-boehmite) ngokombono i-boehmitic bauxite ingacutshungulwa endaweni yokushisa ephansi engenawo noma umthelela omncane wenqubo uma amazinga e-boehmite ayephansi ngokwanele, nakuba lokhu okuqukethwe kwe-boehmite kungancibilikisiwe, okwandisa inani lezinsalela ekucaciseni.
Al(OH)3 (ama) + NaOH (aq)<=>I-NaAl(OH)4 (aq) (1)
U-AlOOH (izi) + H2O (l) + NaOH (aq)<=>I-NaAl(OH)4 (aq) (2)
Ukusetshenziswa kwe-Boehmite
Ukukhiqizwa kwe-aluminium
I-Boehmite iyisandulela senqubo ye-Bayer, lapho ibalwa khona ukuze kukhiqizwe i-alumina. Le aluminium ibe isincibilikiswa ukuze kukhishwe insimbi ye-aluminium. Ukuhlanzeka kwe-boehmite kuthinta ngqo ukusebenza kahle kanye nekhwalithi yokukhiqizwa kwe-aluminium, okwenza kube impahla eluhlaza ebalulekile.
Ama-Catalysts nama-petrochemicals
Kuzinhlelo zokusebenza ze-catalytic, i-boehmite isebenza njengento yokusekela. Indawo yayo ephezulu kanye nokuzinza kokushisa kuthuthukisa umsebenzi we-catalyst, ikakhulukazi ezinqubweni zokucwenga kanye ne-petrochemical. Lokhu kubangela ukusabela kahle kwamakhemikhali kanye nokunciphisa izindleko zokusebenza.
Ceramics & refractories
{0}}Izimpushana ze-boehmite ezimelana nezinga lokushisa eliphezulu zisetshenziswa ekukhiqizeni izitini ezikhanyelayo nezinto zobumba. Lezi zinto ezisetshenziswayo zimelana nokushisa okudlulele eziko, kwiziko, nasezintweni ezishisayo, ziqinisekisa ukuqina nokuphepha.
Ama-polymers nama-composites
I-Boehmite ifakwe kumatrices e-polymer ukuze kuthuthukiswe ukuzinza okushisayo namandla emishini. Lolu hlelo lokusebenza luhlomula izimboni ezifana ne-aerospace kanye nokukhiqiza izimoto, lapho izinto ezingasindi kodwa eziqinile zibalulekile.
I-elekthronikhi & ukwahlukanisa
Ngenxa yezakhiwo zayo zokuvikela, i-boehmite isetshenziswa ezingxenyeni ze-elekthronikhi nanjenge-dielectric material. Ukuzinza kwayo ngaphansi kwengcindezi kagesi iqinisekisa{1}}ukusebenza okuhlala isikhathi eside kumadivayisi.
Ezokuthutha:Izimpahla okungezona-eziyingozi, kodwa ngesikhathi sokuthutha ukuze ugweme umswakama, zigcine zomile, zivaliwe.
Isitoreji:Gcina endaweni eyomile nengena umoya, hhayi ku-o
