Iibiyaha Boehmite ee hogaaminaya
Luoyang Zhongchao New Material Co., Ltd. (kadib loo tixraaco "ZC-TECH") waxa uu ku yaalaa Aagga Kutlada Warshadaha, Gobolka Henan, Shiinaha, oo daboolaya dhul dhan 60 acres. Waxaa la aasaasay 2003, waa shirkad isku xidha cilmi-baadhis xirfadeed iyo horumarin, wax-soo-saar, iyo iibinta deegaanka saaxiibtinimo iyo wasakh- walax cusub oo bilaash ah. Alaabooyinkeeda ugu muhiimsan waa aluminium ku salaysan ololka fiican- walxaha dib u dhigista iyo magnesium ku salaysan ololka fiican{9}} walxaha dib u dhigista, alumina khaaska ah, alumina wareega, boehmite, ceramics horumarsan, dhoobada elektarooniga ah iyo walxo kale oo aan dabiici ahayn.
Bixi nashqadaha caanaha ee shuruudaha gaarka ah sida buuxinta sare, qiiq yar, iyo halogen{0} codsiyo bilaash ah.
Guryaha Boehmite
Waxyaabaha kiimikada
Caddaan; ortho - ; a =0.286 nm, b=1.2227nm, c=0.380nm; adkaanta waa 3.5-4 Mohs; lagu helay falcelinta hydrothermal ee dareeraha hydroxide at 200 darajo -250 darajo.
Boehmite waa aluminium oxide hydroxide ( -AlO(OH) macdanta, qayb ka mid ah aluminium ore bauxite. Waxay ka tirsan tahay nidaamka orthorhombic waxayna leedahay qaabdhismeed lakabaysan. Lakab kasta oo hal dhisme ah, ions ogsijiin waxa lagu habeeyaa cubic dhow -oo laga soo buuxiyay cidhifyada octahedron, iyo aluminium aluminium waxay ku yaalaan bartamaha octahedron si ay u sameeyaan qaab-dhismeed labanlaab ah-. , radicals hydroxide waxay ku yaalaan dusha sare ee qaabka lakabka ah, iyo lakabyada waxaa ku xiran bonds hydrogen.
Tilmaamaha jirka
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), isla'egta (1 - 2). Sidaa darteed, sifayaasha aluminiumka waxaa badanaa loogu talagalay inay si gaar ah uga baaraandegaan hal nooc oo bauxite ah. Halka boehmitic bauxites inta badan lagu farsameeyo iyadoo la adeegsanayo xaaladaha dheefshiidka 'heerkulka sare' (si loo soo kabsado boehmite) aragti ahaan boehmitic bauxite waxaa lagu farsamayn karaa warshad heerkul hoose leh oo aan lahayn ama saameyn habka ugu yar haddii heerarka boehmite ay si ku filan u hooseeyaan, inkasta oo maaddadan boehmite aan la milmin, kordhinta qadarka haraaga si loo caddeeyo.

Isticmaalka Boehmite
Wax soo saarka aluminium
Boehmite waa horudhac geeddi-socodka Bayer, halkaas oo laga soo saaro alumina. Aluminnadan ayaa markaa la dhalaaliyaa si loo soo saaro birta aluminiumka. Nadiifinta boehmite waxay si toos ah u saameyneysaa waxtarka iyo tayada wax soo saarka aluminium, taasoo ka dhigaysa alaab cayriin ah oo muhiim ah.
Katalisyada & kiimikooyinka petrochemicals
Codsiyada catalytic, boehmite waxay u adeegtaa sidii qalab taageero ah. Baaxdeeda sare iyo xasilloonida kulaylku waxay kor u qaadaysaa dhaqdhaqaaqa kicinta, gaar ahaan sifaynta iyo hababka batroolka. Tani waxay keenaysaa falcelin kiimiko oo hufan iyo kharashyada hawlgelinta oo yaraada.
Ceramics & refractories
Budada boehmite ee heerkulkoodu sarreeyo-waxaa loo isticmaalaa samaynta lebenka soo celinaya iyo qaybaha dhoobada. Qalabkani waxay u adkeystaan kulaylka ba'an ee foornooyinka, kilns, iyo reactors, iyagoo hubinaya adkeysiga iyo badbaadada.
Polymers & isku dhafan
Boehmite waxaa lagu daray maadooyinka polymer-ka si loo hagaajiyo xasilloonida kulaylka iyo xoogga farsamada. Codsigan wuxuu faa'iido u leeyahay warshadaha sida hawada hawada iyo wax soo saarka baabuurta, halkaas oo walxaha khafiifka ah ee weli waara ay lagama maarmaan yihiin.
Elektrooniga & dahaarka
Iyada oo ay ugu wacan tahay sifooyinkeeda dahaarka, boehmite waxaa loo isticmaalaa qaybaha elektiroonigga ah iyo sida walxo dielectric ah. Degganaanshaheeda hoos yimaada cadaadiska korantada waxay hubisaa - wax qabad waara ee aaladaha
