Yako Inotungamira Boehmite Mutengesi
Luoyang Zhongchao New Material Co., Ltd. (inozonzi "ZC-TECH") iri muIndustrial Cluster Zone, Henan Province, China, inofukidza nzvimbo inodarika mahekita makumi matanhatu. Rakavambwa muna 2003, ibhizinesi rinobatanidza tsvakiridzo nebudiriro, kugadzira, nekutengesa zvinhu zvinochengetedza nharaunda netsvina{6}}yemahara. Zvigadzirwa zvayo zvikuru ialuminium based super fine flame-retardant material uye magnesium based super fine flame-retardant material, special alumina, spherical alumina, boehmite, advanced ceramics, electronic ceramics and other inorganic material.
Ipai madhizaini eforamu anoenderana nezvinodiwa zvakakosha sekuzadza zvakanyanya, utsi hushoma, uye halogen-maapplication emahara.
Nhoroondo ye Boehmite Properties
Chemical properties
Chena; ortho{{0}rhomb; a=0.286 nm, b=1.2227nm, c{3}}nm; kuoma kuri 3.5–4 Mohs; inowanikwa ne hydrothermal reaction ye hydroxide slurries pa200℃-250 degree.
Boehmite is an aluminium oxide hydroxide (-AlO(OH)) mineral, chikamu chealuminium ore bauxite. Iyo ndeye orthorhombic system uye ine dhizaini dhizaini. Muchikamu chega chega chechimiro, maion eokisijeni anorongwa mu cubic close-akarongedzerwa mumativi eoctahedron, uye maion ealuminium anowanikwa pakati peoctahedron kuti aite kaviri-layer structure. , iyo hydroxide radicals iri pamusoro peiyo yakaturikidzana dhizaini, uye machira akabatanidzwa ne hydrogen zvisungo.
Zvinhu zvemuviri
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), Equation (1 – 2). Saizvozvo, alumina refineries anowanzo gadzirirwa kunyatsogadzirisa imwe mhando ye bauxite. Kunyange zvazvo boehmitic bauxites inowanzogadziriswa nekushandisa 'tembiricha yepamusoro' yekugayiwa kwemafuta (kudzoreredza boehmite) mune dzidziso kuti boehmitic bauxite inogona kugadzirwa mune yakaderera tembiricha chirimwa pasina kana kushoma maitiro maitiro kana mazinga eboehmite aive akadzikira zvakakwana, kunyangwe iyi boehmite yemukati isina kunyungudika, ichiwedzera zvakasara kuwanda kujekeswa.

Kushandiswa kweBoehmite
Kugadzirwa kweAluminium
Boehmite inotangira muBayer process, uko inoverengerwa kugadzira alumina. Iyi alumina inobva yanyungudutswa kuburitsa simbi yealuminium. Kuchena kwe boehmite kunokanganisa zvakananga kushanda uye kunaka kwekugadzirwa kwealuminium, zvichiita kuti ive yakakosha mbishi zvinhu.
Catalysts & petrochemicals
Mukugadzirisa mashandisirwo, boehmite inoshanda sechinhu chekutsigira. Yayo yakakwirira pamusoro penzvimbo uye kugadzikana kwekupisa kunosimudzira catalyst chiitiko, kunyanya mukunatsa uye petrochemical maitiro. Izvi zvinoguma nekuita kwemakemikari kunoshanda uye kuderedzwa kwemari yekushandisa.
Ceramics & refractories
Yakakwira-hupfu hweboehmite husingachinji kutonhora hunoshandiswa mukugadzira zvidhinha zvinoramba kunyura uye zvinhu zvedongo. Zvinhu izvi zvinomira nekupisa kwakanyanya muvira, hovhoni, uye mareactor, kuve nechokwadi chekugara uye kuchengetedzeka.
Mapolymers & makompositi
Boehmite inosanganisirwa mumapolymer matrices kuti ivandudze kugadzikana kwekupisa uye simba remuchina. Ichi chishandiso chinobatsira maindasitiri senge aerospace uye kugadzira mota, uko zvinhu zvakareruka asi zvakasimba zvakakosha.
Electronics & insulation
Nekuda kweiyo insulating zvivakwa, boehmite inoshandiswa mune zvemagetsi zvikamu uye se dielectric zvinhu. Kugadzikana kwayo pasi pekunetseka kwemagetsi kunoita kuti{1}}irambe ichishanda mumidziyo.
Zvekufambisa:Zvisiri-zvinhu zvine ngozi, asi panguva yekufambisa kudzivirira hunyoro, ramba wakaoma, wakavharwa.
Kuchengeta:Chengetedza munzvimbo yakaoma uye ine mhepo, kwete mu o
