ʻO Manganese Dioxide he pauka ʻeleʻele me ka mānoanoa o 5.026g/cm3 a me kahi helu heheʻe o 390°C.ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka waikawa nitric.Hoʻokuʻu ʻia ka oxygen i ka H2SO4 wela, a hoʻokuʻu ʻia ka chlorine i ka HCL e hana i ka manganous chloride.Hoʻopili ʻo ia me ka alkali a me nā mea ʻokiʻoki.Eutectic, hoʻokuʻu carbon dioxide, hoʻohua i ka KMnO4, decompose i manganese trioxide a me ka oxygen ma 535 ° C, he oxidant ikaika.
Manganese Dioxidehe nui ka hoʻohana ʻana, e pili ana i nā ʻoihana e like me ka lāʻau lapaʻau (potassium permanganate), pale aupuni, kamaʻilio, ʻenehana uila, paʻi ʻana a me ke kala, pāʻani, hana kopa, wili, hoʻomaʻemaʻe wai, mahiʻai, a hoʻohana ʻia ma ke ʻano he disinfectant, oxidant, catalyst. , etc. Hoʻohana ʻia ka manganese dioxide e like me MNO2 ma ke ʻano he puaʻa kala no ke kala ʻana o ka ʻili o nā seramika a me nā pōhaku lepo a me nā tile, e like me ka ʻeleʻele, ʻōmaʻomaʻo, poni, ʻeleʻele a me nā waihoʻoluʻu nani ʻē aʻe, i ʻālohilohi a paʻa ke kala.Hoʻohana pū ʻia ka manganese dioxide ma ke ʻano he depolarizer no nā pā maloʻo, ma ke ʻano he deferrous agent no nā metala manganese, nā mea hoʻoheheʻe kūikawā, nā hoʻolei ferromanganese, nā masks kinoea, a me nā mea uila, a hoʻohana ʻia hoʻi i ka lāʻau e hoʻonui i ka viscosity.
ʻO ka hui R&D o UrbanMines Tech.Co., Ltd. i hoʻokaʻawale i nā hihia noi no ka ʻoihana e pili ana i nā huahana, manganese dioxide kūikawā no ka ʻōlelo a nā mea kūʻai aku.
(1) Electrolytic Manganese Dioxide, MnO2≥91.0% .
Electrolytic Manganese Dioxidehe depolarizer maikaʻi loa ia no nā pā.Ke hoʻohālikelikeʻia me nā pila maloʻo i hanaʻia e ka manganese dioxide hoʻokuʻu maoli, loaʻa iā ia nāʻano o ka mana hoʻokuʻu nui, ka hana ikaika, ka liʻiliʻi, a me ke ola lōʻihi.Hoʻohui ʻia me 20-30% EMD Ke hoʻohālikelike ʻia me nā pā maloʻo i hana ʻia me ka MnO2 maoli, hiki i ka hopena maloʻo ke hoʻonui i ko lākou mana hoʻokuʻu e 50-100%.ʻO ka hoʻohui ʻana i ka 50-70% EMD i kahi pākaukau zinc chloride kiʻekiʻe e hiki ke hoʻonui i kona mana hoʻokuʻu ma 2-3 mau manawa.Hiki ke hoʻonui i ko lākou mana hoʻokuʻu i nā manawa 5-7 i nā ʻeke alkaline-manganese i hana ʻia me EMD.No laila, ua lilo ka electrolytic manganese dioxide i mea waiwai nui no ka ʻoihana pākaukau.
Ma waho aʻe o ka lilo ʻana i mea waiwai nui o nā pila, hoʻohana nui ʻia ka manganese dioxide electrolytic i loko o ke kūlana kino i nā ʻano ʻē aʻe, e like me: ma ke ʻano he oxidant i ke kaʻina hana o nā kemika maikaʻi, a ma ke ʻano he mea maka no ka hana ʻana i ka manganese- zinc ferrite palupalu māneʻe mea .Loaʻa i ka electrolytic manganese dioxide ka catalytic ikaika, oxidation-reduction, hoʻololi ion a me nā hiki adsorption.Ma hope o ka hana ʻana a me ka hoʻoheheʻe ʻana, lilo ia i ʻano mea kānana hoʻomaʻemaʻe wai maikaʻi me ka hana piha.Hoʻohālikelike ʻia me ka carbon activated maʻamau, zeolite a me nā mea kānana hoʻomaʻemaʻe wai ʻē aʻe, ʻoi aku ka ikaika o ka decolorize a wehe i nā metala!
(2) Lithium Manganese Oxide Grade Electrolytic Manganese Dioxide, MnO2≥92.0% .
Lithium Manganese Oxide Grade Electrolytic Manganese DioxideHoʻohana nui ʻia i nā ʻeke lithium manganese mana.Hōʻike ʻia ka pā uila Lithium manganese dioxide e kona ikehu kikoʻī (a hiki i 250 Wh/kg a me 500 Wh/L), A me ke kūpaʻa hana uila kiʻekiʻe a me ka palekana i ka hoʻohana.He kūpono ia no ka hoʻokuʻu ʻana i ka wā lōʻihi ma kahi ākea o kēia manawa o 1mA/cm~2 ma kahi mahana o ka liʻiliʻi o 20 ° C a me 70 ° C.He 3 volts ko ka pākaukau.Hāʻawi ka hui ʻenehana ʻo British Ventour (Venture) i nā mea hoʻohana i ʻekolu mau ʻano hana o nā pā lithium: pihi lithium batteries, cylindrical lithium batteries, a me cylindrical aluminum lithium batteries i hoʻopaʻa ʻia me nā polymers.Ke hoʻomohala nei nā mea uila uila uila ma ke ʻano o ka miniaturization a me ke kaumaha māmā, e koi ana i nā pihi e hāʻawi i ka ikehu no lākou e loaʻa i kēia mau pono: ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka ikehu kikoʻī kiʻekiʻe, ke ola lōʻihi o ka lawelawe, mālama ʻole ʻia, a me ka pollution. -noa.
(3) Hoʻoulu Manganese Dioxide Powder, MnO2≥75.% .
Ho'ā 'ia Manganese Dioxide(ʻeleʻele ka pauka) i hana ʻia mai ka manganese dioxide kūlohelohe kiʻekiʻe ma o ke ʻano o nā kaʻina hana e like me ka hōʻemi, disproportionation, a me ke kaupaona ʻana.He hui maoli ia o ka manganese dioxide a me ka manganese dioxide.ʻO ka hui pū ʻana he mau pōmaikaʻi kiʻekiʻe e like me ka γ-type crystal structure, kahi ākea ākea nui, ka hana hoʻoheheʻe wai maikaʻi, a me ka hana hoʻokuʻu.ʻO kēia ʻano huahana he maikaʻi koʻikoʻi ka hoʻokuʻu mau ʻana a me ka hana hoʻokuʻu manawaleʻa, a hoʻohana nui ʻia i ka hana ʻana i nā pahu maloʻo zinc-manganese kiʻekiʻe.Hiki i kēia huahana ke hoʻololi i ka manganese dioxide electrolytic i ka wā e hoʻohana ʻia ai i loko o nā ʻano ʻano pilahi kiʻekiʻe-chloride zinc (P), a hiki ke hoʻololi piha i ka manganese dioxide electrolytic ke hoʻohana ʻia i loko o nā ʻano pāʻani ammonium chloride (C).He hopena maikaʻi ke kumu kūʻai.
Eia nā laʻana o nā hoʻohana kikoʻī:
a .ʻO ke aniani kala seramika: nā mea hoʻohui i ka ʻeleʻele ʻeleʻele, ka ʻulaʻula manganese a me ke aniani ʻeleʻele;
b .ʻO ka noi i loko o ka penikala ink ceramic ka mea kūpono no ka hoʻohana ʻana i ka mea hoʻonaninani ʻeleʻele kiʻekiʻe no ka glaze;ʻoi aku ka kiʻekiʻe o ka saturation kala ma mua o ka manganese oxide maʻamau, a ʻo ka calcining synthesis wela ma kahi o 20 degere haʻahaʻa ma mua o ka electrolytic manganese dioxide.
c .Nā mea waena lāʻau lapaʻau, oxidants, catalysts;
d .Decolorizer no ka ʻoihana aniani;
(4) Manganese Dioxide Maʻemaʻe Kiʻekiʻe, MnO2 96%-99%.
Ma hope o nā makahiki o ka hana nui, ua holomua ka huiʻO Manganese Dioxide Maʻemaʻe Kiʻekiʻeme ka maʻiʻo o 96%-99% .ʻO ka huahana i hoʻololi ʻia he mau hiʻohiʻona o ka oxidation ikaika a me ka hoʻokuʻu ikaika ʻana, a ʻo ke kumukūʻai he mea maikaʻi loa ke hoʻohālikelike ʻia me ka electrolytic manganese dioxide.ʻO Manganese dioxide he pauka amorphous ʻeleʻele a i ʻole ʻeleʻele orthorhombic ʻeleʻele.He oxide paʻa ia o ka manganese.ʻIke pinepine ia i nā nodule pyrolusite a me manganese.ʻO ke kumu nui o ka manganese dioxide ʻo ia ka hana ʻana i nā pihi maloʻo, e like me nā ʻeke kalapona-zinc a me nā pā alkaline.Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he catalyst i nā hopena kemika, a i ʻole ma ke ʻano he mea oxidizing ikaika i loko o nā hopena acidic.ʻO Manganese dioxide he mea hoʻoheheʻe ʻole amphoteric (non-salt-forming oxide), he paʻa paʻa ʻeleʻele paʻa loa i ka lumi wela a hiki ke hoʻohana ʻia ma ke ʻano he depolarizer no nā pila maloʻo.He oxidant ikaika nō hoʻi ia, ʻaʻole ia e wela iā ia iho, akā kākoʻo i ka puhi ʻana, no laila ʻaʻole pono e hui pū ʻia me nā mea puhi.
Eia nā laʻana o nā hoʻohana kikoʻī:
a .Hoʻohana nui ʻia ia e like me ka depolarizer i loko o nā pila maloʻo.He mea maikai decolorizing ma ka oihana aniani.Hiki iā ia ke oxidize i nā paʻakai hao haʻahaʻa i nā paʻakai hao kiʻekiʻe, a e hoʻohuli i ke kala uliuli-'ōmaʻomaʻo o ke aniani i melemele nāwaliwali.
b.Hoʻohana ʻia ia e hana i nā mea magnetic manganese-zinc ferrite i loko o ka ʻoihana uila, ma ke ʻano he mea maka no nā ferro-manganese alloys i ka ʻoihana hana kila, a ma ke ʻano he mea hoʻomehana i ka ʻoihana hoʻoheheʻe.Hoʻohana ʻia ma ke ʻano he absorbent no ka carbon monoxide i nā masks kinoea.
c .I loko o ka ʻoihana kemika, hoʻohana ʻia ʻo ia ma ke ʻano he oxidizing agent (e like me ka purpurin synthesis), he catalyst no ka organik synthesis, a he desiccant no nā pena a me nā inika.
d .Hoʻohana ʻia ma ke ʻano he kōkua puhi ahi i ka ʻoihana pāʻani, ma ke ʻano he mea maka no nā seramika a me nā aniani enamel a me nā paʻakai manganese.
e .Hoʻohana ʻia i ka pyrotechnics, ka hoʻomaʻemaʻe wai a me ka wehe ʻana i ka hao, ka lāʻau lapaʻau, ka mea momona a me ka paʻi lole a me ke kala, etc.
