Mun na MgO jogo nafa ka bon kosɛbɛ tasumabɔlanw dilanni na?

Kuran tasumabɔlan dilannikɛlaw fɛ, manje mugu (manjesiyɔmu ɔkisidi mugu, MgO) ye kuran tasumabɔlan "dusukun" ye. A jogo bɛ a jira k’a ɲɛsin sofalan lakanani, a baarakɛcogo ani a baara waati ma.

Manje mugu ye mun ye?

"Magnesium oxide powder" tɔgɔ ɲuman ye MgO ye, o ye ionique compound ye min bɛ kɛ ni magnesium ni oxygen ye. O ye mugu ɲuman finman ye, kasa tɛ a la, wa a da man di.

Sɛnɛfɛnw baara fanba la, i n’a fɔ kuran tasumamuguw, an bɛ min wele ko «manje mugu» tiɲɛ na, o ye «manjesiyɔmu ɔkisidi mugu» (MgO) ye, o ye seramiki fɛn sabatilen ye, min tɛ - tasuma, a ni manje mugu nɛgɛma tasuma bɛ se ka tasuma bɔ, o tɛ kelen ye kosɛbɛ.

Mun na a nafa ka bon ka baara kɛ ni manje ɔkisidi mugu ye min ka ɲi-sumaya fɛnw na?

O bɛ bɔ a ka fɛn koloma naani na, minnu bɛ funtenifɛnw baarakɛcogo, u lakanani ani u si hakɛ dantigɛ k’a ɲɛsin u ma:

1. Insulation ɲumanba

Magnesium oxide is an excellent insulator with an extremely high resistivity (>1013 Ω·cm ye so funteni na). A bɛ tasuma-fanga-minɛn fangama (resistance-wire) bɔ nɛgɛ lamini na ni dannaya ye, ka bɔgɔbɔli walima kurukuruniw bali ani ka baarakɛlaw lakana. O de y’a ka baara jɔnjɔn ye.

2. Sumaya-sɔgɔsɔgɔninjɛ ɲumanba

Manzeyɔmu ɔkisidi ka funteni-taamacogo (30-40 W/(m·K) ɲɔgɔn) ka bon kosɛbɛ ni fiɲɛ ta ye. A bɛ funteni caman- funteni min bɛ sɔrɔ tasumabɔlan fɛ, o bɛ taa nɛgɛdaga la cogo ɲuman na ani cogo kelen na, ka sɔrɔ ka taa fɛn sumalen na. O tɛ dan funteni nafa dɔrɔn ma, nka a bɛ funteni dalajɛli bali fana tasumabɔlan kɔnɔ, o bɛ se ka kɛ sababu ye ka yɔrɔ dɔw sumaya kojugu ani ka a jeni, o la, a ka ɲɛnamaya bɛ janya. 3. Kimiki sabatili ni funteni caman kɛlɛli

3. ɔkisizɛni manje min sɔgɔlen don , o wulicogo bɛ se degere 2800 ma .

A bɛ sabati kosɛbɛ funtenifɛnw ka baarakɛta funteni hakɛ danmadɔw la (a bɛ se degere kɛmɛ caman ma fo ka se degere ba caman ma). A tɛ toli, ka wuli, walima ka kɛ kemikɛli ye ni tasuma-fanga-minɛn walima nɛgɛ-tubabu-kɔnɔna ye min bɛ a kɔnɔ, o bɛ a to dannaya bɛ se ka da a kan waati jan kɔnɔ.

4. Masina fanga ka bon ani Packing Density

Sumayafɛnw dilanni senfɛ, "tube shrinking" kɛcogo dɔ bɛ Kɛ, nɛgɛ tubabu bɛ Dòn min na ni degunba ye walasa ka manje ɔkisidi mugu min bɛ a kɔnɔ, o bɛ Dòn ɲɔgɔn na. Manje ɔkisidi mugu min ka ɲi kosɛbɛ, ni a fɛnɲɛnamafagalanw hakɛ tilatilali tigitigi bɛ se ka o degun in muɲu k’a sɔrɔ a ma tiɲɛ. A sɔgɔlen kɔfɛ, a bɛ se ka pakew hakɛ caya kosɛbɛ, ka kɔnɔna yɔrɔw bɔ yen, ka insulasi ni funteni minɛcogo caman sabati, ani ka baarakɛcogo tiɲɛni bali ka da yɛrɛyɛrɛ kan.

Ka da o jogo ninnu kan, manje ɔkisidi mugu bɛ kɛ fɔlɔ nin na:

Sumayafɛnw: Nin ye a kɛyɔrɔ ye min ka bon kosɛbɛ. A bɛ kɛ tubabufura suguya caman na (sumaya tubabukan), strip sofaw, plati funtenilanw, ani baara wɛrɛw la. A ka teli ka sɔrɔ kuran-minɛnw na, forow la, yɔrɔ-suma-minɛnw na, iziniw ka bɔgɔdagaw la, ani fɛn wɛrɛw.

Sugu la, manje mugu min bɛ se ka kɛ standard/mid{0}}range grade, MgO saniyalen bɛ 98% fo 99,3% ɲɔgɔn na, a bɛ waso ni insulasi ni funteni minɛcogo ɲuman ye, ani ji minɛcogo min bɛ kɔrɔsi ka ɲɛ. A bɛ kuran tasuma-fanga-minɛn fanba ka ɲininiw dafa, o min b’a to a bɛ kɛ sugandili ye min ka di du kɔnɔ minɛnw ye minnu bɛ kɛ tuma bɛɛ i n’a fɔ kuran jisumalanw, forow, mikrowɛnw, tiga tobilikɛminɛnw, ani jisumalanw.

Cogo di ka kan ka kɛMgOka sugandi ka da tasuma-fanga-tubabu cɛmancɛ ni tasuma-fanga-minɛn kan?

Ni aw bɛ manje mugu sugandi, aw bɛ a kɛcogo, a kɛcogo, a cɛmancɛ ani a janya fɔ.

A.Ni aw bɛ tubabufura sumaya min cɛmancɛ ye milimɛtɛrɛ 8 ye walima ka tɛmɛ o kan, aw bɛ manje mugu 40-325 mesh kɛ ka a kɛ funteni cɛmancɛ- ni funteni dɔgɔman na, i n’a fɔ tiga tobilikɛminɛnw sumayafɛnw na.

Walasa ka tubabufura sumaya ni a cɛmancɛ ye milimɛtɛrɛ 7-8 ye, aw bɛ manje mugu 50-325 mesh kɛ ka a kɛ funteni cɛmancɛ ni funteni caman na, i n’a fɔ nɛgɛw ni dagaw kɔnɔ.

Walasa ka tubabufura sumaya ni a cɛmancɛ ye milimɛtɛrɛ 6,5 ye walima a dɔgɔyalenba, aw bɛ manje mugu 60-325 mesh kɛ ka a kɛ funteni caman na, i n’a fɔ forow ni fiɲɛbɔlanw na.
