Konupora waikura: Āhuatanga, takanga, tono

Kei te maha Konupora waikura tuku ki te magnesia tinana atu noa ranei waikura konupora. Ko tēnei rauemi he ono tekau, me te pai paura ma tioata. I roto i te natura, puta te waikura konupora rite te periclase kohuke. Ko te ahumahi kai ko te taonga e mohiotia ana ko te tāpiri kai i raro i waehere E530.

Āhuatanga o te konupora ōkai

Tātai Chemical o te taonga: MgO. Tenei pūhui e tata kahore kakara i roto i te haukini me te he ngāwari wairewa i roto i te wai i te waikawa, tona memehatanga i 30 ° C, ko te 0,0086 anake karamu / 100 ml, me he waipiro, me e kore e tareka te reira. papatipu titiwha o MgO - 40,3044 g / mol. I 20 ° C, me tona kiato ko 3.58 g / cm³, kohua pāmahana - 3600 ° C, rewa - 2852 ° C. Ko matū waikura konupora Melkokristallichesky kaha rawa. Ko reira, e nehenehe o te ngongo hauhā ki te hanga i te pākawa waro hāngai:

• MgO + CO ₂ = MgCO _3;

ahakoa āta, engari tauhohe tonu ki te wai, hanga rewakore turanga ngoikore :

• H ₂ E + MgO = Mg (OH) _2;

Kei te ähua ki te waikawa:

• 2HCl + MgO = MgCl ₂ + H ₂ e

Te waikura konupora calcined mona tona tauhohenga. kia hoki kia tapiritia reira e tenei gigroskopechen paura.

Te faaineineraa o te waikura konupora

I roto i te ahumahi, i rite tenei pūhui tino na roto i te pupuhi. whakamahia te rauemi raw kohuke pērā i dolomite (MgCO3.CaCO3) magnesia (MgCO3) ranei. I tua atu, kawea magnesia te i roto i te whakamahi i te bishofit calcination (MgCl ₂ x 6H ₂ E) i roto i te kohu wai, calcining Mg (OH) 2 me ētahi atu iu ki pāmahana Mg pūhui. I raro i ngā āhuatanga taiwhanga, kia rite MgO i te tauhohenga o ona wāhanga wāhanga:

• 2Mg + e ₂ = 2MgO;

ranei i te whāwehe waiariki o etahi tai waihā ranei:

• MgCO ₃ = MgO + CO _2.

Tei runga i te tikanga hanga o te waikura konupora he tikanga ki te wehewehe e rua ngā momo matua o pūhui: marama me te magnesia taimaha. Ko te tuatahi ko te paura te huitahi, i te mea ngāwari nui ki te tomo ki roto ki te tauhohe ngā ki waikawa memeha, ai tai Mg e hanga e. Kei te tuarua o te tioata nui o periclase tūturu waihanga ranei me resistance wai taiea, me te he atu e mangere.

waikura konupora

I roto i te ahumahi, kei te whakamahia tenei pūhui mō te hokohoko i sima, whakangutungutu, rite filler i rapa, me te mo te maimoatanga hinu kohuke. whakamahia waikura konupora Ultralight te rite te tino pai auaha, i purea mata. I roto i ngā, kua whakamahia te reira i roto i te ahumahi te hikohiko. I tua atu, kei te whānui e whakamahia ana magnesia i rongoā. whakamahia hea MgO te i roto i te ofatiraa o te taumata kawatanga pekitīlia puta tika ki te taikaha o te waikawa pūhaumāota. tango hoki Konupora waikura mō te neutralizing matū kaha aitua mau i roto i te kopu. I roto i te ahumahi kai whakamahia MgO te rite te tāpiri kai (E530) waehere, e ārai clumping me Shade. Kei te whakamahia hoki Magnesia i roto i taka porepore. Here, tono te paura kei ki nga ringa o nga kaitäkaro ki te whakapā atu ki te taputapu mahi ko atu pono. Tāpiri i te konupora waikura ko te reflector tino. He rite ki te kotahitanga te whakarea whakaata o te taonga i roto i te ropu spectral whānui, me te reira kia pai te whakamahi i te reira rite te tohutoro ma.
