Methane (CH4)

Magawo aukadaulo

Methane ndi chinthu chachilengedwe chokhala ndi formula ya CH4 ndi kulemera kwa mamolekyulu a 16.043. Methane ndi chinthu chosavuta kwambiri chachilengedwe komanso hydrocarbon yokhala ndi mpweya wochepa kwambiri (hydrogen yambiri). Methane imafalikira kwambiri m'chilengedwe ndipo ndiye gawo lalikulu la mpweya wachilengedwe, biogas, mpweya wa pit, ndi zina zotero, zomwe zimadziwika kuti gasi. Methane ndi mpweya wopanda mtundu komanso wopanda fungo pansi pa mikhalidwe yokhazikika. Nthawi zonse, methane imakhala yokhazikika ndipo imakhala yovuta kwambiri kusungunuka m'madzi. Sichita ndi ma oxidant amphamvu monga potaziyamu permanganate, komanso sichichita ndi ma acid amphamvu kapena alkali. Koma nthawi zina, methane imakumananso ndi ma reaction enaake. Methane ndi mafuta ofunikira kwambiri. Ndi gawo lalikulu la mpweya wachilengedwe, womwe uli pafupifupi 87%. Umagwiritsidwanso ntchito ngati mafuta wamba a zotenthetsera madzi ndi zitofu za gasi poyesa kuchuluka kwa kalori. Methane ingagwiritsidwe ntchito ngati mpweya wokhazikika komanso mpweya woyezera kupanga ma alarm a gasi oyaka. Ingagwiritsidwenso ntchito ngati gwero la kaboni la maselo a dzuwa, amorphous silicon film vapor chemical deposition, komanso ngati zopangira mankhwala ndi mankhwala. Methane imagwiritsidwanso ntchito kwambiri popanga ammonia, urea ndi carbon black. Ingagwiritsidwenso ntchito popanga methanol, hydrogen, acetylene, ethylene, formaldehyde, carbon disulfide, nitromethane, hydrocyanic acid ndi 1,4-butanediol. Chloride ya methane imatha kupanga mono-, di-, trichloromethane ndi carbon tetrachloride. Sungani m'nyumba yosungiramo zinthu yozizira, yopuma mpweya. Sungani kutali ndi moto ndi magwero otentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa padera ndi ma oxidants, ndi zina zotero, ndipo sayenera kusakanikirana. Gwiritsani ntchito magetsi osaphulika komanso malo opumira mpweya. N'koletsedwa kugwiritsa ntchito zida zamakanika ndi zida zomwe zimatha kuphulika. Malo osungiramo ayenera kukhala ndi zida zochizira mwadzidzidzi. Methane ikhoza kuvulaza chilengedwe, ndipo chisamaliro chapadera chiyenera kuperekedwa ku nsomba ndi malo osungira madzi. Chisamaliro chapadera chiyeneranso kuperekedwa pa kuipitsa madzi pamwamba, nthaka, mlengalenga ndi madzi akumwa.

Ntchito:

①Monga Mafuta

Methane imagwiritsidwa ntchito ngati mafuta a uvuni, nyumba, zotenthetsera madzi, ma uvuni, magalimoto, ma turbine, ndi zinthu zina. Imayaka ndi mpweya kuti ipange moto.

②Mu Makampani Ogulitsa Mankhwala

Methane imasinthidwa kukhala mpweya wopangidwa, chisakanizo cha carbon monoxide ndi hydrogen, mwa kusintha nthunzi.

Phukusi lachizolowezi:

Ubwino:

①Kuyera kwambiri, malo atsopano;

②Wopanga satifiketi ya ISO;

③Kutumiza mwachangu;

④Zinthu zokhazikika kuchokera mkati;

⑤Njira yowunikira pa intaneti yowongolera khalidwe pa sitepe iliyonse;

⑥Kufunika kwakukulu komanso njira yosamala yogwiritsira ntchito silinda musanadzaze;
