Magnalium hmoov

Magnalium yog aluminium alloy nrog 50% magnesium thiab 50% txhuas.

Cov khoom

Alloys nrog me me ntawm magnesium (kwv yees li 5%) muaj zog ntau dua, muaj zog corrosion kuj, thiab qis dua qhov ntom ntom dua li cov ntshiab txhuas. Xws li cov alloys kuj ua haujlwm tau zoo dua thiab yooj yim dua rau vuam dua li cov ntshiab txhuas. Cov alloys uas muaj cov magnesium ntau (kwv yees li 50%) yog nkig thiab muaj kev cuam tshuam rau corrosion ntau dua li txhuas.

Siv

Txawm hais tias lawv feem ntau kim dua li txhuas, lub zog siab, thiab ntau dua kev ua haujlwm ntawm cov khoom siv magnes nrog lawv siv hauv cov dav hlau thiab tsheb. Nws kuj yog siv los ua cov kab sib npaug thiab lwm yam khoom siv lub teeb.

Pyrotechnics

Alloys; uas feem ntau tsis muaj tseeb alloys tab sis intermetallic tebchaw; nrog txog 50% magnesium yog nkig thiab corrode yooj yim, uas ua rau lawv tsis haum rau feem ntau engineering siv.

Cov tebchaw no yog flammable thaum hmoov, yog resistant rau corrosion dua li cov magnesium ntshiab, thiab feem ntau yog reactive dua li ntshiab txhuas; lawv tau siv nyob rau hauv pyrotechnics raws li ib tug hlau roj rau cov xim xim, los tsim sparks nyob rau hauv ib co glitter thiab streamer hnub qub, thiab raws li ib tug zoo sib xws hloov rau cais magnesium thiab txhuas hmoov nyob rau hauv crackling microstars (daj qe). Magnalium hmoov kuj kub hnyiab nrog lub suab tawg yog tias hlawv los ntawm nws tus kheej.

Nws yog me ntsis reactive dua magnesium nyob rau hauv feem ntau, qhia tsis muaj cov tshuaj tiv thaiv nrog sulfur nyob rau hauv particular, tab sis yog ze li ntawm reactive li magnesium nrog antimony trisulfide (ua cov tshuaj lom thiab flammable Hydrogen sulfide gas) thiab ntau txaus ntshai reactive nrog nitrates, maj mam reacting rau. tsim cov roj ammonia qhov twg magnesium tsuas yog ua rau maj mam tsim cov khoom inert.

Qee zaum qhov feem ntau ceev-reacting magnesium tivthaiv ntawm magnalium ua hauj lwm kom qeeb cov tshuaj tiv thaiv vim nws cov reactivity ntau dua nyob rau hauv ib tug muaj pes tsawg leeg. Qhov no tshwm sim hauv zaj qe, qhov twg qeeb oxidation ntawm magnesium los ntawm Lead tetraoxide (Pb₃O₄) tso cai rau lub sij hawm tsim cov Lead monoxide (PbO) roj los tsim kom tsis muaj kev cuam tshuam nrog cov txhuas feem, yog li thaum cov magnesium yog thaum kawg noj cov tshuaj tiv thaiv txhuas tshwm sim sai txaus los tsim kev tawg. Yog tias muaj magnesium ntau heev nyob rau hauv cov hlau (los yog ntxiv rau qhov sib tov), ​​nws yuav hlawv tsis tu ncua tab sis tsis tsim cov nyhuv xav tau. Ib yam li magnesium me me yuav tiv thaiv kom txaus PbO vapor los ntawm lub tsev kom hnov ​​​​mob sai thiab cov txhuas yuav tsuas hlawv.

Lub ntsiab lus: Danger!

- Cov lus ceeb toom xwm txheej;

- H228: Flammable khoom

- H260: Nyob rau hauv kev sib cuag nrog dej, hluav taws kub nyhiab tshwm sim uas tuaj yeem ua rau lawv tus kheej kub hnyiab.

Cov lus qhia kev nyab xeeb.

- P210: Khaws kom deb ntawm tshav kub, qhov chaw kub, qhov hluav taws kub, qhib nplaim taws thiab lwm yam khoom siv hluav taws xob. Tsis txhob haus luam yeeb.

P370 + P378: Rau hom: siv hlau hluav taws kub hmoov rau tua.

- P402+P404: Khaws rau hauv lub thawv kaw hauv qhov chaw qhuav.
