Za mkuwa

Mkuwandi imodzi mwazitsulo zakale kwambiri zomwe anthu adapeza ndikuzigwiritsa ntchito, zofiirira-zofiira, mphamvu yokoka yeniyeni 8.89, malo osungunuka 1083.4 ℃.Mkuwa ndi ma aloyi ake amagwiritsidwa ntchito kwambiri chifukwa cha madutsidwe awo abwino amagetsi ndi matenthedwe matenthedwe, kukana dzimbiri mwamphamvu, kukonza kosavuta, kulimba kwamphamvu komanso kutopa, chachiwiri chitsulo ndi aluminiyamu pakugwiritsa ntchito zitsulo, ndipo zakhala zofunikira kwambiri komanso njira. zipangizo mu chuma cha dziko ndi moyo wa anthu, ntchito chitetezo dziko komanso minda yapamwamba chatekinoloje.Amagwiritsidwa ntchito kwambiri m'makampani amagetsi, mafakitale amakina, makampani opanga mankhwala, makampani oteteza dziko ndi madipatimenti ena.Copper fine powder ndi chinthu chomwe chimapangidwa ndi miyala yaiwisi yokhala ndi mkuwa yotsika kwambiri yomwe yafika pamlingo wina wake kudzera munjira yopindulitsa ndipo imatha kuperekedwa mwachindunji kwa osungunula kuti asungunuke mkuwa.

Mkuwa ndi chitsulo cholemera, malo ake osungunuka ndi madigiri 1083 Celsius, malo otentha ndi madigiri 2310, mkuwa weniweni ndi wofiirira-wofiira.Chitsulo chamkuwa chimakhala ndi mphamvu yabwino yamagetsi ndi matenthedwe, ndipo mphamvu yake yamagetsi imakhala yachiwiri pazitsulo zonse, yachiwiri kwa siliva.Kutentha kwake kumakhala kwachitatu, kwachiwiri kwa siliva ndi golidi.Mkuwa woyengedwa ndi wonyezimira kwambiri, kukula kwake ngati dontho la madzi, ukhoza kukokedwa mu ulusi wotalika mamita 2,000, kapena kukulungidwa mu nsalu yooneka bwino kwambiri yokulirapo kuposa pamwamba pa bedi.

 

"Zovala zamkuwa zoyera za phosphor" ziyenera kutanthauza "mkuwa wa phosphor wokhala ndi zokutira zoyera pamwamba"."Zoyera zoyera" ndi "phosphor mkuwa" ziyenera kumveka mosiyana.

White plating -- Maonekedwe a mtundu wa zokutira ndi woyera.Zopangira plating ndizosiyana kapena filimu ya passivation ndi yosiyana, mawonekedwe amtundu wa zokutira nawonso amasiyana.Phosphor mkuwa wa zida zamagetsi ndi zoyera popanda passivation.

 

Phosphorus mkuwa - mkuwa wokhala ndi phosphorous.Mkuwa wa phosphorus ndi wosavuta kugulitsa ndipo umakhala wosalala bwino, ndipo umagwiritsidwa ntchito kwambiri pazida zamagetsi.

 

Mkuwa wofiirandi mkuwa.Dzinali limachokera ku mtundu wake wofiirira.Onani mkuwa pazinthu zosiyanasiyana.

Mkuwa wofiyira ndi mkuwa weniweni wa mafakitale, malo ake osungunuka ndi 1083 ° C, palibe kusintha kwa isomerism, ndipo kachulukidwe kake ndi 8.9, kasanu kuposa magnesium.Pafupifupi 15% yolemera kuposa chitsulo wamba.Wawuka wofiira, wofiirira pambuyo pa mapangidwe a oxide filimu pamwamba, choncho amatchedwa mkuwa.Ndi mkuwa wokhala ndi mpweya wochuluka, choncho umatchedwanso mkuwa wokhala ndi mpweya.

Mkuwa wofiyira umatchulidwa chifukwa cha mtundu wake wofiira.Sikuti ndi mkuwa wangwiro, ndipo nthawi zina kagawo kakang'ono ka deoxidation kapena zinthu zina zimawonjezedwa kuti ziwongolere bwino zakuthupi ndi magwiridwe antchito, motero zimatchulidwanso ngati aloyi yamkuwa.Zida zaku China zopangira mkuwa zitha kugawidwa m'magulu anayi molingana ndi kapangidwe kake: mkuwa wamba (T1, T2, T3, T4), mkuwa wopanda okosijeni (TU1, TU2 ndi kuyera kwambiri, mkuwa wopanda okosijeni), mkuwa wopanda oxygen (TUP). , TUMn), ndi mkuwa wapadera (mkuwa wa arsenic, mkuwa wa tellurium, mkuwa wa siliva) wokhala ndi zinthu zochepa zowonjezera.Mphamvu yamagetsi ndi matenthedwe amkuwa ndi yachiwiri kwa siliva, ndipo imagwiritsidwa ntchito kwambiri popanga zida zoyendetsera ndi zotentha.Mkuwa m'mlengalenga, m'madzi a m'nyanja ndi zina zopanda oxidizing zidulo (hydrochloric acid, dilute sulfuric acid), alkali, mchere wa mchere ndi mitundu yosiyanasiyana ya organic acid (acetic acid, citric acid), imakhala ndi kukana kwa dzimbiri, komwe kumagwiritsidwa ntchito pamakampani opanga mankhwala.Kuphatikiza apo, mkuwa umakhala ndi weldability wabwino ndipo umatha kupangidwa kukhala zinthu zingapo zomalizidwa pang'ono ndi zinthu zomalizidwa ndi kuzizira komanso kutentha kwa thermoplastic.M'zaka za m'ma 1970, kupanga mkuwa wofiyira kunaposa kupanga ma alloys ena onse amkuwa.
