Ma Chemical Properties a Lead-Free Copper

Mkuwa wopanda leadali ndi kuthekera kwakukulu, sangalowe m'malo mwa haidrojeni m'madzi, ndipo ali ndi kukana kwa dzimbiri mumlengalenga, madzi oyera, madzi a m'nyanja, asidi oxidizing, alkali, mchere, organic acid sing'anga ndi dothi, koma mkuwa umasungunuka mosavuta, kutentha ndi wamkulu kuposa 200 ℃, makutidwe ndi okosijeni imathandizira.Depolarization dzimbiri amapezeka mu okosijeni ndi oxidizing zidulo, ndipo mofulumira dzimbiri mu asidi nitric ndi hydrochloric acid.
Pamene mlengalenga ndi sing'anga zili ndi chloride, sulfide, gasi wokhala ndi sulfure, ndi mpweya wokhala ndi ammonia, dzimbiri zamkuwa zimachulukana, ndipo pamwamba pa zinthu zamkuwa zomwe zimakhudzidwa ndi mpweya wa mafakitale zimataya msanga, ndikupanga sulphate yamkuwa yoyambira. asidi carbonic.Copper, mtundu wa zinthu zomwe zimapangidwa nthawi zambiri zimasintha munjira zofiira zobiriwira, zofiirira, zabuluu ndi zina.Pambuyo pa zaka 10, pamwamba pa zinthu zamkuwa zidzakutidwa ndi verdigris, ndipo ma oxide amkuwa amachepetsedwa mosavuta.
Copper imatsutsana kwambiri ndi zomatira zamoyo zam'madzi, ndipo imagwiritsidwa ntchito kwambiri popanga zombo ndi zomangamanga zam'madzi.Chombocho chokutidwa ndi copper-nickel alloy chingawonjezere liwiro la sitimayo ndikuchepetsa kuwononga mafuta.Mkuwa ndi wochezeka ndi chilengedwe.Mabakiteriya osiyanasiyana sangathe kukhala pamwamba pa zinthu zamkuwa.Zinthu zambiri zamkuwa zamkuwa ndizofunikira kwambiri kuti zitsatire kukula kwa anthu ndi zomera.Choncho, mkuwa wopanda mtovu umagwiritsidwa ntchito kwambiri pantchito yomanga ndipo umagwiritsidwa ntchito popereka madzi akumwa.M'mapaipi otumizira, mwachiwonekere ndi abwino kuposa zida zina zamsewu.
