No ke aha la pouli kala

No ke aha la pouli kālā? Ke kahe o ka mea e hopohopo nei i nā mea o ka pipiʻi Jewelry i mai kēia mea hiki ke hooheheeia.

Kala - hanohano metala me ka lawa haʻahaʻa reactivity i ka hana ana o ka loa, he pono ole oxidant - ka wai a me ka lewa. Eia naʻe, kā lākou alo ua, nae, hooholo koke reacts me kekahi waiwai - ka divalent luaipele. Ke kūpono naoh produces Ag2S - kālā sulfide, i mea heʻeleʻele waiwai. Ma lalo o maʻamau rula, ma Jewelry i ke kālā sulfide ua hana loa lohi. Mua, Ka hoʻomakaʻai uhi māhunehune perceptible oho Ohana, laila, e lilo ia i aneane eleele patina.

ke kumu o ka pouli kala, e pono e ike i ka mea mea, no ka mea, ho like me ka i ike Nine Inch hehee ai, hiki ke interacting me kona kaiapuni. I ka papa kuhikuhiE enemi aliʻi kālā kala like 'ole o ka sulfur wale mai ana H2S (hydrogen sulfide), i hiki aku ai i kona'okesaside. Ma ke aha ka maloo hydrogen sulfide aʻole i like ka naoh. E hana i kēia, i ke alo o ka ona mau. Ke naoh uku hiki ke hoʻoulu i ke ana wela i i ka hua o ka hydrogen sulfide ka popopo hiki e hōʻeleu i me ka nui loa. No ka laʻana, ina ka mehana mai ka 20 a hiki i 40 degere, ka instantaneous uku o ka popopo, piʻi pū i 25 manawa!

Ma ka lewa kuu ike 'ona e like me'okikene kolu, ammonia, hydrogen koloriside, hydrogen sulfide, sulfur dioxide i , a ua noa ka luaipele. Ke kaumaha ma muli o ka lehulehu o kēia mau waiwai, a humidity ke kālā ka popopo hiki ke listen a attenuated. Ke kūpono'okesaside Ag2S metala ma manawa maoli o ka ka penaʻana, ahu iho o ka 'atikala.

No laila, no ke aha la poeleele hoi kālā i kālaʻe. Akā, kaawale mai la hydrogen sulphide no hoi kekahi mau ea a me ka wai. 'O kēia ka mea e hiki mai ana ololi. Ma ka maʻiʻo kiʻekiʻe i loko o maoli wai ka mea, e hoʻohana i kēia hui e like me ka lāʻau lapaʻau - sulfides (hydrogen sulfide) o ka wai.

I ka papa kuhikuhiE kumu o ka hydrogen sulfide hoʻomehana honua i loko o ka lewa - hanalima hana i pakaʻimi hoʻopunipuni puluniu, aila refineries a me Coke mea kanu, e like me nā mea a pau aneane kaa. Ma keia hihia, eia kahi mea akaka me he huahana o ka decomposition o ke aloha mea (neoneo).

Mai mea darkens i ke kālā i loko o maʻamau rula, ina oe e e pale ia mai ka hui 'ana me ka wai? Hana i kekahi sulfide ho film ma luna o ka jewelery, a ma ka hui 'paha e pili kokoke ana i loaa ke aloha pono, no ka laʻana, laholio i huiʻia, Ka lula ea Ke.

Mai poina i ko kakou kino wale mea hiki ke luaipele. Ua komo mai mawaho o ke kino me kaʻai a me ka ai '(streptotsidom, sulphadimezin Sulfazin, likeʻole me ka hinu a me nā hoomakaukau, Ma ke ala o ka pūnao, hiki e hoemiia luaipele i H2S a mai o ka ili' ilikai a pau me ka hou, i mea ma ka hui 'ana me nā apo, pendants a me nā Like Me mākou nā mea hoʻonani.

Hope nana i na enemi o ke kala, ua manawa maopopo ole wale no ke aha la pouli kala, akā, i ike i ke pale aku i ka browning mea aneane hiki ole i. No ka mea, ua hiki ole ke ola me ka lewa, ka wai, a me ka mea i hiki ke hoʻololi i ka naoh o kona kino iho.

Akā, i ka i pau na kumu pouli kālā. No ka mea, i hoʻohana 'ia i kēia mea hiki ke hooheheeia Jewelry i loko o ke gula palapala, akā, wale i loko o na oka a pau, loa pinepine ka mea, aia no iloko olaila ke keleawe. Ma o ka lewa ka mea, ua oxidized ia Cu2O, e loaa he ulaula iki hue. Inā ua i uhiia i ka huina hoonui e ke aiiay ahu iho la ka, no kekahi laʻana, radium paha palladium, ka mea e mau blacken. Ka mea'ē aʻe ua i haawiia mai.

He aha e hiki ke hana, e hooloihi i ka ola o ke kala, a me ka malama i ka palapala nani o ka Jewelry mai o ia? Oe Pono e eʻoiaʻiʻo i ka huina hoonui ua ole overheated,ʻaʻole e noho ana i loko o pulu ka wahi. Ma hope o komo ia E e ua holoiʻia mai ka ili secretions. No hoi e pono i kekahi manawa no ka hoʻomaʻemaʻe e lawe mea hoʻonani i Jewelry pōʻeleʻele loa paha, e hoʻomaʻemaʻe iā lākou ma ka hoʻohana 'ana i soapy wai me ka hou o ka ammonia.
