Chifukwa mdima siliva

Chifukwa mdima siliva? Nkhani nkhawa eni onse zodzikongoletsera mtengo anapangidwa kuchokera zitsulo izi.

Silver - wolemekezeka zitsulo ndi reactivity mokwanira otsika kuchitapo kanthu a oxidant ambiri - madzi ndi mpweya. Komabe, pamaso pawo Komano, mosavuta amachitira ndi chinthu china - ndi divalent sulfure. Zimene chifukwa umabala Ag2S - sulfide siliva, amene ali chinthu wakuda. M'mikhalidwe wabwinobwino, pa zodzikongoletsera zopangidwa sulfide siliva aumbike pang'onopang'ono. Choyamba, yamba zokongoletsa yokutidwa sadzachitanso amaonekera imvi Chifunga, ndiye amakhala pafupifupi wakuda patina.

Kuti timvetse chifukwa siliva mdima, muyenera kudziwa kuti ndi chifukwa chakuti umatanthauza monga mchitidwe mankhwala, angathe zimavuta ndi zachilengedwe. Mdani waukulu wolemekezeka siliva mtundu ndi sulfure katundu H2S (sulfide wa hydrogen), imbaenda makutidwe ndi okosijeni ake. Mmene youma sulfide wa hydrogen sayambitsa anachita zimenezi. Kuti tichite zimenezi, kukhalapo kwa chinyezi. Mlingo anachita angathe kuwonjezera kutentha pa zimene kuenjezera sulfide wa hydrogen dzimbiri akhoza inapita patsogolo kwambiri. Mwachitsanzo, ngati kutentha limatuluka kuchokera madigiri 20 kuti 40, mlingo yomweyo ya ukuwonjezeka dzimbiri kwa nthawi 25

Mu chikhalidwe mwaulere zinthu pano monga ozoni, amoniya, mankhwala enaake a hydrogen, sulfide wa hydrogen, woipa sulfure , ndi ufulu sulfure. Malinga ndi ndende ya zinthu zimenezi ndi chinyezi siliva dzimbiri akhoza nakweza kapena attenuated. The makutidwe ndi okosijeni chifukwa Ag2S zitsulo pa nthawi kumawonjezera ❖ kuyanika wosanjikiza wa nkhani.

Ndiye n'chifukwa mdima siliva zimaonekeratu. Koma popanda anati sulphide wa hydrogen mulinso mpweya ndi madzi. Ichi ndi chinthu chotsatira. Pa zili mkulu mu madzi zachilengedwe ntchito pawiri ichi monga mankhwala ndi - sulfides (sulfide wa hydrogen) madzi.

Ndiwo mpweya sulfide wa hydrogen mu mlengalenga - mabizinezi mafakitale yotulutsa CHIKWANGWANI yokumba, ayenga mafuta ndi zomera coke, komanso pafupifupi onse magalimoto. Pankhaniyi, zikuoneka ngati mankhwala a kuwonongeka kwa organic (zinyalala).

Kuchokera pa zimene darkens siliva zinthu zabwinobwino, ngati inu sizimathandiza kupewa izo kuchokera kukhudzana ndi madzi? Kupanga sulfide filimu pa miyala yamtengo wapatali ndi pokhudzana kapena chabe pafupi kupeza zipangizo organic Mwachitsanzo, mankhwala mphira, mapulasitiki.

Musaiwale kuti thupi lathu lokha amatha yopangira sulfure. Lifikira ochokera kunja kwa thupi ndi chakudya kapena mankhwala (streptotsidom, sulphadimezin Sulfazin, mafuta zosiyanasiyana ndi kukonzekera zina. Mu njira ya kagayidwe, sulfure akhoza kusanduka H2S ndi kuchokera pamwamba khungu pamodzi ndi thukuta, amene ali kukhudzana ndi mphete, pakhosi zosonyeza ndi wachibale zokongoletsa wathu.

Atafufuza anyamarwa a siliva, tikutha kumvetsa tsopano osati kokha chifukwa mdima siliva, koma kuzindikira kuti kupewa browning ngati kuli kovuta. Chifukwa ife sitingakhoze kukhala moyo popanda mpweya, madzi, ndipo sangathe kusintha zimene thupi lake.

Koma si zifukwa mdima siliva. Popeza ichi zodzikongoletsera zitsulo si ntchito mu mawonekedwe woyera, koma kasakaniza wazitsulo ndi nthawi zambili zili mkuwa. Mu mlengalenga ndi oxidized kuti Cu2O, kukhala azioneka utoto. Ngati mankhwala si ataphimbidwa ndi wosanjikiza kuteteza Mwachitsanzo, Analandira kapena palladium, iwo amayembekedzera kuwononga. Winayo anapatsidwa.

Zimene mungachite kuti tidzakhale ndi moyo wa siliva, ndi kukhala kukongola choyambirira zodzikongoletsera kuchokera izo? Muyenera kuonetsetsa kuti mankhwala si ukagwira sanali pa malo achinyezi. Pambuyo atavala iwo ayenera kutsukidwa ku secretions khungu. Kumathandiza ndi nthawi kukonza kutenga kukongoletsa masitolo zodzikongoletsera kapena kuyeretsa iwo pogwiritsa ntchito madzi sopo ndi Kuwonjezera wa ammonia.
