Talooyin ku saabsan sida si loo ogaado lacagtii guriga

Science ee da'da casriga ah ee horumarka farsamada uusan weli taagan, sababtoo ah maalin walba Been habab cusub oo cusub si ay u soo jiidaan faa'iido u ah Dadka oo dhan iyo dadka gaarka ah ee gaar ah, oo ay ku jiraan ma ugu nadiif ah marka la eego xidhiidhka sharciga iyo qalbi - khaa'imiintan iibiyaan lacag ah, isku sharraxdid "lacag ah" lacag-plated iyo sameeyey. Si aan si ay u noqdaan dhibanayaasha ay, waxaa lagama maarmaan ah in ay door biday in ay adeegyada takhasus, ama ugu yaraan ku gartaan si loo ogaado lacagtii guriga. Oo waxaa loo huray in our article.

First, aad u baahan tahay in la ogaado sifooyinka wax laga sameeyey haweenka iyo dahabka ragga. Silver - sharaf leh biraha isagoo guryaha conductivity kaamerada sare, gacnta wanaagsan iyo birlabta. og, waxaan ku siin karaa dhowr siyaabood oo ku saabsan sida si loo ogaado lacagtii guriga:

1. dahabka, giraan ah ee qalabka lagu cuno lacag si fudud ay qaataan gacmo diiran, iyo haddii qayb ka mid ah wax soo saarka ee lagu rusheeyey biyo kulul si dhakhso ah oo dhan waxa uu noqonayaa sida u kulul yihiin sida biyaha,
2. haddii ay wax gaaraanna in wax soo saarka ee magnet lacagtii joogo, waxay sii wadi doontaa in ay been in ay meel, sababta oo ah birta qaaliga ah magnetization ma aha hanti;
3. Habka saddexaad la xidhiidha nooca tallaabooyin xad-dhaaf ah si aan degdeg ah waa ka wanaagsan in aadan isticmaalin - sida soo horjeeda naxaasta been abuur ah, sheyga oo lacag dhab ah loo wada xodan kara.

Intaa waxaa dheer, waxaa jira dhowr siyaabood oo ku saabsan sida si loo ogaado lacagtii guriga, sida:

1. xoqin lacagtii gacmahooda ku - haddii sheyga ka baxo raad, ka dibna waxa uu ka kooban yahay zinc, taasoo muujinaysa in biraha tayo hooseeyo;
2. irbad astaantii - haddii bogagga lacagtii, baring aasaaskii biraha kale, ka dibna aad been abuur ah ka hor,
3. nuurad lahayn marmarin - ka dib markii xiriir si lacag bilaabo inuu blacken aan nuurad lahayn (shaqeysiin wata lacag iyo walxaha);
4. subagtaa oo cadar sulfuric iibiyo farmashiyada - hadda xiriir la mugdi ah lacag cawl (sida in kiiska la soo dhaafay, ka shaqayn kartaa xataa marka mowduuca si fudud in lacag). Color waa la dhimay ee maado ka dib markii karkaraya xal soodhaha leh gabal aliminiyum;
5. dareerin iodine - in xidhiidhka isaga iyo lacag jirsado madow, sare saamiga, falcelinta dhacdaa si degdeg ah. Waxa kale oo ay tahay in madow ah waxaa markii danbe aan maydhay off,
6. imtixaanka reaction kiimikada - dareerin nitric acid, ka dibna da'a in xal la mid ah cusbo, taasoo keentay in hoos u dhac waa inay ka muuqan dadajin curdy of chloride lacag ah (arag hoos weyneyso a). Haddii dadajin crystalline, ka dibna waxaan u horseedi chloride, iyo mawduuca waa been abuur ah.

Dadka qaarkood waxay awoodaan in ay aqoonsadaan urta oo lacag ah, laakiin hadda habkan u baahan tahay in ay ku tiirsanaadaan ka yar iyo wax ka yar, maxaa yeelay dhadhan ee biraha lagu lifaaqi karaa dhadhan sheyga.

Waxaan fursado dhowr ah oo ku saabsan sida si loo ogaado lacagtii guriga, si kastaba ha ahaatee, hab kasta, kuwaas oo u ogolaan khaladaad qaar ka mid ah, gaar ahaan haddii ay codsato xirfad laawe ah. Sidaa darteed, si loo ogaado tayada oo ka mid ah saamiga iyo lacag waxaa lagula talinayaa in aad la xiriirto dukaanka dahabka ama dhilif dukaan gaar ah, halkaas oo ay lacag yar ku siin doonaa jawaab sax ah su'aasha ah haddii sheyga waa lacag, lacag plated ama been abuur ah.
