Ntau lub xov tooj cua muaj cov khoom muaj nqis thiab ib nrab zoo: nyiaj, kub thiab kub dawb. Koj tuaj yeem tawm cov hlau no tom tsev, tab sis qhov no yuav tsum muaj sijhawm thiab kev rau siab. Ib qho ntxiv, koj yuav xav tau qee yam reagents.
Cov Lus Qhia
Kauj ruam 1
Nqa cov kub plated tooj dag thiab tooj cua xov tooj cua. Ua kev tov ntawm hydrochloric thiab sulfuric acids (1 liter ntawm sulfuric acid nrog qhov ceev ntawm 1.8 g / cm3 thiab 250 ml ntawm hydrochloric acid nrog qhov ntom ntawm 1.19 g / cm3). Tshav tov rau qhov kub ntawm 60-70 degrees Celsius. Dhuav cov ntsiab lus rau hauv. Ntxiv me me ntawm nitric acid. Qhov tshwm sim "aqua regia" yuav yaj cov xim kub.
Kauj ruam 2
Thaum tsis muaj nitric acid, tshem cov kub plating los ntawm anodic dissolution hauv kev daws ntawm sulfuric lossis hydrochloric acid ntawm qhov kub ntawm 15 txog 25 degrees Celsius. Hauv qhov no, lub zog tam sim no yuav tsum yog 0.1-1 A / dm2, thiab lub cathode yuav tsum yog cov hlau lead lossis hlau. Koj pom tias tam sim no tau poob lawm - kub yog yaj.
Kauj ruam 3
Rub tawm cov platinum nrog nitric acid. Muab cov xov tooj cua los tso rau hauv nws platinum. Cov hlau zoo nkauj yuav nag lossis daus. Muab cov kua qaub rau hauv lwm lub khob. Nruab nrog cov av hauv nrog cov kua dej ci. Kub yuav tau rov qab zoo ib yam nkaus.
Kauj ruam 4
Tshem tawm cov nyiaj. Nqa tooj liab lossis tooj dag los ntawm xov tooj cua hauv cov nyiaj uas tau thov rau lub cev lossis chaw sib cuag. Ua kom muaj kev sib xyaw ua ke ntawm sulfuric acid thiab nitric acid (19 txog 1, 2). Rhaub qhov sib tov kom 80 degrees. Tshem tawm cov nyiaj ntawm cov tshuaj no los ntawm kev txo nws kom ntau npaum li cas ntawm cov zinc chips lossis hmoov av.
Kauj ruam 5
Ua tib zoo mloog cov ntsiab lus nyiaj hauv qee cov xov tooj cua. Cov nyiaj muaj nyob hauv tus nqi hnyav nyob hauv capacitors. Piv txwv li, K15-5 muaj 29, 901 grams, thiab K10-7 muaj 13, 652 grams. nyiaj (qhov muab xam rau 1000 daim). Koj tseem tuaj yeem nqa yuav luag txhua lub xov tooj cua ntawm lub caij nyoog hauv Soviet, lawv tseem muaj cov nyiaj hauv qhov txaus.
Kauj Ruam 6
Tshem tawm cov nyiaj ntawm qhov xa rov qab. Lawv muaj nws hauv nws daim ntawv huv. Piv txwv, hauv RES6 - 157 gr. nyiaj, thiab hauv RSCh52 nws cov ntsiab lus yog 688 grams, thiab hauv RVM qhov sib koom ntawm cov hlau ib nrab yog 897.4 grams. (cov ntaub ntawv raug muab rau 1000 daim).
Kauj Ruam 7
Thiab kawg li. Raws li koj tuaj yeem pom, cov xim muaj hlau yog tsuas yog rho tawm siv ntau cov kua qaub. Nws yog ib qho tsim nyog yuav tsum tau ua haujlwm nrog kua qaub kom zoo, saib xyuas txhua txoj cai kev nyab xeeb. Nco ntsoov, kua qaub tsis tsuas yog tsim kev phom sij yog tias nws raug rau daim tawv nqaij, koj tuaj yeem mob kub nyhiab txawm tias koj nqus tau nws cov vapors. Saib xyuas koj tus kheej!
