Kub, nyiaj thiab lwm yam khoom muaj nqi yog muaj nrog cov khoom me me hauv cov xov tooj cua, feem ntau ntawm cov caij nyoog Soviet. Muaj qee txoj hauv kev ntawm kev tshem cov hlau los ntawm cov chaw zoo li no uas koj tuaj yeem siv nyab xeeb hauv tsev.
Cov Lus Qhia
Kauj ruam 1
Thaum rub tawm cov kub, thawj zaug kom pom meej cov txiaj ntsig zoo ntawm cov hlau hauv ib lossis lwm qhov xov tooj cua. Tus nqi ntawm ib feem thaum yuav khoom thiab tus nqi ntawm reagents yuav nyob ntawm seb nws ntau npaum li cas.
Kauj ruam 2
Kev yuav cov xov tooj cua, tshaj tawm hauv ntawv xov xwm, Is Taws Nem, qhia tias koj yuav yuav cov xov tooj cua, koj tsis tas yuav hais tshwj cov npe ntawm cov khoom muaj nqi, qhov no tuaj yeem tsim teeb meem ntxiv rau koj.
Kauj ruam 3
Tshem tawm kub ntawm tooj liab thiab tooj dag los ntawm anodic dissolution hauv sulfuric lossis hydrochloric acid ntawm qhov kub ntawm 17 txog 25 degrees. Cov ntom ntom tam sim no yuav tsum yog 0.1-1.0A ib square ntsuas. Siv cathode - hlau lossis txhuas. Kev txiav txim siab qhov kawg ntawm kev rov qab los ntawm kev poob qis hauv lub zog tam sim no.
Kauj ruam 4
Lwm txoj kev siv cov kua qaub. Siv 1L ntawm sulfuric acid thiab 0.25L ntawm hydrochloric acid. Rhaub qhov sib tov kom 60 degrees, muab cov roj los tso rau hauv qhov sib tov thiab ntxiv me me ntawm nitric acid. Qhov tshwm sim yog qhov hu ua "aqua regia", uas yog ib qho lees paub rau cov kub.
Kauj ruam 5
Txhawm rau tshem tawm cov nyiaj, ua ntej tshem tawm cov ntaub ntawv txhuas nrog cov pliers, cais cov sib txuas lus tiv tauj. Tom qab ntawd tshem cov nyiaj sib cuag nrog txiab.
Kauj Ruam 6
Txhawm rau tshem tawm cov nyiaj los ntawm tooj dag thiab tooj liab, tso cua sov ntawm kev daws ntawm nitric thiab sulfuric acids, coj hauv qhov sib piv ntawm 1.2 txog 19. Nqa qhov kub kom txog 80 degrees. Yav tom ntej, koj tuaj yeem rub tawm cov nyiaj los ntawm cov tshuaj no los ntawm kev txo nws nrog zinc hmoov av lossis pliaj. Koj tseem tuaj yeem siv acidification ntawm electrolyte nrog kev txhaj tshuaj me me ntawm hydrochloric acid. Thov nco ntsoov tias qhov haujlwm no yog qhov txaus ntshai heev, yog li nqa tawm nws tsuas yog hauv qhov tshwj xeeb fume hood.
Kauj Ruam 7
Nyiaj yuav khom nyob rau hauv daim ntawv ntawm ib tug dawb curd precipitate - silver chloride. Cia nws zaum tsawg kawg ib hnub. Tom qab ntawv xyuas rau tiav ntawm sedimentation. Ua li no, ntxiv cov tshuaj hydrochloric acid rau cov qauv lim dej. Lim cov nag lossis daus los ntawm daim ntaub tuab, yaug thiab qhuav ntawm qhov kub ntawm 105 -120 degrees.
Kauj ruam 8
Txhawm rau ua haujlwm los txhawm rau tshem tawm cov khoom muaj nqis los ntawm cov xov tooj cua, koj yuav xav tau: hydrochloric, sulfuric thiab nitric acid, zinc plua plav lossis plua plav, txhuas, hlau, ammeter, tshwj xeeb tais, txiab, hlau txiav, tuab daim ntaub, hnab looj tes.
