Ferrofluid - cov khoom uas ua kua nyob rau hauv ib txwm muaj xwm txheej, tab sis hloov tau khov thaum muaj cov khoom sib nqus. Kuv pom txoj hauv kev tshiab hauv kev ua tsev ferrofluid thiab kuv xav qhia rau koj paub. Qhov zoo ntawm kuv qhov haujlwm yog tus nqi. Nws yog txoj hauv kev pheej yig dua li lwm txoj hauv kev online thiab nws yog qhov yooj yim heev. Kuv cov ferrofluid tsuas yog ob qhov uas pheej yig, koj tsuas xav tau cov ntaub ntawv kaw tseg qub thiab lub raj mis ntawm acetone!
Kauj ruam 1: Cov ntaub ntawv
Koj tsuas yog xav tau ACETONE, kaw cov kab xev, ua noj roj thiab MAGNET. --- 500ml/16 hli oz. Acetone. (1.50 $) --- Acetone yog nplaim taws siab ceev faj nrog nws. Koj tuaj yeem tau txais nws ntawm lub khw muag khoom. Nws raug nqi ib ncig 2 $. --- 10 kab xev suab paj nruag lossis 4 kab xev video. (0.00 $) --- Siv cov nkauj qub los yog kaw cov vis dis aus kaw. Koj tuaj yeem tau txais lawv zoo nyob hauv qab daus… --- 5ml/0.2 fl. oz. Roj ua noj. (0.00 $) --- Txhua lub tsev muaj chav zais cia … Chav ua noj … --- 1 lub zog loj loj. (0.50 $) --- Koj tuaj yeem tau txais nws los ntawm ib tus neeg hais lus qub hauv koj lub tsev. Cia li muab nws cais thiab siv nws! CEEB TOOM: Nws yooj yim heev! TSEEM CEEB TSHAJ TSHAJ PLAWS: ACETONE yog qhov ua tau zoo thiab tsis muaj suab nrov! Ceev faj nrog nws!
Kauj Ruam 2: Npaj Cov Kab Xev
Kab xev: Daim kab xev nws tus kheej yog qhov yooj yim heev. Nws suav nrog cov khoom yas yas hauv paus, thiab sib raug rau lub hauv paus no yog txheej txheej ntawm ferric oxide hmoov. Cov oxide feem ntau yog sib xyaw nrog cov phau ntawv txhawm rau txuas nws rau cov yas, thiab nws kuj suav nrog qee yam ntawm cov roj nplua nyeem qhuav kom tsis txhob hnav lub tshuab kaw suab. Ferric oxide (Fe2O3) yog lwm cov hlau oxide. Maghemite lossis gamma ferric oxide yog cov npe uas siv rau cov tshuaj. Muaj ntaub ntawv ntau npaum li cas daim kab xev ua haujlwm: https://electronics.howstuffworks.com/cassette1.htm Txheej txheem: Peb xav tau cais Ferric oxide los ntawm cov kab xev yas. Acetone yuav yaj cov ntawv sib cais thiab cais Ferric oxide. Tab sis ua ntej peb yuav tsum tsoo thiab tsoo cov kab xev!
Kauj Ruam 3: Qhuav Binder thiab cais Fe2O3
Melting: Nrhiav lub tais loj txaus. Muab txhua daim kab xev tso rau hauv thiab sau lub tais nrog acetone. Tos ob peb teev. Koj yuav tsum kaw lub tais nrog qee yam kom acetone los ntawm kev ua pa.
Kauj Ruam 4: Sau Ferric Oxide
Sau ferric oxide: Tau txais cov hlau nplaum. Yob nws nrog ntawv lossis hnab yas (nws xav tau cais cov ferric oxide los ntawm cov hlau nplaum yooj yim). Sau tag nrho koj cov Fe2O3. Ua kom qhuav. Qhov kauj ruam 3: Yog tias tsis yog txhua tus oxide tau sib cais los ntawm kab xev koj tuaj yeem rov ua cov txheej txheem nrog acetone ob peb zaug kom tau txais txiaj ntsig zoo dua.
Kauj Ruam 5: Ua Cov Khoom
Sib tov nrog roj: Rau 1ml ntawm ferric oxide koj xav tau 1/3ml roj ua noj. Sib tov nws. Yog tias nws ua kom khov dej ib ntus dej thiab xab npum thiab sib tov txhua yam ntxiv. Nws yuav pab cov roj sib xyaw nrog oxide.
Kauj ruam 6: Txheej txheem cej luam
Magnetize ferro kua: Tsis txhob hnov qab ua kom muaj zog nqus koj cov kua ferro. Siv cov hlau nplaum loj dua. Cov hlau nplaum loj ferrite zoo dua li cov hlau nplaum neodymium me me muaj zog. Koj tau ua qhov nruab nrab zoo ferrofluid!
