Txhawm rau kho cov hniav nyiaj hniav kub thiab lwm yam hniav nyiaj hniav kub, nws yog qee zaum tsim nyog cam qhov chaw ntawm cov khoom kub. Qhov no kuj tseem xav tau rau kev txum rov qab ntawm cov khoom siv qub txeeg qub teg, cov ntu ntawm cov uas tau kuj tau nquag ua cov khoom zoo. Thaum soldering, nws yog ib qho tseem ceeb kom tsis txhob txo cov ntsiab lus kub ntawm qhov khoom, lossis tsawg kawg yog kom tsis txhob txo tus nqi kev lag luam ntawm qhov khoom. Yog li no, tshwj xeeb solder siv los ham no refractory cov khoom. Lawv cov qauv nyob ntawm tus qauv ntawm kub.
Nws yog qhov tsim nyog
- - kub;
- - Nyiaj;
- - tooj liab;
- - cadmium;
- - soldering raj;
- - roj-hlawv roj;
- - Tus lwm yam me me;
- - Ntoo khaub lig rau kev npaj ntawm cov muag;
- - ntaub ntawv;
- - yeeb ncuab:
- - tus kws kho mob ntsuas nrog hnyav;
- - organic solvent (acetone, toluene, thiab lwm yam).
Cov Lus Qhia
Kauj ruam 1
Ua cov muag hauv qab no raws li cov qauv ntawm kub. Rau 72-carat kub, noj 750 qhov hnyav ntawm kub, 30 - nyiaj, 100 - tooj liab, 120 - cadmium. Rau 56 qhov tseeb kub koj xav tau: 585 qhov hnyav ntawm kub, 115 - nyiaj, 186 - tooj liab, 112 - cadmium. Rau kub daj (i.e. qib qis kub): 16 ntu los ntawm qhov hnyav ntawm kub, 21 - nyiaj, 11 - tooj. Rau kev yooj yim ntawm kev ua haujlwm, cov muag khoom tau tsim nyob rau hauv daim ntawv ntawm cov xaim nyias.
Kauj ruam 2
Ua ntej soldering, ntxuav qhov seam ntawm txhua qhov kev sib kis nrog cov kuab tshuaj organic. Kub tsis tsim oxides, yog li tsis tas yuav siv cov fluxes.
Kauj ruam 3
Soldering yog nqa tawm siv lub raj soldering (fevki). Nws yog cov hlau raj ntev txog 20 cm. Rau kev yooj yim, nws tuaj yeem khoov me ntsis ntawm ib kawg. Qhov kawg no tau siv qhov me me (1 hli lossis tsawg dua) thiab ua haujlwm kom tawg cov nplaim taws los ntawm cov nplaim taws lossis cov pa taws. Cua tshuab mus rau lwm qhov kawg ntawm lub raj xa dej los ntawm qhov ncauj lossis lub tshuab pa me me.
Kauj ruam 4
Clamp cov ntu yuav soldered me me pov lossis lwm clamp thiab dlhos. Ua kom sov siab khi nrog lub dav hlau ntawm nplaim taws tshuab tawm los ntawm lub raj soldering. Xaws cov hlau cam rau hauv cheeb tsam soldering. Tso cai rau qee cov solder ntws dhau lub weld. Tom qab ntawd cia cov khoom txias.
Kauj ruam 5
Tshem tawm solder nrog cov xaim me me cutters. Yog tias tsim nyog, ntxuav cov leeg nrog daim ntawv. Sau sawdust. Lawv tuaj yeem siv los ua solder, vim cov muag rau cov khoom kub yog kim heev.
