Ntau tus neeg siv cov hlau zoo tib yam soldering thiab tin solder mus rau tooj dag tooj dag, tab sis hom no muaj peb qho tsis zoo: ib qho pom tau yooj yim dua, uas tseem muaj qhov tsis muaj zog heev, tin thaum lub sij hawm blackening tuaj yeem coj tus cwj pwm txawv ntawm tooj dag, thiab tom qab ntawd lub seam yuav tig ib qho xim sib txawv. Siv cov ntawv ci tooj cua txoj kev siv cov roj teeb, tshwj xeeb cam thiab flux.
Nws yog qhov tsim nyog
- - roj-hlawv roj;
- - Nyiaj;
- - tooj liab;
- - asbestos puag;
- - graphite crucible;
- - borax;
- - boric acid.
Cov Lus Qhia
Kauj ruam 1
Ua ntej tshaj, ua qee cov cam. Nws yuav tsum muaj 2 feem ntawm cov nyiaj (cov nyiaj tau muab siv tau) thiab 1 feem ntawm tooj. Alloy ob qho tag nrho cov hlau nrog cov roj hlawv, rau qhov no siv qhov yuav tsum muaj ntawm ob qho hlau, tso lawv rau hauv graphite crucible thiab ua kom kub nws tag nrho nrog lub qhov cub hlawv. Tom qab cov hlau tau yaj, do nrog hlau xaim. Qhov muag muaj nyiaj. Tam sim no txias nws, ntxeev nws rau ntawm qhov thaiv thiab txiav ua tej daim me me.
Kauj ruam 2
Nqa cov hmoov borax (20 grams) thiab boric acid (kuj muaj hmoov, txog 20 grams). Do qhov sib tov, ncuav nyob rau hauv ib khob dej thiab rhaub kom yaj nws zoo dua. Tus flux tau npaj tiav. Tsis txhob ntshai, boric acid yuav tsis ua mob rau koj ob txhais tes lossis khoom siv.
Kauj ruam 3
Tam sim no mus ncaj qha rau soldering. Muag rau ntawm cov khoom kub-tiv taus xws li phaj asbestos. Tso cov tog rau soldering rau nws, ya raws lawv nrog flux, maj mam nphoo nrog ham daim pib thiab pib ua kom sov sov, ua ntej cov ham yuav chob qhov chaw, thiab tom qab ntawd kub nws kub-kub (txog 700 degrees). Qhov tseem ceeb ntawm no yog tiv thaiv kom txhob kub dhau, vim tias qhov sib txawv ntawm qhov muab yaj ntawm cov yaj thiab tooj dag tsuas yog 50 degrees. Kuj tseem nco ntsoov tias cov seem me ua kom nrawm dua li qhov loj dua, yog li ntawd maj mam kub kom lub qhov loj ua kom sov thiab qhov me me tsis yaj.
Kauj ruam 4
Cov kauj ruam kawg yog tshem cov flux residues los ntawm qhov khoom. Txhawm rau ua qhov no, tsuas yog yaug cov khoom hauv cov dej kub 3% sulfuric acid tov. Tsuas khi qee yam uas yuav tsis cuam tshuam nrog cov kua qaub rau lub ris tsho, tsau cov ris tsho hauv cov kua qaub rau ob peb feeb, tom qab ntawd yaug nrog dej ntws. Thov nco ntsoov tias nrog txoj kev melting no, tsis tuaj yeem siv cov hlau uas muaj hlau, vim tias qhov chaw yaj tag ntawm cov kub yog 700 degrees, thiab cov hlau muab hlau tsuas yog 200-250 xwb.
