Yog vim li cas thiab cov kev daws teeb meem rau qhov tshwm sim ntawm perforation nyob rau hauv lub T12 soldering hlau taub
Cov hlau taub hau perforation yog qhov tshwm sim corrosion. Lub ntsiab lus tseem ceeb ntawm cov hlau nplaum yog tooj liab, thiab hlau plating yog siv los tiv thaiv qhov chaw. Cov hlau soldering yuav xeb ntawm qhov kub siab vim tias lub taub yog perforated. Tus nqi ntawm oxidation nce nrog nce kub. Yog li, txhawm rau lav qhov kev xav tau ntawm vuam, qhov vuam yuav tsum tau ua ntawm qhov kub thiab txias li sai tau. Khaws lub taub hau ntawm lub taub hau kom zoo thiab siv nws kom raug yog tus cwj pwm zoo. Lub hauv paus qauv ntawm cov hlau taub hau yog thawj qhov ua rau ntawm qhov perforation ntawm cov hlau taub hau.
1. Lub teeb dawb T12 soldering hlau taub hau muaj corrosion hnyav thiab tooj liab to vim yog siv dav. Ib lub tsho tshiab tshiab tseem muaj txiaj ntsig yog tias nws kub sab nraud! Txawm tias tom qab sawv hauv qhov tuag rov qab los, nws tseem spanking tshiab!
Disadvantages: Kuj tseem muaj qhov tsis zoo. Qhov kub thiab txias rov qab ceev nrawm dua li 936, tab sis lub tinning pace yuav qeeb dua thaum nws pib ua ntej, cua kub ceev yuav qeeb dua thiab raug nqi ntau dua, thiab lwm yam. Muaj ob qho txiaj ntsig thiab qhov tsis zoo.
2. Siv cov ntaub ntawv los kho lub taub hau perforated thiab hloov mus rau cov duab koj xav tau.
Cons: Muab ib txheej ntawm cov hlau yog txaus, thiab kev soj ntsuam nrog cov pob qij txha loj heev tseem siv tau. Cov tooj liab sai sai oxidizes tom qab rhuab thiab ntog tawm hauv ib lub sij hawm luv luv. Cov tooj liab ntshiab muaj lub neej ua haujlwm luv luv thiab yooj yim oxidized thiab corroded.
3. Sau cov electrode nrog borax. Kuv yuav ib tug tooj liab electrode nrog nyiaj nyob rau hauv nws (nco ntsoov tias nws yog ib tug silver-muaj tooj liab electrode). Yog li ntawd, ib qho teeb meem tseem ceeb nrog kev vuam tau pom. Tom qab vuam, cov nyiaj muaj electrode tsuas yog silvery raws li tus thawj t12 txheej. Raws li kev kwv yees, nws muaj qhov tshwj xeeb siab toughness thiab yooj yim heev rau tin vim cov nyiaj concentration. Cov neeg uas ua tau raws li qhov yuav tsum tau ua tuaj yeem ua rau nws sim. Tsuas yog ib qho me me xwb yuav tsum tau sau cov perforation hauv lub taub hau siv los txuas nws.
Cov kua nplaum muaj peev xwm yaj cov nyiaj los yog tooj liab. Kuv txhawj xeeb tias nws yuav corrode sai yog tias cov hlau txheej ntawm qhov chaw puas lawm thiab cov tooj liab nyob rau hauv dissolves tawm, tshwj xeeb tshaj yog thaum nws yog siv los solder tam sim no tsis muaj hlau lead-dawb hlau solder. Cov horns muaj cov hniav zoo li corrosion. Txuas ntxiv mus siv cov khoom xyaw uas tsis muaj kuab lom rau cov khoom ua kom pom tseeb.
