Vim li cas lub ntsis ntawm cov hlau soldering ib txwm khiav upwards?
Qee cov neeg siv khoom tau tshaj tawm tias qhov ntxeev ntawm cov hlau soldering khiav thaum siv cov hlau soldering. Yog vim li cas?
Ua ntej teb cov lus nug no, cia txhua tus neeg nkag siab txog cov qauv ntawm lub taub hau hlau soldering. Lub taub hau soldering hlau yog tsim los ntawm tooj liab,
hlau, nickel, chromium, thiab tin. Cia peb nkag siab txog lub luag haujlwm ntawm ntau yam hlau.
Copper - Raws li cov khoom siv hluav taws xob, nws yog cov khoom tseem ceeb ntawm cov hlau taub hau.
Hlau - ua lub luag haujlwm tiv thaiv corrosion thiab yog qhov tseem ceeb cuam tshuam rau lub neej kev pab cuam ntawm lub taub hau hlau.
Nickel - ua lub luag haujlwm ntawm kev tiv thaiv xeb hlau plating.
Chromium - tsis lo rau tin, tiv thaiv tin los ntawm kev khiav mus rau lub cev ntawm cov hlau taub hau thaum siv.
Tin - nyob rau hauv lub taub hau, qhov twg lub tin yog siv.
Peb tuaj yeem nkag siab ntawm ib nrais muag tias yog vim li cas rau lub tin khiav yog cuam tshuam nrog chrome plating txheej. Yog tias chrome plating txheej nyias dhau lawm, tin yuav khiav. Feem ntau, qhov kawg ntawm cov hlau soldering yuav tsum tau chrome-plated rau ntau tshaj 5 feeb. Yog tias tus neeg siv khoom siv kub siab dhau lawm, lub sijhawm chrome-plating yuav tsum tau nce ntxiv. Qhov no yog ze ze rau qhov kub thiab txias ntawm lub taub hau soldering hlau.
