Dab tsi yog qhov ntsuas kub zoo rau cov hlau soldering?
Nruab nrab ntawm 350 degrees - 400 degrees.
Qhov kub ntawm lub taub hau hlau yog ntau tshaj 400, tab sis qhov kub ntawm qhov chaw sib cuag tsis yog ceev heev yog tias cov cua sov dissipation, qhov kub yuav maj mam nce, lub taub hau hlau thiab nws lub cev cua sov ntawm kev ua haujlwm kub (300 degree { {2}} degree ), tsuas yog ze rau me ntsis siab dua li qhov kub ntawm cov hlau nplaum (220 degree ).
Soldering hlau yog cov khoom siv hluav taws xob thiab hluav taws xob tswj xyuas cov cuab yeej tsim nyog, lub hom phiaj tseem ceeb yog vuam cov khoom thiab cov xov hlau, raws li cov qauv siv tshuab tuaj yeem muab faib ua endothermic soldering hlau thiab sab nraud kub soldering hlau, raws li kev ua haujlwm tuaj yeem muab faib ua tsis muaj. tin soldering hlau thiab suction tin soldering hlau, raws li kev siv sib txawv yog muab faib ua high-power soldering hlau thiab low-power soldering hlau.
Qhov dav dav ntawm cov hlau soldering yog dab tsi?
Yog hais tias nws yog tin soldering hlau, nws qhov kub siab tshaj plaws yog ntau tshaj 300 degrees, vim hais tias lub melting point ntawm tin yog 231.9 degrees, yog li ntawd welding aluminium yog tsis tau, lub melting point ntawm txhuas yog 660.2 degrees, welding aluminium yuav tsum tau siv. ua gas vuam.
Dab tsi yog qhov kub ntawm cov hlau soldering?
soldering hlau hauv vuam sib txawv, qhov kub thiab txias tsis zoo ib yam, vuam tooj liab thiab hlau, qhov kub thiab txias tsis zoo ib yam, nyob ntawm seb qhov xwm txheej tiag tiag.
Feem ntau nws yog nyob nruab nrab ntawm 350 degrees thiab 400 degrees, tsuav yog nws siab tshaj qhov melting point ntawm solder.
Qhov kub siab tshaj plaws yog feem ntau ntawm 480 degrees Celsius, tab sis feem ntau teem rau ntawm 320 txog 400 degrees rau nws, thiab tom qab ntawd siab dua, yog tias cov hlau taub yooj yim rau oxidize.
W tus lej loj kuj txiav txim siab nws qhov kub thiab txias:
220V
20W 400 degree
25W 450 degree
30W 500 degree
40W 530 degree
50W 580 degree
60W 600 degree
Kev kho cov khoom siv hauv tsev feem ntau yog nyob rau hauv 30W los yog li ntawd, cov tub ntxhais kawm 20W tuaj yeem ua tau.
