Kev faib tawm ntawm cov hlau soldering thiab qee qhov kev coj ua yuav tsum tau ua ua ntej siv
Soldering hlau yog riam phom khawv koob rau cov neeg nyiam siv hluav taws xob, qhov vuam ntawm cov khoom siv txiav txim siab qhov zoo ntawm cov khoom, vuam tshuab yog los xyuas kom meej qhov zoo ntawm vuam, cov khoom zoo thiab kev ntseeg siab ntawm cov kev sib txuas yooj yim. Piv txwv li, nrog endothermic soldering hlau, sab nraud kub soldering hlau, thermostatic soldering hlau, tin soldering hlau, thiab lwm yam.
Endothermic soldering hlau: los ntawm kev sib txuas pas nrig, kov, caij nplooj ntoos hlav clip, hlau core, hlau taub hau thiab lwm yam khoom. Cov tub ntxhais hlau soldering yog muab tso rau hauv lub taub hau hlau, uas yog ua los ntawm nickel-chromium tsis kam xaim qhwv ib ncig ntawm lub raj plooj (porcelain tube).
Sab nraud kub hom soldering hlau: nws lub taub hau hlau yog nyob rau hauv cov tub ntxhais hlau, nrog zoo thermal conductivity ntawm tooj liab raws li lub substrate ntawm tooj liab alloy khoom thiab ua. Nws lub taub hau hlau tuaj yeem ua telescopic, yog tias koj xav tau qhov kub thiab txias dua, lub taub hau hlau yuav raug kho kom txo qhov taw tes, thiab rov ua dua, lub taub hau hlau hloov ntev dua.
Qhov kub thiab txias tsis tu ncua: nws lub taub hau taub hau muab tso rau hauv cov hlau nplaum hom thermostat, rau kev tswj lub sijhawm lub zog. Yog tias qhov vuam kub tsis siab, lub sijhawm vuam tsis ntev, tom qab ntawd siv qhov kub thiab txias ntawm cov hlau.
Suction tin soldering hlau: nws yuav piston hom tin sucker thiab soldering hlau yaj nyob rau hauv ib qho ntawm cov desoldering cov cuab yeej, saj zawg zog thiab yooj yim rau siv, ntau yam ntawm daim ntawv thov.
Ua ntej siv cov hlau soldering, nws yog qhov zoo tshaj los ntsuas qhov tsis kam ntawm lub hwj chim ntsaws los txiav txim seb puas siv tau cov hlau soldering. Yog tias qhov tsis kam yog ob peb txhiab ohms muaj, yog tias qhov tsis kam yog xoom lossis infinity, nws tsis tuaj yeem siv. Zero kuj qhia tau hais tias muaj ib tug luv luv Circuit Court nyob rau hauv lub soldering hlau, thiab infinite kuj qhia tau hais tias muaj ib tug tawg Circuit Court nyob rau hauv lub soldering hlau.
Qee qhov kev coj ua ua ntej siv cov hlau soldering
Rau thawj zaug siv cov tshiab soldering hlau, kom ntseeg tau tias lub taub hau ntawm lub soldering hlau ci, electrified cua sov melted solder thaum dipping rosin thiab ntau zaus nyob rau hauv kev sib cuag nrog lub solder hlau, lub taub hau ntawm soldering hlau tusyees coated nrog ib tug txheej ntawm solder. Lub hom phiaj ntawm kev ua li ntawd, tsis yog tsuas yog pab txhawb kev siv tom ntej, tab sis kuj los tiv thaiv cov hlau taub hau oxidation. Rau cov laus soldering hlau ua ntej siv cov kev kho mob, vim hais tias nws tau siv rau lub sij hawm ntev, qhov saum npoo ntawm lub taub hau hlau yuav muaj ib txheej ntawm oxide, ua rau lub taub hau hlau tsis yooj yim rau noj tin. Yog li tsuas yog cov oxides ntawm qhov chaw ntawm lub taub hau ntawm lub taub hau nrog cov ntawv xuab zeb zoo los yog cov ntaub ntawv tshem tawm, ua rau nws lub ntsej muag ci. Tom qab ntawd nruab ib qho tshiab soldering hlau kho, lub taub hau ntawm lub taub hau saum npoo sib npaug plated nrog ib txheej ntawm solder.
Oxygen nyob rau hauv qhov tseeb tsis muaj dab tsi ua nrog rau lub soldering hlau cua sov, lub soldering hlau los ntawm lub alternating tam sim no thiab cua sov melting solder hlau. Thiab tus neeg nug tau hais tias tej zaum yuav yog cov hlau tsis noj cov tin, uas yog vim cov hlau soldering tau siv ntev dhau lawm thiab tsis siv, qhov no yuav ua rau cov hlau nplaum oxidation thiab hlawv, ua rau nws lub neej ua haujlwm ntev. Nyob rau tib lub sijhawm, nws tseem yuav ua rau lub taub hau hlau rau lub sijhawm ntev cua sov thiab oxidation lossis hlawv kom tuag. Yog li ntawd, soldering hlau tsis noj tin lawm. Nyob rau hauv cov txheej txheem no tsis noj tin muaj cov tshuaj tiv thaiv oxidation, cov tshuaj thiab cov tshuaj tiv thaiv cov pa oxygen, uas cov pa oxygen muab oxygen. Nyob rau hauv cov xwm txheej ib txwm yog qeeb oxidation, tuaj yeem ua kom lub zog ntev ntev, qhov kub nce siab, uas muab cov tshuaj tiv thaiv oxidation muab cov tshuaj tiv thaiv, ua kom cov oxidation ceev ntawm cov hlau soldering hlau taub hau thiab cov tub ntxhais hlau.
