Muaj peb qhov xwm txheej uas lub tshuab hluav taws xob yuav tsis kub.
1. Txhim kho cov tub ntxhais hlau ntawm cov hluav taws xob hlau kom raug
Tom qab qee qhov cua sov sab hauv hom hluav taws xob soldering hlau tau hloov nrog cov tshiab soldering hlau cores, lawv muaj zog rau lub sijhawm ntev, tab sis qhov kub tsis nce. Tsis tuaj yeem txawm yaj tin, tus kov yog kub heev. Thaum kuaj xyuas, yog tias qhov hluav taws xob zoo li qub, koj yuav tsum tshem tawm cov tub ntxhais hlau soldering los xyuas seb qhov kev teeb tsa sab hauv puas tsim nyog.
Cov cua kub sab hauv hom soldering hlau core yog tib qhov ntev li lub plhaub sab nraud. Txoj kev txhim kho kom raug yog ua kom qhov kawg ntawm cov tub ntxhais hlau txuas nrog qhov kawg ntawm lub raj sab nraud, thiab tsis yog indent lossis protrude. Tsuas yog los ntawm kev ua kom zoo sib xws tuaj yeem ua kom sov tau zoo. mus rau qhov kawg ntawm cov hlau soldering.
Yog hais tias cov tub ntxhais hlau soldering yog retracted ntau, lub installation ntawm hluav taws xob cua sov tub ntxhais nyiam mus rau tus kov, uas ua rau lub tshav kub concentrated nyob rau hauv lub kov kawg, thiab lub tshav kub ntawm lub soldering hlau taub tsis tuaj yeem ncav cuag qhov kub ntawm melting tin.
2. Kev xaim ntawm cov tub ntxhais tshiab soldering hlau
Ib hom cua sov sab hauv soldering hlau core tau tawg tawm, thiab kev pabcuam lub neej tsis ntev txawm tias tom qab ob peb hloov.
Cov hlau lead ntawm qhov hloov tshiab soldering hlau core yog luv dhau. Tsis muaj chaw rau cov tub ntxhais hlau txuas kom nthuav dav thiab cog lus thaum nws txias thiab kub, uas ua rau cov hlau tsis muaj zog sab hauv yuav tawg thaum cov tub ntxhais hlau soldering txias thiab shrinks tom qab lub ntsaws yog unplugged.
Txoj kev hloov kom raug: ua kom cov hlau lead ntev me ntsis, 1-2mm, kom nws tsis yooj yim rau hlawv. Ua tib zoo saib xyuas kom tsis txhob xaim kawg ntawm qhov ntev dhau los kov cov xaim, thiaj li tsis ua rau qhov cuam tshuam luv luv.
3. Kho cov kab hluav taws xob tawg
Thaum cov hluav taws xob soldering hlau tsis kub, qhov tawg cua sov hlau yuav tsum tau kho. Hauv kev xaiv txoj kev kho, txoj kev sib tw yuav tsum tsis txhob siv.
Tom qab cov hlau kub los yog cov hauv paus hlau lead ntawm cov hluav taws xob soldering hlau raug txiav, nws feem ntau reconnected los ntawm txoj kev twisting. Qhov tsis zoo ntawm txoj kev no yog qhov kev sib cuag yog xoob thiab kev tiv thaiv kev tiv thaiv yog loj, uas yuav yooj yim ua rau ignition lossis thermal fuse.
Txoj kev txhim kho: Tshem tawm cov cua sov xaim, ua ntej tshem cov oxide ntawm qhov sib koom ua ke, tom qab ntawd ntswj kom nruj, thiab tom qab ntawd muab cov iav tawg me ntsis thiab cov khoom siv hluav taws xob ceramic (6: 1) hmoov nyob ib ncig ntawm qhov sib koom ua ke. Fais fab rau ob peb feeb tom qab kev teeb tsa, cov hmoov yog yaj thiab txuas rau cov neeg sib cuag, nws tsis yooj yim rau fuse, thiab nws yog ruaj khov.
Dab tsi yog qhov ntsuas kub ntawm cov hlau soldering?
Yog hais tias nws yog tinned hluav taws xob soldering hlau, nws qhov siab tshaj plaws kub yog li 300 degrees, vim hais tias lub melting point ntawm tin yog 231.9 degrees, yog li nws tsis muaj peev xwm solder aluminium, lub melting point ntawm txhuas yog 660.2 degrees, thiab welding aluminium yuav tsum tau. gas vuam.
Dab tsi yog qhov kub thiab txias ntawm cov hlau soldering?
Thaum lub tshuab hluav taws xob soldering hlau yog cov khoom sib txawv, qhov kub thiab txias yog qhov sib txawv, thiab qhov kub thiab txias yog qhov sib txawv thaum soldering tooj liab thiab soldering hlau, 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 480 degrees Celsius, tab sis feem ntau nws yog qhov zoo rau teeb rau li 320 ~ 400 degrees. Yog tias nws siab dua, qhov ntxeev ntawm cov hlau soldering yog yooj yim rau oxidize.
