Vim li cas cov xov tooj tooj liab hauv qee cov xov hlau thiab cables tig daj?

Hauv kev nkag siab, kev lag luam xaim thiab cable yog kev lag luam ntawm cov khoom tiav thiab sib dhos. Ua ntej, tus nqi ntawm cov khoom siv yog loj, thiab cov nqi ntawm cov khoom siv cable suav nrog 80-90 feem pua ​​​​ntawm tag nrho cov nqi tsim khoom; Thib ob, muaj ntau hom thiab ntau yam ntawm cov ntaub ntawv siv, thiab cov kev xav tau ntawm kev ua tau zoo yog qhov tshwj xeeb. Piv txwv li, tooj liab rau conductors yuav tsum tau purity ntawm tooj liab. Ntawm ntau dua 99.95 feem pua ​​​​, qee cov khoom yuav tsum tau siv cov pa oxygen -dawb high-purity tooj liab; Thib peb, kev xaiv cov ntaub ntawv yuav muaj kev txiav txim siab ntawm kev tsim khoom, kev ua haujlwm ntawm cov khoom thiab kev pabcuam lub neej. Ntawm lawv, kev xaiv ntawm tooj liab hlau yog qhov tseem ceeb tshwj xeeb. Yog tias kev tsis saib xyuas me ntsis tuaj yeem ua rau muaj kev nyab xeeb, nws tseem ceeb heev kom nkag siab txog qee qhov teeb meem ntsig txog tooj liab nyob ntawm cov xov hlau thiab cov cables.

Yellowing feem ntau tshwm sim los ntawm cov laj thawj hauv qab no

1. Qhov kub ntawm lub cub tawg yog siab dhau lawm thiab lub fluidity yog loj, ua rau cov pinholes loj heev nyob rau hauv txheej txheej thiab ceev nkag ntawm tooj liab thiab tin.

2. Lub tin txheej yog nyias heev, thiab kev nkag mus ntawm tooj liab thiab tin yog ceev

3. Muaj ntau ntau halogen residues nyob rau hauv lub flux, thiab lub pickling ntawm tooj liab nto tsis meej txaus.

4. Lub sij hawm ntim yog ceev heev, cua sov tsis dissipated, thiab muaj ntau impurities nyob rau hauv lub cub tawg.

5. Qhov zoo ntawm cov khoom siv tooj liab tsis zoo txaus, thiab muaj ntau yam impurities

6. Qhov kub thiab txias muaj kev cuam tshuam rau kev ua ntawm tooj liab atoms, thiab nws tig daj sai dua nyob rau hauv cov hnub kub tshaj nyob rau hauv txias hnub.

Qhov teeb meem no yog daws raws li nram no

1. Txoj kab uas hla ntawm cov pwm yog ntau tshaj qhov kab ntawm txoj kab ntxiv rau 0.02mm (lub hom phiaj yog yooj yim heev, thiab cov txheej yuav tsum tsis txhob nyias dhau);

2. Muab tso rau ib sab li 2 teev tom qab tsim khoom thiab ntim nws (lub hom phiaj: sab hauv cov cua sov dissipation)

3. Yuav cov flux zoo thiab phim qhov concentration ntawm cov flux, feem ntau vim tias cov flux cuam tshuam rau qhov zoo ntawm tin plating;

4. Xaiv cov pa oxygen zoo dua - tooj liab dawb;
