Kev siv cov hlau tooj liab tinning yog siv dav hauv kev tsim cov xov hlau, cov cables, thiab cov xov hlau enameled. Cov txheej tin yog ci thiab silvery dawb, uas tuaj yeem ua rau kom muaj peev xwm weldability thiab kho kom zoo nkauj ntawm tooj liab yam tsis cuam tshuam rau kev ua hluav taws xob. Nws tuaj yeem siv rau hauv kev lag luam hluav taws xob, rooj tog, ntim khoom noj, thiab lwm yam. Tiv thaiv kev oxidation, ua rau kom zoo nkauj ntawm cov khoom siv tooj liab. Tsis tas yuav siv cov khoom siv electroplating, tsuas yog yuav tsum tau ntub, yooj yim thiab yooj yim, thiab tuaj yeem plated nrog cov tin tuab. [1]

Kev taw qhia txog yam ntxwv
1. Cov hlau tooj liab uas muaj cov hlau nplaum zoo heev.

2. Raws li lub sijhawm hloov pauv, qhov kev sib txuas tseem zoo thiab tuaj yeem khaws cia rau lub sijhawm ntev.

3. Qhov saum npoo du, ci thiab noo noo.

4. Kev ruaj khov thiab txhim khu kev qha, ua kom zoo thiab muaj txiaj ntsig zoo.

Cov cim qhia txog lub cev thiab tshuaj lom neeg
1. Qhov hnyav tshwj xeeb: 1.04 ~ 1.05

2. PH: 1.0 ~ 1.2

3. Tsos: xim tsis muaj pob tshab kua

cov txheej txheem ntws
Kev tshem tawm cov roj ntawm cov khoom tooj liab - pickling lossis polishing - ob zaug ntxuav - electroless tin plating - peb zaug ntxuav - qhuav raws sijhawm nrog cua txias - kuaj.

Kev siv cov tshuaj pleev plating tsis siv hluav taws xob: Ntxiv 8 ~ 10g / kg ntawm cov tshuaj pleev plating rau hauv dej pleev plating ua ntej siv. Qhov kub ntawm cov tshuaj pleev plating yog qhov kub ib txwm ~ 80 ℃, thiab lub sijhawm ntawm cov tshuaj pleev plating yog 15 feeb. Thaum lub sijhawm ua cov tshuaj pleev plating, cov tshuaj pleev plating yuav tsum tau maj mam do lossis tig lub workpiece maj mam. . Kev rov ua kom noo dua tuaj yeem ua rau cov txheej tin tuab dua.

Cov kev ceev faj
Cov khoom siv tooj liab tom qab micro-etching yuav tsum tau muab tso rau hauv cov tshuaj tin plating hauv lub sijhawm tom qab ntxuav kom tiv thaiv qhov chaw tooj liab los ntawm oxidized dua thiab cuam tshuam rau qhov zoo ntawm cov txheej.

Thaum qhov ua tau zoo ntawm tinning poob qis, 1.0% tinning additive tuaj yeem ntxiv, thiab nws tuaj yeem siv tom qab do kom sib npaug.
