Txoj kev kho deg thiab txheej txheem ntawm tooj liab bar tooj liab raj

1. Xim lubtooj liab
Cov khoom siv tes ua no yog los tshem tawm cov khoom siv rov qab, tsis tshua siv tam sim no. Txheej txheem: Peb-theem AC Circuit Court tsheb npav yuav tsum tau pleev xim rau xim dub, thiab xim code yuav tsum muab tso rau hauv qhov chaw pom tseeb. Theem A yuav tsum daj, theem B yuav tsum ntsuab, thiab theem C yuav tsum liab. Cov kab nruab nrab lossis kab nruab nrab yuav tsum tau pleev xim nrog lub teeb xiav xim.
2. Tin plating ntawm tooj liab bar
Qhov zoo: kev paub tab. Lub voj voog ua haujlwm luv luv, feem ntau siv. Tsis muaj zog: ntev ntev ntawm cov plaub hau tsaus nti, tes ua tsis tau. Tsis muaj kev tiv thaiv ib puag ncig!
Txheej txheem ntws: polishing nto, tshem tawm roj thiab lwm yam pretreatment → dej ntshiab ntxuav → plating siab Pb-Sn alloy kais dej ntxuav → dej ntshiab huv → tin plating → kais dej tshuaj ntxuav → neutralization (Na2HPO4 + Na3PO4) → kais dej tsuag ntxuav → dip stearic acid → kais dej huv → ntxuav dej ntshiab
3. Copper bar coated nrog tus neeg sawv cev tiv thaiv
Qhov zoo: txhawm rau tswj cov tooj liab bar thawj xim, me ntsis qis dua tus nqi ntawm tin plating. Disadvantages: Lub voj voog ua haujlwm ntev.
Cov txheej txheem ntws: polishing ua ntej kho → ntxuav dej ntshiab → pickling passivation workpiece → ziab ya raws → JLR-510 kev tiv thaiv kev kho mob → ntws dej ntxuav → dej kub immersion (txog 100 ℃, siv rau cua sov workpiece, lub hom phiaj ntawm dej evaporation los yog ziab) → ziab → ntim kaw.
Cov yeeb nkab tooj liab tsis siv neeg winding thiab unwinding kab yog characterized nyob rau hauv hais tias nws muaj xws li ib tug winding ntaus ntawv, ib tug pab txhawb nqa, ib tug tu cov cuab yeej, leveling ntaus ntawv thiab ib tug winding ntaus ntawv uas yog successively teem raws txoj kev taug kev ntawm cov yeeb nkab tooj liab nyob rau hauv cov txheej txheem ntawm winding thiab unwinding. Nyob rau hauv tas li ntawd, lub unwinding ntaus ntawv, lub unwinding ntaus ntawv rau lub tooj liab raj unwinding; Copper tube yug ntaus ntawv, cov cuab yeej txhawb nqa yog siv los txhawb lub unwinding ntaus ntawv tom qab lub unwinding tooj liab raj;
