Marka guddiga PCB la baakeeyo oo la raro ka dib kormeerka alaabta ugu dambeysa, looxyada ku jira dalabaadka dufcada, soosaarayaasha guddiga wareegyada guud waxay sameyn doonaan alaab badan ama waxay u diyaarin doonaan qaybo badan oo dheeri ah macaamiisha, ka dibna baakadaha faakiyuumka iyo kaydinta ka dib qayb kasta oo dalab ah. waa la dhamaystiray.Soo rarida sugaysaHaddaba maxay tahay sababta looxyada PCB-gu ugu baahan yihiin baakad vacuum ah?Sidee loo kaydiyaa baakad vacuum ka dib?Intee in le'eg ayay nolosheeda shelf?Xiaobian soo socda ee soosaarayaasha guddiga wareegga Xintonglian ayaa ku siin doona hordhac kooban.
Habka kaydinta guddiga PCB iyo cimrigiisa shelf:
Waa maxay sababta looxyada PCB ugu baahan yihiin baakad vacuum ah?Soosaarayaasha guddiga PCB-ga ayaa dhibkan muhiimad weyn siiya.Sababtoo ah marka guddiga PCB-ga aan si fiican loo xirin, dahabka immersion ee dusha sare, buufinta daasadaha iyo qaybaha suufka ayaa oxidize oo saameyn doona alxanka, taas oo aan ku habboonayn wax soo saarka.
Haddaba, sidee loo kaydiyaa guddiga PCB?Guddiga wareeggu kama duwana alaabooyinka kale, ma la xiriiri karo hawada iyo biyaha.Marka hore, faakuumka guddiga PCB ma dhaawacmi karo.Marka la xirxiro, lakabka filimka xumbo wuxuu u baahan yahay in lagu hareereeyo dhinaca sanduuqa.Nuugista biyaha ee filimka xumbada ayaa ka fiican, taas oo door wanaagsan ka ciyaarta ilaalinta qoyaanka.Dabcan, kuul aan qoyaanka lahayn ayaa sidoo kale lama huraan ah.Ka dib kala sooc oo ku calaamadee.Xiritaanka ka dib, sanduuqa waa in laga soocaa derbiga oo lagu kaydiyaa meel qallalan oo hawo leh oo ka fog dhulka, waana in sidoo kale laga ilaaliyaa iftiinka qorraxda.Heerkulka bakhaarka waxaa sida ugu wanaagsan loo xakameynayaa 23± 3℃, 55± 10% RH.Xaaladahan oo kale, looxyada PCB ee leh daawaynta dusha sare sida dahabka immersion, electro-dahab, daasad buufin, iyo dahaadh qalin ah ayaa guud ahaan lagu kaydin karaa 6 bilood.Looxyada PCB ee leh daawaynta dusha sare sida daasadda immersion iyo OSP guud ahaan waxa la kaydin karaa 3 bilood.
Looxyada PCB-ga ee aan la isticmaalin muddo dheer, waxay u fiican tahay soosaarayaasha guddiga wareegyada inay ku rinjiyan lakabka rinjiga saddex-cadayga ah.Shaqooyinka rinjiga saddexda ah ayaa ka hortagi kara qoyaanka, boodhka iyo oksaydhka.Sidan, nolosha kaydinta guddiga PCB waxaa lagu kordhin doonaa 9 bilood.
