Marka guddiga PCB ay ka soo baxaan ka dib baaritaanka ka dib wax soo saarka kama dambeysta ah, ee looxyada ku jira amarada korantada, soo-saareyaasha guud ee guddiga, ka dibna waxay u diyaarin doonaan xirmooyin badan oo ka mid ah baakadaha iyo kaydinta ka dib marka wax kasta oo amarro ah la dhammaystiro. Sugaya dhoofinta. Marka muxuu guddiyada PCB ugu baahan yihiin baakadaha faaruqa ah? Sidee loo kaydiyaa ka dib xirmada faaruqa ah ka dib? Muddo intee le'eg ayay noloshu ku noolaanaysaa? Xiabian soosocda ee Xiabian ee Guddiga Guddiyada Guddiga ee Xinnonglian ayaa ku siin doona hordhac kooban.
Qaabka kaydinta ee Golaha PCB iyo Noloshiisa Shelf:
Maxay u baahan yihiin guddiyada PCB-ka ee baakadaha faaruqa ah? Soo-saareyaasha Gudiga PCB Soosaarayaasha ayaa ahmiyad weyn u leh dhibaatadan. Sababtoo ah mar haddii Golaha PCB uusan si fiican u xirneyn, dahabka dusha sare, dahabka birta, qaybaha suufka iyo qaybo ka mid ah oo ay saameyn ku yeelanayaan oo ay saameyn ku yeelanayso wax soo saarka.
Marka, sidee loo keydiyaa guddiga PCB? Guddiga wareega ah kama duwana badeecadaha kale, ma taaban karaan hawada iyo biyaha. Marka ugu horeysa, faaruqashada guddiga PCB ma dhaawici karaan. Marka xirxiran, lakabka filimka xumbada u baahan in lagu hareereeyo dhinaca sanduuqa. Isu nuugida biyaha ee filimka xumbada ayaa ka fiican, oo door wanaagsan ka ciyaara qoyaanka-caddeynta. Dabcan, guluubka-caddeynta-caddeynta sidoo kale waa lama huraan. Ka dib u kala sooc oo calaamadee. Kadib xiritaanka, sanduuqa waa in laga soocaa derbiga oo lagu kaydiyaa meel qalalan oo hawo leh oo ka fog dhulka, waana in sidoo kale laga ilaaliyaa iftiinka qorraxda. Heerkulka bakhaarka waxaa sida ugu wanaagsan loo xakameeyaa 23 ± 3 ℃, 55 ± 10% RH. Xaaladaha noocaas ah, looxyada PCB ee leh daaweyn dusha sare ah sida goynta dahabka, electro-dahabka, buufinta qalin, iyo plation plation, guud ahaan waxaa lagu keydin karaa 6 bilood. Guddiyada PCB ee leh daaweyn dusha sare ah sida wax lagu dhex geliyo tindo iyo Ospan ayaa guud ahaan lagu keydin karaa 3 bilood.
Loogu talagalay looxyada PCB ee aan loo isticmaalin muddo dheer, waxaa ugu wanaagsan soo-saareyaasha guddiga wareega si ay u rinjiyeeyaan lakabka rinjiga saddexda-caddeyn ah. Hawlaha rinjiga saddexda-caddayn waxay ka hortegi karaan qoyaanka, boodhka iyo oksikalka. Sidan, nolosha kaydinta ee guddiga PCB waxaa loo kordhin doonaa 9 bilood.
