II. Kiyayewa da ajiyewa na PCBs a yankuna daban-daban
Ƙayyadadden lokacin ajiya da zafin jiki na PCB ba kawai suna da alaƙa da ƙarfin samarwa da tsarin samarwa na masana'antun PCB ba, har ma suna da kyakkyawar dangantaka da yankin.
PCB da tsarin OSP ya yi da tsantsar zinari mai nutsewa gabaɗaya yana da tsawon rayuwar watanni 6 bayan marufi, kuma gabaɗaya ba a ba da shawarar yin gasa don tsarin OSP ba.
Lokacin adanawa da yin burodi na PCB yana da alaƙa da yankin. A kudu, gabaɗaya zafi yana da nauyi, musamman a Guangdong da Guangxi. A watan Maris da Afrilu na kowace shekara, za a sami yanayin "komowa kudu", wanda ke da gajimare da ruwan sama a kowace rana. Ci gaba, yana da ɗanɗano sosai a wannan lokacin. PCB da aka fallasa zuwa iska dole ne a yi amfani da shi a cikin sa'o'i 24, in ba haka ba yana da sauƙi don oxidize. Bayan budewa na al'ada, yana da kyau a yi amfani da shi a cikin sa'o'i 8. Ga wasu PCBs da ake buƙatar toya, lokacin yin burodi zai fi tsayi. A cikin yankunan arewa, yanayin gabaɗaya ya bushe, lokacin ajiyar PCB zai yi tsayi, kuma lokacin yin burodi na iya zama guntu. Yawan zafin jiki na yin burodi shine 120 ± 5 ℃, kuma an ƙayyade lokacin yin burodi bisa ga takamaiman halin da ake ciki.
