The PCB bolodi Nthawi zambiri amamatiridwa ndi zigawo zingapo za utomoni, ndipo zojambulazo zamkati zamkuwa zimagwiritsidwa ntchito popanga mawaya, ndipo pali zigawo 4, 6, ndi 8. Pakati pawo, kubowola kumatenga 30-40% ya mtengo wa matabwa osindikizidwa, ndipo kupanga misa nthawi zambiri kumafuna zida zapadera ndi kubowola. Zobowola zabwino za PCB zimagwiritsa ntchito zida zabwino zomata simenti, zomwe zimakhala zolimba kwambiri, kulondola kwa dzenje lalitali, khoma labwino la dzenje, komanso moyo wautali.

Pali zinthu zambiri zimene zimakhudza dzenje udindo kulondola ndi dzenje khoma khalidwe pobowola. Nkhaniyi tikambirana zinthu zazikulu zimene zimakhudza dzenje udindo kulondola ndi dzenje khoma khalidwe pobowola, ndi maganizo lolingana zothetsera wanu Buku.
