Qeybta: arrimo kala duwan oo saameeya qiimaha guddiga PCB
Qiimaha PCB wuxuu had iyo jeer u ahaa halxiraalayaal dad badan oo iibsadayaal ah, dad badana waxay isweydiinayaan sida qiimayaashan loo xisaabiyo markii lagu soo bandhigo amarrada khadka tooska ah. Aynu ka hadalno qaybaha ka kooban qiimaha PCB si wada jir ah.
- Qalabka kala duwan ee loo adeegsaday PCB waxay horseed u tahay qiimaha kala duwan
Tusaale ahaan, golaha laba laab ee caadiga ah, saxanka guud ahaan wuxuu leeyahay fr4 (shrenge yi, Kingboard, Guoji, Saddex Qiironeed oo ka socota Saddex-meeryo, oo ah 3 oz, dhammaan 3 oz, dhammaantoodna ay ku jiraan wax qiimo ah oo ku saabsan farqi weyn u dhexeeya farqi weyn. In khad caabbinta khad, saliida caadiga ah ee saliida caadiga ah iyo saliida cagaaran ee cagaaran sidoo kale waxay ka jiraan farqi gaar ah oo qiimo leh.
Nidaamyada daaweyn ee dusha sare ee daaweyntu waxay u horseedaan qiimo kala duwan
Habka Daweynta Dusha Dabka ee caadiga ah: Option (oksidation iska caabbinta), waxaa jira hasl, deegaanka, jawiga ah), dahabka dahabka ah, oo ah billaha isku-darka ah, iyo sicirka nidaamka, iyo sicirka nidaamka ayaa ka qaalisan mustaqbalka.
3.pcb lafteeda oo ay keento dhibaato kaladuwan ee kala duwanaanta qiimaha.
Waxaa jira 1000 godad labada gole oo wareega wareega. Haddii cabirka godku yahay mid ka badan 0.2mm, cabirka godka ee guddiga kale uu ka yar yahay 0.2mm. Haddii laba nooc oo ah godad wareega ah ay isku mid yihiin, laakiin ballaadhka ballaadhka iyo dheecaanka xariiqda ayaa ka duwan, mid ayaa ka weyn 4mil kalena wuu ka yar yahay 4mil, waxay sababi doontaa kharash wax soo saar oo kaladuwan. Marka xigta wali ma lugeeyo qaabeynta qulqulka farshaxanka farta caadiga ah sidoo kale waa in lagu daro lacag aruurinta, tusaale ahaan godka badh, god indha la ', godka suxuunta, sarkaalka saxda ah, sarkaalka karbon ee lagu daabaco.
