Ị maara ihe na-ọrụ nke PCB  akwedokt ngwọta bụ? Isi nzube nke akara nke PCB plating ngwọta bụ na-niile chemical mmiri n'ime nso kpọmkwem site na usoro. The chemical na n'ụzọ anụ ahụ Njirimara nke mkpuchi na-mbo ihu na n'ime afọ kpọmkwem na usoro. E nwere ọtụtụ ụdị nke usoro eji na-achịkwa, gụnyere chemical fractionation, anụ ahụ ule, acid uru mkpebi siri ike nke ihe ngwọta, kpọmkwem nnukwu mpo nke ngwọta ma ọ bụ colorimetric mkpebi siri ike.

Ọzọ njikwa na-agụnye mkpebi siri ike nke mmako etoju na mgbanwe, filtration na ịdị ọcha. Ndị a kwesịrị ịna-ọma "ka" si Holstein plating bath ule panel, wee nyochaa, nyochaa na inferred si efere mkpuchi nkesa obodo iji nweta ndozi ma ọ bụ mmeli mma na usoro. Nzọụkwụ nzube.

Akpa, PCB plating ule

The akara ụkpụrụ nke plating bath kwesịrị ịgụnye isi chemical mejupụtara nke bath. Iji nweta ezi ikpe, elu na a pụrụ ịdabere ule akwara na gbasara nyocha ụzọ na-achọrọ. Ụfọdụ baths na-mkpa iji inyeaka n'aka dị ka ji atụ ha kpọmkwem nnukwu mpo na acid uru (PH). Iji kpọmkwem edebe n'elu ala nke mkpuchi, kasị PCB emepụta ugbu a ịmụta usoro nke Holstein si uzo ule. The kpọmkwem ule usoro bụ ka tilt ule panel site 37 Celsius na otu n'ogologo dị ka ogologo n'akụkụ, na anode perpendicular na tinyere ogologo n'akụkụ. The mgbanwe anode-to-cathode anya ga nwere a mgbe nlele tinyere cathode, na n'ihi na nke ugbu a, tinyere ndị ule efere na-agbanwe mgbe nile. Si kwuo nke ugbu a nkesa nke ule efere, ọ bụ omume na ndị ọkà mmụta sayensị chọpụta ma na nke ugbu a njupụta na-eji na plating bath bụ n'ime nso kpọmkwem site na usoro. The kpọmkwem mmetụta nke mmako ọdịnaya na nke ugbu a njupụta na mmetụta na n'elu mkpuchi quality nwekwara ike ịdị na-eme.

Nke abụọ, PCB ekwe na-adịghị mma ule usoro:

Nke a na usoro na nakweere n'ihi na ọ na masks a dịgasị iche iche, nke na-ekpughe ihe n'akuku, na ya elu ma na ala na-ebupụta na-na-emegharị ka dielectric mmetụta n'ihi na vetikal udi. Site na nke a, nke ugbu a nso na dispersing ike nwere ike nwalere.

Nke atọ, ikpe na inference:

Site n'elu-e kwuru ule usoro, ọ bụ omume na-ekpe ikpe onu nke omume na ala ugbu a na mpaghara nke ule efere na oge nke plating site kpọmkwem ndekọ nke ule efere, na ya nwere ike ikpe na mmako a chọrọ na-kwukwara; na na elu ugbu a na mpaghara, na-plating na rụrụ.
