Copper inhibitor kapa koporo deactivator ke tlatsetso e sebetsang e sebelisoang linthong tsa polymer joalo ka polasetiki le rabara. Mosebetsi oa eona o ka sehloohong ke ho thibela ts'ebetso ea botsofali ea li-ion tsa koporo kapa tsa koporo ho lisebelisoa, ho thibela ho senyeha ha thepa, ho senya, kapa ho senyeha ha thepa ea mechine e bakoang ke ho kopana le koporo. E bohlokoa haholo masimong a kang terata, sheath ea cable, lisebelisoa tsa ho paka tsa elektroniki, jj.
Koporo le lisebelisoa tsa eona (tse kang lithapo) li sebelisoa haholo phetisong ea matla, empa ha koporo e kopana ka kotloloho le lisebelisoa tse itseng tsa polymer (joalo ka PVC, polyethylene), e ka baka mathata a latelang:
Catalytic oxidation:
Cu2+ ke sesebelisoa se matla sa oxidation se potlakisang ho robeha ha oxidative ea liketane tsa limolek'hule tsa polymer, haholo maemong a mocheso o phahameng le a mongobo.
Acid corrosion:
Linthong tse nang le halogenated tse kang PVC, koporo e ka 'na ea sebetsana le HCl e bolileng ho hlahisa koporo chloride (CuCl2), e ntseng e potlakisa ho senyeha ha thepa (self catalytic effect).
Ho senyeha ha chebahalo:
Ho falla ha li-ion tsa koporo ho ka etsa hore matheba a matala kapa a matšo (mafome a koporo) a hlahe holim'a thepa, a ama ponahalo ea eona.
Mochini oa ts'ebetso ea deactivator
Li-Deactivators li hatella litlamorao tse mpe tsa koporo ka mekhoa e latelang:
Li-ion tsa koporo tse chelated:
E kopantsoe le Cu2 + e sa lefelloeng, li-complexes tse tsitsitseng li thehoa ho thibela mosebetsi oa bona oa catalytic (joaloka metsoako ea benzotriazole).
Passivation ea copper surface:
Theha filimi e sireletsang holim'a koporo ho thibela ho lokolloa ha li-ion tsa koporo (joalo ka metsoako ea manyolo ea phosphorus).
Lintho tse nang le acidic tse sa nke lehlakore:
Ho PVC, li-deactivator tse ling li ka fokotsa HCl e hlahisoang ke ho bola, ho fokotsa ho bola ha koporo (joalo ka li-stabilizer tsa letsoai tse nang le letsoai tse nang le ts'ebetso ea koporo).
Li-Deactivator tsa Copper ke mofuta oa "Invisible Guardian" ka thepa ea polymer e eketsang haholo bophelo ba ts'ebeletso ea lihlahisoa tse kang li-sheathe tsa terata ka ho thibela ts'ebetso ea koporo. Moko-taba oa theknoloji ea eona o itšetlehile ka chelation e nepahetseng ea lik'hemik'hale le phallo ea holim'a metsi, ha e ntse e leka-lekanya botsoalle ba tikoloho le ho boloka litšenyehelo. Moqaping oa casing ea terata, mokhoa oa ho hokahanya oali-deactivators, e thibelang lelakabele li-additives tse ling ke senotlolo sa ho netefatsa ho tšepahala ha nako e telele ea thepa.
