I-Copper inhibitor noma i-copper deactivator iyisengezo esisebenzayo esisetshenziswa ezintweni ze-polymer ezifana namapulasitiki nerabha. Umsebenzi wayo oyinhloko ukuvimbela umphumela wokuguga we-copper noma ama-ion ethusi ezintweni, ukuvimbela ukuwohloka kwezinto, ukuguquguquka kombala, noma ukuwohloka kwempahla okubangelwa ukuthintana nethusi. Kubaluleke kakhulu emikhakheni efana ne-wire conduit, i-cable sheath, izinto zokupakisha ze-electronic, njll.
I-Copper nama-alloys ayo (njengezintambo) asetshenziswa kakhulu ekudluliselweni kwamandla, kodwa lapho ithusi lihlangana ngokuqondile nezinto ezithile ze-polymer (njenge-PVC, i-polyethylene), ingase ibangele izinkinga ezilandelayo:
I-Catalytic oxidation:
I-Cu2+ iyisisusa esinamandla se-oxidation esisheshisa ukuphuka kwe-oxidative kwamaketanga e-polymer molecular, ikakhulukazi kumazinga okushisa aphezulu nasezindaweni ezinomswakama.
I-Acid corrosion:
Ezintweni ezine-halogenated ezifana ne-PVC, ithusi lingasabela ne-HCl ebolile ukuze kukhiqizwe i-copper chloride (CuCl2), iqhubekisele phambili ukusheshisa ukubola kwempahla (umphumela wokuzenzela).
Ukuwohloka kokubukeka:
Ukufuduka kwama-ion ethusi kungabangela amabala aluhlaza noma amnyama (ukugqwala kwethusi) ukuthi avele ebusweni bezinto ezibonakalayo, okuthinta ukubukeka kwayo.
Indlela yokwenza ye-deactivator
Ama-Deactivators acindezela imiphumela emibi yethusi ngokusebenzisa izindlela ezilandelayo:
Ama-ion e-Copper Chelated:
Kuhlanganiswe ne-Cu2+ yamahhala, ama-complexes azinzile akhiwa ukuvimbela umsebenzi wabo we-catalytic (njengama-benzotriazole compounds).
I-passivation ye-copper surface:
Yakha ifilimu evikelayo ebusweni bethusi ukuvimbela ukukhululwa kwama-ion ethusi (njengama-organic phosphorus compounds).
I-Neutralizing acidic acid:
Ku-PVC, amanye ama-deactivators angakwazi ukwenza i-HCl ibe lula ekhiqizwa ngokubola, inciphise ukugqwala kwethusi (njengama-lead stabilizers abuye abe nomsebenzi wokumelana nethusi).
I-Copper Deactivators iwuhlobo "lwe-Invisible Guardian" ezintweni ze-polymer ezinweba kakhulu impilo yesevisi yemikhiqizo efana nama-wire sheathes ngokuvimbela umsebenzi we-catalytic wethusi. Umnyombo wobuchwepheshe bayo ulele kumakhemikhali anembile kanye nokuncishiswa kwendawo, kuyilapho kulinganisa ubungane bemvelo kanye nokusebenza kahle kwezindleko. Ekwakheni i-wire casing, ifomula yokuxhumanisa yeizicisha, i-flame retardantnezinye izithasiselo ziyisihluthulelo sokuqinisekisa ukwethembeka kwesikhathi eside kwezinto.
