I-Copper inhibitor okanye i-copper deactivator iyisincedisi esisebenzayo esisetyenziswa kwizinto zepolymer ezifana neeplastiki kunye nerabha. Umsebenzi wayo oyintloko kukuthintela ukuguga kwempembelelo ye-catalytic yobhedu okanye i-ion zethusi kwizinto eziphathekayo, ukuthintela ukuthotywa kwezinto, ukuguqulwa kombala, okanye ukuthotywa kwepropathi ebangelwa kukudibana nobhedu. Kubaluleke kakhulu kwiinkalo ezifana ne-wire conduit, i-cable sheath, izinto zokupakisha ze-elektroniki, njl.
I-Copper kunye ne-alloys yayo (ezifana neengcingo) zisetyenziswa kakhulu ekuhanjisweni kwamandla, kodwa xa ubhedu ludibana ngqo nezinto ezithile zepolymer (ezifana ne-PVC, i-polyethylene), inokubangela ezi ngxaki zilandelayo:
I-Catalytic oxidation:
I-Cu2+ yi-catalyst eyomeleleyo ye-oxidation ekhawulezisa ukuphuka kwe-oxidative ye-polymer molecular chain, ngakumbi kwiqondo lokushisa eliphezulu kunye neendawo ezifumileyo.
Ukutya kweAcid:
Kwizinto ze-halogenated ezifana ne-PVC, ubhedu lunokusabela kunye ne-HCl ebolileyo ukuvelisa i-chloride yobhedu (CuCl2), i-accelerating material decomposition (self catalytic effect).
Ukuwohloka kwembonakalo:
Ukufuduka kweeyoni zethusi kunokubangela ukuba kubonakale amabala aluhlaza okanye amnyama (i-copper rust) ebusweni bezinto eziphathekayo, ezichaphazela ukubonakala kwayo.
Indlela yokusebenza yokucima
Ii-deactivators zicinezela iziphumo ezibi zobhedu ngokusebenzisa ezi ndlela zilandelayo:
Iiyoni zobhedu ezichetyiweyo:
Ukudibanisa ne-Cu2 + yamahhala, ii-complexes ezizinzileyo zenziwa ukuvimba umsebenzi wabo we-catalytic (njenge-benzotriazole compounds).
Ukugqithiswa komphezulu wobhedu:
Yenza ifilimu ekhuselayo phezu kobhedu ukukhusela ukukhutshwa kwe-ion zethusi (ezifana ne-organic phosphorus compounds).
Ukungathathi hlangothi kwezinto ezine-asidi:
Kwi-PVC, ezinye ii-deactivators ziyakwazi ukuphazamisa i-HCl eveliswe ngokubola, ukunciphisa ukubola kobhedu (ezifana ne-lead stabilizers ezinomsebenzi wokumelana nobhedu).
I-Copper Deactivators luhlobo lwe "Invisible Guardian" kwizixhobo zepolymer ezandisa kakhulu ubomi benkonzo yeemveliso ezifana neeshethi zocingo ngokuthintela umsebenzi we-catalytic wobhedu. Undoqo wetekhnoloji yayo ilele kwichelation echanekileyo yeekhemikhali kunye nokupasa komphezulu, ngelixa ulungelelanisa ubuhlobo bokusingqongileyo kunye nokusebenza kakuhle kweendleko. Kuyilo lwecasing yocingo, indlela yokulungelelanisa yeii-deactivators, ukunqanda amadangatyekunye nezinye izongezo ziyisitshixo sokuqinisekisa ukuthembeka kwexesha elide lezinto eziphathekayo.
