Inhibitor yumuringa cyangwa deactivator yumuringa ninyongera ikora ikoreshwa mubikoresho bya polymer nka plastiki na reberi. Igikorwa cyacyo nyamukuru nuguhagarika gusaza ingaruka za catalitiki zumuringa cyangwa umuringa ion kubikoresho, kwirinda kwangirika kwibintu, guhindura ibara, cyangwa kwangirika kwimitungo iterwa no guhura numuringa. Ni ingenzi cyane mubice nkumuyoboro winsinga, umugozi wumugozi, ibikoresho byo gupakira ibikoresho bya elegitoroniki, nibindi.
Umuringa hamwe nuruvange (nkinsinga) bikoreshwa cyane mugukwirakwiza amashanyarazi, ariko iyo umuringa uhuye neza nibikoresho bimwe na bimwe bya polymer (nka PVC, polyethylene), birashobora gutera ibibazo bikurikira:
Okiside ya Catalitike:
Cu2 + ni umusemburo ukomeye wa okiside wihutisha kuvunika kwa okiside yiminyururu ya polymer, cyane cyane mubushyuhe bwinshi nibidukikije.
Kwangirika kwa Acide ：
Mubikoresho bya halogene nka PVC, umuringa urashobora kwitwara hamwe na HCl yangirika kugirango ubyare chloride y'umuringa (CuCl2), bikarushaho kwihuta kubora (ingaruka za catalitiki).
Kugaragara kugaragara:
Kwimuka kwa ion z'umuringa birashobora gutuma ibibara byatsi cyangwa umukara (ingese y'umuringa) bigaragara hejuru yibintu, bigira ingaruka kumiterere yabyo.
Uburyo bwibikorwa bya deactivator
Gukuraho ibintu birwanya ingaruka mbi z'umuringa hakoreshejwe uburyo bukurikira:
Umuringa ukonje:
Uhujwe na Cu2 + yubusa, hashyizweho ibigo bihamye kugirango bahagarike ibikorwa byabo bya catalitiki (nkibintu bya benzotriazole).
Passivation yubuso bwumuringa:
Kora firime ikingira hejuru yumuringa kugirango wirinde kurekura ion z'umuringa (nk'imyunyungugu ya fosifore).
Gutesha agaciro aside aside:
Muri PVC, abadivantisiti bamwe barashobora gutesha agaciro HCl ikorwa no kubora, bikagabanya kwangirika kwumuringa (nka stabilisateur yumunyu wa sisitemu nayo ifite imikorere yo kurwanya umuringa).
Gukuraho umuringa ni ubwoko bwa "Invisible Guardian" mubikoresho bya polymer byongerera cyane ubuzima bwibicuruzwa nkibiti byinsinga muguhagarika ibikorwa bya catalitiki yumuringa. Intandaro yikoranabuhanga ryayo iri muburyo bwa chelation ya chimique na passivasi yubutaka, mugihe iringaniza ibidukikije no gukoresha neza. Mugushushanya insinga, guhuza formula yagukuraho, flame retardantnibindi byongeweho nurufunguzo rwo kwemeza igihe kirekire kwizerwa ryibikoresho.
