Brass na-eguzogide Dezincification (Ọnụ ego DZR) aghọwo ihe dị mkpa na ụlọ ọrụ plumbing, karịsịa maka ngwa valve. Ọnụọgụ ndị ọrụ na-ahọrọ Ọnụ ego nke DZR Brass Valves na-abawanye, na-egosi na ihe ndị mmadụ chọrọ maka ịdị mma mmiri na ihe valve na-abawanye ụba.
Kedu ihe bụ DZR Brass?
Ọnụ ego DZR(Na-eguzogide Dezincification) bụ ọla kọpa alloy pụrụ iche emebere ka ọ guzogide dezincification, usoro corrosion nke na-emebi bras ọkọlọtọ na mpaghara ụfọdụ.
Kedu ihe bụ Dezincification?
Didinfection, ma ọ bụ ihicha zinc, na-eme mgbe a na-ahọrọ zinc site na alloy brass, na-ahapụ a porous.
Ihe omume nke dezincification corrosion na bras nwere njikọ chiri anya na ọdịnaya zinc dị na ọla kọpa-zinc alloys.. Na-emekarị, mgbe ọdịnaya zinc dị n'okpuru 15%, corrosion dezincification eleghi anya ime; Otú ọ dị, a na-emebi ihe mgbochi mmebi nke alloy. Ịba ụba ọdịnaya zinc nwere ike ịkwalite ma ike na mgbochi mbuze nke alloy, ma ọ na-ebulikwa ohere nke dezincification corrosion.
Mgbe ọdịnaya zinc gafere 20%, zinc na-agbaze nke ọma na ngwọta mmiri. Usoro a na-ahapụ ihe owuwu ọla kọpa na-agbaji, na-eduga n'ibelata ike nke bras.
Ntọhapụ nke ọla na-adịkarị ka ọ na-eme na mmiri mmiri na ihe ngwọta nwere nnu, dị ka NaCl na CuCl2.
A na-enweta usoro nguzogide na DZR brass site na njikwa nke ihe mejupụtara alloy. Na-ejikọta obere ihe ndị dị ka As/Sb/P/B/Al na obere ụwa, na idowe oke ọla kọpa na-zinc kpọmkwem, mepụta alloy nke ọma na-egbochi ịcha zinc n'ọnọdụ mmiri.
