Nri: Phosphoric acid bụ otu n'ime ihe mgbakwunye nri. A na-eji ya na nri dị ka onye na-ahụ maka utoojoo na nri yist. Coca-Cola nwere phosphoric acid.Phosphate bụkwa ihe mgbakwunye nri dị mkpa na enwere ike iji ya dị ka nkwalite nri.
N'elu igwe "ọgwụgwọ phosphorification". Ihe a na-akpọ phosphorus na-ezo aka na usoro a na-emepụta ihe ndị na-arụ ọrụ ígwè site na ngwọta acidic nwere dihydrogen -phosphate nnu, na usoro nke ịmepụta akpụkpọ anụ phosphate kwụsiri ike n'elu ya iji mepụta mmeghachi omume kemịkal. A na-akpọ akpụkpọ ahụ ahụ ihe nkiri phosphorum. Ebumnuche bụ isi nke ihe nkiri phosphorum bụ iji mee ka adhesion nke ihe nkiri mkpuchi na-eme ka ọ dịkwuo mma ma melite nkwụsị nke mkpuchi. E nwere ọtụtụ ụzọ isi mee phosphorous. Dị ka okpomọkụ n'oge phosphorusization, ọ nwere ike kewaa n'ime elu okpomọkụ phosphorus (90-98 Celsius C), ọkara okpomọkụ phosphorus (60-75 Celsius C), obere okpomọkụ phosphate (35-55 Celsius C) na N ụlọ okpomọkụ phosphorus.
A na-eji teknụzụ passivation nke ihe nkiri phosphorum eme ihe na North America na mba Europe. Ojiji nke teknụzụ passivation dabere na njirimara nke ihe nkiri phosphate n'onwe ya. Ihe nkiri phosphorum dị gịrịgịrị. N'ozuzu, ọ bụ 1-4g / m2, nke na-adịghị gafere 10g / M2, ya free pore ebe buru ibu, na ihe nkiri n'onwe ya nwere oke corrosion iguzogide. Ụfọdụ ọbụna ngwa ngwa nwere nchara edo edo n'oge usoro ihicha. Mgbe phosphorurativeization gasịrị, passivation na ọgwụgwọ mechiri emechi nwere ike ịmekwu oxidized site na ígwè ahụ ekpughere na pores nke ihe nkiri phosphorurative, ma ọ bụ na-emepụta oyi akwa passivation. Mmetụta oxidation na-eme ka phosphate guzosie ike na ikuku.
A na-eji ihe nkiri ntụgharị phosphate mee ihe na ígwè, aluminum, zinc, cadmium, na alloys ya, nke a pụrụ iji mee ihe dị ka oyi akwa ikpeazụ a nụchara anụcha ma ọ bụ dị ka etiti etiti nke mkpuchi mkpuchi ndị ọzọ. Ọrụ ya nwere akụkụ ndị a.
Ọ bụ ezie na Ịmalite phosphorurative film bụ mkpa, n'ihi na ọ bụ a na-abụghị metal na-adịghị na-eduzi iche oyi akwa, ọ nwere ike ịgbanwe ezi eduzi nke elu nke metal workpiece n'ime a oghom eduzi, inhibit guzobe micro-electrical n'elu. na metal workpiece Corrosion nke mkpuchi ihe nkiri.
