Oghere okporo ụzọ anyanwụ kwesịrị ịbụ oyi-galvanized ma ọ bụ ọkụ-galvanized?

Ugbu a, eriri igwe Q235 adịchaghị mma bụ ihe kachasị ewu ewu makaokporo ámá anyanwụ. Ebe ọ bụ na ọkụ okporo ámá nke anyanwụ na-edokwasị ifufe, anyanwụ, na mmiri ozuzo, ogologo ndụ ha na-adabere n'ikike ha nwere iguzogide corrosion. A na-ejikarị igwe eji eme ihe iji meziwanye nke a.

E nwere ụdị ihe abụọ nke zinc plating: na-ekpo ọkụ na-ekpo ọkụ na oyi-mikpu galvanizing. N'ihi naokporo osisi ígwè galvanized na-ekpo ọkụna-eguzogide ọgwụ na corrosion, anyị na-enyekarị ndụmọdụ ịzụrụ ha. Kedu ihe dị iche n'etiti ikpo ọkụ na-ekpo ọkụ na nke oyi-atụ, gịnịkwa mere ogwe osisi galvanized na-ekpo ọkụ ji enwe nguzogide corrosion ka elu? Ka anyị leba anya na Tianxiang, ụlọ ọrụ osisi okporo ụzọ China ama ama.

1) Cold Galvanizing (A na-akpọkwa electro-galvanizing): Mgbe a na-ekpochapụ na pickling, a na-etinye ígwè ahụ na ngwọta nnu zinc. A na-ejikọta ihe ngwọta ahụ na electrode na-adịghị mma nke ngwá ọrụ electrolysis, a na-etinyekwa efere zinc n'akụkụ nke ọzọ, jikọọ na electrode dị mma. Mgbe a na-agbanye ike, dị ka ihe dị ugbu a na-emegharị ntụziaka site na ihe dị mma gaa na electrode na-adịghị mma, akwa akwa akwa akwa, akwa na nke ọma jikọtara ya na-etolite n'elu ọkpọ ígwè.

2) Hot-mikpu galvanizing: Igwe nchara n'elu na-emikpu na zinc a wụrụ awụ na-eso ihicha na ịgbalite. Igwe zinc dara na-etolite n'elu igwe n'ihi mmeghachi omume physicochemical n'etiti ígwè na zinc na interface. E jiri ya tụnyere galvanizing oyi, usoro a na-emepụta njikọ siri ike n'etiti mkpuchi na mkpụrụ, na-eme ka njupụta mkpuchi dịkwuo mma, ịdịte aka, ọrụ na-enweghị mmezi, na ọnụ ahịa.

1) Usoro nhazi: Aha ha na-eme ka ọdịiche ahụ pụta ìhè. A na-eji Zinc enwetara na okpomọkụ dị n'ime ụlọ na ọkpọkọ ígwè na-ekpo ọkụ na-ekpo ọkụ, ebe a na-eji zinc enweta na 450 ° C ruo 480 Celsius C na-ekpo ọkụ na-ekpo ọkụ.

2) Mkpuchi mkpuchi: Ọ bụ ezie na galvanizing oyi na-atụ na-emekarị na-emepụta ihe mkpuchi mkpuchi nke naanị 3-5 μm, nke na-eme ka nhazi dị mfe karị, ọ na-enwe mmetụta na-adịghị mma. N'ụzọ dị iche, galvanizing na-ekpo ọkụ na-enyekarị mkpuchi mkpuchi nke 10μm ma ọ bụ karịa, nke bụ ọtụtụ iri ugboro karịa corrosion na-eguzogide ọgwụ karịa ogwe ọkụ galvanized oyi.

3) Ihe mkpuchi mkpuchi: A na-ekewa mkpuchi na mkpụrụ osisi site na oyi akwa ngwakọta na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ. Otú ọ dị, n'ihi na a na-emepụta ihe mkpuchi ahụ kpamkpam nke zinc, nke na-eme ka ihe mkpuchi na-ejikọta ya na obere pores, na-eme ka ọ ghara ịdị na-emerụ ahụ, nke a na-enwe mmetụta dị nta na iguzogide corrosion. N'ụzọ dị iche, galvanizing oyi na-atụ na-eji mkpuchi nke zinc atom na usoro adhesion anụ ahụ nwere ọtụtụ pores, nke na-eme ka ọ ghara imebi gburugburu ebe obibi.

4) Ọnụ ego dị iche iche: mmepụta nke galvanizing na-ekpo ọkụ na-esiwanye ike na mgbagwoju anya. Ya mere, obere ụlọ ọrụ nwere akụrụngwa ochie na-ejikarị galvanizing oyi na-atụ, na-ebute ọnụ ahịa dị ala nke ukwuu. Ndị na-emepụta galvanizing na-ekpo ọkụ na-ekpo ọkụ nke ukwuu, na-enwekarị njikwa mma, na-eduga na ọnụ ahịa dị elu.

Ụfọdụ ndị mmadụ nwere ike ịsị na ọ bụrụgodị na ha maara ihe dị iche n’etiti galvanizing oyi na-atụ n’ime mmiri na-ekpo ọkụ, na ha enweghị ike ịmata ọdịiche ahụ. Ndị a bụ ụzọ nhazi nke a na-adịghị ahụ anya na anya gba ọtọ. Gịnị ma ọ bụrụ na onye ahịa na-adịghị akwụwa aka ọtọ na-eji galvanizing oyi na-atụ kama iji mmiri na-ekpo ọkụ? N'ezie, ọ dịghị mkpa ichegbu onwe gị. Oyi-mikpu galvanizing nagalvanizing na-ekpo ọkụdị nnọọ mfe ịmata.

Ebe oyi na-atụ n'ime galvanized na-adịchaghị mma, ọkachasị na-acha odo odo-acha akwụkwọ ndụ akwụkwọ ndụ, mana ụfọdụ nwere ike ịdị na-acha aja aja, na-acha anụnụ anụnụ ma ọ bụ na-acha ọcha na-acha akwụkwọ ndụ akwụkwọ ndụ. Ha nwere ike ịpụta dị ntakịrị ma ọ bụ ruru unyi. Ebe ndị na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ, ma e jiri ya tụnyere ha, dị ntakịrị karịa, ma nwee ike inwe oge ntoju zinc, mana ha na-egbuke egbuke ma na-adịkarị ọcha. Lezienụ anya na ndịiche ndị a.
