Bambanci tsakanin galvanizing mai tsoma sanyi da galvanizing mai tsoma zafi a cikin sarrafa bututun ƙarfe

Ruwan Zafi da Ruwan Sanyi

Gilashin da aka tsoma a cikin ruwan zafi da kuma gilashin da aka sanya a cikin ruwan sanyi duk hanyoyi ne na shafa ƙarfe da zinc don hana tsatsa, amma sun bambanta sosai a tsari, dorewa, da farashi. Gilashin da aka tsoma a cikin ruwan zafi ya ƙunshi tsoma ƙarfe a cikin ruwan zinc mai narkewa, yana samar da wani Layer na zinc mai ɗorewa, wanda aka haɗa shi da sinadarai. Gilashin da aka sanya a cikin ruwan sanyi, a gefe guda, tsari ne inda ake shafa fenti mai cike da zinc, sau da yawa ta hanyar fesawa ko fenti.

A fannin sarrafa bututun ƙarfe, yin amfani da galvanizing muhimmin tsari ne don inganta juriya ga tsatsa, wanda galibi aka raba shi zuwa hanyoyi biyu: yin amfani da galvanizing mai zafi (HDG) da kuma yin amfani da galvanizing mai sanyi (Electro-Galvanizing, EG). Akwai manyan bambance-bambance tsakanin su biyun dangane da ka'idojin sarrafawa, halayen shafa, da kuma yanayin da ya dace. Ga cikakken bayani daga girman hanyoyin sarrafawa, ƙa'idodi, kwatanta aiki, da filayen aikace-aikace:

1. Kwatanta hanyoyin sarrafawa da ƙa'idodi

1. Ruwan da ke tafasa a cikin ruwan zafi (HDG)

Tsarin Sarrafawa: Ana nutsar da bututun ƙarfe a cikin ruwan zinc mai narkewa, kuma zinc da ƙarfe suna amsawa don samar da layin ƙarfe.
Ka'idar samuwar shafi:
Haɗin ƙarfe: Zinc mai narkewa yana amsawa tare da matrix ɗin bututun ƙarfe don samar da Layer na Fe-Zn (Γ phase Fe₃Zn₁₀, δ phase FeZn₇, da sauransu), kuma Layer na waje shine Layer na zinc tsantsa.
2. Yin amfani da sinadarin galvanizing mai sanyi (electrogalvanizing, EG)
Tsarin sarrafawa: Ana nutsar da bututun ƙarfe a cikin wani electrolyte mai ɗauke da ions na zinc a matsayin cathode, kuma ana ajiye layin zinc ta hanyar wutar lantarki kai tsaye.
Ka'idar samuwar shafi:
Tacewar sinadaran lantarki: Ana rage ions na zinc (Zn²⁺) zuwa atom ɗin zinc ta hanyar electrons akan saman cathode (bututun ƙarfe) don samar da wani shafi iri ɗaya (ba tare da layin ƙarfe ba).

2. Binciken Bambancin Tsarin Aiki

1. Tsarin shafi

Galvanizing mai zafi:
Tsarin da aka yi wa layi: substrate → Layer na ƙarfe na Fe-Zn → Layer ɗin zinc mai tsarki. Layer ɗin ƙarfe yana da tauri mai yawa kuma yana ba da ƙarin kariya.
Gilashin sanyi:
Layer ɗin zinc guda ɗaya, babu canjin ƙarfe, mai sauƙin haifar da yaɗuwar tsatsa saboda lalacewar injiniya.
 
2. Gwajin mannewa
Galvanizing mai zafi: Bayan gwajin lanƙwasa ko gwajin guduma, murfin ba shi da sauƙin cirewa (ƙa'idar ƙarfe tana da alaƙa da substrate).
Yin amfani da galvanizing mai sanyi: Rufin na iya faɗuwa saboda ƙarfin waje (kamar abin da ke "barewa" bayan an goge shi).
 
3. Tsarin juriya ga tsatsa
Galvanizing mai zafi:
Kariyar shingen hadaya ta anode +: Layin zinc yana lalacewa da farko, kuma layin ƙarfe yana jinkirta yaɗuwar tsatsa zuwa ƙasa.
Gilashin sanyi:
Ya fi dogara ne akan kariyar shinge, kuma substrate ɗin yana iya yin tsatsa bayan an lalata murfin.

3. Zaɓin yanayin aikace-aikace

3. Zaɓin yanayin aikace-aikace

Yanayi masu dacewa don bututun ƙarfe na galvanized mai zafi
Muhalli masu wahala:gine-ginen waje (hasumiyoyin watsawa, gadoji), bututun karkashin kasa, wuraren aikin ruwa.
Bukatun dorewa masu girma:gina sifofi, shingen kariya na manyan hanyoyi.
 
Yanayi masu dacewa don bututun ƙarfe na galvanized da aka tsoma cikin sanyi
Yanayi mai laushi na lalata:bututun lantarki na cikin gida, firam ɗin kayan daki, sassan motoci.
Bukatun bayyanar da suka dace:wurin ajiye kayan gida, bututun ado (ana buƙatar saman da ya yi santsi da launi iri ɗaya).
Ayyukan da suka shafi farashi:kayan aiki na wucin gadi, ayyukan da ba su da kasafin kuɗi.
