Musiyano uripo pakati pekudzikisa nekupisa (cold-dip galvanizing) nekudzikisa nekupisa (hot-dip galvanizing) mukugadzirisa mapaipi esimbi

Kupisa Dip Vs Kutonhora Dip Galvanizing

Kuisa galvanizing inopisa uye kuisa galvanizing inotonhora inzira mbiri dzekuisa simbi ne zinc kudzivirira ngura, asi dzakasiyana zvakanyanya mukushanda, kugara kwenguva refu, uye mutengo. Kuisa galvanizing inopisa kunosanganisira kunyudza simbi mubhavhu rakanyungudutswa re zinc, zvichigadzira zinc layer yakasimba, ine makemikari akabatana. Kuisa galvanizing inotonhora, kune rumwe rutivi, inzira iyo jira rine zinc yakawanda rinoiswa, kazhinji nekupfapfaidza kana kupenda.

Mukugadzirisa mapaipi esimbi, kugadzira magaroni inzira inokosha yekuvandudza kuramba kwengura, iyo inonyanya kukamurwa kuita nzira mbiri: kupisa-kudivha galvanizing (HDG) uye kutonhora galvanizing (Electro-Galvanizing, EG). Pane misiyano yakakura pakati pezviviri maererano nemisimboti yekugadzirisa, hunhu hwekuputira, uye mamiriro ezvinhu anoshanda. Inotevera ongororo yakadzama kubva pahukuru hwenzira dzekugadzirisa, misimboti, kuenzanisa mashandiro, uye minda yekushandisa:

1. Kuenzanisa nzira dzekugadzirisa uye misimboti

1. Kupisa-kunyika galvanizing (HDG)

Maitiro ekugadzirisa: Pombi yesimbi inonyudzwa mumvura yakanyungudutswa yezinc, uye zinc nesimbi zvinobatana kuti zvigadzire chikamu che alloy.
Pfungwa yekuumbwa kwependi:
Kubatana kwesimbi: Zinc yakanyungudutswa inosangana nesimbi yesimbi kuti igadzire Fe-Zn layer (Γ phase Fe₃Zn₁₀, δ phase FeZn₇, nezvimwewo), uye layer yekunze ilayer yezinc yakachena.
2. Kuisa simbi mumhepo inotonhora (electrogalvanizing, EG)
Maitiro ekugadzirisa: Pombi yesimbi inonyudzwa mu electrolyte ine zinc ions se cathode, uye zinc layer inoiswa ne direct current.
Pfungwa yekuumbwa kwependi:
Kuiswa kwemakemikari emagetsi: Maion ezinc (Zn²⁺) anoderedzwa kuita maatomu ezinc nemaerekitironi ari pamusoro pe cathode (simbi yepombi) kuti agadzire chifukidziro chakafanana (isina alloy layer).

2. Kuongorora Kusiyana Kwemaitiro

1. Chimiro chekunamira

Kupisa-kunyika:
Maumbirwo akarongwa: substrate → Fe-Zn alloy layer → pure zinc layer. Alloy layer ine kuoma kwakanyanya uye inopa dziviriro yakawedzerwa.
Kugadzirisa madziro kunotonhora:
Zinc layer imwe chete, hapana shanduko ye alloy, zviri nyore kukonzera ngura kupararira nekuda kwekukuvadzwa kwemakanika.
 
2. Bvunzo rekunamatira
Kupisa-kunyika galvanizing: Mushure mekukombama bvunzo kana bvunzo yehammer, coating yacho haisi nyore kubvisa (chikamu chealloy chakabatana zvakasimba ne substrate).
Kuvhara simbi nechando: Kuvhara simbi kunogona kudonha nekuda kwesimba rekunze (sekunge "kubvisa ganda" mushure mekukwenya).
 
3. Nzira yekudzivirira ngura
Kupisa-kunyika:
Dziviriro yeanode yechibayiro + chipingamupinyi: Zinc layer inotanga yaora, uye alloy layer inononoka kupararira kwengura kusubstrate.
Kugadzirisa madziro kunotonhora:
Inonyanya kuvimba nekuchengetedzwa kwezvidziviriro, uye substrate inogona kukuvadzwa kana chifukidziro chakuvara.

3. Sarudzo yemamiriro ekushandisa

3. Sarudzo yemamiriro ekushandisa

Mamiriro ezvinhu anoshanda pamapombi esimbi anopisa-kunyudza
Nzvimbo dzakaoma:zvivakwa zvekunze (shongwe dzekufambisa, mabhiriji), mapaipi epasi pevhu, zvivakwa zvemugungwa.
Zvinodiwa zvekugara kwenguva refu:zvivakwa zvekuvaka, zvidziviriro zvemigwagwa mikuru.
 
Mamiriro ezvinhu anoshanda pamapombi esimbi akavharidzirwa anotonhora
Nzvimbo ine ngura isina kusimba:mugero wemagetsi wemukati, furemu yefenicha, zvikamu zvemotokari.
Zvinodiwa pakuonekwa kwepamusoro:imba yemidziyo yepamba, mapaipi ekushongedza (nzvimbo yakatsetseka uye ruvara rwakafanana zvinodiwa).
Mapurojekiti anonyanya kukosha:zvivakwa zvenguva pfupi, mapurojekiti asina bhajeti rakawanda.
