Kusiyana pakati pa kuyika galvanizing kozizira ndi kuyika galvanizing kotentha pokonza mapaipi achitsulo

Kuthira Madzi Otentha Vs Kuthira Madzi Ozizira

Kupaka chitsulo ndi zinki pogwiritsa ntchito njira yotenthetsera ndi kuyika chitsulo ndi zinki kuti zisawonongeke, koma zimasiyana kwambiri ndi njira yogwirira ntchito, kulimba, komanso mtengo wake. Kupaka chitsulo ndi zinki pogwiritsa ntchito njira yotenthetsera ndi kuyika chitsulo mu chidebe chosungunuka cha zinki, zomwe zimapangitsa kuti chikhale cholimba komanso chogwirizana ndi mankhwala. Kupaka chitsulo ndi njira yophikira ndi zinki pogwiritsa ntchito njira yoziziritsira kapena kupaka utoto.

Pakukonza mapaipi achitsulo, kuyika ma galvanizing ndi njira yofunika kwambiri yowonjezerera kukana dzimbiri, yomwe imagawidwa m'njira ziwiri: kuyika ma galvanizing otentha (HDG) ndi kuyika ma galvanizing ozizira (Electro-Galvanizing, EG). Pali kusiyana kwakukulu pakati pa ziwirizi pankhani ya mfundo zoyendetsera, mawonekedwe a zokutira, ndi zochitika zomwe zingagwiritsidwe ntchito. Izi ndi kusanthula mwatsatanetsatane kuchokera ku miyeso ya njira zoyendetsera, mfundo, kuyerekeza magwiridwe antchito, ndi magawo ogwiritsira ntchito:

1. Kuyerekeza njira ndi mfundo zogwirira ntchito

1. Kutenthetsa ndi kuviika (HDG)

Njira Yopangira: Chitoliro chachitsulo chimamizidwa mu zinc wamadzimadzi osungunuka, ndipo zinc ndi chitsulo zimachitapo kanthu kuti zipange gawo la alloy.
Mfundo yopangira kupaka utoto:
Kugwirizana kwa zitsulo: Zinc yosungunuka imayanjana ndi matrix ya chitoliro chachitsulo kuti ipange gawo la Fe-Zn (Γ gawo Fe₃Zn₁₀, δ gawo FeZn₇, ndi zina zotero), ndipo gawo lakunja ndi gawo loyera la zinc.
2. Kukonza magetsi mozizira (electrogalvanizing, EG)
Njira Yopangira: Chitoliro chachitsulo chimamizidwa mu electrolyte yokhala ndi ayoni a zinc ngati cathode, ndipo wosanjikiza wa zinc umayikidwa ndi mphamvu yolunjika.
Mfundo yopangira kupaka utoto:
Kuyika kwa electrochemical: Ma ayoni a zinc (Zn²⁺) amachepetsedwa kukhala ma atomu a zinc ndi ma elekitironi pamwamba pa cathode (chitoliro chachitsulo) kuti apange chophimba chofanana (chopanda gawo la alloy).

2. Kusanthula Kusiyana kwa Njira

1. Kapangidwe ka zokutira

Kuviika ndi galvanizing yotentha:
Kapangidwe ka zigawo: gawo lapansi → Fe-Zn alloy layer → pure zinc layer. Alloy layer ili ndi kuuma kwakukulu ndipo imapereka chitetezo chowonjezera.
Kuzizira kokhala ndi ma galvanizing:
Zinc wosanjikiza umodzi, palibe kusintha kwa alloy, kosavuta kuyambitsa dzimbiri chifukwa cha kuwonongeka kwa makina.
 
2. Mayeso a kumatira
Kuthira ma galvanizing otentha: Pambuyo poyesa kupindika kapena kuyesa nyundo, chophimbacho sichimavuta kuchotsa (chosanjikiza cha alloy chimalumikizidwa mwamphamvu ku substrate).
Kuphimba kozizira: Chophimbacho chingagwe chifukwa cha mphamvu yakunja (monga "kuchotsa" pambuyo pokanda).
 
3. Njira yotsutsa dzimbiri
Kuviika ndi galvanizing yotentha:
Chitetezo cha anode ya nsembe + chotchinga: Zinc layer imawononga choyamba, ndipo alloy layer imachedwetsa kufalikira kwa dzimbiri ku substrate.
Kuzizira kokhala ndi ma galvanizing:
Amadalira kwambiri chitetezo cha zotchinga, ndipo gawo lapansi limakhala ndi dzimbiri pambuyo poti chophimbacho chawonongeka.

3. Kusankha njira yogwiritsira ntchito

3. Kusankha njira yogwiritsira ntchito

Zochitika zomwe zingagwiritsidwe ntchito pa mapaipi achitsulo opangidwa ndi galvanized otentha
Malo ovuta:nyumba zakunja (nsanja zotumizira, milatho), mapaipi apansi panthaka, malo ogwirira ntchito zapamadzi.
Zofunikira pa kulimba kwambiri:ma scaffolding a nyumba, zotchingira misewu.
 
Zochitika zomwe zingagwiritsidwe ntchito pa mapaipi achitsulo opangidwa ndi galvanized ozizira
Malo ofooka a dzimbiri:ngalande yamagetsi yamkati, chimango cha mipando, zida zamagalimoto.
Zofunikira zazikulu pakuoneka:nyumba ya zipangizo zapakhomo, mapaipi okongoletsera (pamwamba losalala ndi mtundu wofanana ndizofunikira).
Mapulojekiti ofunikira ndalama:malo ogwirira ntchito kwakanthawi, mapulojekiti omwe alibe bajeti yokwanira.
