Hauv kev sib ntaus sib tua ntev tiv thaiv corrosion, kub-dip galvanized steel tau dhau los ua cov khoom siv hauv kev tsim kho, kev tsim vaj tsev, thiab kev tsim khoom lag luam vim nws cov khoom tiv thaiv zoo heev. Nws tsis yog txheej txheej nkaus xwb tab sis ntev - kev tiv thaiv kev tiv thaiv ntev tsim los ntawm cov tshuaj tiv thaiv metallurgical.
1. Core Technology: Kev tiv thaiv zoo heev los ntawm Metallurgical Bonding
Kub-dip galvanizing tsis yog txheej txheem txheej txheem lub cev yooj yim tab sis cov txheej txheem metallurgical nruj. Tom qab ntxuav, cov hlau seem yog immersed nyob rau hauv molten zinc ntawm kwv yees li 450 degree. Cov hlau substrate reacts nrog zinc los tsim ib qho tshwj xeeb stepwise zinc- hlau alloy txheej, uas yog thaum kawg them los ntawm ib txheej ntawm zinc ntshiab.
Txoj kev no endows nws nrog incomparable zoo:
- Kev Tiv Thaiv Cathodic: Txawm hais tias cov txheej hauv zos raug khawb vim khawb, zinc yuav ua raws li kev txi anode thiab corrode nyiam, tsis tu ncua tiv thaiv cov hlau substrate.
- Barrier Protection: The dense alloy layer and surface layer can effectively isolate contact with moisture, oxygen, and corrosive media.
- Self-healing: The dense basic zinc carbonate film generated by zinc during corrosion can further slow down the corrosion rate.
2. Kev Ua Tau Zoo: Cov ntaub ntawv thiab qhov tseeb
Piv nrog rau cov tshuaj tsuag zoo tib yam lossis electroplating, kub -dip galvanizing ua tau zoo nyob rau hauv ntev - lub sij hawm durability:
| Sib piv Dimensions | Kub-dip galvanizing | Ordinary xeb tiv thaiv xim |
| Lub neej expectancy | Muaj peev xwm kav ntev tshaj 50 xyoo nyob rau hauv ib puag ncig atmospheric | Feem ntau 5-10 xyoo, xav tau kev saib xyuas tsis tu ncua |
| Txheej adhesion | Metallurgical bonding, tsis yooj yim rau tev tawm | Lub cev adhesion, muaj kev puas tsuaj los ntawm kev cuam tshuam |
| Tus nqi tu | Tsawg heev nyob rau hauv tag nrho lub neej voj voog, pib txij nkawm- dawb | Xav tau kev tshuaj xyuas raws sij hawm thiab repainting |
| Kev tiv thaiv tsis sib xws | Muaj peev xwm npog tag nrho sab hauv thiab sab nrauv ntawm cov khoom siv | Kev pov hwm tsis zoo yog qhov tshwm sim ntawm cov npoo thiab qhov khoob. |
3. Cov ntawv thov tseem ceeb
Qhov no ntev - cov cuab yeej kav ntev ua rau nws tsim nyog tshwj xeeb rau cov xwm txheej uas nyuaj rau kev tswj hwm lossis qhov uas tsis ua haujlwm muaj qhov tshwm sim loj:
- Public infrastructure: kev loj guardrails, teeb pom kev zoo ncej, hluav taws xob xa mus yees, choj Cheebtsam. Cov chaw no raug rau sab nraum zoov, muaj cov nqi kho mob siab, thiab xav tau cov qauv kev nyab xeeb siab heev.
- Kev tsim kho thiab kev tsim: loj Hoobkas steel qauv, warehouse thav duab, lub tsev 外围护 systems. Lub zinc txheej muab kev ruaj ntseg lav rau tag nrho cov kev pab cuam lub neej ntawm lub tsev.
- Cov khoom siv: cable tais, kav dej, kev sib txuas lus yees. Galvanization tuaj yeem tiv thaiv txoj kev xeb hauv av thiab cua.
- Kev ua liaj ua teb thiab kev thauj mus los: cov khoom siv ua liaj ua teb, cov thawv ntim khoom fittings, tsheb chassis. Cov cuab yeej no feem ntau raug rau qhov chaw ntub dej thiab cov tshuaj uas ua rau kom muaj corrosion.
4. Cov ntsiab lus tseem ceeb los ua kom muaj kev ua haujlwm ntev -
Txhawm rau kom ua tiav nws lub peev xwm, kev saib xyuas yuav tsum tau them rau cov ntsiab lus hauv qab no thaum tsim khoom thiab xaiv:
- Base Material Pre-kev kho mob: Kev kho kom zoo thiab ua kom lub cev qhuav dej yog lub hauv paus rau kev tsim cov txheej txheem zoo, cuam tshuam ncaj qha rau adhesion thiab kev pabcuam lub neej.
- Zinc Txheej Thickness Control: Raws li kev siv ib puag ncig (xws li C2 hauv av huab cua mus rau C5 kev lag luam / dej hiav txwv ib puag ncig), ua raws li cov qauv zoo li ISO 1461 los xaiv qhov tsim nyog tsawg kawg nkaus zinc txheej tuab.
- Ncej -Kev Ua Haujlwm (Yeem): Rau kev zoo nkauj dua lossis cov xim tshwj xeeb, kev siv tshuaj lom neeg lossis cov txheej txheem sib xyaw (xws li 'galvanization + hmoov txheej') tuaj yeem ua tiav kom ua tiav ob qho kev txhim kho hauv kev tiv thaiv thiab kev zoo nkauj.
