Kev tsim kho

Fabmann tshwj xeeb hauv steel weldments, heavy duty brackets, connectors, wood post caps, heavy duty post support, signposts, tunnel brackets, heavy duty, steel piles, post support, heavy duty laj kab, heave duty plates, heavy dutykhoom kho vajtse nrog rau saum toj kawg nkauskub dip galvanizationzoo rau kev tsim kho tej yaam num hauv cheeb tsam Pacific thiab Atlantic. Daim ntawv thov kub-dip galvanizing (HDG) tsis yog tsuas yog kev txiav txim siab xwb, tab sis nws yog qhov kev xav tau zoo uas txhawb nqa cov ntsiab lus tseem ceeb ntawm kev pab txhim kho. Tag nrho cov haujlwm no muaj cov yam ntxwv zoo sib xws:

 

 

• √Lub neej ua haujlwm ntev

Tej yaam num feem ntau raug txiav txim los ntawm lub neej ua haujlwm ntev, tsis yog tus nqi pib siv xwb. Cov neeg cog lus feem ntau paub tias HDG tej zaum yuav muaj tus nqi siab dua me ntsis dua li qee cov xim pleev xim, tsis tau, nws lub neej 30-50+ xyoo nyob rau hauv feem ntau ib puag ncig nrog xoom tu muaj qhov zoo tshaj plaws tag nrho - ntawm - lub neej tus nqi. Qhov no yog ib qho tseem ceeb ntawm kev muag khoom rau kev siv lub luag haujlwm ntawm kev pab nyiaj. Hauv kev tsim kho vaj tse, xws li hauv qab hiav txwv tunnel lossis dej hiav txwv ntug dej hiav txwv, cov khoom siv kho vaj tse, cov khoom siv hlau, cov hlua khi yuav tsum tau galvanization thickness saum 115μm kom ua tiav cov kev pab cuam lub neej.

 

• √Kev nyab xeeb thiab Environmental Resilience

Ntau qhov dej num hauv Pacific thiab Atlantic yog nyob rau hauv ib puag ncig corrosive marine (ISO 12944 C4, C5-M, lossis CX). Cov av noo siab, khaus UV hluav taws xob, thiab ntsev- huab cua laden yuav sai sai hauv qab - cov hlau tiv thaiv. HDG muab lub zog, metallurgically bonded zinc txheej uas yog tus qauv kub rau kev tiv thaiv corrosion hauv cov xwm txheej no.

 

• √Txo Tus Nqi Kho Mob

Lub hom phiaj tseem ceeb ntawm kev txhim kho kom ruaj khov yog kom tsis txhob muaj lub nra hnyav rau lub teb chaws nrog cov nqi kho mob siab rau yav tom ntej lossis cov kev xav tau nyuaj. Ib qho "haum-thiab-tsis nco qab" kev daws teeb meem zoo li HDG ua kom muaj kev ncaj ncees ntawm cov qauv tsim, choj, lossis chaw nres nkoj rau ntau xyoo yam tsis tas yuav tsum muaj cov kws tshaj lij kho lossis kho, tso cov peev txheej hauv zos rau lwm qhov tseem ceeb.

 

• √Robustness rau Logistics

Ntau qhov kev tsim kho vaj tse hauv Pacific thiab Atlantic feem ntau cuam tshuam nrog kev thauj mus los yooj yim, nrog rau cov khoom raug xa tawm, tshem tawm, thiab ua haujlwm ntau zaus. Cov tawv tawv, abrasion-resistant xwm ntawm HDG txheej yog nyob deb npaum li resilient rau thauj thiab erection puas dua ib tug xim zaj duab xis.

 

Txhawm rau xa tawm raws li HDG cov lus qhia tshwj xeeb, Fabmann tuaj yeem muab cov ntaub ntawv tag nrho suav nrog cov hauv qab no:

 

A. Galvanizing Standard: Tsis yog -Tshaj tawm

Muaj ob peb tus qauv kub dip galvanization nyob rau hauv cov cheeb tsam sib txawv, thiab cov cheeb tsam sib txawv yuav hais rau lawv tus kheej tus qauv. Tab sis, hauv txoj cai, cov qauv no zoo sib xws. Txawm li cas los xij, tus neeg cog lus yuav xav tau ntau dua qhov tshwj xeeb tshaj li cov qauv qhia. Fabmann tuaj yeem muab rau cov qauv hauv qab no:

 

 

1. 1. ISO 1461: 2022: Kub dip galvanized coatings ntawm fabricated hlau thiab steel khoom - Specifications thiab xeem txoj kev. Cov qauv no tau lees paub los ntawm tag nrho EU thiab UK, thiab hauv Scandinavian Kev Lag Luam tshwj xeeb, cov neeg cog lus thiab cov neeg yuav khoom feem ntau xav tau cov zinc txheej tuab dua li txheej txheej txheej txheej txheem txheej txheem ISO1461.

1. 2. AS/NZS 4680: 2006: Kub-dip galvanized (zinc) coatings ntawm fabricated ferrous khoom, thiab tus qauv no muaj nyob rau hauv Australia, Solomon Islands, Tasmania, thiab New Zealand. Tag nrho cov txheej txheem steel ua haujlwm yuav tsum kub-dip galvanized tom qab fabrication nyob rau hauv tag nrho ua raws li ISO AS/NZS 4680:2006.
2.  
3. 3. ASTM A123 / A123M
4. Nws yog qhov tseem ceeb ntawm Kub-Dip Galvanization tus qauv hauv North American ntawm cov khoom siv hlau thiab hlau, suav nrog cov khoom steel ib leeg nrog rau kev sib dhos ntawm ntau chav kawm ntawm cov ntaub ntawv suav nrog cov qauv duab, sawb thiab bar, phaj, yeeb nkab thiab tubing, hlau, thiab cov khoom siv ntxiv.
5.  
6. 4. JIS H8641
7. Nws yog Japanese Kub Dip Galvanization Standard, thiab nws qhia meej txog qhov yuav tsum tau ua rau qhov zoo ntawm qhov tseem ceeb ntawm kub dip galvanized txheej siv rau cov khoom siv hlau, steel ua haujlwm, steel castings thiab forgings thiab hlau castings rau lub hom phiaj ntawm kev tiv thaiv corrosion. Nws tsis siv rau cov ntawv hlau, cov xaim hlau thiab cov hlau hlau uas tsis tu ncua kub dip galvanized, thiab tom qab - kho / dhau - txheej ntawm cov khoom kub dip galvanized.
8.  
9. 5. TIAB SA 13912
10. Nws yog Suav Kub Dip Galvanization Standard uas muaj feem xyuam nrog ISO 1461 nrog qee qhov kev hloov kho tsis ntev los no, thiab nws tau txhais tias yog xim hlau txheej -Kub Dip Galvanized Coatings ntawm Fabricated Ferrous Products.
11.  

Tag nrho cov qauv HDG no hais txog cov hauv qab no:

• √Txheej Thickness / Nyhav nyob ntawm seb cov khoom siv thiab cov thickness steel.
• √Finish zoo: nruam, du, uniform.
• √Qhov tshwm sim tsis muaj qhov tsis muaj coated, hlwv, flux deposits thiab gross dross inclusions nrog rau tsis muaj zinc deposits hnyav uas cuam tshuam rau kev siv.
• √Kev ua raws li tag nrho cov txheej txheem yuav tsum muaj kev ua tau zoo thoob plaws hauv lub neej kev pabcuam ntawm galvanized steel

 

B. Tsim rau Galvanizing

Kev tsim cov hlau ua haujlwm, txawm tias nws yog phaj, bracket, vuam, los yog raj vuam yuav tsum tsim nyog rau cov txheej txheem kub dip galvanization vim nws yog ib qho tseem ceeb los tiv thaiv qhov tsis xws luag. Hauv qab no yog qee cov hauv paus ntsiab lus.

 

• √Venting thiab Draining

Steelworks yuav tsum muaj qhov loj me thiab nyob hauv qhov kom tso cai rau cov zinc molten kom ntws tawm thiab tso cua kom dim. Qhov no tiv thaiv kev tawg nyob rau hauv zinc kettle thiab ua kom 100% txheej txheej.

• √Steel Chemistry (Tshuaj Chemistry ntawm Cov Hlau)

Cov ntsiab lus ntawm silicon thiab phosphorus ntawm cov hlautuaj yeem cuam tshuam cov txheej txheej zoo li thiab thickness. Txawm hais tias feem ntau cov qauv steels (piv txwv li, Qib 300, S235, S355) yog qhov tsim nyog, qhov no tuaj yeem yog qhov tseem ceeb yog tias cov khoom siv hlau los ntawm tsawg dua - kev lag luam tswj.

• √Vuam

Tag nrho cov vuam yuav tsum ua kom tiav ua ntej galvanizing, thiab tag nrho cov vuam slag yuav tsum tau muab tshem tawm kom huv si vim tias cov txheej txheem galvanizing yuav tsis npog nws.

 

C. Fasteners

Ntau cov hlau ua haujlwm siv cov fasteners rau kev sib dhos, thiab nws yog ib qho tseem ceeb heev los tiv thaiv galvanic corrosion (qhov twg cov hlau tsis tshua muaj zog corrodes nyiam), cov fasteners yuav tsum tau galvanized. Txhua lub bolts, txiv ntseej, thiab cov ntxhua khaub ncaws muaj cov qauv kub dip galvanization sib txawv vim lawv feem ntau siv cov tshuaj sib txawv xws li spinning galvanization (centrifuge galvanization). Hauv qab no yog cov npe ntawm cov qauv tseem ceeb rau HDG fasteners.

 

• √Teb chaws Europe, ISO1461
• √USA, ASTM A153 / A153M
• √Australia/New Zealand/Soloman Islands, AS/NZS 1214
• √Nyiv, JIS B1048
• √Tuam Tshoj, GBT 13912

 

Nws yog ib qho tsim nyog kom nkag siab tias HDG muaj qee yam cuam tshuam rau qhov haum ntawm cov fasteners vim zinc txheej ntxiv thickness rau cov xov, uas yuav ua rau muaj teeb meem haum. Yog li ntawd, qee tus neeg cog lus qhia tias cov txiv ntseej tau tapping oversize tom qab galvanizing kom ntseeg tau tias lawv yuav haum rau galvanized bolt threads. Ib qho kev ceeb toom ntxiv yog tias rau qee qhov muaj zog fasteners, cov tshuaj acid ua ntej - tsis tso cai vim nws yuav ua rau muaj teeb meem hydrogen embrittlement.

 

Txhawm rau xa cov khoom zoo siab kub dip galvanized workpiece, Fabmann siv cov txheej txheem nruj los ntawm cov khoom tsim los ntim & thauj khoom, thiab peb tswj hwm tag nrho kom paub tseeb tias peb cov neeg yuav khoom ib txwm tau txais yam lawv tau thov, thiab peb pab neeg saib xyuas cov hauv qab no tseem ceeb:
