3. Siv cov cuab yeej txiav thiab shaping los txiav thiab ua cov khoom rau qhov loj me.
4. Siv lub tshuab hluav taws xob siv hluav taws xob siv hluav taws xob los txuas cov txiav thiab tsim cov kav dej ua ke.
5. Cov yeeb nkab tau dhau los ua cov txheej txheem kho saum npoo kom tshem tawm cov impurities lossis deg tsis xws luag uas yuav cuam tshuam rau nws txoj haujlwm.
6. Txheej cov kav dej nrog ib txheej ntawm cov xim dub kom muab lawv cov yam ntxwv xim dub.
7. Cov yeeb nkab yog txiav mus rau qhov ntev thiab ntim
Daim ntawv thov:
1. Lub raj dub yog ua los ntawm cov hlau, uas muaj zog thiab ruaj khov thiab tsim nyog rau kev siv hauv kev lag luam. Cov yeeb nkab dub yog siv rau ntau yam kev lag luam, suav nrog roj thiab roj, cov kav dej thiab kev tsim kho.
2. Cov kav dej dub feem ntau yog siv hauv cov haujlwm tsim kho
3. Cov yam ntxwv tiv thaiv corrosion ua rau cov kav dej dub yog qhov kev xaiv zoo tshaj plaws rau kev thauj khoom thiab cov kua dej hauv cov huab cua phem.
qhov zoo:
1. Cov yeeb nkab dub yog ua los ntawm cov hlau, uas muaj zog thiab ruaj khov thiab tuaj yeem tiv taus qhov kub thiab txias. Nws yog qhov kev xaiv zoo tshaj plaws rau kev thauj khoom thiab cov kua dej hauv cov xwm txheej hnyav.
2. Ib qho txiaj ntsig ntawm kev siv cov kav dej dub yog qhov yooj yim rau nruab, txuag lub sijhawm thiab cov peev txheej tseem ceeb. Lawv kuj yog tus nqi tsim nyog, uas yog qhov tseem ceeb hauv kev tsim kho loj.
3. Lwm qhov zoo ntawm cov kav dej dub yog tias lawv muaj kev tiv thaiv corrosion thiab zoo heev rau kev siv hauv qhov chaw ntub dej.
GI cev:
Txheej txheem txheej txheem:
1. Thawj kauj ruam hauv GI PIPE txheej txheem yog xaiv cov khoom siv raw khoom zoo. Feem ntau, cov khoom siv raw ntawm GI PIPE yog cov pa roj carbon tsawg.
2. Ua ntau theem ntawm kev ua tiav ntawm cov raj xa dej nrog rau kev tu, kev kho ua ntej thiab txheej txheej.
3. Tom qab ntxuav, siv cov tshuaj pretreatment ntawm cov yeeb nkab los pab txhim kho cov adhesion ntawm galvanized txheej ntawm cov yeeb nkab nto.
4. Siv kub-dip galvanizing los yog electroplating rau hauv cov yeeb nkab rau hauv ib tug molten zinc da dej thiab coated nto nrog zinc tusyees.
5. Ua cov kev kuaj xyuas zoo ntawm cov kav dej thiab ua qhov kev ntsuam xyuas lub zog thiab kav ntev.
6. Cov yeeb nkab yog ces txiav mus rau qhov ntev thiab cov duab, npaj rau ntau yam kev siv.
qhov zoo:
1. Kev siv cov raj GI tsis tsuas yog ua kom yooj yim, tab sis kuj muaj kev cuam tshuam me ntsis rau ib puag ncig.
2. Cov zinc txheej ntawm GI kav dej muaj cov nyhuv tiv thaiv corrosion thiab tuaj yeem rov qab siv dua. Nrog rau kev saib xyuas cov kav dej kom zoo, nws tuaj yeem siv tau ntau xyoo, txo cov nqi lag luam.
3. Tsis tas li ntawd, scaffolding kuj muaj GI kav. Lawv yog lub teeb heev thiab yooj yim nqa.
Daim ntawv thov:
1. GI PIPE muaj ntau yam kev siv. GI kav tuaj yeem siv rau hauv kev tsim kho, kev ua liaj ua teb, thiab kev lag luam.
2. GI yeeb nkab yog cov khoom siv tseem ceeb rau qee qhov haujlwm tseem ceeb, xws li cov tsev loj, cov kav dej roj thiab roj, txuas hniav thiab cov kav dej hauv av.
3. Yog li ntawd, cov kav dej no tau siv dav hauv cov neeg niaj hnub no.
Qhov sib txawv ntawm cov yeeb nkab dub thiab GI yeeb nkab:
1. Kev ua cov txheej txheem sib txawv. Cov kav dej dub yog coated nrog cov xim dub los yog muab tso rau hauv cov tshuaj da dej uas muaj cov tshuaj pleev xim dub los tsim cov yeeb yaj kiab hlau oxide. Galvanized kav yog ua tiav los ntawm immersing steel kav hauv zinc kua.
2. Cov yeeb nkab dub yog pheej yig dua GI yeeb nkab raws li cov zinc txheej ntxiv rau tus nqi. GI yeeb nkab siv cov kub dip galvanized ua, nws ua rau tus nqi siab dua Dub yeeb nkab. Tus nqi yuav raug txo qis, tab sis kev ua haujlwm ntev thiab kev pabcuam lub neej ntawm GI kav dej zoo dua li cov kav dej dub.
3. Daim ntawv thov sib txawv. Cov kav dej Galvanized feem ntau yog siv rau kev thauj mus los hauv dej, thiab cov kav dej dub yog siv rau kev thauj mus los roj.
Cov yeeb nkab dub thiab cov yeeb nkab galvanized yog ob qho tib si dav siv, tab sis muaj ntau qhov sib txawv. Koj tuaj yeem xaiv cov khoom raws li koj xav tau.
