ASTM A123 GI steel yeeb nkab

Tianjin Lefin Industrial Co., Ltd yog ib qho ntawm cov tuam ntxhab thiab cov muag khoom ntawm astm a123 gi steel yeeb nkab hauv Suav teb. Thov koj xav tias dawb mus yuav zoo astm a123 gi steel yeeb nkab los ntawm peb lub hoobkas. Kev pabcuam zoo thiab tus nqi tsim nyog muaj.

ASTM A123 yog tus qauv tseem ceeb rau kub-dip galvanized txheej ntawm cov khoom hlau, uas yog qhov tseem ceeb tshwj xeeb rau cov kav hlau galvanized. Cov lus hauv qab no tuaj yeem pab koj nkag siab cov ntsiab lus tseem ceeb ntawm ASTM A123 galvanized steel kav raws li cov qauv kev cai, cov yam ntxwv tshwj xeeb thiab cov ntawv thov tseem ceeb.

ASTM A123 tus qauv muaj cov kev cai meej thiab ntxaws ntxaws ntawm cov txheej txheem kub -dip galvanizing, txheej zoo, cov ntaub ntawv siv thiab kev sim.

• Txheej txheem thiab zinc txheej yam ntxwv:

Tus qauv yuav tsum tau siv cov txheej txheem kub -dip galvanizing. Cov txheej galvanized tsim tsis yog ib txheej zinc ntshiab, tab sis txheej txheej txheej txheej txheej txheej txheej txheej txheej ntawm Gamma txheej, Delta txheej, Zeta txheej thiab txheej txheej Eta sab nraud (ntshiab zinc txheej) ua tiav los ntawm lub hauv paus hlau mus rau sab nraud. Cov khaubncaws sab nraud povtseg no muaj cov ntsiab lus hlau sib txawv, thiab lawv cov hardness tseem siab dua li cov hlau hauv paus. Yog li ntawd, cov txheej yog hnav-resistant thiab muaj adhesion zoo. Tus qauv tseem xav kom cov ntsiab lus zinc nruab nrab ntawm cov hlau molten nyob rau hauv da dej galvanizing yuav tsum tsis pub tsawg tshaj 98% (los ntawm qhov hnyav feem pua), thiab tso cai rau ntxiv cov kab ntawm cov ntsiab lus xws li txhuas thiab npib tsib xee los txhim kho cov tsos thiab txheej txheem ntawm txheej.

• Zinc txheej thickness:

Tus txheej txheem qhia txog qhov nruab nrab qhov nruab nrab txheej txheej thickness raws li cov khoom siv (xws li cov qauv hlau, steel phaj, steel strips, tuav, steel kav, hlau rods, thiab lwm yam) thiab thickness ntawm cov hlau. Piv txwv li, rau "cov kav hlau thiab cov khoom siv yeeb nkab", qhov tsawg kawg nkaus qhov nruab nrab txheej tuab yuav tsum tau sib txawv nyob ntawm qhov tuab ntawm cov hlau, feem ntau yog li ntawm 45 microns txog 75 microns. Tus qauv kuj tseem muaj cov kev cai nruj ntawm kev coj mus kuaj, tus naj npawb ntawm cov ntsiab lus ntsuas (feem ntau tsis pub tsawg tshaj 5 cov ntsiab lus ntawm ib tus qauv), thiab suav cov nqi nruab nrab.

• Zoo thiab Kev Tshuaj Xyuas:

Lub galvanized txheej yuav tsum tsis tu ncua thiab sib xws. Me me roughness muaj feem xyuam rau cov tshuaj muaj pes tsawg leeg los yog cov tshuaj tiv thaiv ntawm lub hauv paus hlau yog tso cai, tab sis yuav tsum tsis txhob muaj teeb meem tsis zoo uas cuam tshuam rau kev siv. Cov txheej txheem kuj suav nrog cov kev cai thiab cov txheej txheem rau kev ua kom cov txheej txheej (xws li kev sim rauj) thiab kev kho cov txheej txheem tsis zoo (uas yuav tsum tau ua raws li A780 tus qauv, nrog rau thaj chaw kho tsis raug). Tus txheej txheem tau teev tseg tias cov khoom lag luam nrog thaj tsam thaj tsam ntau dua 160 square inches yuav tsum tau kuaj thiab kuaj hauv ntau thaj chaw.

Cov kav hlau galvanized ua raws li ASTM A123 tus qauv muaj cov hauv qab no qhov zoo:

• Zoo corrosion kuj thiab ntev - tiv thaiv ntev:

Qhov kub-dip galvanized txheej ua ntej ua lub cev tiv thaiv, cais cov hlau substrate los ntawm ib puag ncig corrosive. Qhov tseem ceeb tshaj, thaum txheej txheej puas lawm, zinc yuav ua raws li "sacrificial anode" thiab corrode nyiam, yog li tiv thaiv cov hlau sab hauv. Qhov kev tiv thaiv cathodic no tsis muaj nyob hauv ntau lwm cov txheej txheem. Tus nqi corrosion ntawm zinc txheej nyob rau hauv cov huab cua yog qeeb heev, kwv yees li 1/17 txog 1/18 ntawm cov hlau, uas muab galvanized steel kav rau lub neej ntev heev.

• Cov txheej txheem tiv thaiv zoo thiab muaj zog:

Cov txheej txheem kub -dip galvanizing ua rau cov kua zinc nkag mus rau txhua lub ces kaum ntawm cov yeeb nkab, txawm tias muab cov txheej txheem tiv thaiv zoo ib yam ntawm cov phab ntsa sab hauv thiab cov chaw so. Kev tiv thaiv kev ncaj ncees feem ntau zoo dua li ntawm phau ntawv pleev xim. Cov zinc- hlau alloy txheej tsim thaum lub sij hawm galvanizing txheej txheem muaj siab hardness thiab zoo hnav tsis kam.

• Ntsuas cov txiaj ntsig kev lag luam thiab kev ntseeg siab:

Txawm hais tias tus nqi pib yuav siab dua me ntsis, galvanized steel kav yuav luag tsis muaj kev saib xyuas thoob plaws hauv lawv lub neej ua haujlwm ntev, thiab tus nqi -kev ua tau zoo thoob plaws hauv lawv lub neej tag nrho yog qhov zoo kawg nkaus. Tsis tas li ntawd, kev kho galvanizing yog cov txheej txheem tswj kev ua tau zoo hauv cov chaw tsim khoom, thiab qhov zoo ntawm nws cov txheej yog txhim khu kev qha thiab ruaj khov.

ASTM A123 galvanized steel kav yog dav siv nyob rau hauv ntau yam tseem ceeb vim lawv zoo heev corrosion kuj thiab muaj zog durability.

• Architecture thiab Structure:

Feem ntau siv nyob rau hauv cov txheej txheem thav duab ntawm cov tsev, stair railings, txoj kev guardrails, scaffolding, thiab lwm yam. Nyob rau hauv cov ntaub ntawv no scenarios, steel kav yuav tsum tau raug rau cov huab cua ntev ntev, thiab zoo corrosion kuj yog ib qho tseem ceeb heev.

• Infrastructure thiab public utilities:

Feem ntau siv rau hauv cov kav dej (xws li cov kav dej), hluav taws xob tiv thaiv hluav taws xob, thiab cov kav dej tiv thaiv kab hauv hluav taws xob thiab kev sib txuas lus. Nws cov kev tiv thaiv corrosion ua kom muaj kev nyab xeeb ntawm cov khoom siv dej thiab kev ntseeg siab ntawm qhov system.

• Kev Lag Luam thiab Kev Ua Liaj Ua Teb:

Hauv kev lag luam roj thiab roj, nws tuaj yeem siv rau kev thauj cov roj thiab roj. Nyob rau hauv kev ua liaj ua teb, nws yog dav siv nyob rau hauv irrigation systems, lub moj khaum qauv ntawm tsev cog khoom sheds, thiab kev tsim ntawm kev ua liaj ua teb machinery.
