Nws yog qhov paub zoo tias qhov zoo ntawmgalvanized square thiab rectangular rajthiab txoj kev teeb tsa ncaj qha cuam tshuam rau kev ruaj khov ntawm cov qauv hlau.
Tam sim no, cov ntaub ntawv txhawb nqa hauv khw feem ntau yog cov hlau carbon. Cov khoom siv raw ntawm cov hlau carbon feem ntau yog Q235 thiab Q345, uas tau kho los ntawm kev kub galvanizing. Cov kev txhawb nqa yog ua los ntawm cov hlau strip los ntawm kev khoov txias, vuam, kub galvanizing thiab lwm yam txheej txheem. Feem ntau, qhov tuab yuav tsum ntau dua 2 hli, thiab tshwj xeeb tshaj yog rau qee qhov ntug dej hiav txwv, siab thiab lwm qhov chaw cua thiab thaj chaw, nws raug pom zoo tias qhov tuab yuav tsum tsis pub tsawg dua 2.5 hli, txwv tsis pub muaj kev pheej hmoo ntawm kev rhuav tshem ntawm qhov chaw txuas hlau.
Hauv cov tsev loj, rauCov yeeb nkab carbon steel galvanized square thiab rectangular, yuav tsum tau ua kom tuab npaum li cas ntawm cov zinc txheej kom ua tau raws li qhov yuav tsum tau ua ntawm kev tiv thaiv xeb ib puag ncig?
Raws li peb txhua tus paub, qhov tuab ntawm kub-dip galvanizing yog qhov tseem ceeb zoo thiab kev ntsuas kev ua haujlwm ntawmgalvanized square yeeb nkab, uas muaj feem cuam tshuam nrog kev nyab xeeb thiab kev ruaj khov ntawm cov qauv. Txawm hais tias muaj cov qauv hauv tebchaws thiab kev tshaj lij, qhov tuab ntawm zinc txheej tsis tsim nyog ntawm kev txhawb nqa tseem yog qhov teeb meem dav dav ntawm kev txhawb nqa.
Cov txheej txheem galvanizing kub-dip yog ib txoj kev kho mob saum npoo hlau uas ruaj khov thiab txhim khu kev qha los tiv thaiv kev xeb ib puag ncig. Muaj ntau yam uas cuam tshuam rau kev kub-dip galvanizing, xws li cov khoom sib xyaw ntawm cov hlau substrate, lub xeev sab nraud (xws li roughness), kev ntxhov siab sab hauv ntawm cov substrate, thiab ntau qhov ntau thiab tsawg. Thaum lub sijhawm no, qhov tuab ntawm cov substrate muaj kev cuam tshuam ntau dua rau qhov tuab ntawm kev kub-dip galvanizing. Feem ntau, qhov tuab ntawm lub phaj yog, qhov tuab ntawm kev kub-dip galvanizing ntau dua. Kev txhawb nqa nrog tuab ntawm 2.0 hli yog coj los ua piv txwv los qhia tias yuav tsum muaj pes tsawg tuab ntawm zinc txheej kom ua tiav qhov kev xav tau ntawm kev xeb ib puag ncig.
Xav tias qhov tuab ntawm cov khoom siv txhawb nqa yog 2 hli, raws li tus qauv GBT13192-2002 kub galvanizing tus qauv.
Yuav tsum muaj qhov tuab ntawm cov yeeb nkab galvanized square uas yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua haujlwm ntev npaum li cas?
Galvanized square yeeb nkab
Raws li qhov yuav tsum tau ua ntawm tus qauv hauv tebchaws, qhov tuab ntawm 2 hli cov khoom siv hauv paus yuav tsum tsis pub tsawg dua 45 μ m. Qhov tuab sib xws yuav tsum tsis pub tsawg dua 55 μ m. Raws li cov txiaj ntsig ntawm kev sim huab cua uas tau ua los ntawm Japanese Hot Dip Galvanizing Association txij li xyoo 1964 txog 1974. Qhov tuab ntawm cov yeeb nkab galvanized square uas yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm lub neej ua haujlwm yog dab tsi?
Yog xam raws li tus qauv hauv tebchaws, cov ntsiab lus zinc yog 55x7.2 = 396g / m2,
Lub neej ua haujlwm muaj nyob rau hauv plaub qhov chaw sib txawv yog hais txog:
Thaj chaw muaj kev lag luam hnyav: 8.91 xyoo, nrog rau qib xeb txhua xyoo ntawm 40.1;
Thaj chaw ntug dej hiav txwv: 32.67 xyoo, nrog rau qib xeb txhua xyoo ntawm 10.8;
Sab nraum zoov: 66.33 xyoo, nrog rau qib xeb txhua xyoo ntawm 5.4;
Thaj chaw hauv nroog: 20.79 xyoo, nrog rau qib xeb txhua xyoo ntawm 17.5
Yog xam raws li lub neej ua haujlwm ntawm lub photovoltaic ntawm 25 xyoo
Tom qab ntawd qhov sib lawv liag ntawm plaub thaj chaw yog tsawg kawg yog:
1002.5270135437.5, ie 139 μ m, 37.5 μ m, 18.75 μ m, 60.76 μ m.
Yog li ntawd, rau kev faib cov cheeb tsam hauv nroog, qhov tuab ntawm zinc txheej yuav tsum yog tsawg kawg 65 μ M yog qhov tsim nyog thiab tsim nyog, tab sis rau cov chaw lag luam hnyav, tshwj xeeb tshaj yog cov uas muaj acid thiab alkali corrosion, nws raug pom zoo tias qhov tuab ntawm galvanized square yeeb nkab thiab zinc txheej yuav tsum tau ntxiv kom raug.
