Nws yog paub zoo tias qhov zoo ntawmgalvanized square thiab rectangular rajthiab txoj kev teeb tsa ncaj qha cuam tshuam rau kev ruaj ntseg ntawm cov qauv steel.
Tam sim no, cov ntaub ntawv txhawb nqa ntawm kev ua lag luam feem ntau yog carbon steel. Cov khoom siv raw ntawm carbon steel feem ntau yog Q235 thiab Q345, uas tau kho los ntawm kub galvanizing. Kev them nyiaj yug yog ua los ntawm sawb steel kauj los ntawm kev khoov txias, vuam, kub galvanizing thiab lwm yam txheej txheem. Feem ntau, lub thickness yuav tsum siab tshaj 2 hli, thiab tshwj xeeb tshaj yog rau tej ntug hiav txwv dej, siab-nce thiab lwm yam cua thiab tej cheeb tsam, nws yog pom zoo kom lub thickness yuav tsum tsis txhob tsawg tshaj li 2.5 hli, txwv tsis pub muaj kev pheej hmoo ntawm tearing ntawm cov hlau. kev sib txuas point.
Hauv cov tsev loj loj, raucarbon steel galvanized square thiab rectangular kav, ntau npaum li cas thickness ntawm zinc txheej yuav tsum tau mus txog raws li qhov yuav tsum tau ntawm ib puag ncig corrosion kev pab cuam lub neej?
Raws li peb txhua tus paub, lub thickness ntawm kub-dip galvanizing yog ib qho tseem ceeb zoo thiab kev Performance index ntawmgalvanized square yeeb nkab, uas muaj feem xyuam rau kev nyab xeeb thiab kav ntev ntawm cov qauv. Txawm hais tias muaj cov qauv hauv tebchaws thiab kev tshaj lij, qhov tsis tsim nyog zinc txheej thickness ntawm kev txhawb nqa tseem yog ib qho teeb meem ntawm kev txhawb nqa.
Cov txheej txheem kub-dip galvanizing yog qhov ruaj khov thiab txhim khu kev qha steel nto kev kho mob los tiv thaiv ib puag ncig corrosion. Muaj ntau yam uas cuam tshuam rau kub-dip galvanizing, xws li cov khoom ntawm cov hlau substrate, lub xeev sab nraud (xws li roughness), kev ntxhov siab sab hauv ntawm lub substrate, thiab ntau qhov ntau thiab tsawg. Thaum lub sij hawm tus txheej txheem no, lub thickness ntawm lub substrate muaj feem xyuam rau lub thickness ntawm kub-dip galvanizing. Feem ntau, lub phaj tuab dua, qhov tuab ntawm qhov kub-dip galvanizing ntau dua. Kev them nyiaj yug nrog tuab ntawm 2.0mm yog coj los ua piv txwv los piav qhia seb yuav tsum muaj zinc txheej tuab npaum li cas los ua kom tau raws li qhov xav tau ntawm ib puag ncig corrosion.
Xav tias qhov tuab ntawm cov khoom siv hauv paus yog 2 hli, raws li tus qauv GBT13192-2002 kub galvanizing tus qauv.
Dab tsi yog qhov tuab ntawm galvanized txheej ntawm galvanized square yeeb nkab yuav tsum tau ua kom tau raws li qhov kev pab cuam lub neej?
Galvanized square yeeb nkab
Raws li cov kev cai ntawm lub teb chaws tus qauv, lub thickness ntawm 2 hli puag khoom yuav tsum tsis txhob yuav tsawg tshaj li 45 μ m. Cov tuab tuab yuav tsum tsis pub tsawg dua 55 μ m. Raws li cov txiaj ntsig ntawm atmospheric exposure test ua los ntawm Japanese Hot Dip Galvanizing Association los ntawm 1964 txog 1974. Dab tsi yog qhov thickness ntawm galvanized txheej ntawm galvanized square yeeb nkab yuav tsum tau ua kom tau raws li qhov kev pab cuam lub neej. ?
Yog hais tias xam raws li lub teb chaws tus qauv, cov ntsiab lus zinc yog 55x7.2 = 396g / m2,
Lub neej kev pabcuam muaj nyob rau hauv plaub qhov chaw sib txawv yog hais txog:
Heavy industrial tsam: 8.91 xyoo, nrog rau txhua xyoo corrosion degree ntawm 40.1;
Thaj tsam ntug dej hiav txwv: 32.67 xyoo, nrog rau txhua xyoo corrosion degree ntawm 10.8;
Sab nrauv: 66.33 xyoo, nrog rau txhua xyoo corrosion degree ntawm 5.4;
Lub nroog cheeb tsam: 20.79 xyoo, nrog rau txhua xyoo corrosion degree ntawm 17.5
Yog xam raws li photovoltaic kev pab cuam lub neej ntawm 25 xyoo
Tom qab ntawd qhov sib lawv liag ntawm plaub thaj tsam 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, lub thickness ntawm zinc txheej yuav tsum yog tsawg kawg 65 μ M yog tsim nyog thiab tsim nyog, tab sis rau hnyav industrial cheeb tsam, tshwj xeeb tshaj yog cov acid thiab alkali corrosion, nws yog pom zoo kom lub thickness ntawm galvanized square yeeb nkab. thiab zinc txheej yuav tsum tau muab ntxiv kom zoo.
