Qhov Zoo
Highlighting zoo ntawm JIS G3444 Cov Kav Dej Hlau
Cov khoom siv zoo dua thiab ua kev ua haujlwm
JIS G3444 cov yeeb nkab steel yog ua los ntawm cov pa roj carbon hlau (xws li STKM11A, thiab lwm yam), uas muaj cov khoom siv tsawg tus nqi thiab yooj yim rau cov txheej txheem. Nws txoj kev vuam kev ua tau zoo heev, haum rau kev tsim qauv vuam loj.
Cov Khoom Ruaj Ntseg Ruaj Ntseg
Tus qauv muaj cov kev xav tau meej rau lub zog tensile, kom muaj zog ntawm cov yeeb nkab steel (xws li sib npaug ntawm 310 MPA), uas tuaj yeem ua tau raws li cov kev coj ua cov kab ke.
Moderate corrosion tsis kam
Los ntawm Galvanized lossis coated carbon hlau nto kev kho mob, tuaj yeem txhim kho cov kev tiv thaiv kev tiv thaiv corrosion, haum rau ib puag ncig kev lag luam.
Siab sab downensional qhov tseeb
JIS cov qauv nruj me ntsis txoj kab uas hla thiab phab ntsa thickness kam rau ntawm cov yeeb nkab steel (xws li txheej txheem sab nraud (xws li txheej txheem sab nraud (xws li cov hlab txheej loj (xws li 5%) kom ntseeg tau qhov tseeb.
Cov Ntawv Pov Thawj Saib Xyuas Feem Ntau
JIS G3444 cov yeeb nkab steel yog siv tau hauv cov teb hauv qab no:
1Cov. Lub Tsev Cov Qauv: Kev pab txhawb ib ntus lossis kev txhawb nqa ruaj khov xws li cov hlau yees, scaffolding, praffolding, thiab lwm yam.
2. Nplua: Lub Hauv Paus pawg, tsis-swb pawg, kev pheej choj, thiab lwm yam.
3. Muaj Cov Cuab Yeej Siv: Yooj yim tshuab thav duab, xa hluav taws xob txhawb thiab lwm yam xwm txheej tsis yog-siab siab siab.
Ceev faj rau kev cia, siv, thiab txij nkawm
Kev mloog zoo
1. Chaw cia khoom
• Zam kev muab tso rau hauv qhov qhib kom tsis txhob xeb los ntawm cov nag thiab huab cua nyab; Rau lub sijhawm ntev cia, nws pom zoo kom lub tsho tiv thaiv roj los yog siv galvanized steel kav kav.
• Cov yeeb nkab steel yuav tsum muab tso rau hauv lub tsev rau khoom qhuav thiab muaj qhov muag kom tsis txhob sib cuag nrog cov tshuaj xeb uas muaj kua qaub thiab alkali.
2. Kev Pab Cuam Tshuam
• Thaum vuam, nws yog qhov tsim nyog los ntxuav cov olide saum npoo los xyuas kom muaj qhov zoo ntawm Weld thiab zam lub zog txo los ntawm kev tsis txaus siab los ntawm impurities.
• Zam kev siv ntau dhau, tshwj xeeb yog them nyiaj rau qhov kev cuam tshuam txuas ntxiv thauj ntawm lub raj raj puas.
3. Txheeb xyuas txij nkawm
• Txheeb xyuas cov npoo npoo ib ntus, thiab hloov nws lub sijhawm thaum lub qhov tob corrosion ntau tshaj 10% ntawm phab ntsa tuab.
• Tsom rau kev tshuaj ntsuam ntawm cov ntaub ntawv vuam thiab cov pob qij txha los tiv thaiv cov kab nrib pleb muaj kev ntxhov siab.
