1.What yog cov khoom siv tshuab ntawm Q345B Galvanized Chev?
High - Cov Kab Mob Muaj Zog: Tawm Zog}}}}}}, Q235MPA). Nws tuaj yeem tiv thaiv hnyav thiab haum rau kev tsim khoom-cov kabmob sib xyaw ua ke (xws li cov hlua hlau sib txuas).
Zoo heev qis - kub tawv: Cov qib qis "B" yuav tsum muaj kev cuam tshuam loj dua los yog sib npaug nrog kev ntsuas ntawm 20 degree. Nws yog resistant rau nkig tawg ntawm tsawg kub thiab yog qhov tsim nyog rau kev ua si sab nraum zoov hauv cov khoom kub sab nrauv lossis cov tsev sab nrauv (xws li lub tsev sab nrauv sab nrauv.
Cov khoom siv hluav taws xob ruaj khov: Cov khoom siv hauv paus yog feem ntau ua rau siv cov txheej txheem txuas ntxiv (suav nrog kev pheej hmoo ntawm kev sib txawv los ntawm kev sib txawv hauv zos.
2.What yog lub corrosion tsis kam ntawm Q345B Galvanized Chev?
Kub - dip galvanizing (cov txheej txheem tseem ceeb):
Lub galvangized txheej tuab yog li 50 - 100μm (kho tau raws li cov cai). Cov txheej zinc txheej "zinc-hlau alloy txheej" nrog rau substrate "nrog rau lub substrate, muab lub zog ua kom muaj zog dua lossis sib npaug ntawm 90n / hli) thiab tawm tsam peeting.
Lub hauv paus ntsiab lus yog "kev tiv thaiv Anodic": Zinc muaj qhov qis dua electrode peev xwm tshaj li hlau. Thaum cov steel saum npoo yog puas, zinc corrodes nyiam, tiv thaiv lub substrate los ntawm xeb. Nyob rau hauv ib puag ncig ib puag ncig (tsis muaj cov kua qaub sab nraum zoov lossis alkalis), cov kev pabcuam lub neej tuaj yeem ncav cuag 15-5 xyoos (piv rau 3-5 xyoos rau cov qauv Q345B).
Electrogalvanizing (Precision Daim Ntawv Thov):
Cov txheej zinc txheej yog thinner (5 -}}}} 20μm), tab sis muaj smoother saum npoo thiab siab dua. Nws corrosion tsis kam yog qis dua li ntawd ntawm kub-dip galvanizing, ua rau nws haum rau sab hauv tsev (xws li tsev siv khoom vaj tse).
Huab cua Kuj: Nws tuaj yeem tiv taus vaum thiab me ntsis saline {{0} {alkali ib puag ncig (xws li luv} lub sij hawm pos huab nyob rau hauv ntug hiav txwv cheeb tsam). Txawm li cas los xij, ntev -}} Todle raug rau cov kua qaub muaj zog (xws li cov kua roj hmab) tseem yuav tsum muaj kev tiv thaiv.
3.Qhov yog kev ua haujlwm ntawm Q345B Galvanized Chev?
Cuttability: nws tuaj yeem siv cov shearing, laser txiav, yog li tsis muaj cov txheej txheem ntawm cov khoom siv "tawv tawv dawb"}
Bendability: nws nthuav tawm cov khoom txias zoo heev thiab tuaj yeem bent 90 degree, rau thicknesses tau muaj tsawg dua lossis sib npaug rau 2 zaug lub phaj tuab). Nws tsis yog qhov ua tau tawg thiab yog tsim rau kev tsim cov txheej txheem nkhaus (xws li cov yeeb nkab txhawb nqa thiab lub log tsheb npog npog).
Weldability: nws ua rau cov muaj kev siv zog zoo siab rau siab kom muaj siab siv cov hlau vuam hlau vuam lossis xws li co₂ vuam). Weld lub zog tuaj yeem ncav cuag ntau dua 80% ntawm cov khoom siv hauv paus lub zog, tsis tas yuav tsum tau them rau kev tswj hwm cua sov thaum tshav kub kub kom tsis txhob muaj kev cuam tshuam). Stamping Lub Gravabic: Nyias- Cov khoom lag luam uas muaj zog (xws li Quaj Quav Galvanized)
4.What yog cov tsos thiab siv tau ruaj khov ntawm Q345B Galvanized Chev?
Kev du nto: Galvanizing feem ntau undergoes ib qho kev kho smoothing, ua rau muaj qhov chaw dawb ntawm pitting thiab zinc cov lus. Kub {- dip galvanized coils muaj matte nyiaj- galvanized coils tuaj yeem ua tiav lub peev nyiaj ci. Cov coils no tuaj yeem siv ncaj qha rau cov chaw muaj hluav taws xob (xws li cov khoom siv hluav taws xob thiab cov nqi tsev ib ntus), txo cov nqi tom ntej.
High Dosensal qhov tseeb: piv txwv li thickness dolance (piv txwv li, ± 0.mm rau cov khoom siv tuab (cov duab ncaj qha lossis sib npaug, cov teeb meem kev sib dhos ua ke.
Khawb thiab hnav tsis kam: kub - dip galvanized txheej muaj lub hardness ntawm kwv yees li ntawm HV150-200 (siab dua li cov khoom siv hauv paus ntawm HV130). Cov khawb me me (piv txwv li, tshwm sim los ntawm kev sib deev thaum lub sij hawm thauj) tsis zoo li nkag mus rau lub zinc txheej, thaum tswj qee qhov kev ua kom xeb.
5.Qhov dab tsi yog qhov tseem ceeb yog qhov zoo thiab siv cov xwm txheej ntawm Q345B Galvanized Chev?
Cov yam ntxwv ua kom zoo ntawm Q345B galvanized chev tuaj yeem suav tau tias yog cov kabmob zoo tshaj plaws rau cov kev siv ob qho tib si muaj zog, xws li:
Kev Tsim Kho: Cov Prair qauv Purlins, Prefabricated lub tsev thav ntawv, thiab sab nrauv phab ntsa lauj kaub av;
Kev Thauj Mus Los: Automotive Lub Cev Kev Txhawb Nqa, Cov Tsheb Txom Panels, thiab Thawv Sab Sab;
Machinery: Kev Tsim Machinery Cov Khoom Siv Khaub Ncaws Thiab Cov Khoom Siv Clipe;
Cov khoom siv hauv tsev: thauj {{- Cov muag cov rooj zaum rau cov khoom siv loj (xws li tub yees thiab cua txias).
