Hauv cov zej zog niaj hnub no, cov ntawv qhia, uas yog ib feem tseem ceeb ntawm cov vaj tse, tau siv dav hauv txoj kev, cov chaw ua si, cov chaw pej xeem, thiab lwm qhov chaw, pab qhia, qhia, thiab ceeb toom. Ntawm lawv, kub -dip galvanized signposts, vim lawv zoo heev durability thiab corrosion kuj, tau dhau los ua kev xaiv rau ntau daim ntawv thov. Tsab ntawv xov xwm no yuav qhia txog kev ua haujlwm ntawm kub -dip galvanized signposts, los ntawm kev xaiv cov khoom siv thiab kev siv thev naus laus zis rau kev tswj kom zoo, pab cov neeg nyeem kom nkag siab zoo txog cov txheej txheem tsim khoom ntawm cov khoom no.
Kev xaiv cov khoom thiab Pretreatment
Kev ua haujlwm ntawm kub -dip galvanized signposts pib nrog kev xaiv cov khoom. Feem ntau, cov khoom tseem ceeb ntawm cov ntawv qhia yog siab -zoo qis- carbon steel. Hom hlau no muaj cov yas zoo thiab weldability, ua tau raws li qhov xav tau ntawm kev ua haujlwm tom ntej. Lub thickness thiab specifications ntawm cov hlau yuav tsum tau txiav txim raws li cov kev siv thiab load- bearing yuav tsum tau ntawm lub signpost kom muaj zog txaus thiab stability nyob rau hauv tiag tiag siv.
Tom qab cov khoom raug txiav thiab zoo li tus, nruj pretreatment yuav tsum tau. Roj, xeb, thiab impurities ntawm lub steel nto yog tshem tawm mechanically los yog manually. Tom qab ntawd, cov txheej txheem acid pickling yog siv los ntxuav qhov chaw ntxiv. Cov tshuaj pickling feem ntau yog diluted hydrochloric acid los yog sulfuric acid tov, uas muaj peev xwm yaj oxide nplai thiab residues zoo. Tom qab pretreatment, cov hlau yuav tsum tau muab yaug nrog dej huv thiab qhuav kom huv si thiab tsis muaj paug nto, nteg lub hauv paus rau tom ntej kub -dip galvanizing txheej txheem.
Cov kauj ruam tseem ceeb ntawm Kub-Dip Galvanizing txheej txheem
Kub-dip galvanizing yog ib kauj ruam tseem ceeb hauv kev tsim cov cim cim. Its purpose is to form a uniform and dense zinc-iron alloy layer on the steel surface, significantly improving the pole's corrosion resistance. Cov txheej txheem feem ntau suav nrog cov kauj ruam hauv qab no:
Immersing lub pretreated steel rau hauv molten zinc. Qhov kub ntawm zinc da dej yuav tsum raug tswj xyuas kom meej nyob rau hauv qhov tsim nyog kom paub meej txaus cov tshuaj tiv thaiv ntawm zinc txheej thiab cov hlau substrate. Lub sij hawm immersion nyob ntawm cov thickness thiab specifications ntawm cov hlau, feem ntau yog li ntawm ob peb feeb mus rau ntau tshaj kaum feeb.
Thaum lub sij hawm immersion txheej txheem, zinc da dej tau txais ib tug metallurgical cov tshuaj tiv thaiv nrog steel nto, ua ib tug multi- txheej zinc- hlau alloy txheej. Cov khaubncaws sab nraud povtseg no tsis yog tsuas yog muaj qhov adhesion zoo xwb tab sis kuj tseem cuam tshuam rau sab nraud ya raws, oxygen, thiab corrosive tshuaj. Tom qab immersion, tus ncej yog maj mam muab tshem tawm los ntawm zinc da dej, thiab ntau tshaj zinc raug tshem tawm los ntawm centrifugation los yog vibration kom ntseeg tau tias ib tug uniform thiab du zinc txheej ntawm qhov chaw.
Tom qab galvanizing, cov ntawv qhia yuav tsum tau txias. Cov txheej txheem cua txias tuaj yeem yog ntuj lossis dej txias, nyob ntawm cov txheej txheem yuav tsum tau ua. Qhov chaw txias yuav tsum muaj cov nyiaj - grey luster, zinc txheej thickness yuav tsum tau raws li cov qauv, thiab yuav tsum tsis txhob muaj qhov tsis xws luag xws li tsis tiav galvanizing lossis blistering.
Tshaj tawm -kev ua haujlwm thiab Kev Kho Hniav
Tom qab kub-dip galvanizing, cov ntawv qhia tau dhau los ua cov kauj ruam ntawm kev tshaj tawm -. Raws li kev tsim qauv, cov phiajcim yog drilled, welded, thiab sib dhos. Cov txheej txheem no yuav tsum tau ua nruj me ntsis raws li cov duab kos kom ntseeg tau tias cov cim kos npe qhov ntev thiab cov duab yog qhov tseeb.
Vuam yog ib kauj ruam tseem ceeb hauv kev ua haujlwm tom qab-. Welds yuav tsum zoo ib yam thiab muaj zog, tsis muaj qhov tsis tiav los yog faulty welds. Tom qab welding, weld seams yuav tsum yog hauv av los xyuas kom meej ib tug du thiab txawm nto, raws li tus so ntawm lub signpost.
Kev kho deg ntawm cov ntawv kos npe kuj suav nrog cov txheej txheem xws li txau thiab luam ntawv. Piv txwv li, ib txheej tshwj xeeb tuaj yeem muab txau rau hauv txheej txheej galvanized los txhim kho nws cov huab cua tiv thaiv thiab kev zoo nkauj. Cov xim xim feem ntau yog xaiv raws li qhov yuav tsum tau ua ntawm kev siv ib puag ncig; cov xim muaj xws li dawb thiab grey. Cov ntsiab lus luam tawm suav nrog cov ntawv qhia thiab cov duab kos, yuav tsum tau siv huab cua - cov ntawv tiv thaiv kom ntseeg tau ntev - lub sijhawm pom ntawm cov cim.
Kev Tswjhwm Zoo thiab Kev Ntsuas Cov Qauv
Kev tswj xyuas zoo ntawm kub-dip galvanized kos npe ncej yog khaws cia thoob plaws tag nrho kev ua haujlwm. Los ntawm cov khoom warehouses mus rau tiav cov khoom xa tuaj, txhua kauj ruam yuav tsum tau nruj me ntsis soj ntsuam. Cov khoom siv raw yuav tsum ua raws li cov qauv tsim nyog, suav nrog cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov hlau. Thaum lub sij hawm pretreatment thiab kub -dip galvanizing, cov txheej txheem tsis, xws li pickling kua concentration thiab zinc da dej kub, yuav tsum tau xyuas tsis tu ncua kom paub tseeb tias lawv nyob rau hauv qhov tsim nyog ranges.
Kev tshuaj xyuas zoo ntawm txheej galvanized yog qhov tseem ceeb. Thickness gauges feem ntau yog siv los ntsuas cov zinc txheej tuab kom ntseeg tau tias muaj kev sib luag thiab ua raws li cov qauv. Kev kuaj adhesion thiab kev kuaj corrosion kuj tseem ua los xyuas qhov tseeb ntawm zinc txheej. Rau cov cheeb tsam welded, tsis yog -kev kuaj kev puas tsuaj, xws li kev kuaj ultrasonic, yuav tsum tau ua kom cov weld seams tsis muaj qhov tsis xws luag.
Qhov luaj li cas, cov duab, thiab qhov zoo li ntawm cov kos npe tiav yuav tsum tau soj ntsuam ib tus zuj zus. Txhua tus ncej uas tsis ua raws li cov kev cai yuav tsum tau rov ua dua lossis muab pov tseg kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom kawg.
