Ib pob ntawv uas muaj 96% zinc hauv zaj duab xis qhuav, lwm txoj kev tiv thaiv corrosion rau kub poob
Kev piav qhia
ZINDN yog ib pob galvanizing txheej uas muaj 96% zinc plua plav hauv cov yeeb yaj kiab qhuav thiab muab ob qho tib si cathodic thiab thaiv kev tiv thaiv ntawm ferrous hlau.
Nws tuaj yeem siv tsis tau tsuas yog lub cim tshwj xeeb los ua lwm txoj kev tiv thaiv kev ua haujlwm rau kub-dip galvanizing, tab sis raws li primer hauv duplex system lossis peb txheej ZINDN txheej txheej.
Nws tuaj yeem siv tau los ntawm kev txau, txhuam los yog dov rau ntawm ib qho huv thiab ntxhib hlau substrate nyob rau hauv ntau yam atmospheric.
Cathodic tiv thaiv
Nyob rau hauv electrochemical corrosion, cov hlau zinc thiab hlau yog nyob rau hauv kev sib cuag nrog ib tug, thiab cov zinc nrog ib tug tsawg electrode peev xwm yog siv raws li lub anode, uas tsis tu ncua poob electrons thiab corroded, uas yog, lub sacrificial anode;thaum cov hlau nws tus kheej yog siv los ua cathode, uas tsuas yog hloov hluav taws xob thiab tsis hloov nws tus kheej, yog li nws muaj kev tiv thaiv.
Cov ntsiab lus zinc hauv ZINDN galvanizing txheej yog tshaj 95%, thiab purity ntawm zinc hmoov siv yog siab li 99.995%.Txawm hais tias txheej txheej galvanizing me ntsis puas lawm, cov hlau hauv qab zinc txheej yuav tsis xeb kom txog thaum zinc tau noj tag, thiab lub sijhawm no, nws tuaj yeem tiv thaiv kev sib kis ntawm xeb.
Barrier tiv thaiv
Cov tshuaj tiv thaiv kev tshwj xeeb ua rau zindn galvanizing txheej xwm txuas ntxiv nrog lub sijhawm sib tw, ua kom muaj kev sib cais tau zoo ntawm kev tiv thaiv corrosion.
ZINDN muab cov yam ntxwv ntawm ob qho kev tiv thaiv corrosion rau hauv ib qho, tawg los ntawm kev txwv ntawm cov xim-piv piv ntawm cov pa coatings, thiab tau txais txiaj ntsig zoo rau lub sijhawm ntev los tiv thaiv corrosion.
95% zinc plua plav nyob rau hauv ZINDN galvanizing txheej qhuav zaj duab xis, corrosion tam sim no ceev yog ntau dua li ntawm zinc-nplua nuj txheej.
Nrog rau qhov nce ntawm zinc hmoov av nyob rau hauv qhuav zaj duab xis txheej, corrosion tam sim no ceev yuav nce ho, thiab electrochemical anti-corrosion peev xwm kuj yuav nce ho.
Qhov zoo ntawm ZINDN
Lub sij hawm ntev los tiv thaiv corrosion
Active + Passive dual tiv thaiv cov khoom, ntsev tshuaj tsuag mus txog 4500 teev, yooj yim ua tiav rau 25+ xyoo anticorrosion lub neej ncua.
Muaj zog adhesion
Tus tsim fusion tus neeg sawv cev thev naus laus zis tau daws qhov teeb meem adhesion ntawm siab zinc plua plav (> 95%) hauv zaj duab xis qhuav.4% pawg ntawm fusion tus neeg sawv cev tuaj yeem ruaj khov 24 npaug ntawm nws qhov hnyav ntawm zinc plua plav thiab ua rau nws sib raug zoo nrog cov substrate thiab adhesion mus txog 5Mpa-10Mpa.
Zoo sib xws
ZINDN tuaj yeem siv los ua ib txheej los yog ob lossis peb txheej txheej nrog ZD sealer, topcoat, nyiaj zinc, thiab lwm yam, kom tau raws li cov neeg siv khoom xav tau kev tiv thaiv ntev ntev thiab kho kom zoo nkauj hauv ntau yam ib puag ncig.
Tsis muaj cracking los yog ntog tawm siv nyob rau hauv weld
ZINDN daws cov kev lag luam bottleneck uas galvanizing txheej yooj yim tawg thiab poob rau hauv cov vuam, ua kom cov ntawv thov zoo.
Yooj yim rau kev thov
Ib pob, tuaj yeem siv los ntawm kev txau, txhuam los yog dov.Tsis poob rau hauv qab, tsis thaiv phom, tsis thaiv lub twj tso kua mis, yooj yim siv.
Tus nqi zoo
Eco-friendly, tsis tshua muaj nqi, thiab yooj yim touchup piv rau kub-dip thiab thermal spray galvanizing.
Lub sijhawm ntev ntawm kev kov thiab rov ua dua, tus nqi qis ntawm lub neej voj voog anticorrosion piv rau epoxy zinc nplua nuj txheej.
