Q355NH yog ib qho dav dav - lub hom phiaj huab cua huab cua uas nyob ntawm kev tsim cov patina ruaj khov rau kev tiv thaiv corrosion. Nws qhov kev ua tau zoo hloov pauv loj ntawmqis, ib txwm, thiab siab kub, yog li cov hom phiaj kev txhim kho yog xav tau.
1. Ntawm qhov kub thiab txias (10-35 degree)
Qhov no yog qhovib puag ncig zoorau patina formation.Kev txhim kho kev ntsuas:
Xyuas kom txausntub-qhuav cycles( nag + tshav ) los txhawb nqa patina tuab.
Khaws qhov chawhuv si, tsis muaj roj, hmoov av, thiab cement stains.
Sivnto pretreatment(sandblasting, tua blasting) rau ntau yam patina.
Tsis txhob sib cuag mus ntev nrog dej, av, lossis ntoo.
Rau qhov tseem ceeb, sivhuab cua-match welding cov ntaub ntawvkom muaj kev tiv thaiv corrosion tag nrho.
Cov nyhuv: Patina stabilizes sai, thiab lub sij hawm ntev atmospheric corrosion kuj zoo heev.
2. Ntawm qhov kub thiab txias (qis dua 0 degree, lub caij ntuj no / txias cheeb tsam)
Tsawg kubslows los yog nres tsim patina; snowmelt, deicing ntsev, thiab khov-thaw cycles accelerate corrosion.Kev txhim kho kev ntsuas:
Tiv thaivdeicing ntsev (chloride)hu rau - nws rhuav tshem patina.
Khaws qhov chawqhuavthaum lub sij hawm khov.
Thovepoxy primer + polyurethane topcoatyog siv nyob rau hauv ntug hiav txwv dej los yog salted txoj kev.
SivQ355NHD or Q355NHE(zoo dua qhov kub thiab txias toughness + ruaj khov patina) es tsis txhob yog ua tau.
Xyuas kom cov dej ntws zoo kom tsis txhob muaj dej sib sau thiab khov rau ntawm qhov chaw.
Cov nyhuv: Txo pitting corrosion thiab patina kev puas tsuaj los ntawm qhov kub thiab txias thiab ntsev.
3. Thaum kub kub & lub hnub muaj zog (siab tshaj 40 degree, lub caij ntuj sov / kub qhuav)
Kub kub ceev oxidation nto tab sis nyhav rau daim ntawvxoob xebes tsis txhob ruaj khov patina.Kev txhim kho kev ntsuas:
Zamdryness ntev- Txau dej kom zoo ib ntus kom tsim cov voj voog ntub-qhuav.
Tiv thaiv kom tsis txhob muaj plua plav ntau dhau, uas cuam tshuam cov dej noo.
Rau cov qauv sab nraum zoov, zam ib sab mus ntev raug rau cov hluav taws kub hnyav heev.
Yog siv ze qhov chaw kub, ntxivtshav kub rwb thaiv tsev los yog tiv thaiv txheejkom txo qhov kub qhov sib txawv corrosion.
Cov nyhuv: Txhawb nqa compact patina es tsis txhob powdery xeb.
4. Nyob rau hauv high humidity / rainy / tropical kub ib puag ncig
High humidity + kub kub yooj yim uanruam rusting; patina tsis tuaj yeem ruaj khov.
Ntxiv dag zogqhov cuakom tsis txhob ntub dej mus ntev.
Sivceev patina kev kho mobkom sai tsim cov txheej txheem tiv thaiv.
Thovpob tshab anti-xeb sealerkom txo cov nag yaig.
Txhim kho cov qauv rau kev tso dej, tsis muaj qhov khoob lossis cov qhov uas tuav dej.
Cov nyhuv: Tiv thaiv kom tsis txhob xeb ntau dhau thiab lub hauv paus perforation corrosion.
5. Universal txoj kev los txhim kho corrosion kuj ntawm Q355NH
Xaivhigh-qib weathering steel(Q355GNH, Q345GNH, SPA-H) rau ib puag ncig hnyav.
Sivprofessional anti-corrosion txheejnyob rau hauv qhov chaw uas tsis yog atmospheric (faus, immersed, av sib cuag).
Tswjnto zooThaum lub sij hawm fabrication: tsis muaj khawb tob, tsis muaj roj paug, uniform roughness.
Sivsib piv huab cua welding cov ntaub ntawvkom tsis txhob weld corrosion.
