Ntau tus neeg yuav khoom xav paub yog tias Q295NH Corten Steel tuaj yeem tiv taus cov xwm txheej hnyav ntawm thaj chaw muaj kev lag luam hnyav - qhov twg acidic fumes, corrosive plua plav, thiab high humidity accelerate steel corrosion sai dua li qhov chaw sab nraum zoov. Q295NH paub txog huab cua tsis kam, tab sis cov chaw lag luam hnyav ua rau muaj kev sib tw tshwj xeeb. Yog li, nws puas yog qhov kev xaiv zoo? Raws li cov ntaub ntawv kuaj corrosion thiab kev ua lag luam, cov lus teb tseem ceeb yog qhov tseeb:Q295NH tsis yog qhov zoo tagnrho rau lub sijhawm ntev -, kev siv tsis muaj kev tiv thaiv hauv thaj chaw muaj kev lag luam hnyav, tab sis tuaj yeem siv rau qhov tsis yog - cov txheej txheem pabcuam tseem ceeb nrog kev tiv thaiv zoo dua. Hauv qab no yog cov lus qhia yooj yim, ua tau zoo.
Ua ntej: Dab tsi ua rau Heavy Industrial Zones Corrosive?
Heavy industrial tsam (xws li, tshuaj nroj tsuag, metallurgical chaw, refineries) muaj corrosive tej yam kev mob uas tshaj Q295NH tus qauv tsim txwv:
Acidic / alkaline fumes: Emissions los ntawm cov txheej txheem ntau lawm ua rau kom xeb thiab rhuav tshem cov patina.
Corrosive plua plav: Hlau oxides, ntsev, lossis tshuaj lom neeg nyob rau ntawm qhov chaw, ua rau thaj chaw pitting corrosion.
High humidity: Muaj cov txheej txheem feem ntau nce ambient humidity, accelerating electrochemical corrosion.
Q295NH's Suitability: Los ntawm Industrial Zone Hom
Q295NH qhov kev ua tau zoo nyob ntawm seb qhov chaw muaj kev lag luam hnyav npaum li cas - ntawm no yog qhov ua tau zoo:
1. Tsis tsim nyog: Cov Hnyav Hnyav Muaj Zog
Cov xwm txheej: Chemical nroj tsuag, refineries, los yog metallurgical chaw uas muaj chemical emissions ncaj qha.
Kev pheej hmoo: Tsis muaj kev tiv thaiv Q295NH yuav tsim pitting corrosion nyob rau hauv 6-12 lub hlis; nws cov patina tsis tuaj yeem tiv taus cov tshuaj lom neeg muaj zog, ua rau ua tsis tiav ntxov.
Kev pom zoo: Xaiv high-corrosion-cov hlau tsis kam (xws li 316L stainless hlau) hloov.
2. Conditionally haum: Me Hnyav Industrial Zones
Cov xwm txheej: Cov chaw tsim khoom teeb pom kev zoo, chaw khaws khoom, lossis chaw pabcuam (tsis muaj tshuaj lom neeg ncaj qha).
Siv Case: Tsuas yog rau cov uas tsis yog- tseem ceeb, qis- cov qauv thauj khoom (xws li, qhov cua qhov ducts, kev txhawb nqa me me, cov khib nyiab cia).
Yuav tsum tiv thaiv: Ob - txheej txheej txheej txheej (zinc-nplua nuj epoxy primer + fluoropolymer topcoat) los thaiv cov kab mob corrosive.
Kev tiv thaiv tseem ceeb (Yog siv Q295NH)
Yog tias Q295NH siv nyob rau hauv cov cheeb tsam hnyav hnyav, cov kev ntsuas no tsis yog - sib tham kom txuas ntxiv nws lub neej kev pabcuam:
Txheej: Siv 80-100μm zinc-nplua nuj primer + 40-60μm fluoropolymer topcoat (tiv thaiv cov tshuaj thiab UV rays).
Kev tu tsis tu ncua: Tshawb xyuas thiab kov cov txheej txheem txhua 1-2 xyoos; ntxuav qhov chaw kom tshem tawm cov plua plav corrosive.
Tsis txhob cuam tshuam ncaj qha: Nruab Q295NH cov khoom kom deb ntawm cov ntsiab lus tshuaj emissions lossis cov pa tso pa tawm.,
Hauv cov ntsiab lus, Q295NH Corten Steel tsis yog tsim los rau cov chaw lag luam hnyav hnyav. Nws tsuas yog siv tau rau hauv cov chaw ua haujlwm me me, nrog cov txheej tiv thaiv nruj thiab kev saib xyuas tsis tu ncua. Rau cov qauv tseem ceeb lossis ib puag ncig tshuaj lom neeg hnyav, xaiv ntau dua corrosion-cov ntaub ntawv tiv taus kom tsis txhob raug nqi rov ua dua.
