Environmental yam cuam tshuam rau cov xim-coated panels
Ntsib nrog ntau hom txheej txheej, peb yuav tsum xaiv li cas?Cia kuv qhia ntau yam ib puag ncig uas cuam tshuam rau kev siv cov xim coated boards.
1. Kub
Cov txheej yog yooj yim rau soften ntawm qhov kub thiab txias, thiab corrosive nruab nrab yog ib qho yooj yim rau adhere.Nws yog ib qho yooj yim rau nkag mus rau hauv lub substrate, cov ntsiab lus ntawm cov pa oxygen nyob rau hauv dej yuav nce nyob rau hauv high kub, thiab corrosion yuav nce nyob rau hauv ib tug tej yam kub thiab txias.
2. Cov av noo
Qhov corrosion ntawm lub substrate ntawm kev txiav thiab ua kev puas tsuaj ntawm cov xim-coated board belongs rau electrochemical corrosion, thiab cov av noo tsawg tsis yooj yim los tsim cov roj teeb corrosion (xws li electrochemical circuit).
3, Qhov kub sib txawv nruab hnub thiab hmo ntuj
Qhov loj kub sib txawv yog yooj yim rau condense, tsim ib tug galvanic corrosion mob ntawm liab qab hlau.Tsis tas li ntawd, qhov sib txawv ntawm qhov kub thiab txias kuj tseem ua rau muaj qhov txias thiab kub deformation ntawm txheej txheej, uas yuav ua rau kom cov laus thiab xoob ntawm txheej txheej, thiab qhov nruab nrab corrosive sab nraud yuav yooj yim nkag mus rau hauv lub substrate.
4. Lub sij hawm tshav ntuj thiab kev siv zog
Kev taw qhia thiab txoj kab nqes cuam tshuam rau lub sijhawm ntawm tshav ntuj thiab yog li lub sijhawm ntev ntawm cov txheej.Txoj kab nqes kuj tseem cuam tshuam rau lub sijhawm daws teeb meem ntawm corrosive media lossis plua plav ntawm cov phaj hlau.Hnub ci yog hluav taws xob nthwv dej, uas tau muab faib ua gamma rays, X-rays, ultraviolet rays, pom lub teeb, infrared rays, microwaves thiab xov tooj cua tsis raws li lawv lub zog thiab zaus.Cov nthwv dej thiab xov tooj cua tsis muaj zog thiab tsis cuam tshuam nrog cov teeb meem.Infrared kuj yog lub zog qis.Nws tsuas tuaj yeem ncab lossis khoov cov tshuaj sib txuas ntawm cov tshuaj, tab sis tsis tuaj yeem tawg lawv.Pom pom lub teeb muab txhua yam xim nplua nuj.UV spectrum yog ib qho hluav taws xob ntau zaus, uas muaj lub zog puas tsuaj ntau dua li lub zog qis.Raws li peb paub, cov tawv nqaij tsaus nti thiab mob qog noj ntshav yog tshwm sim los ntawm lub hnub ci ultraviolet rays.Ib yam li ntawd, UV kuj tuaj yeem rhuav tshem cov tshuaj lom neeg ntawm cov tshuaj, ua rau lawv tawg.Qhov no nyob ntawm UV wavelength thiab cov tshuaj tiv thaiv lub zog ntawm cov khoom.X-rays muaj kev nkag mus.Gamma rays tuaj yeem rhuav tshem cov tshuaj sib txuas ntawm cov tshuaj thiab tsim cov ions dawb xwb.Cov no yog cov tuag rau cov organic teeb meem.Hmoov zoo, cov rays no tsawg heev nyob rau hauv tshav ntuj.Yog li ntawd, nws tuaj yeem pom los ntawm cov saum toj no tias lub hnub ci lub sij hawm thiab kev siv zog cuam tshuam rau kev ruaj ntseg ntawm txheej txheej, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj zog ultraviolet rays.
5. Los nag thiab acidity
Rainfall acidity yog undoubtedly detrimental rau corrosion kuj.Txawm li cas los xij, dej nag muaj ob qho txiaj ntsig.Rau cov phab ntsa vaj huam sib luag thiab lub ru tsev panels nrog cov nqes hav loj, cov dej nag tuaj yeem ntxuav cov phaj steel thiab ntxuav cov khoom siv corrosion.Txawm li cas los xij, rau lub ru tsev panels uas tsis tshua muaj nqes thiab cov cheeb tsam uas muaj cov dej tsis zoo, cov dej nag loj yuav yooj yim ua rau corrosion kom nce.
6. Cua kev taw qhia thiab ceev
Cov nyhuv ntawm cua kev taw qhia thiab cua ceev zoo ib yam li cov dej, thiab lawv feem ntau nrog.Nws yog ib qho kev sim rau kev sib txuas ntawm cov khoom siv, vim tias cua yuav ua rau kev sib txuas kom xoob thiab cov dej nag yuav nkag mus rau sab hauv ntawm lub tsev.
7. Corrosion thiab sedimentation
Piv txwv li, cov tshuaj chloride ions, sulfur dioxide, thiab lwm yam muaj cov nyhuv acceleration ntawm corrosion, thiab cov sediments feem ntau tshwm sim ntawm ntug hiav txwv dej thiab nyob rau hauv cov cheeb tsam uas muaj cov pa phem loj (xws li fais fab nroj tsuag, smelters, thiab lwm yam).
