Raws li txoj cai, cov nyees khawm hlau yog hu ua xeb los yog xeb vim corrosion los yog discoloration tshwm sim los ntawm oxygen, noo noo thiab lwm yam impurities impurities nyob rau hauv cov huab cua.Tom qab cov khoom siv hlau ntawm cov yas khawm manufacturers yog xeb, cov teeb pom kev zoo yuav cuam tshuam rau cov tsos zoo, thiab qhov loj yuav cuam tshuam rau kev siv thiab txawm tias ua rau scrapping.Yog li ntawd, cov khoom siv hlau yuav tsum tau khaws cia kom zoo thaum lub sijhawm khaws cia, thiab yuav tsum tau them nyiaj rau kev tiv thaiv xeb.Kub tooj liab khawm
Lub ntsiab yam tseem ceeb uas ua rau hlau nyees khawm kom xeb:
(1) Atmospheric txheeb ze humidity Nyob rau tib qhov kub, qhov feem pua ntawm cov dej vapor ntsiab lus ntawm cov cua thiab nws cov dej saturated vapor ntsiab lus hu ua txheeb ze humidity.Hauv qab qee qhov txheeb ze av noo, tus nqi hlau corrosion tsawg heev, tab sis saum toj no tus txheeb ze av noo, tus nqi corrosion nce sharply.Qhov txheeb ze humidity no hu ua tseem ceeb humidity.Cov av noo tseem ceeb ntawm ntau cov hlau yog nruab nrab ntawm 50% thiab 80%, thiab cov hlau yog li 75%.Atmospheric txheeb ze humidity muaj qhov zoo tshaj plaws cuam tshuam rau hlau corrosion.Thaum cov av noo siab tshaj qhov tseem ceeb ntawm cov av noo, cov yeeb yaj kiab dej los yog cov tee dej yuav tshwm rau ntawm cov hlau.Yog hais tias muaj teeb meem impurities nyob rau hauv cov huab cua yaj nyob rau hauv cov dej zaj duab xis los yog dej tee dej, nws yuav ua tau ib tug electrolyte, uas yuav aggravate lub corrosion.Kub tooj liab khawm
(2) Huab cua kub thiab av noo Kev sib raug zoo ntawm atmospheric kub thiab av noo cuam tshuam rau corrosion ntawm hlau nyees khawm.Qhov no muaj cov yam ntxwv tseem ceeb hauv qab no: ua ntej, cov dej vapor ntsiab lus ntawm cov huab cua nce nrog qhov kub thiab txias;Thib ob, qhov kub thiab txias txhawb kev siv zog ntawm corrosion, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ntub dej, qhov kub thiab txias, qhov ceev ntawm corrosion.Thaum cov txheeb ze cov av qis qis, qhov cuam tshuam ntawm qhov kub ntawm corrosion tsis pom tseeb, tab sis thaum tus txheeb ze av noo siab dua qhov tseem ceeb ntawm cov av noo, qhov corrosion nce sharply nrog qhov kub thiab txias.Tsis tas li ntawd, yog tias muaj qhov kub thiab txias sib txawv ntawm cov cua thiab cov hlau, cov dej condensed yuav tsim rau ntawm cov hlau uas muaj qhov kub thiab txias, uas yuav ua rau cov hlau xeb.Kub tooj liab khawm
(3) Corrosive gases pollute lub corrosive gases nyob rau hauv cov huab cua, thiab sulfur dioxide muaj feem xyuam rau cov hlau corrosion, tshwj xeeb tshaj yog rau tooj liab thiab nws alloys.Sulfur dioxide nyob rau hauv cov huab cua feem ntau yog los ntawm combustion ntawm thee.Nyob rau tib lub sijhawm, cov khoom combustion carbon dioxide kuj muaj cov nyhuv corrosive.Corrosive gases yog tov nyob rau hauv qhov chaw nyob ib ncig ntawm cov nroj tsuag.Xws li hydrogen sulfide, ammonia gas, hydrochloric acid gas, thiab lwm yam yog txhua yam uas txhawb nqa hlau corrosion.
(4) Lwm yam hauv huab cua muaj cov plua plav ntau, xws li smog, thee tshauv, chloride thiab lwm yam kua qaub, alkali, ntsev, thiab lwm yam, qee qhov ntawm lawv tus kheej corrosive, los yog condensation nuclei ntawm cov tee dej, uas yog kuj tseem muaj corrosion.Piv txwv li, chloride raug suav hais tias yog "tus yeeb ncuab tuag" ntawm cov hlau corroding.Kub tooj liab khawm
