1.What yog qhov cuam tshuam rau lub neej tiv thaiv corrosion?
Cov txheej txheem los tiv thaiv corrosations ntawm cov galvanized txheej yog los tiv thaiv lub substrate los ntawm kev txi anode cuam tshuam thiab lub cev thaiv cov nyhuv ntawm zinc. Cov tuab tuab cov zinc txheej (qhov hnyav dua nws yog), lub zog tiv thaiv kev tiv thaiv corrosion thiab lub neej ntev.
2.Yog li cas ib puag ncig corrosive muaj rau lub neej pabcuam?
Nyob rau hauv xws li ib puag ncig, cov txheej zinc ib zaug yog noj qeeb (txhua xyoo Corrosion tus nqi yog li 1-3G / ㎡).
Yog tias qhov sib txawv hauv cov txheej zinc yog 5G / ㎡: daim tseem 80-3 xyoos, qhov sib txawv tsuas yog muaj li ntawm 23-28 xyoo, txij li kev siv deg, txij nkawm tsis pom tseeb.
Yog tias qhov sib txawv yog 10g / ㎡: Lub neej ntev tshaj plaws yog kwv yees li ntawm kev kho kom zoo nkauj thiab cov khoom noj tsawg li cov rooj tog zaum).
3.Yog dab tsi ua rau muaj kev tiv thaiv muaj teeb meem muaj rau ntawm lub neej pabcuam?
Qhov feem ntau ntawm kev corrosion ntawm zinc txheej yog li 3-8g / ㎡, thiab kev cuam tshuam ntawm ob peb gram ntawm qhov sib txawv yuav ua rau muaj zog.
5g qhov sib txawv: Lub neej ntawm zinc txheej ntawm 80g / ㎡ yog li 10-15 xyoo, thiab 75g / ㎡ / ㎡ yog li 9-2 xyoos; Yog tias siv rau tus saib xyuas sab nraud thiab cov qauv hlau zoo tib yam, nws tuaj yeem ua rau muaj xeb ua ntej (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus (xws li vuam cov ntsiab lus thiab cov npoo).
10g qhov sib txawv: Lub neej luv los ntawm 2-4 xyoos. Yog tias cov qauv tsim lub neej yuav tsum yog 15 xyoo, qhov txawv ntawm 10G yuav ua rau muaj kev tu tus nqi tom qab tom qab (xws li rov ua dua tshiab thiab hloov).
4.Yog cuam tshuam ib puag ncig phem (xws li thaj chaw ntug dej hiav txwv, chaw muaj chaw nyob, thiab thaj chaw siab dav?
Cov feem ntau corrosion ntawm zinc txheej tuaj yeem ncav cuag 8-20g / ㎡, thiab qhov sib txawv ntawm "ob peb gram" muaj qhov cuam tshuam tseem ceeb.
5G Qhov Txawv: Piv Txwv, Hauv Chaw Ntug Dej Nqaum (Cov Salinity siab), thiab 75 xyoo, tab sis 75 xyoo, tab sis 75 xyoo) vim yog kev ua kom dawb huv ntawm lub zos zinc txheej.
10g qhov sib txawv: Lub neej luv los ntawm 1-3 xyoos. Yog tias siv hauv cov cuab yeej siv tshuaj, marine engineering thiab lwm qhov scenes uas tsis tshua muaj neeg tiv thaiv corrosion, xws li txheej txheem nkag mus, xws li cuam tshuam ncaj qha), uas cuam tshuam ncaj qha rau cov khoom muaj kev nyab xeeb.
5.Qhov dab tsi ua ob peb grams ntawm zinc txheej muaj ntawm kev ua tiav kev ua tau zoo?
Nyias zinc txheej: yog tias qhov sib txawv yog 5g, lub zos zinc txheej yuav yog cov dhau nyias. Thaum lub sij hawm stamping thiab khoov, qhov chaw zinc nyias yog qhov dhau los ntawm kev tawm tsam ntau dhau ntawm substrate, ua rau "muaj kev pheej hmoo ntawm kev xeb tom qab.
Tuab zinc txheej: yog tias qhov sib txawv yog 10g, cov txheej tuab tuab tuab yuav ua rau muaj ntau zinc vapor thaum lub ntsej muag, lossis tawg vim tias cov txheej zinc ntawm zinc.
