High galvanizing txheej txhais tau hais tias cov txheej yog tuab heev, uas yog rau kub-dip galvanizing, vim electro-galvanizing tsis tuaj yeem plated heev tuab. Lub thickness ntawm kub-dip galvanized txheej yog feem ntau ntau tshaj 20 microns, thiab tuaj yeem ncav cuag ntau tshaj 100 microns. Feem ntau siv hnyav ntawm galvanized txheej ib square meter yog 145 grams / square meter, thiab txheej yog txog 20 microns. Txawm li cas los xij, nws tsis yooj yim los tswj lub thickness ntawm kub-dip galvanizing nyob rau hauv ib tug kuj nyias ntau yam.
Lub melting point ntawm zinc yog 419.5 degree thiab nws cov khoom siv tshuaj muaj zog. Nyob rau hauv cov huab cua ntawm chav tsev kub, ib tug nyias thiab ntom yooj yim zinc carbonate zaj duab xis yog tsim nyob rau saum npoo, uas yuav tiv thaiv tau oxidation ntxiv. Thaum qhov kub nce mus txog 225 degree, zinc yog hnyav oxidized thiab dawb zinc oxide tshwm. Tom qab kub-kub barbecue, txheej los tiv thaiv corrosion ntawm daim ntawv galvanized yog oxidized. Yog li ntawd, cov ntawv galvanized tsis tuaj yeem tiv taus qhov kub thiab txias. Cov nplaim hluav taws kub yuav hloov xim, lossis lwm yam tshuaj tiv thaiv ntawm qhov chaw yuav yooj yim tig daj tom qab oxidation.
Qhov saum npoo ntawmgalvanized ntawvyuav tsum tsis muaj roj, siv quav ciab, thiab lwm yam stains lossis hmoov av, uas tuaj yeem txhim kho qhov adhesion ntawm putty;
Txoj kev xav, nws tsis pom zoo kom siv cov xim pleev xim los yog primer rau ntawm qhov chaw uas du heev, xws li cov ntawv galvanized. Yog tias tsim nyog, kev kho corrosion (xws li hydrochloric acid) yuav tsum tau ua los txhim kho lub zog sib txuas nrog putty thiab xim;
Lub putty yuav tsum tau kho raws li tus qauv piv thiab qhov kev faib ua feem ntawm tus neeg sawv cev curing. Kev faib ua ntau dhau yuav txo qhov adhesion thiab lub cev lub cev ntawm putty (xws li cov brittleness ntau dhau thiab poob ntawm toughness);
Lub putty yuav tsum tau siv nyob rau hauv lub txee lub neej thiab yuav tsum tau thov raws li thinly li sai tau los tiv thaiv qhov kub ntawm qhov sib txawv ntawm qhov chaw thiab lub hauv paus galvanized ntawv los ntawm loj heev thiab ua rau inconsistent kev nyuaj siab, shrinkage thiab expansion, ua rau lub txheej ntog thiab txhuas. ua kom tiav kev sib cais.
Kev txheeb xyuas qhov zoo ntawm cov ntaub ntawv galvanized
Galvanized ntawv yog ib daim ntawv nrog ib txheej ntawm zinc rau ntawm qhov chaw. Tam sim no, kev siv nyiaj txiag thiab siv tau zoo los tiv thaiv corrosion ntawm lub khw, thiab qhov no yog galvanizing. Txog tam sim no, tsawg kawg ib nrab ntawm zinc tsim nyob rau hauv lub ntiaj teb no tau ua txheej txheem Galvanizing rau cov ntawv hlau. Cov txheej txheem no tuaj yeem tiv thaiv qhov saum npoo ntawm cov phaj hlau los ntawm kev oxidized los yog corroded los ntawm cov kua, ncua lub neej kev pab cuam ntawm lub phaj thiab txuag tau ntau ntawm phau ntawv kev xav tau kev pab.
Tam sim no, cov khoom siv no tau siv dav hauv kev tsim kho kev lag luam, thiab nws kuj tseem maj mam siv hauv tsheb, guardrails, anti-corrosion steel, thiab lwm yam. Cov tsoos steel tau muab tso rau hauv kev lag luam tom qab kev kho yooj yim los tiv thaiv xeb, thiab nws cov kev pabcuam lub neej tsuas yog ob peb xyoos xwb. Cov ntaub ntawv tshiab galvanized tau hloov cov tsoos hlau, thiab nws cov kev ua tau zoo tau raug sim los ntawm ntau qhov kev sim thiab cov neeg siv kev paub. Nws tau raug lees paub, thiab cov ntaub ntawv tshwj xeeb tuaj yeem pom los ntawm cov ntaub ntawv luam tawm los ntawm cov chaw tsim khoom.
Nyob rau hauv xyoo tas los no, ntau yam khoom siv hlau tau tshwm sim, thiab lawv cov kev tiv thaiv corrosion, prototyping sai, thiab txheej txheej tau zoo heev. Los ntawm kev sib sau ua ke ntawm kev siv tshuab, cov nqi tsim khoom tau raug txo, thiab cov tsos tau zoo nkauj dua. . Yog tias koj xav paub ntau ntxiv txog cov ntawv galvanized, koj tuaj yeem tiv tauj peb.
