Tsis tu ncua Spanglegalvanized steel yob yog tsim los ntawm txias yob nyob rau hauv txawv specifications nrog zine txheej nyob rau saum npoo, tiv thaiv cov hlau nto los ntawm corrosion, thiab kom ntev kev pab cuam lub sij hawm.
Spangle txhais li cas?
Lub spangle yog qhov pom kev zoo nkauj ntawm crystallites ntawm qhov chaw ntawm cov ntawv hlau galvanized. Lub spangle tshwm raws li ib tug snowflake los yog ib tug rau-taw lub hnub qub qauv. Qhov no yog tsim los ntawm cov ntawv hlau thaum qee cov ntsiab lus alloying yog ntxiv rau cov kua zinc lossis muaj raws li impurities.
Qhov loj thiab kev taw qhia ntawm zinc grain cuam tshuam rau corrosion thiab mechanical zog ntawm zinc alloy.
Spangles muab cov zinc txheej ib lub ntsej muag zoo nkauj txiav txim siab los ntawm kev taw qhia ntawm zinc muaju thiab kev faib tawm ntawm cov ntsiab lus alloying hauv txheej.
Kub dip galvanizing ntau lawm
Tau muab dov rau hauv lub tshuab txias txias-dov thiab xa mus rau cov kab txuas ntxiv kub-dip gavanizing kab los ntxuav electrolytically, lub strip yog thawj zaug yuav tsum tau annealed nyob rau hauv ib tug continonous annealing rauv thiab ces dipped nyob rau hauv lub molten zinc lauj kaub rau kub-dip galvanization. Cov khoom yog thaum kawg muab tawm tom qab passivation los yog daim tawv nqaij-pass, stretcher leveling thiab tsim nyog txoj kev kho mob. Lub hauv paus steel yog galvanized, vim hais tias cov zinc tuaj yeem tsim ib daim nyias nyias ntawm qhov chaw uas muaj kev ua tau zoo nyob rau hauv ib puag ncig corroding. Nws tsis tau tsuas yog tiv thaiv cov zinc txheej tab sis kuj tiv thaiv lub hauv paus steel. Yog li ntawd nws txoj kev pab lub neej yuav ntev heev. Nws tau raug siv hauv architecture, khoom siv hluav taws xob hauv tsev, nws pib mobile, receptacle, tsheb khiav thiab lwm yam.
