1.Vim li cas galvanized coils siv tau?
Galvanized coils muaj xeb- pov thawj muaj peev xwm thiab tuaj yeem tiv taus qee qhov chaw ntub dej hauv thaj av. Los ntawm kev pom kev tiv thaiv corrosion, lawv muaj zog dua li cov ntawv txias txias -rolled sheets.
2.Dab tsi yog vim li cas rau "tsis nquag siv"?
Insufficient Abrasion Resistance (Qhov teeb meem tseem ceeb tshaj plaws)
Thaum lub sij hawm ua haujlwm, lub cutter guard phaj ntawm lub tshuab txiav tuaj rau hauv kev sib txhuam ncaj qha nrog cov qoob loo (tshwj xeeb tshaj yog nplej thiab nplej straw) thiab cov av thiab xuab zeb. Cov txheej txheej galvanized nws tus kheej yog qhov muag muag thiab muaj kev puas tsuaj tsis zoo.
Nyob rau hauv kev sib txhuam tsis tu ncua, zinc txheej yuav raug hnav sai sai. Thaum cov hlau substrate raug nthuav tawm, corrosion yuav pib sai, ua rau nws tsis zoo rau kev tiv thaiv corrosion.
Tsis txaus Nto Hardness, yooj yim khawb
Thaum lub sij hawm sau qoob, lub phaj tiv thaiv yuav ntsib cov khoom tawv xws li pob zeb. Qhov saum npoo hardness ntawm galvanized txheej yog tsis txaus los tiv thaiv xws li cuam tshuam thiab khawb, yooj yim ua rau zinc txheej puas.
Nqi thiab txheej txheem teeb meem
Cov phaj tiv thaiv yuav tsum tau tsim los ntawm cov txheej txheem xws li stamping thiab dabtsi yog khoov. Thaum siv cov galvanized coils (tshwj xeeb tshaj yog kub-dip galvanized coils) rau stamping, zinc txheej tuaj yeem khaws cia rau ntawm pwm, cuam tshuam rau kev tsim khoom thiab pwm lub neej. Ib txhij, cov npoo ntawm stamping thiab dabtsi yog khoov yuav nthuav tawm lub substrate, ua qhov pib ntawm corrosion.
Piv nrog rau ntau txoj hauv kev ua lag luam, kev siv cov khoom siv galvanized coil yuav tsis pheej yig.
3.Yuav ua li cas xaiv lub substrate?
Cov phaj tiv thaiv yuav tsum muaj qee lub zog thiab tawv, thiab feem ntau yog ua los ntawm cov hlau tshwj xeeb.
4.Dab tsi yog qhov zoo ntawm kev txau tom qab molding?
Muaj zog txheej adhesion: phosphate txheej muab ib qho zoo heev substrate rau txheej adhesion.
Kev xaiv txheej txheej siab: Cov txheej txheem tshwj xeeb nrog kev hnav zoo heev thiab huab cua tsis kam tuaj yeem txau. Qee lub tshuab ua liaj ua teb siab -kawg siv epoxy resin, polyurethane, thiab lwm yam txheej, uas nws muaj kev tiv thaiv zoo - corrosion thiab hnav tsis kam ua haujlwm deb tshaj li cov txheej txheem galvanized.
Kev sib koom ua ke thiab ua kom zoo nkauj zoo nkauj: tuaj yeem phim tag nrho cov xim ntawm lub tshuab.
Txhua yam - nyob ib puag ncig kev tiv thaiv: Cov txheej tuaj yeem npog tag nrho txhua lub ces kaum ntawm cov khoom ua haujlwm, suav nrog cov npoo thiab khoov, uas tsis tuaj yeem tiv thaiv los ntawm kev txiav thiab cov npoo ntawm galvanized coils.
5.Yuav tsum ua li cas siab -qhov kawg lossis qhov tseem ceeb yuav raug daws?
Rau qee cov ntawv tiv thaiv uas raug hnav hnyav, cov kev kho cua sov xws li quenching yuav raug siv los ua kom lub zog ntawm cov khoom siv hauv paus, lossis cov phaj tuab tuab tuaj yeem siv los txuas ntxiv lub neej kev pab cuam.
