1.What ib lub luag haujlwm ua si zinc txheej ua si hauv kev txhim kho txheej txheej adhesion?
Inhibit txoj kev loj hlob ntawm brittle alloy txheej: Thaum cov phaj steel yog raus hauv zinc kua, hlau (zn) los ua fe-zn intermetallic tebchaw. Yog tias tsis tswj, ib txheej tuab ntau dhau yuav ua rau cov txheej txheej kom tawg thiab poob tau yooj yim.
Ua ib qho kev tiv thaiv txheej txheem: txhuas yuav hnov mob nrog hlau ua ntej, tsim kev hnav khaub ncaws ua ntej, nrawm fe₂al₅ txheej ntawm cov npoo ntawm cov hlau phaj. Cov txheej txheej no muaj cov qauv ruaj khov thiab zinc thaiv cov tshuaj ntxiv ntawm cov kev sib tw ntawm lub zog ntawm cov txheej thiab cov hlau phaj.
2.Yog li cas ua txhuas nyob rau hauv cov galvanized txheej muaj ntawm qhov loj ntawm zinc paj?
Nce tus naj npawb ntawm Crystal Nuclei thiab inhibit ntau dhau kev loj hlob: aluminium nuclei loj nyob rau hauv tib lub sij hawm, es tsis muaj ob peb lub crystal nuclei "hom".
Thaum cov ntsiab lus txhuas ntau dua los yog sib npaug rau 0.15%, txoj kab uas hla ntawm ob peb lub millimeters ntawm ntshiab zinc kom tsawg dua 1mm; Thaum twg cov ntsiab lus txhuas ntau dua los yog sib npaug rau 0.2%, nws tuaj yeem tsim "Zinc Paj Dawb" saum npoo av "(zinc paj taub<0.3mm, almost invisible to the naked eye).
Cov txiaj ntsig zoo: cov nplaim zinc paj lossis tsis muaj zinc
3. Yam lub luag haujlwm ua dab tsi los ua cov txheej txheem galvanized ua si hauv kev ua haujlwm ntawm cov txheej?
Optimize the microstructure of the coating: The solid solution formed by aluminum and zinc can refine the coating grains, reduce grain boundary defects (such as micropores and impurities), and reduce the penetration rate of corrosive media (water, oxygen).
Ua ib txheej xim dense oxide: Thaum tau los rau ntawm cov txheej txheej ntawm zinc (ntau dua li zinc tau noj ua ib qho zinc yog tau noj ua ib qho kev ua kom zoo).
4.How to toppress "zinc ntws" thiab "xau plating" hauv galvanized txhuas?
Aluminium tuaj yeem txo qhov nro ntawm zinc kua thiab txhim kho lub wettability ntawm zinc kua rau steel phaj:
Txo Zinc Streaks: Tom qab cov wettability tau txhim kho, ntws ntawm zinc kua nyob rau saum npoo ntawm cov steel phaj yog ntau yam tsis xws luag los ntawm kev sib txuam hauv zej zog.
Txo qhov kev pheej hmoo ntawm kev tsis txaus siab plating: Rau cov ntsiab lus oxidation me me ntawm cov kab mob hlau, tshwj xeeb yog los ntawm cov paib hlau uas tsis yooj yim ua ntej.
5.Qhov twg yog qhov sib txawv ntawm cov ntaub ntawv raug cai rau cov ntsiab lus sib txawv cov ntsiab lus sib txawv?
Paj Ntaub me me Galvanized: Nplua Zinc Paj
Tsis muaj-splars daim ntawv: tsis muaj-hnoos qeev + siab + corrosion tsis kam; Cov Khoom Siv Hauv Tsev Hauv Tsev, Tsheb Sab nrauv Panels (yuav tsum tau pleev xim)
Zinc-Txhuas Alloy Txheej: Txhim kho txhim kho corrosion corrosion (3-5 zaug siab dua li ntshiab zinc), kev tsim kho tshuaj lom neeg, kev tsim kho ntug dej)
