1.Thaum nws cov xim pleev xim tsis zoo?
Zuag du nto: Zinc Txheej muaj cov muaju ntom ntom thiab tsis muaj zog saum npoo av, ua rau nws pleev xim nyuaj rau "lauj."
Tshuaj lom neeg INTERTENTY: Lub zinc txheej feem ntau muaj cov oxide nyias lossis cov yeeb yaj kiab passivation ntawm nws cov nplaim dej. Zaj duab xis no tiv thaiv kev xeb ntxiv, tab sis kuj tseem cog lus tau zoo ntawm cov xim thiab cov zinc.
Yog tias koj siv cov tshuaj pleev xim ncaj qha, cov xim pleev xim pleev xim yuav tshwm sim zoo nyob rau hauv lub luv luv, tab sis tom qab lub sij hawm kev co, lossis av noo, nws yuav pib yaug tawm.
2.What yog qee txoj hauv kev los ua kom nce ro ..
Txoj kev zoo tshaj plaws: phosphating. Cov txheej txheem tshuaj tshuaj no tsim cov yeeb yaj kiab phosphate rau ntawm zinc nto. Zaj duab xis no muaj ntxeem tau thiab muaj kev sib raug zoo rau lub substrate, ua rau nws lub hauv paus zoo tshaj plaws rau cov xim pleev xim. Txoj kev no feem ntau siv hauv kev lag luam kev lag luam.

Tseem Ceeb: Siv lub siab maj mam tsuas yog polish deb ntawm zaj duab xis passive; Tsis txhob hnav los ntawm zinc txheej.
Txoj kev yooj yim: huab cua ntuj: tawm hauv Galvanized coil tawm sab nraud rau 3-6 lub hlis kom cia ib txheej ntawm cov ntsev dowurally, uas cov khoom noj khoom ntxiv. Txawm li cas los xij, cov qauv no siv sijhawm ntev heev thiab cov txiaj ntsig yog qhov tsis txaus ntseeg, yog li nws tsis pom zoo.
3.How los xaiv qhov tseem ceeb tshaj plaws?
Epoxy Zinc Primer Daj: Qhov no yog kev xaiv tshwj xeeb uas tau xaiv tshwj xeeb tsim rau cov chaw galvanized, muab adhesion zoo.
Epoxy Zinc - Nple Mesh Primer: Muaj kev sib raug zoo heev thiab kev tiv thaiv xeb.
Dej -}} Raws Acrylic Primer: Ib puag ncig phooj ywg thiab ib qho qauv tam sim no.
Zam: Alkyd thiab roj {{{0} Raws li cov primers. Cov roj nyob rau hauv cov xim muaj no tuaj yeem saponify lub zinc, ua rau cov xim zaj duab xis los flake.
4.Qhov txau pleev tshuaj txau xim coated coils?
On xim {-}} Coated pan cov kab ntau lawm, xws li phosphating thiab cov khoom lag luam uas muaj kev sib tw nrog cov thawj coj, thiab topcoating. The paint film quality, durability, and adhesion are far beyond the reach of on-site manual spraying.
