Hauv kev tsim vaj tsev thiab kho kom zoo nkauj ntawm cov ntaub ntawv hlau xws li cov kav hlau, cov khoom siv hluav taws xob, thiab cov khoom siv steel, cov txheej txheem kho saum npoo rau cov ntaub ntawv steel ncaj qha cuam tshuam rau lawv lub neej kev pab cuam, kev zoo nkauj, thiab daim ntawv thov scenarios. Raws li peb cov thev naus laus zis thev naus laus zis thev naus laus zis, galvanizing, hmoov txheej, thiab pleev xim rau txhua tus muaj cov yam ntxwv tshwj xeeb uas haum rau qhov sib txawv ntawm ib puag ncig.
Galvanizing sawv tawm raws li qhov kev xaiv zoo tshaj plaws rau cov qauv sab nraum zoov vim nws qhov tshwj xeeb corrosion kuj. Hmoov txheej pom kev siv dav hauv cov khoom siv kho kom zoo nkauj vim nws txoj kev xaiv xim nplua nuj thiab eco- cov khoom zoo. Lub caij no, kev pleev xim ua tau raws li luv luv - lub sijhawm tiv thaiv kev xav tau nrog nws tus nqi -cov txiaj ntsig zoo.
1. Galvanizing
(1) Lub hauv paus ntsiab lus: Tsim cov zinc txheej ntawm cov hlau los ntawm electrochemical lossis kub- cov txheej txheem dip (hom hom: Kub-Dip Galvanizing / HDG, Electro-Galvanizing / EG).
(2) Corrosion Resistance: Zinc muab kev tiv thaiv cathodic (sacrificial anode), muab kev ruaj khov tshwj xeeb (20-50 xyoo sab nraum zoov).
(3) Zoo li: Nyiaj- grey matte tiav, tuaj yeem pom cov qauv siv lead ua zinc ("spangle").
(4) Hardness: Mos zinc txheej (~ 250 HV), khawb - yooj yim tab sis tus kheej - kho me ntsis kev puas tsuaj.
(5) Daim Ntawv Thov: Sab nraum zoov cov qauv (kev sib kis tau zoo, choj railings), cov kav dej hauv av, thaj chaw marine.
(6) Nqi: Nruab nrab mus rau siab (HDG> EG).
2. Hmoov Txheej
(1) Lub hauv paus ntsiab lus: Electrostatic daim ntawv thov ntawm cov hmoov polymer (epoxy / polyester), kho nyob rau hauv tshav kub los tsim ib txheej yas.
(2) Corrosion Resistance: Zoo dua li cov xim ua kua tab sis qis dua galvanizing; resists tshuaj / UV (vim los ntawm hom hmoov).
(3) Cov tsos: Cov xim dav (kev cai RAL codes), du lossis textured (xws li, xuab zeb, wrinkle tiav).
(4) Hardness: Siab (Ntau dua los yog sib npaug rau 2H mem hluav hardness), abrasion - thiab cuam tshuam -resistant.
(5) Daim Ntawv Thov: Cov khoom siv sab hauv tsev / sab nraum zoov (cov txee, khoom siv), cov khoom siv kho kom zoo nkauj, me me corrosive ib puag ncig.
(6) Nqi: Tsawg mus rau nruab nrab (tus nqi-zoo rau ntau lawm).
3. Ua kua pleev xim
(1) Txoj Cai: Txau- siv cov kuab tshuaj- raws li cov xim (acrylic, polyurethane, thiab lwm yam), cua- lossis qhov cub- kho.
(2) Corrosion Resistance: Nruab nrab; yuav tsum tau primer (xws li, epoxy + polyurethane topcoat) rau kev tiv thaiv zoo dua.
(3) Cov tsos: Kho gloss (siab-gloss/matte), tab sis nws yooj yim rau drips thiab txiv kab ntxwv-peel kev ntxhib los mos.
(4) Hardness: Tsawg (kos tau yooj yim), xav tau kev saib xyuas ib ntus.
(5) Daim Ntawv Thov: Cov qauv ib ntus, sab hauv tsev décor, qis - kev tiv thaiv kev siv nyiaj txiag.
(6) Nqi: Tsawg (tab sis ntev dua -cov nqi tu lub sij hawm).
