1.What yog qhov zoo ntawm cov hlau galvanized piv rau cov xim - coated steel?
Qhov zoo ntawm cov xim xim - coated txheej hlau: nws cov intrated xim txheej (xws li lub ru tsev sab nrauv) tsis muaj qhov xav tau ntawm cov duab txuas ntxiv.
Cov txiaj ntsig zoo ntawm Galvanized steel (muaj peev xwm ntau dua. Cov txheej txheem organic ntawm cov xim - coated steel yog nquag mus tawg thiab ncab thaum lub qhov rooj sib sib zog nqus thiab ncab (xws li lub qhov rooj sib sib zog nqus ntawm lub qhov rooj tsheb sib sib zog nqus). Hauv kev sib piv, cov txheej zinc txheej ntawm cov hlau galvanized muaj qhov sib txuam ntawm cov steeling thiab sib npaug, zoo li cov khoom siv hluav taws xob ntau dua lossis cov ntaub pua chaw ua haujlwm).
2.What yog qhov zoo ntawm cov hlau galvanized piv rau galvanized steel?
Qhov zoo ntawm Galvanized steelized: zoo dua siab high - tsis kam (tuaj yeem tiv thaiv kub siab tshaj 300 degree, haum rau qhov cub hnab qhwv);
Qhov zoo ntawm cov hlau galvanized: galvanized steel vuam yooj yim ntau dua cov khoom siv tau yooj yim " Galvanized steel vuam (tshwj xeeb tshaj yog kub- dhuav lub zog (piv txwv li ntawm lub zog weld
3.Qhov yog qhov "dav dav zoo" ntawm Galvanized steel nws tus kheej?
Kev kho cov qauv nto: Cov qauv saum npoo (zoo li spangle, tsis muaj kev sib ntsib ntawm lub tshuab hluav taws xob ua kom tiav thiab sib npaug ntawm-}}}}}}} kev xav tau ntawm architural txhawb kev txhawb nqa.
Zoo vuam thiab pleev xim sib xyaw: Galvanized steel chaw tuaj yeem raug hla (chromate / chromate {{free) {free} free {} Pub dawb (tsis muaj roj av yooj yim. Qhov no txhim kho cov xim txuas ntxiv adhesion (15%-20% siab dua cov hlau decir) thiab txo cov xim tsis meej (xws li pinholes).
Lub zog - Cov Khoom Siv Yooj Yim: DX54D, piv txwv li ntau dua lossis muaj kev sib luag rau ntau dua lossis sib npaug ntawm 38%. Qhov no ua kom pom tseeb ob lub zog (xws li kev sib tsoo tiv thaiv kev sib tsoo ntawm lub cev tsheb) thiab muaj kev sib sib zog nqus kom muaj zog ntawm lub zog thiab ua haujlwm.
4.What yog qhov zoo ntawm cov hlau galvanized piv rau "uncoated yooj yim steel" (txias} rolled steel, kub} rolled steel)?
Mob khaub thuas zoo tib yam - rolled steel thiab kub {1} {rolled steel yog tsuas yog dov thiab tsis muaj kev tiv thaiv txheej ntawm saum npoo. Lawv qhov loj tshaj plaws yog xeb. Galvanized steel daws cov mob tseem ceeb no tseem ceeb ntawm "zinc txheej tiv thaiv".
Galvanized steel yog tsis tshua muaj corrosion - tsis kam: cov txheej sib xyaw "kev tiv thaiv anodic" (kev tiv thaiv lub substrate). Tsis tas li ntawd, zinc oxidizes los ua cov yeeb yaj kiab dense oxide (zno, zn (Oh) ₂), uas cais nws los ntawm dej thiab oxygen. Nyob rau hauv ib puag ncig ib puag ncig, nws lub neej yog 3 {4-}}} ntev dua li tias ntawm cov hlau dog dig, thiab nws-icing cov neeg sawv cev (ntsev), thiab hmoov av.
Tus txij nkawm tsawg: Tsis muaj qhov xav tau rau ntau qhov kev tawm tsam thiab xeb, thiab cov nqi tom ntej yog tsuas yog 1 / 3-1 / 2 ntawm cov hlau dog dig.
5.Qhov twg yog tus tseem ceeb ntawm galvanized steel?
Nws yog ntau dua corrosion - tsis kam tshaj li cov hlau decond, hais txog qhov mob ntawm qhov xeb ntawm xeb;
Nws yog pheej yig dua li stainless hlau, txo tus nqi pressures;
Nws yooj yim dua rau cov txheej txheem dua li xim - coated steel thiab galvanized steel thiab adapting rau cov kev tsim nyog ua.
Raws li qhov tshwm sim, nws tau siv dav hauv tsheb (lub cev thiab chassis), ua rau muaj cov hlau thiab tshuab (tsev nyob)
