1.How yog qhov kev siv corrosion ntawm kev siv ib puag ncig txiav txim siab txog qhov hnyav?
Cov ntsev ua xeb ib puag ncig, xws li thaj chaw ntug dej hiav txwv (cov cheeb tsam txias (kev siv khoom noj khoom haus (Sulfide / Plua Tawv (Sulfide / Hmoov Piv txwv li, cov chassis thiab qhov rooj sassis thiab qhov rooj hauv cov tsheb hauv cov ntug hiav txwv feem ntau yuav tsum muaj zinc / m² (ob sab, tib yam siv hauv qab). Qee qhov chaw ib puag ncig huab tseem xav tau 120-180g / m².
Cov cheeb tsam qis, xws li cov chaw nyob hauv thaj chaw thiab cov chaw hauv nroog tsis muaj kev pheej hmoo, muaj cov phom sij qis dua thiab tuaj yeem xav tau cov txheej nyias nyias nyias; Feem ntau, 50-80g / m² yog txaus.
2.different Cheebtsam muaj cov kev pheej hmoo corrosion sib txawv. Yuav xaiv li cas?
Cov chaw pheej hmoo siab: Cheebtsam zoo ncaj qha rau cov av nkos, dej, thiab ntsev, thiab ntsev ntev, thiab roj tank nkhaus. Cov chaw no muaj kev cuam tshuam av nkos, dej, cov ntsev melting ntsev, thiab cov xuab zeb thiab gravel, thiab nthuav tawm cov kev pheej hmoo siab tshaj plaws. Lawv yuav tsum muaj cov txheej txheej tuab (feem ntau 80-150G / M²). Nyob rau hauv cov neeg mob hnyav (xws li kev lag luam tsheb chassis), cov xim ua tau ntau dua 200g / m².
Nruab nrab-qhov txaus ntshai thaj chaw: sab nrauv lub cev panels (qhov rooj, hood, ru tsev, ru tsev, thiab lwm yam). Txawm hais tias raug rau cov ntsiab lus, lawv feem ntau pleev xim (Primer + Topcoat) thiab nthuav tawm cov kev pheej hmoo qis dua li Chassis. Cov txheej yuav tsum sib npaug tiv thaiv nrog cov xim nplaum, feem ntau xaiv 60-90g / m² (ntau dhau thickness yuav cuam tshuam txheej adstion).
Tsawg txoj kev pheej hmoo: sab hauv cov txheej txheem sab hauv (xws li cov ncej thiab sab hauv ntawm crossbeams) thiab tsis raug nyob rau hauv lub cav compartment. Cov chaw no ua haujlwm nyob rau hauv cov chaw paug tsis txaus, thiab siv cov txheej txheem thia (40-60g / m²).
3.Yuav ua li cas ua qhov sib txawv ntawm corrosion ntawm cov hom zinc cuam cuam tshuam rau kev xaiv kom yuag?
Cov ntshiab zinc txheej: corrosion tsis yog nyob ntawm feem ntau ntawm cov tuab ntawm zinc txheej ntawm zinc txheej ntawm zinc txheej ntawm zinc txheej, kom ua kom hnyav tuaj yeem txhim kho kev tiv thaiv.
Alloy txheej: Vim tias muaj kev cuam tshuam txhim kho corrosion tsis kam, qhov hnyav qis dua tuaj yeem siv rau tib yam kev tsim kho corrosion. Piv txwv li, zinc-nickel alloy txheej txheem muaj 3-5 zaug lub corrosion tsis kam ntawm cov ntsev ntshiab hauv cov ntsev. Rau qee thaj chaw muaj kev pheej hmoo siab, qhov hnyav txheej ntawm 60ur00G / m² tuaj yeem hloov lub 120g / m² ntawm ntshiab zinc.
4.What yog cov kev yuav tsum tau ua thiab tha xim ua ntej?
Cov txheej txheem: cov txheej tuab tuab yuav ua rau txheej peeling lossis tawg thaum thaum lub sijhawm stamping thiab dabtsi yog khoov. Qhov no yog qhov tseeb tshwj xeeb rau cov khoom uas muaj ntau yam li cov vaj huam sib luag sab hauv). Lub cev yuag yuag yuav tsum tau tswj kom ntseeg tau cov txheej txheem (feem ntau tsawg dua lossis sib npaug rau 100g / m²).
Txheej Txheej Ntau: Yog tias qhov yuav tsum tau ua kom lub cev tom qab (txo cov txheej txheem sab nrauv), txo cov txheej txheem sib txuam (txo cov txheej txheem sib txuam Ib qho nyiaj tshuav yuav tsum tau tsim ntawm corrosion tsis kam thiab txheej ua tau zoo. Ib txheej hnyav ntawm 60-90G / m² feem ntau xaiv.
5.Qhov yog xaiv log?
Los ntawm ib puag ncig kev sib koom ua: muaj kev kub siab (cov ntug dej hiav txwv / chaw nyob) → tuab txheej txheej (100-180g / m²); Tsawg txoj kev xeb (thaj chaw hauv thaj chaw qhuav) → yuag cov txheej (40-810g / m²).
Los ntawm cov kev pheej hmoo tiv thaiv: kev pheej hmoo siab xws li chassis / sills → tuab txheej txheej; Panels sab nrauv / sab hauv cov txheej txheem sab hauv → nruab nrab me me.
Sib tov txheej: alloy txheej (zinc-nickel / zinc-hlau) tuaj yeem txo qhov hnyav; Ntshiab Zinc Txheej Txheem yuav tsum muaj qhov hnyav dua.
Sib npaug ntawm cov txheej txheem thiab tus nqi: Zam kev ua kom ntau dhau uas yuav cuam tshuam rau kev ua kom corrosion tsawg kawg nkaus uas yuav tsum muaj rau lub neej tsim.
