1.Dab tsi yog qhov xwm txheej thiab kev ua haujlwm ntawm cov txheej txheem passivation?
Nws yog dab tsi? Ib txheej txheej passivation yog ib qho nyias nyias (feem ntau tsuas yog kaum mus rau pua pua nanometers) tuab oxide zaj duab xis los yog cov zaj duab xis sib xyaw ua rau ntawm qhov chaw ntawm zinc-plated txheej los ntawm kev kho tshuaj. Cov yeeb yaj kiab no feem ntau yog tsim los ntawm trivalent chromium compounds, chromium-dawb organic-inorganic compounds, lossis lwm yam khoom.
Core Functions:
Kev Tiv Thaiv Kab Xev Dawb: Nws lub luag haujlwm tseem ceeb yog cais cov zinc txheej los ntawm cov dej noo thiab cov pa oxygen hauv huab cua, tiv thaiv zinc los ntawm cov tshuaj tiv thaiv los ua "dawb xeb" (piv txwv li zinc carbonate).
Txheej Adhesion Txhim Kho: Nws muab kev ruaj khov thiab kev sib koom ua ke rau kev pleev xim tom ntej thiab lwm yam txheej txheem.
Anti-Ntiv tes: Qee yam kev kho mob passivation (tiv thaiv- kev kho tus ntiv tes) tuaj yeem txo cov ntiv tes los ntawm hws thaum ua haujlwm.
2.Vim li cas nws tsis tiv taus kev sib txhuam?
Nyias heev: Muab piv rau cov txheej zinc hauv qab (feem ntau yog ob peb microns txog kaum microns), cov txheej txheej passivation yuav luag tsis pom zoo. Txawm tias qhov khawb me ntsis tuaj yeem ua rau nws puas.
Tsawg Hardness: Cov zaj duab xis passivation nws tus kheej muaj qhov tsis tshua muaj zog, qis dua li cov khoom siv abrasive xws li cov cuab yeej hlau thiab cov xuab zeb.
Thaum cov txheej txheej passivation raug hnav, lub hauv paus zinc txheej raug nthuav tawm. Qhov no tuaj yeem ua rau:
Degraded Corrosion Resistance: Cov txheej txheej zinc nthuav tawm, tsis muaj kev tiv thaiv ntawm cov yeeb yaj kiab passivation, muaj kev cuam tshuam ntau dua rau cov xeb dawb hauv qhov chaw ntub dej.
Cov tsos mob tshwm sim: Qhov chaw rub tawm tuaj yeem pom ci, tsaus, lossis tsis sib haum nrog cov xim ib puag ncig, cuam tshuam rau nws qhov zoo nkauj.
3.Dab tsi yog txoj kev sib txhuam tsis sib haum?
RCA Daim Kab Xev Abrasion Tester: Daim ntawv daim kab xev yog rov ua dua tawm tsam tus qauv ntawm qhov chaw tshwj xeeb kom txog rau thaum txheej txheej passivation tau hnav los ntawm (qhov no tuaj yeem txiav txim siab los ntawm kev saib xyuas qhov kev hloov pauv lossis saib xyuas cov tsos). Qhov ntau dua cov rubs, qhov zoo dua qhov kev puas tsuaj.
Cawv Sov Rhaub Test: Ib qho dej cawv so yog rub rov qab thiab tawm ntawm qhov chaw ntawm lub siab tshwj xeeb, thiab cov sij hawm nws yuav siv sij hawm rau cov cim coj los tshwm. Qhov no yog ib txoj hauv kev yooj yim dua uas ze dua rau kev ua haujlwm tiag tiag.
4.Dab tsi yog txoj hauv kev los txhim kho kev sib txhuam?
Xaiv qhov kev kho kom ruaj khov dua:
Roj txheej: Siv cov txheej nyias nyias ntawm xeb- cov roj pov thawj rau cov txheej txheem passivation tuaj yeem txhim kho luv luv - lub sij hawm kev sib txhuam thiab xeb kuj. Cov roj zaj duab xis ua raws li cov roj nplaum thiab ib qho kev thaiv ntxiv. Qhov no yog txoj hauv kev zoo tshaj plaws thiab kev lag luam.
Anti-kev kho tus ntiv tes: Qhov no yog ib qho tshwj xeeb chrome-dawb passivation uas feem ntau tsim cov thicker, denser, organic-inorganic composite zaj duab xis nrog rau qib ntawm tus kheej- lubrication. Nws cov kev sib txhuam thiab cov ntiv tes tiv thaiv yog qhov zoo dua li cov txheej txheem passivation, ua rau nws siv dav hauv cov ntawv thov xws li cov khoom siv hauv tsev thiab cov rooj plaub hauv computer uas yuav tsum tau ua tom ntej thiab ua kom zoo li qub.
Painting / Laminating: Qhov no yog qhov kev daws teeb meem zoo tshaj plaws. Siv cov txheej txheem organic (PVDF, PE, thiab lwm yam) los yog siv PVC zaj duab xis rau cov galvanized coil tsim ib txheej tuab, tawv tawv. Qhov no tsis tsuas yog muab kev sib txhuam zoo heev, tab sis kuj muaj ntau yam xim thiab qauv, nrog rau kev txhim kho corrosion kuj.
5.Yuav ua li cas los txhim kho kev ua haujlwm thiab kev ua haujlwm ib puag ncig?
Siv cov chais du thiab cov kev taw qhia ntawm cov kab ntau lawm kom tsis txhob muaj kab mob nrog cov khoom tawv xws li vuam slag thiab hlau filings.
Siv spacers thaum tuav thiab stacking los tiv thaiv hlau -rau -hlau kov.
Khaws lub rooj cob qhia kom huv si thiab txo cov plua plav thiab cov khoom me me.
