1. Cov plua plav cuam tshuam li cas rau cov txheej txheem?
Lub cev Scratches (Qhov tseem ceeb tshaj plaws thiab feem ntau txaus ntshai)
Abrasive Effects: Hlau hais thiab sib tsoo log khib nyiab tsim thaum txiav, drilling, thiab sawing txheej txheem nyuaj dua li cov organic txheej ntawm cov xim -coated steel ntawv. Yog tias cov plua plav tawv no tseem nyob ntawm qhov chaw, lawv yuav khawb cov txheej txheej zoo li cov ntawv xuab zeb thaum tuav tom ntej, stacking, thiab kev sib txhuam, tsim kom zoo khawb.
Cov txiaj ntsig: Ua rau cov txheej txheej gloss thiab smoothness, cuam tshuam rau kev zoo nkauj. Ntau qhov tseeb, yog tias khawb tob txaus kom nthuav tawm cov hlau substrate, lawv yuav tsim cov ntsiab lus corrosion pib, ua rau cov ntawv luv luv.
Tshuaj Corrosion
Active Hlau Plua Plav: Plua plav tsim thaum lub sij hawm txiav ntawm txhuas -magnesium alloys los yog lwm yam hlau, yog adhering rau saum npoo ntawm cov xim -coated steel ntawv, tej zaum yuav ua rau "galvanic corrosion" nyob rau hauv ib puag ncig ntub. Cov khoom siv hlau plua plav no tsim cov galvanic hlwb nrog cov hlau substrate, ua kom corrosion ntawm qhov txiav lossis khawb ntawm cov xim -coated steel ntawv.
Corrosive Substances: Cov plua plav hauv qee qhov chaw ua haujlwm yuav muaj cov tshuaj xws li acids, alkalis, thiab ntsev, uas tuaj yeem cuam tshuam ncaj qha rau txheej txheej.
Kev cuam tshuam rau cov txheej txheem tom ntej thiab kev ua haujlwm
Teeb meem adhesion: Yog tias cov plua plav seem tseem nyob rau ntawm lub rooj tsavxwm, nws yuav ua rau muaj kev cuam tshuam loj ntawm cov nplaum nplaum los yog kho cov xim thaum lub sij hawm ntawm - qhov chaw tshuaj tsuag los yog sealing, ua rau blistering thiab tev tawm.
Sealing Failure: Thaum lub sij hawm installation, hmoov av ntawm cov pob qij txha los yog overlaps yuav tiv thaiv lub sealant strips los yog sealant los ntawm tag nrho adhering rau lub board nto, uas ua rau dej thiab huab cua.
2.Dab tsi yog qhov kev pheej hmoo siab - cov txheej txheem thiab cov kauj ruam?
Txiav: Cov nplaim taws thiab siab - kub molten hlau particles generated los ntawm abrasive log txiav (lub kaum sab xis grinder) tau yooj yim embed nyob rau hauv thiab hlawv coatings.
Sawing: Band saws thiab ncig saws tsim ntau cov hlau shavings thiab abrasive hais.
Drilling: Ua cov kauv- zoo li cov hlau shavings nrog cov npoo ntse.
Sib tsoo / Trimming: ncaj qha ua kom muaj cov hmoov av abrasive thiab hlau sib xyaw, ua rau muaj kuab paug rau thaj tsam ib puag ncig.
3.Dab tsi yog qee qhov tsawg- pheej hmoo tab sis cov txheej txheem ceev faj?
Shearing: Cov txiaj ntsig zoo hlau shavings tuaj yeem khawb qhov saum npoo ntawm daim ntawv.
Khoov / dov: Cov txheej txheem no feem ntau tsis tsim cov plua plav ncaj qha, tab sis cov kab mob ntawm cov chais tuaj yeem nkag mus rau daim ntawv.
4.Yuav tiv thaiv nws thaum ua haujlwm li cas?
Kev tiv thaiv zaj duab xis tshem tawm cov tswv yim: ncua sij hawm tshem tawm cov yeeb yaj kiab tiv thaiv los ntawm qhov chaw ntawm cov xim -coated yob ntau li ntau tau kom txog thaum thaj chaw tiav. Cov yeeb yaj kiab tiv thaiv yog thawj kab ntawm kev tiv thaiv kev khawb.
Kev Tu Sijhawm: Tam sim ntawd tom qab txhua txoj kev, siv daim ntaub huv, qhuav, txhuam mos, lossis rab phom cua kom tshem tawm cov plua plav thiab cov khib nyiab ntawm qhov chaw thiab ib puag ncig.
Tool thiab Workbench Cleaning: Khaws cov chaw ua haujlwm, coj cov ntsia hlau, cov khoom siv, thiab cov cuab yeej huv si kom tiv thaiv kev sib kis -.
5.Dab tsi yog lub hauv paus ntsiab lus thiab cov lus qhia rau kev tuav thiab stacking?
Kov nrog kev saib xyuas thiab tsis txhob rub: rub cov laug cam yuav ua rau cov plua plav tawm hauv qab mus rau "sib tsoo" ntawm qhov chaw.
Siv cov ntoo huv si thiab cov khoom sib txuas: xyuas kom meej tias cov kev txhawb nqa huv si thiab tsis muaj cov khoom tawv thaum sib tsoo.
Kev tiv thaiv cov khoom tiav: Npog cov khoom tiav nrog cov ntaub ntawv tiv thaiv lossis cov yeeb yaj kiab yas kom sai kom tsis txhob muaj plua plav paug ntawm ib puag ncig.
