Kev daws qhov tsis zoo ntawm cov cuab yeej siv tshuab thiab tshuaj lom neeg ua haujlwm
1. Cov khoom siv tsis zoo thiab tshuaj lom neeg tsis zoo
Ua rau: siab dhau los yog qis qis kho kub lossis lub sijhawm
tshuaj: Paub meej thiab kos nrog hmoov txheej hmoov khoom
Cause:Roj, roj, roj extrusion, hmoov av ntawm qhov chaw
Kev daws: Optimize pretreatment
Ua rau: Cov khoom sib txawv thiab cov khoom siv xim
Kev daws: Tsis txaus pretreatment
Ua rau: Incompatible pretreatment thiab hmoov txheej
Kev daws: Kho cov txheej txheem pretreatment, sab laj cov khoom siv hmoov
2.Greasy Surface (Haze zoo li zaj duab xis ntawm qhov chaw uas tuaj yeem so tawm)
Ua rau: Blooming nyhuv-dawb zaj duab xis rau ntawm cov hmoov av, uas tuaj yeem wiped tawm
Kev daws: Hloov cov hmoov txheej txheej, ua kom kub kub
Ua rau: Cov cua tsis txaus hauv qhov cub
Kev daws: Ua kom huab cua ncig
Ua rau: Kev sib kis ntawm qhov chaw vim tsis sib haum ntawm cov hmoov txheej
Kev daws: Siv tsuas yog hmoov txheej los ntawm ib tus neeg muag khoom.
Ua rau: hmoov txheej tsis txaus kho
Kev daws: Saib xyuas qhov ntsuas qhov ntsuas
3.Kev nqa cov hmoov txheej txheej
Ua rau: Hauv qab lossis dhau kev kho ntawm cov hmoov txheej zaj duab xis
Kev daws: Saib xyuas qhov ntsuas qhov ntsuas
Ua rau: Tsis txaus / tsis tsim nyog pretreatment
Kev daws: Kho pretreatment rau txoj hauj lwm ntawm tes
Ua rau: Scale, nto xeb ntawm cov khoom ua haujlwm
Kev daws: Siv cov khoom ua haujlwm "tshiab" lossis khaws cia hauv qhov chaw qhuav; kev kho tshuab ua ntej
Ua rau: Oxide txheej ntawm cov khoom ua haujlwm, dawb xeb ntawm zinc palting
Kev daws: Siv cov khoom siv ua ntej tsim nyog; Siv cov khoom ua ntej ua ntej
Ua rau: Txo cov yeeb yaj kiab thickness lossis siv ntau dua
4.Poor Mechanical Properties -Txoj kev cuam tshuam tsis zoo lossis tsis yooj yim
Ua rau: Nyob rau hauv curing ntawm txheej zaj duab xis
Kev daws: Optimize curing parameters
Ua rau: ntxuav tsis zoo los yog preteatment
Kev daws: Xyuas pretreatment thiab txheej txheem
Ua rau: Zaj duab xis thickness siab dhau
Kev daws: Optimize lub thickness ntawm zaj duab xis
Ua rau: Cov khoom tsis zoo ntawm cov khoom siv hmoov txheej / resin
Kev daws: Tham nrog tus neeg muag khoom hmoov
