Dab tsi yog coil txheej txheej txheem?
Cov txheej txheem txheej txheej rau PPGI (ua ntej {{0} Daim duab xim galvanized) los npaj thiab siv cov txheej txheem tiv thaiv thiab dai kom zoo nkauj:
1) Kev npaj saum npoo:
-}}}}}}}} cov hlau galvanized yog kom huv si kom tshem tawm cov av, roj, lossis cov paug. Qhov no feem ntau ua tiav siv kev sib txuas ntawm alkaline lossis acidic ntxuav.
- rinsing: Tom qab tu, saum npoo yog yaug los ua kom txhua seem raug tshem tawm.
2) Kev kho tshuaj lom neeg:
- phosphating lossis Chromating: Cov hlau tau kho nrog kev daws teeb meem hauv ntsev lossis chromate tebchaw. Qhov no ua ib qho nyias nyias, tshuaj - hloov dua siab tshiab rau saum npoo. Cov kauj ruam no txhim kho adhesion thiab muab cov tshuaj tiv thaiv ntxiv.
3) Daim ntawv thov Primer:
{{0-} Lub tsho tiv no primer yog thov rau cov npaj tseg. Qhov pib no tshwj xeeb tau tsim tshwj xeeb rau siv rau cov hlau galvanized thiab muab cov tshuaj nplaum rau cov khaubncaws sab nraud pov thawj.
4) Daim ntawv thov ntawm lub tsho tiv no sab saum toj:
- Lub tsho tiv no, uas muaj cov xim rau xim thiab cov khoom tiv thaiv ntxiv, yog thov. Ntau hom txheej txheej (polyester, SMP, PVDF, thiab lwm yam) yuav siv nyob ntawm qhov kev ua tau tshwj xeeb.
5) Kho lossis ci:
- Cov coated steel yog tom qab ntawd dhau los ntawm kev mob siab los yog ci txheej txheem. Qhov no solidifies thiab bonds cov txheej rau saum npoo ntawm cov hlau.
6) Txias thiab tshuaj xyuas:
{{0- Cov txheej txheem freshly tso tawm kom txias. Nws yog tom qab ntawd xyuas rau cov kev sib xyaw, adhesion, thiab cov peev xwm tsis xws luag.
7) Txheej ntxiv (yeem):
- Nyob ntawm qhov kev ua tshwj xeeb, lub tsho tiv no ntxiv, txheej tiv thaiv ntxiv yuav siv rau kev txhim kho kom tau durability lossis cov khoom tshwj xeeb.
8) Tej thiab ntim:
- Tom qab txheej txheem txheej txheej tiav, cov ppgi steel yog feem ntau txiav mus rau hauv coils lossis cov nplooj ntawv uas xav tau ntev thiab dav. Nws yog tom qab ntawd ntim rau kev cia khoom lossis cov zaub mov xa tuaj.
Nws yog tsim nyog sau cia tias cov ntsiab lus tseeb ntawm txheej txheem txheej txheej yuav sib txawv raws li cov chaw tsim khoom, cov qauv zoo nkauj ua kom zoo nkauj. Ib qho ntxiv, qee cov tuam ntxhab yuav muab cov kauj ruam ntxiv lossis kev kho tshwj xeeb rau cov ntawv thov tshwj xeeb lossis txhim kho kev ua tau zoo.
