Cov pa roj carbon steel raj muaj cov hlau thiab carbon alloy uas tuaj yeem khoov rau hauv cov duab thaum lub sijhawm tsim khoom yam tsis txo nws lub zog tensile siab. Nws yog ib qho tseem ceeb los tiv thaiv cov hlau nto los ntawm corrosion vim hlau ferrite muaj pes tsawg leeg uas yuav xeb los ntawm oxidization los ntawm dej sib cuag. Cov kav dej uas muab cov tshuab tua hluav taws feem ntau yog cov pa roj carbon steel, thiab cov khoom siv muaj zog xws li cam thiab crankshafts hauv cov dav hlau thiab tsheb siv cov pa roj carbon steel tubing. Painting carbon steel hlab kom zoo tsis txhob xeb yuav tsum tau siv cov primer kom raug thiab xim.
carbon steel tube painting
1. Siv hlau wool thiab tshem tawm tag nrho cov nto xeb los ntawm carbon steel raj. cheb txhua yam xeb uas siv cov txhuam hniav kom qhov chaw ua haujlwm kom tsis txhob muaj plua plav.
2. Siv cov kuab tshuaj ntxuav tes thiab ib daim ntaub los txhuam cov roj thiab cov roj stains los ntawm qhov chaw ntawm cov yeeb nkab. So daim ntaub hla tag nrho saum npoo ntawm cov yeeb nkab kom khaws cov plua plav lossis xeb uas nyob twj ywm. Cia cov pa roj carbon steel kom qhuav.
3. Qhib cov zinc phosphate xim primer thiab siv cov nplaum nplaum los sib tov cov primer kom sib xws. Siv zinc phosphate xim primer vim zinc tsim ib qho kev thaiv uas ua raws li anode hauv cov txheej txheem electrochemical corrosion thiab deflects pitting ntawm cov hlau.
4. Muab cov primer tso rau hauv cov xim pleev xim thiab siv lub tsho tuab rau cov yeeb nkab carbon steel. Cia cov primer kom qhuav raws li cov neeg tsim khoom cov lus qhia.
5. Siv cov nplaum nplaum thiab sib tov cov xim polyurethane acrylic kom xim homogeneous. Siv cov txhuam hniav thiab siv cov xim pleev xim rau ntawm cov yeeb nkab. So txhua cov xim uas nkag mus rau qhov kawg ntawm cov pa roj carbon steel yeeb nkab uas tsis tau txuas ntxiv txhawm rau tiv thaiv cov yeeb nkab sib kis.
6. Cia thawj lub tsho tiv no ntawm cov xim kom qhuav raws li cov neeg tsim khoom cov lus qhia. Feem ntau, feem ntau cov xim acrylic yog npaj rau lub tsho tiv no tom qab ob teev. Xim lub tsho tiv no zaum kawg ntawm polyurethane acrylic rau saum npoo ntawm cov yeeb nkab carbon steel kom ua tiav txoj haujlwm.
Vim qhov kev xav tau ntawm kev lag luam, api carbon seamless yeeb nkab yuav tsum tsis tsuas yog them sai sai rau qhov du thiab ci ntsa iab, tab sis kuj xyuam xim rau kev tiv thaiv sab hauv. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm painting, yuav tsum tau nqa tawm kev soj ntsuam zoo, thiab lub sij hawm yuav tsum tau tswj kom zoo.
