Q: Yuav ua li cas kom txo cov npoo roughness los ntawm kev ua kom zoo dua cov txheej txheem?
A: Xaiv cov neeg sawv cev me thiab ruaj khov
Teeb meem nrog cov txheej txheem tsoos: muaj zog alkaline depents (xws li sodium hydroxide) yuav ua rau me ntsis corrosion rau lub substrate mus rau substrate, sib sau microscopic ntxig saum .
Kev daws teeb meem zoo: ◦ Siv tsis muaj zog alkaline cov neeg sawv cev (xws li sodium carbonate + surfactant tus neeg sawv cev (xws li emulsifiers) los yog ne rill corrosion ntawm cov hlau saum npoo npoo.
Rau cov oily workpieces, ultrasonic degreing tuaj yeem siv los txhim kho cov roj tshem tawm los ntawm cavitation nyhuv thiab tsis txhob khawb saum npoo los ntawm cov neeg kho tshuab txhuam .
Cov nyhuv: degreasing yog ntau yam tsis zoo thiab meej, tsis txhob muaj cov roj txuas ntxiv vim tias cov roj rov qab roughness .
Q: Cov txheej txheem binnling tau ua kom zoo dua los txo cov roughness?
A: Siv cov kua qaub sib xyaw los yog ntxiv corrosion inhibitor:
Hydrochloric acid + hydrofluoric acid (HF) sib xyaw acid: HF tuaj yeem tshem cov pob zeb silical, thiab txo qis corrosion hauv zos.
Ntxiv cov organic corrosion inhibitors (xws li thiourceas, inhibit ntau dhau ntawm cov kua qaub, thiab txo cov roj ntsha, thiab txo cov tawv nqaij ntawm 30% ~ 50%.
Hloov mus rau phosphoric acid los yog aminosulfonic acid:
Phosphoric acid tau ua rau me ntsis acidity thiab tsawg. nws tuaj yeem tsim cov txiaj ntsig kev hloov pauv ntawm galvanized txheej .
Aminosulfonic Acid yog tsis yog-tsim nyog rau pickling ntawm chav tsev kub kom txo tau ntau dhau mus etching.
Q: Yuav ua li cas kom txo qhov kev puas tsuaj saum npoo?
A: {{1.} Tsis txhob muaj lossis hloov cov sandblasting / txhaj tshuaj blasting
Tsuas yog rau kev ua haujlwm kom tsawg xeb: Yog tias nws yuav tsum tau siv, siv dej khov lossis qhuav dej kub ntawm 0}} 2 ~ 0.4mpa kom txo qis qhov tob ntawm lub pits.
Tshuaj ntsuam xeb yog qhov nyiam: rau me me mus rau nruab nrab xeb, siv cov roj tawg lossis siv xeb (xws li tannic acid).
{{0 {}} tshuab sib tsoo thiab kho kom zoo
Yog tias kev sib tsoo yuav tsum muaj, siv cov xuab zeb uas muaj kev sib tsoo:
Kev sib tsoo txhav: 120 # ~ 240 # xuab zeb kom tshem cov burrs thiab prorcusions .
Fine grinding: 400#~800# sandpaper to refine the surface and reduce the roughness to Ra 1.6~3.2μm.
Q: Yuav ua li cas xaiv kev daws teeb meem?
A: Cov kua qaub tsis muaj zog: xws li 5% ~ 10% hydrochloric acid. Cov kua qaub ua kom muaj zog rau hauv 2 ~ 3 txhawm rau txo cov npoo theem nrab rau saum npoo .
Q: Cov ntsiab cai tseem ceeb ntawm kev ua tiav kev ua haujlwm zoo li cas?
A: {{1. Cov kev kho siab mos siab muag yog qhov xav tau cov txheej txheem, thiab siv cov tshuaj sib xyaw ua ke, thiab siv cov tshuaj muaj zog, thiab siv cov tshuaj txhuam cov txheej txheem es tsis txhob tawm ntawm cov tshuab tshem tawm .
2.} Kev Tswj Xyuas Kev Tswj Xyuas Cov Khoom Siv: Xyuas kom muaj kev daws teeb meem, kub thiab khoom siv (xws li cov cuab yeej siv hluav taws xob, hluav taws xob (xws li cov tshuab electrolacytic, {}
{{03.} Kev sib koom tes ua ke tsim: → Kev Tshuaj Tiv Thaiv (nrog corrosion → Kev Tshuaj Tiv Thaiv Tsis muaj zog los ua cov txheej txheem tsis muaj zog.
{4.} Ntsuas Tshawb Nrhiav Online: Siv cov ntsuas pa tawm los saib xyuas cov ntxhib tom qab thiab kho cov txheej txheem tsis xws li.
