Dab tsi yog cov haujlwm ntawm passivation hauv electrogalvanizing ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj?

① Txhim kho corrosion kuj ntawm galvanized txheej

② Ua kom lub ntsej muag tsis yooj yim kom muaj kuab paug los ntawm lwm tus

③ Ua kom lub zog sib txuas ntawm cov txheej tom ntej

④ Tau txais cov nyhuv zoo nkauj

Functionality ntawm lub tshuab nqus tsev plating hluav taws xob cua sov tube txheej

Cov txheej txheej electro-galvanized yuav tsum ua tau raws li nws cov kev xav tau, suav nrog tsis muaj hydrogen embrittlement, adhesion yuav tsum tau thiab corrosion kuj yuav tsum tau.

Cov ntaub ntawv siv rau lub tshuab nqus tsev electroplating hluav taws xob cua sov raj polishing log

Cov ntaub ntawv siv los ua polishing log muaj xws li ntau yam paj rwb ntaub, zoo zoo, tawv, thiab lwm yam. Cov ntaub log ua los ntawm cov ntawv tshwj xeeb uas twb muaj lawm (xws li liab ntoo thuv pulp crepe ntawv) kuj tau siv dav. Lub hardness ntawm polishing log yog txiav txim los ntawm qhov kev ncua deb ntawm txoj kab suture. Qhov me me qhov kev ncua deb ntawm txoj kab suture, qhov hardness ntawm polishing log ntau dua. Tsis tas li ntawd, lub hardness kuj muaj feem xyuam rau hom polishing log ntaub.

Lub hom phiaj ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj polishing

Polishing feem ntau yog siv rau kev ua tiav ntawm txheej tom qab plating, thiab nws kuj tseem siv tau rau kev ua ntej ntawm cov khoom ua ntej plating. Nws yog nqa tawm ntawm lub tshuab polishing, uas yog nruab nrog lub log polishing. Lub hom phiaj ntawm polishing yog txhawm rau txhim kho qhov smoothness ntawm cov khoom, kom cov khoom tuaj yeem tau txais cov khoom zoo nkauj; txhim kho corrosion kuj ntawm cov khoom; ntxiv tshem tawm qhov hloov maj mam unevenness ntawm qhov chaw ntawm cov khoom.

Hais txog lub hauv paus ntsiab lus ntawm polishing, nws yog feem ntau ntseeg hais tias thaum lub polishing log rotates ntawm ib tug ceev ceev, kev sib txhuam ntawm lub workpiece thiab daim ntaub log generates kub, uas yog qhov nce ntawm plasticity ntawm cov hlau. Nyob rau hauv qhov kev txiav txim ntawm polishing quab yuam, cov hlau nto yog plastically deformed, thiab qhov convex yog nias nyob rau hauv. Thiab ntws, lub concave ib feem yog sau, thiaj li hais tias qhov zoo uneven nto yog ntxiv txhim kho. Nyob rau tib lub sijhawm, cov tshuaj muaj pes tsawg leeg ntawm polishing muab tshuaj txhuam thiab ib puag ncig nruab nrab thaum polishing kuj ua lub luag haujlwm. Thaum lub sij hawm polishing txheej txheem, cov hlau feem ntau muaj cov tshuaj tiv thaiv ib puag ncig, uas cuam tshuam rau polishing ceev. Piv txwv li, polishing ceev yog txo nyob rau hauv hydrogen nruab nrab; polishing ceev yog ceev nyob rau hauv hydrogen sulfide roj.
