Corrosion tuaj yeem muab faib ua cov tshuaj corrosion thiab electrochemical corrosion

Hnav Cov Khoom Siv Slurry Tawb Chaw Tsim Tshuaj Qhov Chaw Tsim Tshuaj Kev Tsim Khoom Siv Hluav Taws Xob, thiab cov khoom sib txawv ntawm cov khoom lag luam tsis zoo li cas, tab sis feem ntau tuaj yeem suav tau hauv peb pawg:

1 Yis: Hauv cov slurry tso kua mis chaw tsim tshuaj paus thaum lub sijhawm ua haujlwm, cov kua rau cov khoom ntws nyob rau hauv tus neeg txaus ntawm cov neeg muaj feem, ua rau cov khoom poob. Raws li kev tshuaj ntsuam ntawm qhov tsis ua haujlwm ntawm kev coj hnav cov hlua saum npoo uas tuaj yeem faib ua kev hnav thiab qaug zog hnav ntawm kev txiav + sib xyaw.

2 Cavitation puas tsuaj: thaum lub sijhawm ua haujlwm ntawm cov twj tso kua mis, feem ntau yog nyob rau hauv lub sijhawm tom qab), rau qee qhov ua kua rau thaum lub sijhawm kub, ntawm qhov twg Cov kua tau pib vaporized los tsim cov chav, kev tsim cov npuas. Cov npuas no nrog cov kua ntws rau pem hauv ntej, nce mus txog lub siab dua, npuas vaurapse txo qis tsis tau txawm tias. Lub caij no nyob rau hauv lub bubble, cov kua hais ntawm qhov kev kub ceev sau voids, thiab muaj qhov cuam tshuam zoo ntawm cov hlau nto. Qhov no hlau saum toj vim kev cuam tshuam ntawm kev qaug zog, ua rau cov khoom poob poob, hlau nto sib txawv qhia honeycomb. Qhov chaw ntawm cavitation feem ntau tshwm sim hauv qhov hluav taws xob cuam tshuam thiab qhov hluav taws xob hauv.

3 Corrosive Hnav: Thaum cov kis tau tus kis tau muaj qee yam pH,Slurry Cov Twj Tso Kua MuagFlow Cheebtsam yuav tshwm sim Corrosive kev hnav, uas yog poob ntawm cov khoom tshwm sim nyob rau hauv kev ua ke ntawm corrosion thiab hnav.

Corrosion tuaj yeem muab faib ua cov tshuaj corrosion thiab electrochemical corrosion. Tshuaj lom neeg corrosion thiab kua tub ceev xwm ncaj qha tawm cov hlau tsis ua haujlwm, hluav taws xob corrosion yog lub luag haujlwm ntawm cov hlau nto los ua cov micro- roj teeb tawm hauv cov khoom poob. Txij li kev siv cov khoom siv hlau yog cov ntaub ntawv multiphase polycrystalline, tshwj xeeb yog cais cov khoom sib xyaw hlau, thiab cais cov khoom nyuaj, ploj mus, yog li nws yuav tawm nyob rau hauv lub yaig tshwm sim khoom me me; Thaum nplawm cov khoom siv khov kho, thiab cov hlau saum npoo av vim yog cov khoom sib nug ua kua rau hauv kev sib cuag nrog cov hlau saum npoo los ua kom muaj zog ntxiv. Slrry nqus nqus cov chaw tsim khoom hauv qhov tsis ua tiav tsom ntawm lub neej ntawm qhov tshwm sim ntawm qhov tshwm sim tau pom muaj corrosion.
