daim ntawv thov
Kev lag luam roj thiab roj: Nws yog cov khoom siv tseem ceeb rau cov khoom siv tseem ceeb hauv kev tshawb nrhiav roj thiab roj, kev rho tawm thiab kev ua haujlwm. Nws feem ntau yog siv los ua cov hlab ntsha siab rau khaws cia thiab thauj cov roj thiab cov pa roj, cov khoom siv hluav taws xob uas siv cov khoom siv hluav taws xob hloov pauv ntawm cov roj thiab cov pa hluav taws xob, thiab cov khoom sib cais uas cais cov impurities thiab cov khoom sib txawv ntawm cov roj thiab roj. Cov khoom siv no yuav tsum tau tiv thaiv corrosion ntawm roj thiab roj thiab lub siab siab thaum lub sij hawm thauj mus los thiab ua, thiab qib steel no tuaj yeem ua tau raws li qhov xav tau.
Petrochemical & Tshuaj Kev Lag Luam: Hauv cov nroj tsuag petrochemical, nws yog dav siv los tsim cov reactors uas muaj kev cuam tshuam xws li tawg thiab hydrogenation ntawm cov khoom siv roj av, nrog rau cov tso tsheb hlau luam rau khaws cov khoom siv tshuaj corrosive lossis cov khoom tiav. Hauv cov chaw ua tshuaj, nws kuj tseem tsim nyog rau kev tsim lub tank kheej kheej rau kev khaws cia siab - cov khoom siv tshuaj lom neeg thiab siab - cov kav dej siab uas thauj cov kua tshuaj corrosive. Nws cov ntsiab lus chromium ua rau nws tiv thaiv corrosion los ntawm acidic thiab alkaline tshuaj lom neeg, ua kom lub sijhawm ntev - cov khoom siv ruaj khov.
Kev lag luam tsim hluav taws xob: Nws yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob thermal thiab lwm qhov chaw tsim hluav taws xob. Nws yog feem ntau siv los tsim cov khoom tseem ceeb xws li boilers thiab chav nruas. Cov khoom no yuav tsum tau ua haujlwm nyob rau hauv ntev - lub sij hawm siab - qhov kub thiab txias (txog 550 degree) thiab dais lub zog loj. Cov khoom siv tuaj yeem tswj xyuas lub zog zoo thiab ruaj khov ntawm qhov kub thiab txias, tiv thaiv cov cuab yeej deformation lossis kev puas tsuaj vim qhov kub thiab txias, uas yog qhov tseem ceeb rau kev nyab xeeb thiab siv hluav taws xob tsim hluav taws xob ntawm lub tshuab hluav taws xob.
General Heavy-Lub luag haujlwm Machinery & Cov Khoom Siv Tshwj Xeeb: Tshaj li cov kev lag luam loj saum toj no, nws kuj muaj cov ntawv thov hauv qee qhov hnyav - lub luag haujlwm tshuab ua haujlwm. Piv txwv li, nws tuaj yeem ua rau hnav- cov khoom tiv thaiv xws li cov thoob conveyor, crusher liner daim hlau, thiab cov ntaub ntawv khaws cia, cia siab rau nws cov tawv zoo thiab hnav tsis kam tiv thaiv kev sib txhuam thiab cuam tshuam thaum thauj khoom thiab crushing. Tsis tas li ntawd, nws tseem tuaj yeem siv tau rau hauv qee cov cuab yeej pabcuam ntawm cov chaw nres tsheb hydropower thiab txawm tias muaj feem cuam tshuam ntawm nuclear reactor siab hlab ntsha, ua tsaug rau nws cov khoom siv txhim khu kev qha thiab kev tiv thaiv corrosion.
