Cov pas nrig molybdenum huv si tau kho nrog alkali ntxuav, thiab saum npoo yog grey metallic luster thiab du. Alkali ntxuav txoj kev, tseem hu ua "alkali ua noj txoj kev", yog ib tug tshuaj ntxuav txoj kev.
Ntxiv lye rau hauv dej thiab tshem tawm cov av hauv qee qhov siab.
Cov tshuaj alkaline tuaj yeem ua rau cov av, thiab tom qab ntawd siv cov txheej txheem descaling. Tus nqi descaling feem ntau tuaj yeem ncav cuag 80%. Lye yog ib qho muaj zog lye, feem ntau yog ua los ntawm sodium hydroxide thiab sodium carbonate los yog trisodium phosphate.
Nws tuaj yeem soften, loosen, emulsify thiab disperse cov deposits ntawm molybdenum pas nrig, ua rau saum npoo ntawm molybdenum pas nrig tshwm xim hlau luster thiab ntau du. Thaum lub sij hawm alkaline tu, qee cov surfactants feem ntau tau ntxiv los ua kom cov nyhuv tu.
Qhov saum npoo ntawm molybdenum rods tau yooj yim oxidized, yog li deg oxides yuav tsum tau muab tshem tawm thaum siv. Thaum kho cov oxides saum npoo, cov kua qaub muaj zog (hydrofluoric acid, nitric acid, hydrochloric acid, thiab lwm yam) tuaj yeem siv.
Yog hais tias qhov saum npoo yog oxidized me ntsis, nws tuaj yeem ntxuav nrog xab npum abrasive, ces so nrog ib daim ntaub mos muag lossis daim txhuam cev, thiab thaum kawg ntxuav nrog dej sov.
Molybdenum rodsmuaj cov khoom kub kub zoo thiab feem ntau ua rau cov khoom kub kub siv rau hauv cov chaw kub kub sib txawv xws li aerospace thiab kev lag luam. Tsis tas li ntawd, nws kuj muaj cov thermal conductivity zoo, yog li nws feem ntau ua rau hauv cov khoom siv hluav taws xob siv rau hauv hluav taws xob.
