Sodium Fluorosilicate siv rau dab tsi?

Nyob rau hauv xyoo tas los no,sodium fluorosilicate iavtau tshwm sim los ua tus neeg tseem ceeb hauv ntau qhov kev lag luam, qhia txog nws txoj kev ua tau zoo thiab kev ua tau zoo hauv ntau daim ntawv thov.

Sodium fluorosilicate tshwm li dawb siv lead ua, crystalline hmoov, los yog tsis muaj xim hexagonal crystals.Nws yog odorless thiab tasteless.Nws tus txheeb ze ceev yog 2.68;nws muaj peev xwm nqus dej noo.Nws tuaj yeem yaj hauv cov kuab tshuaj xws li ethyl ether tab sis yog insoluble hauv cawv.Solubility nyob rau hauv acid yog zoo tshaj nyob rau hauv dej.Nws tuaj yeem decomposed hauv cov tshuaj alkaline, tsim sodium fluoride thiab silica.Tom qab searing (300 ℃), nws yog decomposed rau hauv sodium fluoride thiab silicon tetrafluoride.

Cov nroj tsuag kho dej thoob plaws ntiaj teb tau nce mus rau sodium fluorosilicate ua tus neeg sawv cev zoo rau fluoridation.Cov tshuaj no ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev noj qab haus huv ntawm cov hniav los ntawm kev tiv thaiv cov hniav lwj thaum ntxiv rau cov khoom siv dej pej xeem.Kev tshawb fawb dav tau txhawb nqa cov txiaj ntsig ntawm kev tswj cov tshuaj fluoridation, thiab sodium fluorosilicate tau dhau los ua qhov kev xaiv zoo tshaj plaws rau nws cov solubility thiab kev ua tau zoo hauv kev ua kom pom cov tshuaj fluoride.

Ntxiv rau nws lub luag haujlwm hauv kev noj qab haus huv ntawm qhov ncauj, sodium fluorosilicate pom daim ntawv thov hauv thaj chaw ntawm kev kho mob hlau.Kev lag luam uas vam khom rau cov hlau txheej, xws li tsheb thiab aerospace, leverage lub compound lub peev xwm los txhim kho corrosion kuj.Nws cov khoom tshwj xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv cov hlau los ntawm qhov hnyav ntawm ib puag ncig, ua kom lub neej ntev thiab ua haujlwm ntev ntawm cov khoom tseem ceeb.

Kev lag luam tshuaj lom neeg kuj tau txais sodium fluorosilicate rau nws lub luag haujlwm hauv iav ntau lawm.Ua raws li tus neeg sawv cev fluxing, nws ua kom yooj yim melting ntawm raw cov ntaub ntawv ntawm qhov kub thiab txias, txo kev siv hluav taws xob thiab cov nqi tsim khoom.Cov tuam txhab iav thoob ntiaj teb tau txais cov tshuaj sodium fluorosilicate los txhim kho kev ua haujlwm ntawm lawv cov txheej txheem thaum tswj xyuas qhov zoo thiab pom tseeb ntawm cov khoom kawg.
