Sodium Fluorosilicate siv rau dab tsi?

Nyob rau hauv xyoo tas los no,sodium fluorosilicatetau tshwm sim los ua tus neeg ua si tseem ceeb hauv ntau yam lag luam, qhia txog nws qhov kev ua tau zoo thiab kev ua tau zoo hauv ntau yam kev siv.

Sodium fluorosilicate zoo li siv lead ua dawb, hmoov crystalline, lossis cov siv lead ua hexagonal tsis muaj xim. Nws tsis muaj ntxhiab thiab tsis qab. Nws qhov ceev yog 2.68; nws muaj peev xwm nqus dej noo. Nws tuaj yeem yaj rau hauv cov kuab tshuaj xws li ethyl ether tab sis tsis yaj rau hauv cawv. Qhov solubility hauv acid zoo dua li hauv dej. Nws tuaj yeem lwj rau hauv cov kua alkaline, tsim sodium fluoride thiab silica. Tom qab hlawv (300 ℃), nws raug lwj rau hauv sodium fluoride thiab silicon tetrafluoride.

Cov chaw kho dej thoob plaws ntiaj teb tau siv sodium fluorosilicate ua ib yam khoom siv zoo rau kev ntxiv fluoride. 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 hauv cov dej pej xeem. Kev tshawb fawb dav dav tau txhawb nqa cov txiaj ntsig ntawm kev tswj hwm fluoridation, thiab sodium fluorosilicate tau dhau los ua qhov kev xaiv zoo tshaj plaws rau nws qhov kev yaj thiab kev ua haujlwm zoo hauv kev ua tiav cov qib fluoride zoo tshaj plaws.

Ntxiv rau nws lub luag haujlwm hauv kev noj qab haus huv ntawm qhov ncauj, sodium fluorosilicate pom kev siv hauv thaj chaw ntawm kev kho cov hlau saum npoo. Cov lag luam uas vam khom cov hlau txheej, xws li tsheb thiab aerospace, siv lub peev xwm ntawm cov tshuaj los txhim kho kev tiv thaiv corrosion. Nws cov khoom tshwj xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv cov hlau saum npoo ntawm cov teebmeem hnyav ntawm kev raug ib puag ncig, ua kom ntseeg tau tias lub neej ntev thiab kev ruaj khov ntawm cov khoom tseem ceeb.

Kev lag luam tshuaj lom neeg kuj tau txais sodium fluorosilicate rau nws lub luag haujlwm hauv kev tsim iav. Ua tus neeg sawv cev fluxing, nws pab txhawb kev yaj ntawm cov khoom siv raw ntawm qhov kub qis dua, txo kev siv hluav taws xob thiab cov nqi tsim khoom. Cov chaw tsim khoom iav thoob ntiaj teb tab tom txais sodium fluorosilicate los txhim kho kev ua haujlwm ntawm lawv cov txheej txheem thaum tswj hwm qhov zoo thiab meej ntawm cov khoom kawg.
