Sodium Tripolyphosphate: Ib qho khoom siv ua kom muaj zog ntau yam hauv kev lag luam
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam tshuaj ntxuav khaub ncaws, sodium tripolyphosphate yog ib qho tshuaj ua kom cov tshuaj ntxuav khaub ncaws zoo. Nws tuaj yeem chelate calcium thiab magnesium ions hauv dej, ua kom cov dej mos thiab txhim kho lub zog ntxuav ntawm cov tshuaj ntxuav khaub ncaws. Tsis tas li ntawd, sodium tripolyphosphate tuaj yeem tiv thaiv kev rov ua dua ntawm cov av, ua rau cov khaub ncaws thiab cov tais diav huv dua. Nws yog siv dav hauv cov hmoov ntxhua khaub ncaws, cov tshuaj ntxuav tais diav, thiab cov tshuaj ntxuav hauv kev lag luam.
Hauv kev kho dej, sodium tripolyphosphate yog siv los ua cov dej mos thiab cov tshuaj tiv thaiv xeb. Nws tuaj yeem tsim cov dej tsis yaj nrog calcium thiab magnesium ions hauv dej, txo cov dej tawv thiab tiv thaiv kev tsim cov nplai. Tib lub sijhawm, sodium tripolyphosphate tuaj yeem tsim cov zaj duab xis tiv thaiv ntawm cov hlau kom tiv thaiv kev xeb, ua kom lub neej ua haujlwm ntawm cov khoom siv ntev dua. Nws yog siv dav hauv cov tshuab dej txias hauv kev lag luam, kev kho dej boiler, thiab kev kho dej haus.
Hauv kev lag luam ua zaub mov, sodium tripolyphosphate yog siv los ua cov khoom noj ntxiv. Nws tuaj yeem ua haujlwm ua tus txhim kho zoo rau kev khaws cia thiab ua kom nqaij, ntses, thiab ntses hiav txwv mos. Sodium tripolyphosphate tuaj yeem chelate cov hlau ions hauv zaub mov, tiv thaiv kev oxidation thiab kev lwj, thiab ntev lub txee lub neej ntawm cov zaub mov. Tsis tas li ntawd, nws tuaj yeem siv los kho pH ntawm zaub mov, txhim kho nws cov saj thiab cov qauv.
Hauv kev lag luam ceramics thiab iav, sodium tripolyphosphate yog siv los ua flux. Nws tuaj yeem txo qhov kub sintering ntawm ceramics thiab iav, txhim kho cov khoom zoo thiab cov txiaj ntsig. Sodium tripolyphosphate kuj tseem tuaj yeem txhim kho qhov ci thiab pob tshab ntawm ceramics thiab iav, ua rau lawv zoo nkauj dua thiab ua tau zoo dua.
Txawm hais tias nws muaj ntau yam kev siv, sodium tripolyphosphate muaj cov dej solubility siab, thiab nws siv yuav tsum tau tswj hwm cov tshuaj kom nruj kom tsis txhob muaj kev cuam tshuam rau ib puag ncig. Hauv kev siv hauv kev lag luam, kev siv sodium tripolyphosphate feem ntau tshwm sim hauv cov kab ke kaw kom txo qis kev cuam tshuam rau ib puag ncig. Tsis tas li ntawd, cov txheej txheem tsim khoom ntawm sodium tripolyphosphate tseem niaj hnub raug kho kom zoo dua los txhim kho kev siv cov peev txheej thiab txo cov dej khib nyiab tawm.
