Potassium Cryolite Npaj li cas?
Potassium cryolite npaj li cas? Niaj hnub no peb yuav kawm txog nws.
Potassium cryolite yog npaj los ntawm kev npaj cov txheej txheem sib xyaw sib xyaw thiab cov txheej txheem sib xyaw, thiab tseem tuaj yeem tsim ua cov khoom lag luam los ntawm kev tsim khoom ntawm qee yam khoom.
Txoj kev sib xyaw: Txoj kev yog sib tov thiab zom KF, AlF3, K3AlF4 thiab lwm yam khoom siv raw raws li kev faib ua feem ntawm cov khoom xyaw. Txawm li cas los xij, kev tshawb fawb sib xyaw thiab kev txhim kho ntawm kev npaj cov poov tshuaj crurite muaj qee qhov tsis zoo: tus nqi ntawm qee cov khoom siv raw yog siab thiab tsis yooj yim rau kev npaj, thiab cov khoom npaj tau qee zaum muaj dawb KF, uas yooj yim rau yaj hauv dej, nqus. dej, thiab tom qab ntawd ua rau corrosion ntawm weldparts.
Txawm hais tias cov kev tsis txaus no tuaj yeem zam tau yog tias siv txoj kev tshawb fawb yaj, kev ua haujlwm ntawm kev tshawb fawb yaj thiab kev txhim kho yog qhov nyuaj dua, kev siv hluav taws xob yog siab, thiab qhov kub siab melting thiab kev sib tsoo yuav tsum tau ua.
Synthesis method: Txoj kev zam qhov tsis txaus ntawm cov txheej txheem saum toj no, cov txheej txheem synthesis siv Al (OH) 3, HF, KCl, KOH, K2CO3, KBr thiab lwm yam khoom siv raw los tsim cov txheej txheem kev lag luam.
Qhov kom zoo dua ntawm cov txheej txheem synthesis yog tias nws tsis tas yuav tsum tau kub melting los yog sib tsoo, cov txheej txheem ntau lawm yog qhov yooj yim thiab yooj yim rau kev khiav lag luam, thiab cov khoom tsim cov poov tshuaj cryolite muaj cov khoom zoo, tsis tshua muaj nqi thiab tuaj yeem ua cov khoom loj. Nws yog dav siv hauv tsheb aluminium qhov chaw brazing kev lag luam.
Kev siv cov poov tshuaj cryolite
Potassium crolyte yog siv nyob rau hauv ntau industries, tab sis feem ntau lug siv yog txhuas thiab txhuas alloy brazing, poov tshuaj crolyte flux, yog ib qho tseem ceeb indispensable khoom rau kev sib txuas ntawm txhuas qhov chaw.
Raws li tus neeg sawv cev brazing, daim ntawv thov ntawm cov poov tshuaj crorite suav nrog: aluminium workpiece brazing sib koom tes tus neeg sawv cev, daim ntawv thov hauv Nocolok brazing txheej txheem, tooj liab alloy thiab stainless hlau brazing tus neeg saib xyuas, Nocolok brazing hlau thiab kev txhim kho.
Tsis tas li ntawd, potassium cryolite yog cov khoom siv tseem ceeb ntawm kev sib tsoo log. Piv nrog rau cryolite, poov tshuaj cryolite muaj qhov zoo tshaj plaws, xws li txo cov plua plav ntawm cov khoom sib tsoo log hauv kev sib tsoo thiab txiav, txhim kho tus nqi sib tsoo ntawm lub log sib tsoo, thiab txhim kho kev ua haujlwm ceev ntawm kev sib tsoo. Yog tias qhov tsis zoo yog tias tus nqi kim dua li cov pa cryolite.
Tsis tas li ntawd, potassium cryolite tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam steel smelting, iav thiab ceramics. Ntau cov lus nug txog potassium cryolite thov hu rau peb.
