Tam sim no, daim ntawv thov cov khoom siv refractory nthuav qhia cov yam ntxwv ntawm paj, muaj nuj nqi, sib txawv, kev txhim kho cov khoom siv refractory yuav tsum hloov kho nws. Daim ntawv thov ntawm sodium hexametaphosphateHauv cov ntaub ntawv refractory kuj ua tau raws li cov kev xav tau tshiab ntawm cov ntaub ntawv kev lag luam, thiab muaj cov yam ntxwv hloov tau ntawm cov khoom siv refractory yog qhov tseem ceeb ntawm kev sib txawv.
Tam sim no, qhov tshwm sim ntawm ntau cov ntaub ntawv tseem tuaj yeem ua tau raws li cov kev xav tau ntawm kev lag luam loj. Kev muaj tshebsodium hexametaphosphateMaj mam yaj hauv dej, yog li ntawd, siv ua cov khoom sib xyaw ua ntej, cia peb ua haujlwm ua ntu zus vim nws cov neeg muaj hluav taws kub ua tau zoo thiab dhau los ua neeg kom nkag siab cov khoom , vim yog qhov tshwm sim, cov neeg lag luam enprise tseem yuav tsum paub txog cov qauv cuam tshuam thaum xaiv cov khoom siv:
1. Kev ua haujlwm ntawm cov ntaub ntawv
2. Compressive lub zog ntawm cov khoom siv
Qee cov lag luam xaiv cov ntaub ntawv refractory, tsis yog xav txog kev ua kom tsis muaj zog, tab sis kuj ua kom lub zog ua kom tsis muaj zog, lub zog compressive ntawm cov ntaub ntawv.
Sodium hexametaphosphateYog cov khoom siv tshiab tshiab nrog cov khoom zoo hauv phosphate. Zoo thermal poob siab, siab compressive zog, slag corrosion tsis kam thiab cuam tshuam kev cuam tshuam, nrog siab softening kub nyob rau hauv load thiab tshuaj ruaj khov. Nws siv kub nyob ntawm ntau yam thiab qib ntawm raw cov ntaub ntawv, nruab nrab ntawm 1000 ~ 1800 ℃. Raws li qee cov khoom siv magnesium ua cov kev sib sau ua ke thiab cov hmoov, ntau yuav siv kev lag luam sodium hexametaphosphateraws li phau ntawv.
Tsis tas li ntawd, nws muaj ib txoj kab ntev ntev txuas, uas yog cov adsorped rau saum npoo ntawm cov pab pawg kawg, thaum lub sijhawm nruab nrab yog tsis koom nrog hluav taws xob rov qab. Cov ionized anion ntawm sodium hetaphosphate yaj nyob rau hauv cov dej adsorbed ntawm cov nplaim taws thiab nce lub electrongativity ntawm particle nto. Ionized na + ions tuaj yeem nce cov tuab ntawm ob lub fais txheej txheej, thiabsodium hexametaphosphateUa si lub dispersive nyhuv raws li cov teebmeem no.
Nyob rau theem no, cuam tshuam los ntawm kev lag luam downturn, tsis tshua muaj kev lag luam thiab kev txhim kho kub ntawm kev txhim kho ntawm cov khoom siv kub, kev yoog raws li cov khoom siv refractory kuj tseem muab rau pem hauv ntej qhov kev thov tshiab, dhau ntawm cov ib txwm muajsodium hexametaphosphateRaws li phau ntawv tuaj yeem siv tau kho nyob rau hauv ib puag ncig kub siab, yog li nce qib kev cuam tshuam.
