Tam sim no, daim ntawv thov cov khoom siv refractory ntawm cov yam ntxwv ntawm cov yam ntxwv, kev ua haujlwm, kho kom zoo, thiab kev txhim kho cov ntaub ntawv refractory yuav tsum hloov kho nws. Daim ntawv thov ntawmsodium 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. Ivey muaj sodium hetaphosphate yaj maj mam hauv cov hmoov, yog li ntawd cov khoom siv refractory rau nws cov kev paub hluav taws kub ua hauj lwm zoo thiab ua lub npe hu ua cov khoom siv. Yog li, cov neeg lag luam cov neeg lag luam tseem yuav tsum paub cov qauv uas muaj feem xyuam thaum xaiv cov khoom:
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. Nyob rau theem no, cuam tshuam los ntawm kev lag luam downturn, kev tiv thaiv tsis muaj zog siv cov peev txheej ntawm kev txhim kho ntawm huab cua loj, kev yoog raws li cov khoom siv refactory kuj tau muab tso rau pem hauv ntej qhov kev thov tshiab, dhau ntawm cov ib txwm muajsodium hexametaphosphateRaws li phau ntawv tuaj yeem siv tau hauv ib puag ncig ntawm qhov kub siab yog qeb duas ncaj ncees, cov nyhuv tiag tiag thiab kev nce qib.
