Tam sim no, daim ntawv thov ntawm cov ntaub ntawv refractory nthuav qhia cov yam ntxwv ntawm cov yam ntxwv, functionalization, diversification, refinement, high efficiency thiab tsawg noj, thiab kev loj hlob ntawm refractory ntaub ntawv yuav tsum tau hloov mus rau nws. Daim ntawv thov ntawmsodium hexametaphosphatenyob rau hauv cov ntaub ntawv refractory kuj ua tau raws li cov kev xav tau tshiab ntawm cov neeg siv kev lag luam, thiab kev txhim kho cov kev taw qhia ntawm cov khoom siv refractory, xws li cov yam ntxwv, kev sib koom ua ke, ntsuab, tsis siv neeg, yog li kev hloov pauv ntawm cov khoom siv refractory yog qhov tseem ceeb ntawm kev sib txawv.
Tam sim no, qhov tshwm sim ntawm ntau yam ntaub ntawv tseem tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam loj. Cov iav muaj sodium hetaphosphate yaj maj mam yaj hauv dej, yog li siv los ua cov khoom siv refractory yog yuav tsum tau pulverized rau hauv cov hmoov kom nrawm nws cov kev tawg, nws tuaj yeem tov nrog dej hauv txhua qhov kev faib ua feem, kom cov ntaub ntawv refractory rau nws cov hluav taws kub zoo thiab ua lub npe hu ua khoom. Yog li ntawd, cov neeg siv khoom lag luam tseem yuav tsum paub txog cov qauv tsim nyog thaum xaiv cov ntaub ntawv:
1. Refractoriness ntawm cov ntaub ntawv
2. Compressive lub zog ntawm cov khoom
Qee lub tuam txhab xaiv cov ntaub ntawv refractory, tsis tsuas yog xav txog cov refractoriness, tab sis kuj yog cov refractoriness thiab kub tsis kam, compressive zog ntawm cov ntaub ntawv.
Sodium hexametaphosphateyog cov khoom siv refractory tshiab nrog cov khoom zoo hauv phosphate. Zoo thermal shock stability, siab compressive zog, slag corrosion kuj thiab cuam tshuam tsis kam, nrog siab softening kub nyob rau hauv load thiab tshuaj stability. Nws siv kub nyob ntawm ntau yam thiab qib ntawm cov ntaub ntawv raw, ntawm 1000 ~ 1800 ℃. Raws li qee qhov siv cov khoom siv magnesium li refractory aggregate thiab hmoov, ntau yuav siv kev lag luam sodium hexametaphosphateua binder.
Tsis tas li ntawd, nws muaj ib tug linear ntev saw configuration, uas yog adsorped rau saum npoo ntawm cov particle los ntawm cov pab pawg neeg kawg, thaum lub nruab nrab saw yog yeej tsis muaj kev koom tes nyob rau hauv kev sib raug zoo, uas yuav muab ntxiv electrostatic repulsion. Nyob rau theem no, cuam tshuam los ntawm kev lag luam poob qis, kev xav tau tsis muaj zog, kev sib khi quab yuam nce, kev cuam tshuam ntawm cov khoom siv thiab kev tiv thaiv ib puag ncig kub kub kev lag luam thiab kev lag luam refractory tau nkag mus rau theem tshiab ntawm kev txhim kho ntawm kev hloov pauv huab hwm coj, kev hloov pauv rau cov khoom siv raw khoom. kuj tau muab tso rau qhov kev thov tshiab, dhau ntawm cov tsoossodium hexametaphosphateraws li binder tuaj yeem siv rau hauv ib puag ncig ntawm qhov kub thiab txias yog ranked txoj cai, cov nyhuv tiag tiag thiab kev vam meej.
