Hnub Kawg Ua Ntawv Thov: Lub Kaum Hli 8, 2022
Tam sim no, daim ntawv thov ntawm cov ntaub ntawv refractory nthuav qhia cov yam ntxwv ntawm paj, kev ua haujlwm, zoo, muaj ntau haiv neeg, kev ua haujlwm siab thiab kev siv tsawg, kev tsim cov khoom siv refractory yuav tsum hloov mus rau nws. Daim ntawv thov ntawm sodium 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. iav muajsodium hexametaphosphatemaj mam yaj hauv dej, yog li ntawd, siv los ua cov khoom siv refractory tom qab crushed rau hauv cov hmoov binder thaum xav tau kom ceev nws cov kev sib cais, nws tuaj yeem ua tau ib qho kev faib ua ke nrog dej, cia cov khoom siv refractory vim nws cov khoom siv hluav taws xob zoo thiab ua cov neeg to taub cov khoom siv. Raws li qhov tshwm sim, cov neeg siv khoom lag luam tseem yuav tsum paub txog cov txheej txheem cuam tshuam thaum xaiv cov khoom siv:
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 cov khoom siv magnesium ua cov khoom sib xyaw ua ke thiab hmoov, ntau dua 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. Lub ionized anion ntawm sodium hetaphosphate yaj nyob rau hauv dej adsorbed ntawm particle nto thiab ua rau cov electronegativity ntawm particle nto. Lub ionized Na + ions tuaj yeem ua kom cov tuab ntawm ob txheej hluav taws xob, thiabsodium hexametaphosphateplays ib tug dispersive nyhuv nyob rau hauv ob qhov teebmeem no.
Nyob rau theem no, cuam tshuam los ntawm kev lag luam poob qis, kev thov qis, cov peev txheej thiab ib puag ncig kev sib khi quab yuam nce, kev cuam tshuam ntawm cov yam ntxwv xws li kub kub kev lag luam thiab kev lag luam refractory tau nkag mus rau theem tshiab ntawm kev loj hlob ntawm kev hloov pauv huab hwm coj, kev hloov pauv ntawm cov ntaub ntawv refractory kuj yog. muab tso rau qhov kev thov tshiab, dhau qhov kev caisodium hexametaphosphateraws li binder tuaj yeem kho siv nyob rau hauv qhov kub thiab txias ib puag ncig, yog li txhim kho cov txiaj ntsig zoo.
