Dab tsi yog qhov txawv ntawm phosphorus impregnated av nplaum cib thiab tsawg porosity av nplaum cib?
1. Txheej txheem cej luam ntawm kev txiav-ntug
Phosphorus impregnated av nplaum cib thiab tsawg porosityav nplaum cibyog txawv, cov ntaub ntawv raw thiab impregnation txawv.
2. Kev piav qhia ntawm cov av nplaum tsis tshua muaj hluav taws kub cib
Qhov pores ntawm tsawg porosity refractory av nplaum hluav taws cib yog nyob nruab nrab ntawm 10-22%. Qhov tsis muaj porosity ntawm cov av nplaum uas tsis muaj porosity av nplaum yog tsuas yog ntxiv ib qho kev faib ua feem ntawm coke gemstones rau cov ntaub ntawv raw los kho qhov pores. Tom qab ntxiv coke gemstones, qhov ceev, lub zog, thiab corrosion kuj yog txhim kho los ntawm kev hloov ntawm coke pob zeb, thiab sintering kub ntawm low-pore av nplaum hluav taws cib yog siab, thiab cov khoom siv raw matrix hloov zoo heev. Kev tiv thaiv corrosion, thermal shock resistance, thiab lub zog yog zoo dua li cov av nplaum hluav taws zoo tib yam thiab phosphorus-impregnated cib. Tus nqi kuj txawv ntawm lwm cov cib fireclay.
3. Kev piav qhia ntawm phosphorus impregnated av nplaum cib
Phosphorus-impregnated av nplaum cib yog ua raws li cov av nplaum hluav taws zoo tib yam. Cov cib yog tsau nrog phosphoric acid nyob rau hauv ib lub thawv tshwj xeeb rau lub sijhawm, thiab tom qab ntawd raug rho tawm haujlwm zaum ob ntawm qhov kub ntawm qhov kub siab tshaj 200 degree, cia cov phosphoric acid nkag mus rau hauv av nplaum hluav taws los ntawm qhov qhib qhov hws. Nws nkag mus rau hauv lub puab ib feem ntawm lub cib thiab tso cai rau cov hlau thiab txhuas los teb, yog li txo qhov pores ntawm av nplaum cib thiab ua rau corrosion kuj ntawm cov av nplaum cib. Txawm li cas los xij, phosphorus-impregnated av nplaum cib yog teeb meem vim phosphorus-impregnated txheej txheem, thiab lub tsheb kiln tau yooj yim puas thaum lub sij hawm thib ob kub sintering txheej txheem. Yog li ntawd, cov chaw tsim khoom ntawm phosphorus-impregnated av nplaum refractory bricks yuav tsum muaj cov phosphorus-impregnated chaw tsim phosphorus-impregnated av nplaum firebricks. Txwv tsis pub, phosphorus leaching txheej txheem tsis tuaj yeem ua tiav.
04.Qhov txawv ntawm ob qhov lus dag hauv qhov pores
Qhov sib txawv ntawm phosphorus impregnated av nplaum cib thiab tsawg porosity av nplaum cib yog cov pores. Low-porosity av nplaum hluav taws cib tuaj yeem kho qhov pores raws li qhov siab ntawm qhov pores los ntawm kev ntxiv cov coke pob zeb hais, uas tuaj yeem ua qhov sib txawv ntawm qhov pores. Tom qab phosphorus-impregnated av nplaum hluav taws cib yog impregnated nrog phosphorus, lawv tsuas tuaj yeem txo qhov pores los ntawm 5% raws li qhov pores ntawm cov av nplaum zoo tib yam, thaum lub zog nce los ntawm 20%.
