Cov Khoom Thiab Daim Ntawv Thov Ntawm Super Qib Phosphate High Alumina Brick

Phosphate siab alumina cib yog tsim los ntawm cov neeg kho tshuab nias nrog phosphoric acid tov los yog txhuas phosphate tov (aluminium dihydrogen phosphate tov, PA-80 kua nplaum) li binder thiab bauxite clinker li aggregate thiab kho cua sov ntawm 500 degree. Cov tsoos phosphate siab alumina cib muaj ob qho kev tsis txaus ntseeg: ib qho yog qhov qis qis qis, txog 1300 degree; lwm qhov yog qhov loj reheating shrinkage, uas cuam tshuam rau daim ntawv thov cov nyhuv thiab thaj chaw ntawm cov khoom. Super qib phosphate siab alumina cib zoo txhim kho ob lub ntsiab lus. Los ntawm kev ntxiv cov hmoov zoo ntawm cov khoom siv refractory nrog micro nthuav dav ntawm qhov kub thiab txias ua haujlwm zoo, nws txhim kho cov khoom muag muag kub ntawm cov khoom, txo qhov kub thiab txias shrinkage, thiab txhim kho lub zog, thermal poob siab thiab hnav tsis kam. Lub load softening kub ntawm cov khoom mus txog ntau tshaj 1500 degree, uas tau zoo siv nyob rau hauv lub hnav-resistant ib feem ntawm lub kiln.
