Taw Qhia Ntawm Phosphate Cib
Nyob rau hauv lub teb kiln, lub siab bauxite calcined ntawm txog 1600 degree yog tawg mus rau hauv siab bauxite aggregate ntawm 5-1 hli,<1.2mm, and the specific surface area of fine powder is ≥3500cm2/g. Its mineral composition is mainly α-A1203 and a small number of mullite (3Al2O3·2Si02).
Cov cementing tus neeg sawv cev yog tsim los ntawm kev lag luam phosphoric acid (H3PO4 concentration Ntau dua lossis sib npaug li 85%), muaj aluminium hydroxide thiab dej, qhov molar ratio: A12O3 / P2O5=1: 3.2, qhov sib ntxiv yog feem ntau yog hais txog { {9}}%, thiab qhov sib ntxiv ntawm li 2% ntawm cov av nplaum refractory los txhim kho kev ua haujlwm ntawm cov cib hnav-resistant. Txhim kho lub zog tho txawv ntawm phosphate cib. Nws tseem tuaj yeem txhim kho txoj haujlwm ntawm dai kiln ntawm daim tawv nqaij hauv refractory cib ntawm cement rotary kiln.
