In a kind of better embodiment of the invention, a kind of enamel reaction still material being exclusively used in polyaluminium chloride production
Preparation method, specific steps are as follows:
(1) preparation of enamel powder: by 3g titanium carbide-acrylonitrile compound, 3g zirconium carbide-acrylonitrile compound, 4g oxygen
Change lanthanum-nitrile rubber composite material, 1g promethium oxide-nitrile rubber composite material, the cruel amine of 1g ethyoxyl laurel, 1g glycerol-tristearin
Acid esters, 1g tin-antiomony oxide, 10g aluminium nitride, 10g boron nitride, 3g sodium oxide molybdena, 3g lithia, 5g potassium oxide, 35g aluminum oxide,
30g silica, 20g diboron trioxide, 4g tin oxide, 3g calcium oxide, 5g zirconium dioxide, 3g barium monoxide, 2g titanium dioxide, 4g
Antimony oxide, 4g magnesia and 5g zinc oxide are put into mortar after mixing, are fitted into corundum crucible and are put into Muffle furnace and add
Heat keeps the temperature 0.5h, then transfers in high temperature box type resistance furnace to 650 DEG C, is warming up to 1300 DEG C from room temperature with furnace, heat preservation
Then 2h pours into the glaze of melting in cold water, make to melt glaze chilling and obtain enamel fragment, dry, then by porcelain
Glaze fragment is put into infrared baking oven and toasts 25h at 50 DEG C, crosses 800 meshes after the enamel fragment ball milling 25h of drying, obtains porcelain glaze powder
Material；
