Alkliproof corrosion resistant ceramic packing and producing technique

[0022] According to the above-mentioned production process, using wollastonite, diopside, black talc, magnesite, and clay as the main raw materials, according to wollastonite 20%, diopside 10%, black talc 26%, magnesite 26%, 18% of clay, weighing 2000 kg, in accordance with the specified production process parameters, followed by ball milling, sieving, iron removal, filter press, staleness and vacuum mud smelting and other production processes to prepare plastic clay that can be used for molding. Material, choose φ25 rectangular saddle ring production mold, use suitable vacuum extrusion molding machine to produce φ25 rectangular saddle ring blank, after drying the blank, use 5m 3 Liquefied petroleum gas prismatic kiln firing, firing time is 10 hours, firing temperature is controlled at 1230 ℃, and then naturally cooled to below 200 ℃ out of the kiln. The sintered φ25 rectangular saddle ring has excellent alkali corrosion resistance. The product quality inspection results of the φ25 rectangular saddle ring are as follows:

[0023] Water absorption: 0.14%; Alkali resistance: 99.85%;

[0024] Bulk density: 2.68g/cm 3; Mohs hardness: 7;

[0025] Product performance meets the technical requirements of ceramic tower packing in the chemical industry.
