2. The preparation of the lining powder: The above-mentioned final immersion liquid 1000 ml in a 2000 ml beaker, heated to 98 ° C, and then added 4 g of ammonium persulfate with a magnetic stirrer stirring 0. 5h, after the oxidation of the solution, adding polyacrylamide 02%。 The solution, the volume of the solution is 0.02%. After lh filtration, the obtained filtrate is subjected to sulfurization and impurity removal, and zinc powder is substituted to obtain a zinc sulfate ammonia refining complex liquid. 122. 9g of antimony sulfide (without water) and 21. 7g of sodium sulfide (without water) are mixed and dissolved in distilled water to obtain a metathesis reaction solution, and a nonionic surfactant 0P-10 (for nonylphenol and epoxy) is added to the solution. The condensate of acetamidine) 0. 2g, the reaction temperature is 40 ° C, the stirring speed is 15m / s, stir well for 40min, then slowly added to 1000ml zinc sulfate ammonia refining complex, continue to stir for 30min and then add quality The fractionation is 30% 3⁄40 2 of desulfurization bleaching, and after bleaching, the nZnS-BaS0 4 crystal filter cake is separated by filtration.
