Abstract
The invention discloses a technology for prolonging the service life of etching liquor. The technology comprises the following steps: 1) adding 2%-15% of neutral salt into the etching liquor with low liquor activity, and meanwhile, adding 1.3%-4% of an oxethyl compound, wherein the reaction formula of SiF62-anion in the etching liquor and magnetic cation hydrolyzed in the neutral salt is as shown in the specification and the reaction formula of H<+> cation in the etching liquor and anion hydrolyzed in the neutral salt is as shown in the specification; 2) cavitating the uniformly stirred mixed solution in a magnetic field with strength of 20-40kHz, and then filtering out sediment (X2)(SiF6)n in the cavitated solution and making the solution with the sediment(X2)(SiF6)n filtered out pass through ion exchange resin, thereby acquiring filtrate; 3) adding deionized water into the filtrate acquired in the step 2) and keeping the pH value from 1.8 to 2.3. According to the technology, the service life of the etching liquor can be prolonged, the liquor activity can be guaranteed, the replacing period of the etching liquor can be prolonged and the isolating rate trend in the prolonging period of the service life thereof is stable.
