Acid rain sampling, measuring and analyzing instrument

Abstract

The invention discloses an acid rain sampling, measuring and analyzing instrument which comprises metal shells. The metal shells are laminated and treated. A method for laminating and treating the metal shells includes steps of 1), sequentially inputting, by weight, 1-2 parts of dodecyl trimethyl ammonium bromide, 2.5 parts of aluminum oxide, 1.6 parts of dibutyl phthalate and 0.9 part of alum into 50 parts of deionized water and uniformly stirring the dodecyl trimethyl ammonium bromide, the aluminum oxide, the dibutyl phthalate, the alum and the deionized water to obtain first mixtures; 2), sequentially inputting, by weight, 15.5 parts of styrene, 9.9 parts of hydroxy propyl methylcelluloses, 1.8 parts of alkylphenol ethoxylate and 0.9 part of potassium tetraborate into the first mixtures, and continuing to stir the styrene, the hydroxy propyl methylcelluloses, the alkylphenol ethoxylate, the potassium tetraborate and the first mixtures until the styrene, the hydroxy propyl methylcelluloses, the alkylphenol ethoxylate, the potassium tetraborate and the first mixtures are sufficiently uniformly mixed with one another to obtain laminating and treating liquid; 3), placing the metal shells in the laminating and treating liquid, impregnating the metal shells in the laminating and treating liquid, taking the metal shells out of the laminating and treating liquid and then drying themetal shells. The acid rain sampling, measuring and analyzing instrument has the advantages that protective films cover the surfaces of the metal shells of the acid rain sampling, measuring and analyzing instrument, and accordingly the acid rain sampling, measuring and analyzing instrument is good in performance and high in surface smoothness.

Description

technical field [0001] The invention relates to an acid rain sampling and measuring analyzer. Background technique [0002] In the existing acid rain sampling and measuring analyzer, the oxidation resistance, abrasion resistance, corrosion resistance, rust resistance, heat resistance, cold resistance and weather resistance performance of the metal shell need to be improved, and the surface finish is not ideal. Contents of the invention [0003] The object of the present invention is to provide a kind of acid rain sampling and measuring analyzer, the surface of its metal shell is covered with a protective film, which has excellent oxidation resistance, abrasion resistance, corrosion resistance, rust resistance, heat resistance, cold resistance, weather resistance, and the surface High finish. [0004] In order to achieve the above object, the technical solution of the present invention is: a kind of acid rain sampling and measuring analyzer, which comprises a metal casing,...
