Abstract

The invention discloses a titanium tube for a condenser, wherein a titanium tube main body is subjected to passivation treatment. The passivation treatment comprises the following steps: 1) adding sequentially 1-2 parts by weight of sulfamic acid, 2.6 parts by weight of hydroxyethylidene diphosphonic acid, 0.9 part by weight of 2-phosphate groups-1, 2, 4-tricarboxylic acid butane, 1.5 parts by weight of sodium tartrate and 1.77 parts by weight of cetylpyridinium chloride into 25 parts by weight of deionized water, and uniformly stirring the mixture; 2) then adding sequentially 0.5 part by weight of chromium chloride and 1.4 parts by weight of N-methyl-pyrrolidinone, 1.2 parts by weight of dioctylsulfosuccinate sodium salt, 0.7 part by weight of dinonylnaphthalenesulfonicacid sol and 0.7 part by weight of potassium tetraborate to continuously stir the mixture until the mixture is uniformly and fully mixed to prepare a passivation treatment solution; 3) putting the titanium tube main body into passivation treating liquid for the passivation treatment under the treatment temperature of 50 DEG C for the treatment time of 30 seconds, and washing and drying the titanium tube main body with pure water after the titanium tube main body is taken out. The titanium tube main body is subjected to the passivation treatment, so that performance is good and surface smoothness is nice.

Description
