Embodiment Construction

[0021] Such as figure 1 As shown, this embodiment discloses a surface treatment method for sanitary products. This method is used for surface nickel and chrome plating of bathroom products. The method includes the following steps:

[0022] (1) First put the sanitary products in dewaxing water with a concentration of 2-4%, keep the temperature at 65-75°C for 6-10 minutes; then add an ultrasonic device to perform ultrasonic de-waxing in the temperature range of 60-65°C Wax for 2 to 3 minutes, and then enter the next step after washing with water.

[0023] (2) Perform multiple ultrasonic degreasing and chemical degreasing, including the first, second, third ultrasonic degreasing and one chemical degreasing steps. The first ultrasonic degreasing step: carried out in a solution with a concentration of 40-50g / L added with degreasing powder, at a temperature of 60-65°C, and for 2-3 minutes; chemical degreasing step: after adding degreasing powder The concentration of the powder i...

Abstract

The invention aims to provide a sanitary product surface treatment method which can be adopted to strengthen density of a coating on the surface of a sanitary product, raise quality of the coating of the product and prolong service life of the product. The method provided by the invention comprises the following steps: wax removal step, oil removing step, electrode electrolysis step, activating treatment step, nickel plating processing step and chrome plating step. By the adoption of the method for processing a sanitary product, density of the surface of the sanitary product is higher, the thicknesses of a nickel coating and a chromium coating are increased, and quality of the coating of the sanitary product is improved. Thus, the service life of the sanitary product in a general environment is prolonged, the sanitary product can be suitable for more other complex environments, and the service life can be guaranteed. The Sanitary product surface treatment method provided by the invention can be applied in the field of production of sanitary equipment.

Description

technical field [0001] The invention relates to a method for treating the surface of sanitary products, in particular to a method for performing nickel plating and chrome plating on the surface of sanitary products. Background technique [0002] With the rapid development of the sanitary industry and the continuous improvement of people's living standards, people have higher and higher requirements for sanitary products such as faucets. For bathroom products, people not only pursue high-end appearance, but also pursue products with a long service life and guaranteed quality. As daily necessities, bathroom products must be able to adapt to various complex environments. The quality of bathroom products is determined during the manufacturing process. In order to ensure the quality of sanitary products, it is necessary to carry out environmental simulation tests on the products during the manufacturing process. The sanitary industry usually uses NSS (Neutral Salt Spray Test) ...
