Colloidal particle structure for enhancing precious metal covering efficiency

Abstract

The invention discloses a colloidal particle structure for enhancing precious metal covering efficiency. The colloidal particle structure comprises a colloidal particle main body, a water through hole, a first through hole and a second through hole, the colloidal particle main body is provided with the water through hole, the water through hole comprises the first through hole and the second through hole, the first through hole is arranged right above the second through hole, the first through hole is in communication with the interior of the second through hole, the first through hole is a straight through hole, the second through hole is a trumpet-shaped through hole, and the colloidal particle main body is made of a silica gel material. According to the colloidal particle structure, through the design that the second through hole is the trumpet-shaped through hole structure, when a precious metal solution enters the second through hole to be converged and then enters the first through hole, the water passing effect is greatly improved, through repeated tests, the production efficiency of the colloidal particle structure can be twice or above that of an original silica gel particle structure, and the colloidal particle structure is simple in structure, convenient to produce and process, low in cost and beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of noble metal coating, in particular to a colloidal particle structure that enhances the coating efficiency of noble metals. Background technique [0002] Nowadays, electronic products are becoming more and more popular in the market, and electronic products are becoming more and more refined, and the competition of products of various brands is fierce. Whether it is from the technical requirements of electronic products or the requirements of cost, the components of electronic products are becoming more and more refined. It is also for these reasons that the production requirements of the precious metal coating industry, which can be easily met, are now because the areas that need to be coated are as fine as 0.1, which leads to extremely low production efficiency, and even the precious metals cannot be coated because of the poor water flow effect. scrapped. [0003] The deficiencies of existing technolog...

Problems solved by technology

[0004] 1. In the existing technology, it is difficult to make a choice between the water passage efficiency and the size of the precious metal coating area. If the water passage hole is too small, it will lead to low production efficiency and even produce defective products. If the water passage hole is made too large, it will cause precious metal leakage. Going to the position that does not need to be coated leads to waste and even the size of the product plating area is out of tolerance

[0005] 2. The production speed and efficiency of the precious metal coating industry are not only related to the concentration and current of precious metals, but also directly related to the water holes in the coating area, and the size of the coating area is closely related to consumer electronics products. Under the commercial background of consumer electronics products becoming more and more refined, the water holes in the coating area can only be made smaller and smaller, which leads to lower and lower production speed and efficiency and increases the cost. Therefore, we propose an enhanced precious metal The colloidal structure of coverage efficiency further optimizes the existing technology
