Abstract
The present invention provides a gold electroplating method for the surface of various flowers. When the method is adopted to electroplate gold on flowers, the flowers have the advantages of beautiful appearance, high intensity and natural texture. The method of the present invention can be also suitable for electroplating on leaves and the surface of beetles, the obtained products can obtain effects on emulating natural flowers, and the effects are difficultly obtained by other existing methods. The present invention can be used for manufacturing ornaments, such as ear rings, chest decoration flowers, necklace pendants, etc. In addition, when the gold electroplating method for the surface of various flowers offered by the present invention is adopted, the cost is low; the present invention is suitable for mass production.
Description
The present invention relates to a kind of technical field of electrogilding, specifically, relate to a kind of method of carrying out electrogilding on the flowers surface, also be applicable to simultaneously leaf or beetle are carried out electrogilding.
Electroplating technology is a kind of technology that is commonly used to the metallic conductor material surface is carried out functional or ornamental processing, material surface is carried out electrogilding can make material become attractive in appearance beautiful.Flower growth is in the Nature, because its bright-coloured beauty is often used as ornament, if can carry out electrogilding on the flowers surface, will obtain beautiful more permanent ornament, but because flowers are non-conductive, so can not carry out Direct Electroplating on its surface.The present domestic relevant technologies of not seeing as yet has in Italy and to utilize flowers to carry out covered with gold leaf the processing, can form one deck gold on the flowers surface like this, but this method cost is very high, and the gold on surface can't form and the former the same true texture in surface of spending.The U.S. has the people to use specific apparatus to carry out special " blowing flower " processing, can obtain like this and the gold of spending the same shape, but cost is very high like this, and its moulding also lacks natural aesthetic feeling.
Purpose of the present invention is exactly the electrogilding method that a kind of flowers will be provided, and also be applicable to leaf or beetle are carried out electrogilding, and cost is low, can realize scale operation.
The electrogilding method that realizes flowers of the present invention comprises following operation:
