Goldbronze Pigment
The goldbronze pigment (called gold powder) is used the kinghoren metal as its raw material, after special machine-finishing and surface chemistry processing system which results in having the flaky texture, can cohere foresees accurately in the float, presents the gold gloss, concludes to be one metal pigment with its pigment nature.As copper alloy with different ingredient and its surface may show the color of red, golden yellow, white even purple, its color effect will change to be different as per its different Znic content. Goldbronze pigment presents many kinds of different appearances, produces the light golden effect called Red Gold when its Znic content is lowder than 10%, produces rich pale golden effect called blue red gold when its Znic content is between 10%—25%, produces rich pale golden effect called blue red gold when its Znic content is between 25%—30%.
2.Microscopic appearance and grain-size distribution
The granule of gold bronze pigment is the flaky texture, obersving in scans under the electron microscope and discover that the most of its lamella is irregular, its edge assumes the denticle shape, few is a more regular circular.This kind of granule structure had decided its characteristic to be parallel ranking with the coating things.
3.Optics characteristic
The most importance characteristic of the goldbronze pigment as one of metallic pigment is its “different color effect along with the angle”, it refers that it can flash with the different brilliance, saturated, the appearance optical phenomenon by observing from different angle which causes by the incident light different scattering and the reflection way, this phenomenon is related to its smoothness of the metal surface. The material surface is smoother, brightness is higher. The factor which influences the glossiness of goldbronze pigment is various, such like its microscopic appearance, thickness and its direction ranking in the cementation which is very important. As a result of its magnificent metallic luster， which has contrasts the main body and the noticeable effect, widely applies in professions and so on in paint, printing ink, coating, plastic, silica gel, printing, dye printing, leather, toy, handicraft, Christmas present. The goldbronze powder and its finished product should store up in room temperature and under the dry environment; those goldbronze powder which has not used should be sealed immediately.
