Pigment and ink providers have been working to solve the issue of imperfect trestle life of ink. At present, gold and silver powder screen printing inks containing metal particles has been worked out The shortest form life is six months
The application of gold and silver powder in ink
Because the aluminum can behave with bedew or moisture and unshackle hydrogen, it may bob an explosion After the oxidation, the silver whitewash becomes gray and white. It is because the metal pigment is long-term mixed with a limpid link germane The chemical warmth and emulsification happens. After printing, these meagre sensitive areas make the color of printing materials or dilute ink color come out with the visual changes
The chemical characteristics of the gold and silver powder pigments they can not be directly added to the ink sold as a whole silicon powder product. Gold ink, silver ink used in metal powder is lightly oxidized copper and aluminum, the role of water, air, heat, certain chemicals will be absent metallic luster. They appear to be prosperous in gold ink, the pigment is made of copper, zinc, consisting of a compound in different proportions Layered gold and silver ink, the resin of the clarity of the higher musing of brighten is more, the improve the ink gloss
Pigment molecule size is too fine, commit relinquishment some of the luster, despite this predicament, and the greater the benefits are that the surface of the cage can be commensurate with sake sunshade (the twin burden of pigment fine particles than crude panoramic distribution area). The gem color is pearlescent pigment dispersion (or aluminum) in the unite to applicable or glassy light-colored ink made This silver can be used for layered paint ink, but a glaring color not as advantage as the range of the layered silver ink Also communication that the treated powder colouring to withstand the drastic premise as the treated silver paint.
In varied silver ink, if the aluminum pigment in powder form, obligatory to be extremely careful. Oxidation is one impetus why gold and silver powder ink color consistency strenuous to get Typically used in paint, the less the amend Therefore, use the least character of pigment underneath the premise can be matter to get the target color and canopy the cage province Able to withstand the loss and wear particles in the ink layer of metal above the ink film and then printed on varnished.
The metal powder is attainable to oxide, acceptance powder pigments for example, the oxidation occurs in the copper, zinc particles, resulting in the abridgement of the ink gloss, in some cases, the ink bequeath even present a irradiate green. Light syrup is starting to alter ink gloss, dibutyl is used to extend the fluidity of ink, the ink drying function, such as dibutyl and mexican oil, plus have an impact, add some wry oil, enabling speedy drying ink Silver ink blue background, for example, entrust exhibit a brighten unhappy Powder ink pre-printed has a yellow or uncooked ink film and the ink gold consign be changed.
In preceding developments, the metallic engender ink types include chrome-plated facade new effects Non-layered gold and silver ink has a extensive span in silver powder and nickel powder ink The challenge of creating such ink is: some red, orange and yellow pigments may act with metallic pigment thereby undermining the printed graphic Like any other products, screen printing partner understands gold and silver powder ink composition, producing process and functional limitations. The strengths of ink can be as much as practicable introduced to the customer So it is a glorious opportunity for ink printersSource:http://wwwmhcmpcom
