How do you know the color of silica gel products?
Many consumers are attracted by the color and appearance of some products, especially in gifts and crafts. As we all know,, Functional customized silica gel products are a kind of rubber and plastic products which are practical and beautiful inside and outside. They are also widely used in our life. In addition to the function, the reason why it can achieve multi-color effect and saturated color system is mainly that it also invests a lot of time in the aspect of appearance and color. What are the methods for deployment of detailed technology?
First of all, we need to know that the color pigment material of color masterbatch is silica gel material for coloring. Various color aids are added to silica gel material to achieve certain color system effect. Its compounding aids are mainly formulated for the raw materials of silica gel products, which can not be used in other materials, and the color deployment can be used in any products without any impact, such as life silica gel products, silica gel packaging Accessories, silicone gifts and some electronic accessories and so on.
What are the basic characteristics of silica gel color masterbatch?
1、 Light resistance of silica gel color masterbatch
The light resistance of silica gel color masterbatch refers to the light resistance of color masterbatch. Disperse the pigment in a certain medium, make a sample, and compare the degree of discoloration with the sample card of blue standard for fastness to sunlight under the specified light source after a certain time of exposure, and indicate that grade 1 is the worst and grade 8 is good.
2、 Heat resistance of silica gel color masterbatch
The heat resistance of silica gel color masterbatch refers to the heat resistance ability of color masterbatch. The larger the number, the better the heat resistance. The pigment is dispersed in polyolefin to make one third of the standard color, and stays for 5min after molding in injection molding machine.
3、 Migration resistance of silica gel color masterbatch
The migration resistance of silica gel color masterbatch refers to the migration resistance of color masterbatch. Migration refers to the migration of colorant from the inside of products to the surface of products or from a product to products and solvents through the interface.
In the process of production and processing of silica gel color masterbatch, under the effect of auxiliaries, silica gel color masterbatch is thoroughly connected with carrier through sufficient mixing. In the use, according to a certain share of the silica gel to be processed, the color masterbatch quickly enters the character and recognizes the "relative family" with the silica gel. Affinity compatibility is significantly better than toner coloring, so it is more appreciated by manufacturers of film and silica gel products.
