At present, there are many kinds of customized processing technologies for silica gel products. Different types of silica gel products need to be made by different processes, and most products cannot avoid the process of silk screen printing. For the silk screen printing process, it is not only used in the silica gel industry, but also used to print the logo of many products in daily life. Because the silk screen printing process has many advantages, it can be recognized in many industries, Its printing process is to use two-component liquid silica gel and curing agent color paste to prepare the required color for silk screen printing, and finally complete the silk screen printing process through the silk screen printing machine. In the silica gel products industry, its purpose is to achieve the printing of product appearance patterns with fonts. For example, our common silica gel gift logo is one of them.
The silk screen printing process has many excellent characteristics for other processes. First, it has good fluidity, strong paste viscosity and clear effect, stable high and low temperature printing resistance, good weather resistance and aging performance, etc. the product's silk screen printed patterns have a more three-dimensional and hand feel, and the silk screen printing plans also have excellent peel strength, wear resistance and brightness; It also has waterproof, anti-skid, breathable, high and low temperature resistance and outstanding leveling.
What details should silica gel manufacturers pay attention to in the production process of screen printing process? The effect of silk screen printing is closely related to the quality of the pattern, so it will appear in some processes such as silicone keys and silicone gift cups. The ink applied to the product is also very important to the silk screen printing process. The ink with good quality can improve the quality of the pattern, while some products will fade after long-term use. The following reasons lead to the fading of the product:
1. The quality of silk screen printing ink is poor, which affects the surface of silica gel products, resulting in poor silk screen printing effect;
2. The low baking temperature or short baking time after the silk screen printing of silica gel products leads to poor wear resistance of the silk screen printed silica gel product patterns, which begin to become blurred after several times of use;
3. The surface of the silica gel product is too dirty, and it is not cleaned before the silk screen printing, which hinders the adsorption between the silk screen printing ink and the silica gel, causing the characters to be wiped off with a little force.
