What are the advantages of environmentally friendly soybean ink?
With the continuous development of technology in the printing industry, the application of environmentally friendly inks will become the general trend. Here we will introduce the characteristics of environmentally friendly soybean ink. Environmentally friendly soybean ink has the characteristics of non-toxic, odorless, organic solvent-free volatiles, low cost, wide source of materials, good gloss, resistance to precipitation, heat resistance, abrasion resistance and water washing resistance, economic health. Environmentally friendly soybean inks can be divided into three types: high gloss, ordinary gloss, matt, etc. according to product use. It can be divided into two types from the screen technology: manual screen printing and rotary screen printing. During the use of water-based screen printing high temperature resistant ink, it can eliminate the harm to the human body and the pollution to the environment. It has begun to be valued by packaging and printing companies such as food, artificial leather, and luggage. In addition to environmental protection, environmentally friendly soy inks have the following advantages over solvent-based screen printing inks: 1. Strong wear resistance. Packaging and printing jewelry needs a strong abrasion resistance, measured at 50 pressures per square centimeter, and generally should reach 150 rubs per minute; the general gloss is 50 to 70 brightness units. Therefore, the packaged silk-screened product must not only be wear-resistant and resistant to 30 minutes`8d_? Clock wash, but also meet this requirement when it reaches 121 ° C to 150 ° C (3 seconds to 10 seconds). 2. The film formation speed after printing is fast and drying is fast. The drying process of environmentally friendly soybean ink is 60% by evaporation or volatilization, and 40% is absorbed by the material. It dries quickly, and can complete the graphic conjunction of the printing ink in about a few minutes or tens of minutes. If using infrared or hot air drying method, it can promote the film drying. 3. It is convenient and safe to use and store, which is conducive to safe production and improve the working conditions of the operating staff. Since solvent-based or oil-based screen printing inks belong to the category of dangerous goods, transportation, storage and use are quite inconvenient. The environmentally friendly high-temperature water-based screen printing ink uses water as a solvent without any danger. It is safe and reliable to use and can be used to clean equipment and fingers. After understanding the characteristics and advantages of environmentally friendly soybean ink, it will help the future development of environmentally friendly printing.
