With the continuous development of book
printing technology, the application of environmental protection ink will
become the general trend. Now we will introduce the characteristics of
environmental protection soybean ink.
Environmentally friendly soybean oil ink
has the characteristics of non-toxic, tasteless, organic solvent-free
volatiles, low cost, wide source of materials, good gloss, precipitation
resistance, heat resistance, wear resistance, water washing resistance,
economic and health. According to the use of environmental protection soybean
ink, it can be divided into three types: high gloss, ordinary gloss and sub
gloss. From the screen technology can be divided into two categories: manual
screen printing and rotary screen printing. In the process of using water-based
high temperature resistant ink for silk screen printing, it can eliminate the
harm to human body and environmental pollution, and has been paid attention to
by packaging and book printing enterprises such as food, artificial leather,
bags and so on.
In addition to environmental protection,
environmental soybean ink has the following advantages compared with solvent
based screen printing ink:
1. Strong wear resistance. Packaging and
printing accessories need strong wear resistance, with 50 pressures per square
centimeter, it should reach 150 rubs per minute; the brightness is general, it
can reach 50-70 brightness units. Therefore, the packaging screen printing
products should not only be wear-resistant, resistant to 30 minutes' 8D_ It can
be washed with water, and it can meet the requirement when the temperature is
up to 121 � ~ 150 � (3 ~ 10 seconds).
2. Fast film forming and drying after
printing. The drying process of green soybean ink is 60% by evaporation or
volatilization, and 40% by material penetration and absorption. The drying
process is rapid, and the graphic conjunctiva of the printing ink can be
completed in a few minutes or dozens of minutes. If infrared or hot air drying
method is used, film-forming and drying can be promoted.
3. It is convenient and safe to use and
store, which is conducive to safe production and improving the working
conditions of operators. Because solvent based or oil-based screen printing ink
belongs to the category of dangerous goods, transportation, storage, use is
quite inconvenient. The environment-friendly high-temperature water-based
screen printing ink with water as solvent, no danger, safe and reliable use,
can use water to clean equipment and clean fingers.
After understanding the characteristics and
advantages of environmental protection soybean ink, it will help to carry out
environmental protection book printing work in the future.
