Several major environmental inks and their characteristics

Printing ink is composed of pigments, binders, fillers and other components to form a homogeneous slurry mixture. As a viscous fluid ink Dalian printing, due to the different properties of its varieties are also different, that is, there are thin points, differences in viscosity, fast dry and slow dry and so on. At present, several major environmental protection inks are required to meet the environmental protection requirements. First, the printing of ink components should be changed. That is, the use of environmentally friendly materials to formulate new inks. At present, environmental protection inks mainly include water-based inks, UV inks, water-based UV inks, and some alcohol-soluble inks.

The aqueous ink aqueous ink and the maximum difference between the solvent-based inks in a solvent thereof used is water and not an organic solvent, significantly reduce VOC emissions, can prevent air pollution printing UV, does not affect human health, nonflammable, ink stability, color Bright, non-corrosive plate business card printing press, simple operation, low price, good adhesion after printing, strong water resistance, rapid drying Xiamen printing factory, it is particularly suitable for food, beverages, pharmaceuticals and other packaging printed matter, is the world recognized environmental protection It is also the only ink approved by the U.S. Food and Drug Association in all printing inks. Therefore, water-based inks have excellent market prospects and relatively good profits. Due to the requirement of a large degree of difficulty, the relative quality of word printing will make the quality of the product superb. However, there are not many manufacturers of water-based ink, and there may be a great relationship with the use of raw materials. This remains to be done by our technical staff.

UV-curing ink three-dimensional printing UV-curing (UV) ink is the use of ultraviolet light of different wavelengths and energy to make the ink film and drying ink under ultraviolet irradiation. Utilizing different UV spectra, different energy can be generated to polymerize the monomers in different ink binders into a polymer printing plant in Xiamen, so the UV ink film has good mechanical and chemical properties. The main advantages of UV inks are: (1) no solvent; (2) fast drying and low energy consumption; (3) good gloss and vivid colors; (4) water resistance, solvent resistance, and good abrasion resistance. Other UV inks have a considerable market share. However, the market in 2006 is not optimistic, from the price changes in raw materials to product changes. The manufacturer's instability. Caused the UV ink in 2006 to stagnate. Really sorry. A friend who listened to selling UV monomers said that the unit sales for the year of 2006 were single. There is no more than half a year in 2005. Can imagine. UV inks are yet to be developed. The prospects are limitless. Photoinitiators in UV inks are a compound that is susceptible to photoexcitation and printing by Hefei. After absorbing light, they are excited into free radicals, energy is transferred to photosensitive molecules or photocrosslinkers, and UV inks undergo photocuring reactions. At present, UV ink has become a more mature ink technology, and its pollutant emissions are almost zero. In addition to the solvent-free, UV inks also have advantages such as a non-stick version of the disc printer, clear dots, bright and bright ink, excellent chemical resistance, and low usage.

Water-based UV inks Water-based UV inks are the new direction of UV ink research. Prepolymers in general UV inks are generally very viscous and need to be diluted with a reactive diluent. The currently used thinner acrylate compounds have different degrees of skin irritation and toxicity full-open printing, so while developing low-viscosity prepolymers and low-toxic reactive diluents, another development direction is to study water-based UV inks. That is, water and ethanol are used as diluents. At present, water-based UV inks have been successfully developed and have been used in some printing applications. In addition, alcohol-soluble inks that mainly play a role in flexo printing are also very small-printed ink printing photographs, and are mainly used in food, medicines, beverages, tobacco, and daily-use packaging and printing in contact with the human body. However, water-based UV requirements are relatively higher. Can make water-based UV inks. It will bring a qualitative leap to the industry and look forward to the arrival of this day.

High-Temperature Glass Inks However, the high-temperature glass ink I've made now differs from the aforementioned screen-printing inks, UV inks. Now called ink. We referred to him as low-temperature ink. The ability to withstand the temperature will not be higher than 100 degrees. However, due to the different requirements of the glass itself, there are strict controls on the temperature. Therefore, high-temperature inks are more suitable for screen printing and tempering of glass products.

However, the birth of this product. For the RMB printing industry in the glass industry, the ink industry is a good turning point. Reasons: After high temperature tempered glass products are not easy to crush, 100% higher than the hardness of flat glass, and after high temperature tempered glass ink it is not easy to fade, acid and alkali are A grade. Intangible, telling everyone that the printing factory, glass products have raised a new level. However, with the environmental protection certification put forward in 2006, we have our own new product of high-temperature environmental protection ink. Many friends in the glass understand it. Its application is also very extensive. In our daily lives, we often see encounters. For environmental protection. What our home appliances, all need environmental certification. However, due to lead-free and cadmium-free products, the brightness of the product will change. In this way, the quotation system is printed. Although our high-temperature glass is a very good current generation product, more problems and practical problems are waiting for our friends in the same industry to discuss common R&D.
