2007 Chemical Industry Quotes - Ink Quotes

The ink was just beginning to touch in 2002. At that time I did some of the Merck's pearl powder... Pearl powder I think everybody knows. It's not introduced here. There are always square. There are many ink products. All of them need to be used. It has been very vague to think that paints and inks are different, but there are many similar operations and raw materials, but their use is very different.

Here I introduce to you a few commonly used inks:

Printing ink is composed of pigments, binders, fillers and other components to form a homogeneous slurry mixture. As a viscous fluid ink, 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.

The current major environmental protection ink

To meet the environmental protection requirements of inks, we must first change the ink composition, that is, use 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.

Water-based ink

The biggest difference between water-based inks and solvent-based inks is that the solvent used is water instead of organic solvents, which significantly reduces VOC emissions, prevents air pollution, does not affect human health, is not easy to burn, ink is stable, colorful, and does not corrode Plate material, simple operation, low price, good adhesion after printing, strong water resistance, rapid drying, it is particularly suitable for food, beverages, pharmaceuticals and other packaging printed matter, is the world recognized environmental protection printing materials, but also all current printing ink The only ink approved by the U.S. Food and Drug Association. Therefore, water-based ink has an excellent market prospects. The profit is also relatively good. Due to the greater difficulty required. Relatively speaking, the product quality will be excellent. But water-based ink manufacturers can not do much. May be with raw materials. There is still a great relationship with the application. This has yet to be continued by our technical staff.....

UV curable ink

UV-curable (UV) inks are inks that use ultraviolet light of different wavelengths and energies to form and dry inks under ultraviolet light. Utilizing different UV spectra, different energy can be generated, and monomers in different ink binders can be polymerized into polymers, 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 was not optimistic. From raw material price changes to product changes. Manufacturers' instability. Caused UV inks in 2006 to stagnate. Really regrettable. Listening to the sale of UV monomer friends said that the monomer sales for the year of 2006 haven't been as long as half a year in 2005. It can be imagined that UV inks are yet to be developed. The outlook is unsurpassed.

Photoinitiators in UV inks are compounds that are susceptible to photoexcitation. After absorption of light, they are excited into free radicals and the energy is transferred to photosensitive molecules or photocrosslinkers, causing UV inks to undergo photocuring reactions. At present, UV ink has become a more mature ink technology, and its pollutant emissions are almost zero. In addition to solvent-free, UV inks also have the advantages of not being easy to paste, clear dots, bright and bright ink, excellent chemical resistance, and low dosage.

Water-based UV ink

Water-based UV inks are currently 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. Therefore, while developing low-viscosity prepolymers and low-toxic reactive diluents, another development direction is to study water-based UV inks, that is, water. Ethanol and other diluents. At present, water-based UV inks have been successfully developed and have been used in some printing applications. In addition, alcohol-soluble inks, which mainly play a role in flexo printing, are also very small-pollution inks. They are mainly used in food, medicines, beverages, tobacco, and daily-use packaging and printing that are in contact with the human body. However, the water-based UV requirements are relatively higher. You can do water-based UV inks. It will bring a qualitative leap to the industry... Looking forward to this day...

High temperature glass ink:

However, the high-temperature glass ink I now make is different from the screen printing inks mentioned above. The UV inks are different. Now the so-called inks. We call them collectively low-temperature inks. The temperature resistance is not higher than 100 degrees. But Due to the different requirements of the glass itself, the temperature is also strictly controlled. Therefore, the high-temperature ink is more suitable for the first screen printing and then tempered glass process products.

However, the birth of this product is a good turning point for the glass industry and the ink industry. Reasons: 1. Glass products after high temperature tempering are not easy to crush, 1000% higher than the hardness of flat glass, and tempered glass Ink is not easy to fade, acid and alkali are all A grades. This is intangible, telling everyone that glass products have raised a new level. However, with the environmental protection certification put forward in 2006, we have our own new products. Ink. Glass is understood by many friends. Its application is also very extensive. We often see encounters in our daily lives. For the sake of environmental protection. What our household appliances, all need environmental certification. But due to lead-free Without cadmium, the gloss and vividness of the product will change. This way, although our high-temperature glass is a good modern generation product, more problems and practical problems are waiting for our friends in the same industry. Discuss common R&D together.

I hope these chemical products can accompany us to grow up, to mature together, and to succeed together.
