core tip: UV ink and water-based ink will have a large market, and now most of the inks used in China are solvent based ink. Solvent based inks are volatile drying inks. The drying time is slow, and natural drying takes 8 hours. In the drying process, 60% of the solvent will volatilize. Under the current slogan of "returning to nature and environmental protection first", this serious pollution is not only restricted by the strict laws and regulations of government departments, but also opposed by the neighbors, and the printing factory does not want to use it. Therefore, it is inevitable that UV ink and water-based ink will occupy the printing market in the future

[Chinese packaging and those high-energy consumption products that cannot achieve green energy conservation news] UV ink and water-based ink will have a large market. Now most of the inks used in China are solvent based inks. Solvent based inks are volatile drying inks. The drying time is slow, and natural drying takes 8 hours. In the drying process, 60% of the solvent will volatilize. Under the current slogan of returning to nature and environmental protection first, this serious pollution is not only restricted by the strict laws and regulations of government departments, but also opposed by the neighbors, and the printing factory does not want to use it. Therefore, it is inevitable that UV ink and water-based ink will occupy the printing market in the future

I. market trend of silk printing ink (UV ink)

at present, volatile dry ink accounts for the mainstream in terms of output and varieties of silk printing ink. However, the output of UV ink increases year by year, with a large increase. It is only a matter of time before its output exceeds that of volatile dry silk printing ink. Due to the increase in the types of oligomers, prepolymers and polymerization initiators in the raw materials of UV silk printing inks, the application scope of UV silk printing inks is wider, which can be suitable for printing with various substrate materials, and its market share is bound to increase

1. Silk printing ink (UV ink) is suitable for all kinds of substrate materials. Paper, coated paper, wood products, synthetic paper, polyvinyl chloride (PVC (4565, 20.00, 0.44%)) 1 propylene (PMMA), acrylonitrile butene styrene terpolymer, acrylonitrile styrene copolymer, styrene (PS), ABS, polycarbonate (PC), polyester (PET), polyurethane, treated polyethylene, treated polypropylene, plastic (7885, 15.00, 0.19%) coating surface, polyethylene plastic (PE), wood products coating surface, coated metal plate Glass (869, -14.00, -1.59%), ceramic, thermosetting resin

2. Silk printing ink (UV ink) has strong functional performance. Silk printing ink (UV ink) is suitable for high-quality, diversified and special-shaped products that need special processing

① physical property: liquid crystal display screen, corrosion resistance cathode welding; Electrical includes insulation, conductivity, electric field luminescence, magnetism, etc; Foaming, thermography, pearlescent, fluorescent, nocrystal, heat transfer printing of thermal temperature, etc

② chemical and medicinal corrosion, ethanol stripping, etc; Biochemical ones include antibacterial and antifouling; Absorption, adsorption and reaction include water resistance, oxidation and corrosion, etc

③ surface decoration: crystal glue, anti metal etching, Matt wrinkles, non strong light, mirror metal, etc; Three dimensional, thick film printing, Braille, crystal patterns, wrinkles, broken graphics and texts, coral patterns, etc

The oil in the oil tank is sucked into the oil pump through the filter oil screen

II. Market trend of water-based printing ink

among volatile dry printing inks, water-based printing inks developed in the 1980s have been paid attention to because they are conducive to environmental protection. Water based printing ink was once noticed at the beginning of its development, but it was not popularized because of its poor water demand of the template and the wrinkle easily caused by the water absorption of the paper when printing on the paper. After entering the 1990s, the above problems have been gradually solved. With the advent of new water-based printing inks using urethane emulsions, their varieties are also increasing

objectively, because the function, use, price, equipment and supply of (water-based printing ink) are better than silk printing ink (UV ink), the traditional printing ink will slowly disappear in the silk printing ink market in the future, replaced by water-based ink and UV ink, and finally water-based ink will completely occupy the market. Commercialized water-based inks have been in line with the principles of simplicity, practicality and economy. The three major shortcomings that existed in the past have now been overcome

1. The drying problem of water-based printing ink

the biggest disadvantage of water-based printing ink is that its dryness is slower than that of solvent based printing ink. Theoretically, the evaporation energy of water is times greater than that of oil. How to improve the dryness is a comprehensive problem. After years of research, the composition of water-based printing ink has been completely improved. ① First, reduce the water content of water-based printing inks from 70% to 30%. ② It is to micronize the water-based printing ink, so that the water-based printing ink that can only be printed with 150 mesh silk can be printed with 300 mesh silk. In this way, the printing film is thinner and the drying is faster. ③ It is to reduce the viscosity of water-based printing ink, reduce the surface tension, and promote capillary phenomenon without hindering the printing effect, so as to improve the effect of evaporative drying and osmotic drying. ④ The most important thing is to have an efficient infrared dryer. Because infrared ray is radiation energy, it has penetrability, can directly interact with molecules in printing ink, heat inside and outside at the same time, and promote instant drying. Now water-based printing ink is used for color printing, and the instant drying between colors is only 5S at 150 ℃. This drying speed is almost as fast as silk printing ink (UV ink)

2. The following problem of water-based printing inks

in the past, water-based printing inks followed water absorbent objects (porous objects), such as cloth (cotton, hemp, wool, silk, polyester, nylon and their blends), paper (paper, paperboard), wood (wood, wood, plywood), leather (real leather, artificial leather) well, but it was difficult to follow hard surface printing materials. Now, because the fixing agent of water-based printing ink is acrylic, polyester, polyester coincidence resin, its omni-directional bonding function has excellent adhesion to non absorbent substrate, substrate with smooth and hard surface, and objects that used to be difficult to follow. Such as water repellent cloth, synthetic paper, thick canvas, rigid PVC, PVC, stickers, PVC cloth, artificial leather, acrylic, ABS, as, pet, PS, glass, hard aluminum foil, stainless steel, etc

3. Water based printing inks are all water-based.

although water-based printing inks in the past have been water-based, most of them add 10%-15% solvent in order to improve the softness, brightness and prevent infiltration of printing inks. Now the water-based printing ink can overcome the above problems, which is all water-based printing ink

the development of water-based printing ink has become a hot topic for silk printing industry. Because the state has regulations on environmental protection, printing practitioners have awakened themselves and have refused to use solvent based printing ink for their own health and switched to water-based printing ink. The neighbors of the printing factory will notify the environmental protection department as soon as there is a little peculiar smell; For orders received from export traders such as toys, clothing, furniture, curtains, etc., it is often noted that non-toxic printing ink should be used for processing; When purchasing T-shirts, consumers also learn to touch them with their hands to see whether they are printed with water-based printing ink. Customers should also ask whether they are printed with water-based printing ink when subscribing. Another reason is that all prepress can be processed by computer. From design, text, pattern, combination ② the industry concentration is increased to four-color film output, the urgent parts can be delivered in one hour, the plate making (four-color plate) is picked up on the same day, and the high-efficiency four-color printer and high-efficiency infrared instantaneous dryer are available, creating conditions for the use of water-based printing ink

today, with the rapid development of the Internet, many people are worried about the lack of quality assurance of the things they buy, but the printing cat based on the vertical e-commerce platform of the printing industry has no fakes at all. It is guaranteed that 100% of all efforts will be made to build two industrial clusters of polyurethane materials and high-performance high molecular materials. Customers who need UV ink, water-based printing ink and other printing inks, as long as they search on the printing cat, they will find the products you like
