How to say water-based ink in English?

Ink (printing ink) is an important material for printing, and patterns and characters are displayed on the substrate by printing or inkjet printing. Ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled to form viscous colloidal fluid. It consists of adhesive (resin), pigment, filler, additive and solvent. Used in books and periodicals, packaging and decoration, architectural decoration and electronic circuit board printing. With the increase of social demand, the variety and output of ink also expand and increase accordingly.

pigment

Include pigments and dyes, and pigments can be divided into organic pigments and inorganic pigments. The former has bright colors, strong coloring power and short drying time, so it is widely used in inks, such as azo pigments and phthalocyanine pigments. The latter has good light resistance, heat resistance, solvent resistance and concealment, such as titanium dioxide, cadmium red, chrome green, ultramarine and so on. Pigment is colored in granular state and insoluble in water. It is the most commonly used pigment in ink. However, when dyes are used, the effect is not as good as that of pigments when they are prepared into solutions and colored in molecular state. Pigments can give ink different colors and color concentrations, so that ink has a certain viscosity and dryness.

Ink binder

As one of the main components of ink, it plays a medium role in dispersing pigments and auxiliary materials. It is made by dissolving a small amount of natural resin, synthetic resin, cellulose and rubber derivatives in drying oil or solvent. It has certain fluidity, which makes the ink form a uniform thin layer after printing, and forms a film layer with certain strength after drying, which protects the pigment and makes it difficult to fall off.

Adhesives have a great influence on the printability and printing effect of ink, such as transferability, brightness, fixing speed and so on. Therefore, choosing suitable adhesive is one of the keys to ensure good printing. It is necessary to adjust the composition and proportion of adhesive at any time according to different packaging materials and printing requirements.

filler

It is an auxiliary agent for adjusting ink concentration, and can also increase the thickness of ink film and improve wear resistance. It has no coloring power and hiding power. Mainly barium sulfate, talcum powder, calcium carbonate, aluminum hydroxide and so on. When used, it is ground into white powder.

Ink thinner

Its function is to reduce the viscosity of ink, prevent filming and make ink suitable for operation. Commonly used diluents are oligomeric linseed oil, mineral oil, etc. The former is easy to mix with ink and has a soft effect; The latter has obvious dilution effect, but it should not be excessive, otherwise the printing effect is not good.

Anti-skinning agent for ink

Its function is to inhibit the drying speed of ink and prevent ink from mechanically drying conjunctiva. Its main components are organic reducing agent and antioxidant. It can be added to ink, or it can be spread on machines that come into contact with ink.

Ink anti-reverse printing agent

Its function is to prevent the ink layer from being printed on the back of the paper, thus ensuring the printing quality. The most commonly used anti-reverse printing agent is corn starch.

Ink slip agent

Its function is to improve the friction resistance and fluidity of ink, reduce viscosity, improve the smoothness of film, and reduce the phenomenon of paper napping. The commonly used slip agents in ink are high melting point microcrystalline wax and synthetic wax.

Other additives for ink

There are many other additives, such as dispersants, wetting agents, desiccants, stabilizers and so on.

The vowel letter I is pronounced with short vowels in stressed closed syllables. When pronouncing, the end of the tongue is close to the lower teeth, the front of the tongue is raised, the tongue is in a middle and high position, it does not touch the upper jaw, there is no friction, the gums are half closed, and the lips are flat, which appears at the beginning, middle and end of the word. For example:

Lick

66

apron

Pig

Pin pin

Kiss

Ink ink

Hill, hill
