What are the components of ink?

Inks are composed of pigments, connecting materials, fillers, additive materials, etc. The different properties of its varieties are also different, that is, there are differences in consistency and thinness, differences in viscosity, differences between fast drying and slow drying, and so on. It is of great significance to understand and understand the role of the components of the ink in the ink before printing, so as to accurately adjust the characteristics of the ink, meet the plasticity of various printing conditions, and improve the printing quality of the product.

The main components of ink are pigments and binders, and the auxiliary components include fillers, thinners, anti-crusting agents, anti-anti-anti-anti-anti-anti-slip agents and other additives.

The production process of electricity is extremely complex, with multiple processes such as power generation, transmission, distribution, and consumption. Among them, power generation refers to the place where electric energy is produced, such as: thermal power units, hydropower units, etc.; Transmission refers to the operation of using high-voltage lines to complete power transmission; Substation refers to the use of high-voltage substation to convert high-voltage voltage, ultra-high-voltage voltage and other electrical energy into low-voltage electrical energy; Distribution is the final step, which reduces the voltage and delivers the electricity to the consumer.

The power transmission and transformation project of the power system attaches importance to the two steps of transmission and transformation. With the rapid increase in China's electricity demand, there is an urgent need for power system transmission and transformation projects to undertake the transmission and transmission of the power system. A number of power transmission and transformation projects together constitute the main frame of China's power grid.

At this stage, China's power transmission and transformation projects generally have multiple voltage levels such as 110kv, 220kv, 330kv, 500kv, etc., of which 220kv is used more frequently in China; 330kV is commonly found in China's northwest power grid; The 500kV level is the highest, and the requirements for cost, capacity, and process are higher and more advanced. At present, China attaches great importance to the construction of 500kV power grid, which is the backbone of China's power grid. Power transmission and transformation engineering is an important engineering project in the construction of the main grid of the power grid, including transmission line engineering and substation engineering, which requires high costs, extremely complex engineering construction, and high construction technical requirements.

Power transmission and transformation projects generally include electrical installation, communication and automation, civil engineering, electrical equipment commissioning, system start-up and commissioning, etc. Among them, electrical installation includes the installation of primary equipment such as high-voltage equipment, and also includes the wiring and installation of secondary equipment such as protection and control systems; Communication and automation refers to communication engineering and substation automation; Civil engineering covers equipment foundation, building engineering, four-way and one-level, frame foundation, etc.; The commissioning of electrical equipment is to test and adjust the installed primary equipment and secondary equipment; System start-up and commissioning refers to the start-up and commissioning of the operation of transmission lines and substations after the construction of power transmission and transformation projects. The status quo of power system power transmission and transformation project management does not pay attention to the coordination of the project scheduleThe power system power transmission and transformation project is very different from other projects, and the requirements of the power system power transmission and transformation project are higher, and the construction progress is required to be carried out in strict accordance with the specified requirements to ensure that the project construction is completed on time.

At this stage, most of China's power enterprises do not pay attention to the management and coordination of the progress of power transmission and transformation projects, which seriously affects the quality of the project, which not only reduces the ability of construction personnel and engineers to control the progress of the project, but also has a great impact on the efficiency and quality of the project. A small number of power transmission and transformation projects only pay attention to the progress of the project, and lack the supervision of the project quality, resulting in the problem of urban power shortage.

Composition of ink:

1. Pigments, solid components in inks, color, black or white highly dispersed powder substances that are insoluble in water and organic solvents, are the chromogenic substances of inks, which can be divided into two categories: organic pigments and inorganic pigments. The saturation, tinting strength, transparency and other properties of the ink color are closely related to the performance of the pigment.

2. The binder material, the liquid composition of the ink, the binder can be made of various substances, such as dry vegetable oil, mineral oil, solvent and water and various synthetic resins. The fluidity, viscosity, neutral acid number, color intensity, water resistance, and performance of the printed matter during the use of the ink all depend on the binder.

3. Filler, white transparent, translucent or opaque powdery substance, plays the role of filling. The appropriate use of some fillers in pigments can not only reduce the amount of pigments to reduce costs, but also adjust the consistency and fluidity of inks, and also improve the flexibility of ink formula design.

Additive, in the manufacture or printing of ink, in order to improve the performance of the ink itself. When the ink composed according to the basic formula still cannot meet the requirements of use in some characteristics, or cannot meet the requirements of printing use due to the change of conditions, a small amount of additional material must be added to solve the problem.

The main components of inks are binders (resins), pigments, fillers, additives and solvents.

The ink consists of a primary and auxiliary component, which are homogeneously mixed and repeatedly rolled to form a viscous gelatinous fluid. It is composed of binders (resins), pigments, fillers, additives and solvents. It is used for books, packaging and decoration, architectural decoration and electronic circuit boards.

and other kinds of printing. With the increase of social demand, the variety and output of inks have also expanded and increased accordingly.

Features of the ink:

For ink, color, body bone (usually the rheological properties of ink such as consistency and fluidity are called the body bone of ink) and drying performance are the three most important properties of ink, and they should also be paid attention to when developing ink formulas and processes and producing inks; The film on the printed matter should have a certain resistance to make the printed product have practical use.

Mastering the deployment of spot color ink, the control of ink consumption, and the full use of residual ink can not only save materials, but also improve personal quality and technical level. An excellent ink blender plays a very important role in the development of new inks, color innovation, and the reduction of ink costs.

Pigments. Including pigments and dyes, pigments are divided into organic pigments and inorganic pigments, the former has bright tones, strong tinting strength, and is widely used in inks, such as azo and phthalocyanine pigments; The latter has good lightfastness, heat resistance, solvent resistance, and concealment, such as titanium dioxide, cadmium red, chromium green, ultramarine, etc. Pigments are tinted in a microgranular state, which is insoluble, and is the most commonly used pigment in inks.

Whereas, the dye is prepared into a solution when used, and it is colored in a molecular state, and the effect is not as good as that of pigments. The pigment can give the ink different colors and color concentrations, and make the ink have a certain viscosity and dryness.

Connecting materialIt is also one of the main components of ink, which plays the role of a medium for dispersion pigments and auxiliary materials, and is prepared by dissolving a small amount of natural resin, synthetic resin, cellulose, rubber derivatives, etc. in dry oil or solvent. There is a certain fluidity, so that the ink forms a uniform thin layer after printing, and forms a film layer with a certain strength after drying, and protects the pigment, making it difficult to fall off.

Therefore, choosing the right connecting material is one of the keys to ensure good printing, and the composition and ratio of the connecting material can be adjusted at any time according to the different packaging materials and printing requirements.

Ink is a homogeneous mixture composed of colored bodies (such as pigments, dyes, etc.), binders, fillers (fillers), additives and other substances; Able to print and dry on the printed body; It is a slurry adhesive with color and a certain degree of fluidity.

Therefore, color (hue), body bone (rheological properties such as thinness and fluidity) and drying properties are the three most important properties of inks.

Main ingredients: (1) pigments (including pigments and dyes): pigments can give different colors and color concentrations to the ink, and make the ink have a certain viscosity and dryness.

2) Connecting material: The ink forms a uniform thin layer after printing, and forms a film layer with a certain strength after drying, and protects the pigment and makes it difficult to fall off.

2) Thinner: reduce the viscosity of the ink, prevent the phenomenon of film peeling, and make the ink workable.

3) Anti-skin agent: inhibits the drying speed of the ink and prevents the ink from drying the conjunctiva mechanically.

4) Anti-anti-anti-printing agent: prevent the printing ink layer from being backprinted on the back of the paper to ensure the printing quality.

5) Slip agent: improve the friction resistance and fluidity of the ink, and reduce the viscosity.

6) Other additives: such as dispersants, wetters, desiccants, etc.

The main components of printing inks:

Main agent: pigments: organic pigments, lake pigments: inorganic pigments.

Connecting material: oil-type connecting material, resin type connecting material.

Organic solvents: additives, flow modifiers, viscosity modifiers, adhesion modifiers, anti-dirt agents, desiccation, conditioners, desiccation inhibitors, tone modifiers, dilution agents, color enhancement agents.

Pigment is a solid component in ink, which is the chromogenic substance of ink, and is not allowed to be water-neutral pigment. The saturation, tinting strength, transparency and other properties of the ink color are closely related to the performance of the pigment.

The binder is the liquid component of the ink, and the pigment is the carrier. In the printing process, the binder carries pigment particles, and the ink half of the printing machine is transferred to the substrate through the ink roller, the printing plate, and only permeates to form an ink film, which is fixed, dried, and adhered to the substrate. The gloss, dryness, mechanical strength and other properties of the ink film are related to the properties of the binder.

Additives added to the ink to improve the printability of the ink, such as: viscosity index, adhesion, dryness, etc.

The configuration process of ink is more complicated, the pigment, binder and additives are mixed into an oily paste in the ink mixer according to the proportion, and repeatedly rolled in the roller grinder to make the pigment evenly dispersed in the binder with fine particles.

1. The main components of ink are pigments, binders, fillers, thinners, dilutions, anti-crusting agents, anti-anti-anti-anti-anti-printing agents and slip agents, etc.

2. Ink is an important material used for printing, which is to express patterns and words on the substrate through printing or spray painting. The ink consists of the main and auxiliary components, which are evenly mixed and repeatedly rolled into a viscous gelatinous fluid.
