What are the main components of paper coating dispersants?
What are the main components of the paper ink powder? This is related to the things used in calligraphy and painting, and needs to be analyzed in detail.
In ancient techniques, paper ink powder often contains various materials. The first is plant fiber extract, and the cover paper is made of plant fiber, and the ink powder is also based on this. Or take mulberry skin, hemp strands, etc., and process them finely to make the fibers supple and adsorbent, so that the ink can be distributed smoothly between the papers without condensation.
Mineral powders are secondary. Such as kaolin, mica powder, etc., are mixed into it. The texture of kaolin is delicate, which can make the surface of the paper smooth and even, so that the ink can be spread evenly after falling off the paper; mica powder is shiny, and moderate addition can make the ink color show a unique charm between the paper, or increase its moisturizing, or add its transparency.
In addition, there are colloidal ingredients. Most of them are taken from the glue made of animal skin bones, such as kraft glue, staghorn glue and the like. The glue can bond with various materials to make them stick to each other, and act as a medium between the paper and ink, so that the ink is closely connected to the paper fibers, which not only ensures the durability of the ink color, but also controls the degree of dispersion, so that the ink does not spread indefinitely.
In addition, or with spices. The cover is used to remove odors, so that the paper ink powder has a fresh smell when used. Fragrance or choose natural flowers and plants, such as sandalwood, cloves, etc., when writing and painting, add elegance and make the mood more comfortable.
These various ingredients, after ingenious compatibility and proper blending, can form a paper ink powder, which in the way of calligraphy and painting, plays a natural and rich role in the color of ink, adding color to the creation of scholars and writers.

How do paper coating dispersants perform in different paper types?
Paper spraying agents have different properties in different types of paper.
Paper spraying agents are agents for adjusting the ink-spraying characteristics of paper. For paper with strong water absorption such as rice paper, paper spraying agents can regulate the penetration rate of ink. If the dosage is appropriate, it can make the ink rhyme naturally smudge, and the lines and ink colors transition softly. It can create a unique artistic effect when creating calligraphy and painting. However, if the dosage is inappropriate, or the ink color is too scattered, the picture is blurred and difficult to distinguish.
For paper with weak water absorption such as writing paper and printing paper, the effect of paper spraying agents is also different. It can reduce the surface tension of the ink, make the ink easier to adhere to the paper surface, avoid the ink penetration too fast, prevent the ink phenomenon on the back of the paper, make the writing clear, the printing pattern is accurate, the edges of the text and pattern are sharp, and there is no smudging and blurring.
Paper with different fiber components also has different reactions to paper powder. Paper with plant fibers is mainly due to its different fiber structure and porosity, and the diffusion and action mode of paper powder are also different. Wood fiber paper has a relatively tight structure, and the paper powder needs to be more finely prepared to achieve the ideal powder effect; while cotton fiber paper has a slightly looser texture, and the effect of paper powder is more obvious.
In different types of paper, due to the different characteristics of paper water absorption, fiber composition, etc., the ink may be moderately dispersed, smudged, or the handwriting pattern may be clear and sharp, and the performance is complex and diverse. It is necessary to adjust the dosage and formula of the paper powder according to the specific characteristics and usage requirements of the paper to achieve the best effect.

What are the specific effects of paper coating dispersants on the quality of paper coatings?
Paper dispersant has many effects on the quality of the paper coating layer. Paper dispersant can make the pigments, fillers and other particles in the paper coating layer evenly disperse without agglomeration. If the particles agglomerate, the surface of the paper is rough and the thickness of the coating layer is uneven, and the dispersant can avoid this drawback and make the coating layer smooth and even.
Furthermore, the dispersant can increase the stability of the paper coating layer. In the papermaking process, the stability of the pulp suspension is crucial. The dispersant can use its electric charge to make the particles have a repulsive force, making the suspension stable and not easy to settle. In this way, the quality of the coating layer of the paper can be guaranteed to be consistent everywhere, and there is no local threat of being too thick or too thin. The uniformity of the paper can be improved, the printability will also be improved, and the text and pattern printing will be clearer and more accurate.
And the dispersant also affects the strength of the paper coating layer. Good dispersion state can make the fiber and the pigment and filler bond more tightly. The fibers are intertwined with each other, and the pigment and filler are evenly distributed in it to form a stable structure. The tensile strength and burst resistance of the paper are enhanced.
In addition, the dispersant is related to the drying speed of the paper coating. Uniformly dispersed particles can make the evaporation path of water more regular. Moisture can escape in an orderly manner, preventing local moisture accumulation, speeding up the drying process, improving production efficiency, and avoiding problems such as paper deformation and wrinkling due to uneven drying.
Paper media dispersant has a far-reaching impact on the quality of paper coating, which is related to many aspects such as paper smoothness, uniformity, strength and drying performance. If it is used well, the quality of paper can be improved, which is of great contribution to the papermaking industry.

What is the optimum dosage of paper coating dispersant?
The question of the best dosage of paper spraying powder is related to the subtlety of skills and the suitability of materials. Looking at the description of "Tiangong Kaiwu", the dosage of various materials is based on experience and theory, in order to achieve the best effect.
Paper spraying powder, its use is aimed at controlling the ink characteristics of paper. If the dosage is too small, it will be difficult to avoid the effect of spraying, the ink will still seep wantonly, and the text and pictures will lose their clarity; if the dosage is too much, the paper may be stiff, the writing feel is not good, and the texture of the paper may be damaged, which will also increase the cost.
Ancient good workmanship, the amount of paper spraying powder varies according to the type, texture and use of the paper. If it is a paper for painting and calligraphy, the ink rhyme is vivid and does not spread too much, and the dosage is carefully controlled. It is usually measured in hundreds of catties of paper, and two or three taels are used for the loose agent. First, it is boiled with water, slowly added to the pulp, and stirred evenly, so that the agent and the pulp are seamlessly integrated.
This dosage is not static, and it also depends on the weather of the season. In the summer and wet season, the air is humid, and the paper is easy to spread ink. The dosage of the loose agent may be slightly increased; dry in autumn and winter, the dosage may be slightly reduced. Workers must judge the situation and fine-tune the dosage based on experience and spirituality to make the best paper.
If you want to do a good job, you must first sharpen your tools. The amount of paper powder is just like the yardstick in the hands of a craftsman. Only by accurately grasping it can you create paper that is suitable for books and paintings and of high quality. This is the wisdom of ancient papermaking and the essence of skills that should be inherited by future generations.

Ancient good workmanship, the amount of paper spraying powder varies according to the type, texture and use of the paper. If it is a paper for painting and calligraphy, the ink rhyme is vivid and does not spread too much, and the dosage is carefully controlled. It is usually measured in hundreds of catties of paper, and two or three taels are used for the loose agent. First, it is boiled with water, slowly added to the pulp, and stirred evenly, so that the agent and the pulp are seamlessly integrated.
This dosage is not static, and it also depends on the weather of the season. In the summer and wet season, the air is humid, and the paper is easy to spread ink. The dosage of the loose agent may be slightly increased; dry in autumn and winter, the dosage may be slightly reduced. Workers must judge the situation and fine-tune the dosage based on experience and spirituality to make the best paper.
If you want to do a good job, you must first sharpen your tools. The amount of paper powder is just like the yardstick in the hands of a craftsman. Only by accurately grasping it can you create paper that is suitable for books and paintings and of high quality. This is the wisdom of ancient papermaking and the essence of skills that should be inherited by future generations.
How is the compatibility of paper coating dispersants with other additives?
The compatibility of paper-based media dispersion with other additives is the most important factor in the work. The purpose of media dispersion is to make the media disperse evenly in the liquid medium to improve its performance. And other additives also have their own uses, such as retention assistance, enhancement, and waterproofing.
To investigate the compatibility of the two, the first is the compatibility. If the dispersed additives are similar, or the contained functionalities can interact with each other, the compatibility is good. For example, the dispersion containing carboxyl groups, the addition of amino groups can be increased by the addition of molecules or molecules to increase the harmony between the two and improve the compatibility.
Furthermore, the pH value of the two environments is considered. Different additives disperse at a specific pH value for the best performance. If the pH value of the two is similar, they can coexist and have their respective effects. For example, if a dispersion is suitable for an acidic environment, and a certain increase in performance is also excellent under acidic conditions, the compatibility between the two will be high under this environment.
In addition, the degree also has an impact. Some dispersions can only be maintained if they are added to a specific degree. If the two degrees of determination coincide, they can maintain good compatibility. For example, some polymers disperse some special additives, which have good compatibility under normal conditions, but the degree of resistance is high, and the disperse molecules can be added, or they can be added to separate the raw phase to break the compatibility.
In order to make the dispersion of the medium compatible with other additives, the comprehensive consideration of quantification, pH value, degree and other factors. Only by reasonably combining the two can they play the same role in engineering and other industries, and improve the quality of the product.
