What are the main components of Retention Aid?
Retention Aid, an auxiliary used in papermaking, aims to improve the retention rate of fibers and enhance the quality of paper. Its main components are complex and have various characteristics and effects.
The first is natural polymer, such as starch. Starch is a common energy storage polysaccharide in plants. It is specially modified during papermaking to enhance the bonding force between fibers. Its molecules contain many hydroxyl groups, which can be connected to the hydroxyl groups on the surface of the fiber by hydrogen bonds, so that the fiber interweaves more tightly and improves the retention rate. And can improve the physical properties of paper, such as enhancing the strength of paper.
In addition, synthetic polymer, polyacrylamide is common among them. According to the ionic characteristics, it can be divided into cationic, anionic and non-ionic. Cationic polyacrylamide can attract negatively charged fibers by electrostatic attractive force, forming an adsorption layer on the fiber surface, promoting fiber flocculation and improving retention. The anionic type is often matched with cationic additives to optimize fiber retention through charge neutralization and bridging.
In addition, inorganic particles are also important components of Retention Aid, such as bentonite. Bentonite is a clay mineral with good adsorption and expansion. In the papermaking system, it can be adsorbed on the surface of fibers and polymers to build a denser network structure, improve the connection between fibers, improve the retention effect, and improve the uniformity of paper.
There are also indispensable retention aids in the retention aid system, such as the combination of cationic starch and bentonite. The synergistic effect of the two, cationic starch is first adsorbed on the fiber, and bentonite is then adsorbed on it to strengthen the connection between the fibers, accelerate the dehydration process, improve the retention rate and water filtration performance, which is of great significance to the efficient production of papermaking. The components of Retention Aid cooperate with each other to improve the quality of paper and optimize the papermaking process, playing a crucial role.

How to Use Retention Aid Properly
Retention Aids, retention aids are also used in the papermaking process to improve the retention rate of fibers and fillers. If you want to use it properly, you should follow the ancient principles as recorded in "Tiangong Kaiwu".
Although "Tiangong Kaiwu" does not directly describe retention aids, its method of papermaking can be used for reference. At the beginning of papermaking, the preparation of materials needs to be fine. Cut bamboo and hemp, you must choose good materials, wash and pound, so that the fibers are uniform and fine. This is like the application of retention aids, when the material characteristics, fiber length, thickness, type of filler, and particle size are known in advance, they are all related to the effectiveness of retention aids.
After soaking and drying, when copying paper, there should be a way to apply retention aids. The dosage cannot be exceeded or lacking. Excessive amounts of paper will cause many diseases, such as reduced strength and difficult water filtration; lack of paper will cause poor retention, damage to materials and sewage. When seeking the appropriate amount with a small trial, it is like a light boat testing the water at the beginning, and slowly explore it.
In addition, the method of applying medicine is also important. Or enter when beating, or add it before the Internet, depending on the state of the fibers and fillers. If you enter when beating, you can get in touch with the fibers as early as possible. If you add it before the Internet, you can respond quickly and help keep it in time. This is like marching and setting up an array, and the timing and location are all important.
In addition, environmental factors should not be ignored. Water temperature and pH value all affect the activity of retention aids. The water temperature should be suitable, the cold agent is difficult to dissolve, and the activity is easy to lose when it is hot; the pH value needs to be adjusted, and different additives have appropriate acid and alkali environments, such as grass and wood when it rains, and each has its place.
In short, with Retention Aid, when using the ancient papermaking prudent attitude, check the material, control the dosage, choose the opportunity, and take into account the environment, so that you can get good paper, and make good use of this agent.

How Effective Retention Aid Is in Different Settings
Retention Aids are also related to the retention of pulp fibers in the papermaking industry, which affects the quality of paper products greatly. Its effect varies depending on the environment, and the following is a trial discussion.
In a warm and humid environment, the molecules of retention aids are active and can quickly interact with fibers and fillers. For example, in a warm and moist place in the south of the Yangtze River, in a summer workshop, the air humidity is about 60%, and the temperature is around 25 ° C. Retention aids can adhere to fibers and fillers by means of hydrogen bonds, electrostatic attractive forces, etc. At this time, the fiber network structure is stable, the filler is not easy to dissipate, and the paper product has good uniformity and strength. Looking at the handwritten sheet, it can be seen that the fibers are evenly distributed, without agglomeration or vacancy, and the burst resistance and tensile strength are good.
However, if the environment is dry, such as the paper mill in the northwest desert, the air humidity is often less than 30%, and the molecular diffusion of the retention aid is limited. Although the dosage is as usual, it is difficult to fully combine with the fibers and fillers. The bonding force between the fibers is weak, the filler is easy to lose, the uniformity of the paper is poor, and the strength is also reduced. The copied paper has visible holes and spots, which are easy to break when used.
As for high temperature environments, such as tropical regions, where the temperature exceeds 35 ° C, the stability of the retention aid is challenged. Its molecular structure may change and its activity decreases. At this time, it is difficult to add the retention aid to achieve the expected retention effect. Fibers and fillers are easy to flow away with water. The net part of the paper machine filters water quickly, but the retention rate is low. The paper products produced are uneven in thickness and poor in physical properties.
In the high-salt environment, if the coastal paper mill uses seawater treatment or recycled water with high salt content, salt ions and retention aids compete for the check point on the fiber surface. The adsorption amount of retention aids is reduced, and the retention function is greatly reduced. The retention of fillers in paper products is less, which affects whiteness and opacity, and the stiffness of paper products is insufficient due to poor fiber bonding.
From this perspective, environmental factors have a profound impact on the effectiveness of Retention Aid. Operators should observe changes in the environment and adjust the selection, quantity and use of retention aids in a timely manner in order to achieve optimum results and produce high-quality paper products.

What are the advantages of Retention Aid compared to other similar products?
Retention Aid, in the art of papermaking, is also an auxiliary for increasing fiber retention. Compared with other similar products, it has a number of advantages.
First, efficient retention can make fibers and fillers better retained when the paper is formed. Like the ancient sieve, a fine sieve can keep small things, and Retention Aid is like a delicate sieve, which allows more papermaking raw materials to be retained on the paper, improving the strength and evenness of the paper product. Other materials may be kept inefficient, resulting in the loss of raw materials and poor quality of the paper, and Retention Aid can avoid this risk.
Second, good filtration assistance. In the papermaking process, dehydration is essential, which can promote water to quickly separate fibers and fillers, such as a boat traveling in water, unimpeded. Compared with other products, it may cause dehydration to be slow, and paper drying is time-consuming, while Retention Aid makes water filtration efficient, improves papermaking efficiency, and saves energy consumption, just like a good boat helps a boat to run quickly.
Third, stabilize the operation of the paper machine. It can reduce the disorder of fiber flocculation and make the fiber distribution uniform. In the operation of the paper machine, it is like a stable car, which is smooth and smooth. If other things make the fibers disordered, it is easy to cause the paper machine to fail and damage the equipment, while Retention Aid keeps the paper machine stable and protects its long-term operation.
Fourth, it has a wide range of adaptability. It can be compatible with a variety of papermaking chemicals, such as the ruler of medicine, and coexist harmoniously to promote the improvement of paper products. Compared with other products, or with other things, the effect is difficult to show, while Retention Aid is widely compatible and can play a good role in the papermaking system.
In summary, Retention Aid has significant advantages in papermaking compared with other similar products in terms of retention, filter assistance, machine stabilization, compatibility, etc., and is a good choice for the papermaking industry to improve quality and enhance efficiency.

What is the shelf life of Retention Aid?
The shelf life of Retention Aid is also related to the usable time limit of this object, which is extremely important. However, if you want to know the geometry of its shelf life, it cannot be directly referred to in "Tiangong Kaiwu".
"Tiangong Kaiwu" is a collection of ancient Chinese craftsmanship and technology. The book details the methods of creation and the properties of materials. However, the name of Retention Aid is not its inherent title, so it is difficult to find the exact record of its shelf life.
Although the ancient craftsmanship is not explicitly stated in the word "shelf life" today, it also has an understanding of the timeliness of materials. In terms of material preservation, the ancients were well aware of the influence of many factors such as environment and season. For example, certain ingredients, pigments, fabrics and other materials are properly stored according to the season and climate, so as to prolong their availability.
In ancient creations, materials are used in a timely manner, and the quality is changeable over time. If it is a common sense, if Retention Aid is a type of auxiliary retention material, its shelf life should depend on its material, production process and storage conditions. If it is made of grass and wood, or the shelf life is short due to perishability, it may vary from several months to half a year under suitable storage conditions; if it is refined with gold and stone, its properties may be stable, and the shelf life may be slightly longer, or up to several years. However, these are all speculative words, because there is no exact basis for "Tiangong Kaiwu", it is difficult to determine its accuracy. In general, in order to know the exact shelf life of Retention Aid, it is necessary to study it carefully according to its specific material, production and preservation. It cannot be hidden by ancient books.
