Fluorine leather acid what is the main use

Fluoroleatheric acid is a special substance made by chemical industry. It has a wide range of uses and is very useful in the field of leather.

First, it is used in the leather tanning process. Tanning is a key step in leather manufacturing. Fluoroleatheric acid can be tightly combined with leather collagen fibers to strengthen the structure of leather. In this way, the physical properties of leather are greatly improved, such as toughness and wear resistance. The leather treated in this way can resist external friction and wear, and the durability is also extended.

Second, in the waterproof treatment of leather, fluoroleatheric acid is also indispensable. Its special chemical structure can form a fine waterproof film on the surface of leather. This film not only does not hinder the leather's breathability, but also effectively blocks moisture intrusion, so that the leather can remain dry in a humid environment and maintain good texture and performance.

Third, in the anti-fouling aspect of leather, fluoroleatheric acid exhibits unique performance. It can reduce the surface energy of the leather surface, making it difficult for stains to adhere to it. Even if stained, it is also easy to clean, greatly improving the daily maintenance convenience of leather, making leather products clean and beautiful for a long time.

Fourth, fluoroleatheric acid can improve the softness and feel of leather. Adding it during leather processing can make leather fibers looser and smoother, giving leather a soft and comfortable touch, and improving the quality and experience of leather products.

In conclusion, fluoroleatheric acid plays an important role in tanning, waterproofing, anti-fouling, and improving the feel of the leather industry, greatly enhancing the quality and performance of leather products and meeting the world's growing demand for leather products.

Fluorine leather acid performance characteristics

Fluorotannic acid is unique in its properties and has various characteristics.

The first word about its tanning property. Fluorotannic acid has outstanding performance in leather tanning. It can make leather dense and flexible in texture. If it is tanned by ancient methods, leather may be stiff and brittle, but if it is tanned by fluorotannic acid, the leather surface is smooth and delicate to the touch, just like the smoothness of silk. The cover can penetrate into the leather fibers because of its exquisite molecular structure, tightly combine and strengthen the connection of the fibers, so that the leather has good physical properties, greatly increased tensile strength and durability.

Times and chemical stability. Fluorotannic acid has high chemical stability and is not easy to be eroded by ordinary chemical reagents. In the acid and alkali environment, it can be stable in the middle and does not easily undergo chemical reactions. This property makes the leather tanned by it resistant to the influence of external chemicals. If it is in a humid and acid-containing atmosphere, it is also difficult to be corroded. The color and texture of the leather remain unchanged for a long time, just like the ancient golden stone, which will not be damaged over time.

In addition, the waterproof performance is outstanding. The leather treated with fluorotannic acid has excellent waterproof properties. Raindrops fall on it, like lotus leaves exposed, naturally tumbling down and not soaking. This is because fluorotannic acid builds a fine layer of protection on the surface of the leather, making it difficult for water molecules to enter. In this way, the leather can be kept dry and dry in the wet environment, and the function is not damaged. It is like the water repellent of a sewing coat, and the leather is intact.

It also has the ability of antibacterial and antimildew. Fluorotannic acid contains special chemical groups, which can inhibit the growth of bacteria and molds. In warm and humid places, leather is often prone to mildew and rot. However, when tanned with fluorotannic acid, it can be kept clean for a long time, without the disturbance of mildew bacteria. It is like an ancient secret, hidden in a secluded room without beetling.

Fluorotannic acid occupies an important position in the field of leather tanning due to its good tanning properties, chemical stability, water resistance and excellent antibacterial properties. It is a key element for leather quality improvement.

Fluorine leather acid production process is how

The production process of fluorotannic acid is quite complicated. At the beginning, excellent raw materials are required, and fluoride and specific leather materials must be selected accurately, which is related to the quality of the finished product.

The first step is raw material pretreatment. Carefully wash the leather to remove its dirt, grease and other sundries, so that the leather fibers can stretch and pave the way for subsequent reactions. Fluoride also needs to be purified and refined to ensure that the purity is up to standard, so as not to interfere with the reaction process due to impurities.

Second rule, tanning reaction. In a special reactor, the pretreated leather and fluoride are put into a precise ratio, accompanied by a suitable catalyst, to control the temperature, pressure and reaction time. Among them, the temperature needs to be fine-tuned according to the characteristics of the leather and the fluoride, usually fluctuating in a specific range, in order to promote the full combination of the two, build a stable tanning structure, and give the leather its unique fluorine tanning characteristics, such as excellent waterproof, oil-proof and wear-resistant properties.

Furthermore, the post-processing process. After the reaction, the leather needs to be washed several times to remove unreacted fluoride and by-products, in order to prevent the residue from affecting the quality of the leather and the environment. Then the treatment such as neutralization and refueling is applied to soften the leather fibers, restore their softness and fullness, and improve their feel and appearance.

Finally, the packaging is tested. The tanned leather is tested according to strict standards, covering physical properties, chemical indicators and other dimensions. After all the indicators meet the requirements, they are carefully packaged to prevent damage during transportation and storage. At this point, fluorotannic acid leather is made and can be used in the market for a variety of purposes.

Fluorine leather acid in the use of what are the precautions

Fluorotannic acid is also a chemical used in leather tanning. When using it, be sure to pay attention to many things in order to achieve proper results and ensure safety.

First, protection is of paramount importance. Fluorotannic acid has certain corrosive and irritating properties. In contact with it, protective equipment must be worn, such as acid and alkali resistant gloves, protective glasses, protective clothing, etc., to prevent the agent from touching the skin and eyes and causing burns. In case of inadvertent contact, rinse quickly with a lot of water and seek medical treatment if necessary.

Second, precisely control the dosage. The dosage of fluorotannic acid must be accurately calculated according to the specific requirements of the type, quality and tanning of leather. If the dosage is too small, the tanning effect is not good, the leather is easy to stiffen and lack toughness; if the dosage is too large, it will only increase the cost, and may affect the color and texture of the leather, which will also cause a greater burden on the environment.

Third, pay attention to the operating environment. The operation should be carried out in a well-ventilated place to prevent the accumulation of volatile gas from the agent and damage human health. If conditions permit, ventilation equipment, such as exhaust fans, can be installed to facilitate the discharge of harmful gases.

Fourth, properly dispose of the waste liquid. The waste liquid generated during the tanning process contains fluorotannic acid and other impurities, and should not be discharged at will to avoid polluting the environment. It must go through a special sewage treatment procedure to reduce the content of harmful substances in it to below the specified standard before discharge.

Fifth, strictly follow the storage specifications. Fluorotannic acid should be stored in a cool, dry and ventilated place, away from fire and heat sources, and must be stored separately from oxidants and alkalis. Do not mix storage to prevent chemical reactions and dangerous accidents. At the same time, obvious warning signs should be set up in the storage place for personnel to identify.

Fluorine leather acid compared to other similar products

Compared with other similar products, fluoroleatheric acid has many advantages. First, it has excellent corrosion resistance. Fluoroleatheric acid contains fluorine elements and forms a special molecular structure. It can be stable in various chemical environments and has excellent resistance to many corrosive media, such as strong acids and alkalis. Compared with other products, in places prone to corrosion, the leather protected by fluoroleatheric acid lasts for a long time, does not damage the texture, and does not fade.

Second, it has excellent waterproof and oil repellent performance. Fluorine atoms have high electronegativity and low molecular surface energy, making the leather surface water-repellent and oil-repellent. Water droplets and oil droplets fall on it, which are difficult to penetrate and adhere, and roll straight down. And other similar products, or lack of waterproof, or oil easily contaminated, resulting in leather stains difficult to clean. Fluoroleather acid makes leather always dry and clean, easy to maintain.

Third, outstanding wear resistance. Its molecular structure is tight and strong, giving leather good wear resistance. After frequent friction, it also shows less wear and fluff. Compared with other products, the wear resistance is short, and the leather surface will be scarred soon after use, affecting the appearance and durability.

Fourth, the stability is extremely high. No matter the high temperature and heat, or the low temperature and cold, fluoroleather acid can maintain its stable performance. Unlike some products, it becomes soft and deformed at high temperature, and it is brittle and hard and easy to crack at low temperature. Under a variety of climatic conditions and environments, it can protect the leather and maintain the quality and appearance of leather for a long time.

It can be seen that fluoroleather acid has significant advantages over other similar products in terms of corrosion resistance, water resistance and oil resistance, wear resistance and stability. It is a good choice for leather protection.
