What is the scope of application of medium temperature fluorine-free sealant?

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. Its words are simple and detailed, and it is well explained in all kinds of skills. This answer to the question of the scope of application of the medium temperature sealant is in line with the ancient classical Chinese style.

The medium temperature sealant without sealant is unique and suitable for many scenarios. It is first suitable for the sealing of mechanical appliances. For all kinds of equipment, such as the machines used in workshops, smelting furnace equipment, etc., where the parts are connected, a leak-proof seal is often required. The medium temperature sealant can be used in the middle temperature environment to ensure that there is no risk of fluid leakage when the equipment is running, to ensure its smooth operation, not to damage the equipment due to leakage, and not to affect the process.

Furthermore, it is also useful in building construction. Where the beams of the house are handed over, the doors and windows are combined with the wall, this sealing paste can be used to prevent wind and rain invasion and moisture penetration. In a medium temperature environment, it can maintain the sealing effect for a long time, make the residence stable, avoid the suffering of wind and rain leakage, and protect the building structure and prolong its life.

And the chemical industry is also suitable for it. In chemical production, pipeline connection, reactor sealing and other links need to withstand a certain temperature and seal well. Medium temperature non-sealant paste can ensure that chemical substances do not leak out under medium temperature conditions, ensure production safety, and maintain the stable progress of chemical reactions. It will not cause accidents due to leakage, which will damage production and the surrounding environment.

In addition, vehicles, ships and other means of transportation also have their uses. Vehicle engine parts are sealed, and the connection between the ship's cabin and deck is sealed. Under medium temperature operation, this sealing paste can effectively waterproof, dustproof, and oil and gas leakage, ensuring the performance of transportation tools, so that they can safely gallop on land and in rivers and seas.

What are the performance characteristics of medium temperature fluorine-free sealant?

Medium temperature oil-free sealing grease, with a number of performance characteristics. Its first good adhesion, can adhere tightly to the surface of various materials, just like paint attached to wood, although over time and external force, it is difficult to peel off, can ensure that the seal is stable for a long time.

Furthermore, its sealing power is outstanding. In the middle temperature environment, it can tightly fit and block the leakage of gases and liquids, just like a strong city to defend against the enemy, so that the inside and outside are separated, eliminating hidden dangers. And this fat is chemically stable, not afraid of the erosion of common chemical media, such as in the field of acid and alkali, it can also be calm, without damaging its quality, and the sealing effect is as good as ever.

And lubricity is also its long. It can reduce the friction between components, make the operation smooth, like a boat traveling on water, unimpeded, reduce wear and tear, and extend the life of the equipment. At the same time, it has good temperature resistance, in a medium temperature environment, does not flow or flow, maintains the inherent form, and can change at a certain temperature without losing its ability to seal and lubricate, such as pine and cypress through cold and heat and evergreen.

In addition, this grease is clean and oil-free, does not stain the periphery, and is suitable for places that require cleanliness, just like a gentleman's high cleanliness, does not stain dust, and keeps the environment and equipment clean. And its anti-aging properties are good. After years of circulation, the performance is slightly weakened, and it protects the stable operation of the equipment for a long time. If the rock is strong, it will last for a long time.

What are the advantages of medium temperature fluorine-free sealants compared with other sealants?

Compared with other sealing greases, the advantages of medium temperature halogen-free sealing grease are mainly reflected in the following ends:

First, the heat resistance is quite good. Medium temperature halogen-free sealing grease can maintain stable performance in a certain medium temperature range, and is not easy to flow and soften due to temperature increase, which can effectively ensure the sealing effect of the sealing part in the corresponding temperature environment. For example, in some industrial equipment, the temperature often fluctuates. Medium temperature halogen-free sealing grease can play a lasting and stable sealing effect by virtue of its good heat resistance, avoiding sealing failure due to temperature changes, thereby preventing the leakage of the internal medium of the equipment and ensuring the safe and stable operation of the equipment.

Second, halogen-free characteristics are extremely critical. In today's society, more and more attention is paid to environmental protection. Halogen elements may release harmful substances under specific conditions, causing potential harm to the environment and human health. The medium temperature halogen-free sealing grease does not contain halogen elements, which meets the requirements of environmental protection concepts and related standards. When applied in industries with strict hygiene and environmental protection requirements such as food and medicine, it can effectively avoid the possible pollution risks caused by halogen elements and ensure product safety and environmental friendliness.

Third, good sealing performance. It has suitable consistency and adhesion, can closely fit the sealing surface, fill tiny gaps and holes, and effectively block the leakage of gas, liquid and other media. Whether it is static sealing or dynamic sealing scenarios, it can provide reliable sealing protection. For example, in pipeline joints, mechanical seals, etc., a stable sealing layer can be formed to prevent media from seeping out and maintain the normal operation of the system.

Fourth, excellent chemical stability. Medium temperature halogen-free sealing grease has good resistance to most chemical substances and is not easy to chemically react with surrounding media. In the face of different chemical environments, it can maintain its own physical and chemical properties stable and not be corroded or dissolved. This makes it widely used in a variety of complex chemical environments, such as chemical production equipment, sewage treatment facilities, etc., to prolong the service life of equipment and reduce maintenance costs.

What is the construction process of medium temperature fluorine-free sealant?

"Tiangong Kaiwu" has a saying: "The medium temperature seamless and dense coating of paint is quite ingenious." The implementation of this process has many subtleties.

The first is the selection of materials, and the high-quality paint must be taken. The quality of the paint is related to the texture of the finished product. The paint liquid needs to be pure and free, and the color should be warm and moist, which can be used as the base. And when choosing the paint, check its viscosity, drying speed and other characteristics, which are closely related to the effect of the process.

As for the maker, first shape it with good materials, and its shape must be regular and the size is accurate. Then, apply primer all over the surface of the device. This step needs to be evenly and thinly coated, and wait for it to dry slowly. This is the key to ensuring that the paint surface is flat.

The key to a seamless package lies in the treatment of the splicing place. The craftsman uses exquisite skills to make the parts connect without marks. Or use the method of mortise and tenon to fit tightly; or apply special adhesives to make it strong and lasting. The joints are repeatedly polished and painted until they are seamless and there is no sign of cracks.

Then baked at medium temperature, temperature control is extremely important. If the temperature is too high, the paint is easy to dry and crack; if the temperature is too low, the paint is difficult to dry and form. The craftsman relies on experience and keen perception to make the temperature just right, so that the paint is firmly attached to the utensils, and the color is bright.

Finally, paint many times, each time you need to wait patiently for drying, and then polish carefully. In this way, it is possible to achieve the best dense lacquer. Its surface is as smooth as a mirror, with delicate texture, both practical and ornamental, and it shows the superb craftsmanship of medium temperature seamless dense lacquer.

What are the storage conditions for medium temperature fluorine-free sealant?

Medium temperature oil-free sealing grease is used in industry. Its storage conditions are related to performance and lifespan, and it is crucial. According to the method of "Tiangong Kaiwu", it should be described in detail in the ancient method.

First, the temperature, this grease should be stored in a cool place, and the temperature should not exceed 30 degrees Celsius. High temperature is easy to change the properties of the fat, and its viscosity and consistency are changed. If used, the efficacy is greatly reduced. If exposed to the hot sun, or in a room with high temperature, the components in the fat may evaporate or decompose, and its sealing ability gradually loses.

Second, in terms of humidity, it should be placed in a dry place and avoided in a humid place. If the moisture is heavy, the water vapor enters the fat, or causes it to deteriorate and cause corrosion. Metal parts in contact with it are prone to rust and damage the sealing quality. Therefore, the storage place should be supplemented by moisture-absorbing substances such as lime and charcoal to keep it dry.

Furthermore, anti-pollution is also necessary. This fat should be sealed and stored to prevent external impurities from invading. Dust and debris enter the fat and disturb its structure, which may cause the seal to be lax when used. The utensils containing fat must be clean and intact, and when used, the tools must also be cleaned to avoid staining their quality.

Also, the storage place should be shock-proof. Vibration can easily make the internal structure of the fat loose, the components are separated, and its uniform state is lost. Long-term vibration makes it difficult to restore the performance of the fat as before.

And this fat should not be mixed with other substances. Different types of fats have different compositions, and mixing may cause chemical reactions, which will damage their quality. It must be placed in a separate place and clearly marked to avoid misuse.

The storage of medium temperature oil-free sealing grease must be in accordance with the above articles, temperature control, dehumidification, anti-fouling, shock absorption, and separate storage, so as to ensure its excellent performance and prepare it for industrial needs.
