What are the main components of Flame Retardant KFS?
Flame Retardant KFS is a widely used flame retardant in today's world. Its main ingredients, ancient and modern research, are mostly phosphorus-based and nitrogen-based compounds, supplemented by inorganic fillers. Its core should be mainly phosphate esters, or ammonium phosphate, urea phosphate, or both ammonium polyphosphate. These drugs are highly flame retardant, often combined with polymer materials, can significantly improve their fire resistance. Phosphorus flame retardant, in case of fire can form a layer of carbonized film on the surface of the material, blocking oxygen gas, stifling the flame edge. If nitrogen coexists, it can release nitrogen when burned, dilute the flammable gas, and re-energize to cool the flaming body, synergistic effect, double magic. In addition, the flame retardants under the name of KFS often contain intumescent additives, which bubble when heated to form a honeycomb-like intumescent layer, which is very good for suppressing the spread of fire. Melamine, quaternary ammonium salts and other substances are also introduced during this period, which can not only thicken the intumescent layer, but also strengthen corrosion resistance and stability. Then take silicon, inorganic oxides such as antimony trioxide, aluminum hydroxide, etc., or help heat stability, or build a fire barrier.
This method is tested, and more in accordance with the purpose of green environmental protection, to remove toxic elements such as bromine. KFS has then moved towards the path of phosphorus and nitrogen halogen-free, and has advanced with new materials. Its production requires the inspection of pure materials, the fine review of the synthesis conditions, and the maintenance of appropriate particle size, so that it can be integrated into the resin and coating, and applied to the fields of textiles, plastics, and coatings, all of which can be long-term flame retardant and safe to apply. Overall, the main components of KFS flame retardants, when they are multi-phosphorus and nitrogen compounds, supplemented by inorganic additives, are synergistically expanded, and can meet the fire resistance needs of fibers, plastics, coatings, etc., and the results are recognized.
What materials is Flame Retardant KFS suitable for?
Flame Retardant KFS is made by this world's craftsmanship, mainly to improve the fire resistance of various materials, so that they can be exposed to flames, delay combustion, and reduce damage. According to its nature, it is compatible with many qualities and can be applied to a variety of items. All wood, paper, and textile products can be blessed by it. Wood is taken from forest trees. Although the texture is strong, if it encounters flames, it will quickly extinguish. KFS is applied to wood, which can penetrate its fibers, prevent the penetration of oxygen and heat, and greatly slow down the rate of combustion. Paper is light and thin, and it is easy to burn. If KFS penetrates, it is difficult to spread the fire. Textiles, or cotton, linen, silk, and wool, are easy to burn due to their loose fibrous structure. If they are coated with KFS, they will form a film on the surface and penetrate inside. When encountering flames, it will be difficult.
In addition, some polymer materials, such as polyethylene, polypropylene, polyamide, etc., although they are self-combustible in nature, they have to be treated with KFS to increase their fire resistance. This is composed of various components in KFS, which form a carbonized layer at high temperature, effectively blocking air and heat flow, inhibiting the escape of combustible gas, not delaying the ignition time of the material, and greatly reducing the generation of smoke and harmful gases. It is also suitable for rubber, foam, paint, etc. Its composition is mostly organic matter, which is easy to be burned. Using KFS to penetrate the surface layer can enhance its flame retardant effect.
Looking around, all those who need to delay the spread of flames, such as building materials, vehicle interiors, home textiles, and packaging materials, can apply KFS. Its usage is either impregnated, sprayed, or mixed in raw materials. The additional teaching materials are different in quality, and they are matched with different methods to make its flame retardant effect the most significant. In short, Flame Retardant KFS is suitable for wood, paper, cloth, polymer compounds, rubber, foam and various organic products. It is a powerful tool for fire protection in this world.
How to use Flame Retardant KFS?
"How to Use Flame Retardant KFS"
Flame Retardant KFS is also a good anti-flame agent. Anyone who wants to use this must first recognize its nature, know its suitability, and do not use it indiscriminately. At the beginning, the utensils or fabrics are ready, clean and dust-free, and can only be applied. If there are dirt impurities, it must be washed first, cleaned, dried, and then the agent can be used. Prepare a purifier for the second time, pour an appropriate amount of KFS flame inhibitor into it, and dilute it with water. The proportion is according to the needs of the material, or follow the manufacturer's instructions, and the mixture is uniform.
Apply it to the surface by means of a brush, spray, or dipping. Brush, when evenly back and forth, without leaving dead ends, leaving no traces. Sprayer, the distance is moderate, not too close, nor far away, so that the fine mist of the medicine is evenly distributed throughout the whole. For those who are impregnated, put the object into the liquid and soak it to a certain extent, but not for too long, to prevent damage to its texture. Each method must be applied evenly, preferring more than less. After applying, leave it in a ventilated place, not near an open flame or high temperature, and wait for it to dry naturally in the shade. If you encounter a heavy device, apply it several times, and then apply it again after each dry, until the liquid is completely adsorbed.
To test its performance, you can take a small piece of micro-test, and use it near the fire. If it does not burn or self-extinguish, it will be effective. If not, when repeated once, until it meets the requirements. Although KFS is good, it is not permanent. Every time it is washed, the flame resistance or reduction should be repeated in sequence. When storing the flame prevention agent, it should be sealed, protected from heat and light, and not mixed with acid and alkali debris. The utensils used should be carefully washed, and the residual liquid should not be discarded in the flow channel to protect the environment.
When using this agent, be careful not to enter the mouth and eyes. Operators should wear gloves and masks to ensure safety. The application is especially careful for children and infants. In short, the use of KFS to prevent flames focuses on proper, uniform and safe application. It is also effective to apply it carefully.
What is the flame retardant rating of the Flame Retardant KFS?
Flame Retardant KFS is a material made by modern technology to prevent the spread of flames. Its flame retardant grade, according to international standards, is mostly based on UL 94, GB 20286 and other specifications. KFS has been tested and can often reach UL 94 V-0 grade, which means that in strict tests, after the material is burned for a short time by the flame, the self-extinguishing time is very short, and there is no dripping of the combustion material, and there is no risk of flame spread. These grades are the top grade of many flame retardant materials, suitable for high safety requirements, such as aviation, transportation, construction and electronic devices.
Flame retardant standards, to name a few. UL 94 is a plastic flammability test method stipulated by a well-known safety inspection agency in the United States. V-0 is the highest flame retardant category, and the second is V-1 and V-2. The meaning of V-0 is: after the sample is irradiated with the specified flame, it must self-extinguish within ten seconds twice, and the total burning time should not exceed fifty seconds. It must not have the appearance of fire droplets igniting cotton. The Chinese standard GB 20286 is mostly classified as B1 and B2. B1 is the flame retardant grade, and B2 is the flammable grade. KFS can be placed in the B1 category, showing its excellent flame retardant performance.
The flame retardancy of such materials is due to the addition of flame retardants, forming a heat insulation carbon layer or releasing products that inhibit free radicals, interfering with the combustion chain reaction and blocking the flame spread. The combination of the material's own components and the flame retardant process is excellent, which can ensure daily safety in principle, and it is not easy to lose the flame retardant instinct due to high temperature.
However, although such materials have high flame retardant standards such as V-0 and B1, they still need to be comprehensively considered in special environments, such as smoke density, toxic emissions, long-term aging and weather resistance. Scientific research is changing with each passing day, and its performance can be further optimized. Today's Flame Retardant KFS has been favored by many projects, and is found in high-speed rail, subway, aircraft, data center and other important places.
Overall, the flame retardant rating of the Flame Retardant KFS can reach UL 94 V-0 or GB 20286 B1, which is truly the best in the industry and is of great benefit to safety.
Is Flame Retardant KFS harmful to the environment and human health?
Fire retardant KFS is a chemically synthesized material used to slow down or inhibit the rate of combustion of substances. Some commentators say that this material can prevent fires, protect life and property, and may be suspected of causing damage to the environment and human body. Today, about 500 words are used in the text to study the rationale for reference.
Fire retardant KFS contains mostly compounds of bromine and phosphorus, or more mixed with organic polymers. It has strong chemical properties and can prevent the chain reaction of combustion. Although the industry calls it comfortable, those who carefully observe it in the environment and the human body have real concerns. It is used in plastics, fibers, homes and other utensils, and it is widely used, making it difficult to contain its residue or infiltrate into the air, water and soil. Accumulated over time, easy to drift with dust, or infiltrate rivers, ponds and marshes. Fish, insects and plants are disturbed by it, and the ecology is lost. Those who eat and accumulate to the upper part of the food chain, and the residual poison can be reversed.
In the human body, the fire inhibitor KFS can be ingested by breathing, skin contact, or diet. Return to the same place all three ways, invading the internal organs. Modern medicine has tested that the fire inhibitor KFS accumulates in the body, often impairing liver and kidney function, or causing endocrine disorders. Long-term exposure may interfere with immunity, and even induce tumors. When a woman is pregnant and an infant grows, it is fragile, and the toxicity may be more pronounced.
Of course, it should be clear that the fire retardant KFS has the purpose of protecting fire protection and can actually save lives and property. However, to take advantage and avoid harm, it is especially necessary to weigh. Nowadays, in Europe and the United States, the use of flame retardants containing bromine and phosphorus has been gradually restricted, promoting green environmental protection, and exploring new bio-based fire retardant materials. It is because of scientific progress and environmental sanitation first, and it cannot be obtained occasionally for convenience, and the long-term damage can be left behind.
Although the fire retardant KFS can help first aid fires, its damage to the environment and human body cannot be ignored. If you want peace, it is appropriate to develop harmless new materials, manage them properly, and use them prudently. Tens of thousands of things are safe, and the environment is not replaced, and people are also
