What are the main uses of Proban THPC?
Proban THPC, the name of the chemical agent is also the scientific name of tetrahydroxymethyl phosphate chloride. Its clear and colorless, slightly ammonia-like, soluble in water, often used in the textile industry, especially flame retardant. In ancient times, plants and trees were used as clothing, and fires were frequent. The change of fire was feared by many. Since the rise of chemistry, skilled craftsmen began to develop pharmaceuticals to control fire, and THPC became famous in the world.
What is its function? Fire prevention is the first. Today's clothes and quilts are mostly made of cotton, and the cotton body is easy to burn, and in case of fire, it will be intense, and it will be ashes in an instant. THPC solution is stained into the fabric, and through a special process, the medicine is deeply penetrated into the fibers, and then reacted with organic reactions to form a flame-retardant layer on the surface of the As soon as the flame of the husband arrives, it will break when it encounters the medicine, and it will be difficult to spread, and the people will be safe. It is because of this agent that the flame retardant cloth of Proban technology can be made. It can be taken close to an open flame, and it is not afraid of charcoal flames. Fire protection, military police, factories, and experiments use Rice agent.
The way of THPC is not only in clothing. It can be used for wood, paper, and plastic. The wood board is painted with this medicine, and it is shaped at high temperature. When the fire encounters the surface, it is charred into a shell, which will not burn out, and can keep the house safe. Paper is made, and it is often afraid of fire. If this agent is used, it is printed into rolls, and it must be preserved for a long time. The production of plastic is highly flammable, but it is only possible to
If you use this agent, you need to operate it with caution. Its properties are corrosive, the muscles are damaged, the mist enters the eyes, or the disease occurs. When operating by craftsmen, you must wear gloves to protect your eyes, and take all kinds of precautions as the first. The residue of the medicine must not flow into the rivers, for fear of harming life. This agent is hereby used to benefit the national economy and people's livelihood, and to protect all ecological things.
To sum up, Proban THPC is a good flame retardant agent, especially in textiles. Make it shorter than safe, so that all things are far from fire, beneficial to the present and benefit future generations.
What are the chemical components of Proban THPC?
Proban THPC is actually a commonly used flame-resistant finishing agent in the textile industry. Its main chemical composition is tetra (hydroxymethyl) phosphonium chloride, and its molecular formula is [ (HOCH -2) P] Cl. Its white solid, soluble in water, is very stable. Since the 1960s, Western countries have introduced this as a fireproof fiber, and it has gradually become more and more important in the world.
The properties of tetrahydroxymethyl phosphate can react with cellulose fibers. After appropriate treatment, it has a very stable network structure between fiber molecules. This structure can effectively block the transmission of combustion reactions, making it difficult for cloth to be quickly burned in case of fire, so it is widely used in the refractory finishing of cotton textiles. The reaction process often requires the addition of dimethyl sulfoxide and other additives, and goes through ammonia treatment and oxidation processes to eventually form a washable and durable flame retardant product.
Proban THPC finishing still needs to react with formaldehyde in order to strengthen its chemical bonds. However, formaldehyde is volatile and needs to be carefully controlled to prevent harm to the human body. Its chemical mechanism is to borrow the non-flammable properties of phosphorus to form an expansive carbon layer during combustion, isolating air and inhibiting the spread of flames. And because THPC decomposes and releases non-toxic gases, it is environmentally friendly, which has the advantages of safety and efficiency compared with flame-resistant agents such as bromine and chlorine.
However, if THPC is used in excess or the waste liquid is not handled properly, there is a risk of polluting the water body. Therefore, its use and disposal must be controlled and not arbitrary. Textile technology has advanced, expanding from chemical fire protection to green, healthy and low-emission methods. Although THPC is effective, it also needs to be supplemented by new environmentally friendly materials.
Tracing its chemical nature, THPC is a quaternary phosphorus salt. Its tetrahydroxymethyl structure imparts good hydrophilicity, making it easy to process and apply to cotton fabrics without compromising its flexibility and luster. It is no accident that THPC can be used as a safe and fireproof finishing agent in fire protection standards in many countries today. Following ancient times, it is a great thing for humans to use chemicals for daily use, and Proban THPC is really one of the examples of this.
What are the storage requirements for Proban THPC?
Proban THPC is an important additive in textile printing and dyeing, and is often used to improve the flame retardant properties of fabrics. It is violent and easy to react with air or moisture, so it should be stored carefully. When storing this agent, abide by the essentials of numbers and should not be ignored.
First, the choice of utensils. As long as it needs to be stored in a closed container, it should not meet metal containers such as iron, aluminum, and copper. It should be sealed with plastic or glassware. If it encounters metal, it may react or cause corrosion, which will damage its purity and even deteriorate. The container must be strong and crack-free, and should not be placed in a place that is out of repair and damaged.
Second, the environment is appropriate. It should be stored in a cool and dry room, away from fire, heat, and direct sunlight. If there is no degree of temperature and humidity, Proban THPC may be easily decomposed due to high temperature, or differentiated due to water vapor. Therefore, the temperature between the storage rooms should be 5 degrees Celsius to 30 degrees Celsius, and the humidity should be relatively low, so as not to get damp. Daily inspections are required to ensure that there is no leakage or water seepage.
Third, keep foreign matter away. Do not mix with oxidizing agents, acids, reducing agents and other chemicals, otherwise there may be chemical reactions that affect storage safety. All those that are flammable and corrosive must be avoided to avoid cross-contamination.
Fourth, ventilation needs to be prepared. The air in the storage room is smooth and well ventilated. Prevent odor accumulation, and also prevent evaporation after leakage from endangering health. It is equipped with protective facilities to keep unrelated people away. In case of accidental escape, it should be rinsed with a large amount of water to allow air circulation and quickly move the situation.
Five days, the logo is clear. On the utensils, there should be obvious signs indicating the stored species, batch number, production date, etc. To prevent misuse and misuse, and to facilitate inspection and traceability.
Six days, regular inspection. Where it has been stored for a long time, it should be checked regularly to see if its color and odor are abnormal and whether the texture has changed. If there is deterioration, crystallization, precipitation, etc., it should be dealt with in time, so as not to enter production.
Close the above meanings, the Proban THPC can be stored safely for later use.
What are the safety precautions for Proban THPC during use?
Proban THPC, one of the chemicals used for flame retardancy of fibers. It is very strong and decomposes when heated, escaping toxic gases. When using it, caution should be taken. The safety precautions described here are listed below:
At the beginning, the storage should be in a cool and ventilated place, away from fire sources and high temperature objects to prevent spontaneous combustion. The container should be sealed so as not to leak, so as not to contact it with air moisture, it is prone to deterioration. And do not store with oxidizing agents, reducing agents and strong acids and alkalis to avoid reaction damage.
Secondly, when taking it, you should wear protective equipment such as gloves, goggles and gas masks. Do not touch it with bare hands. If it is accidentally splashed on the skin, rinse it with water in an emergency, and do not delay. If it is not careful to enter the eye, rinse it with a large amount of water and seek medical attention quickly. The workplace should be equipped with emergency flushing facilities to prevent it.
And its vapor or dust enter the body, which is very harmful. The working area must be equipped with a good exhaust device, so that harmful gases must not accumulate. If conditions permit, choose a fully enclosed operation to prevent the liquid from escaping. The operator must be specially trained and know the harm before acting as a deacon.
Every splash or leak, immediately collect it with an inert adsorbent, and then store it in a special container, until it is concentrated and harmless. After disposal, the utensils and the ground must be thoroughly washed to remove residues. Waste liquid disposal should be handled in accordance with relevant national regulations, and should not be allowed to enter rivers and pollute the environment.
After use, the clothes should also be changed in time, and the stains on the body should be cleaned. Chemicals are easily contaminated and injured, so it is advisable to be cautious and cautious. In case of discomfort, go to the hospital for treatment quickly, and do not underestimate future problems. If an accident occurs during transportation, you should also act according to the emergency plan and report it to the relevant departments for guidance.
In short, ProTHban PC is harmful, and anyone who comes into contact should follow safety procedures. Avoid it by chance, be careful with its operation, and protect yourself, which will also benefit others.
How is Proban THPC discarded?
Proban THPC, actually tetrahydroxymethylammonium phosphate, is a flame retardant in the textile industry and is widely distributed. Its waste treatment is the first priority for safety, especially environmental protection as the core, and should not be hasty. Because THPC is toxic to a certain extent, it has an impact on the environment and life. If it is not disposed of properly, there will be endless problems in the future. The methods for proper disposal are as follows:
Initially, the residual liquid and related wastewater should be stored in a special container, and should not be spilled on the soil and water bodies. It must be sealed and stored, marked with the name and hazards, and other chemicals should not be mixed. The classification of its dirt should follow the corresponding national regulations and cannot be placed with general waste.
The second is to entrust a qualified hazardous waste disposal agency in accordance with regulations and handle it professionally. Commonly used methods are chemical oxidation, neutralization and post-treatment, which are decomposed and converted by chemical reaction to precipitate harmless products. If a strong oxidant is used, slowly put it into the waste liquid containing THPC to adjust the reaction temperature and stir evenly to promote the complete transformation of harmful components. The neutralization reaction also needs to control the pH, remove the residual acidic or alkaline components, and ensure that the waste liquid meets the safe discharge standard.
After wastewater treatment, it is still necessary to monitor the phosphorus content and organic residues. If it exceeds the standard, it should be adsorbed by activated carbon, biological treatment and other processes before discharge. Its solid residue should not be buried at will, and must be incinerated or sent to a designated hazardous landfill for compliant disposal to prevent secondary pollution.
Operators, etc., when wearing protective equipment, strictly prevent contact with the skin and respiratory system. After treatment, the equipment and storage area should be thoroughly cleaned, and the stains should be cleaned with a special detergent to ensure that no traces of traces and toxins remain. Empty barrels of residual liquid also need to be cleaned up and standardized, and managed according to hazardous waste.
All in all, THPC is discarded, not only for pollution control, but especially cautious. Follow regular channels and turn harm into nothing. It is a long-term policy that is in line with the code. In this way, people can be safe and the earth can be kept worry-free.
