What are the unique uses of Trisodium Phosphate Anhydrous TSP-A in industrial production and cleaning?
Trisodium Phosphate Anhydrous TSP-A is a capable person in the field of industry and cleaning. In industrial production, in the water treatment process, it can closely combine with hard water ions such as calcium and magnesium in the water, just like a magnet attracting iron, to form precipitation, effectively reduce the hardness of water, prevent scaling of pipes and equipment, ensure smooth circulation of industrial water, and maintain the normal operation of production equipment. When treating metal surfaces, TSP-A can remove oil and rust on the metal surface. Due to its strong alkalinity, it can decompose the molecular structure of oils and fats, making the metal surface clean as new, laying a good foundation for subsequent electroplating, coating and other processes. In the cleaning industry, whether it is cleaning ceramics and glassware, or removing stubborn oil stains in the kitchen, TSP-A can quickly play a role, decompose dirt, and restore the smooth appearance of objects. It is widely used in scenes such as machinery manufacturing and kitchenware cleaning.
What should be done when using Trisodium Phosphate Anhydrous TSP-A?
What should be done when using Trisodium Phosphate Anhydrous TSP-A?
When using Trisodium Phosphate Anhydrous TSP-A, it is necessary to operate it carefully according to different uses. When treating water, first test the water hardness and calculate the amount of TSP-A accordingly. Generally, for every ton of hard water treated, the amount is about 5-15 kg. After preparing it into a solution, slowly add it to the water to be treated, stir it thoroughly to allow TSP-A to fully react with calcium and magnesium ions, then let it stand and settle, and filter to remove impurities. For metal surface treatment, prepare a 10%-20% concentration solution, apply the solution to the metal surface with a brush or spray gun, let it stand for a few minutes, and rinse it with clean water after the oil and rust are loosened. Wear protective equipment such as gloves and masks during operation to prevent skin and respiratory tract irritation.
What are the effects of long-term contact with Trisodium Phosphate Anhydrous TSP-A on human health?
Long-term contact with Trisodium Phosphate Anhydrous TSP-A, if not properly protected, will cause considerable harm to human health. TSP-A is highly alkaline. If it comes into direct contact with the skin, it will quickly corrode the surface of the skin, causing redness, swelling, and pain. If the contact time is long, it may even cause burns. If it accidentally enters the eyes, it will cause serious damage to the eye tissue, causing pain, tears, and blurred vision. If not treated in time, it may affect vision. If its dust is inhaled into the respiratory tract, it will irritate the respiratory mucosa, causing symptoms such as coughing and asthma. Long-term and large-scale inhalation may cause damage to lung function. If TSP-A is ingested by mistake, it will corrode the gastrointestinal tract, causing symptoms such as nausea, vomiting, and abdominal pain, which can be life-threatening in severe cases. Therefore, when contacting TSP-A, you must wear complete protective equipment and keep the workplace well ventilated. If you accidentally come into contact with it, rinse immediately with plenty of water and seek medical treatment as soon as possible.
How should Trisodium Phosphate Anhydrous TSP-A be properly stored?
Storing Trisodium Phosphate Anhydrous TSP-A requires careful adherence to the rules to ensure its quality. This substance prefers dryness and avoids moisture, so the first thing to do is to choose a dry, ventilated and cool warehouse. If it is a treasure, find a dry and secluded room to avoid moisture. The floor of the warehouse must be raised to prevent the invasion of ground air, and the temperature and humidity should be constant. If necessary, dehumidifiers and thermostats should be installed to make the environment suitable.
Packaging is also key. Containers with good sealing performance are often used, such as special plastic barrels or thick woven bags, lined with moisture-proof films, and tightly sealed to prevent external moisture from entering. It is like a strong armor and a high wall. When storing, it should not be mixed with acids, flammable, explosive and toxic substances. Because it is alkaline, it will react violently when it encounters acid. If it is placed with other dangerous substances, it may also cause unexpected disasters.
Regular inspections are required to check whether the packaging is damaged, whether the material is agglomerated or deliquesced. If the packaging is damaged, replace it immediately; if there is any abnormality, deal with it in time. Only by taking such careful care can Trisodium Phosphate Anhydrous TSP-A be stored for a long time without deterioration, and its efficacy will remain the same when it is ready for use.
What will happen when Trisodium Phosphate Anhydrous TSP-A is mixed with other chemicals?
When Trisodium Phosphate Anhydrous TSP-A is mixed with other chemicals, its situation is changeable and must be observed. Because its aqueous solution is alkaline, if it meets with acidic substances, it will be like boiling oil with a raging fire, and it will be violently neutralized, releasing a large amount of heat instantly, or causing the solution to splash, and even causing the risk of explosion. For example, when mixed with hydrochloric acid and sulfuric acid, the reaction is rapid, not only losing its original properties, but also endangering the safety of the surrounding area.
When mixed with some metal salts, changes will also occur. It can react with copper salts, iron salts, etc. to generate corresponding metal phosphate precipitation, the system becomes turbid, and the properties are also changed. If mixed with strong oxidants, although there is no violent reaction, the chemical activities of the two affect each other, or make TSP-A ineffective, or change the properties of the oxidant.
In addition, when mixed with organic substances such as surfactants, the solubility and activity of the organic substances may change due to changes in pH value, making the mixed system unstable. Therefore, before mixing, it is necessary to carefully check the properties of each chemical, or conduct a small test first to explore whether they are compatible. Do not act rashly to avoid causing trouble and endangering production and personal safety.
