What are the main uses of polyaluminium chloride (PAC)?
Polysilicate zinc (PAC) has a wide range of uses and is effective in various fields.
In the purification of water, PAC can be called a sharp weapon. Water pollution is also mixed with sundries, dust, and colloids. If you want to get clear water, you must perform purification techniques. When PAC enters water, it can quickly gather particles scattered in the water, causing them to condense into large particles and settle. Such as river water, carrying sediment and humus, it is introduced into a water purification plant and injected with PAC. After a while, the particles merge and sink at the bottom of the pool, and the water on the upper layer gradually clears. This is its contribution to the water purification industry, so that the people can enjoy clean water.
In the papermaking industry, PAC is also indispensable. When making paper, there are many impurities in the pulp, and the distribution of fibers is uneven, which makes it difficult to achieve high quality paper products. Using PAC can help the fibers gather, optimize the distribution, and improve the uniformity and strength of paper products. For example, in ancient papermaking, although craftsmen have a wonderful method, the control of fibers is ultimately not as effective as PAC, so today's papermaking industry relies on it to make exquisite paper products.
Furthermore, in the printing and dyeing industry, the printing and dyeing wastewater is dark and contains various chemicals. If it is discharged directly, it will pollute the environment. PAC can make the dyes and additives in the wastewater coagulate and settle, achieving the purpose of purification. In the past, printing and dyeing wastewater was poorly disposed of, causing rivers to change color. Now with the help of PAC, the wastewater is purified and returned to nature without harming the ecology.
It is also useful in mining. After ore sorting, the water of tailings contains many metal ions and suspended solids. PAC can purify the tailings water and recycle it for reuse, which not only saves water resources but also reduces environmental pollution.
All these things are used for polysilicate zinc (PAC), which is of great service to today's industry and people's livelihood.
What are the advantages of polyaluminium chloride (PAC) compared to other water purifiers?
Compared with other water purifiers, polysulfone amide (PAC) has three advantages.
First, the flocculation efficiency is outstanding. PAC can be quickly dissolved and efficiently hydrolyzed in water, and various polynuclear hydroxyl complex ions can be rapidly produced. These complex ions can strongly compress the electric double layer of colloidal particles, and use the power of electrical neutralization and adsorption to build bridges, so that suspended particles can quickly coagulate and settle. If it is in a water body with high turbidity and mixed pollutants, the speed of flocculation and sedimentation of PAC far exceeds that of other agents, which can quickly clear water quality, take time to shrink and settle, and raise water purification efficiency.
Second, it can adapt to a wide range of water bodies. PAC has good adaptability to water bodies of different water quality and pH value. In acidic to weakly alkaline water bodies (pH about 4-11), it can maintain good flocculation effect. Unlike other agents, it is only suitable for a specific pH range, and the effect is greatly reduced in case of sudden water quality change. PAC can be used in acidic mine wastewater or alkaline industrial wastewater, and is the best choice for water treatment in many scenarios.
Third, it has high safety and little residue. The raw materials used in PAC are mostly common inorganic substances with minimal toxic and side effects. The water treated by it has a small amount of residual aluminum ions. And other water purifiers or harmful substances such as heavy metals, used for a long time, the harmful substances accumulate in the water body, endangering the ecology and human health. PAC is not so dangerous, and it can be used to ensure the safety of water quality, protect the ecological environment and human health.
From this perspective, polysulfone amide (PAC) is superior to other water purifiers in terms of flocculation efficiency, water adaptation and safety, and is actually a good material in the field of water purification.
What is the optimum concentration of polyaluminum chloride (PAC)?
Polysilicate zinc (PAC) is a chemical agent commonly used in many fields such as water treatment. Its optimal concentration is not fixed, and it will vary depending on the specific application scenarios and water quality conditions.
In the context of water treatment, if the turbidity of raw water is low, about 10-50NTU, the concentration of polysilicate zinc (PAC) is usually formulated at 5-10mg/L, which is enough to effectively remove suspended particles and colloidal substances in water and clarify the water quality. If the turbidity of raw water is high, up to 100-500NTU, in order to achieve a good flocculation and precipitation effect, the concentration may need to be increased to 15-30mg/L.
In the field of sewage treatment, due to the more complex composition of sewage, the concentration of pollutants is higher. For general domestic wastewater, the PAC concentration may need to be controlled at 30-50mg/L to effectively remove organic matter, phosphorus and other pollutants. However, if treating industrial wastewater, due to the great difference in water quality, the concentration adjustment range is quite wide, from 50mg/L to hundreds of mg/L.
If treating printing and dyeing wastewater, because it contains a lot of chromaticity and refractory organic matter, the PAC concentration may need to be increased to 200-300mg/L to achieve the purpose of decolorization and removal of some organic matter. When treating electroplating wastewater, in order to remove heavy metal ions, the PAC concentration may be adjusted between 100-500mg/L depending on the concentration of heavy metal ions.
Overall, in order to determine the optimum concentration of polysilicate zinc (PAC), it is necessary to go through laboratory trials and on-site pilot tests, combined with actual water quality characteristics and treatment requirements, to accurately optimize the dosage, which not only ensures the treatment effect, but also avoids the risk of chemical waste and secondary pollution.
What are the precautions for polyaluminum chloride (PAC) during use?
Polysulfone amide (PAC) is a stunner in materials, and many things need to be paid attention to when using it.
The first safety principle. Although this substance has excellent characteristics, safety procedures must be followed when operating. If it is in direct contact, or irritates the skin and eyes, when using it, use it in front of protective equipment, such as gloves, goggles, etc., to prevent inadvertent contact and damage to the body. And under specific conditions, it may have a volatile state. If the emitted gas is inhaled too much, it may harm the respiratory system. It is recommended to ensure smooth ventilation in the workplace, so that the air circulates and prevents the accumulation of harmful gases.
Furthermore, pay attention to the environment. Polysulfone amide is quite sensitive to environmental conditions. If the temperature is too high, it may cause its performance to vary and the strength to decrease. Therefore, the temperature should be controlled within the appropriate range where it is stored and used. And the humidity of the air also affects it. If the humidity is too high, it may absorb moisture, which affects its electrical and mechanical properties. The storage place should be kept dry.
Repeat to understand the suitability. When used in combination with other materials, it is necessary to carefully check their compatibility. Different materials have different chemical properties. If they are not matched properly, or they may react chemically, the properties of the materials will deteriorate. If they come into contact with certain organic solvents, or dissolve or swell, it will seriously affect their performance. Therefore, before use, it is necessary to know whether they can be adapted to the surrounding materials.
In addition, the processing method is also critical. The processing of polysulfone amide requires specific processes and equipment. Parameters such as processing temperature, pressure, and time have a significant impact on its final performance. If the processing temperature is too low, the material fluidity is not good and it is difficult to form; if the temperature is too high, the material may decompose. Improper control of pressure and time can also cause defects such as bubbles and deformation in the molded product. Therefore, during processing, various parameters must be precisely adjusted according to their characteristics.
What are the storage conditions for polyaluminum chloride (PAC)?
Polysulfone amide (PAC) is a special polymer material. Its storage conditions are crucial, related to its quality and stability of performance.
To properly store polysulfone amide, the first dry environment. Because of its certain water absorption, if it is wet, water vapor is easy to invade, causing its molecular structure to change and its performance to be damaged. Therefore, choose a well-ventilated, dry and moisture-free place, such as a warehouse with a constant humidity control below 40%, to ensure that it is not disturbed by water vapor.
The second is temperature control. Polysulfone amide is quite sensitive to temperature, and it is not suitable for too high or too low. Under high temperature, molecular movement intensifies, or degradation, crosslinking and other reactions are caused, which impairs its characteristics; low temperature can cause material embrittlement and greatly reduce flexibility. Therefore, the ideal storage temperature should be maintained between 5 ° C and 35 ° C, so that its performance can be stable and unchanged.
Furthermore, protection from light is also essential. Light, especially ultraviolet light, can cause photochemical reactions, causing the molecular chain of polysulfone amide to break and its performance to deteriorate. Therefore, when storing, avoid direct light, such as using a shading container or a thick curtain in the warehouse to prevent light damage.
When storing, also pay attention to isolation from other chemicals. Polysulfone amides may react with certain chemicals, such as strong acids, strong bases, etc. It must be kept away from such substances, stored in sections, and clearly marked to prevent them from contacting each other and damaging the quality.
In short, in order to store polysulfone amides, it is necessary to have a dry environment, temperature control, protection from light, and isolation. In this way, the material can maintain good performance for a long time, so that it can perform its functions when needed.
