What is the shelf life of polyacrylamide?

2025-02-21

The shelf - life of polyacrylamide can vary depending on several factors:

1. Solid polyacrylamide

- Under normal storage conditions (in a dry, cool, and well - ventilated environment, away from direct sunlight and high - temperature sources), solid polyacrylamide powder or granules generally have a shelf - life of about 2 years. If the storage environment is humid, the product may absorb moisture, which can lead to caking and affect its performance. High temperatures can also accelerate the degradation of polyacrylamide, reducing its effective shelf - life.

2. Liquid polyacrylamide

- Liquid polyacrylamide has a relatively shorter shelf - life compared to the solid form. Usually, in a suitable storage environment (room temperature, protected from light), the shelf - life of liquid polyacrylamide is about 6 months. Liquid products are more prone to microbial contamination, especially in warm and humid conditions. Microbial growth can cause changes in the viscosity and chemical properties of polyacrylamide, reducing its effectiveness for applications such as water treatment or oil recovery.

It is not recommended to use polyacrylamide after it expires for the following reasons:

Deterioration of flocculation effect: During storage, the molecular chain of polyacrylamide will gradually break and degrade. As time goes by, the molecular weight decreases, which will seriously affect its flocculation performance in water treatment or other applications, resulting in the inability to effectively adsorb and bridge impurity particles, making it difficult for the treated water quality to meet the expected standards.
Changes in solubility properties: Expired polyacrylamide may be difficult to dissolve, or the solution may agglomerate and become turbid after dissolution, and it is impossible to form a uniform and stable solution. This will not only affect normal addition and use, but may also clog pipes and equipment, affecting the smooth progress of the production process.
Generation of harmful substances: When stored for a long time and under poor storage conditions, polyacrylamide may undergo chemical changes and generate some substances that are harmful to the environment or subsequent use. For example, in drinking water treatment, if expired products are used, these harmful substances may enter the drinking water and pose a potential threat to human health.

Domestic VS. Imported Carbon Fiber What's the Real Difference in Performance?

2025-02-21

In the ever-evolving field of materials science, carbon fiber has become a cornerstone in many high-end sectors due to its exceptional performance. From high-precision aerospace equipment to lightweight innovations in automotive manufacturing, and even performance enhancements in sports equipment, carbon fiber is everywhere. In recent years, the domestic carbon fiber industry has made remarkable strides and achieved significant accomplishments. However, compared to imported carbon fiber, there are still some performance gaps that cannot be ignored. Today, let’s delve into the differences between the two.

1. Carbon Fiber Performance Indicators

The performance of carbon fiber is mainly measured by several key indicators, which act like its “ID card” and determine its suitability for various applications.

- Tensile Strength: This refers to the maximum load capacity of the material when subjected to tension, much like the heaviest weight a strongman can lift. For example, in the aerospace field, aircraft wings need to withstand tremendous aerodynamic forces during flight. High tensile strength carbon fiber ensures that the wings don’t break under complex stress, ensuring flight safety. For instance, in the manufacture of high-performance fighter jets, there are stringent requirements for the tensile strength of carbon fiber in the wings.

- Tensile Modulus: This reflects the rigidity of the material, similar to how one would measure the stiffness of a spring. In automotive manufacturing, a higher tensile modulus makes the car’s structure more stable, improving vehicle handling and crash safety. When a car takes a sharp turn at high speeds, carbon fiber body components with high tensile modulus can minimize deformation and maintain stability.

- Density: This directly affects the lightweight nature of the product, which is crucial in fields focused on energy efficiency and speed. In the electric vehicle industry, reducing the body weight can significantly improve the range. Using low-density carbon fiber materials for the car body can reduce weight without compromising performance, thereby reducing energy consumption.

- Elongation at Break: This indicates how much the material can deform before breaking, much like how far an elastic band can stretch. In sports equipment such as tennis rackets, an appropriate elongation at break allows the racket to flex slightly upon impact, enhancing hitting power and feel.

These indicators are interrelated but each plays a unique role, contributing to the overall performance of carbon fiber in real-world applications. Together, they determine how carbon fiber performs in different scenarios.

2. Comparison of Performance Parameters: Domestic vs. Imported Carbon Fiber

According to publicly available data, in the high-end carbon fiber sector, imported carbon fibers still maintain a leading edge in tensile strength and tensile modulus due to the long-standing technological advantages they have accumulated. Toray, a global leader in the carbon fiber industry, produces some models of carbon fiber with outstanding performance. The tensile strength of these fibers can exceed 7000 MPa, and the tensile modulus is over 300 GPa. This data indicates that these carbon fiber materials can withstand enormous tension without breaking and possess extremely high rigidity.

Domestic high-end carbon fiber products have made significant breakthroughs in recent years, achieving remarkable progress. However, on average, their tensile strength ranges between 6000 and 6500 MPa, and the tensile modulus falls between 280 and 300 GPa. While there is still a certain gap compared to imported products, domestic carbon fibers continue to make strides, with ongoing increases in R&D investment and gradual improvements in technology.

In the mid-to-low-end sectors, domestic carbon fiber has shown strong competitiveness. Its performance is sufficient to meet most conventional application needs, such as in general industrial products and sports equipment. Furthermore, domestic carbon fiber is more cost-effective, which allows many small and medium-sized enterprises to adopt carbon fiber materials at a lower cost, thus promoting the wider application of carbon fiber across various industries.

3. Performance Differences in Practical Applications

In the aerospace industry, where material performance requirements are almost rigorous, imported carbon fiber has long held a dominant position due to its stable and exceptional performance. Critical structural components like airplane wings and fuselages benefit from using imported carbon fiber to ensure both the safety and fuel efficiency of the aircraft. Taking renowned international aircraft manufacturers such as Boeing and Airbus as examples, they extensively use high-end imported carbon fiber materials in their aircraft production. These airplanes must operate in various complex meteorological conditions and flight states, which demands extremely high reliability and stability from the materials. Imported carbon fiber is able to meet these stringent requirements.

However, in the sports equipment sector, domestic carbon fiber has already found widespread application. In bicycle manufacturing, domestic carbon fiber bicycles have gained popularity among cycling enthusiasts due to their higher cost-effectiveness. While they may slightly lag behind imported products in terms of performance, domestic carbon fiber bicycles have achieved a good balance in terms of lightweight, rigidity, and comfort through optimized design and manufacturing processes.

In the manufacture of fishing rods, domestic carbon fiber rods also perform excellently. Their excellent toughness and strength allow them to meet the needs of fishing enthusiasts across various water environments and fishing scenarios.

Production Process of Polyvinyl Butyral Resin

2025-02-14

The full name of PVB is polyvinyl butyral, or PVB resin for short. It contains a lot of hydroxyl (OH) groups, which can produce bridging reactions with some thermosetting resins to improve chemical resistance and coating film hardness. PVB molecules contain long branched chains and have good flexibility, excellent transparency, strong adhesion, good light resistance, heat resistance, cold resistance, water resistance, film-forming properties, solubility, miscibility, high tensile strength and impact resistance, etc. It is widely used in the fields of manufacturing laminated safety glass, coatings, adhesives, ceramic film decals, vacuum aluminum foil paper, electrical materials, fiberglass products, fabric treatment agents and engineering plastics. It is a synthetic resin material with broad development and utilization prospects.

There are three main synthesis methods for producing PVB in the industry: one-step method, dissolution method and precipitation method. The following will introduce these three process methods and their advantages and disadvantages in the production process one by one.

The one-step method refers to a generation process in which the hydrolysis of polyvinyl acetate (PVAC) and the acetal reaction of the generated PVB are carried out simultaneously. It is represented by the production process of Solutia Company (the chemical division of Monsanto Company was split to form Solutia Company, which has now been acquired by Eastman Company). Vinyl acetate is bulk polymerized to form a methanol solution of polyvinyl acetate, and HCI is added for alcoholysis. The PVA generated by alcoholysis is suspended in a mixed solvent of ethanol and ethyl acetate, and butyraldehyde and HCI are added for acetal reaction. At the reflux temperature, react for 8 to 10 hours. As the reaction proceeds, PVA is completely dissolved and a uniform PVB solution is finally formed. Then add alkali to adjust the pH to 6. After reaching the specified acetal rate, it precipitates in water. After washing, neutralizing and drying, the finished PVB product can be obtained.

The dissolution method is to make PVA into a methanol suspension, add HCI and butyraldehyde to perform a condensation reaction. As the reaction proceeds, PVA gradually dissolves to form a uniform solution. After reaching the specified acetal ratio, it precipitates in water. After washing, neutralizing and drying, the finished PVB product can be obtained. The acetal rate of the PVB resin produced by this method can reach more than 86%, and the condensation distribution is uniform.

The precipitation method requires first dissolving PVA in water (85-90°C), then filtering the solution, pressing it into an acetal kettle, adding hydrochloric acid and butyraldehyde, and adding butyraldehyde in two batches to start homogeneous condensation. When the reaction reaches a certain level, PVB particles are precipitated from the solution and suspended in the mother liquor, which is a heterogeneous condensation reaction. When the condensation is completed, the material is put into a water washing kettle, washed with water, and alkali is added for stabilization, then filtered and dried to obtain powdered PVB.

Various Applications of Polyvinyl Butyral

2025-02-14

Polyvinyl Butyral (PVB) is a versatile and widely-used thermoplastic resin known for its exceptional properties. It is made by the condensation polymerization of polyvinyl alcohol (PVA) with butyraldehyde. PVB offers unique advantages such as transparency, excellent adhesion, impact resistance, and UV stability, making it indispensable in numerous industries.

One of the key characteristics of PVB is its high transparency. PVB films have excellent optical clarity, allowing light to pass through without distortion. This property makes PVB a popular choice for safety glass applications, such as laminated glass used in automotive windshields and architectural windows. The inherent toughness of PVB also enhances the safety of laminated glass by preventing it from shattering upon impact.

PVB exhibits remarkable adhesion to various substrates, including glass, metals, and plastics. This adhesive property makes it an ideal interlayer material for laminated safety glass. The strong bond created by PVB interlayers holds the glass together even when it breaks, thus providing enhanced protection against personal injury and property damage. The adhesion of PVB also makes it suitable for laminating other materials, such as textiles, metals, and electronic components.

When used as an interlayer in laminated glass, PVB significantly improves impact resistance. The tough and flexible nature of PVB helps absorb and distribute energy upon impact, minimizing the risk of breakage. This impact-resistant property finds applications in safety glass for automotive windshields, architectural structures, and bullet-resistant glass.

PVB exhibits excellent resistance to ultraviolet (UV) radiation. It acts as a UV stabilizer, protecting the underlying materials from degradation caused by prolonged exposure to sunlight. This makes PVB an ideal choice for outdoor applications, such as solar panels and architectural glazing, where UV resistance is crucial.

PVB can be customized and modified to suit specific application requirements. By altering the molecular weight and modifying the plasticizers, various grades of PVB with different characteristics can be produced. This versatility enables manufacturers to tailor PVB properties such as viscosity, glass transition temperature, and adhesion strength to meet the specific needs of different industries, including automotive, construction, and electronics.
