What is the solvent for EVA?
EVA (ethylene-vinyl acetate) is a copolymer of ethylene and vinyl acetate, which is used in various applications including the production of solar panels. In the production of solar panels, EVA is used as the encapsulating material to protect the sensitive cells from moisture, dust, and other environmental factors. However, during the manufacturing process, excess EVA material is generated which needs to be reclaimed for reuse.
One of the most effective solvents for EVA is ortho-dichlorobenzene (O-DCB). O-DCB is a colorless liquid that is commonly used as a solvent for various polymers and resins due to its high solvency power. It has a relatively low boiling point, which makes it easy to evaporate and reclaim after use. In addition to its high solvency power, O-DCB is also known for its low toxicity and non-flammability, which makes it a safer option compared to other solvents.
O-DCB is used to dissolve the EVA layer completely due to the irradiation. The EVA material is irradiated with ultrasonic waves, which breaks down the polymer chains and cuts them into smaller pieces. Once the polymer is disintegrated, the solvent is added to dissolve it completely. After the EVA material is completely dissolved, it can be separated from the other components and recycled for reuse.
For the recovery and recycling of EVA material, O-DCB is the most effective solvent due to its high solvency power, low toxicity, and non-flammability. By using O-DCB as a solvent, excess EVA material generated during the production of solar panels can be reclaimed and recycled, leading to reduced waste and cost-efficiency.
Are EVA foam fumes toxic?
EVA (ethylene-vinyl acetate) foam is a popular material used in a wide range of applications, such as in flooring, sports equipment, and children’s toys. It’s known for its durability, cushioning, and resistance to water and other chemicals. However, concerns have been raised about the potential toxicity of EVA foam fumes.
EVA foam is usually considered to be a safe alternative to other types of synthetic materials, such as PVC (polyvinyl chloride), because it doesn’t require plasticizers like phthalates, and it’s BPA free. These chemicals have been linked to various health problems, such as hormonal disturbances and developmental issues. Therefore, EVA foam has gained popularity among manufacturers and consumers who are looking for safer materials.
However, a few years ago, it was found that EVA foam contained a chemical called formamide. Formamide is used to make the foam soft and flexible, and it’s commonly found in other materials, such as adhesives and coatings. But it’s also considered to be a carcinogenic and developmental toxin. Inhaling formamide fumes can cause eye, nose, and throat irritations, as well as headaches, dizziness, and nausea. It can also be harmful to the reproductive system, especially in pregnant women.
Although the amount of formamide in EVA foam is usually low, it’s still a cause for concern, especially in products that are used by children or that are in contact with the skin or mucous membranes. The European Union has set a limit of 200mg/kg for formamide in children’s toys, but this limit is not universally enforced. Some manufacturers have taken steps to remove or reduce formamide in their EVA foam products, while others claim that the levels are safe and within legal limits.
To minimize the potential risk of exposure to EVA foam fumes, it’s recommended to use products in well-ventilated areas, and to avoid prolonged exposure to the foam, especially if it’s new or has a strong odor. It’s also advisable to buy products from reputable sources and to look for certifications that guarantee the absence of harmful substances.
Eva foam is generally considered safe, but the presence of formamide in some products raises concerns about its potential toxicity. More research and regulation may be needed to ensure that EVA foam is free of harmful chemicals and suitable for widespread use. If you have concerns about EVA foam products, consult with a healthcare professional or toxicologist.
What are the disadvantages of EVA plastic?
EVA (Ethylene-Vinyl Acetate) is a commonly used plastic material in various industries due to its flexibility, lightweight, and durability. However, like any other material, EVA also has its own shortcomings. Some of the key disadvantages of EVA plastic are its poor tensile strength, low resistance to heat deformation, and poor chemical resistance and barrier properties.
Tensile strength plays a crucial role in determining the durability of a material. Unfortunately, EVA plastic does not possess high tensile strength. The material is prone to tears and punctures, which makes it unsuitable in applications involving heavy usage or rough handling. The material is also susceptible to abrasion and wear, leading to its frequent replacement, which adds to the cost of operations.
Another significant disadvantage of EVA plastic is its low resistance to heat deformation. The material starts to deform at temperatures exceeding 80 degrees Celsius, which limits its use in certain applications that require exposure to high temperatures. This property also makes it unsuitable for outdoor use as exposure to sunlight and other environmental conditions can cause deformation, reducing the lifespan of the material.
In addition to low tensile strength and poor heat resistance, EVA plastic also has poor chemical resistance and barrier properties. EVA plastic is susceptible to certain chemicals, which can cause it to degrade rapidly or swell, leading to its failure. The material is also not an effective barrier against moisture, oxygen, or other foreign particles, which can cause contamination or corrosion in certain applications.
While EVA plastic has many benefits, it also has its own set of disadvantages. Its low tensile strength, poor resistance to heat deformation and chemical resistance and barrier properties make it unsuitable for many applications. These limitations make it essential for businesses to evaluate their application’s requirements before deciding on the use of EVA plastic.
What are the best fabrics that don’t smell?
When it comes to clothing, one of the biggest concerns that people have is the smell that can accumulate over time, especially during the summer season or while working out. Hence, finding fabrics that are both comfortable and don’t retain odor is essential. While there is no straightforward answer to what fabrics don’t smell, there are certain materials that are more breathable, moisture-wicking and bacteria-resistant, making them less likely to retain odors.
One of the best fabrics that don’t smell is cotton. It is one of the most popular fabrics in the world due to its breathability and durability, and is also a natural fiber. It allows sweat to evaporate, inhibits bacterial growth, and is easy to wash. It is best to wear it in dry and moderately hot conditions since cotton can take a longer time to dry than synthetic fabrics.
Linen is another natural fabric that has been known to have antimicrobial properties, which makes it a good choice for warm weather clothing due to its breathability. Similarly, bamboo is a material that is also antibacterial and moisture-wicking, but it also offers many other benefits, such as being extremely soft and hypoallergenic. It has gained popularity in recent years in fitness wear due to its comfort and odor-resistant nature.
In addition to natural fabrics, some synthetic fabrics are also excellent options for odor-free clothing. Polyester is a synthetic material that is moisture-wicking, enabling it to draw sweat away from the skin, which prevents the growth of odor-causing bacteria. Nylon is another synthetic material that is breathable, lightweight and also moisture-wicking, making it ideal for activities such as running and hiking.
Fabrics that don’t smell are dependent on the environment a person is in, the amount of sweat produced, and individual body chemistry. However, some natural and synthetic fabrics such as cotton, linen, bamboo, polyester and nylon are better than others when it comes to odor reduction and are worth considering when looking for comfortable and odor-resistant clothing.
