Ultrafiltration membranes are super popular for separating different substances. You can find them in areas like oil processing, textiles, biopharmaceuticals, food production, wastewater treatment, and even making drinking water. Scientists are exploring ways to enhance these membranes so they can produce more water without compromising their filtering ability and also reduce pollution. To this end, many scholars are committed to developing new membrane materials and modifying membranes to improve their application effects. There are many methods to modify membrane materials, such as copolymerization, mixing and surface modification. Blending is simple and easy, making it a popular topic in membrane research. That's why many scientists in the field pay attention to it.   Polyvinyl alcohol (PVA 088-08 & PVA 1088)  has good film-forming properties and pollution resistance, and is widely used as a material for preparing hydrophilic membranes.PVA membranes have a tendency to swell and can even dissolve, so they often need some changes, like heat treatment or blending.    To make these membranes, we used materials like polyvinyl alcohol (PVA), cellulose acetate (CA), glacial acetic acid, metal chlorides, and water. We created blended ultrafiltration membranes using a method called phase inversion, adding metal chlorides like sodium chloride (NaCl), potassium chloride (KCl), and barium chloride (BaCl). We checked how the amount of these metal chlorides impacted the performance of the blended membranes.   Our results showed that when the mass fraction of NaCl and KCl doesn't go over 1% in the membrane solution, the modified blended membrane performs well in retaining substances. The pure water flow increases, while energy use stays pretty much the same. But, when the mass fraction goes above 1.5%, the water flow jumps significantly, but the retention rate drops. We found that about 1% is the best amount for the alkali metal chlorides, while for BaCl, around 1.5% works best. Under the same conditions, blending with KCl results in the highest water flow rate. After we changed the PVA-CA blended membrane with NaCl and KCl, it became more water-loving. But when we used BaCl, it got a bit less water-loving.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com  

Polyvinyl Alcohol (PVA) adhesive is a versatile and widely used product in industries. Its unique properties make it an excellent choice for applications such as paints and coatings, paper making, textiles, and more.   PVA (PVA 088-07 & PVA 0888) adhesive has gained popularity in the paints and coatings industry due to its exceptional bonding properties. It provides strong adhesion to various surfaces, including wood, metal, and plastics, making it ideal for both interior and exterior applications. PVA adhesive offers excellent water resistance, flexibility, and durability, ensuring long-lasting results. Its ease of use and low odor make it a preferred choice for professional painters and DIY enthusiasts alike.   The paper making industry relies heavily on PVA adhesive for its superior binding capabilities. PVA adhesive enables the production of high-quality paper products by providing excellent adhesion between fibers. It improves paper strength, enhances printability, and reduces paper breakage during processing. Additionally, PVA offers good water solubility, which is essential for the controlled dissolution of paper in recycling processes.   In the textile industry, PVA adhesive plays a vital role in various applications, such as fabric finishing, laminating, and bonding. PVA adhesive provides a strong bond between different types of fabrics, ensuring secure seams and preventing fraying. It enhances the fabric's overall stability and durability, making it suitable for applications requiring resistance to washing, dry cleaning, and repetitive mechanical stress.   As a water-soluble polymer, PVA offers numerous advantages over other types of adhesives. Its water solubility allows for easy cleanup, reducing the need for harsh chemicals during application and removal. PVA adhesive can be easily diluted to achieve desired viscosity, making it suitable for a wide range of applications. Its non-toxic nature and low environmental impact further contribute to its appeal as a sustainable adhesive option. Polyvinyl Alcohol adhesive stands out as a reliable and versatile choice across various industries. Its exceptional bonding properties, water resistance, flexibility, and ease of use make it a preferred adhesive for paints and coatings, paper making, textiles, and more. Whether it's enhancing the quality of paper products, improving the durability of textiles, or providing a reliable bond in various applications, It continues to be an indispensable tool for industry professionals. Consider incorporating PVA adhesive into your manufacturing processes to benefit from its numerous advantages.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

PVA film, also known as polyvinyl alcohol film, is a remarkable polymer-based packaging material that offers a multitude of advantages for various industries.PVA film is non-toxic and safe for direct contact with food and pharmaceutical products. It meets regulatory standards for food contact materials and does not compromise the quality or safety of the packaged items. PVA film is also used in specialized industrial applications, such as the packaging of adhesives, dyes, and chemicals, thanks to its excellent moisture resistance and barrier properties.   One of the notable variants of PVA film is the PVA water-soluble film. This film is specially designed to dissolve quickly and completely in water, making it an ideal choice for single-use packaging applications. The PVA water-soluble film provides exceptional convenience and eco-friendliness, especially in industries such as food packaging, detergent packaging, and agricultural applications.   In contrast to the water-soluble grade, PVA insoluble film offers excellent resistance to moisture and provides a robust barrier to protect the packaged contents. This type of film is commonly utilized in applications where moisture resistance is critical, such as electronic components packaging, chemical packaging, and industrial materials packaging.   PVA special film refers to the customized versions of PVA film that are tailored to meet specific requirements of different industries. These films may possess additional functionalities, such as enhanced strength, increased clarity, improved tear resistance, or specific barrier properties. PVA special films find applications in diverse sectors like pharmaceutical packaging, cosmetic packaging, and Marble demoulding industrial applications.   PVA (PVA 098-08 & PVA 1099) film can be manufactured in different thicknesses and sizes to suit various packaging needs. Its compatibility with different substances allows it to be used with a wide range of products, including powders, liquids, and solid items. ElephChem can customize PVA film of various sizes and specifications according to customer requirements, suitable for a variety of products.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com
