PVA (Polyvinyl alcohol) is a versatile polymer known for its excellent water solubility. The dissolution of PVA is a crucial step in various applications, such as film production, adhesives, and textile processing. When immersed in water, PVA undergoes the hydration process, forming a gel-like structure. As water molecules penetrate the PVA polymer chains, hydrogen bonding occurs, leading to the separation of polymer chains and subsequent dissolution. Temperature plays a significant role in the PVA dissolution process. Higher temperatures generally accelerate the dissolution rate due to increased molecular motion and higher kinetic energy. However, excessively high temperatures can lead to the degradation of PVA, affecting its performance. It is recommended to maintain the temperature within a suitable range for optimal dissolution without compromising the integrity of the polymer. Elephchem can provide polyvinyl alcohol in different mesh sizes. The particle size of PVA particles also influences the dissolution rate. Finer particles have a larger surface area, allowing for faster water penetration and molecular interaction. In comparison, larger particles have a smaller surface area, resulting in slower dissolution rates. For instance, PVA with 12-mesh, 25-mesh, and 80-mesh particle sizes will exhibit varying dissolution rates, with finer particles dissolving more rapidly. Stirring plays a crucial role in enhancing the PVA dissolution process. When the water and PVA mixture is stirred, it increases the surface contact area between the polymer and the solvent, facilitating faster dissolution. Agitation also helps in preventing the formation of lumps or clumps, ensuring uniform dissolution throughout the solution. Proper stirring techniques and equipment can significantly improve the dissolution efficiency. Apart from temperature, particle size, and stirring, several other factors can affect the PVA dissolution process. These factors include the concentration of PVA in the solution, pH levels, presence of impurities, and the compatibility of additives. It is important to consider these variables and optimize the dissolution conditions accordingly for specific applications. Please refers to "PVA dissolution methods" The dissolution process of PVA is influenced by multiple factors, including temperature, particle size, stirring, and various environmental parameters. Understanding these factors is crucial when working with PVA to achieve desirable dissolution rates and ensure optimal performance in different applications. As an environmentally friendly and water-soluble polymer, PVA offers a wide range of application opportunities, from packaging films to adhesives, textiles, and more. Its versatility and potential for sustainable solutions make it a promising material for various industries worldwide.   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.

VAE emulsion is the abbreviation of vinyl acetate-ethylene copolymer emulsion. It is a polymer emulsion formed by emulsion polymerization of vinyl acetate and ethylene monomer as basic raw materials with other auxiliary materials.‌The production process of VAE emulsion mainly includes the following steps‌: The main raw materials of VAE emulsion include ethylene, vinyl acetate, emulsifier and initiator. Ethylene can be made from naphtha or natural gas; vinyl acetate is made from the reaction of ethylene and acetic acid.   After mixing ethylene and vinyl acetate in a certain proportion, they are passed into the reactor, initiators and emulsifiers are added, and emulsion polymerization is carried out under appropriate temperature and pressure. Control the reaction speed and temperature to completely convert the monomer and generate VAE emulsion‌.   The generated VAE emulsion needs to be degassed to remove unreacted monomers and low molecular volatiles. Adjust the pH value of the emulsion to make it more stable, and perform filtration to remove impurities and solid particles in the emulsion.   Put the processed VAE emulsion into a special container, seal it and store it away from direct sunlight and high temperature environment.   The production and use of VAE emulsion must comply with national and local environmental protection standards, including emission standards for waste water, exhaust gas, noise, etc. Waste water, waste gas and other waste generated during the production process need to be effectively treated and discharged to ensure compliance with environmental protection requirements.   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.

Vinyl acetate is a colorless flammable liquid with a strong odor. Its vapor is irritating to the eyes. It is insoluble in water but soluble in most organic solvents. Vinyl acetate monomer is flammable and reacts rapidly with chlorine, bromine, and ozone. There are two production process routes for vinyl acetate monomer: the ethylene method and the acetylene method. The acetylene method can be divided into a liquid phase method and a gas phase method, and the ethylene method can also be divided into a liquid phase method and a gas phase method.   Acetylene gas phase method: desulfurized and dephosphinated calcium carbide acetylene and acetic acid are used as raw materials, the catalyst is zinc acetate-activated carbon (15:100), and a promoter is added. The reaction temperature is 170~200℃, the pressure is atmospheric pressure, and the space velocity is 200~400/h. Reaction results: acetic acid single-pass conversion rate is 25~40%, acetylene single-pass conversion rate is 12~16%. The selectivity of VAM is 92~96% for acetylene and 95~98% for acetic acid. The total yield of VAM is 97~98% for acetic acid and 92~96% for acetylene.   The catalysts for the ethylene gas phase process are mainly Pd-Au, Pd-Pt and Pd-Cd supported catalysts, and the carriers are mainly silica gel and alumina. The two main factors affecting the catalyst are the coordination ability of Pd and the ability of acetic acid or acetate to oxidize Pd(0) to Pd(II). The single-pass conversion rate of ethylene in this process is 8~10%, the single-pass conversion rate of acetic acid is 8~20%, and the VAM selectivity based on ethylene is 90~94%.   In the past few years, the acetylene process has been gradually replaced by the ethylene process due to the high cost of raw materials. However, with the continuous rise in oil prices, the acetylene process has regained economic vitality, especially the acetylene process using natural gas as raw material. At present, the acetylene process still occupies an important position in China. The ethylene gas phase process occupies a dominant position in the market due to its good processability and economic performance. At present, the ethylene production technology in China accounts for more than 55% of the total national production capacity.   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.
