VAE Emulsion

Dispersion polymerization is another kind of heterogeneous free radical polymerization of alene monomers except suspension polymerization and emulsion polymerization. Dispersion polymerization can be regarded as a polymerization between suspension polymerization and emulsion polymerization, and its characteristics are as follows: 1) Water or non-water solvent can be used as the medium. When water is used as a medium, the monomer must be insoluble in water or substantially insoluble in water.2) The dispersion of monomers in water is achieved by intense agitation, and the protective colloid added to the system plays a role in preventing the agglomeration of dispersed phases.3) Water-soluble initiators are required for dispersion polymerization with water as the medium.   In form, dispersion polymerization has many similarities with emulsion polymerization. But there are clear differences. Dispersion polymerization, for example, does not use typical emulsifiers but uses protective colloid to stabilize the polymerization system; The particles obtained by polymerization are larger than those obtained by emulsion polymerization. Let's wait.The polymerization of vinyl acetate in water with polyvinyl alcohol as a protective colloid is a typical dispersion polymerization. Vinyl acetate is a water-soluble monomer with a solubility of about 2.5% in water at room temperature and is easily hydrolyzed. The hydrolysis product acetic acid can seriously interfere with the normal process of polymerization. Therefore, the dispersion polymerization of vinyl acetate has more complicated factors than the common emulsion polymerization. It is believed that the dispersion polymerization of vinyl acetate does not occur in micelles, but the monomer dissolved in water is first polymerized, and when the molecular weight reaches a certain level, the polymer precipitates from the water to form latex particles on the protective colloid. In order to improve the stability of the polymerization system and products, an appropriate amount of emulsifier is added in the dispersion polymerization of vinyl acetate, but the role of emulsifier in polymerization is auxiliary.   Attentions： PVA usually has two specifications of 1788 and 1799 (17 indicates a degree of polymerization of 1700, 88 and 99 indicate an alcoholysis degree of 88% and 99%, respectively). When used as a dispersion polymerization protective colloid, it is best to use 1788, and the resulting product has good stability.2. In the polymerization process, the monomer droplet acceleration should be slow and not fast. Generally, a slight reflux in the condenser is appropriate.3. The boiling point of vinyl acetate is between 70-75℃. After adding drops, the heating rate should be slow, too fast and easy to caking.   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.

When VAE is mixed with sand slurry, many properties are improved, but the properties of mortar are also different due to the amount of emulsion mixed in mortar. According to research, from the comprehensive point of view of performance and economy, it is considered that the P/C (polymer weight/cement weight) value is between 0.1 and 0.4.   Increase mortar strength: The fluidity (flow value) of the mortar increases with the increase of the amount of emulsion added, and can rely on mixing with the emulsion to reduce the amount of water, so as to obtain a dense hardened substance, and can increase the strength, so that the shrinkage rate and water absorption decline. Improve the brittleness of mortar: When VAE emulsions are mixed into it, vibration-absorbing polymer particles fill the cement Spaces, thus improving the impact resistance of the mortar. Improve chemical resistance: The mixed VAE emulsion can improve the acid resistance of the mortar and prevent the corrosion of salt water, machine oil, ammonia, methanol and other chemicals.   The use of synthetic resins can improve the strength and adhesion of concrete, mortar, etc: The synthetic resin solution is applied to the surface of the original concrete or mortar, and then the surface is covered with new concrete or mortar, which can eliminate the "rough work" process. At present, polyvinyl acetate emulsions and styrene-butadiene rubber latex are commonly used, and VAE emulsions have greater bond strength than these two emulsions. Pure mortar has no bonding strength for wood, metal, plastic, etc., and only when the polymer is mixed in, the mortar can bond with wood, etc. High strength can be obtained by curing in the air (it is not necessary to spray water onto the poured mortar). If the hydration reaction of cement products is not sufficient, then it cannot get the inherent strength, so if the mortar is cured in the air, then it is brittle and easy to crack. If VAE emulsions are mixed in, the strong hydration force of the emulsions prevents the mortar from losing water too quickly, thus providing the moisture needed for cement curing.   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.

There are two main types of polyvinyl (PVA) based on the degree of hydrolysis, which refers to the extent to which the vinyl acetate monomers in PVA have been converted to vinyl alcohol units.   Fully Hydrolyzed PVA: This type of PVA has undergone complete hydrolysis of the vinyl acetate units, resulting in a high degree of hydrolysis and a high concentration of vinyl alcohol units. Fully hydrolyzed PVA has excellent water solubility and forms strong and stable films after drying. It is widely used as an adhesive, binder, film-forming agent, and thickener in various industries such as papermaking, textiles, packaging, construction, and personal care products.   Partially Hydrolyzed PVA: Partially hydrolyzed PVA has undergone partial hydrolysis of the vinyl acetate units, resulting in a moderate degree of hydrolysis and a lower concentration of vinyl alcohol units compared to fully hydrolyzed PVA. This type of PVA combines the advantages of both PVA and its precursor, polyvinyl acetate (PVAc). Partially hydrolyzed PVA is commonly used as a protective colloid, emulsion stabilizer, and dispersing agent in the production of adhesives, paints, coatings, and textile printing pastes.   Both fully hydrolyzed PVA and partially hydrolyzed PVA have their specific applications and properties, and their usage depends on the desired characteristics and requirements of the end product in various industries.   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

Polyvinyl alcohol (PVA) is generally considered safe and environmentally friendly. It is non-toxic, biodegradable, and does not release harmful substances during use or decomposition. PVA is derived from renewable resources, such as petroleum or natural gas, and it can be produced with minimal environmental impact.   PVA's biodegradability means that it can break down naturally over time, reducing its potential impact on ecosystems. However, its rate of biodegradation depends on various factors such as temperature, humidity, and microbial activity in the environment. In general, PVA is considered to degrade at a moderate rate compared to some other materials.   Polyvinyl alcohol is not considered a microplastic. Microplastics are typically tiny plastic particles measuring less than 5 mm in size and are often created from the breakdown of larger plastic materials or the direct release of small plastic particles. PVA, on the other hand, is a water-soluble synthetic polymer derived from polyvinyl acetate through a hydrolysis process. When PVA is exposed to water or moisture, it dissolves completely, unlike microplastics that persist in the environment.   In summary, PVA is generally considered a safe and climate-friendly material due to its biodegradability, low toxicity, and minimal environmental impact during production. However, as with any material, responsible use and proper disposal practices are essential to ensure its environmental sustainability.   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.
