2209 Urea-Formaldehyde Resin Powder

ureaformaldehyde resin power2209 Aquatic Feed Adhesive Material Introduction UF-2209 Aquatic Feed Adhesive Material is a new generation product of China. It is a multi-methyl urea polymer. It is a kind of white homogeneous fine powder which can be adhesive when added with water in ambient temperatures. However, it gives full play to its strong adhesive effect after quenching, tempering, and granulation. During quenching and tempering, the moisture brought by the steam causes the rubber powder to fully penetrate the feed fine powder. Under high temperature of quenching, tempering and granulation, polymer produces a chemical reaction. Its molecules themselves produce crosslink. In addition, cellulose, lignin and other substances, which are not easy to digest or absorb in feed materials, also produce covalent crosslink with either link. After cooling and solidification, the polymer forms highly-branched lattice structure. Accordingly, one can gain high-degree water-resistant pellet feed. During the processing of aquatic pellet feed, it can reduce the powder yield rate of granulation and greatly increase the formation rate of pellet feed. It has fine compatibility performance, without any non-compatibility, or impact to trace elements, vitamins or other materials. The specific adhesion of adhesive materials itself allows the pellet feed to have fine water-resistance, reducing the pollution of feed to water quality. Therefore, fish and shrimp diseases are reduced and the stocks' survival rate becomes higher. With high economic benefits, it conforms to national health standards and has no harm or adverse effects on fish or shrimp. In addition, it allows for medium and small feed factory in the manufacturing of pellet feed without the grinding, granulation, aging equipment and other technology aspects of large-scale modification of the high input. In general, as UF-2209 production of aquatic feed formulation is superior bonding materials, advanced production technology, product quality and stability, use it safe, economical and easy to use requirements, and thus by the majority of users. Notes For the production of qualified pellets, please note the correct use method. 1. Sufficient time, temperature and moisture Usually, when this powder is at 100°C, the time for crosslink and solidification is about 1 minute. When the temperature of quenching and tempering and granulation is 100°C, the material must be in the quenching and tempering container and granulation for one minute before this powder can fully crosslink and consolidate. Full moisture penetration is also necessary for consolidation. If there is less time for the consolidation of powder material, the penetration will be finer. Otherwise, the penetration will be worse. If the three conditions above are well-controlled, you can add it according to the dosage regulated in the third item - "use method". Feed factories often use 3 lengthened quenching and tempering containers to solve this problem. 2. Stored in a dry, cool place: It is moisture absorbent and quickly becomes knotted losing effect and fluidity. It is usually packed in moisture-proof bags. Bags with remaining powders should be resealed after use.
