Control of viscosity modulation of urea formaldehyde resin adhesive by hydrophobic structure molecules
Tech Blog Control of viscosity modulation of urea formaldehyde resin adhesive by hydrophobic structure molecules Urea formaldehyde resin adhesives are the primary adhesives used in the production of engineered wood panels in China and can be applied to bonding units via atomised spraying, roller coating, or immersion coating. The roller coating method is primarily used […]
What are the uses of urea formaldehyde resin?
Tech Blog What are the uses of urea formaldehyde resin? Urea formaldehyde resin is produced by the condensation of urea and formaldehyde in the presence of a catalyst to form urea-formaldehyde resin, which is then converted into a non-melting, non-soluble resin adhesive—urea-formaldehyde adhesive—through the action of a curing agent or additives. It is the most […]
Melamine moulding compound is melamine?
Tech Blog Melamine moulding compound is melamine? Many consumers, and even wholesale buyers, are prone to confusing the two concepts, believing that melamine moulding compound is the same as pure melamine powder. “Is melamine moulding compound the same as melamine?” This question has been asked on more than one occasion. In fact, melamine powder and […]
Urea Formaldehyde Resin Adhesives Modified with Inorganic Additives Study
Tech Blog Urea Formaldehyde Resin Adhesives Modified with Inorganic Additives Wood adhesives play a crucial role in the engineered wood industry, and their development and production standards are essential to ensuring the quality of engineered wood products. Currently, the wood-based panel industry primarily relies on “three aldehyde” adhesives—urea formaldehyde resin, phenol-formaldehyde resin, and melamine-formaldehyde resin—among […]
Transfer of melamine during crop growth
Tech Blog Transfer of melamine during crop growth: impact on crop food safety After the melamine contamination incident sparked global food safety concerns, a key question still remains: can plants absorb melamine from soil or fertilizers and accumulate it in edible parts? The study by the Chinese Academy of Agricultural Sciences tested wheat and corn […]
Melamine and protein
Tech Blog Melamine and protein In 2008, a major food safety crisis shocked the world: tens of thousands of infants in China developed kidney stones, and several died after consuming milk powder mixed with melamine. The core of this tragedy is a simple chemical trick illegally added to food and feed to counterfeit high protein […]
Denitrification and decarbonization of melamine production wastewater
Tech Blog Denitrification and decarbonization of melamine production wastewater As is well known, it is difficult to treat melamine production wastewater, which produces high-concentration wastewater characterized by high ammonia nitrogen content (up to nearly 1000 mg/L) and a low carbon-to-nitrogen ratio. Traditional methods of complete nitrification and denitrification are often difficult to treat such wastewater, […]
Melamine Glucose Resin Adhesive
Tech Blog melamine glucose resin adhesive: a formaldehyde-free wood adhesive Formaldehyde-based adhesives, such as urea formaldehyde resin and melamine formaldehyde resins, dominate the wood panel industry. They provide excellent adhesive strength and water resistance at a low cost. However, formaldehyde emissions have caused serious health and environmental problems. With increasing demand for green buildings, the […]
Water resistance of melamine modified low toxicity urea formaldehyde resin
Tech Blog Water resistance of melamine modified low toxicity urea formaldehyde resin Urea formaldehyde resin is the most widely used adhesive in the artificial board industry, especially for plywood, particleboard, and medium-density fiberboard. They have low cost, fast curing, and good initial adhesion. However, urea formaldehyde resin has two main drawbacks:Poor water resistance-especially to boiling […]
Improvement of the digestion method for melamine concentrated ammonia solution
Tech Blog Improvement of the digestion method for melamine concentrated ammonia solution In the production of urea from CO₂, the stripping process often encounters operational challenges during melamine production. The by-product of melamine production, concentrated ammonia water, often causes bottlenecks in desorption, hydrolysis, steam consumption, and environmental emissions. This article introduces a validated process improvement […]
