Amino resins are a type of thermosetting polymers that are formed by combining an aldehyde with an amino compound. They find wide application in various industries due to their unique properties and versatility. In this article, Johnley Factory, the manufacturer of amino plastics production line, will explore the characteristics of amino resins and their significant contributions to the plastics industry. Properties and Benefits The two primary types of amino resins are urea-formaldehyde (U/F) and melamine-formaldehyde. U/F resins dominate the amino resin market, accounting for more than 80% of the production, while melamine-formaldehyde resins make up the remaining segment. Amino resins offer several attractive features, including water solubility before curing, colorlessness, excellent solvent resistance, outstanding hardness and abrasion resistance, as well as good heat resistance.   Applications in Adhesives Amino resins are widely used in the production of adhesives, which represents their largest market segment. These adhesives are essential for various applications such as plywood manufacturing, chipboard production, and construction of sawdust boards. Additionally, different types of aminoins are employed in the production of laminated wood beams, parquet flooring, and furniture assembly. The versatile nature of amino resins makes them an integral part of adhesive formulation and enables the creation of durable and reliable bonding solutions.   Utilization in Thermosetting Plastics Aminoplasts, a type of thermosetting plastics, can be molded using an automatic injection-molding process similar to that used for thermoplastics. This process is particularly suitable for relatively small moldings. The key advantage of injection molding lies in its ability to eliminate manual labor costs, enabling amino resins to compete more effectively with thermoplastics. The future prospects for amino resins and plastics appear promising, with anticipated developments focusing on highly specialized materials for treating textiles, paper, and other industries. Furthermore, amino resins can be combined with other resins to develop advanced formulations for surface coatings.   Manufacturing Process Most amino resins are derived from the reaction between formaldehyde and urea or melamine. The manufacturing process involves two crucial steps. The first step, known as methylolation or hydroxymethylation, introduces the hydroxymethyl group into the molecular structure by adding formaldehyde. The second step involves a condensation reaction, during which monomer units are linked together, resulting in the formation of dimers, polymer chains, or large networks commonly referred to as methylene bridge formation, polymerization, resinification, or cure. Precise control of the reaction course, speed, and extent is critical for successful manufacturing of amino resins. Typically, amino resins are produced through a batch process. Both urea-formaldehyde a...

Turbo mills have emerged as crucial equipment in various industries, including pharmaceuticals, chemicals, and food processing.  In this article, Johnley Factory will delve into the working principle of turbo mills, exploring their intricate mechanisms and highlighting their benefits in achieving finely ground particles. 1. Overview of Turbo Mills Turbo mills, also known as turbo crusher, are high-speed grinding machines designed to break down solid materials into smaller particles. These mills utilize principles of centrifugal force, impact, and shearing to achieve the desired particle size reduction. T 2. Rotor and Stator Configuration At the heart of a turbo mill lies the rotor and stator assembly. The rotor, equipped with multiple blades or pins, revolves at high speeds, generating a powerful vortex and generating centrifugal forces. The stator, comprising an array of stationary pins or grooves, creates a strong shear zone where the particles are subjected to intense grinding forces. 3. Particle Entrapment and Acceleration When the material enters the turbo mill through a feed inlet, it immediately encounters the rapidly rotating blades of the rotor. The blades entrain the particles into the high-speed vortex, where they experience both centrifugal and impact forces. This entrainment and acceleration mechanism ensures that the particles are efficiently and uniformly distributed within the grinding chamber. 4. Grinding and Classifying Zone As the particles circulate within the grinding chamber, they repeatedly collide with the blades, stator pins, and each other. These collisions result in a combination of impact and shear forces, leading to fragmentation and size reduction. The stator pins play a crucial role in intensifying the shear forces by ensuring a narrow gap between the rotor and the stator, creating a controlled turbulence that enhances the grinding efficiency. 5. Particle Size Control One of the key advantages of turbo mills is their ability to achieve precise particle size control. The particle size is primarily regulated by the rotational speed of the rotor, the stator design, and the gap between the rotor and stator. By adjusting these parameters, operators can produce a wide range of particle sizes tailored to specific application requirements. 6. Air Classification In certain applications, turbo mills incorporate an air classification system to further refine the particle size distribution. The classification occurs within the grinding chamber, where a stream of air, introduced through specially designed nozzles, carries the fine particles upward and separates them from the coarser material and finally ensures a high level of uniformity and consistency in the final product. Turbo mills' precise control over particle size, combined with their high throughput capabilities, make turbo mills an indispensable tool for achieving optimal product quality and performance.
