The resin bond diamond (RBD) is mutil-stalline diamond superhard abrasive specially produced for resin bond abrasives, which is composed of many subcrystals with embedded structure. In most cases, the resin binder system is phenolic resin or polyimide resin. In special cases, special resin binder and suitable additives may be used make the resin bond diamond more widely applicable. Resin bond diamond has irregular crystal shape, rough surface, excellent brittleness and excellent self-sharpening. Characteristics The excellent quality of high grinding efficiency, long life and high finish provides the best performance for resin bond abrasives, the details are as follows: Extremely high grinding efficiency and abrasive utilization : Under a certain grinding force, multicrystal particles are easy to fracture along the interface between subgrains. After the small abrasive subgrains are separated from the crystal particles, the new irregular shape subgrains form sharp edge angles on the cry...

  Related Performance of ETFE ETFE exhibits excellent toughness and wear resistance in a wide temperature range, and it combines high tensile strength, high impact strength, bending resistance and creep resistance, and combines the mechanical properties of hydrocarbon engineering polymers. Performance is combined with the chemical resistance and heat resistance of perfluoropolymers. ETFE has good friction and wear properties, which can be improved by adding fillers (such as glass fiber or bronze powder). Fillers can also improve creep resistance and increase softening temperature. Generally, the continuous upper limit of ETFE operating temperature is 150°C (302°F). When the polymer is crosslinked by peroxide or ionizing radiation, the physical strength can be maintained at a higher temperature. Highly crosslinked resins can withstand temperatures up to 240°C (464°F) in a short period of time. ETFE exhibits excellent dielectric properties, and its dielectric constant is very low, b...

  In the world of polymers, the relentless assault of UV degradation is a perpetual challenge. UV radiation, whether originating from the sun or artificial sources, wreaks havoc on polymers, leading to compromised physical and chemical properties, discoloration, and a host of performance issues. It is in the face of these ever-present threats that light stabilizers  emerge as invaluable allies. Understanding UV Degradation of Polymers l  Weakened Mechanical Properties:  UV degradation precipitates the deterioration of the mechanical properties of polymers, leading to compromised strength, elasticity, and durability. l  Reduced Molecular Weight:  Exposure to UV radiation instigates the disruption of molecular chains within polymers, resulting in a reduction of molecular weight. This phenomenon undermines the structural integrity and performance of the affected polymers. l  Loss of Transparency:  Transparent polymers are particularly susceptible to ...

  What Is Bipolar Membrane Electrodialysis? Bipolar membrane electrodialysis (BMED) is a system that combines electrodialysis (ED) and  bipolar membrane  (BPM), developed for its ability to convert anions and cations into acids and bases, respectively. BMED is composed of BPM,  cation exchange membrane  (CEM) and  anion exchange membrane  (AEM) in a certain arrangement, involving three basic membrane structures: Three-chamber BMED It contains CEM, AEM and BPM in each membrane repeating unit to achieve acid and alkali separation and recovery from salts. Two- chamber base-BMED It contains CEM and BPM in each membrane repeating unit for processing weak acid salts (organic acid salts) to obtain relatively pure bases. Two-chamber acid-BMED It contains AEM and BPM in each membrane repeating unit for converting weak base salts into relatively pure acids. How Bipolar Membrane Electrodialysis Works Under the action of a DC electric field, the bipolar membrane c...
