Introduction of electrostatic spraying equipment
Electrostatic spraying equipment Dusting equipment electrostatic powder coating commonly known as “electrostatic spray”. The spray can be manual, automatic or manual + automatic. 100% of the spray material is a solid powder, the free powders can recycle the paint recycling rate up to 98%. Suspension of the transport system, a high degree of automation. The coated microporous less, good corrosion resistance, and can be a thick film. Electrostatic powder coating based on having an atomizing Tsui (the paint atomizing), andRead More …
Glycidyl Methacrylate GMA- TGIC Replacement Chemistries
Glycidyl Methacrylate GMA- TGIC Replacement Chemistries Acrylic graft copolymers containing free glycidyl groups These hardeners,which include glycidyl methacrylate(GMA) curatives have recently been promoted as crosslinkers for carboxy polyester. Since the cure mechanism is an addition reaction, film builds that exceed 3 mils(75 um) are possible. So far, accelerated weathering tests of polyester GMA combinations indicate results similar to those of TGIC. Some formulating problems exist when acrylic graft copolymers are used ,for example, flow and leveling properties are relatively poor.Read More …
Tetramethoxymethyl glycoluril (TMMGU),TGIC Replacement Chemistries
Tetramethoxymethyl glycoluril (TMMGU), TGIC Replacement Chemistries Hydroxyl polyester/TMMGU combinations,such as powderlink 1174,developed by Cytec, may offer an excellent opportunity to replace TGIC in applications that require thinner film builds. As this chemistry’s cure mechanism is a condensation reaction, some of the application problems described in the section on HAA curatives also occur with this curative. However, recent evaluations and data show that pin hole free coatings can be obtained with hydroxyl polyester / TMMGU combinations even when film builds exceedRead More …
Particle size distribution analsis for powder coating
Particle size distribution analsis for powder coating laser particle size analyzer test results: Average particle size (median diameter), the boundary of particle size and particle size distribution of the dispersion. The average size of the sample is less than and greater than 50% of particles. The boundary particle size: closer to the common sense to the maximum and minimum particle size. However, the maximum and minimum particle size to describe the upper and lower limits of the sample particle sizeRead More …
Electrostatic Spraying Nozzle
Classification of electrostatic spraying nozzle Electrostatic spraying can be divided into the way the air or hydraulic atomizing electrostatic spraying, centrifugal electrostatic spraying, etc.; Electrostatic spraying can be divided into the way the air or hydraulic atomizing electrostatic spraying, centrifugal electrostatic spraying, etc.; direct nozzle electrostatic spraying, electrostatic spray of Y-type nozzle target nozzle electrostatic spraying can be divided according to the different characteristics of the nozzle; in accordance with the paint can be divided into the different nature ofRead More …
Characteristics of electrostatic powder coating spraying
Characteristics of electrostatic powder coating spraying Electrostatic powder coating spraying because he does not use the solvent will not cause solvent pollution in the atmosphere, while avoiding the danger of fire due to the solvent, is also easy to transport and storage of raw materials. The spraying process, the overspray powder is not coated on the workpiece can be recovered, the recovery rate of up to more than 95%, to improve the utilization of raw materials, to reduce the materialRead More …
Characteristics of the electrostatic spraying
Generally speaking, where does not occur at 200 ℃ deformation, enables the charged powder particles are adsorbed on the surface to be painted, the surface coating can be by electrostatic powder spraying. Therefore, electrostatic powder coating spraying technology can be widely used instruments, household appliances, mechanical and electrical equipment, automobile and shipbuilding, light industry equipment, furniture, machinery and building materials, and other metal parts of the surface protection and decorative painting. View from currently used in spray technology, electrostatic powderRead More …
