Scope of application
Vinyl ester resin is a modified epoxy resin obtained by the reaction of bisphenol or phenolic epoxy resin with methacrylic acid. It is usually called vinyl ester resin, also known as epoxy acrylic resin, and is thermosetting resin. Anti-corrosion plate, mainly made of unsaturated resin, PVC, fluorocarbon baking paint metal plate, bakelite and other decorative materials.
Anti-corrosion board inherits the excellent characteristics of epoxy resin, and is more excellent in curing and formability. It can be dissolved in styrene and acrylic monomers. Because it has the advantages of both epoxy and unsaturated, it has strong acid and alkali resistance, and its application field is expanding, and is gradually widely adopted by chemical corrosion areas! In highly corrosive areas, the service life can be as long as 25 years.
The anti-corrosion plate is fixed with aluminum profile fasteners, and the corrugated anti-corrosion plate is connected and fixed with anti-corrosion plate bracket and drilling screw, and then sealed with glue. The anti-corrosive plate must be connected with the drill tail screw with a cover plate.
There is no need to overlap the anti-corrosive plate within 12m, and it needs to overlap if it is more than 12m. The overlap length is 200 - 400mm. Two layers of sealant are applied at the overlap. The horizontal overlap does not need to be closed. The overlap of the longitudinal anti-corrosive plate generally does not need to be closed. It is directly fixed with drill screws and applied with sealing glue. The bite plate needs to be closed. The longitudinal overlap of the anti-corrosion plate shall be set near the sandalwood strip.
Performance and characteristics of anti-corrosion plate:
Light weight and high strength: the relative density is 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than carbon steel, and the specific strength can be compared with high-grade alloy steel. Therefore, it has achieved remarkable results in the application of aviation, rockets, spacecraft, high-pressure vessels and other products that need to reduce their own weight. The tensile, bending and compressive strength of some epoxy resins can reach more than 400Mpa.
Good corrosion resistance: It is a good corrosion resistant material, and has good resistance to the atmosphere, water and generally high concentrations of acids, alkalis, salts, as well as various oils and solvents. It has been applied to various aspects of chemical anti-corrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
Good electrical performance: It is an excellent insulating material used to make insulators. It can still protect good dielectric property at high frequency. Microwave transmission is good and has been widely used in radar radomes.
Good thermal performance: low thermal conductivity, 1.25~1.67kJ/(m · h · K) at room temperature, only 1/100~1/1000 of metal, which is an excellent thermal insulation material. It is an ideal thermal protection and ablation resistant material under transient ultra-high temperature.
Good designability: ① Various structural products can be flexibly designed according to needs to meet the use requirements, which can make the product have good integrity. ② Materials can be fully selected to meet the performance of the product, such as those that can be designed to resist corrosion, transient high temperature, have special high strength in a certain direction of the product, and have good dielectric properties, etc.
Good anti-condensation: when the outdoor temperature is 0 ℃, the indoor temperature is 23 ℃, and the indoor relative humidity is lower than 80%, the internal surface of the material will not be dewed.
Excellent processability: ① The molding process can be flexibly selected according to the shape, technical requirements, use and quantity of the product. ② The process is simple, can be formed at one time, and the economic effect is outstanding, especially for the products with complex shape and small quantity that are not easy to form, its process advantages are more prominent.
