(1) resin usually refers to an organic polymer that has a softening or melting range after heating, tends to flow under the action of external force after softening, and is solid, semi-solid and sometimes liquid at room temperature.
(2) Plexiglass is a kind of transparent polymer material, and its chemical name is polymethyl methacrylate, which is a polymer compound polymerized from methyl methacrylate.
(3) FRP is fiber reinforced plastic, which generally refers to the reinforced plastic with glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin as the matrix and glass fiber or its products as the reinforcing material, and is called FRP or FRP, which is different from tempered glass.
2. Different characteristics
(1) resin has a softening or melting temperature range, which is easy to flow under the action of external force, and often appears as a shell when it breaks. In a broad sense, it refers to polymers or prepolymers used as plastic substrates. Generally insoluble in water, soluble in organic solvents.
(2) Plexiglass can be divided into colorless transparent, colored transparent, pearlescent and embossed plexiglass. Plexiglass has good transparency, chemical stability, mechanical properties and weather resistance, and is easy to dye, process and have beautiful appearance.
(3) FRP includes polyester FRP, epoxy FRP and phenolic FRP. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling and corrosion resistance.
3. Different uses
(1) The main product series of resin environmental protection hot drilling are: resin environmental protection hot drilling, resin, resin hot drilling, Middle East imitation Austrian drilling, imitation Austrian drilling, special-shaped drilling, smooth drilling, water drop, heart-shaped, horse's eye, heart-shaped drilling, circle and so on.
(2) Plexiglass is widely used, not only in commerce, light industry, architecture, chemical industry, etc. In addition, the production of plexiglass is widely used in advertising decoration and sand table models, such as signs, light box panels and Chinese and English letter panels.
(3) FRP is used in cooling towers, FRP doors and windows, building structures, enclosure structures, indoor equipment and decorative parts, FRP flat plates, corrugated tiles, decorative plates, FRP cover plates, surf bathrooms, building construction templates, reinforcing materials and solar energy utilization devices.
Extended data
Advantages of FRP:
1, light weight and high strength.
The relative density is between 1.5~2.0, which is only 1/4~ 1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength is comparable to that of high-grade alloy steel. Outstanding achievements have been made in aviation, rockets, spacecraft, high-pressure vessels and other products that need to reduce their own weight.
2. Corrosion resistance
Glass fiber reinforced plastic is a good corrosion-resistant material, which has good tolerance to air, water, acid, alkali, salt and various oils and solvents.
3. Good electrical performance
It is an excellent insulating material, which is used to make insulators. And can still protect good dielectric property at high frequency. Microwave has good permeability and has been widely used in radome.
4. Good thermal performance
The thermal conductivity of FRP is low, which is1.25 ~1.67kj/(m h k) at room temperature, only11000 ~1000 for metal.
5. Good designability
Can flexibly design various structural products according to needs, meet the use requirements, and make the products have good integrity; Materials can be fully selected to meet the performance of products.
