Brief introduction of FRP case:
Glass reinforced plastic automatic water vending machine chassis is my company's latest research and development of a non-metallic materials products. Its product characteristics are light quality, high strength, corrosion protection, insulation, insulation, high temperature resistance, long life and so on. The structure of the product is carefully designed by Professor of mechanics of composite materials at Wuhan University of Technology, and its structural loading fully meets the full load operation of the equipment inside the enclosure. Product form is designed by our company and many customers. Our company will also introduce more models to meet the needs of different customers. In addition, our company can also design, mold and make the products according to the different requirements of customers.
Brief introduction of FRP case and its material characteristics:
Glass fiber reinforced plastic (FRP) is a kind of structural material, which is made of high strength glass fiber and reinforced by unsaturated polyester resin. As a composite material, it combines the advantages of many natural materials. It can produce a wide variety of products according to different processing methods and different materials. Their good properties are listed below:
Strength performance:
Compared with the strength of ordinary steel box, the strength of FRP case is much higher than that of ordinary steel because of its low density. 1.7 times as plain as steel.
Two density:
Conventional glass fiber reinforced plastic density range of 1.6-2.0g/cm3, only steel 1/4 to 1/5, aluminum 2/3, and plastic, wood and other density is equivalent to, is a kind of excellent light, high strength multi-purpose materials.
Three, corrosion resistance
The corrosion resistance of the FRP case and the ordinary steel case is different, as follows: corrosion resistance of FRP
The resin type of the ambient dielectric chassis
Medium concentration% phthalic resin, vinyl resin
25, 52, 25, 52, 25, 52
Sulfuric acid 10, resistance to heat, resistance and resistance
25 resistance, resistance and resistance
50, no resistance, resistance

Hydrogen peroxide 10, resistant, resistant and resistant
Water saturation is Nainai resistance intolerant
Tap water resistance, resistance and resistance
Note: ALL - any concentration.
Four, flame retardant performance
According to the material and use of different kinds of flame retardant, the flame retardant property is divided into the following, with the level of flame retardant: combustion velocity <5 (oxygen index = 65); <10 (oxygen burning rate index = 42); combustion velocity <25 (oxygen index = 32) (industrial grade two grade resistance flame retardant) burning: burning velocity <75 (oxygen index = 28)
Five, aging resistance
High quality matrix resin and anti-aging additive give the durable anti-aging property of glass fiber reinforced plastics, plus its good self-cleaning function, so that FRP can maintain long-term bright luster and lasting high strength. High quality glass fiber reinforced plastic products can last up to 20-50 years.
Six. Electrical performance
As the main raw material of glass steel is used in insulation resin and glass fiber excellent, the glass steel has excellent insulating properties, the breakdown voltage is up to 10KV/mm, the impact is not the spark, is not easy to form the accumulation of static electricity.
Seven. Electromagnetic properties
Glass steel itself is not magnetic, compared to plastic, polyurethane, nylon and other organic materials, its magnetic permeability is the best, so the safe use of anti electric explosion in diamagnetic environment.
Eight, skid resistance
The surface of the glass fiber reinforced plastic can be designed as various antiskid pattern structures or treated by smooth sanding and so on, so as to achieve the antiskid effect of different requirements.
Nine, anti rust, mildew proof
FRP has the advantages of never rusting, moisture-proof and waterproof, so it can be widely used in the atmosphere, water and sewage.
Ten. Cleaning performance
The glass steel surface is covered with resin, it is not easy to clean water advantages, rain water automatic cleaning function.
Eleven, design performance
The characteristics of composite materials endow FRP with various design methods in structure, color, appearance and combination mode, which can meet the special needs of different customers.
Twelve, processability
The lightweight and high strength of FRP makes it possible to cut, polish, drill holes and other conventional processing methods. Different ways of connection such as threading and threading can be achieved through different designs, but FRP can not be welded at present.
