FRP Tank

The proportion of FRP usually to 1.8-2.1, is the steel 1/4-1/5, than steel, casting are and plastic than strength are tall. FRP thermal expansion coefficient of and steel approximately equal, heat conduction coefficient only steel 0.5%.

* FRP vessels, FRP tank chemical corrosion-resistant, long service life: glass fiber reinforced plastic has special decay resistance performance, in the storage corrosive medium, FRP show other materials and incomparable advantages, can resistance to various acid, alkali, salt and organic solvents.

* FRP vessels, FRP tank design flexibility is big, rigid wall structure excellent performance: fiber twines FRP can change resin system or fiberglass reinforced materials to high-speed storage tanks and non-standard equipment of physical and chemical properties, to meet the different needs of medium and working conditions. Through the structural layer thickness, winding angles and wall thickness structure and design to adjust the vessel carrying capacity, made for different pressure levels or some special properties of glass fiber reinforced plastic storage tanks and non-standard device, this is isotropic metal materials and can't compared to.

FRP has the following characteristics: (1) high-strength lightweight, relative density in 1.5 ~ 2.0, only carbon steel between the 1/4 ~ 1/5, but tensile strength is close to that of the carbon steel, and, even more than than intensity can compared with high alloy steel. Therefore, in aviation, rocket, the spacecraft, high pressure containers as well as in other need to lose weight of products of application, have outstanding achievements. Some epoxy FRP tensile, bending and compression strength can be obtained 400Mpa above. Some material the density, strength and than intensity see table 1-1.

(2) corrosion resistant performance is good

FRP is good corrosion resistance materials, to the atmosphere, water and general concentration of acid, alkali, salt and multiple solvent oil and good ability to resist. Already applied to the chemical anticorrosive equipment, various aspects are replacing carbon steel, stainless steel, timber, non-ferrous metals.

(3) electric

Is an excellent insulating materials, used to make insulators. High frequency can still protect good dielectric properties. Microwave through good sex, widely used in radar antenna mask.

(4) thermal performance

FRP thermal conductivity low, at room temperature for 1.25 ~ 1.67 kJ / (m, h, K), only the metal 1/100 ~ 1/1000, is an excellent insulation materials. While instantaneous ultra high temperature conditions, is the ideal thermal protection and antiablative material, it can protect the spacecraft in 2000 ℃ above under high-speed airflow washouts.

(5) can design the gender is good

1 May, according to their needs, flexible design of various structural products to meet the application requirements, can make products have very good integrity.

(2) can fully select materials to meet product performance, such as: can design the corrosion resistance, resistance to high temperature, product one instantaneous direction have special high intensity, dielectric with good sex, etc.

(6) fine workmanship

1 according to the shape of the products can, technical requirements, purpose and the number of flexibility in choose molding process.

2 simple process, can once moldings, economic effect is prominent, especially for complex shape, not easy molding scarce quantity of products, it more prominent handicraft superiority.
