Q:Plastic or better glass fiber reinforced plastic better?
Plastic steel and glass fiber reinforced plastic have their own advantages, in the mechanical manufacturing and vehicles, ships and other industrial fields, glass fiber reinforced plastic is used; in furniture decoration, the use of plastic steel profiles.
Q:What does M23 grade of glass fiber reinforced plastic section mean?
There are many kinds of FRP Pultruded Shapes, such as glass fiber reinforced plastic round tube, glass fiber reinforced plastic square tube, glass fiber reinforced plastic rectangular tube, glass fiber reinforced plastic round bar, glass fiber reinforced plastic i-beam.
Q:The difference between polyurethane pultruded profiles and glass reinforced plastic profiles
Compared with other materials, pultrusion with polyurethane can produce a variety of benefits. The utility model can improve the content of the glass fiber in the product and greatly improve the strength of the product. For example, pultruded window frames made of glass fiber and polyurethane resin, the strength of the resulting window frames is 8 times higher than that of the PVC window frames, and the conductivity is 40 times lower than that of aluminum. Therefore, the insulation performance is much better.
Q:Will the FRP section crack for a long time?
It will be。Glass steel cracking has the following factors:1, in production, the ingredients are too high, curing reaction is fierce.2, in production, the product is too thick, no sub operation, resulting in thermal cracking.3, the product stiffness is not enough, deformation is too large and cracks.4, the strength of the product is not enough, the use of excessive force due to cracks.5, surface gel will produce cracks due to thermal contraction.
Q:How to install GRP mark pile
The possibility of theft (because of the pultruded glass steel material is square or triangle pipe is hollow know who stole 1. useless also know this thing is not plastic can not sell 2. take home cushion not after all not solid no component)
Q:What are the circumstances in which the pultrusion should be performed?
(3) the heat deformation temperature of hot deformation temperature high extrusion is 186 DEG C, do not soften at high temperatures, -60 C constant crisp, to ensure the normal use of various environmental temperatures.(4) the water absorption is low, the water absorption of ordinary FRP products is less than 0.5%, while the water absorption rate of pultrusion section is only 0.257%, which is suitable for use in humid environment(5) heat transfer coefficient and low coefficient of thermal insulation rigid PVC pultruded profile approach, made with the single frame double glass insulating window insulation coefficient is only 2.69W/ (M2? K), while the thermal insulation coefficient of the same type of steel, aluminum window made up of 4.0W/ (M2? K). Show that the energy saving glass steel doors and windows is obvious.(6) strong corrosion resistance pultruded profile by 3%HCI solution for 24h, its hardness retention rate was 95%; the 3%NaCl solution for 24h, its hardness retention rate of 89%. so the FRP pultruded profiles for making doors and windows is not only suitable for general residential houses, hotels, restaurants, and more suitable for coastal areas and the corrosive working environment of industrial plant use.(7) to meet the requirements of the environment, the production process of the extruded section has the characteristics of low noise, high efficiency, low power consumption, low pollution, etc., and it conforms to the relevant environmental requirements of the state
Q:Can FRP profiles replace carbon steel profiles?
I am a man of glass fiber reinforced material. Honestly, "I can't do it."". Can be used in buildings, such as insulation, corrosion protection, aging resistance, flame retardant, etc.,
Q:What raw materials do FRP pultrusion require?
Resin: commonly used unsaturated polyester resin, epoxy resin, vinyl ester resin, phenolic resin;
Q:The manufacturing process of FRP products?
1, hand paste production method; 2, spray forming method; 3, fiber winding process; 4, molding process and molding process; 5, pultrusion method.
Q:Are pultruded FRP sections strong? What are its main areas of application?
The tensile strength of products produced by pultrusion process is higher than that of ordinary steel.Widely used in transportation, electrical, electrical, electrical insulation, chemical, mining, marine, watercraft, corrosive environment and life, civil areas.
