FRP and aluminum alloy, which is more suitable for domestic RV
With the further improvement of the performance of chemical products and the continuous improvement of the manufacturing process, non-metallic materials are more and more widely used in the body of domestic RV. They have the advantages of light weight, high strength, corrosion resistance, energy consumption, earthquake resistance, sound insulation, high strength, good manufacturability and easy integration of components. In the 1980s, polyester was widely used in the production of housing cars, and even in the production of housing cars. Local glass toughening of the shell of self-propelled RV in China has been popularized, such as bumper, hood and body parts with large curvature and complex shape. With the continuous development and utilization of raw materials, FRP materials are increasingly used in automobiles.
As we all know, FRP is widely used in the automotive industry because of its advantages such as light weight, high strength, corrosion resistance, energy consumption, earthquake resistance, sound insulation, high strength, good manufacturability and easy integration of components. RV is no exception. It was suggested that what kind of FRP or aluminum alloy is suitable for RV?
FRP and aluminum alloy. In terms of price, aluminum plate is expensive and FRP is cheap, but the strength may be slightly higher than aluminum plate, but FRP has good thermal insulation performance, which is better than aluminum plate, and FRP does not rust, and the internal structure is easy to manufacture, especially complex structure. For the application of RV, FRP is suitable for frequent exposure or extreme cold environment.
Maintenance suggestions for FRP RV shell:
1. Avoid touching sharp and hard objects. In case of friction and collision with other objects during parking or reversing of FRP RV, scratches and other damages will be generated, and protective measures shall be taken.
2. If the shell of domestic RV is found damaged, it shall be repaired in time. Check the car body frequently. If resin peeling, deep scratches and exposed fibers are found, they must be repaired in time, otherwise the damage will be accelerated due to water infiltration.
3. The surface of RV should be kept clean. the surface contaminated with oil and other objects can be cleaned with ordinary household cleaner, not with strong corrosive solvent, decontamination powder and metal wire, so as to avoid leaving scratches and beautiful images. If the stain is difficult to remove, it can be cleaned with gasoline, kerosene, diesel, toluene, xylene, styrene, acetone, etc., but it must be washed with clean water immediately after washing to prevent intrusion into the interior of the structure. When cleaning, it can also be supplemented by a tool scraper, but the hardness should be higher than that of FRP, bamboo, wood or plastic to avoid scratching the surface. When you wash the steel products, you can use soft materials such as Jersey, gauze, soft towels and soft foam plastics. Maintenance suggestions for FRP RV shell:

4. Avoid exposure to the sun in the period. A shed shall be set up at the parking place of the RV. The exposure to the sun in the first half of the year is unfavorable to the FRP, and the color of the gel coat layer will also be affected.
5. Regular wax polishing. In order to make the exterior of Juwei RV bright and protect the gel coat layer, the exterior of Juwei RV shall be polished with wax regularly. The material can be automobile wax or special polishing wax for FRP. It can be two to times, with an interval of 2 each time, so as to form a tough wax film on the surface of FRP. It's best to polish with a portable polishing machine. The surface is as bright as new.
6. Apply paint to maintain beauty and durability. The new RV with gel coat has a beautiful appearance, but after being used for two to five years, the color gradually fades and loses luster, and the dark color is much better than the light color. In order to maintain the beautiful appearance of the RV, when the color of the exterior gel coat layer is old and the scratch is the method of applying oil paint can be adopted. Among all kinds of paints, the surface of the RV should be cleaned first, the wax should be removed with wax remover such as mold cleaning water, and the deep scratch should be embedded with epoxy putty. After doing the preliminary work according to the paint requirements, the paint should be applied (preferably painting). After painting, the RV shell of FRP products factory is as beautiful as the new RV.
