At present, the mainstream material of domestic RV housing is still glass fiber reinforced plastic, which is a kind of sheet with very mature production technology. However, glass fiber reinforced plastic also has many outstanding problems, such as poor long-term temperature resistance, fast aging, low elastic modulus, etc. Today we will introduce A new type of composite material sheet, its characteristics are very suitable for the shell of RV, it has the characteristics of strong weather resistance, waterproof, corrosion resistance, aging resistance, lightweight, and strong impact resistance.

Aluminum honeycomb composite material (also known as aluminum honeycomb core, aluminum honeycomb panel) is a composite material that uses multi-layer aluminum foil and high-strength adhesive, and is laminated and stretched into a regular regular hexagonal honeycomb structure. It is mainly used in civil construction, vehicle and ship decoration and aerospace materials.

The full name of refrigerated trucks is refrigerated and insulated trucks, and they have truck bodies with refrigerated and insulated functions. Refrigerated trucks have clear classification standards in the industry. According to the types of transported goods, they are divided into six grades: A, B, C, D, E, and F. Let's take a look at how to distinguish different grades of refrigerated truck bodies, and how to choose a refrigerated truck body that suits your needs.

Thermoplastic polypropylene (PP) honeycomb panel is a new type of environmentally friendly panel made of two thinner panels and PP honeycomb core through hot-melt bonding, with light weight, high strength, 100% recyclable, low thermal conductivity and shock resistance and many other advantages. Due to its excellent characteristics, it has been widely used in the aerospace industry, shipbuilding, commercial transport vehicles, truck bodies, buses, trains, subways and rail transit vehicles in recent years. Now, decoration and home furnishing industries with strict environmental protection requirements have also begun to use non-toxic, odorless and healthy honeycomb panels.

Honeycomb panel is imitating honeycomb structure. The honeycomb structure can produce very light products with less material, so that the weight of the panel can be greatly reduced, and the enterprise can also save costs. The raw materials of honeycomb panels are also different, mainly like paper honeycomb panels, aluminum honeycomb panels, plastic honeycomb panels, etc. Paper honeycombs are mostly used for express delivery and packaging of lightweight items, while aluminum honeycombs are used in occasions that require high performance and are not cost-sensitive.

Chongqing Van-research dry freight truck bodies make great use of new materials and technologies. The panels of the truck bodies are made of thermoplastic fiberglass reinforced polypropylene panels, and the frames, chassis are made of high-strength aluminum profiles. The body panels we use are formed by hot pressing, and the overall structure has high strength and good sealing performance. Compared with traditional iron-clad truck bodies, Chongqing Van-research dry freight truck bodies are lighter in weight, have more payload and lower transportation costs.

With the rapid development of new energy vehicles in recent years, the issue of weight reduction has received widespread attention at home and abroad. At present, domestic passenger cars have some problems in terms of weight, heat insulation and fire resistance. If these problems can be successfully solved, the maintenance cost and energy consumption of passenger cars will be reduced.

The insulated truck body is the main component of the refrigerated truck, and its performance directly determines the special performance of the refrigerated truck. The structure of a refrigerated truck body usually has:

1. The overall skeleton type rigid polyethylene foam board filling structure;

2. The overall skeleton polyurethane foaming structure;

3. Large-plate splicing hard polyurethane injection foaming structure;

4. Insulated car body combined with an open "sandwich" board;

5. Insulated car body bonded with fully enclosed polyurethane panels.
