A refrigerated truck is a special vehicle that is used to transport special items. Therefore, the vehicle itself must also select materials suitable for the low temperature itself. The body of a refrigerated truck is made of special materials.
Refrigerator car body material
The materials of refrigerated car compartments are mainly divided into "inside and outside plates" and "insulation materials".
Inside and outside plate
The common inner and outer plates for refrigerated cars in daily life include: glass plates, color plates, stainless steel plates, and aluminum profiles. The cost of raw materials such as color steel plate is relatively low, but it is easy to make cold bridges in the thermal insulation cabin, resulting in running cold and affecting the thermal insulation effect. This will not reach the conditions for some special cargo transportation, and sometimes it may not be lost. In addition, the upper layer of the glass plate material is the most popular and effective choice. Therefore, if you need to keep the temperature low, do not choose a relatively inexpensive color plate. The temperature of the flow is also the cost.
Insulation materials
Refrigerated car compartment commonly used insulation materials are: polyurethane, polystyrene board, extruded board. The same thickness of polyurethane heat preservation effect is better than polystyrene board. Polystyrene plates are used for cold storage plates, but they are mostly over 200mm, but because of the low cost of polyphenylene plates, many owners nowadays often use them for low prices. If you want to transport green fruits and vegetables and other low-temperature requirements, you can use it, but don't think about frozen products. The quality may still be beautiful when you load the car, but when you arrive at the destination, the car may smell It is a stench. Another extruded board is now an emerging material with low cost but good insulation. Because the flatness itself is guaranteed, the bonding effect is also better. This should be what everyone calls a cost-effective material, there are many manufacturers have begun to use. Companies are pursuing low-cost, high-profit materials, so this can be the best choice for manufacturers!
