Several common maintenance measures for refrigerated truck maintenance. The refrigerated car body is usually subjected to external force in the application process, resulting in damage to the car body, especially because of the excessive height bar or poor light or unfamiliar road conditions, and the collision of the vehicle, resulting in damage to the refrigerated car body, then what is the common damage and repair method of the refrigerated car body?
First, several common injuries of refrigerated car body
The internal and external skin of the domestic refrigerated car is mostly glass steel plate, and the middle layer is basically polyurethane insulation material, so the common damage of the domestic refrigerated car body is: scratches and cracks in the internal and external skin, the thermal insulation layer of the body is damaged, and the internal and external skin of the car is stripped of a small area.
2. Repair measures for several common losses of refrigerated car body
(1) Repair of damaged insulation layer of refrigerated box body
Due to impact or other reasons, the insulation layer is damaged, which is very likely to make the refrigerated car body lose thermal insulation performance. Most of the repair methods for refrigerated trucks are to cut off the damaged part of the insulation layer in a small area, and make polyurethane insulation material and glass plate of the same size, cover the insulation material with glass fiber felt and coat it with unsaturated polyester glue, paste the internal and external glass plate, and place it in the hole of the cut car plate, and fix it together with the whole car plate with external force. About 1 to 2 hours after the glue solidifies, repair and spray paint treatment.
(2) Repair of scratches and cracks on the skin inside and outside the refrigerated compartment
Scratches and cracks on the outer skin of the refrigerated car will directly affect the appearance of the car body, while deep scratches and cracks on the inner skin of the refrigerated car may affect the insulation performance of the insulation car body. The repair method of refrigerated truck maintenance is to first polish scratches and cracks into a rough surface, and then evenly apply the mixed atomized ash on it, and then smooth the atomized ash after drying, and spray paint.
