Although the cost is reduced, and the bolt is not easy to crack in the whole process of riveting, and the difficulty coefficient of engineering construction is small, the compression strength of riveting is abandoned, and the service life of refrigerated transport vehicle is missing. After all, refrigerated transport vehicles drive on the road every day, and the real-time road conditions are different. Only bolts with high compressive strength can be integrated into various real-time road conditions.

The problem of using adhesive to replace bolt

The fourth problem is whether the development trend of bolt replacement with adhesive is in the future. From a global perspective, a small number of manufacturers of lantern rivets in the refrigerated transport vehicle manufacturing industry have already used adhesives to replace bolts to connect the inner side plate, and most manufacturing enterprises still use rivets to connect the inner side plate. At present, the bolt riveting method is adopted for the inner side plate foundation of refrigerated transport vehicles in China and South America, and the sealant is selected at the place where the plates are assembled. This kind of production and processing technology is characterized by convenient construction and firm connection. In Europe, some refrigerated transport vehicle manufacturers prefer to use high toughness adhesives for engineering construction.
