Processing technology of thermal insulation board for refrigeration

Abstract

The invention discloses a processing technology of a thermal insulation board for refrigeration. The structure technology adopts a structure of an inner skin, an outer skin and inner glass fiber reinforced plastic profile is adopted, the inside adopts a glass fiber reinforced plastic profile framework, and a foaming material is injected into a cavity formed by the glass fiber reinforced plastic profile framework to form a van board of a thermal insulation layer. According to the processing technology of the thermal insulation board for refrigeration, the thermal insulation board for refrigeration consists of inner skin glass fiber reinforced plastic, a high strength structural adhesive, a glass fiber reinforced plastic profile cavity and outer skin glass fiber reinforced plastic from the inside out in order, has good corrosion resistance and heat preservation, and the appearance is bright and clean. The glass fiber reinforced plastic profile is taken as the cavity, no other complex production process is needed, the production efficiency is improved, and the cost is lowered. The processing technology of the novel high temperature van board provided by the invention has the advantages of high production efficiency, high product quality and good product quality stability, simple process and convenient operation, and is suitable for small and medium-scale industrial production.

Description

technical field [0001] The invention belongs to the field of production of thermal insulation compartment panels, and in particular relates to a processing technology of thermal insulation panels for refrigeration. Background technique [0002] In the prior art, the main production methods of insulation compartment panels for refrigerated and insulated vehicles include the following three types: foam filling, dry-wet combination, and pure dry panel production. [0003] Foam filling type: The production process is to place height-limiting blocks in the middle of the upper and lower skins. The internal structure needs to be made in advance and fixed on one side of the inner skin, and then sent to special equipment and filled with self-foaming PU glue. Using equipment and height-limiting blocks Determine the thickness of the board, do not use adhesive itself, only use the self-adhesive properties of the foam to connect the skins on both sides. There are many types of inner and...

Problems solved by technology

The disadvantages are: 1. Because the skin is prefabricated, the sides of the board are open. Generally, in order to cover up this defect, most manufacturers will seal the end face or use profiles to cover it up.

2. The strength of the board is low, and it is difficult to repair. In case of special structures (such as meat trailers), it can only be implemented by prefabricated board inner frames. Relatively speaking, the weight is relatively heavy, and the design is not strong, and the later maintenance and repair costs are high.
