How Is The Refrigerated Compartment Made

Preparation materials, different materials, different requirements

Just as building a house requires preparation of materials in advance, assembling a freezer also requires preparation of materials. The most important one is the “sandwich” plate. The outer two layers of the plate are the same material, called “glass reinforced plastic”, and the glass reinforced plastic is made of The product that solidifies after the gel coat and the glass filament are mixed, a very thin layer, the outer wall of the compartment we see is commonly known as "glass reinforced plastic" material.

There is also a layer of material filled in between the two layers of FRP. There are two kinds of materials commonly used: one is the honeycomb panel used for the RV. It is characterized by light weight and good thermal insulation effect. According to the factory personnel, this kind of The carriages of the plates are used in Hong Kong.

The other is our common PU board, PU is the abbreviation of Polyurethane, and the Chinese name is polyurethane. Since only a simple modification of the formulation is required, different physical properties such as density, elasticity, and rigidity can be obtained. At present, a large number of glass fiber insulation materials, wood, and traditional rubber products have been replaced.
