As our brothers in the built-in freezer know, the temperature-preserving material is right, and the shelf life and energy-saving effects are directly doubled! But there's a lot of material on the market. Today, we're not messing around, we're talking about real things -- you can be half a professional after reading the usual materials
First, the hard core polyurethane spray
It's called "golden oil" in the cold storage, and it's sprayed directly into the walls without even a stitch. Thermal coefficients are so low that they have the highest temperature-preservation effect and are particularly suitable for alien structures or for a large number of freezers. However, there was a small drawback: the construction had to be done by a professional team, and the risk of a later frost came up。
Polyurethane thermometers: pyramid installation
If you're in trouble, you go straight to the prefabricated plate! Polyurethane plate works like lego. The plate itself is self-retarded and safe. However, attention must be paid to the suture treatment, and if the glue is not properly applied, the air conditioner slips out of the suture in a minute, and the electricity costs rise。
Squeeze the board: the king of prices
Look here! The price of the squeezing board is pro-people, the resistance is high, the frozen floor floor is bottomed with it, and the forklift is run over. However, the density is too low, otherwise the time is too long to be deformed and temperature-preservation can be compromised。
Polystyrene foams: light but delicate
It's light material. It's hard to move? It doesn't exist! But don't look at it as cheap. It's almost damp. If the temperature of the freezer fluctuates, such as frequent frosting, it is recommended to go around。
Glass cotton/rock cotton sheeting: fire safety smallpox board
A freezer next to a warehouse or a crowded area? Fire protection must be severed! The glass cotton and the rock sheet are classified as non-fired material of class a, and the fire control is done directly. However, fibres are easily defusing, the construction is carried out under a mask and the post-maintenance maintenance has to be performed quickly, and the temperature is high enough to jump。
A guide to the selection of materials to avoid pits
Finally, focus: don't just look at material parameters, but combine the use of cold storage! For example, seafood freezers are highly wet and preference is given to tideproof ones; meat freezers have low temperatures and have to withstand the freezing loop. And teach me another trick -- ask the manufacturer to test the report, and the heat coefficient, burn level data must be clearly written in black and white, and don't let the sales talk slip
