形しているのが現状である。(b) Conventional technology In the case of drain pans made of expanded polystyrene, the inner surface is covered with a thin polystyrene sheet to increase strength and prevent water leakage, as proposed in Japanese Utility Model Publication No. 50-32356. Currently, nofan casings are made only from styrofoam, without using styrene sheets.

In the case of drain pans, the drain water generated in the evaporator during cooling operation of the air conditioner contains oil and solvents, so this drain water corrodes the pan, causing water leaks.

明した。(e) Function: As the resin material for the film covering the surface of the styrene resin molded product, it is necessary to select a material that has excellent chemical resistance (not being attacked by oil or solvents) and does not corrode the styrene resin. After fully considering this point, we decided to use the resin material for the coating.
Solvent-free epoxy resins and water emulsion coated acrylic resins are the most suitable.Although solvent-based epoxy resins and acrylic resins have chemical resistance, the solvents of these resins corrode styrene resins, so they are not suitable. It turned out that it wasn't.

ことにより行なわれる。The film can be formed by molding a drain pan or fan casing using Styrofoam, and then applying a solution of a solvent-free epoxy resin or a water emulsion type acrylic resin dispersion to the surface of the drain pan or fan casing. This is done by immersing it in a resin solution to make it adhere, and then drying it.

It may be covered with

Apply a solvent-free epoxy resin solution or a water emulsion type acrylic resin dispersion to the Nadren pan (6) and fan casing (4) with a spray gun and dry it with a film that covers the surface. Alternatively, it is formed by immersing the drain pan (6) and fan casing (4) in these resin liquids and drying them.

Because it is covered with silica, it will not be eroded by oil or solvents.
