[0025] In this embodiment, the polystyrene layer 501 provides lightweight, toughness, heat resistance, and chemical corrosion resistance, further enhancing the corrosion resistance of the plastic shell 3. It also offers high heat resistance. The polyethylene material layer 502 provides excellent barrier properties, effectively preventing the penetration of external substances such as oxygen, moisture, and odors, and preventing external moisture from entering the interior of the plastic shell 3. It also offers high corrosion resistance. The resin coating 601 and flame retardant coating 602 release non-combustible gases or form a heat insulation layer at high temperatures, thereby preventing or slowing the spread of flames. The resin coating 601 provides adhesion and durability to the coating, while pigments, fillers, and solvents are used to adjust the physical properties and application performance of the coating. The strength layer 4 significantly improves the tensile strength, flexural strength, and impact strength of the plastic. Tensile strength refers to the material's ability to resist fracture during stretching, further enhancing the overall strength of the plastic shell 3.

[0029] The working principle of the corrosion-resistant fire smoke detector provided by this utility model is as follows:

[0030] Implementation steps for the first innovation point:

[0031] Step 1: By setting the polystyrene layer 501, which has the characteristics of being lightweight, tough, heat-resistant, and chemically resistant, the corrosion resistance of the plastic shell 3 is further increased, while also having a high heat resistance.

[0032] Step 2: The polyethylene material layer 502 has good barrier properties, which can effectively prevent the penetration of external substances such as oxygen, moisture, and odors, and prevent external moisture from entering the interior of the plastic shell 3. It also has high corrosion resistance. The resin coating 601 and flame retardant coating 602 can release non-combustible gases or form a heat insulation layer at high temperatures, thereby preventing or slowing down the spread of flames. The resin coating 601 provides the adhesion and durability of the coating, while pigments, fillers and solvents are used to adjust the physical properties and workability of the coating.

[0033] Step 3: By setting the strength layer 4, the tensile strength, flexural strength and impact strength of the plastic can be significantly improved. Tensile strength refers to the material's ability to resist fracture during the stretching process, which further improves the service strength of the plastic shell 3.
