A, wood material:

The wooden central air-conditioning vent is easier to integrate with the decoration in a specific decoration style. However, when heating in winter, due to the large temperature difference between the air outlet when using and not using the air conditioner, it is easy to deform, crack, and even moldy and rot.

B. ABS profile material (plastic steel air outlet):

Foamed sheet + alloy material; plastic extruded profile is a new type of material that "replaces wood with plastic". It uses polyvinyl chloride (PVC) as the main raw material and is made by a special foaming process. The product is moisture-proof and difficult to use. It has the advantages of burning (self-extinguishing), unchanged shape, non-toxic, beautiful, strong anti-aging ability, and has excellent corrosion resistance, weather resistance, waterproof, sound insulation, heat preservation, insulation and other outstanding advantages. The profiles are assembled into various styles and sizes of tuyere according to the decoration needs, but the PS-type material tuyere has many production processes, which is the main reason for its high price.

C. PVC material:

PVC is actually a vinyl polymer, and its material is an amorphous material. When used in household central air conditioners, there is less condensation; it has non-flammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids; rigid PVC material has a high density (ABS≈1.04, rigid PVC≈1.04), the same size and area of ​​the air outlet, the weight is ABS, aluminum alloy About 1.5 times, the impact strength is also inferior to ABS material, but the price is slightly lower.
