简体中文There are generally four types of materials for central air-conditioning outlets: wood, aluminum alloy, 'ABS' and hard PVC materials.
1. Aluminum alloy material
Aluminum alloy tuyere is more commonly used in existing household central air conditioner users.
(1). When cooling in summer, if the temperature of the air supply is too low, the insulation is not done well during construction, and the air volume is too small, etc., condensation will occur at the tuyere, and water droplets will appear in severe cases Zhejiang Junlan Zhenpin Artistic carved air conditioner air outlet.
(2). The aluminum alloy material profile is cut, welded, painted, baked and other multiple production processes. The hazards of paint are well known. A tuyere slowly releases formaldehyde through the air during the cooling and heating process, which will affect your health unconsciously.
2. PVC material
PVC is actually a vinyl polymer substance, and its material is a non-crystalline material. Now when used in household central air conditioners, there is less condensation; it is non-flammable, high-strength, weather-resistant, and has excellent geometric stability. PVC has strong resistance to oxidizing agents, reducing agents and strong acids; rigid PVC material has a high density (ABS≈1.04, rigid PVC≈1.04), and the same size and area of the tuyere, 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. The difference between ABS and PVC tuyere profiles is to burn them with fire, ABS starts an open flame (additional materials can be smoldering), PVC is flame retardant and emits black smoke.
3. ABS profile material (plastic steel tuyere)
PS foam board + alloy material; plastic extruded profile is a new type of material "replacing wood with plastic". It uses polyvinyl chloride (PVC) as the main raw material and is made by a special foaming process. The product has moisture-proof, Flame retardant (self-extinguishing), constant shape, non-toxic, beautiful, strong anti-aging ability, etc., and has excellent corrosion resistance, weather resistance, anti-corrosion, waterproof, sound insulation, heat preservation, insulation and other outstanding advantages, and can be customized according to user requirements. The profiles can be assembled into tuyeres of various styles and sizes according to decoration needs, but the PS-type material tuyere has many procedures for connecting and assembling, which is the main reason for its high price.
4. Wooden material
Wooden air vents are easier to integrate with the decoration in a specific decoration style. However, when heating in winter, due to the large temperature difference between the tuyere and the air conditioner when it is not in use, it is easy to deform, crack, and even mold and rot. The cost of cutting and assembling the wooden tuyere itself is not cheap, and the relative price is not low.
