The so-called aluminum clad wood doors and windows, simply speaking, means that the inner base material is wood, and the outer is covered with a layer of aluminum, which is mechanically compounded with wood. It combines the advantages of wood and aluminum. It not only has the natural and beautiful texture of wood itself, but also strengthens the performance of pure wood windows such as resistance to sunlight, wind, rain, and so on, eliminating all concerns about wood products.
Tips: There is also a wood aluminum composite window frame on the market. Although its cost is much lower, it is essentially different from aluminum clad wood. Aluminum clad wood window, the main body is wood, and aluminum is hung outside, which is more wood than aluminum; However, the wood aluminum composite window is less wood and more aluminum, which is actually a "false wood window", which belongs to the aluminum alloy window with wood boards hanging inside.
1. Thermal insulation
As we all know, the main material of aluminum clad wood is wood, which has a good role in heat insulation. Let's make a data comparison between aluminum clad wood window and plastic steel window and aluminum alloy window: since the main material of aluminum clad wood is wood, the thermal conductivity of wood is only 1.3, while that of plastic steel window is 2.2, and that of aluminum alloy window is 3.0. Comparatively, the data gap is huge. It can be seen that aluminum clad wood has obvious advantages!
2. Energy conservation and environmental protection
The energy conservation and environmental protection of aluminum clad wood windows and doors in Yantai refers to the comparison of energy consumption when processing window frames. The comparison of energy consumption of aluminum alloy windows, plastic steel windows and aluminum clad wood windows is 20:8:1. In terms of production energy consumption, aluminum clad wood is more energy efficient. On the base materials used, aluminum alloy window frames are derived from non renewable aluminum mineral soil, and plastic steel windows are derived from non renewable oil. Because wood windows are natural life forms and are derived from renewable wood, they are inexhaustible resources as long as they are reasonably exploited.
Anti corrosion and pest control
Aluminum clad wood doors and windows are vulnerable to microbial and bacterial damage because the wood contains certain sugar, starch, protein, etc. Therefore, wood needs to be treated to prevent corrosion and mildew. In southern China, when the air is humid, the requirements for door and window paint will be higher, and the effect of insect and termite prevention will be required, otherwise the following unacceptable aluminum clad wood products will occur, and termites will breed in the wood.
Waterproofness
When the wood moisture content of aluminum clad doors and windows exceeds 20%, the wood is easy to deform, even mildew and deform, so the water-based paint must have a good waterproof function.
The doors and windows have purchased advanced humidity measuring instruments to automatically detect the humidity in the warehouse. Once the humidity deviates, the equipment will automatically detect and respond to the humidification or dehumidification system.
Air permeability
While ensuring the waterproof of water-based paint, it is necessary to have a certain degree of permeability, otherwise, the paint film will bubble and fall off. It is necessary to balance the air permeability and sealing of aluminum clad wood door and window coating. Waterborne paint spraying of doors and windows can achieve one-way breathing: the water outside the wood does not enter the wood, while the water inside the wood can volatilize.
Weatherability
Yantai aluminum clad wood doors and windows paint film has a certain degree of elasticity and toughness, while UV resistance. The lignin contained in wood is vulnerable to ultraviolet radiation. Under the action of ultraviolet light, lignin will change color, wood will become brittle, strength will be reduced, and the adhesion of water-based paint will disappear. Whether in the artificial aging experiment or natural experiment (1 year), the weatherability requires that the water-based coating does not crack, fall off, bubble, and has good adhesion.
