Why should kitchen door and aluminum alloy bathroom be chosen? In fact, the reason is very simple. Toilets and kitchens are relatively humid places, and wooden doors are not suitable for use. If wooden doors are damp and moldy, many people will think of plastic steel doors that can be used. Let's compare plastic steel doors with aluminum alloy doors to see which kind of doors are more suitable for use in kitchens and bathrooms.
1. Wind pressure strength and water tightness
Due to the low strength and rigidity of plastic steel window, the wind pressure resistance and water tightness of plastic steel window are two grades lower than that of aluminum window. Moreover, because the lining steel of the plastic steel window is not connected into a complete frame system in the inner cavity corner of the profile, the strength of the plastic welding angle of the window frame, the four corners of the fan and the T-joint is relatively low.
2. Air tightness
As the frame and fan components of plastic steel window are welded, the air tightness of plastic steel window should be slightly better than that of bolted aluminum alloy window. However, the dimensional accuracy of aluminum window profile is higher, and the frame and fan fit closely, so they are still at the same level.
3. Thermal insulation performance
The thermal insulation performance of aluminum window is not as good as that of plastic steel window. When taking a bath, the heat consumption is smaller!
4. Daylighting performance
The lighting performance of plastic steel window is worse than that of aluminum window. The shading area of single component of plastic steel window is about 10% larger than that of aluminum window. The visual field and decoration effect are poor, which is not conducive to building lighting energy conservation and consumption reduction. Kitchen and toilet is originally in the backlight of the house type! Daylighting performance can not be ignored.
5. Sound insulation performance
The gap sealing level of aluminum window and plastic steel window is basically the same, and their sound insulation performance is also basically the same.
6. Fire performance
The fire resistance of PVC plastic steel window is better than that of combustible wood window, but it is worse than that of non combustible aluminum alloy window.
7. Aging problem
The PVC plastic profile will be aged. The macromolecular chain of high molecular PVC resin will be broken under the action of ultraviolet radiation, which will make the surface of the material lose luster, change color and pulverize, and the mechanical properties of the profile will decline. Aluminum alloy has the function of anti-aging.
8. Deformation and expansion
Plastic steel windows are easy to deform when heated and brittle when cold, and have poor dimensional and shape stability. The rigidity of glass is often used to prevent the deformation of window frames. Aluminum alloy has the advantages of high temperature resistance and deformation resistance.
Based on the above analysis, I think everyone's psychology has an answer. Comparatively speaking, aluminum alloy door has better performance than plastic steel door, which is more suitable for use in kitchen and toilet.
