The advantages of aluminum-plastic pipes can be summarized into three aspects. Outstanding hygienic performance: The inner and outer layers of the aluminum-plastic pipe are made of special polyethylene material, which is clean and non-toxic. The most important thing is that the middle layer of the aluminum-plastic pipe is aluminum, which can not only block light, but also block oxygen. As we all know, the environment of evil microorganisms must have light and oxygen. The middle aluminum layer of the aluminum-plastic pipe prevents the growth of microorganisms and algae, which is beyond the reach of the all-plastic pipe. The all-plastic pipe not only adds a lot of antioxidants to prevent the material from degrading, but the antioxidants are extracted into the water retained in the pipe, which is easy to cause water pollution, and because there is no light-blocking and oxygen-blocking material in the all-plastic pipe, it is very easy for microorganisms to grow. lead to secondary pollution of water quality. Excellent high and low temperature resistance: the long-term use temperature is 95 degrees (long-term durability according to standards, IMPa), the maximum use temperature is 110 degrees, and the thermal expansion coefficient of the aluminum-plastic pipe is small. It has a thermal expansion coefficient comparable to that of aluminum, and only one-sixth of that of an all-plastic tube. When the temperature changes, the deformation is small, and the aluminum-plastic pipe is a flexible coil, the pipe itself can digest a certain amount of deformation, and will not cause thermal expansion deformation of the pipeline system. The high and low temperature resistance of the all-plastic pipe is relatively poor. Long service life: The molecular chain structure (-CH2-CH2-) of the PE plastic used in the aluminum-plastic composite pipe is relatively stable among plastics, and since the aluminum layer in the middle of the aluminum-plastic pipe separates the inner and outer layers, the outer layer of plastic is allowed to be added enough to resist Stabilizer for light and oxygen aging without affecting the hygiene of the inner layer in contact with water, thereby enhancing its anti-aging properties.
