The material of the sealing strip is the core factor that determines the service life. There are many types of environmentally friendly plastic products, the most common ones are silicone, PVC, etc. Different materials have different physical properties. Silicone material has good elasticity, high temperature resistance, and strong anti-aging ability. In long-term use, it can maintain good flexibility and sealing performance; while PVC material has a lower cost, but is relatively inferior in weather resistance and anti-aging. If the sealing strip is made of recycled materials or inferior raw materials, even if it is marked with environmentally friendly properties, its molecular structure is poorly stable and easily aged under light and temperature changes, and its service life is naturally greatly reduced.
The use environment has a significant impact on the life of plastic products environmentally friendly wooden door sealing strip. Long-term exposure to direct sunlight will cause the sealing strip to degrade due to ultraviolet radiation, and the surface will become hard, brittle, and lose elasticity; in a humid environment, the intrusion of water will reduce the performance of the material and accelerate the aging process; in areas with large temperature differences, the sealing strip will frequently expand and contract, the internal structure will gradually loosen, and the sealing effect will also weaken. In addition, if there are chemical gases and corrosive substances in the space where the wooden door is located, even if the sealing strip is made of environmentally friendly materials, the service life may be shortened due to chemical erosion.
Whether the installation process is standardized is directly related to the durability of the sealing strip. If the sealing strip is not tightly fitted with the door frame and door leaf during installation, there will be gaps or distortions, not only will it not be able to achieve a good sealing effect at the moment, but it will also cause uneven local force. In the process of frequent opening and closing of the door, the parts where the force is concentrated will accelerate wear, and the sealing strip that could have been used normally may be damaged in advance due to improper installation. At the same time, improper use of installation tools, such as scratching the surface of the sealing strip with sharp tools and destroying its protective layer, will also make it easier for external factors to erode the inside of the material.
Daily use habits have a subtle effect on the life of the sealing strip. Frequent and forceful opening and closing of doors will cause the sealing strip to be subjected to severe impact and friction, accelerating its surface wear; if foreign objects such as paper and cloth are often caught when closing the door, it will not only instantly increase the force on the sealing strip, but may also cause local deformation. In addition, if you do not pay attention to cleaning the dust and sand in the door gap, these particles will act like sandpaper and constantly scratch the surface of the sealing strip during the opening and closing of the door. Over time, the surface of the sealing strip will be worn through, the internal structure will be exposed, and the aging speed will be greatly accelerated.
The frequency and method of maintenance are crucial to extending the life of the sealing strip. Regularly cleaning the surface of the sealing strip to remove stains such as dust and oil can reduce the erosion of the material by external substances; applying protective agents to the sealing strips in a timely manner can form a protective film on its surface to enhance its anti-aging ability; timely checking whether the sealing strips are loose or displaced, and re-fixing them after discovering the problem can avoid local excessive loss due to position deviation. On the contrary, long-term neglect of maintenance and failure to promptly handle the aging of the sealing strips will cause the problem to continue to worsen and further shorten the service life.
The degree of compatibility between the plastic products environmentally friendly wooden door sealing strip and the wooden door also affects the service life of the sealing strip. Different types of wooden doors, such as swing doors and sliding doors, have different requirements for the specifications and shapes of the sealing strip. If the sealing strip does not match the card slot of the wooden door, it is easy to fall off if it is too loose, and it will increase wear if it is too tight; the quality and stability of the wooden door itself will also be affected. If the wooden door is not smooth due to moisture and deformation, it will increase the workload of the sealing strip and accelerate its aging under abnormal conditions.
Even under ideal conditions, the plastic products environmentally friendly wooden door sealing strip has a certain service life limit. With the increase of use time, the molecular chain inside the material gradually breaks, and the physical properties inevitably decrease. At this time, even if maintenance measures are taken, it can only slow down the aging speed, and cannot fundamentally reverse the decay process of the material. When the sealing strip is severely hardened, cracked, and loses elasticity, it means that its service life is coming to an end, and a new sealing strip needs to be replaced in time to maintain the sealing, sound insulation and other functions of the wooden door.
