1) Waterproof, moisture-proof, anti-corrosion, mildew proof, moth proof, and non deformable wood plastic products have the dual characteristics of wood and plastic, so wood plastic suit doors are especially suitable for places with large temperature difference, humidity, and poor ventilation, such as wet toilets, storage rooms that need anti-corrosion, mold proof, and moth proof, in addition to being used outside indoor rooms. 2) The special cavity structure design with reasonable structure and high strength ensures the ideal internal structure of wood plastic foam material. In addition, the excellent formula design and reasonable production process ensure the strength of the product.3) Fast installation structure, time-saving and labor-saving installation, the wood plastic door adopts the fast installation structure introduced from Germany, and the installation of the door pocket is extremely convenient. The door pocket line and the door pocket are connected by bayonet, without the need for gun nails or adhesive fixation. 4) Good thermal insulation and sound insulation performance The materials used for wood plastic door sets have uniform and fine bubbles and specially designed cavity structure, which ensures that their thermal conductivity is lower than that of ordinary plastic materials and their noise reduction performance is good. The test shows that the heat transfer coefficient of the product is 1W/m2. k, and the thermal insulation performance reaches Grade I of GB/T16729-1997; The sound insulation performance grade is Grade 6, with good heat preservation and sound insulation performance. According to the test, the oxygen index of Longqiao wood plastic suit door is 48, and its fire protection performance is B1. This performance of Longqiao wood plastic suit door will greatly improve the fire safety of residential buildings.
