Titanium alloy sliding door, two doors, three doors and four doors. How to calculate the blanking size?

Wooden doors are divided into solid wooden doors and artificial wooden doors. The artificial wooden door is made of wood fiber board, and the deformation coefficient is relatively small. As long as it fits perfectly after installation, the size is regular and the installation is fine, there will be no obvious changes in the future. Solid wood door: At present, the definition of solid wood door is that as long as the core material of the door is not particleboard, it can be called solid wood door. Domestic solid wood doors generally use solid wood or high-quality core board as the keel of the door, and then, wood-based panels are sealed on both sides. If you are going to paint the surface with varnish, you should also paste a layer of veneer plywood on the surface. This plywood has the unique phenomenon of natural wood, which is thick and expensive, of high quality, and is not easy to crack and deform, but its price is on the high side. Solid wood doors are made of natural logs in the forest after drying, cutting, planing, tenoning, drilling and high-speed milling. Solid wood doors are mostly precious wood, such as cherry, walnut and teak. The finished door after processing has the characteristics of no deformation, corrosion resistance, no cracking and heat insulation. At the same time, the solid wood door has good sound absorption and effectively plays the role of sound insulation. The disadvantage is that it is expensive and easy to deform, so it is not suitable for use in the north. It's too heavy. It's easy to deform when wet. Poor fireproof and waterproof performance. "Ecological Gate" is a concept derived from "Ecologist". Eco-home originated in some developed countries in Europe that pay attention to ecological protection. It is a comprehensive environmental concept, including various comprehensive factors: sound, light, water quality, geology, greening rate, disaster resistance and other natural environment; Ventilation, ventilation, sunshine, lighting, air cleanliness, temperature, relative humidity, building materials, decorative materials, construction technology and other indoor space environment. According to the ecological index, the indoor temperature should be kept between17℃ and 27℃, and the relative humidity should be kept between 40% and 70% all the year round. The key of ecological home is environmental protection and health, which is higher than the standard of "green home". It has not only hardware requirements, but also humanistic requirements, and pays attention to the harmony between man and nature. Personally, I think "ecological gate" should be an element of "ecologist". In this sense, the ecological door should pay attention to ecology and the harmony between man and nature, and it should be a product of humanity. Ecological doors should have more social connotations than solid wood doors and composite doors. Ecological door is based on nature, using natural conditions and artificial means to create a comfortable and healthy product that is conducive to living. In terms of materials, we should not blindly abuse natural resources, but use more artificial, composite and recyclable materials that are harmless to nature, so as to contribute to the whole ecological environment and establish a harmonious living environment. Cutting down trees at the expense of the natural environment is not a scientific ecological way, and its products are not an ecological door in a certain sense. The knowledge of internal structure is the ecological door in the market, mainly from the hardware structure and materials. In terms of structural materials, the door cover and the door edge are made of high-tech Al-Mg-Ti alloy, and the surface is anodized, which has a certain hardness and improves the wear resistance, compression resistance, deformation resistance and fading resistance. The inner door core plate usually adopts the bridge hole mechanical plate (the high-quality products adopt the bridge hole mechanical plate imported from Germany, followed by the domestic bridge hole mechanical plate), and the free formaldehyde emission of some eco-door products on the market can generally reach the internationally accepted European E 1 standard; At the same time, due to the unique structural characteristics of bridge opening mechanical board, the ecological door products using bridge opening mechanical board have been greatly improved in terms of sound insulation, heat preservation, external force resistance and self-weight. The door body structure of the ecological door is made of integral die casting, achieving seamless, sealing and sound insulation effects. As for the facade materials of the eco-door, different companies use different materials, including Tommy Tam metal plate (referred to as Tommy Tam metal series decorative plate), polymer organic plate, imported decorative plate, and even leather. No matter what panel, the most important thing is not to pollute the environment and strive for environmental protection. Take "Tommy Tam Metal Plate" as an example, it is a decorative plate with aluminum metal veneer. The base material is divided into density board, fireproof board and pure aluminum board. The thickness of density substrate varies from 3mm to 18 mm, and 3 mm is a decorative board, which is mainly used for various decoration wall backgrounds. Sliding door application board 5 mm-8 mm; 18mm is the door panel and storage cabinet, and the decorative partition can be folded at right angles. The thickness of refractory board substrate is 1mm, and the construction method of pure aluminum substrate is the same as that of general refractory board. At the same time, the surface treatment of Tommy Tam board also has many unique patterns, such as painting, relief, frosting and so on. , a collection of almost all the metal surface pattern treatments in the world today, provides consumers with more choices. Humanistic ecology is the biggest selling point. Judging from the current market situation, if the eco-door can truly reflect the effect of eco-home, it may be a revolutionary creation and subversive product in the field of interior doors, which will have certain cross-era significance. Because it not only makes environmental protection, simplicity, fashion and durability more perfect, but also gives more human factors, which are rare in other categories of products. The worst selling point of humanistic ecology door is much higher. Although customers like it when they see it, many of them will not spend a month's salary to buy it, and there are still many.
