In the process of home decoration often used wood plastic composite decking board, so you know what the specific raw materials? Wood-plastic board is actually made of wood and plastic composite artificial board. It has some of the properties of wood and plastic. This article introduces to everybody, its synthesis principle and main performance, as well as the choice of wood plastic composite decking board raw material. The concept of wood plastic composite decking Wood plastic composite material is a kind of is mainly composed of wood, wood fiber, plant fiber) on the basis of material and thermoplastic polymer material (plastic) and processing AIDS, etc., after mixing heating extrusion mold equipment, made of a high-tech green environmental protection material, performance and characteristics of both wood and plastic, can replace a new type of composite wood and plastic materials. The material composition of WPC decking The corner of the wood-plastic plate was mostly abandoned wood slag powder, chopped wood and wood, has good stiffness and toughness, can be nails, drilling, sawing, planing, grinding, paint, and not easy deformation, crack prevention, it is furniture, interior decoration industry, packaging industry, vehicle interior industry and future housing industry preferred green wood plate, will start a new revolution in plate market. Processing technology of wood plastic composite decking Outdoor wood-plastic plate with the same processing characteristics as wood, the use of ordinary tools can be sawed, drilling, nail, very convenient, can be used like ordinary wood. At the same time, it has the wood feeling of wood and the water-resistant and anticorrosive properties of plastic, making it a kind of excellent and very durable outdoor waterproof and anticorrosive building materials (wood-plastic floor, wood-plastic wall board, wood-plastic fence, wood-plastic chair and stool, and wood-plastic landscape engineering, etc.). Main properties of WPC Hollow Decking 1. Physical properties: good strength, high hardness, anti-slip, anti-wear, anti-cracking, anti-moth, low water absorption, anti-aging, anti-corrosion, anti-static and ultraviolet, insulation, heat insulation, flame retardant, can resist 75℃ high temperature and -40℃ low temperature. 2. environmental performance: no toxic substances, dangerous chemical components, preservatives, etc., no formaldehyde, benzene and other harmful substances release, will not cause air pollution and environmental pollution, can be 100% recycled and re-processed for use, but also biodegradable. 3. Appearance texture: it has the natural appearance and texture of wood. Better than wood dimension stability, no wood knot, will not produce cracks, warping, deformation, products can be made into a variety of colors, the surface without the second coating paint can also be long lasting new color. 4. processing performance: with wood secondary processing, such as sawing, planing, bonding, with nails or screws fixed, all kinds of profile specifications and standards, quick and convenient construction and installation. Through routine operation, can be processed into various facilities and products.
1. Preparation before the construction of the wood plastic composite floor; before the construction, make sure that the concrete base of the construction site is smooth. This is very important, hope we do not want to save trouble, reluctant construction, otherwise cause you will lose more than you gain. 2. the center of the keel distance control in 310-410mm, the keel end butt joint should leave 10mm or so of the spacing, facilitate drainage, at the same time to achieve the keel row and row between the end seam staggered, not in a straight line. The allowable error of keel spacing is <10mm, the flatness is <3mm, and the expansion joint between the keel and the wall is 8-10mm. 3. the construction site base ground construction conditions are poor, can not achieve the topic structure stability, need to use steel keel instead of wood plastic composite keel, the use of galvanized steel, welding links to remove welding slag backseat rust treatment. 4. the size of floor splicing gap, want to be installed according to wood model floor when the temperature and humidity of the environment, floor length, floor moisture content, and laid area specific case reasonable determination. WPC hollow decking installation notes 1. Due to the high density of wood-plastic material itself, drill is required to guide holes in the positions where self-tapping screws are used, and then tighten the self-tapping screws. 2. Requirements for fixed keel: the installation working face shall be smooth without potholes and the keel spacing L shall be between 300mm and 350mm. 3. for a large area of wood - plastic floor pavement, it is recommended to use the graphic installation, the length of each wood plastic composite floor is not more than 2 meters. 4. Edge sealing 5. For the pavement of the curved wood-plastic floor, the two ends of each piece of the wood plastic composite floor shall be cut according to the length and Angle of the curved road and then paved. 6. The wood plastic composite floor of the steps is paved, and it is recommended to protect the wood-plastic floor with metal layers for the positive corner of the steps. 7. in the use of the process, please avoid the impact of heavy objects or collision. In the process of storage, transportation and installation of materials, please pay attention to proper handling to prevent it from falling from the height of the damage.
The comprehensive performance of wood plastic composite decking materials is very excellent, and more and more varieties of WPC materials are used in outdoor buildings and landscape, and the quantity is also increasing. With the continuous progress of manufacturing technology and technology, the appearance quality of products has been greatly improved. However, during the rainy season, the wood plastic absorbs water and expands, and the wood plastic composite decking material produces slight creep elongation, which cannot be recovered. The creep elongation and superposition are produced periodically with the alternation of dry and wet periods. As the wood in the WPC reaches the possible water-absorbing expansion limit and the binding effect of polymer materials, the increment of water-absorbing expansion creep elongation decreases to zero and reaches the creel limit. wood plastic composite decking material creep is temperature stress creep superposition and swell creep the comprehensive result of a long WPC ends are fixed constraint, along with a variety of WPC material creep superposition, beautiful linear materials when built, gradually apparent bending; And after a number of heat and cold alternation, the size is basically stable and the bending degree is no longer increased. Solution to the wood plastic composite product of water absorption expansion In WPC materials, the moisture absorption of the macromolecular base is small, and that of plant fibre is large. It is important to treat plant fibres effectively to minimize moisture absorption. In the formulation design and process design of wood plastic composite materials, the water absorption of WPC materials should be reduced as much as possible, and the strict water absorption rate should be regarded as the quality index.
