Wood flour applied art in general no big stringent requirements, various types of wood flour and a variety of plant fibers, etc. can be used in general (sawdust produced during wood processing, waste pulverized can be), to the impact of processing is not large, the main requirements of a variety of wood flour particle size is generally 20 to 100 mesh, on this basis, to ensure that wood flour and plastic for drying prior to mixing. Usually wood flour moisture content should be controlled within 3%. Drying equipment can be electric heating, microwave heating can also be drying or natural drying. non slip decking belfast
After drying the wood flour should be stored in that dry place (indoor), can not secondary to absorb moisture, otherwise it will process a greater impact. Need to mention that, when used with exhaust function of extruder, especially a twin screw extruder processing of wood materials, wood flour can not be a special drying process, simply to direct sunlight to dry naturally extrusion processing. For the wood processing wood processing is divided into two major categories of chemical and physical methods: chemical methods: outdoor deck railing plans
(1) surface grafting method: modified graft is an effective method, before the compound or complex grafted plant fiber simultaneously. As can with maleic anhydride, isocyanates and other grafted plant fibers. (2) interfacial coupling method: form a covalent bond with a coupling agent and plant fibers to change the interface adhesion. Such as silane coupling agents, titanate coupling agent, aluminum coupling agent and other treated fiber, fiber and resin to improve compatibility. The optimum amount of coupling agent and coupling cover the flour particles in the degree of the surface. If the coupling agent is too small, because the filler surface cladding is not complete, it is difficult to form a good coupling of the molecular layer, would not achieve the desired coupling and compatibilization. Amount too much, then the excess coupling agent in the surface will cover the excess flour coupling molecules form a multi-molecular layer, could easily lead to unevenness of the interface structure between the filler and the resin, and the unreacted coupling agent Other groups also have adverse effects, thereby reducing the mechanical properties of the composites. (3) acetylation treatment method: hydroxy plant fiber surface after treatment acetic anhydride or ketene, the polar hydroxyl group on the timber nonpolar substituted acetyl group to produce an ester. Acetic anhydride usually used in industry, glacial acetic acid, a mixture of sulfuric acid was acetylated. plastic wood bulgaria

With respect to the maintenance of Composite Rainscreen Cladding, the laminate wood floor maintenance much easier, how to care for laminate flooring? Let the peace of mind to teach the floor to you! 1. usually just wipe with a damp mop. But be careful to avoid damp and too sharp, too hot items to strengthen the composite wood floor damage.
2. Some special dirt, mild detergent can be used immediately or warm water wash, never use a lot of water for cleansing laminate flooring. No waxing and paint, do not use sandpaper polished. Because laminate flooring is different from the solid wood flooring, its surface was relatively smooth, brightness is relatively good, waxing the rather superfluous. 3. The daily life attention to small details, not the matches and cigarette butts thrown on smoothly on pebble look in plastic floor covering, laminate flooring once charred patch will seriously affect the appearance and it is very troublesome.
4. Avoid sharp objects, such as scissors, knives and the like scratching the surface of the floor; when moving chairs, tables and other furniture Do not drag; Cengdeng place a mat at the door, to avoid the gravel or other small stones on reinforced composite wood floor damage. 5. Avoid gum containing objects falling on laminate flooring, such as chewing gum, it would be difficult to clean up; in the bathroom and the kitchen door should always pay attention to clean up seeping water. In the northern region, due to the relatively dry climate, laminate flooring prone to cracks and cracking. So when the climate dried pay attention to proper humidity increases laminate flooring surface conditions can use specialized surface humidifier to increase humidity; cotton swab dampened with water can also be used to wring out wipe waterproof wooden outdoor decking.
