A:The aging of the plastic extruder is reflected in the wear and deformation of the mechanical structure, such as the increase of the clearance of the screw barrel and the fatigue deformation of the frame. Electrical system aging failure and performance decline, wire and cable and components easy to fail; Production efficiency decreases, extrusion volume decreases and energy consumption increases. The product quality is unstable, the defects increase, the rejection rate rises, affecting the economic benefits of enterprises and the production process.
A:Plastic pipe cutting machine maintenance is very important. When using, pay attention to ensure that the power line is safe and reliable. Wear suitable work clothes, workpiece clamping firmly. Do not trim burrs on the surface of the grinding wheel. Remove dust and debris in time, clean the ash accumulation parts and cooling system, check the lubrication system. If conditions exist, the cylinder can be cleaned regularly to ensure the health of the equipment, extend its service life, and ensure the efficient cutting work.
A:The grain size of wood powder affects the properties of wood plastic products. Fine wood powder can strengthen the bond with plastic, improve the strength and dimensional stability of the product, but may reduce the toughness. The coarse wood flour reduces the density of the product and the dimensional stability is poor, but the fluidity is better. In addition, the surface of fine wood powder products is smoother and the color is uniform; Coarse wood flour is coarser. It is necessary to select the appropriate particle size wood powder according to the demand to optimize the performance of the product.
A:The main raw materials for the production of wood-plastic products are wood flour and plastic. Wood flour is usually made from wood processing leftovers, which is environmentally friendly and gives products a natural texture. Plastics mostly use polyethylene, polypropylene, etc., with good corrosion resistance and processing properties. Combined with the two, the wood-plastic products produced have the advantages of wood and plastic, such as waterproof, anti-corrosion, durable, etc., and are widely used in buildings, gardens and other fields.
A:The selection of suitable wood plastic door production line needs comprehensive consideration. First identify the output and product specification requirements, and then evaluate the technical process, such as extrusion and molding methods. Focus on equipment quality, including materials, construction and control systems. The strength of the manufacturer and after-sales are also key, and field visits are necessary. Combined with the cost budget, but also look at the quality of the sample, multiple comparison can choose the ideal production line.
A:Extrusion molding of plastic profiles is to extrude the molten plastic through the extruder, and then through a specific mold and setting device, so that it is cooled and solidified into a plastic profile with a specific shape and size. This process requires precise control of parameters such as temperature and speed to ensure product quality. Widely used in building materials, automobiles, electronics and other fields.
