In the process of global economic integration, Yongte Company has continuously expanded the international market with its outstanding technical strength and high-quality products. Recently, a batch of carefully manufactured Yongte PVC pipe equipment has embarked on a journey to Africa. Yongte PVC pipe equipment has established a good reputation in the industry for its high efficiency, stability and energy saving. This shipment to Africa is an important measure for Yongte Company to further develop the African market.
A:Drawing roller is the key component of drawing machine. It is usually made of metal and may have a rubber layer on the surface to increase friction. Its role is to generate enough traction through contact with the material to drive the strip forward at a constant speed to ensure the uniform size of the strip and good surface quality. The precision and performance of the traction roll directly affect the working efficiency and product quality of the stretcher.
Recently, Yongte WPC door frame extrusion line embarked on a journey to India. This shipment marks a solid step for Yongte in expanding the international market. Yongte has always been committed to the research and development and production of high-quality WPC door frame extrusion lines. With advanced technology and strict quality control, its products are highly favored in the market. This shipment to India is a strong proof of the excellent quality and good reputation of Yongte products.
A:The key to the maintenance of plastic recycling shredder parts is to find the problem in time. Regularly check whether the blade is worn, the blade is broken, and the knife shaft is bent and deformed. If the reducer has abnormal noise, check the gear condition. Motor overheating or loose wiring should also pay attention. Find the problem timely repair, ensure the efficient and stable operation of equipment, reduce maintenance costs, improve production efficiency.
A:The temperature of the plastic extruder significantly affects the plasticizer effect. The temperature is too low, the plasticizer is difficult to disperse evenly, the plasticization is not sufficient, and the flexibility of the product is poor. When the temperature is moderate, the plasticizer can fully play its role, reduce the melt viscosity and improve the processing performance of plastics. Different plasticizers are affected by temperature differently. For example, phthalates have a good effect at medium temperature, aliphatic dibasic acid esters are volatile at high temperature and require low temperature, and polyesters need high temperature to promote dispersion due to their large molecular weight.
A:The principle of co-extrusion technology is to combine two or more different plastics using multiple extruders through a multi-channel composite die head to produce a composite film with multi-layer structure, and cooled by a casting roll. In the co-extrusion process, different plastic materials are plasticized separately in the extruder and are compounded with each other through the composite die head in an extrusion process to form a composite film with a multi-layer structure. This multi-layer structure can make the product have the excellent characteristics of different materials, and can complement each other in characteristics, so that the product can get the performance and appearance of special requirements.
