Publish Time: 2025-02-27
In the production process of PVC (polyvinyl chloride) industrial textiles, in order to improve their surface properties, such as wear resistance, water resistance and aesthetics, special surface treatment is often required. Among them, the "three-coat three-furnace knife scraping" technology is an efficient and widely used process method. This article will introduce in detail the composition, working principle and advantages of the three-coat three-furnace knife scraping surface treatment production line for PVC industrial textiles.1. Production line compositionThe three-coat three-furnace knife scraping surface treatment production line for PVC industrial textiles is mainly composed of the following key parts:Unwinding device: used to place the PVC industrial textile roll to be treated, and control the unwinding speed and tension automatically or manually.Pretreatment device: Clean and dust the textiles to ensure that the subsequent coating can be evenly attached.First coating machine and drying furnace: The coating machine evenly applies the special coating on the surface of the textile, and then enters the drying furnace for rapid drying to solidify the coating into a film. This process is usually repeated three times, that is, "three coatings and three furnaces".Scraping device: After three coatings and drying, a scraping device is set up to finely treat the surface of the textile. The scraping device scrapes off the excess paint through a scraper to form a specific texture or pattern, while enhancing the adhesion of the coating.Cooling device: Cool the treated textile to stabilize the coating performance.Winding device: Wind the treated PVC industrial textiles into rolls for easy storage and transportation.2. Working principleThe working principle of the production line is relatively complex but orderly. The PVC industrial textiles to be treated start from the unwinding device, pass through the pretreatment device, and enter the first coating machine. The coating machine evenly applies the paint on the surface of the textile, and then the textile enters the drying furnace for drying. This process will be repeated three times, and the performance of the textile will be improved after each coating and drying.After completing three coatings and drying, the textile enters the scraping device. The scraping device finely treats the surface of the textile through a scraper, scrapes off the excess paint, and forms a specific texture or pattern. This process not only improves the aesthetics of the textile, but also enhances the adhesion of the coating.Finally, the treated textiles are cooled by a cooling device to stabilize the coating performance. After cooling, the textiles enter the winding device and are wound into rolls for subsequent use.3. Advantages of the production lineHigh efficiency: The three-coat three-furnace knife-scraping surface treatment production line can realize automated production, greatly improving production efficiency.High quality: Through precise coating, drying and knife-scraping treatment, the uniformity and adhesion of the textile surface coating can be ensured, and the product quality can be improved.Flexibility: The production line can adjust the type of coating, coating thickness and knife-scraping texture according to different product requirements to meet diverse market needs.Environmental protection: The use of advanced coating and drying technology reduces pollution to the environment and meets current environmental protection requirements.4. Application and ProspectThe three-coat three-furnace knife-scraping surface treatment production line for PVC industrial textiles has a wide range of applications in many fields, such as automotive interiors, furniture decoration, and building waterproof materials. With the advancement of science and technology and changes in the market, the production line will pay more attention to intelligent, green and personalized development in the future. By introducing advanced sensors, automatic control systems and environmentally friendly materials, production efficiency and product quality will be further improved to meet more diversified market needs.The three-coat, three-furnace scraping surface treatment production line for PVC industrial textiles is an efficient and high-quality production method with broad application prospects and development potential. With the continuous advancement of technology and the continuous changes in the market, the production line will continue to upgrade and improve, providing strong support for the production and development of PVC industrial textiles.
