Non-stick coating spray, surface coating, non-stick adhesive coating, wear-resistant and non-stick spray.

Introduction to Thermal Spraying Non-Stick Coatings—Part I: Application Fields of Non-Stick Coatings 1. Disposable Hygiene Products Equipment: - Rubber and plastic processing machinery and molds; - Woodworking, papermaking, and printing machinery; - Shoes, apparel, and packaging industries. The non-stick coatings are applied to drive rollers in equipment such as coating machines, printing presses, dyeing machines, adhesive tape production machinery, and diaper production machinery. Typically, certain drive rollers in these devices come into contact with coated surfaces, printed surfaces, or dyed surfaces. If the printed or dyed surfaces are not fully dried, they can easily contaminate the roller surfaces, affecting the surface patterns of the final products. Traditionally used Teflon coatings have a high peel strength against hot melt adhesives, resulting in insufficient non-stick performance and inadequate wear resistance. This leads to rapid loss of non-stick properties, reduced production efficiency, shorter maintenance cycles, and increased costs. Our factory has independently developed and patented a “Thermal Spraying Anti-Adhesive and Wear-Resistant Coating” technology that employs plasma thermal spraying. This coating uses a nickel-based alloy matrix dispersed with high-molecular anti-adhesive materials and leverages the biomimetic lotus leaf effect. As a result, the coating exhibits extremely low adhesive peel strength and outstanding wear resistance. Its overall performance is dozens of times superior to that of Teflon coatings, reaching a domestically advanced level in this field. Main Applications: 1. Surface treatment of hot-forming dies; 2. Surface treatment of conveyor rollers in diaper manufacturing machines; 3. Surface treatment of various coating rollers in adhesive machinery; 4. Non-stick surfaces for food processing machinery; 5. Surface treatment of various roller-type components in coating machines. II. Performance Characteristics of the Non-Stick Coating The newly invented anti-adhesive and wear-resistant coating developed by our factory addresses the shortcomings of traditional non-stick coatings—such as Teflon—used in various industrial fields. These traditional coatings suffer from excessive peel strength against hot melt adhesives, leading to poor non-stick performance and insufficient wear resistance, which in turn cause the non-stick properties to fail prematurely. Our new coating significantly improves non-stick performance, extends service life, reduces maintenance intensity and frequency, enhances equipment utilization efficiency, and boosts product quality while lowering production costs. Key features of the coating include: 1. The coating does not adhere to various tapes, glues, adhesives, or hot melt adhesives. 2. Hardness: HV800 3. Roughness: Ra3.2~6.4 4. Temperature resistance range: 0–450℃ 5. Thickness: 0.15–0.3 mm III. Effectiveness of the Non-Stick Coating This coating is made from a high-strength alloy with a surface hardness reaching HRC60, and its bond strength with the substrate reaches 25 MPa. It boasts wear resistance and service life that are unmatched by Teflon coatings. The non-stick performance is exceptional, with an adhesive peel strength against hot melt adhesives of less than 5 g/25 mm. When commonly used hot melt adhesives in the paper products industry are applied to the surface of this coating and then cooled, the adhesive layer can be easily peeled off by hand without leaving any residue—a remarkable non-stick effect. Compared to Teflon coatings, the adhesive peel strength on this coating is significantly reduced. When hard objects such as iron sheets are used to scratch the coating surface, the Teflon coating is immediately scratched, exposing the underlying substrate and losing its non-stick properties. In contrast, after multiple scratches, our coating remains intact and shows no significant reduction in non-stick performance. Field trials conducted on disposable hygiene products equipment have demonstrated a marked improvement in the efficiency of handling adhesive contamination during the production process, greatly enhancing both product quality and production efficiency. This coating solves key technical challenges faced by this equipment and the entire industry, making it highly practical and worthy of widespread adoption.

Tungsten carbide wear-resistant coating applied by dispersion disk spraying

1. Specialized isolation layers for lithium equipment and tungsten carbide wear-resistant coatings applied to dispersing disc surfaces—tungsten carbide wear-resistant coatings are now widely used in the lithium-battery slurry industry and are suitable for various components in lithium battery equipment, including dispersing discs, helical shafts, spiral mixers, wear-resistant parts of pulverizers, tank bodies, cylindrical vessels, conical hoppers, powder-handling machines, feeders, electrode manufacturing equipment, and other wear-resistant coatings. 2. The hardness of the tungsten carbide coating reaches above HRC75, making it one of the hardest and most wear-resistant coatings after diamond. It effectively prevents metal ions from entering the powder, thereby avoiding metal contamination of the powder caused by material wear. 3. Guangzhou Sanxin utilizes American Plazex supersonic spraying equipment and imports high-quality tungsten carbide materials. Tungsten carbide coatings are particularly well-suited for applications involving particle abrasion. 4. During coating application, the workpiece temperature does not exceed 150 degrees Celsius, ensuring no deformation occurs in the workpiece. 5. The coating’s surface roughness is around R3.2, with a controllable coating thickness ranging from 0.10 to 0.35 mm. After pore-sealing treatment, the coating does not react with NMP. 6. Depending on the specific operating environment, you can select wear- and corrosion-resistant coatings tailored to your needs.

Tungsten Carbide Spraying and Coating Process

What is the hardness of tungsten carbide thermal spray coatings? Theoretically, tungsten carbide thermal spray coatings can achieve a hardness of 65 to 70 HRC—this represents the theoretical hardness attainable by domestic thermal spraying technologies. When applying tungsten carbide coatings to sealing surfaces, the process also increases the difficulty of subsequent grinding and lapping operations; therefore, it is recommended to use diamond abrasive paste for grinding. If the sealing surface is a hard seal, repeated opening and closing may affect the integrity of the tungsten carbide coating—this should be taken into account. I.
