In the field of industrial protection such as pipeline engineering and steel structure engineering, corrosion is the core problem that affects the service life of equipment and substrate. Compared with the traditional anti-corrosion coating, the anti-corrosion adhesive tape has become the mainstream anti-corrosion sealing material at present because of its advantages of convenient construction, stable performance and strong adaptability. It is widely used in oil and gas pipelines, municipal water supply and drainage pipelines, outdoor steel structures and other anti-corrosion scenes, and is an indispensable and important material in the industrial anti-corrosion system. Anti-corrosion adhesive tape is a functional material compounded with polymer substrate and special anti-corrosion hot melt adhesive layer. Common substrates include polyethylene, polypropylene, non-woven fabrics, etc., and the adhesive layer mostly adopts butyl modified adhesive, hot melt anticorrosive adhesive and other systems, which has excellent air tightness, waterproof and chemical stability as a whole. The finished adhesive tape is solvent-free, pollution-free, and has balanced physical properties. It can resist the corrosion of water vapor, oxygen and acid-base media for a long time, isolate the corrosion source from the outside, and realize long-term anti-corrosion protection. From the perspective of core performance, the protective ability of anticorrosive tape mainly depends on three core characteristics. The first is the barrier performance. The dense adhesive layer structure can completely block the penetration of air and moisture, put an end to the contact between the substrate and corrosive media, and reduce the problems of corrosion and aging from the root. Secondly, the weather resistance. The anticorrosive tape with optimized formula can adapt to the change of temperature difference, and it will not crack and fall off in low temperature environment, and it will not soften and flow in high temperature environment, and it can maintain stable performance after long-term outdoor use. Finally, the adhesive layer has good viscoelasticity, which can closely adhere to irregular surfaces such as curved surfaces and joints of pipes and steel structures, fill tiny gaps and avoid protective blind spots. According to the material and function, anti-corrosion tape is mainly divided into homogeneous polyethylene anti-corrosion tape, butyl modified anti-corrosion tape, composite thickening anti-corrosion tape and other categories. There are differences in substrate thickness, adhesive layer ratio and tensile strength among different categories, which meet the engineering requirements of different protection levels. The basic adhesive tape is suitable for corrosion protection of conventional municipal pipelines, while the modified thickened adhesive tape is mostly used for protection of high-pressure oil and gas pipelines and steel structures in severely corrosive environments, and the protection standards under different working conditions can be adapted by adjusting the material formula.

The quality of the finished product of anticorrosive tape depends not only on the formula of raw materials, but also on the accuracy of production technology and production equipment. Anticorrosive compounds are mostly high-viscosity hot-melt materials, which require extremely high control of processing temperature, coating uniformity and composite tension. In the production process, temperature fluctuation will directly affect the fluidity of adhesive layer, leading to uneven thickness and insufficient adhesion. Unstable tension will cause the base material to fold and delaminate, which will greatly reduce the anticorrosion performance of the adhesive tape. Hot melt coating is the core process of anticorrosion tape production. The accuracy, stability and adaptability of equipment directly determine the qualified rate and quality uniformity of finished products. Rui 'an Jiayuan Machinery Co., Ltd., a professional coater manufacturer, has been deeply involved in the field of special production equipment for anticorrosive tapes for a long time. In view of the production pain points of anticorrosive rubber, such as high viscosity, difficult thick coating and easy delamination, the equipment control system, coating structure and tension system have been optimized and upgraded. The equipment is equipped with segmented precise temperature control system, which can independently control the temperature of each link of glue melting, glue conveying and coating, stabilize the fluidity of high-viscosity anticorrosive glue, avoid the problems of glue carbonization, glue breakage and glue accumulation, and ensure the continuous and stable coating process. Relying on the high-precision metering and coating die structure, the equipment can accurately control the coating thickness to ensure that the adhesive layer of the whole roll of adhesive tape is even and flat, and there are no defects such as missing coating and thickness deviation. At the same time, it is equipped with a dynamic self-adaptive tension control structure, which can stabilize the conveying state of the substrate in the process of high-speed production, eliminate common problems such as substrate folding, deviation and adhesive layer delamination, effectively improve the fit between the adhesive layer and various substrates, and stabilize the overall anti-corrosion sealing performance of the adhesive tape. The equipment adopts modular design, which is suitable for the mass production of anticorrosive tapes with different specifications and modified formulas, and is compatible with the production and processing of new corrosion-resistant rubber compounds, which can effectively reduce the defective rate and replacement cost, and provide stable equipment guarantee for the large-scale, standardized and high-quality production of anticorrosive tapes.
