In China, traditional high-temperature anti-corrosion coatings have faced significant challenges. One major issue is that they often cannot withstand the required temperatures, and secondly, many are made from organic materials that lack sufficient corrosion resistance at high temperatures. As a result, many industrial equipment pieces suffer from severe metal corrosion, leading to frequent failures and increased maintenance costs. For example, a roasting furnace used in sulfur dioxide production can reach up to 600°C, with corrosive gases and mechanical stress causing rapid degradation of the furnace body. In one case, a 40mm thick metal plate corroded within just three months due to the absence of an effective protective coating. Another furnace, operating at 1300°C, suffered severe corrosion from strong chemical fumes, disrupting production and causing significant waste of resources.
To address these issues, Beijing Zhisheng Weihua Chemical Co., Ltd. has developed the ZS-811 high-temperature anti-corrosion coating. This innovative product was jointly researched by universities and military research institutes and holds exclusive patent technology. It is the only domestic company producing and selling this type of material. The ZS-811 coating can endure temperatures up to 1800°C, is water-based, and inorganic, making it environmentally friendly. It does not emit harmful substances even at high temperatures and cures naturally at room temperature. Its physical and chemical properties meet international standards, offering excellent hardness (up to 8H) and long-term protection against corrosion and oxidation.
When applied to high-temperature furnace metals, the ZS-811 coating provides reliable protection against harsh environments. It enhances acid and alkali resistance, prevents oxidation, and ensures a durable seal. Unlike conventional coatings, which tend to peel, crack, or discolor under extreme heat, the ZS-811 coating remains stable and functional. Its high impact and wear resistance make it ideal for industrial applications where durability is crucial. By extending the lifespan of furnaces and reducing downtime, this coating supports continuous production and improves overall efficiency.
The ZS-811 high-temperature anti-corrosion coating has a wide range of applications, including aerospace, petrochemicals, metallurgy, power generation, and military systems. It is suitable for use on chimneys, steam pipes, heat exchangers, high-temperature furnaces, and engine components. With ongoing technological advancements, the demand for this coating is expected to grow, further expanding its role in protecting critical infrastructure across various industries.
Door Viewers
The door observer is a small optical instrument installed on the door of a residence, which is convenient for residents to observe the outdoor situation. Has become a necessity for home safety.
It is composed of a concave lens (objective lens) and a convex lens. The focal length of the objective lens is extremely short, it makes the outdoor person or object into an upright and reduced virtual image, which falls just within the focus of the eyepiece, and finally a reduced upright virtual image is obtained, which is exactly at the clear viewing distance of the human eye. Nearby, you can see the situation outside the door clearly.
