With the deepening of reform and opening up, household appliances have penetrated into thousands of households and become an indispensable part of family life. The development process of home appliance enterprises has also been transformed from short supply to fine and personalized services. "Price, quality" has become a white-hot competition

 

How to reduce the cost at the same time, achieve quality improvement? Kaimeng products through the application experience in home appliance industry, especially in copper, aluminum, stainless steel, stainless iron and other materials used in the product, has a wealth of chemical polishing, passivation antirust, cleaning and other successful applications.

A new method to remove weld spot instead of manual grinding

As we all know, modern home furnishings are characterized by practicality and beauty, in which metal parts play an extremely important role in the combination of the two. Therefore, in the process of furniture manufacturing, the complex metal welding technology is often used. In the process of welding, in order to maintain the beautiful effect of furniture, the oxide skin of the welding part is often polished and then processed manually, which leads to the problem of neither high efficiency nor environmental protection. To solve the above problems, Kaimeng provides a new electrochemical process to solve this problem. The feature of this process is that by cooperating with a small stainless steel bead treating machine, and then dipping the bead treating agent specially matched by our company, the welding spot can be quickly removed by simply brushing on the surface, and the effect is remarkable, so that the treated welding part will show its original luster, which is beautiful and efficient. This process has been popular with Douyin and customers love it.

Improve corrosion resistance to meet the requirements of outdoor stainless steel furniture

Outdoor furniture is on the basis of satisfying practicability, it is more important and picky to the requirement of phenomenon of not easy to produce rust in bad natural environment. In most people's understanding, stainless steel is not easy to rust material, however in halogen or in a humid environment, or the chlorine element in the sea air, dust in the air and acid rain, often easy to rust, threatening the surface of stainless steel furniture. However, the above problems can not be overcome only by mechanical manufacturing, and even in the process of grinding and welding forming has already caused certain damage to the corrosion resistance of stainless steel.

 

In view of this situation, Kaimeng and domestic well-known furniture enterprises to carry out in-depth cooperation, jointly developed a series of environmental protection passivation process. The corrosion resistance of workpieces treated by Kaimeng technology can be improved by 30 times on the original basis. Even close to the military industry on the surface of the strict requirements. Guaranteed products in the harsh external environment can maintain long-term luster without rust, widely praised by customers.

To provide furniture with non - fingerprint processing scheme

Furniture plays an indispensable role in the use and decoration of families and public places. Besides the functional requirements, people also have higher and higher requirements for the appearance. Many customers worry about how to reduce the surface fingermarks and pollution caused by the external environment in the use of the product, keep the surface of the furniture as new and achieve visual satisfaction. Some customers will try to use titanium dioxide and acrylic acid and other methods to form a physical hard membrane on the surface, although the short-term surface of furniture can be maintained without being polluted, but always treat the symptoms.

 

In response to the above requirements of customers, Kaimeng researched and developed an electrochemical treatment process to form a selective oxide film on the surface of stainless steel to solve the above problems. After the treatment of the product, no fingerprints, not easy to be polluted by the environment, keep the product surface clean for a long time, but also greatly improve the corrosion resistance of the product itself. By controlling the parameters of the electrochemical process, the surface with different brightness can be obtained to meet the needs of different customers.

To improve the corrosion resistance of powdered aluminum furniture

Most aluminum furniture enterprises in order to improve the corrosion resistance of their products, the conventional practice is to do leather grinding treatment before powder spraying, leather grinding treatment process is still in the majority of trivalent chromium, although the passivation effect is good but pollution of the environment, not environmental protection. However, the average value of bare test MSS is only about 200H for the chrome-free process in the market, which cannot meet the high requirements of customers for corrosion resistance.

 

In order to meet the high requirements of high-end customers for product quality, Kaimeng has developed two kinds of environmental protection and chromium free passivation process, one is natural passivation, and the other is a new process that can make pale yellow passivation film on the surface according to customer requirements, to meet the needs of online monitoring. The process features green environmental protection, fast passivation speed, no need for meter adjustment, save the complicated process flow, greatly improve the production efficiency. The process can pass the coating test MSS2500h above, to solve the customer's requirements for high corrosion resistance.

Environmental protection alkaline deoiling process of aluminum furniture

At present, the majority of aluminum furniture enterprises are still using acid deoiling process, in which the acid process is dominated by chemical components such as fluorine, sulfuric acid and nitric acid. This process will not only cause damage to the product surface, but also difficult to be implemented under the current severe environmental protection policy. Seeking environmental protection alkaline oil removal process has become an urgent common pain point for enterprises. Because aluminum is a special amphoteric metal, corrosion will occur in the environment of acid or alkali. So how to achieve the cleaning effect under the condition of not corroding the workpiece surface has become a big problem.

 

In 2019, Kaimeng Company developed a new alkaline environmental protection oil removal process that does not contain phosphorus, nitrogen, COD and does not damage the surface of aluminum materials through hard research, development and innovation. The new process does not need heating, nor does it need complex wastewater treatment to solve the problem of environmental protection oil removal. Instead of the previous acid oil removal process, it has a broad prospect. Kaimeng customers have put it into use in large number, and get unanimous praise from customers.

Quick removal of the material in the process of grinding yellow spots

In the stainless steel furniture industry, especially the surface drawing process, the product after drawing treatment is more common because of high temperature will produce a layer of light yellow oxide film. In order to ensure the aesthetic appearance of the product surface, the oxide film is often removed by manual polishing. In the context of the rapid rise of labor costs and the increasingly high requirements of workers on the operating environment, the artificial polishing process will make enterprises bear a large cost.

 

Kaimeng combined with the pain points of customers, targeted research and development of this problem, developed a kind of environmental protection organic weak acid, and surfactant compound made of quick cleaning agent to solve the above problems. When using, it can be used according to the severity of the surface oxide, and can be reasonably controlled without waste. Just place the workpiece in the cleaning agent soak for 3-5 minutes, you can remove the surface oxide skin to restore the original color of stainless steel. To achieve environmental protection, high efficiency, low cost in line with the customer's processing process.
