In the field of bathroom casting copper, the quality of sand core has always been a key factor affecting the quality of castings. For a long time, the sand used for bathroom casting copper is faced with various difficulties such as large fluctuation of silica sand quality, frequent sand core problems and many casting defects. However, Lianxin Casting Sand Group, Wuhan University of Technology and Huazhong University of Science and Technology jointly developed"Special sand for sanitary ware" has brought a new upgrade to the sanitary ware cast copper industry.

There are many problems in the traditional sand for bathroom casting copper. The unstable quality of silica sand leads to uneven solidified layer of sand core, easy to absorb moisture and fracture, crisp sand core structure and large amount of gas. These problems not only affect the strength and stability of the sand core, but also directly lead to defects such as sand sticking, porosity, shrinkage cavity and deformation in the casting. These defects not only reduce the aesthetics of castings, but also affect their performance and life, and bring huge economic losses to sanitary ware enterprises.

In the face of these challenges, Lianxin Casting Sand Group, in conjunction with Wuhan University of Technology and Huazhong University of Science and Technology, has successfully developed through in-depth experimental research and development."Special sand for bathroom". This special sand is treated with high cleanliness on the surface of silica sand to make it more conducive to resin bonding, thereby improving the strength of the sand core. At the same time, by optimizing the silica sand grain type, it has a high roundness, which is more conducive to sand core molding, so that the sand core is more dense, the casting cavity is more smooth. In addition, the special sand for sanitary ware also adopts a smooth air channel design, which improves the air permeability and collapsibility of the sand core, so that the heat can be better transferred to the inside of the sand core, thereby improving the quality of the casting.

Another highlight of the special sand for sanitary ware is its silica sand interface treatment. Lianxin Casting Sand Group uses advanced coating technology to introduce refractory materials on the surface of silica sand, which effectively reduces the tendency of sand sticking in the casting cavity. This innovative technology not only solves the problem that the traditional sand core is easy to stick sand, but also improves the surface quality of the casting, making the bathroom products more beautiful and durable.

It is worth mentioning that the special sand for sanitary ware is used in the north. The headquarters of Lianxin Casting Sand Group is located in"China sand capital" reputation of Liaoning Zhangwu. Liaoning Zhangwu is rich in northern wind-deposited sand, which has the characteristics of good particle size distribution, small angular coefficient, less mud content, good air permeability and high product stability. Northern sand has a unique advantage in the field of bathroom casting copper, which can significantly improve the quality and stability of castings.

Lianxin special sand for sanitary ware can significantly reduce the production cost of sanitary ware enterprises. Due to the characteristics of high cleanliness and high roundness, the production process of the sand core is simpler and more efficient, the amount of resin added is reduced, and the production cost is reduced. At the same time, the excellent performance of the special sand for sanitary ware also reduces the occurrence of sand core problems and casting defects, and improves the production efficiency and product quality of the enterprise.

Up to now, the annual sales of all kinds of casting sand by Lianxin Casting Sand Group have exceeded.100million tons, with annual sales exceeding5Billion yuan, cooperative enterprises more2000Home. While all kinds of products produced by Lianxin Casting Sand Group sell well all over the country, it also has a more stable supply channel, higher product testing standards and better quality control.

In this era full of opportunities and challenges, Lianxin casting sand group Lianxin bathroom special sand with its excellent performance and stable quality, is becoming a leader in the bathroom copper industry. We have reason to believe that the injection of northern sand into R & D and innovation genes"Lianxin bathroom special sand", through scientific and technological innovation and continuous R & D investment, will continue to introduce more high-quality products and make greater contributions to the prosperity of the bathroom industry.
