First generation glass ceramic

Back in the mid to late 1990s, pure glass-ceramic plates featuring a wollastonite crystalline phase were already well-established and mass-produced. This innovative material made several appearances at major domestic and international building materials exhibitions, generating widespread interest and attention from industry professionals and consumers alike.

Following this, several invention patents emerged focusing on the composite of glass-ceramic pellets on ceramic tile surfaces. One notable example was the patent filed by Dai Changlu and his team on January 5, 2000, titled "A New Production Method of Glass-Ceramic Ceramic Composite Bricks." In fact, their research in this field had begun as early as 1997. The first prototypes of ceramic microcrystalline composite panels were produced by the original Beijing Beichen Ceramics Co., Ltd. around that time.

Between 1998 and 1999, various companies such as Inner Mongolia Dongsheng Dongqiao Ceramics Co., Ltd., Beijing Ceramics Factory, Foshan Dongpeng, Daewoo Glaze, and Ou Shennuo were approached for collaboration. However, due to multiple challenges, the industry struggled to turn these scientific innovations into commercial success. The main issue was that the first generation of glass ceramics—those based on the wollastonite crystal phase—had significant problems with porosity, which made it difficult to achieve consistent and reliable production.

By around 2002, several major manufacturers in Foshan, including Bode, Xinzhongyuan, Jiajun, and Ou Shennuo, managed to achieve industrial-scale production. Through continuous improvements and practical experience, the pore-related issues of the first-generation glass ceramics were gradually resolved or minimized. As a result, the products were successfully launched into the market. A key milestone was the birth of the world's first self-developed "Seiko Jade" by Bode in August 2002, which was also patented as a national invention. This marked the official emergence of mainstream microcrystalline stone.

The first-generation microcrystalline glass-ceramic composite boards featured a smooth, jade-like appearance with a soft yet bright luster, excellent hardness, wear resistance, and strong resistance to acids and alkalis. However, because the crystallization process grew inward from the edges of the retained particles, the resulting patterns were somewhat limited in variety and lacked visual diversity.

Check Valve

Industrial check valves are wildly used in all type of industrial pipelines, such as power stataion, petrochemical, natual gas,water treatment ect. Swing Check Valve, wafer check valve, titling disc check valve, piston check valve, disc checkvalve, lift check valve and API 602 Check Valve with ASME & DIN & EN & GOST standard are commonly used by customer. Industrial check valve we provided can cover size from 1/2 inch to 48 inch(DN15-DN1200) matching pressure from class 150 to class 2500(PN10-PN420) which are suitable for operating in the working media temperature from -196℃ to 693℃, as well as material in carbon steel, stainless steel, alloy steel and duplex steel in casting material or forging material.
