Title: Shiyong Xia: Innovator in Biodegradable Materials
Introduction
Shiyong Xia is a notable inventor based in Guangdong, China. He has made significant contributions to the field of biodegradable materials, holding two patents that showcase his innovative approach to sustainable technology.
Latest Patents
One of his latest patents is for a kind of biodegradable polyester and its preparation method. This invention relates to biodegradable co-polyester product technology, with a number-average molecular weight ranging from 6000 to 135000 g/mol. The molecular weight distribution is between 1.2 and 6.5, and the crystallization temperature ranges from 15°C to 105°C. This new polyester material overcomes the disadvantages of existing products and can be processed into various forms, including membrane materials, sheet materials, and foam materials. The improved heat resistance allows for applications in long-cycle processing, such as injection processing, while maintaining excellent mechanical properties.
Another significant patent by Shiyong Xia is for a semi-aromatic polyamide and a method for its preparation with low wastewater discharge. This semi-aromatic polyamide is produced by introducing aromatic dicarboxylic acid and aliphatic diamine containing 4 to 14 carbon atoms into an autoclave for prepolymerization. The innovative aspect of this method is the recycling of wastewater generated during polymerization, which greatly reduces overall discharge and improves the utilization rate of raw materials.
